Description

Technical Field

[0001] The utility model relates to the technical field of a rapid demoulding ejector device, in particular to a rapid demoulding ejector device for producing plastic milk tea cups. Background Art

[0002] Most milk tea cups are made of plastic, and plastic cups usually need to be processed by injection molding. Plastic cup injection molding is a common plastic processing technology, also known as plastic cup injection molding. It is a process of heating and melting plastic particles and injecting them into a mold, and then cooling and solidifying to form a plastic cup. Injection molding demolding refers to the operation process of removing plastic products from the mold during the injection molding process. Demolding is a very critical step in the injection molding process, which directly affects the quality and production capacity of the product.

[0003] However, if the demolding force is too small, the product may be deformed or unable to be completely demolded, while if the demolding force is too large, the product or the mold may be easily damaged. In some existing devices, the plastic cup is mostly ejected by an ejector pin during demolding. However, in actual use, due to the high temperature of the plastic cup, it is easy to leave marks on the surface of the plastic cup during ejection, which affects the molding quality of the plastic cup. In addition, some plastic cups will adhere to the surface of the ejector pin, making demolding difficult. Therefore, it is urgent to solve the above problems. Utility Model Content
