[0002] Molds refer to various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. Injection molds are one of the most common types of molds, used in the production of various mechanical parts.

[0003] Existing molds only include a punch and a die. When in use, the punch and die are snapped together, and the injection molding material is injected between the punch and die through the injection hole to complete the injection molding process.

[0004] However, in actual use, after injection molding is completed, the injection molded product inside the cavity mold needs to be removed. There are two ways to do this: the first is electric ejection and the second is manual ejection. Electric ejection requires electric power and is therefore limited by the power equipment. If it is damaged or the power is cut off, it cannot be removed. Manual ejection, on the other hand, is prone to damage to the removal part due to uneven force. Utility Model Content
