Automobile injection molded part cooling device

Abstract

The invention belongs to the technical field of automobile manufacturing and particularly relates to an automobile injection molded part cooling device. The device comprises a lower mould body, a lower cooling pipe is arranged on the lower mould body, and a first liquid inlet and a first liquid outlet are formed in the two ends of the lower cooling pipe correspondingly and extend to the outside ofthe lower mould body; an upper mould body is arranged on the top side of the lower mould body and matched with the lower mould body, an upper cooling pipe is arranged on the upper mould body, and a second liquid inlet and a second liquid outlet are formed in the two ends of the upper cooling pipe correspondingly and extend to the outside of the upper mould body; and a condenser, a reservoir and avariable frequency pump are fixedly mounted on the top side of the upper mould body, and a first flow splitting pipe is mounted in a water inlet of the condenser and connected with the first liquid outlet and the second liquid outlet through leather hoses correspondingly. According to the cooling device, injection molded parts are convenient to cool, the cooling effect is good, data including thetemperature, the pressure, the flow rate and the like are convenient to observe in real time, and the product quality can be better controlled.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a cooling device for automobile injection molding spare parts. Background technique [0002] The processing and production of auto parts requires injection molding, and many metal parts need to be manufactured by die-casting. Die-casting refers to the casting method of filling the mold cavity with molten alloy under high pressure and high speed conditions, and cooling and forming under high pressure. It is a casting process. Die casting is one of the most widely used and fastest-growing metal thermal forming techniques in China. Die casting, as an advanced non-ferrous alloy precision parts forming technology, adapts to the complexity, precision, light weight and energy saving of products in modern manufacturing industry. According to the requirements of globalization and greenization, the application fields are constantly expanding. [0003] In the d...

Problems solved by technology

[0003] In the die-casting process, the temperature is directly related to the quality of the casting. The temperature control in the die-casting process only depends on the heat exchange of the die-casting mold. However, in the initial injection stage of the die-casting process, if the temperature is too low, it will cause liquid molten alloy. Rapid solidification affects the fluidity of the molten alloy and cannot fill the entire cavity. In the pressure holding stage of the die-casting process, if the temperature is too high, it will cause casting defects. The existing die-casting device is not convenient to control temperature and pressure, and it is not convenient to Real-time observation of temperature, pressure, flow and other data cannot better control product quality and meet customer needs
