[0001] The utility model relates to the technical field of cooling the mold of an injection molding machine, in particular to a cooling mechanism for the mold of an injection molding machine. Background Art

[0002] Injection molding machine mold, referred to as injection mold, is a tool used to manufacture plastic products. It usually consists of two parts, one is the molding cavity, and the other is the cooling system. The molding cavity is the template of the plastic product, and its shape determines the shape and size of the final plastic product. The cooling system is used to quickly cool and solidify the molten plastic for subsequent operations.

[0003] However, it still has the following disadvantages in actual use:

[0004] When the existing injection molding machine mold is produced, since the entire mold is not independently provided with a cooling mechanism, the molding mold is usually injected into the mold, and the molding mold is demolded after waiting for natural cooling and molding. It takes a long time to cool the mold, resulting in the inability to quickly produce the next batch of molds, which reduces production efficiency. In addition, long-term cooling can easily cause the temperature in the cooling device to rise, thereby reducing the cooling rate. Utility Model Content
