摘要： In an injection mold having a cavity formed between opposing faces of a fixed mold and a movable mold for defining a shape of a product, and cooling channels formed in the fixed mold and the movable mold, respectively, for cooling resins injected into the cavity, cooling channels of the movable mold are formed at positions at least opposite to those where cooling channels of the fixed mold are not formed, thereby obtaining an injection mold capable of securing uniformity of optical properties of the obtained molded article, such as birefringence and causing no deterioration of mechanical properties of the molded article such as a deflection even when a cooling time is shortened in order to increase cycle of the injection molding.

摘要： An injection moulding tool with optimum temperature distribution as the result of an improved tempering duct system is obtained if the tool inserts (10, 11) are each made up of two or more plates, tempering ducts (12, 12', 12") are worked in from the external faces (F1, F2, F3), on which the parts are subsequently joined by the diffusion welding method. An injection moulding tool for VHS reel hubs produced by this method produces moulds for injection moulding with substantially reduced wobble and a reduced cycle time.

摘要： A cavity member is disclosed for use in an injection molding machine. The cavity member has one portion which includes a molding surface for forming the molded article and a second portion for reducing heat transmission to the first portion. The second portion forms a cap on the nozzle end of the cavity member and includes an aperture aligned with the gate of the cavity member so as to permit plastic from the nozzle of an injection molding machine to enter into the mold. The cap includes channels which can cooperate with pockets in the nozzle end of the second portion for liquid cooling. The nozzle is spaced from the cap by a short distance to provide a thermal break which break can be filled with plastic from the injection molding unit to provide further insulation.

摘要： A method and system for cooling a mold, including the steps of providing fluid flow connectors insertable into a mold for conducting the coolant into the mold. One of the connectors is made in one-piece and includes a threaded stem which threads into a mold opening, and that one-piece also includes two threaded openings which are disclosed transverse to the length of the stem and which align with passageways in the mold for attaching to two tubes extending in the passageways. The system in method is arranged for the alignment of the threaded openings with the passageways while the stem is fluid tightly threaded into the mold opening, and all of these connections are made on the interior of the mold. The threads on the stem are of one diameter which is the maximum pitch diameter of the threaded opening in the mold which receives the stem, and the stem is cut to the appropriate length and its remaining threads are then tapered for fluid tightly threading into the mold opening, all for the purposes mentioned above.

摘要： A parison and core pin construction for a plastic injection blow molding machine of the type wherein a rotatable arm supports at least two such pins in diametrically opposed relationship and alternates them between a separable parison mold over the arm and a separable blow mold below the arm. The pins work in unison. That is, when plastic is injected in the parison mold on top of the pin associated with it, that pin thrusts upon and opens the pin opposed to it and in the blow mold to admit air under pressure to the parison in the said blow mold.

摘要： A forming tool with forced thermal fluid-based spatio-temporal temperature control of a surface of the tool has a subsurface manifold underlying at least a part of a forming surface of the tool and a number P of at least 6 ports, each port fluid coupled respectively to the manifold via respective channels, where the ports exit the tool at disparate points, with each pair of ports in fluid communication via the manifold. This structure allows manifold path diversity for varying thermal fluid supply and drainage. The manifold may be reinforced.

摘要： A movable mold includes a movable mold main body and a gear piece attached to the movable mold main body so as to relatively movable, and having a cavity formation space for forming a cavity. In the gear piece, a piece-side coolant flow path includes an annular flow path surrounding the cavity formation space, a piece-side supply flow path introducing coolant into the annular flow path, and a piece-side discharge flow path introducing the coolant from the annular flow path. The piece-side coolant flow path is connected to a movable mold main body-side supply flow path of the movable mold main body and a movable mold main body-side discharge flow path of the movable mold main body and the coolant flows therein under negative pressure generated by a coolant circulation device, so the inside of the cavity can be cooled effectively.

摘要： An insert of a die for molding a speaker grille includes a forming member. The forming member defines a forming surface, from which a plurality of pins extend for forming apertures in a speaker grille. The forming surface defines a plurality of apertures disposed at spaced locations between the pins. The apertures are interconnected with a plurality vent channels communicating the apertures with the vent channels for venting air disposed in a die when melted polymer used to form the speaker grill is injected into the die. The forming member and the vent channels are formed as a monolithic construction.
