摘要:
The present invention provides a molding die and a control method thereof aimed at shortening cycle time from heating to cooling of a molding cavity of the die with a simple and inexpensive configuration. In a molding die equipped with a molding cavity to mold a base material, a magnetic die material is used for the molding cavity, cooling means to feed a refrigerant is installed inside the molding cavity along a molding face and heating means by high-frequency induction is installed around the cooling means, and the molding cavity is alternately heated and cooled repeatedly by the heating means and the cooling means when the base material is molded with the molding cavity. Here, the cooling means includes a tubular body installed in the molding cavity, feeds a refrigerant when the molding cavity is cooled, and is in a hollow state of not containing the refrigerant when the molding cavity is heated.

Mold assemblies for compression molding of footwear components include molds, heating elements, conductor plates, insulating layers and carrier trays. An upper mold assembly is placed into a fixture attached to an upper press platen. A lower mold assembly slides into and out of a fixture attached to a lower press platen. Heating elements within the mold assemblies connect to electrical contacts in the fixtures when the mold assemblies are installed in the fixtures, thereby providing electrical power to the heating elements and heating the molds. A conveyor is positioned to receive a mold assembly from (or transfer a mold assembly to) the lower press platen fixture when the lower platen is in a lowered position.

A green tire disposed on a toroidal support is introduced into a vulcanisation mold. The mold is closed through axial approaching of a pair of sidewall plates acting against the sidewalls of the tire. Circumferential sectors set to operate against the tire tread band are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tire against the toroidal support. Subsequently, the sectors are centripetally approached for penetration into the tread band concurrently with a step of full molding and vulcanisation of the tire carried out through admission of steam under pressure into the tire itself.

A heater cartridge and a molding apparatus using the heater cartridge are provided. The molding apparatus includes a mold comprising at least one cartridge channel and a heater cartridge inserted to the cartridge channel, the heater cartridge comprising a main body casing, a plurality of heating sectors dividing an inside of the main body casing, and a heating part provided to at least one of the heating sectors to heat a predetermined area of the mold. The heater cartridge and molding apparatus having same provide uniform heating to enhance thermal efficiency and the quality of a product.

A method for making a garment having a lofted assembly having an inner laminated support fabric and an outer panel and the garment produced are provided. The method includes the steps of positioning a support fabric on a lofted material; laminating the support fabric to the lofted material to form a lofted assembly; positioning the lofted assembly in a molding apparatus having at least a first mold and a second mold, closing together the first mold and the second mold thereby sandwiching the lofted assembly therebetween and while maintaining a uniform preset gap between said first mold and the second mold so that the inherent loft characteristics of the lofted assembly are substantially preserved. Then the outer panel is stitched to an outer side of said lofted assembly.

A green tyre disposed on a toroidal support is introduced into a vulcanisation mould. The mould is closed through axial approaching of a pair of half shells acting against the sidewalls and the tread band of the tyre. Circumferential sectors set to operate against the tyre tread band are maintained spaced apart from the tread band itself during admission of a working fluid designed to press the tyre against the toroidal support. Subsequently the sectors are centripetally approached to cause penetration of forming ridges movable in through slits into the tread band, concurrently with a step of full moulding and vulcanisation of the tyre carried out through admission of steam under pressure into the tyre itself.

An temperature control apparatus includes a temperature detecting element (50), a control circuit (60), and a thermoelectric unit (70). The temperature detecting element contacts to a first surface (82) of a predetermined target (800). The control circuit is electrically connected to the temperature detecting element. The thermoelectric unit is electrically connected to the control circuit, and contacts a second surface of the predetermined target. The temperature detecting element detects a temperature signal. The temperature signal is input into the control circuit. The control circuit changes the temperature signal into an electrical current signal, and the electrical current signal drives the thermoelectric unit to control the temperature of the predetermined target.

A method of transcribing a shape of a surface of a stamper on a transcription surface of a transcription object by pressing the stamper on the transcription object, which comprises steps of: having one of the stamper and the transcription object positioned opposite a plate surface and the other of the stamper and the transcription object placed on one surface of a pressure plate; and having the one of the stamper and the transcription object pressed onto the plate surface by applying a fluid on the other surface of the pressure plate, wherein an area of the one surface of the pressure plate is larger than a contact area in which the other of the stamper and the transcription object is in contact with the pressure plate.
