Technical Field
[0001] The utility model relates to the technical field of post-processing devices for plastic products, in particular to a shearing device for cutting off large gates of plastic products. Background Art
[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material, including products made from injection molding, vacuum forming and other processes. Plastic is a type of synthetic polymer material with plasticity. Plastic products manufactured using ordinary injection molds all have gates, and the gates of these plastic products must be removed after demolding.
[0003] At present, when shearing the large gates of plastic products, workers usually place the plastic products on some cylinder-driven shearing devices. As the cylinder-driven shearing knife descends and cuts toward the gate position of the plastic product, the plastic product and the gate can be pressed and cut apart. However, the large gates of some plastic products are prone to retain some edges after pressing and cutting, resulting in the large gates of the plastic products requiring manual inspection and manual trimming by workers later, which makes shearing of large gates of plastic products more cumbersome. To this end, we propose a shearing device for cutting off large gates of plastic products. Utility Model Content
[0004] The main purpose of the utility model is to provide a shearing device for cutting off large gates of plastic products. A hot cutting mechanism is provided at the shearing table and the pressure cutting seat. The hot cutting mechanism enables a heated cutter structure to be present at the telescopic rod of the pressure cutting seat. The heated cutter is pushed by the telescopic rod on the flat connecting plate, and the cutter can be pressed down to thermally cut off the large gate on the surface of the shearing table, so that residual edges are less likely to appear at the cutting point between the plastic product and the large gate, thereby ensuring a good shear separation of the plastic product and the large gate, simplifying the shearing processing steps of the plastic product and the large gate, and effectively solving the problems in the background technology.
