The present invention makes full use of the advantages of a resin molded stator while pursuing advantages related to performance, reliability, and workability. Provided is an axial gap-type rotary electric machine comprising: a stator in which a plurality of core units having a magnetic flux surface in the rotational axis direction are arranged annularly around the rotational axis; a rotor facing the magnetic flux surfaces of the stator in the axial direction; a housing comprising an inner cylinder space in which the stator is accommodated; and a molded resin that covers part or all of the stator and integrally connects the stator and the inner circumference of the inner cylinder space. The housing comprises an annular thick wall section that has a predetermined thickness toward the axial center side and that follows the inner circumference in part of the inner circumference of the inner cylinder space. The axial boundary of the molded resin and the inner circumference of the inner cylinder space is included within the area of a radial projection surface of the thick wall section.

An interior part for a vehicle is formed by core-back expansion molding. The interior part includes a foamed plastic body formed by injecting a foamable plastic resin into a mold and separating the mold portions of the mold to allow foaming expansion of the foamable plastic resin. An edge portion of the foamed plastic body includes a projecting freeze section and a core-back expansion radius located adjacent to the projecting freeze section. The projecting freeze section is formed in a freeze seal area of the mold adjacent a parting line to help prevent excessive flashing of material at the parting line during separation.

A resin injection molding method uses a mold having a cavity and a hole-forming columnar body. The hole-forming columnar body is movable in an axial direction while extending through the cavity, and includes a first diameter portion having a first diameter, a second diameter portion having a diameter greater than the first diameter, and a tapered portion having a diameter gradually increasing from the first diameter portion toward the second diameter portion. The method includes moving the hole-forming columnar body in the axial direction such that at least one of the first diameter portion or the tapered portion is positioned in the cavity, injecting the molten resin to fill the cavity, maintaining an inside of the cavity under pressure, moving the hole-forming columnar body in the axial direction such that the second diameter portion is positioned in the cavity, and solidifying the injected filling molten resin.

A conductive member module has a pair of conductive members formed in a plate shape and facing each other, and a sealing part for sealing the pair of conductive members. The conductive member module is produced by performing an accommodation step, a sealing step, and an extraction step. In the sealing step, the conductive members are sealed with a resin injected into a die while a force is applied by the resin to the individual conductive members in directions to approach each other in a facing orientation of the pair of conductive members.

Provided is a liquid silicone molding die, including a first mold base, having at least one first molding zone and a feed hole on one side thereof and having a feeding mechanism coupled to the feed hole on the other side thereof, wherein the feeding mechanism is coupled to an injection machine to inject a raw material, and a heating element is provided around the first molding zone; and a second mold base, operatively facing or separating from the first mold base, corresponding to the side of the first mold base and correspondingly provided with a second molding zone, an injection channel, a sealing ring groove and a sealing ring.

Provided is an injection molding device, including an injection port arranged on an upper mold base; an upper mold arranged in the upper mold base, wherein at least one ejection port, a gasket groove and a gasket are provided and the ejection portion is connected to the injection port; a lower mold base operatively aligned with or separated from the upper mold base and provided with at least one gas passage for the gas to enter or exit; and a lower mold disposed on the lower mold base. The lower mold base is aligned with or separated from the upper mold base, the lower mold is provided with a mold cavity and at least one shaped air path is provided to connect the mold cavity with the gas passage. The lower mold is a porous material and has a plurality of pores. Gas is pre-injected into the mold cavity through the gas passage and at least one air path to maintain a preset pressure inside the mold cavity. Gas is spewed out through the plurality of pores, thereby causing a finished product to exit the mold cavity. In addition, the present disclosure also provides an injection molding method.

Mold including a first shell having a cavity, a second shell having a projection, and an intermediate shell having a projection suitable for being coupled in the cavity of the first shell and a cavity suitable for being coupled with the projection of the second shell. The second shell includes a first injection channel extending from an inlet hole in a side wall of the second shell to an outlet hole in the projection of the second shell. The intermediate shell has a second injection channel extending from an inlet hole in a side wall of the intermediate shell to an outlet hole in the projection of the intermediate shell.

An apparatus for injecting a molten plastic material into a mold is described. The apparatus includes a heated manifold (manifold) with channels to distribute molten material inside it, and a heated injector, to inject molten material to the mold cavity, equipped with a translatable shutter to regulate the flow of the injected molten material.

An actuator is attached to the manifold to receive molten material from it to send to the injector and move the shutter. The actuator includes a piston connected to the plug, and a first conduit to bring a pressurized fluid from the outside to the piston. A plate includes a second internal conduit to bring pressurized fluid to the injector, where a gap separates the plate and the actuator.

A connecting member is mounted to cross the gap and carry pressurized fluid from the plate to the actuator.
