Abstract

This utility model relates to a demolding device for rubber processed products, including a support frame fixed to the left side of the lower mold and a collection hopper fixed to the right side of the lower mold. A cutting frame is slidably connected to the surface of the support frame. Both the support frame and the surface of the lower mold are connected to a conveyor belt via rotating rollers. This utility model relates to the field of rubber processing technology. In this demolding device, the pusher cuts off the flash at the connection between the flash and the finished rubber product. Simultaneously, the cutting head moves along with the pusher to perform a secondary cut. When the cutting frame is in position, a drive mechanism drives the turntable to rotate. At this point, the cutting head is located on the side of the molded workpiece, and the cutting head performs a circular motion to cut off the molded product, preventing adhesion to overflowing rubber residue. This device not only removes flash but also assists in demolding the molded product, achieving thorough separation and better processing results.
