Description

Technical Field

[0001] The present invention relates to the technical field of plastic molding, and in particular to a processing device for plastic molding. Background Art

[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that convert synthetic resins or plastics into plastic products. It is a larger production department in the plastics industry. Plastic processing generally includes plastic batching, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been molded into finished products or semi-finished products, which is also called plastic secondary processing.

[0003] At present, plastic processing generally uses an injection machine to inject raw materials into a mold through an injection nozzle for molding. However, the injection part of a general injection machine does not have a sealing function. Before injection and after injection, the raw materials in the injection nozzle are easy to flow out of the mold, causing a waste of raw materials. At the same time, it is easy to be contaminated by the outside world. In addition, existing processing equipment usually only has a single mold, and it is necessary to stop the machine to take the finished product, which is time-consuming and reduces processing efficiency.
