The exhaust system of the Plastic speaker housing cover mould is so important that we should pay attention to the following factors when designing:
(1) The exhaust groove should be designed on the parting surface as much as possible and on the concave mold as much as possible;
(2) The exhaust groove should be designed at the end of the material flow and the thicker part of the plastic part as much as possible;
(3) The exhaust direction of the exhaust slot should not face the operator, and it is best to be curved to prevent scalding the worker during injection;
(4) The size of the exhaust groove is usually 1.5～1.6mm wide according to experience, and the groove depth is 0.2～0.5mm, so that the material does not enter the exhaust
The groove is suitable, and it should be smaller than the non-overflow gap of the plastic. Checking the literature [1] found that the minimum non-overflow gap of ABS is 0.04～0.06mm. So we can take the groove depth as 0.02mm
Cooling system of Plastic speaker housing cover mould
(1) Try to make the distance between all cooling pipe holes and the surface of the outer cavity equal;
(2) In the mold of plastic parts with large shrinkage, a cooling circuit should be arranged along the shrinking direction;
(3) Strengthen the cooling at the gate;
(4) Avoid opening the cooling pipe in the fusion pattern of the plastic part;
(5) Pay attention to the sealing problem of the water pipe to avoid water leakage.
