Background
The cooling system of the injection mold is an important component of the injection mold, and directly influences the quality and the production efficiency of the produced product. The cooling time of the die accounts for about two thirds of the whole production cycle period, and the key for improving the production of the die is to shorten the cooling time.
High-temperature plastic melt entering the cavity needs to be cooled and solidified to release heat, the mold emits the heat to the air in modes of conduction, convection, radiation and the like, but more than 70 percent of the heat needs to be taken away by cooling water. Therefore, the size, shape, number and distribution of the cooling water channels in the mold are beneficial to improving the cooling efficiency of the mold.
The cooling water channel of the plastic mould is usually drilled on the mould or the template by a machining method, when the mould cavity of the mould is complex, the machining method is difficult to realize that the water channel and the mould cavity are basically shaped, and a cold area or a hot area possibly appears in the mould cavity, so that the cooling speed of each part of the plastic part is uneven, and thermal deformation is generated.
The insert in the center of the die core of the traditional main airbag cover plate die cavity of the automobile is located in the center of the die, the temperature of the position is highest, and the insert needs higher cooling speed. However, the central insert has a complex shape and a small thickness, and cannot be used for manufacturing a cooling water channel in a machining mode, so that local temperature of a die is too high and cooling is too slow, and product quality and production efficiency are seriously affected.
