Door panel mould
The following points were also achieved when designing the temperature control system of this mold:
1) The spacing between the water channels is guaranteed to be between 50 and 60 mm, and the cooling water channel is between 20 and 25 mm from the cavity surface. The heat in the mesh area and the hot nozzle area of this mold is relatively concentrated, so key cooling is performed.
2) Considering the processing problem, the cooling water channel of this mold is kept at least 8 mm away from the push rod, push block and other push holes.
3) The length of the cooling water channel is roughly equal, ensuring that the temperature difference between the cooling water inlet and outlet is roughly equal, thereby ensuring that the mold temperature is roughly balanced.
4) According to the shape of the plastic part, the mold uses a large-angle inclined hole. Although the drill bit has side slip and is very easy to drill off, the problem can be solved by milling a platform perpendicular to the inclined hole before drilling.
