Description

TECHNICAL FIELD

[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment for making various shape plastic products by using thermoplastic or thermosetting plastic. It is divided into vertical type, horizontal type and full electric type. Injection molding machine can heat plastic, apply high pressure to molten plastic, and make it fill the mold cavity. The working principle of injection molding machine is similar to that of syringe for injection. It is by the pushing force of screw (or plunger) that the molten plastic in plasticized state (i.e. viscous flow state) is injected into the closed mold cavity, and the process of obtaining the product is achieved after solidification and setting.

[0003] After the injection molding part is demolded, it is often necessary to anneal or humidify to treat the injection molding part and improve the quality of the injection molding part. The existing injection molding part uses annealing to eliminate the internal stress of the injection molding part. However, during the process of moving the injection molding part from the injection molding machine to the annealing equipment, the temperature or humidity around the injection molding part is affected, which causes the temperature of the injection molding part to drop, resulting in the extension of the annealing time of the injection molding part. This not only affects the production efficiency, but also may cause oxidation, deformation and other adverse changes of the injection molding part under high temperature for a long time.
