Description

Technical Field

[0001] This utility model relates to the field of injection molding product manufacturing equipment, and in particular to a cutting fixture for injection molding product material handles. Background Technology

[0002] Injection molding product sprue cutting fixture is a tool or device used to cut off excess sprues generated during the injection molding process. In the injection molding process, the sprue is the plastic flow channel that connects the molded product to the injection molding machine barrel, and it usually needs to be removed after molding.

[0003] When using existing injection molding product material cutting fixtures, the material is first picked up by a robot and placed into the cutting fixture. At this time, the sensor on the fixture detects the presence of material, the clamping cylinder presses down on the product, and the cutting cylinder cuts it. After completion, the clamping cylinder releases. This process is less than the robot's delay time. Then the robot picks up the product and places it on the conveyor belt. After cutting, the material bundle falls into the collection box through the guide box for unified processing. However, when using existing injection molding product material cutting fixtures, the cylinder-driven clamping block is usually a rigid structure. If the fixture positioning accuracy is insufficient or the curvature and flatness of the product surface are inconsistent, it may lead to excessive or insufficient local pressure.

[0004] Therefore, it is necessary to provide a new type of injection molding material and cutting tooling to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cutting fixture for injection molded product material handles.

[0011] Preferably, the fixing plate and the operating platform are each provided with a plurality of material dropping holes.

[0012] Preferably, a material collection box is movably connected to the operating platform.

[0013] Compared with related technologies, the injection molding product material cutting fixture provided by this utility model has the following beneficial effects:

[0014] With the fixed device in place, when it is necessary to fix the injection molded product, the servo motor is first started. The servo motor drives the threaded rod to rotate. While the threaded rod is rotating, it drives the movable plate to move.
