[0002] In the production and processing of injection molded products, after the injection molded parts are demolded, there is a gate connected to the injection molded part body remaining in the runner of the injection port. Since the presence of the gate will affect the normal use of the injection molded part, it is necessary to grind and remove it so that the product becomes the required shape.

[0003] Currently, when using the gate removal tooling for injection molded parts, it is necessary to fix the injection molded part first. However, usually only a single injection molded part can be fixed at a time, resulting in only one injection molded part's gate being removed at a time, making the removal efficiency low. And during the removal process, waste chips are likely to fly, posing a certain safety hazard, and at the same time, the waste chips cannot be collected. Summary of the Utility Model
