摘要： A hot sprue bushing is provided for transporting plasticized material from an injection nozzle to a mold cavity while controlling the temperature of the plasticized material. This hot sprue bushing comprises an elongate body having a head, a stem and a distal end portion, and a through passage extending therethrough from end to end through the head, stem and distal end portion of the body for transporting plasticized material through the hot sprue bushing from the heat to the distal end portion thereof. The distal end portion of the body bears a first engaging device, and the head of the body is of greater cross-section than the stem so that the head provides a first abutment surface extending outwardly of the stem. An electrically powered heater is wrapped around the stem of the head in heating conducting relationship therewith. A sleeve surrounds the electrically powered heater; and a tip member has a second engaging device engaged with the first engaging device on the distal end portion of the body, the tip member having a second abutment surface engaged with one end of the sleeve so as to urge the opposed end of the sleeve into engagement with the first abutment surface on the head. The tip member permits egress of plasticized material from the through passage in the body.

摘要： A side gate nozzle assembly for a hot runner apparatus comprises a disc shaped base body, a probe member, a sealing insulator, and a shape memory alloy washer. The probe member with a probe channel extends from the base body. A molten molding material is received through a melt channel of the nozzle body, and allowed to pass through the probe channel to be transferred to a cavity of a cavity member. The shape memory alloy washer is positioned between the base body and the sealing insulator. The shape memory alloy washer distorts linearly to push the sealing insulator and the probe member according to change in temperature due to transfer of the molten molding material from the melt channel to the cavity member via the probe channel. The distorted shape memory alloy washer prevents leakage of the molten molding material from the melt channel, and the probe channel.

摘要： A highly reliable hot sprue bushing with an interchangeable tip having multiple edge gates for use in controlling the temperature of plasticized material while it flows from the injection nozzle to the gates of a multiple cavity mold. Advantageously, the hot sprue bushing is adjustable in length so that it can be used with a full range of standard or custom mold plate thicknesses or other required lengths and the interchangeable tip does not require separate heating and temperature control.

摘要： An in-line single nozzle valve gate apparatus for injection molding comprises upper and lower matable annular cylinder bodies that house an annular dual sided piston having opposed pressure bearing upper and lower surfaces. The piston has a cross beam to which a valve gate pin is attached for movement therewith. The valve gate pin passes through a sprue bushing flow path to selectively open and close a part cavity gate. An interface is provided to receive molten plastic from the injection machine nozzle and pass it into the sprue bushing flow path. The cylinder bodies reside largely outside of the mold plate architecture to lessen thermal damage too piston seals.
