技术领域technical field
本实用新型涉及压铸机散热技术领域，具体为一种用于马达转子压铸机的水冷散热结构。The utility model relates to the technical field of die-casting machine heat dissipation, in particular to a water-cooled heat dissipation structure for a motor rotor die-casting machine.
背景技术Background technique
压铸过程中压铸模的温度直接影响压铸件的质量和生产率。为了保证压铸生产的持续进行，在每一个压铸循环中,液态合金传给模具的热量与模具自然散热及冷却通道散发的热量应保持平衡。为了保持热平衡，必要时，需在内浇道附近进行充分冷却，而在浇注行程末端，除了开设恰当且足够的溢流槽外，还需进行局部加热。The temperature of the die-casting mold during the die-casting process directly affects the quality and productivity of the die-casting. In order to ensure the continuous operation of die-casting production, in each die-casting cycle, the heat transferred from the liquid alloy to the mold and the natural heat dissipation of the mold and the heat emitted by the cooling channel should be kept in balance. In order to maintain thermal balance, sufficient cooling must be carried out near the inner runner when necessary, and at the end of the pouring stroke, in addition to setting up a proper and sufficient overflow groove, local heating is also required.
水冷散热器一般由水冷头、水泵、冷排、水管、水冷液以及风扇组成，水因为其物理属性，导热性并不比金属好，但是，流动的水却有极好的导热性，也就是说，水冷散热器的散热性能与其中散热液流速成正比，制冷液的流速又与制冷系统水泵功率相关。目前压铸机的水冷散热需要结合吹风扇或者增压泵增压的冷却液流遇到散热管壁，大大削弱了冷却液的压力，导致冷却液流速不够，造成散热效率低下。A water-cooled radiator is generally composed of a water-cooled head, a water pump, a cold row, a water pipe, a water-cooled liquid, and a fan. Because of its physical properties, water has no better thermal conductivity than metal, but flowing water has excellent thermal conductivity, that is to say , the heat dissipation performance of the water-cooled radiator is directly proportional to the flow rate of the cooling liquid, and the flow rate of the cooling liquid is related to the power of the water pump of the refrigeration system. At present, the water-cooled heat dissipation of the die-casting machine needs to be combined with the cooling liquid flow boosted by the blower fan or booster pump to meet the wall of the heat dissipation pipe, which greatly weakens the pressure of the cooling liquid, resulting in insufficient cooling liquid flow rate and low heat dissipation efficiency.
现有的压铸机的水冷散热结构存在以下缺陷：The water-cooling heat dissipation structure of the existing die-casting machine has the following defects:
（1）现有的压铸机的水冷散热结构较多散热效率低，无法满足压铸机的散热需求，更有甚者可能会导致压铸效果差；(1) The water-cooled heat dissipation structure of the existing die-casting machine has many low heat dissipation efficiency, which cannot meet the heat dissipation requirements of the die-casting machine, and what’s more, it may lead to poor die-casting effect;
（2）现有的压铸机的水冷散热结构的水冷管壁通常将冷却液动能大大消弱造成冷却液流速慢，管内压力降低，浪费大量能量。(2) The water-cooled tube wall of the water-cooled heat dissipation structure of the existing die-casting machine usually greatly weakens the kinetic energy of the coolant, resulting in a slow flow rate of the coolant and a decrease in the pressure inside the tube, which wastes a lot of energy.
