Enter aiutage, be then discharged outside to by branch pipe.With the liquid level more and more higher of plastic liquid, plastic liquid extruding is slided
Motion block, makes sliding shoe overcome the upward lifting of the elastic-restoring force of elastic component, and sliding shoe is pressed further by the air in aiutage, made
It is discharged by branch pipe.Check valve can avoid the air in the external world from entering by branch pipe in aiutage.Pass through the utility model, energy
It is enough to realize exhaust process twice, effectively the air in forming cavity can be discharged.Outside air can also be avoided to enter simultaneously.
The utility model can effectively avoid producing stomata in moulding.
2. the diameter of pod apertures gradually increases from top to bottom so that sliding after partly plastic fluid enters pod apertures and cooled down
Motion block easily can depart from therewith.
3. setting sealing ring, the gas in forming cavity is avoided by being flowed out between sliding shoe and aiutage so that sliding shoe
It can bear more to upward pressure, be advantageous to the air in sliding shoe extrusion aiutage.
4. setting limited block, it is capable of the position of limit slippage block, excessive plastic liquid can be avoided to enter in aiutage,
So as to preferably keep the face shaping of moulding after demoulding.
