Vertical injection molding machine is a mechanical equipment, usually composed of injection system, mold clamping system, hydraulic transmission system, electrical control system, lubrication system, heating and cooling system, safety monitoring system, etc. The injection system is one of the most important components of a vertical injection molding machine, and generally has the following main types: plunger type, screw type, screw pre-plastic plunger injection type, etc. The most widely used type is the screw type. Its function is to heat and plasticize a certain amount of plastic within a specified time in one cycle of the injection molding machine, and then transfer the molten plastic to the plastic at a certain pressure and speed through the screw. Plastic is injected into the mold cavity.
So as a commonly used injection molding equipment, what are the characteristics of vertical injection molding machines?
1. The injection device and the clamping device are on the same vertical center line, and the mold is opened and closed in the up and down direction. The floor space it occupies is only about half of that of a horizontal machine, so its productivity is about twice as high when converted into floor space.

2. Easy to achieve insert molding. Because the mold surface faces upward, it is easy to place and position the insert. By adopting a model with a fixed lower mold plate and a movable upper mold plate, fully automatic insert molding can be easily achieved by combining a belt conveyor device with a robot.
3. The weight of the mold is supported by the horizontal template for up and down opening and closing movements. The phenomenon of the template being unable to open and close due to the gravity of the mold, like the horizontal machine, will not occur. It is helpful to maintain the accuracy of machinery and molds for a long time.
4. Each plastic part cavity can be taken out by a simple robot, which is conducive to precision molding.
5. Generally, the surrounding of the clamping device is open, which makes it easy to configure various types of automation devices and is suitable for the automatic molding of complex and delicate products.
6. The belt conveyor device can be easily installed in the middle of the mold, which is convenient for automatic molding production.
7. It is easy to ensure the consistency of resin fluidity and mold temperature distribution in the mold.
8. Equipped with rotating table, moving table and inclined table, it is easy to realize insert molding and in-mold combination molding.
9. During small-batch trial production, the mold structure is simple, low-cost, and easy to unload.
10. Having withstood the test of many earthquakes, vertical machines have better earthquake resistance than horizontal machines due to their low center of gravity.
