Abstract: A resin part includes a plate-shaped molded main body that is constituted of an injection-molded product. Of plate surfaces of the molded main body, a surface on an opposite side to a surface requiring surface accuracy constitutes a pressure-application surface to which pressure is applied by a movable insert. A parting line is formed on the pressure-application surface by the movable insert to satisfy the following relationship: (t/4)≤x≤(3t/2), where x is a distance from an end edge part of the molded main body to the parting line and t is a thickness of the molded main body.

Abstract: A resin part includes a molded main body that has a plate shape with a longitudinal direction and is constituted of an injection-molded product. The resin part has a gate portion that is a vestige of a resin injection gate. The gate portion is located in an end face part of the molded main body to cross a position corresponding to a center of gravity of the molded main body; the end face part extends in the longitudinal direction of the molded main body.

Abstract: In a molding die, movable die elements are respectively received in die element receiving holes formed in a frame plate. An end surface of the frame plate, which faces a cavity at a location that is other than locations of the die element receiving holes, forms a frame portion compression surface. An end surface of each movable die element, which faces the cavity, forms a split compression surface. Die element drive devices respectively drive the split compression surfaces of the movable die elements. A whole compression plate commonly supports an opposite end part of the frame plate and opposite end parts of the movable die elements, which are opposite from the cavity. When the whole compression plate is moved forward, the whole compression plate integrally drives the frame plate and the movable die elements forward. A whole drive device drives the whole compression plate.
