The first hinge end may comprise a first hinge slot, and the second hinge end may comprise a second hinge slot, both hinge slots located on inner surfaces of their respective mold blanks. The mold assembly may comprise a first hinge bracket detachably coupled to the first hinge slot and a second hinge bracket detachably coupled to the second hinge slot. A hinge pin may be detachably coupled to the first hinge bracket and the second hinge bracket, and the first mold blank and the second mold blank may be configured to rotate about the hinge pin.

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.

Provided is a method of manufacturing a resin retainer having two annular sections. A fixed-side cavity forming mold has a first axial mold surface that is in contact with an axial end surface of a first annular section of the annular sections of a resin retainer having two annular sections, and a first protruding portion protruding from the first axial mold surface. A movable-side cavity forming mold has a second axial mold surface that is in contact with an axial end surface of a second annular section of the annular sections of the resin retainer, and a second protruding portion protruding from the second axial mold surface. A slide core sliding step is performed in which slide cores are slid toward an outer diameter and pocket-forming protruding portions of the slide cores are extracted from a pocket of the retainer, and then a mold opening step is performed in which the movable-side cavity forming mold is opened relative to the fixed-side cavity forming mold.

Provided is a molding system for molding a thermoplastic article. The molding system comprises a first mold half and a second mold half. The first and second mold halves together define a plurality of molding cavities in a first closed position. The plurality of cavities serve to mold a corresponding plurality of article components in a first molding stage. Subsequent the first molding stage, the first mold half is displaceable relative to the second mold half to align the plurality of article components formed during the first molding stage. During a second molding stage, the first and second mold halves are closed to a second closed position, to engage and bond together the plurality of article components into a finished thermoplastic article.

A mold for an injection molding system including an injection molding machine, a conveying apparatus configured to convey a mold to a molding operation position in the injection molding machine, and a driving unit configured to provide power for moving the mold, the mold including a fixed mold, a movable mold, and a clamping plate fixed to the fixed mold, wherein the improvement to the mold includes a first attachment area for transmitting the power from the driving unit to the mold is provided on the clamping plate and in an extending portion that extends downward from the fixed mold or on the clamping plate and in a protruding portion that protrudes from the fixed mold in a conveyance direction of the mold and located lower than a middle of the clamping plate.

Manufacturing a molded part using one injection molding machine while changing between multiple molds includes performing, at a molding operation position in the injection molding machine, clamping, injection, and dwelling of a mold, conveying the mold from the molding operation position and performing a process of cooling the mold at a position different from the molding operation position, conveying the mold to the molding operation position, opening the mold, and ejecting a molded part from the mold, wherein, before performing the first step for a first mold, a molded part previously ejected from a second mold is placed into the first mold that has been opened.

A method for manufacturing a molded part with an injection molding machine and a conveying apparatus while changing between multiple molds, the method including conveying a first mold to a molding operation position in the injection molding machine, securing the first mold at the molding operation position with a platen, fixing the platen to the first mold, opening the first mold, ejecting a molded part from the first mold, placing the first mold into a state where the first mold is slightly opened, injecting a molding material into the first mold, applying pressure to the first mold by closing the slight opening of the first mold, releasing the platen from the first mold, conveying the first mold from the molding operation position to the conveying apparatus, and cooling the first mold on the conveying apparatus.

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.
