Resin molding apparatus and method for manufacturing resin molded product

A resin molding apparatus, comprising:

• a molding mold;
• one mold wedge mechanism;
• and
• one mold cavity block driving mechanism;
• wherein
• the molding mold comprises:
• one mold, and the other mold;
• the one mold comprises:
• one mold cavity frame member, and one mold cavity block;
• the one mold cavity block is movable in the one mold cavity frame member in a mold opening/closing direction of the molding mold;
• one mold cavity is formed by a surface of the one mold cavity block facing the other mold and an inner surface of the one mold cavity frame member;
• the one mold cavity block is moved in the mold opening/closing direction using the one mold cavity block driving mechanism;
• a position of the one mold cavity block in the mold opening/closing direction is fixed using the one mold wedge mechanism;
• and
• in a state that the one mold cavity block is moved to a preset height position using the one mold cavity block driving mechanism and a position in a direction away from the other mold in the one mold cavity block having been moved to the height position is fixed to be limited using the one mold wedge mechanism, a resin is injected into the one mold cavity, and thereafter a resin molding is performed by changing a depth of the one mold cavity using the one mold wedge mechanism and the one mold cavity block driving mechanism.
