A push block ejection mechanism & have spent & have spent Tablet shape plastic parts with flange, such as using push plate ejection will adhere to mold, should use ejector institutions. Because of the block is part of the form cavity, so it should be has high hardness and low surface roughness. & have spent & have spent Its reset form has two kinds: one kind is rely on the plastic pressure reset lever, one is adopted.
2. Use of forming parts ejection mechanism & have spent & have spent Some plastic parts due to the structure shape and the plastic ties, unfavorable use push rod, pipe jacking, push, push boards such as ejection mechanism, forming insert can be used at this time or die out of the plastic parts. Speak in front of the block piece belongs to molding set piece of ejection mechanism.
3. Multielement comprehensive ejection mechanism & have spent & have spent It is to point to will the foregoing several combined ejection device achieves the goal of ejection. Commonly used have a plunger, roof, pipe jacking and roof.
4. Air pressure emergence mechanism & have spent & have spent Use pneumatic demoulding should set aside.
