Description

Technical Field

[0001] The utility model relates to the technical field of mold cooling, in particular to a mold point cooling device. Background Art

[0002] In the foundry industry, die-casting molds are very commonly used components. In order to facilitate production and save mold materials, die-casting molds have thick-walled parts and thin-walled parts. Due to the high temperature characteristics of liquid metal, the thin-walled part of the mold is easily heated up due to heat conduction. In severe cases, the thin-walled part will be deformed, which will affect the size and quality of the product and greatly reduce the qualified rate of the product. In order to overcome this problem, people use the method of spot cooling to reduce the temperature of the thin-walled part, thereby ensuring the size and quality of the product.

[0003] CN202222801376.5 introduces a point cooling structure for an aluminum die-casting mold, in which a water inlet is connected to an external water source, and the water inlet transmits the water source to a connected arc-shaped water pipe, which transmits the water source to each part of the fixed plate. At the same time, multiple arc-shaped water pipes fill the water storage bend with water flow, and the interior of the multiple water storage bends is provided with a rotating shaft through a bearing rotation, and the end of the arc-shaped water pipe is connected with a water outlet. The water flow stirs the turbine blades inside the water storage bend to rotate along the rotating shaft, slowing down the speed of the water flow, and the slow water flow fully absorbs the heat generated by the aluminum die-casting mold during the aluminum hot liquid casting, and then discharges a large amount of heat through the water outlet, which reduces the temperature of the template to the greatest extent, prevents the template from deforming, and improves the qualified rate of the produced aluminum products. However, the cooling structure is not convenient for detecting the water temperature inside it, and the continuously flowing water is not conducive to fully absorbing the heat, and it is not convenient to fully utilize the temperature difference of the water for heat transfer, which is relatively inconvenient to use.
