The present disclosure provides an injection molding apparatus including a first mold, a second mold configured to be relatively movable toward or away from the first mold and define a cavity for forming a molded body collectively with the first mold, a stripper provided between the first mold and the second mold and configured to separate the molded body from the first mold, a first cotter block provided on the stripper, and a second cotter block provided on the second mold, configured to be rollable relative to the first cotter block, and configured to align the second mold with the first mold collectively with the first cotter block, thereby obtaining an advantageous effect of reducing a defect rate related to the molded body and improving quality and productivity.

An injection mold assembly for manufacturing multiple-component articles includes opposed first and second mold halves mounted for movement in reciprocal directions along an axis of reciprocation between an open position and a closed position. A stripper plate is mounted between the first and second mold halves for reciprocation between a retracted position and an extended position when the first and second mold halves are in the open position thereof. Mold cores in one of a plurality of mold core assemblies are carried by the first mold half, and each mold core is mounted for rotation between a first position and a second position about an axis of rotation for the respective mold core assembly. The stripper plate accommodates rotation of the mold cores between the first and second positions while the stripper plate is in the retracted position.

A molding device for manufacturing a plastic hollow part by injection molding includes an injection nozzle and first and second molding stations. Each molding station has a first mold including two mold halves forming, respectively, first and second mold cavities, and a core having a first end, which can be at least partially located inside the first and second mold cavities. A first stripper can be arranged on the core in a passive position, spaced from the first end of the core at a first distance; in a molding position, spaced from the first end of the core at a second distance; and in a demolding position, spaced from the first end of the core at a third distance; wherein the first distance is greater than the second distance, and the second distance is greater than the third distance.

A process for making a multi-component hollow housing comprises injecting a first plastic material into a first mold cavity and causing it to solidify to form a first component, whereby the first plastic material shrinks lengthwise; injecting a second plastic material into a second mold cavity having the first component transferred thereto and causing the second plastic component to solidify to form a second component, the second component comprising a tolerance-elimination element that is longitudinally attached to the first component at one of the ends thereof, wherein a length of the shrunk first component is at least ten times greater than a length of the tolerance-elimination element, and wherein an absolute lengthwise shrinkage of the second plastic material forming the tolerance-elimination element is at least ten times smaller than the lengthwise shrinkage of the first plastic material; at least partially overmolding an intermediate part comprising the first and second component with a third plastic material in a third mold cavity, thereby forming the multi-component housing in which the tolerance-elimination element is at least partially overmolded by the third plastic material, and wherein the third plastic material forms at least a portion of an outer surface of the multi-component housing; and removing the multi-component housing from the core.

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.

A single component, multi-purpose injection molded plastic vial with a male luer lock fitting for use in multiple applications including filling, sealing, storage and delivery of various fluid products, in particular the dosage of medical and pharmaceutical fluid products.

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 component (100, 100) of a molding apparatus (110, 110) for producing hollow plastic items, in particular test tubes, syringes or tubular bodies, the component (100, 100) comprising: a first body (1,1) having a face (11) defining part of a separation surface of the molding apparatus (110, 110); a second body (2, 2), or stripper ring, inserted in the first body (1, 1), adapted to be crossed along an axis (X) by a core (3), and in particular to come into contact with the core (3); a plurality of elements (4, 4) inserted in the first body (1, 1), adapted to be displaced parallel to the axis (X); in which the second body (2, 2) has an outer surface (20) comprising a plurality of inclined portions (21, 21), in particular with respect to said axis (X); and in which each element (4, 4) of said plurality of elements (4, 4) has an outer surface comprising an inclined portion (41, 41), in particular with respect to said axis (X), which is in contact with a respective inclined portion (21, 21) of the second body (2, 2) so that the position of the second body (2, 2) can be adjusted by means of said plurality of elements (4, 4).
