Technical Field

[0001] The utility model relates to the field of injection molds, in particular to an injection mold with high efficiency cooling. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products. In the production process of the handle lower cover, injection molds are needed for rapid production.

[0003] However, the current injection molds still have some shortcomings. For example, the existing injection molds have low cooling efficiency, which causes the workers to wait for a long time during the injection molding process before the handle lower cover in the mold cools and takes shape, which interferes with the workers' product processing efficiency to a certain extent, and thus there are certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model studies and improves the existing structural deficiencies and provides an injection mold with efficient cooling. Utility Model Content
