Technical Field

The utility model relates to the technical field of mold, specifically indicate a submerged formula exhaust mould of injection mould.

Background

The existing injection mold exhaust structure in the industry is divided into a vacuum-pumping type, a mold closing line exhausts and an insert exhausts. The three methods are all based on the premise that gaps need to be designed at the sealing position, and the gaps can be vacuumized. The air can be discharged only through the gap. It is not suitable for the exhaust of injection mold of composite products, such as soft plastic-covered plastic or hardware products. If the conventional three exhaust methods are adopted to design the exhaust structure. The effect is not ideal and leads to local air entrapments of the product. Resulting in a high product failure. In view of the above, we propose a submersible exhaust mold for injection molding to solve the above problems.
