Resin molding device, and method for manufacturing resin molded article

A resin molding apparatus comprising:

• a fixed platen;
• a movable platen that can be raised and lowered by a drive mechanism;
• an intermediate plate arranged between the fixed platen and the movable platen;
• molding dies, each including an upper die and a lower die, one of the molding dies being provided between the fixed platen and the intermediate plate and another of the molding dies being provided between the intermediate plate and the movable platen;
• a pair of side wall members arranged on both lateral sides of the movable platen and the intermediate plate;
• a slide mechanism that causes the intermediate plate to slide with respect to the pair of side wall members;
• and
• a raising-and-lowering linking mechanism that causes the raising and lowering of the intermediate plate to occur together with the raising and lowering of the movable platen;
• wherein
• the raising-and-lowering linking mechanism comprises
• a pantograph mechanism that extends and contracts due to the raising and lowering of the movable platen, and
• a coupling mechanism that couples a cross link part of the pantograph mechanism and the intermediate plate;
• and
• the coupling mechanism has
• a connecting member connected to the cross link part;
• a coupling member that couples the connecting member to the intermediate plate;
• and
• an elastic member interposed between the connecting member and the coupling member.
