发明名称 MOLD APPARATUS FOR INJECTION MOLDING AND INJECTION MOLDING METHOD
摘要 PROBLEM TO BE SOLVED: To provide a mold apparatus for injection molding and a molding method which reduce the possibility of occurrence of poor appearances in the periphery of hard-to-release parts during releasing the hard-to-release parts of an injection molding. SOLUTION: The mold apparatus includes a movable-side template 110b having a through-hole 113b and an outer concave portion 115b corresponding to the outside of the outer wall of a tubular portion 11 formed in the peripheral edge of the through-hole 113b, a fixed-side template 110a combined with the movable-side template 110b so as to form a cavity C, with the through-hole 113b communicating with between the movable-side template 110b and the cavity C, a movable insert 130b inserted into the through-hole 113b in a freely movable way and having, at the tip, an inner concave portion 131b corresponding to the inside of the outer wall of the tubular portion 11, a clamping device 400 positioning and fixing the movable insert with the outer concave portion 115b and an inner concave portion 131b in a combined state and a coil spring 140b releasing the movable insert 130b from the inside of the outer wall of the tubular portion 11 when the positioning and fixing operation is released.
