Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a high-efficiency cemented carbide extrusion mold. Background Technique

[0002] A mold is a variety of dies and tools used in industrial production for injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. to obtain the required products. In short, a mold is a tool for making shaped articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the article's outer shape through the change of the physical state of the formed material and is known as the mother of industry. Extending the mold life is an important factor in reducing the extrusion processing cost. The mold may have the size and shape error of the extruded part exceeding the allowable value due to the longitudinal crack of the female die or the wear of the forming cavity and the die hole. The former can be avoided through correct design and manufacturing, and the latter can be slowed down by correctly selecting the mold material, its heat treatment and surface treatment processes, correctly determining the extrusion process and lubrication, etc. to extend its service life.

[0003] However, it still has some disadvantages. For example, after pouring liquid metal into the mold, high temperature will be generated inside the mold, and the mold cannot be separated until it cools down, and the subsequent processing can be carried out. The waiting process is slow, seriously affecting the work efficiency.

[0004] To solve the above problems, a high-efficiency cemented carbide extrusion mold is proposed in this application. Content of the Utility Model

A pouring port is installed between the upper extrusion mold and the lower extrusion mold. The integrated heat dissipation device is convenient for quickly cooling the mold after the extrusion mold finishes working, so as to obtain the production result faster, and it can be quickly disassembled by itself and can be selectively used, having a good application prospect.
