A method for producing a component assembly for a motor vehicle, wherein the component assembly has a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the at least one functional component is injection-molded to the base body during the production of the component assembly and the component assembly is produced using a gas external pressure process. A component assembly for a motor vehicle is also provided, having a base body for an instrument panel of the motor vehicle and at least one functional component, wherein the base body is produced as an integral injection-molded part together with the at least one functional component using an external gas pressure process. Also, a motor vehicle having a component assembly is provided.

A cooling system of an injection mold comprises an air cooling pathway formed in a mold core and having an inlet and an outlet, a vortex tube having a cold air output port, a hot air output port, and a compressed air input port, and a compressed air supply device in communication with the compressed air input port and configured to supply a compressed air to the vortex tube. The vortex tube separates the compressed air into a cold air with a temperature lower than that of the compressed air and a hot air with a temperature higher than that of the compressed air. The cold air is output from the cold air output port. The hot air is output from the hot air output port. The cold air output port communicates with the inlet and supplies the cold air into the air cooling pathway to cool the mold core.

Disclosed is an injection mold. The injection mold includes a mold set having n molds (n is a natural number of 2) defining a cavity for injection molding a green body, and at least one ejector provided on at least one of the n molds to separate an injection-molded part from the mold set. The ejector is provided with a first heater capable of heating the mold set to a first temperature.

A shaping tool includes a cooling system having one or more cooling passages configured for enhanced cooling. The cooling passages provide latent heat cooling of a heated material that is in contact with a shaping surface of the tool. Cooling fluid flows along the cooling passages in a two-phase flow regime in which a portion of the cooling fluid is liquid and a portion of the cooling fluid is vapor. A two-phase portion of the cooling passage can be shaped to follow a three-dimensional contour of the shaping surface. Opposing walls of the cooling passage can be provided by passage surfaces of separately formed pieces of the tool. The latent heat cooling provided by suitably configured cooling channels extracts more heat from the material being shaped in the tool than traditional cooling systems.

A cooling system (10) for molding fixtures, and particularly for foundry molds, comprising:water treatment means (II)compressed air generation means (12)means (13) for pressurizing the treated watera device (14) for mixing air with the treated water, and for the controlled ejection of atomized water under pressure toward a cooling circuit (16) of a molding fixture.

The invention relates to a device for cooling a casting mold (14), comprising an evaporation chamber (18) formed in the casting mold (14), a first pump (23) for supplying a liquid to the evaporation chamber (18), and a second pump (30, 31) for applying a pressure in the evaporation chamber (18), which differs from the atmospheric pressure. The invention also relates to a corresponding method. The invention allows the cooling of a casting mold to be controlled in a targeted manner. This can be helpful in particular in the injection molding of plastic parts.

The invention relates to a tool insert for a primary shaping tool, comprising a thermal insulator disposed on a main part having a molding surface contacted by the molten material to be shaped, said surface being at least partly spaced from the main part of the tool insert by a thermal insulator. The thermal insulator comprises bulk metallic glass.

A molding system for directly gas-cooling a molding object includes a cold air provider, two molding parts, a plurality of outlets, at least one air-providing molding part, at least one air passage, and a controller. The two molding parts are closed detachably to co-define a forming cavity therebetween. The outlets are arranged on the air-providing molding part. The air passage is connected to the cold air provider and the outlets. The controller drives the cold air provider to provide cold air to a molding object in the forming cavity directly when the two molding parts are separating.
