[0001] The invention belongs to the technical field of blanking of injection molding machines, and more specifically, relates to a blanking device. Background Art

[0002] At present, injection molding machines generally rely on robots when unloading materials. The robots are equipped with end clamps. The suction cups on the end clamps take out the injection molded parts and place them in the material frame.

[0003] However, in practice, there is a situation where one mold can produce multiple parts. One injection molding may produce two or more injection molded parts, and they do not belong to the same injection molded parts. Therefore, after unloading, a worker is required to classify the injection molded parts taken out each time and put them into the corresponding material boxes. In this way, the worker needs to work next to the injection molding machine, which poses a safety hazard. The end clamp is relatively small and the material box is relatively large. The end clamp cannot directly put different injection molded parts into each material box. Summary of the invention
