Injection mold with uniform and quick cooling capability

Abstract

The invention provides an injection mold for uniform and rapid cooling, comprising a movable mold fixed plate, a movable mold, a fixed mold, and a fixed mold fixed plate, the movable mold is set at the lower end of the movable mold fixed plate, and the fixed mold is set at the fixed mold The upper end of the fixed plate, the lower end of the movable mold is provided with a mold core, and the upper end of the fixed mold is provided with a mold groove. The cooling cavity in the shape of a rotary body, the material of the fixed mold between the mold groove and the cooling cavity is copper, and a refrigerator is embedded in the body of the fixed mold near the bottom edge of its side wall, and the opposite of the cooling cavity An air inlet and an air outlet are respectively arranged on the tops of both sides, an air inlet pipe is arranged between the air inlet and the refrigerator, and an air outlet pipe is arranged between the air outlet and the refrigerator. The invention can quickly and uniformly cool down the product before opening the mold, thereby shortening the production time and improving the precision of the product.

Description

technical field [0001] The invention relates to the technical field of mold design, in particular to an injection mold with uniform and rapid cooling. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. In the prior art, the injection mold first clamps the movable mold and the fixed mold, then injects the fluid material, and then cools it before opening the mold. The cooling process uses the difference in thermal expansion and contraction coefficients between the product and the mold to separate the product from the inner wall of the mold so that the product can be demoulded smoothly after the mold is opened. In this process, the cooling rate and the cooling degree of each part of the product are uniform. Sex is very important. First of all, the speed of cooling will affec...

AI Technical Summary

Problems solved by technology

First of all, the cooling speed will affect the length of waiting time before opening the mold, thus indirectly affecting the production efficiency

In addition, in the case of speed, the cooling of the product after molding is to let the product drop from the temperature above its melting point to the temperature that can be maintained in a conventionally used solid state. Therefore, the uniformity of the cooling degree of each part of the product will affect the product at the same time. The degree of cold shrinkage further affects the precision of the product after molding, and the uniformity of cooling will also affect the cooling rate of the product as a whole
