Cooling system for die and casting process

Abstract

The invention discloses a cooling system for a die. The cooling system comprises a die body and a cooling device, wherein a water cooling mode is adopted for the cooling device; the cooling device comprises a plurality of cooling units clinging to the surface of the die body; each cooling unit independently comprises a water inlet and a cooling pipe; and a water outlet pipe of the cooling unit is selected from one of an independent water outlet pipe and a common water outlet pipe. The invention has the advantages that: a water cooling device is used for replacing the conventional air cooling device, and a large-power air compressor is not needed, so that the energy consumption and noise are lowered; and water cooling has high specificity and high heat transfer efficiency, so that the water cooling efficiency can be increased, the process duration is reduced, and the production efficiency is increased.

Description

Technical field [0001] The present invention relates to casting engineering, in particular to a cooling system and casting process for molds. Background technique [0002] In the field of low pressure casting, mold cooling is one of the indispensable steps. The so-called mold cooling refers to the process of quickly cooling the mold and the molten metal in a certain way after the molten metal is injected into the mold. The cooled metal is taken out of the mold, and then subjected to subsequent grinding and polishing processes. [0003] The existing low-pressure casting cooling system is air cooling, that is, a high-power blower is used to blow cold air into the mold shell, and the cold air takes away the heat from the mold surface to achieve the purpose of cooling the mold. [0004] The disadvantages of the existing air cooling system are as follows. [0005] 1. It is required to provide 4-6 kilograms of high-pressure air for low-pressure casting molds. It needs to be equipped with...

AI Technical Summary

Problems solved by technology

It needs to be equipped with high-power air compressors and related air pipelines, which consumes a lot of energy and maintenance costs

[0006] 2. The noise of 60-80 decibels is emitted when blowing and cooling, which is harmful to the health of colleagues and is not environmentally friendly.

[0007] 3. Use the air flow to take away the heat of the mold body to cool down the mold and castings. The cooling speed is slow, resulting in long casting process duration and low production capacity
