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

Embodiment Construction

[0018] Next, a specific implementation of a cooling system for a mold and a casting process according to the present invention will be described in detail with reference to the accompanying drawings.

[0019] attached figure 1 Shown is a schematic structural view of the cooling system for the mold described in this specific embodiment, including a mold body 10 and a cooling device. The cooling device is water-cooled and includes a plurality of cooling units that are closely attached to the surface of the mold body 10 . The mold body 10 described in this embodiment is a mold for an automobile wheel hub. According to the structural characteristics of the mould, the cooling unit includes a PCD water cooling 21, a lower mold slope water cooling 22, a rib water cooling 23, a rib tail water cooling 24, a shunt core water cooling 25, an Surface water cooling 26, upper mold slope water cooling 27 and side mold rib tip water cooling 28.

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 invention relates to casting engineering, in particular to a cooling system for molds and a casting process. 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 rapidly cooling the mold and the molten metal in it after injecting the molten metal into the mold. The metal after cooling and forming is taken out of the mold, and then undergoes 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 heat of the mold surface is taken away by the cold air 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 high-pressure air with a pressure of 4-6 kg for the low-pressure casting mold. It n...
