[0002] At present, injection molds are a tool for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes.

Therefore, an injection molding demolding device is urgently needed to solve this problem. Utility Model Content
