Cavity Heat Conduction High Temperature Resistant Metal Die Casting Mold

Abstract

The invention discloses a cavity heat-conducting high-temperature resistant metal die-casting mold, which comprises a front mold and a rear mold. The front mold and the rear mold respectively include a mold plate with a cavity formed on the inner surface and made of mold steel. A template load-bearing plate set corresponding to the template and fixedly connected, and a heat dissipation mechanism, the front mold is also provided with a die-casting mechanism, and the rear mold also includes an ejection mechanism; wherein the heat dissipation mechanism It includes a heat transfer and heat conduction cavity formed by a pattern plate and a pattern plate load-bearing plate at intervals, a heat conduction part of a heat conduction channel communicating with the heat transfer heat conduction cavity is formed inside, and a heat transfer part is used for heat exchange with the heat conduction part to the circulating water tank, The heat transfer chamber and the heat conduction channel form a closed space. The present invention utilizes a vacuum heat transfer chamber to conduct heat dredging and setting on the template, and utilizes the external design of the circulating water tank, which can effectively increase the heat exchange area with water, improve the temperature control effect, and utilize the high thermal conductivity of the vacuum heat transfer medium, The overall thickness of the mold can be effectively controlled. Compared with the built-in waterway mold, the overall processing cost and thickness are effectively controlled.

Description

technical field [0001] The invention belongs to the technical field of mold manufacturing, and in particular relates to a cavity heat-conducting high-temperature-resistant metal die-casting mold. Background technique [0002] Steel balls or other steel castings need to use pouring molds in the production process. The traditional casting method generally uses sand casting, that is, sand molds need to be made first when pouring; when sanding, the mold moves more times, and the molten steel uses The rate is low, the finish of the finished product is low, the phenomenon of falling sand is serious, and the pouring time is long, and there are also pollution problems. [0003] In order to solve these problems, sandless casting molds are mostly used at present. But existing casting mold generally comprises left and right two formworks, and mold cavity and sprue are provided relatively in the middle part of two formworks, and two formworks are closed up during pouring, promptly adop...

Problems solved by technology

[0005] When the finished product is taken out after casting, due to the tight bonding between the finished product and the cavity, it is often necessary to use a special demoulding tool to complete it, and it is generally manually operated, which is labor-intensive and costly

[0006] Moreover, when performing die-casting, after the die-casting head is in contact with and extruded by molten metal, when the finished product is taken out, due to the tight adhesion between the finished product and the cavity, especially the indenter, it is often necessary to use a special demoulding tool to complete , and most of them are manually operated, which is labor-intensive and costly

At the same time, there is also a problem of tight bonding between the prepared product and the mold
