【Abstract】 According to the structure characteristics of the plastic part with inside annular conˉcave,the demoulding method for the moulded plastic part was discussed.The partitioning method and moving course of the core with the adoption of a sequential demoulding mechanism were anˉalyzed,the core-pulling mechanisms for plastic parts of different structure were studied.Two types of the mould structure were designed and attention points for the design were pointed out.更多还原
