Embodiment Construction

[0064] Figure 1a Shown is a schematic view of a double-layer carbon brush 10 comprising a first cast layer 11 and a second cast layer 12 . In the illustrated embodiment, the first cast layer 11 is a copper layer composed of several copper particles 13 , and the second cast layer 12 is a carbon layer composed of several carbon particles 14 . Figure 1a The shown double-layer carbon brush 10 is continuously manufactured in the manner shown in Fig. 4a to Fig. 4f by a molding machine 15. The molding machine 15 includes a mold 16 provided with a molding sliding device 17, and the pressing surface device 18 of the mold 16 is as shown in FIG. Figure 1b shown. by comparison Figure 1a with Figure 1b It can be seen that the pressing surface device 18 includes two pressing surfaces 19 , 20 corresponding to the basic areas 21 , 22 of the first casting layer 11 and the second casting layer 12 of the double-layer carbon brush 10 respectively.

Abstract

The invention relates to a method and a device for manufacturing a multi-layer compression molded element and to a compression molded element which is embodied as a multi-layer carbon brush and has at least a first and a second molding layer, in which, in order to carry out the method, a multi-component mould which comprises a molding element and a mould slide arrangement interacts with a molding die, and in which a mould which is defined by the selected configuration of the molding slide arrangement in the molding element is filled by filling molding segments which are formed one next to the other with molding material in chronological succession in a transverse direction with respect to the axis of the molding die, and by the compression molded element being subsequently formed by moving the molding die and molding slide arrangement relative to one another in the mould.

Description

technical field [0001] The invention relates to a method for the production of a multilayer die-casting module provided with at least one first casting layer and a second casting layer, comprising the following steps: a multi-part forming tool provided with a forming element and a forming slide and die interaction; filling the mold defined by the position of the molding slide in the molding element so that the casting material successively fills adjacently arranged moldings in a direction perpendicular to the axis of the die; and, in the mold The die and forming slide are moved relative to each other to form a die casting mold. In addition, the present invention also relates to a manufacturing device of a multi-layer die-casting mold, and a multi-layer carbon brush produced according to the manufacturing method and manufacturing device of the multi-layer die-casting die. Background technique [0002] In the prior art, a double-layer carbon brush is a typical die-casting mod...
