Plastic material is a commonly used organic material, which is widely used in the fields of electronic appliances and other digital devices. Injection molding is a method in which heat-melted materials are injected into the mold cavity by high pressure, and after cooling and solidification, molded products are obtained. In industrial production, nozzles are often produced during the molding process of plastic products, and special procedures need to be arranged to cut off the nozzles after injection molding is completed. The traditional method of cutting off the nozzle is to cut it manually with pliers or blades, but the manual cutting has the following disadvantages: (1) It is difficult to place the product on the cutting tool manually to ensure that each product is placed in the same position on the tooling , which affects the size of the product after the nozzle is removed, making the product quality unstable; (2) The manual removal cannot make the product coherent, which reduces the mechanization efficiency and affects the production efficiency of the factory; (3) The manual removal requires One piece of equipment is equipped with many operators, which increases the production cost of the factory; (4) manual cutting is required. Because of the need to use water nozzle pliers or blades, operators are easy to accidentally injure their fingers when working, especially after the operators have worked for a long time. .
