摘要： An injection gate of a mold cavity comprises an elongate valve rod which passes axially through a flow channel for molten plastic material and is guided in an extension of a thin-walled steel cylinder open at its opposite end toward an adjoining manifold plate. The rod extremity remote from the gate is secured to a tubular neck of a piston inside the cylinder whose stroke length is a fraction of the axial height of the cylinder's interior, a clearance around this neck providing space for drooling plastic while the length of the neck and of the peripheral cylinder wall serves for thermally insulating the manifold plate from the flow channel. The piston has a head sliding within an internal annular shoulder of the cylinder wall, proximal to the manifold plate, which is traversed by axially oriented bores communicating with the aforementioned clearance whereby pressure fluid such as compressed air can be selectively admitted from conduits in the manifold plate to either side of the piston head for reciprocating same together with the valve rod. A plurality of such valve-control pistons can be connected to these conduits in parallel for simultaneous actuation by the air pressure applied thereto.

摘要： An injection molding machine includes a base, a stationary platen fixed to the base for holding a first mold section, and a moving platen for holding a second mold section. The moving platen is slidably supported on a platen slide surface fixed to the base and moveable along a machine axis between a mold closed position, in which the moving platen is drawn towards the stationary platen, and a maximum daylight position, in which the moveable platen is spaced axially apart from the stationary platen by a platen opening. The machine further includes a carriage support structure slidably supporting a stack mold carriage for holding a mold center section. The stack mold carriage is translatable parallel to the machine axis between a carriage advanced position and a carriage retracted position spaced axially apart from the carriage advanced position by a carriage stroke length. The carriage support structure includes a pair of beams removably fixed relative to the base, the beams extending parallel to the machine axis and spaced apart from each other by a lateral spacing, each beam having a beam length that is less than the platen opening and greater than the carriage stroke length.

摘要： The present invention relates to stack mold carriers in an injection molding machine with a rotating turret. Services to the rotating turret are provided by a rotary union attached to the translating mold carrier at the turret's axis of rotation. Hence, services such as oil, water, air and electrical power are provided to the rotating turret thereby allowing the turret to rotate in either direction. The rotating turret is attached to linkages which open and closed the molds through connection to a moving and a stationary platen which interface with the rotating turret to form molded articles therein.

摘要： An energy efficient drive system is provided for use on typical injection molding machines whereby a single electric motor drives both the extruder screw and a hydraulic motor that continuously charges a hydraulic accumulator during the extrusion process. During the injection cycle, the charge in the accumulator is directed to stroke the extruder screw and inject melt into the mold cavities. Another embodiment utilizes a similar arrangement on the clamp mechanism of the injection molding machine whereby the charge in the accumulator is directed to hold the mold closed during the injection cycle.

摘要： A valve gating apparatus and method for injection molding includes at least one shutter disposed between the gate and the cavity melt channel into a mold cavity. The shutter is moved laterally, between a closed position wherein flow of melt from the nozzle into the cavity is inhibited, and an open position wherein flow of melt into the cavity is unimpeded by the shutter. Intermediate these two positions, the shutter can be employed to reduce the cross sectional area of the gate to throttle the gate. Embodiments are disclosed wherein one shutter or pairs of shutters are employed to gate the gate. Further, when pairs of shutters are employed, the shutters can abut each other in the close position or can overlie each other. This novel design prevents generation of waste material and eliminates the need to have devices for removing cold plugs.
