Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more particularly to an injection mold with a water blowing device. Background Art

[0002] An injection mold is a tool for producing plastic products and 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 parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine, and after cooling and solidification, a molded product is obtained. In order to speed up the molding speed in the mold cavity, existing injection molds usually need to cool the mold after the product is molded. Currently, the commonly used cooling method is basically to cool the mold with water, that is, a water blowing device. However, most traditional water blowing devices only spray water around the mold, which makes it easy for water to enter the interior of the injection molding device, thereby affecting the molding of the plastic product. Moreover, after cooling, a large amount of water resources will be lost. Each time a model is flushed and cooled, an external water source needs to be connected, which will cause a waste of water resources. Utility Model Content
