Classification of Vertical Injection Moulding Machine
Vertical injection molding machine can be divided into the following categories
The most common type, consisting of injection system, clamping system, hydraulic system, electrical control system and heating or cooling system. Vertical injection, vertical clamping, fixed lower mold, movable upper mold, minimum clamping force of 15T, maximum can reach 300T, high molding accuracy, uniform stress distribution, convenient insert molding, longer mold life. According to product and mold requirements, slide plates can be designed based on the standard machine: single slide plate, double slide plate or right angle slide plate.
Based on the standard machine, a rotating disc structure is added. Through the rotatable disc worktable, multiple molds are installed, so that the molds can be switched between different stations. Molding, cooling and ejection operations can be performed at the same time, which greatly improves production efficiency and saves labor costs.
It has two or more injection units, each unit has independent barrels, screws and other components, which can plasticize plastics of different colors or materials. It mostly adopts a vertical clamping structure, with a rotary or turret device, which can form multi-color products at one time, avoiding secondary processing, saving time and labor costs, and improving production efficiency.
Bakelite injection molding machine and BMC injection molding machine are both injection molding equipment for specific materials. The vertical Bakelite injection molding machine is mainly used for injection molding of thermosetting plastics such as phenolic resin (Bakelite); BMC is also a thermosetting material, but contains longer fiber reinforcement. The two have the same structure, but due to different materials, there will be differences in screw, barrel, temperature control system and process parameters.
C-type machines and K-type machines are mainly divided according to the body structure, and the core difference lies in the different clamping mechanisms and applicable scenarios. The C-type machine has a C-shaped open structure, and the clamping part has no back plate, with a wide operating space and high flexibility. It is suitable for electronic connectors and small hardware inserts. It can be upgraded to a double-slide plate injection molding machine according to product requirements; the K-type machine adopts a closed frame or four-column clamping structure. The front and rear plates are connected by a tie rod. It has a large clamping force and high precision, and the body is rigid. It is suitable for large products, high-precision parts or materials that require high-pressure injection. It can be upgraded to a disc machine or a double-slide plate injection molding machine according to product requirements.
Injection molding equipment specially designed for the production of liquid silicone injection molding products. It has the characteristics of vertical clamping and vertical injection. The structure often adopts a double slide plate or turntable design, with a multi-stage precision mold electric heating temperature control system, equipped with LSR special oil pressure cold closed nozzle, suitable for the molding of various precision silicone parts, such as silicone pacifiers, medical throats, mobile phone internal precision parts and other products.
Adopts the latest technology of multi-cylinder direct locking, the clamping force is evenly distributed, solving the problems of high worktable of large vertical machines, inconvenient operation and complicated mold replacement.
What Products Need to Be Produced on a Vertical Injection Molding Machine
Vertical injection molding machines are typically used to produce parts that have the following characteristics:
Tall or thin profile
Vertical injection molding is well-suited for manufacturing parts with a tall, thin, or upright shape, as the vertical orientation allows the mold to accommodate these geometries more effectively than a horizontal machine.
01
Tight tolerances
The stability and precision of a vertical injection molding setup often allows for tighter dimensional tolerances to be achieved, making it suitable for producing parts that require high precision.
02
Large or heavy parts
Benchmarking machinery has great influence,covering 1,500 companies and 15 well-known enterprises across the country
03
Parts with complex geometries
The vertical configuration can facilitate the injection of material into molds with complex internal features or undercuts, which would be more challenging to fill in a horizontal machine.
04
Delicate or fragile parts
The controlled and stable movements of a vertical machine can be beneficial for molding parts that are easily deformed or damaged, as the part is less prone to shifting or warping during the process.
