Abstract

The invention discloses a die cooling structure capable of reducing warpage deformation. The die cooling structure comprises a male die, a female die, a water tank and a mounting frame, the male die and the female die are clamped with each other to form a die core cavity; and the left side and the right side of the die core cavity are respectively provided with a heat dissipation cavity I and a heat dissipation cavity II, and a main pipeline I, four water return pipelines I and a plurality of branch pipelines I are arranged in the male die, wherein one end of each branch pipeline I is connected with the heat dissipation cavity I. Different from the cooling method in which multiple water pipes are distributed in the die in the conventional technical means, the heat dissipation cavity I is used to cool and dissipate heat. The water injection mode in the male die is to inject water into the heat dissipation cavity I through the plurality of branch pipelines I, so that the speed of the cold water entering the heat dissipation cavity I is synchronous. Different from the cooling mode of the heat absorption of the pipeline in the die of the conventional technical means, the warpage deformation possibility of the die core can be reduced through a uniform water injection mode.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a mold cooling structure for reducing warpage and deformation. Background technique [0002] At present, the waterway design of the injection molding mold is usually a straight-through U-shaped circulating water, which is relatively simple in form and has poor temperature control effect. In the injection mold, the cooling system is its core part, which has a great impact on the life of the mold, the production efficiency and quality of injection molded products. all have important influences. The design of cooling water circuit for injection molding is the key to improving the quality of injection molding products and improving the efficiency of injection molding. The influence of the waterway on the quality of the molded product is mainly manifested in the molding of the product. The waterway is used to control the mold temperature, and the change of the mold temperatur...
