Mold cooling structure for uniformly cooling mold core

Abstract

The invention discloses a mold cooling structure for uniformly cooling a mold core. The structure comprises a mold body and a heat insulation pipe, a cooling water path is arranged in the mold body, and the cooling water path comprises a first cooling channel, a first cooling water circulation channel and a second cooling water circulation channel. The first cooling water circulation channel and the second cooling water circulation channel are symmetrically arranged on the two sides of the first cooling channel, the heat insulation pipe is fixedly installed in the first cooling channel, a partition plate is arranged in the heat insulation pipe, a water passing gap extending towards the interior of the mold body is formed in the bottom face of the first cooling channel, and a water inlet and a water outlet are formed in the heat insulation pipe. The water inlet and the water outlet are symmetrically formed in the two sides of the partition plate, the water inlet communicates with the first cooling water circulation channel, and the water outlet communicates with the second cooling water circulation channel. Compared with the prior art, uniform cooling of the mold core is achieved, and the machining efficiency and the machining quality of products are fully improved.

Description

technical field [0001] The invention belongs to the field of mold cooling, in particular to a mold cooling structure for balanced cooling of mold cores. Background technique [0002] The mold refers to the tool that makes the blank into a workpiece with a specific shape and size under the action of external force. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. [0003] When designing the cooling water channel of the mold, the cooling water usually uses copper or iron to conduct heat to cool the mold core, which leads to the rapid cooling of the part of the conventional cooling water channel that is close to the water well, but the cooling is not in place far away from the water well. Cycle to achieve the ideal mold temperature, which will not only reduce the processing efficiency, but the uneven mold t...
