technical field

The utility model relates to a mold, in particular to an injection mold with a water blowing device.

Background technique

Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to melting plastic by heat. The injection molding machine injects into the mold cavity under high pressure, and after cooling and solidifying, the molded product is obtained.

In order to speed up the molding speed in the mold cavity, modern injection molds often use water to cool the mold cavity. After cooling, some water will remain in the water channel in the mold, which will easily cause the inside of the mold to rust for a long time and reduce the mold. In addition, modern molds lack moving measures, especially some large molds, which are very troublesome to carry.
