One-box multi-piece casting mold and casting method for brake disc castings

Abstract

The invention discloses a one-box multi-piece casting mold for brake disc castings, and belongs to a casting technology. The casting mold comprises an upper box, at least one middle box and a lower box which are superposed from top to bottom, wherein a round brake disc cavity and a straight pouring gate are formed in each middle box and the upper box; the straight pouring gates are vertically communicated; a plurality of upright inner pouring gates communicated with the brake disc cavities are formed in each middle box; a plurality of air outlet rods communicated with the brake disc cavities are uprightly arranged in the upper box; a transverse pouring gate, a round sub transverse pouring gate and transverse inner pouring gates are formed in the lowermost middle box; the diameter of the sub transverse pouring gate is smaller than that of the brake disc cavities; the transverse pouring gate is connected with the lower ends of the straight pouring gates and the sub transverse pouring gate; a plurality of transverse inner pouring gates are uniformly distributed circumferentially and connected with the sub transverse pouring gate and the brake disc cavities. A plurality of brake disc castings can be cast in one box, a sand-to-iron ratio is reduced, process yield is improved, production efficiency is improved, and production cost is reduced.

Description

technical field [0001] The invention belongs to casting technology, in particular to a multi-piece casting mold and casting method for a brake disc casting. Background technique [0002] When casting and producing wind power brake disc castings, only one casting is cast in one box (one mold) (see figure 1 ), the production efficiency is low, and because the sand-iron ratio (the ratio of the weight of the sand to the weight of the casting to be used when producing a casting) is high, the process yield (the weight of the casting accounts for the weight of the riser used to produce the casting and the weight of the casting The percentage of the sum of the weights) is lower, resulting in higher production costs. Contents of the invention [0003] The purpose of the present invention is to provide a multi-piece casting mold and casting method for brake disc castings to improve production efficiency and reduce production costs. [0004] In order to achieve the purpose of the p...
