Problems solved by technology

[0005] Disadvantages of cured organic sheet semi-finished products are in particular: high costs for semi-finished products; poor energy balance (two to three heatings are necessary for curing, forming and heating for encapsulation injection or covering injection); Multiple or sometimes expensive handling equipment; necessary trimming of organic sheet or component edges and necessarily higher manufacturing tolerances for cured organic sheet inserts to prevent tooling damage

Embodiment Construction

[0031] figure 1 The initial situation of the method for producing an injection-molded component 1 with an inlay made of organic sheet 2 is shown, in the illustrated example, the injection-molded component 1 is provided with two inlays made of organic sheet . The inlay is part of an as yet uncured continuous organic sheet, which is wound on a roll 3 and provided before the actual injection mold 4 .

[0032] A heating station 5 is arranged between the injection molding tool 4 and the roll 3 .

[0033] In a first method step, the front section of the continuous organic sheet is drawn off from the take-up roll 3 and introduced into the heating unit 5 by means of a gripping device, not shown. exist figure 2 This is shown in .

[0034] In the heating unit 5 , the section of the organic sheet 2 located in this heating unit 5 is heated to a temperature above the forming temperature of the organic sheet 2 .

[0035] After the heating phase has ended, the section of the organic s...

Abstract

The present invention relates to a method for producing an injection-moulded component with an inlay made of an organo-sheet, comprising the following steps: providing a not yet consolidated endless organo-sheet (2) wound on a roll (3), pulling away a leading section of the endless organo-sheet from the roll and introducing said section into a heating unit (5), heating the section to a temperature above the moulding temperature, introducing the heated section into an opened injection mould (4), without separating the heated section from the endless organo-sheet, such that a further section of the endless organo-sheet is automatically drawn from the roll and introduced into the heating unit, closing the injection mould and simultaneously severing the heated section from the endless organo-sheet, producing the injection-moulded component by moulding the severed section and then insert moulding or overmoulding of the moulded section. The invention further relates to a corresponding device and a corresponding moulded component.

Description

technical field [0001] The invention relates to a method for producing an injection-molded component with an inlay made of organic sheet metal, a device for carrying out the method and an injection-molded component produced according to the method. Background technique [0002] Organic sheets are fiber composite materials that are currently used mainly in automobile and aircraft construction. Additional potential exists in the manufacture of (vehicle) front ends, seats, brackets / beams and pedals. [0003] Organic sheets are fiber-matrix semi-finished products. They consist of fibrous fabrics or mats of fibrous mats embedded in a thermoplastic matrix. The advantage of thermoplastic matrices lies in the thermoformability of the semi-finished product and the resulting shorter process times than conventional thermosetting fiber composites. This is of particular interest in the automotive industry with its short process times. Frequently used fiber materials are glass, aramid...
