BLOW-MOLDED OBJECT AND ITS DISASSEMBLING METHOD

摘要

PROBLEM TO BE SOLVED: To simply disassemble a housing 5 from a resin material 6 in forming a lamp 1 by secondarily injecting the resin material 6 in the abutted part of a lens part 2 split-molded by primary injection and the housing 5. SOLUTION: The resin material 6 and the housing 5 are selected from materials not adhered to each other and brought into contact with each other by a contact surface 7 due to undercut for regulating the drawing-out of them. The housing 5 has a gap S in a through-hole 5b for attaching the terminal, and compressed air is supplied from the gap S to forcibly draw the housing 5 from the resin material 6 to disassemble the used lamp 1.
