Each cavity insert (440) includes a body (441) with a mounting face (441a) and a spigot (443) projecting from the mounting face (441a) and received in a respective seat (412) of the cavity plate (410) such that the mounting (441a) face abuts the front face (CVF) of the cavity plate (410). Each cavity insert (440) also includes a molding surface (448) along its length, at least two thirds of which extends beyond the cavity plate (410).

An apparatus for making a foam material body has a mold comprising at least two mold halves fittable together to form separate first and second mold cavities; a first sprue opening into the first mold cavity, and a second sprue opening into the second mold cavity. The mold parts can be moved between an open and a closed position. Foam can be injected into the first and second mold cavities through the respective sprues. A passage, for example, connects the sprue with the mold cavity. The first mold cavity and the second mold cavity are partitioned from one another in the closed position of the mold.

A net-shaped composite plenum housing body for a differential assembly having a pump is disclosed. The plenum housing body can include a low pressure inlet and a high pressure outlet configured to receive a control valve. The plenum housing body can also define a fluid inlet channel in fluid communication with the low pressure inlet via a first internal port and can be configured to be in fluid communication with an inlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also define a fluid outlet channel in fluid communication with the high pressure outlet via a second internal port and can be configured to be in fluid communication with an outlet side of the pump when the plenum housing body is assembled onto the differential assembly. The plenum housing body can also be formed as a net-shape fiber reinforced plastic material including chopped fibers, for example, chopped fiberglass fibers, and an epoxy resin.

A mold includes a core in which a molded product is formed, the core comprises a cored body and a sliding core on the core body, separable from the core body in a first direction with respect to the core body, and an ejector to press the sliding core in the first direction to separate the molded product formed in the core from the core. The ejector includes a driver positioned below the core and movable toward a lower surface of the core in the first direction or away from the lower surface of the core in a direction opposite to the first direction, and a rod movable in the first direction to press the sliding core to be separated from the driver or movable in the direction opposite to the first direction to couple the sliding core with the driver, and the rod is movable further in the first direction than the driver.

A preform mold (100) including a core plate (210), a cavity plate (410) and a plurality of mold stacks (MS) mounted between the core and cavity plates (210, 410). Each mold stack (MS) includes a core insert (250) mounted to the core plate (210), a cavity insert (440) mounted to the cavity plate (410) and split mold inserts (350) mounted between the core and cavity inserts (250, 440). The core inserts (250) are mounted to the core plate (210) by fasteners accessible from a rear side of the core plate (210). When the mold (100) is assembled, the core inserts (250) can be secured by the fasteners in a fixed condition in which they are immovable relative to the core plate (210). Also disclosed is a method of aligning the core inserts (250) by securing the core inserts (250) from a floating condition, in which they are able to slide relative to the core plate (210) along a sliding interface therebetween, to the fixed condition.

A core lifter having a lifter bar assembly formed of an elongate lifter bar with a replaceable lifter bar extension coupling carrying a coupling ball pivotably, rotatably, and translationally coupled to a lifter base fixed to an ejector plate of a plastic injection molding apparatus, the bar extension coupling removably coupled to the bar by a coupling joint configured to automatically self-align the bar relative to the base and mold in which the bar extends in a direction generally orthogonal to a lengthwise extent of the bar. Bar extension coupling is formed of an extension link having one end carrying the ball and an opposite end slidably coupled to an end of the bar by coupling joint. A preferred extension link is of breakaway sacrificial construction and slidably attached to the bar via a coupling joint that is a floating dovetail joint.

An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting 5 plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

When a preform is released at an early stage from an injection molding mold, the injection cooling time is shortened before releasing the preform at an early stage from the injection molding mold to shorten the cycle time of molding the preform while the preform trunk portion is prevented from being deformed. A trunk support portion is formed on an outer end inner surface portion of a support ring molding portion in the lip mold and is configured to support a preform trunk portion at a time of releasing the preform in a non-contact manner.

A mold apparatus for producing a molded article by injection molding includes (a) a base plate for mounting to a platen of an injection molding machine; and (b) a core plate movably coupled to the base plate and axially translatable relative to the base plate between a plate advanced position and a plate retracted position. A method of resetting the core plate includes energizing a mechanical actuator in a retraction direction to exert a retraction force against the core plate and axially translate the core plate relative to a base plate from the plate advanced (molded part ejection) position to a plate retracted (mold injection) position; and then, prior to applying clamping tonnage, relieving the retraction force to axially unload the mechanical actuator, wherein the actuator is isolated from axial force exerted across the mold during application of the clamping tonnage.
