摘要： A guide for a manifold plug of an injection molding apparatus comprises a guide body projecting from an inner wall of the manifold plug diametrically opposing an inlet of a manifold plug channel formed in the manifold plug. The inlet is aligned with a manifold channel of a manifold. The outlet of the manifold plug channel is aligned with a nozzle channel of a nozzle. The inlet is at an angle to the outlet. A guide surface is provided on the guide body for abutting a downstream portion of a valve pin extending into the manifold plug channel. The guide also facilitates flow of a melt stream of moldable material through the manifold plug channel.

摘要： A valve-type nozzle (10) is provided for use in hot runner systems through which a plastic material melt is fed under high pressure to a separable and coolable tool having at least one mold cavity (K) for injection-molded items. The nozzle is heatable and comprises at least one needle valve (20) supported by sliding guides (28, 38), the arrangement being such that the melt, which is fed trough a material pipe (14), passes around at least a lower section (22) of the needle valve (20). The nozzle (10) further comprises, in an antechamber (30) upstream of the mold cavity (K), at least one outlet (18) adapted to receive a closely fitting needle end (24). The needle valve (20) includes in its lower section (22), upstream of the needle end, a pressure-relief arrangement that is in direct flow-connection with the antechamber (30). The pressure-relief arrangement comprises, in a guide piece (40), at least one branch-off bore (32; 34) that runs radially at an angle of 90° to the longitudinal direction (L) of the needle valve (10).

摘要： Mold bushings or nozzles for gas-assisted injection molding processes are disclosed. The devices include movable shut-off mechanisms which selectively facilitate or prevent the passage of molten plastic material into mold cavities. One or more apertures, such as holes, openings, channels, slits, slots, and the like, are provided at or adjacent the end of the pin members or at the end of the devices. The apertures are thin or small and have dimensions which will allow the passage of gas and at the same time prevent the plastic material from plugging or clogging them.

The apparatus includes a mold for forming the substantially flat article, which mold includes an inlet gate for allowing molten plastic material to flow into a cavity space defined by the mold. The apparatus further includes a source of molten plastic material, a passageway communicating with the inlet gate and the source of molten plastic material, and a blade or pin for pushing residual plastic material in the passageway into the cavity space formed so as to form a side edge for the substantially flat article having substantially no gate vestige. A method for manufacturing the substantially flat article is also described.

摘要： Improved method and apparatus for injection molding particularly useful with multiple hot runner valve gates to fill a single large mold cavity. A hot runner injection nozzle is provided having a gate through which melt is injected into a mold cavity, and a valve stem is movable on the injection nozzle between an open position permitting flow of melt through the gate and a closed position blocking the flow of melt through the gate. The valve stem is movable to at least one position between the open and closed positions restricting the flow of melt through the valve gate.

摘要： A valve pin actuator is disclosed that includes a cylinder mounted to the clamping plate, a piston slidably mounted in the cylinder, and a valve pin assembly carried by the piston. A hydraulic or pneumatic circuit is provided for controlling the movement of the piston, and in turn translation of the valve pin between the seated and unseated positions. The valve pin assembly includes a first part removably secured to the piston so as to translate therewith, and a second part for receiving the valve pin and secured to said manifold. The actuator assembly enables removal of the clamping plate without removal of the valve pin assembly, and also adjusting of the valve pin without removal of the clamping plate. The assembly further provides a clearance between the piston and valve pin assembly, to accommodate expansion and movement of the manifold that would otherwise cause a side load to be exerted on the valve pin.
