Description

Technical Field

[0001] The utility model relates to the technical field of waste recycling, in particular to a waste recycling device for injection molded parts. Background Art

[0002] During the injection molding process of the injection molding machine, unqualified products and waste such as the connection parts removed from the injection molded parts will appear. These waste materials are collected and then transferred to the granulation workshop for granulation as recycled resources for reuse. Since unqualified products and other waste materials usually have various shapes, the waste materials occupy a large space, which is not convenient for collection and transportation.

[0003] After searching, it was found that a Chinese patent with publication number CN207140156U discloses an injection molding waste recycling and compression device, which includes a frame, a compression cylinder, a pressing block, a bottom plate, a bottom plate locking mechanism and a heater. The compression cylinder is longitudinally arranged on the upper part of the frame, and the upper and lower ends of the compression cylinder are through-connected; the bottom plate is connected to the lower end opening of the compression cylinder via the bottom plate locking mechanism in an openable and closable manner; the pressing block is longitudinally movably arranged in the compression cylinder; the heater is arranged on the outer wall of the compression cylinder; and the upper side of the pressing block is connected to a hydraulic drive mechanism.

[0004] The device compresses the waste in the compression cylinder by means of a pressing block, and at the same time uses a heater outside the compression cylinder to heat the waste to soften it or even partially plasticize it, so that the space occupied by the waste is fully compressed while the waste can maintain a certain shape; the transfer operation requires less space, thereby improving the transfer efficiency, and the waste maintains a certain shape, making it easier to carry. However, the device still has some disadvantages. Due to the different sizes of injection molding waste, it is not convenient to compress injection molding waste of larger sizes. For this reason, we propose an injection molding waste recycling device. Utility Model Content
