INJECTION MOLD WITH CENTERING DEVICE
An injection mold with a centering device includes a die-holding plate with a cavity-forming die unit, a core-holding plate with a core unit, and a stripping plate between the core-holding and die-holding plates. The centering device has a insert and a mount with a clearance, which is rotationally symmetrical about a center axis and is for receiving the insert. The insert has an opening for receiving the core unit and the insert and the clearance of the mount are insertable in a torsion-free manner in the clearance of the mount in at least three positions rotatable about a center axis of the insert, and the center axis of the clearance and the center axis of the insert overlie one another. A center axis of the opening of the insert is arranged eccentrically in relation to the center axis of the insert by an offset. The centering unit is arranged in the stripping plate.
Molding apparatus and method of controlling same
There is disclosed a method (400) of ejecting a molded article (310, 312) from an injection mold (100). The method (400) comprises: during a second portion of the mold opening cycle of the injection mold (100), the second portion occurring later in time relative to a first portion of the mold opening cycle of the injection mold (100): controlling velocity of at least one of: (i) the moveable mold half (102, 502) relative to the stationary mold half (104, 504), (ii) the ejector (230) relative to the moveable mold half (102, 502); and (iii) an ejector actuator linked to the core insert (112, 114, 512, 514); and (iv) a stripper actuator that is linked to the stripper sleeve (116, 516); the controlling executed such that the molded article (310, 312, 506) is ejected from the molding component with a substantially zero departure-velocity along the first axis of operation.
A PLUMBING CONNECTOR
A pipe connector having a body with a tubular part to seal with a pipe. The tubular part has an outer face with a projecting feature to seal with the pipe. A collet is fixed to the body and spaced from the tubular part to form a cavity for the pipe. A locking cap is captive on and screwed onto collet to deflect the collet onto the pipe and the pipe onto the tubular part to seal between the body and the pipe. The collet has through slots at its distal end allowing the pipe to be visible when the connector is locked and unlocked. The inner diameter at an open end of the collet is optionally greater than the inner diameter of the distal part that receives the pipe. A method of forming the connector is also disclosed.
Molds, mold assemblies and stack components
An injection mold (100) including a core plate assembly (200), a cavity plate assembly (400) and a stripper plate assembly (300) arranged between the core and cavity plate assemblies (200, 400). The mold (100) includes a plurality of mold stacks (MS) with a molding configuration, in which the mold stacks (MS) are closed to define molding cavities. A gap (G) is provided between the core plate (210) and the stripper plate (310) when the mold (100) is in the molding configuration, such that a clamping load (CL) applied to urge the core plate (210) toward the cavity plate (410) is directed substantially entirely through the mold stacks (MS).

MOLDING SYSTEM WITH MOVABLE SPLIT MOLD INSERTS
Disclosed herein, amongst other things, is, a stripper assembly operable to eject a molded article from a mold that includes slides that are movable laterally relative to each, a first split mold insert inter-connected to a first slide and a second split mold insert inter-connected to a second slide. The system being operable such that when the first and second slides are in the closed position, the first and second split mold inserts form at least a portion of the molding cavity; the system being operable such that such during operation of the injection molding system, the first split mold insert is movable relative to the respective first slide and the second split mold insert being movable relative to the second slide.
DIALYZER MANUFACTURING TOOL
A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.
Mold stack for injection molding machine
A mold stack for a mold comprises a mold core configured for reception in a mold cavity plate with an outer molding surface. The mold core comprises an inner core with a first tapered guide surface and an outer core with a second tapered guide surface. The inner core is received through a passage in the outer core. A spacer slidably supports the outer core on the inner core. The outer core is movable relative to the inner core between a molding position in which the inner and outer cores define a mold cavity with the outer molding surface, and an open position in which the outer core is extended relative to the inner core. In the molding position, the first and second tapered guide surfaces engage one another to align the inner and outer cores.
Injection moulding tool with adjustable core centring device
An injection moulding tool with at least one cavity for producing thin-walled, container-like injection-moulded products, in particular cups, tubes, tube heads, vials, bottle blanks or syringes. The injection moulding tool comprises a die holding plate, which has at least one cavity-forming die; a core holding plate, which has at least one core unit with a cavity-forming core; at least one stripping ring for stripping the injection-moulded product off the at least one core, with the at least one stripping ring arranged between the core holding plate and the die holding plate; and at least one adjustable core centring device for the fine alignment of the at least one core in the at least one die. The stripping ring is held in a floating manner in a stripping plate, which is arranged between the die holding plate and the core holding plate; and the at least one adjustable core centring device is arranged between the core unit and the core holding plate.
