This invention relates to a handling device for the removal of plastic injection-molded parts, designed as pipette tips, medical reaction vessels or contact-lens molds, from an injection mold tool (11), having a removal gripper having a plurality of receiving positions (1-32; 104, 105) for receiving one injection-molded part from each of the cavities in each instance.

A method includes a first molding process and a second molding process performed repeatedly. The first molding process includes injecting resin into a first pair of molds, in which a first pair of divided pieces is formed and which is fitted together without an inner mold, to couple the first pair of divided pieces to form a first hollow article at an injection station. The second molding process includes (i) injecting resin into a third pair of molds, which is fitted together with one inner mold interposed therebetween, to mold a third pair of divided pieces at the injection station, (ii) taking out the first hollow article from the first pair of molds at a removing station, and (iii) removing another inner mold from a second pair of molds while leaving a second pair of divided pieces between the second pair of molds at the setup station.

A molding device for producing thermoplastic articles and its method of use, wherein the molding device comprises a rigid bottom plate, a rigid top plate adapted to be removably coupled to the said bottom plate, a 3D-printed die or insert in the shape of half of the said article removably inserted into a CNC milled mold cavity. The molten thermoplastic material is injected in to the molding device through an injection port to form the thermoplastic in the shape of 3D-printed die or insert, wherein the thermoplastic article is a fishing lure.

A molding method of a liquid elastomer can reduce an amount of disposal of a molding material, and can prevent a metal mold from being enlarged in size on a plane when a plurality of molded articles are simultaneously molded by using the metal mold, thereby achieving a good manufacturing efficiency. The molding method of the liquid elastomer molds a molded article constructed by a liquid elastomer by using a metal mold, the metal mold is a metal mold for an injection molding, a plurality of product cavity spaces are provided side by side in a mold clamping and mold opening direction of the metal mold, and a plurality of molded articles are simultaneously molded by using the metal mold. The metal mold has a sprue, runners and gates which are communicated with a plurality of product cavity spaces. The runners have orthogonal runner portions and parallel runner portions.

A mold injection tool includes a first mold plate having first and second columns of mold cavities, each of the cavities and a first cull block arranged between the first and second columns. A plurality of first channel sections is formed between an adjacent pair of mold cavities. Each of the first channel sections are configured to guide liquefied molding material from the first cull block into the adjacent pair of mold cavities in the first and second columns. The mold injection tool further includes a second mold plate having similarly configured mold cavities, cull block, and channel section. Adjacent ones of the first and second channel sections form a contained chamber when the first and second mold plates are pressed together. The mold plates are configured to inject liquefied molding material through an entrance that is in open communication with each contained chamber.

It is described a method and an apparatus for injection co-mould and assemble plastic material objects having a first part provided with a hinge pin, and a second part provided with an annular element suitable to be coupled in an articulated manner. The apparatus includes a mould having separated moulding impressions for the two parts to be moulded; a first moulding pin element defining the pin impression and a second moulding pin element defining the annular element impression are provided. The apparatus includes cooling means; particularly the first pin element is internally provided with a channel and a tubular element, being coaxially arranged and defining a cooling gap. A cooling fluid flows through the tubular element and the gap. Cams are provided which axially move the pin elements to cause the automatic assembly of the object during the mould opening and then to allow extracting the moulded object.
