    摘要： A sprue bush that is attached to a mold used to mold synthetic resin includes: a sprue bush main body (10) that has a flow passage, through which synthetic resin injected from an injection molding nozzle flows, and a recessed portion (13) formed in a surface of the sprue bush main body on a synthetic resin injection port side thereof; and a bush component (20) that is embedded in the recessed portion (13), the bush component (20) including: a nozzle contact surface (21) that is contacted by the injection molding nozzle; a through hole (22) that extends from an opening in the nozzle contact surface (21) and communicates with the flow passage in the sprue bush main body so as to form the flow passage for the synthetic resin; and a plurality of ribs (23) that extend radially outward from an inner peripheral surface of the through hole.

    摘要： A nozzle retention arrangement is provided for an injection molding manifold system, such as a hot runner manifold system. The nozzle retention arrangement couples an injection nozzle to a distribution manifold in a manner that locates the nozzle in its final operating position and applies an initial assembly load to retain the nozzle in position on the manifold to facilitate installation of a manifold system into a manifold plate. The nozzle retention arrangement may provide a compliant load application feature to limit sealing surface pressure between the nozzle and the manifold to prevent surface damage between the components, while also accommodating thermal expansion of the heated components during operation of the system. The nozzle retention arrangement may also provide a load control feature to prevent the machining quality of the nozzle bore in the manifold plate from determining the sealing load between the nozzle and the manifold.

    摘要： Disclosed is a hot runner system including a thermal expansion compensation device. The hot runner system including a thermal expansion compensation device, according to the present invention, compensates for the dislocation of a joint between a manifold and a resin due to thermal expansion of the manifold heated by a heating wire at a high temperature so as to prevent the leakage of the resin resulting from a gap formed therebetween and to appropriately maintain the flowability of the resin. Thus, high reliability can be secured according to the arrangement of the simplified structure between the manifold and nozzles.

    摘要： A ring valve gate mold device includes: a stationary mold and a movable mold that are disposed so as to be allowed to be joined together and separated from each other; an annular cavity used to form an annular product, the cavity being formed in a mating face that is an upper face of the movable mold; a supply passage through which molten resin is supplied via a circular gate connected to the entire circumference of the annular cavity; and a valve body that opens and closes the circular gate of the supply passage. The valve body is a tubular sleeve body that moves in the axial direction of the ring valve gate mold device to open and close the circular gate. The sleeve body is disposed at a position radially outward of the supply passage connected to the gate.

    摘要： In a method for producing a shaped part, a closing movement is executed by displacing at least one of two mold halves of a high-pressure resin transfer tool from an open position into a pre-closure position of the resin transfer tool such that an opening gap between the mold halves is sealed air-tight by a sealing device of the resin transfer tool to thereby enclose a cavity. The cavity is evacuated by pumping air out of the cavity, and the closing movement is continued by displacing at least one of the two mold halves from the pre-closure position into a final closure position, in which the mold halves are sealed against one another by a further sealing device to allow filling of the cavity, enclosed by the two mold halves, with resin without leakage during a high-pressure resin transfer molding process.
