Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, and more specifically, to a filtering device for an injection molding machine. Background Art

[0002] The injection molding machine is a machine that extrude the raw materials after heating them by rotating the screw. The screw generates extrusion thrust, which can turn the raw materials from solid into molten melt. After compression and mixing, it is finally discharged from the injection molding machine and injected into the shoe mold to form the sole.

[0003] When raw materials are added into the injection molding machine, they will be screened through a filter to block raw materials that are too large so that they cannot enter the injection molding machine for mixing and stirring. This can reduce the probability of reduced mixing degree and improve product quality.

[0004] However, the filtered raw materials will accumulate on the filter screen, making it impossible for subsequent raw materials to pass through the filter screen, thereby reducing the feeding speed.

[0005] Therefore, the present application provides a technical solution to solve this technical problem. Utility Model Content
