摘要： PROBLEM TO BE SOLVED: To provide an injection molding apparatus comprising a mold block, a nozzle, a gating system and a slug heater. SOLUTION: The mold block 16 forms a mold cavity 32 with a mold cavity inlet. The gating system 18 comprises a valve pin 44 and an actuator 46. The valve pin is freely movable between an opening position where a melted body can flow into a mold cavity and a closed position where the valve pin closes a flow passage for the melted body so that the melted body does not flow into the mold cavity. The actuator moves the valve pin between the opening position and the closed position. When the valve pin exists at the closed position, a cooling system is provided on at least one of the mold block and the valve pin to selectively solidifying the melted body to form a slug just at the upstream of the valve pin. When the valve pin is separated from the slug, the slug closes the melted body flow passage to substantially stop leakage of the melted body through the slug. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an improved gate device for an injection molding having a large aperture. SOLUTION: A valve pin assembly M for an injection molding apparatus comprises a valve pin 1 capable of moving up and down in a nozzle 7 to open and close a ring gate. An annular passage 12 is formed through the nozzle and is unobstructed without restriction at all points up to and through the ring gate, thereby permitting melt to flow freely to the gate and, according to the position of the valve pin, into the mold cavity. The valve pin has a head with a diameter larger than the valve pin shaft for selectively closing the gate. The ring gate channel diameter is larger than the melt channel diameter to permit products with large aperture therein to be formed.

摘要： PROBLEM TO BE SOLVED: To provide an injection molding system for performing the dynamic control of the amount of a plastic injected according to an injection cycle.
SOLUTION: This injection molding system is equipped with a manifold and a valve gate type hot runner nozzle. A gate mechanism is equipped with a valve drive shaft and a molding gate opening part is opened when a valve stem is present at a first position so that a melt flows. The molding gate opening part is closed when the valve stem is present at a second position so as to suppress the flow of the melt. A flow rate control shaft is positioned in a molten fluid material and located in the melting route of the nozzle to become the same axis as the valve stem or located in the melting route of the manifold. The flow rate control shaft has a head part having the shape fitted to the shape of the melting route in a flow rate control surface and moved up and down by a drive mechanism independently of the movement of the valve stem so as to suppress or open the flow of the molten flow material.

摘要： PROBLEM TO BE SOLVED: To provide an injection molding system installing a plurality of nozzles in which a means for switch control of valves is set forth.
SOLUTION: The system installs many valve switching type nozzles, a flow passed through each valve gate is controlled by a valve pin operated independently, and each valve pin is controlled independently by another operating unit. The operating units are set forth in a stack form in order to realize the tight arrangement among the valve pins and the valve pins controlled by the operating units at the upper site are penetrated into the operating units at the lower site, and the valve pins at the lower site are offset from the center of the operating units at the upper site, whereby a flow passing through from the operating units at the upper site to the operating units at the lower site can be secured without any interruption.

摘要： In a manifold, the valve pin has a sealing surface proximate its bottom end, which surface is engageable with a gate sealing surface to inhibit melt flow into the cavity. A first guidance and alignment structure is connected to the valve pin, and a second structure to the mould block upstream from the gate. Both structures include first and second guide surfaces of a diameter decreasing gradually in a downstream direction and first and second cylindrical alignment surfaces. The first guide surface is positioned immediately downstream from the first alignment surface, the second guide surface immediately upstreams from the second alignment surface. The second guide surface is positioned to complete alignment of the valve pin with the gate prior to contact between valve pin and gate. Further, it is positioned to engage the first alignment surface to maintain the valve pin in alignment with the gate during its movement towards the gate.
