Embodiment Construction

[0026] Examples such as Figure 1 to Figure 3 As shown, an injection mold cooling system for easy demoulding includes a concave mold 1 and a convex mold 2 arranged on the left and right. The concave mold 1 is fixed with two guide tubes 3 arranged up and down, and the guide tubes 3 are inserted into the convex mold. In the guide hole 21 of the mold 2;

[0027] The die 1 is formed with a cavity 11 with a right opening and a first cooling cavity 12 with a left opening. The outer wall of the cavity 11 is formed with a plurality of first annular grooves 13. Inside the first cooling cavity 12 A cooling water turning part 4 is fixed, and a groove 41 matching the outer wall of the cavity 11 is formed in the cooling water turning part 4, and a U-shaped sinking groove 42 is formed in the groove 41;

[0028] The water outlet main channel 43 and the water inlet main channel 44 which are arranged up and down and communicate with the U-shaped sinker 42 are formed in the cooling water trans...

Abstract

The invention discloses an injection mold cooling system facilitating demolding. The injection mold cooling system comprises a female mold and a male mold, and cooling water runners are formed in theinner side of a mold core of the male mold and the outer side of a mold cavity of the female mold; cooling water enters from a water inlet main runner of a cooling water transfer part, and then the cooling water is divided into two paths to respectively flow towards the cooling water runners formed in the inner side of the mold core of the male mold and the outer side of the mold cavity of the female mold and finally enters a water drainage main runner of the cooling water transfer part; and the male mold and the female mold convey cooling water through guide pipes. According to the injectionmold cooling system, by rapidly cooling the mold cavity and the mold core, the time for cooling a plastic product is shortened, the demolding quality of the plastic product can be improved, and meanwhile, the production efficiency of the plastic product is improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold cooling system that facilitates demoulding. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products 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 injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. Existing injection molding equipment has certain disadvantages in use. After the processing is completed, the mold will generate a higher temperature, which makes the plastic product unable to cool and solidify quickly, reduces the processing efficiency, and easily causes deformation and pattern of the plastic product, which bri...
