Filter Housing Mould Insert

The auto part, air filter core shell, is injection-molded and integrally formed. The gap between the middle joints of the product is relatively small, and has a certain depth. There is almost no way to make the cooling water path by the traditional manufacturing method, resulting in the surface of the product being over-temperature due to excessive temperature. The skin texture is severely deformed and the product qualification rate is low. The part is printed on a HBD metal 3D printer. According to the characteristics of the product, design the conformal cooling channels and simulate the effect, and then the mold insert containing the conformal waterway is embedded into the mold by means of metal 3D printing. The effect achieved: the temperature of the insert body is reduced from 120℃ to 50℃; the cooling cycle of the product is greatly shortened, the original cooling cycle is shortened to 45 seconds from 120 seconds, and the production efficiency is increased by 2.5 times; the surface of the product completely meets the requirements. There is almost no distortion.
