VerticalRubber Injection Molding Machine

1. Small footprint: the injection device and clamping device of vertical injection molding machine are located on the same vertical centerline, and the mold opens and closes along the vertical direction, so the footprint is only about half of the horizontal machine, which makes the production efficiency relatively high.
2. Facilitate insert molding: The mold surface faces upward, making it easy to place and insert inserts, which makes insert molding easy to achieve.
3. Maintain accuracy: the weight of the mold is supported by the horizontal template, this design is conducive to maintaining the accuracy of the machine and the mold, avoiding problems caused by mold gravity.
4. High degree of automation: vertical injection molding machine is suitable for the configuration of various automation devices, including simple manipulator, easy to realize automated production.
5. Good seismic resistance: due to the low center of gravity, the vertical injection molding machine has good seismic resistance, verified by many earthquake tests.
6. Advantage of small-lot trial production: simple mold structure, low cost, easy to disassemble and install, especially suitable for small-lot trial production.
7. Plasticization: The transformation of solid rubber granules or lumps into a molten state, i.e., a viscous flow state, by means of heating and shearing. This process usually involves the rotation of the screw and the heating of the barrel.
8. Injection: Molten rubber is injected into the mold cavity at a certain pressure and speed under the push of the screw. The role of the screw in this process is to provide enough pressure to ensure that the rubber fills all corners of the mold.
9. Holding pressure: After the injection is completed, the screw maintains a certain pressure to make up the shrinkage of the molten rubber to ensure the denseness and dimensional stability of the product. The length of holding time depends on the thickness and complexity of the product.
10. Cooling: After the holding pressure is completed, the rubber in the mold begins to cool and solidify. During this process, the cooling system of the mold is responsible for removing heat from the mold, ensuring that the rubber product maintains its correct shape and size.
11. Demolding: After cooling is complete, the mold opens and the product is removed from the mold. This process may require the use of an ejector mechanism or other demolding device.
12. Trimming: The removed product may need to be trimmed to remove excess flash or burrs.
13. Inspection: The finished product is inspected to ensure that it meets quality standards.
