A mold replacement method that can contribute to simplification of unloading a fixed mold and a movable mold when the fixed mold and the movable mold are replaced. A mold replacement method includes coupling a fixed mold to a movable mold in a vertically divided molding machine, releasing a coupled state between the movable mold and a movable mold equipment base, rotating the fixed mold and the movable mold by a rotating mechanism for rotating a fixed mold equipment base, and disposing the movable mold above the fixed mold, releasing the coupled state between the fixed mold and the fixed mold equipment base, and unloading the fixed mold and movable mold from a fixed mold equipment base while a protrusion protruding outward from the movable mold is being supported by a fork of a lifting and lowering device.

An injection molding apparatus for producing a plastics molding comprising a first component, a second component, and a third component comprises a first mold plate having at least 3 first mold nests, and a second mold plate having at least 3 second mold nests. In the closed state, the mold plates cooperate in the production of the plastics mold. In the opened state, the second mold plate is rotatable relative to the first mold plate. The at least 3 second mold nests comprise, in a case A), at least two second mold nests for injection molding the first component, and at least one second mold nest for injection molding the third component, or, in a case B), at least two second mold nests for injection molding the second component, and at least one second mold nest for injection molding the first component.

An assembling apparatus that has a mold in which a second unit opposes a first unit and that is configured to assemble an assembled product from a plurality of parts. The first unit includes first, second, and third movable portions, which comprise, respectively, a plurality of first forming portions, a plurality of second forming portions, and a plurality of third forming. The second unit comprises a fourth movable portion, a fourth forming portion, a fifth forming portion, a sixth forming portion, and a plurality of assembling portions. The fourth movable portion is configured to move so as to switch at least one assembling portion opposed to at least one first forming portion, at least one other assembling portion opposed to the at least one second forming portion, and at least one remaining assembling portion opposed to at least one third forming portion.

An assembly appliance for mould tool parts of an injection moulding tool is disclosed, the assembly appliance including an assembly plate configured for insertion into an injection moulding machine and including a tool carrier for receiving first mould tool parts to be assembled; and an assembly frame having a guide system for a translatory displacement of the assembly plate along a longitudinal extension of the assembly frame, and a support device for stationary support of a second mould tool part which corresponds to at least one of the first mould tool parts.

In order to increase the degree of automation, an overmolding device for processing profiles, having a turntable with a worktable device that is movable in rotation about an axis of rotation in a rotation plane and has at least two processing areas, is proposed, wherein the processing areas each comprise a central plate, wherein the central plate is attached to and/or mounted on the worktable via a central-plate receptacle, wherein the turntable comprises an upper and a lower mold, which are decoupled from the rotation of the worktable device and which are arranged opposite one another with regard to the rotation plane, and wherein the upper and lower mold are movable such that, together with the central plate, they form a mold receiving the profile, and the central-plate receptacle (5) forms the fixed closing side and the upper and lower molds form the movable closing side.

A method for producing components or profiles from at least one solidifiable plastic compound in an injection moulding facility, said method comprising stationary mould components and mould components which are movable with respect thereto. The method includes injection of solidifiable plastic compound into a channel formed in the movable mould components and, from there, via connections either in portions into one or more mould cavities. The channel is enclosed by at least one stationary, temperature-controlled mould component. A continuous channel compound strand is formed with attachment compound strands, which is transported away from the injection point with increasing cooling and solidification and increasing length, together with the filled mould cavities and mould cavity portions. The channel compound strand, together with the connection mass strands, after its solidification and after opening the mould cavity or the mould cavities is separated from the component(s), and the component or the components is/are ejected.

The present invention achieves cost reduction by simplifying the manufacturing process for a film-formed molded product provided with a metal coating film capable of transmitting electromagnetic waves therethrough. This method for manufacturing a film-formed molded product which includes a molded product and a metal coating film covering the molded product comprises: forming the molded product between a movable mold and a fixed mold; and then forming the metal coating film which covers the molded product by a film-forming part of a second mold without taking the molded product out from between the movable mold and the fixed mold. The metal coating film is capable of transmitting electromagnetic waves therethrough as a result of generation of cracks after being formed.

The disclosure provides an injection molding apparatus, including a mold unit, an injecting unit, and a counter pressure unit. The mold unit is adapted to provide a first cavity and a second cavity. The injecting unit is adapted to inject a first material into the first cavity to form a first molded object. The second cavity is adapted to accommodate the first molded object. The injecting unit is adapted to inject a second material into the second cavity to form a second molded object, such that the first molded object and the second molded object in the second cavity are combined. The second material is a foaming material. And the counter pressure unit is adapted to provide gas into the second cavity to increase the pressure in the second cavity.

A method for manufacturing a glass with a stem or with a base made of a plastic material, the glass including a receiving portion mounted over a base or over a stem, the method being implemented by a rotary tooling comprising a plurality of workstations and at least one mold wherein the method includes the following steps: a) forming of the receiving portion of the glass on at least one first workstation called injection station; b) overmolding of the stem or of the base over the receiving portion, in order to form a glass with a stem or with a base, the overmolding being carried out on at least one other workstation called overmolding station; c) ejection of the glass thus formed on the overmolding station or on another workstation called ejection station.

An assembly appliance for mould tool parts of an injection moulding tool is disclosed, the assembly appliance including an assembly plate configured for insertion into an injection moulding machine and including a tool carrier for receiving first mould tool parts to be assembled; and an assembly frame having a guide system for a translatory displacement of the assembly plate along a longitudinal extension of the assembly frame, and a support device for stationary support of a second mould tool part which corresponds to at least one of the first mould tool parts.
