    Abstract: This invention relates to an injection molding method using an injection mold. The method comprises (1) a molten resin injection step for injecting the molten resin from a gate into a cavity, (2) a pressure-keeping step for continuously applying pressure from the gate after the molten resin injection step, and (3) a fluid injection step for injecting a fluid toward the back surface of the molded product. The pressure-keeping step and the fluid injection step are simultaneously executed.Simultaneously executing these two steps can lower the pressure that is to be continuously applied from the gate. The present injection molding method can reduce the pressure of the fluid to be injected toward the back surface of the molded product in order to cause the back surface of the molded product to separate from the cavity surface.

    Abstract translation: 本发明涉及一种使用注射模具的注射成型方法。 该方法包括：（1）熔融树脂注入步骤，用于将熔融树脂从浇口注入空腔;（2）在熔融树脂注入步骤之后连续地从浇口施加压力的压力保持步骤，以及（3） 流体注射步骤，用于将流体注射到模制产品的背面。 同时执行压力保持步骤和流体注入步骤。 同时执行这两个步骤可以降低从门连续施加的压力。 本注射成型方法可以降低要注射成型品的背面的流体的压力，以使模制品的背面与空腔表面分离。

    Abstract: 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.

    Abstract: The invention relates to a method for injection molding a plastic molded part in an injection mold, comprising a) injecting a specified amount of plastic melt into the injection mold; b) introducing a compressed fluid between a part of the wall of the injection mold and the injected plastic melt; c) allowing the plastic melt to cool until the plastic molded part is self-supporting; and d) removing the plastic molded part from the mold. The invention specifies that, during or after step a) and during or before step b), the cavity of the injection mold is sealed against the environment, preferably by activating at least one seal.

    Abstract: A mold apparatus and method is used to form a solid injection molded plastic part having no internal voids, a Class A finish, a sink-free exterior appearance surface, and unevenly distributed structural detail extending from the opposite surface, the detail including free-standing reinforcement ribs, attachment bosses, and the like. In sequence, a seal groove in the mold cavity is reduced to a pressure below atmospheric (i.e., negative), a charge of hot thermoplastic is introduced into the mold cavity and seal groove whereby to form a gas seal ring, and pressurized gas is injected into the mold cavity. The pressurized gas forces the hot plastic from one mold half against the other mold half, and the gas seal formed by the plastic prevents gas on one side of the thermoplastic from reaching the appearance surface of the part.