05
Selection of Vertical Injection Moulding Machine
How to choose a vertical injection moulding machine, because the vertical mold clamping and vertical injection, the upper mold is movable and the lower mold is fixed. Straight injection molding machine is the most optimal solution for injection molding of embedded parts. The most basic four elements of injection molding machine are selected:
1. Product requirements: According to the size and weight of the product, choose a vertical injection molding machine with appropriate clamping force and injection volume; according to the product precision requirements and output requirements, refer to the injection molding machine injection precision, stability and other parameters to select the appropriate model;
2. Plastic raw materials: Due to the different characteristics of different plastic raw material oils, the injection temperature, injection pressure, holding time and other aspects are different. Therefore, when choosing injection molding, it is necessary to choose a model that is suitable for the raw material and has the corresponding molding process parameter adjustment function;
3. Mold size: Products with existing molds need to check whether the column spacing data of the vertical injection molding machine meets the mold size according to the mold size;
4. Production efficiency: Refer to injection speed, opening and closing mold speed and degree of automation. Choosing a vertical injection molding machine with high injection speed, high opening and closing grinding speed, and high degree of automation can better improve production efficiency;
5. Operation and maintenance: The machine should have a simple and easy-to-understand operation interface, convenient operation and parameter setting, which can be carried out more conveniently and quickly during both the operation process and maintenance stage.
First of all, preparatory work to check whether the various parts of the machine and the electrical control box are in good condition. Check the oil level of the hydraulic oil, whether the oil storage is sufficient, and start the motor to observe whether the oil output from the axial plunger valve is normal. Open the cooling water valve to connect the cooling water.
Push the mold transfer mechanism to the highest position, install the plastic mold on the moving mold plate, unscrew the fixed mold plate, correct the upper mold and the fixed mold plate of the plastic mold and tighten the screw, fasten the plastic mold lower mold on the moving mold plate, and run the mold transfer mechanism, check whether the mold position is correct. Barrel heating: Turn on the electric heating switch of the electrical control box, add plastic into the barrel, and fully heat the plastic to melt.
Vertical injection molding machine injection operation: turn on the solenoid valve 8 to make the mold transfer mechanism rise and close the plastic mold, and turn on the solenoid valve 6 to press the injection plunger into the barrel for injection molding. After the injection is completed, the solenoid valve 6 is turned on to push the injection plunger out of the barrel, and the solenoid valve 8 is turned on to lower the mold shifting mechanism, and the plastic mold can be opened and demolded.
Regularly check the electrical parts, remove dirt, oil and dust, keep the electrical contacts clean, and often remove the dirt and dust on the joints. The vertical injection molding machine has accumulated rich experience and common problems in the long-term and large-scale maintenance.
Regularly clean the machine's components, including the mold, barrel, and nozzle, to prevent buildup of debris and ensure proper functioning.
Check the machine's hydraulic system regularly, including the oil level and condition. Change the hydraulic oil as recommended by the manufacturer to prevent wear and tear.
Inspect the machine's electrical components, such as the control panel and wiring, for any damage or loose connections. Address any issues promptly to avoid potential malfunctions.
Lubricate the moving parts of the machine, like the screw and ejector pins, according to the manufacturer's instructions. This helps reduce friction and ensure smooth operation.
Perform preventive maintenance on the mold, such as cleaning, polishing, and replacing worn-out parts, to maintain product quality and consistency.
Monitor the machine's temperature settings, injection pressure, and other parameters to ensure they remain within the optimal range recommended by the manufacturer.
Schedule regular maintenance checks and calibrations to identify and address any issues before they become more serious problems.
Train operators on proper handling and maintenance procedures to ensure the machine is operated safely and effectively.
The Difference Between Vertical Injection Molding Machine and Horizontal Molding Machine
The biggest difference between vertical injection molding machine and horizontal machine lies in the design layout of machines. Vertical machine occupies relatively small area, but the height of machine has certain requirements for the height of a factory. Horizontal machines are very long and require a large area, but the height of machines is relatively low, which will reduce the height requirements of the factory.
Vertical injection molding machines usually need to use lifting platform or small forklift when switching moulds, while horizontal machines can be lifted and switched by driving. Horizontal machines are slightly better at rapidly changing dies. In the aspect of die structure, due to different gravity, multi-slider structure appearing on horizontal machine is seldom used in vertical injection moulding. The corresponding structure of vertical machine usually uses cylinder for core pulling, which is more stable.
Vertical injection molding machines are widely used in the injection molding of wire-encapsulated products, such as connecting wires, various electronic data wires and power plug wires. The characteristics of vertical injection molding machine can produce relatively stable linear products and improve the stability of forming.
