[0038] In the figures, identical or similar parts / components have been given the same designations, wherein corresponding or comparable advantages can be achieved even if the description is not repeated for the sake of simplicity.

[0039] figure 1A cross-sectional view of a thermoforming die 1 according to the invention is shown. The thermoforming tool 1 is shown in the closed state. The deformed plate member 2 is located between the upper die 3 and the lower die 4 . The upper mold 3 and the lower mold 4 here comprise a base body 6 with cooling channels 5 . A heat removal fluid flows through these cooling channels 5 . A mold lining 7 is arranged on the base body 6 on the side of the sheet metal component. The mold lining 7 protects the base body 6 against high wear and forms the boundary of the mold cavity 8 .

Abstract

The present invention relates to a method for producing a hot-forming tool and a hot-forming tool with wear protection. The hot-forming tool (1) for hot-forming processing plate-shaped members (2) has at least one cooled upper tool (3) and a lower tool (4). The upper tool or lower tool (3, 4) has a base body (6) equipped with a molded bellow (7). The base body (6) is optimally made of aluminum alloy, and the molded bellow (7) is optimally made of steel. The molded bellow (7) is optimally used as a wear protective plate (9) or a metal coating (18) applied to the base body (6) and can implement good heat transfer (W) to the upper tool or the lower tool (3, 4) through the plate-shaped member (2) in a less thickness as less as possible. To improve heat radiation capacity, the base body (8) corresponding to the upper tool or the lower tool (3, 4) is provided with a cooling channel (5). The cooling channel (5) is used for flow guide of a heat radiation liquid.

Description

technical field [0001] The invention relates to a thermoforming mold for thermal processing of sheet metal components, comprising an upper mold and a lower mold, which have a base body made of non-ferrous metal which is easy to machine and a mold liner arranged on the base body, said base body having The cooling channel, the mold liner forms the boundary of the mold cavity of the thermoforming mold. [0002] The invention also relates to a method of manufacturing a thermoforming die for the thermoforming of sheet metal components, the thermoforming die comprising an upper die and a lower die having a base body composed of a non-ferrous metal that is easily machined and disposed on the base body A mold liner, the base body having cooling channels, the mold liner delimits a mold cavity of a thermoforming mold. [0003] The invention also relates to a method for separating a mold liner from a base body of a thermoforming mold. Background technique [0004] Hot forming dies ar...
