Process for the preparation of molds for pressure casting, especially for casting aluminum alloy crosses and die pressure casting, especially for casting aluminum alloy crosses
mold for casting pressure is a combination steel fixed part (1) with a steel form part of mobile forms. in the fixed part form (1) and in a mobile part forms are part of the forming surface shape, where part of the outgoing shape fixed part forms (1) has shape of a five pointed star and a fixed part (1) forms out core (1c).the bottom part of the outgoing surface shape in the fixed part form (1) is concave openings forming cooling channels. mobile part forms are arranged symmetrically in relation to the arms. in the fixed part form (1) with part of the mobile form of the outer edges of the outgoing part continuous forms (1) adjacent to the edge outer part of the outgoing part movable form.in the surface of the cavity nest, in part a fixed form (1), there are pockets (10), and by the wall fixed part (1) through the holes forms cooling channels (11) and fixing holes (12). (10) are embedded in its cutting inserts (13) forming, with fragments of their surface form the surface indentations to nest in the fixed part form (1).in wku0142adkach cooling (11) are cooling channels (13a) cutting inserts (13), whereby the outgoing of wu0119u017cownicu0119 recalls. cooling channels (4) are connected hydraulically with the main cooling channels (13a) formed by cutting inserts (13). diaphragm cutting forming (13) are fixed in a fixed part of form (1).
