Injection mould product ejection apparatus and method

摘要

An injection mold product ejection apparatus comprising: an ejection element; and a displacing member for displacing the ejection element between a retracted molding position and a first extended ejection position; wherein, the ejection element is an ejection assembly and comprises: a) an inner ejection sub-assembly, and b) an outer ejection bush surrounding the inner ejection sub-assembly, said displacing member comprises: a collective displacing member, for displacing the whole ejection assembly from the retracted molding position to an intermediate ejection position, and a sub-assembly displacing member, for converting the ejection assembly from the intermediate ejection position to the first extended ejection position by extending the sub-assembly relative to the outer ejection bush.

1. An injection mould product ejection apparatus comprising:
an ejection element; and a displacing member for displacing the ejection element between a retracted moulding position and a first extended ejection position; wherein: the ejection element is an ejection assembly and comprises: a) an inner ejection sub-assembly, b) an outer ejection bush surrounding the inner ejection sub-assembly, and c) an outer surface forming a moulding die for shaping the injection mould product, said displacing member comprises: a) a collective displacing member, for displacing the whole ejection assembly from the retracted moulding position to an intermediate ejection position, and b) a sub-assembly displacing member, for converting the ejection assembly from the intermediate ejection position to the first extended ejection position by extending the sub-assembly relative to the outer ejection bush, wherein the sub-assembly displacing member comprises: a driving member for extending the sub-assembly relative to the outer ejection bush, a connecting member for connecting the sub-assembly with the driving member and transmitting the driving force from the driving member to the sub-assembly, a lock for locking the sub-assembly in the retracted position, and a limit stop for limiting the extension of the sub-assembly.
