The exhaust groove is an important part of the plastic mold design, which can discharge the excess gas generated in the mold. Avoid gas from hindering the normal filling speed of the plastic melt, and prevent the gas compression from generating excess heat and causing the part to burn.

Plastic mold

1. In order to facilitate the manufacture and cleaning of the mold, the exhaust groove should be set on the side of the concave mold of the parting surface as much as possible.

2. The exhaust groove is preferably set at the end of the material flow and the part with a relatively thick wall, which can make the mold exhaust smoother

3. From a safety perspective, the exhaust direction cannot be aimed at the staff, and the exhaust groove should be made into a curved or bent shape to avoid scalding the workers when the gas is sprayed.

4. The width and size of the exhaust groove need to be designed according to the mold structure, but the plastic raw material must not be allowed to enter the exhaust groove to block it or flow out of the mold.

5. The overflow of the plastic is related to the exhaust gap. It is necessary to determine a reasonable exhaust gap according to the characteristics of different plastics, which can effectively avoid excessive overflow that affects the appearance of the molded parts.
