摘要： PROBLEM TO BE SOLVED: To provide an injection molding apparatus for two-material molding having a mold platen and a mold structure eliminating accompanying movement of the rotary die plate and peeling of moldings.
SOLUTION: The injection molding apparatus for two-material molding has two sets of injection units which plasticize different resin materials for injection charging. It has an attachment/detachment mechanism capable of mutual adhesion opening of (1) rotary dies 6A and 6B and a fixed die 4 or (2) a rotary die plate 9 and a fixed die plate 2 and a checking mechanism checking that the movable die plate 9 separates at a specified distance. On die releasing after charging of a resin into the die, after (1) the rotary dies 6A and 6B and the fixed die 4 or (2) the rotary die plate 9 and the fixed die plate 2 are adhered temporarily with the attachment/detachment mechanism, and, after checking that the movable die plate 3 separates at a specified distance, the adhesion of the rotary die plate 9 and the fixed die plate 2 is released.
