摘要： A resin molding device, resin molding method and resin molded product capable of guiding a sink to an optional position to perform a precise molding. A resin molding metal mold includes a gate formed in the central part of a cavity, a stepped part increasing the opening diameter of the cavity in the circumferential direction orthogonal to the flowing direction of a molten resin introduced into the cavity from the gate, and a fine outside air inlet part circumferentially formed on the outer part from the stepped part. The outside air inlet part is formed of a porous material and allowed to communicate with the outside of the resin molding metal mold through a communicating passage. Accordingly, the molten resin injected into the cavity from the gate is cooled with the outside air introduced from the outside air inlet part formed in the area except a transfer part after the reduction in resin pressure by the stepped part to generate a sink, forming a non-transfer part, so that the transfer property of the transfer part can be improved to enhance the shape precision of the molded product.

摘要： A plastic molding having high accuracy includes at least one transfer surface and at least one imperfect transfer portion having a concave or convex shape. The mold assembly includes a cavity into which molten resin is injected, a slide cavity piece which is capable of being slid at a prescribed time so that a gap is formed between the resin and the slide cavity piece, and a vent hole for supplying a compressed gas in the cavity. A method of producing the plastic molding includes the steps of heating resin to provide a molten resin, injecting the molten resin into a cavity of a molding, applying a resin-pressure to the molten resin, cooling the resin, sliding the slide cavity piece, and opening the mold assembly.

摘要： This invention provides a resin molding device, resin molding method and resin molded product capable of guiding a sink to an optional position to perform a precise molding. A resin molding metal mold 1 comprises a gate 3 formed in the centeral part of a cavity 2, a stepped part 4 increasing the opening diameter of the cavity 2 in the circumferential direction orthogonal to the flowing direction of a molten resin 10 introduced into the cavity 2 from the gate 3, and a fine outside air inlet part 5 circumferentially formed on the outer part from the stepped part 4. The outside air inlet part 5 is formed of a porous material and allowed to communicate with the outside of the resin molding metal mold 1 through a communicating passage 6. Accordingly, the molten resin 10 injected into the cavity 2 from the gate 3 is cooled with the outside air introduced from the outside air inlet part 5 formed in the area except a transfer part after the reduction in resin pressure by the stepped part 4 to generate a sink, forming a non-transfer part, so that the transfer property of the transfer part can be improved to enhance the shape precision of the molded product.
