Embodiment Construction

[0020] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] figure 1 is the structural diagram of sand core molding, figure 2 is a schematic diagram of the sand core, image 3 is the structural diagram of the rear brake disc, Figure 4 is a schematic diagram of the cold iron structure, Figure 5 is the schematic diagram of the microalloy vanishing ring, Image 6 It is a schematic diagram of a sand molding machine.

[0022] Such as Image 6 As shown, the working process of the sand molding machine 1 is to send the molding sand 12 into the sand bucket 11 of the sand molding machine 1 (the existing ordinary molding machines can be made, and the molding machine production line can continuously produce sand molds in large quantities, and the production efficiency is very high). Blow the molding sand 12 in the sand bucket 11 into the molding chamber 13, and s...

Abstract

The invention provides a novel high-strength casting mould structure for a car brake disc. The novel casting mould structure is formed by compounding two outer moulds and a sand core, wherein the sand core is located in the outer moulds. According to the novel casting mould structure, the strength, the toughness, the weather resistance and the processability of a rear brake disc for a car are improved. A micro-alloy vanishing ring is additionally arranged at an R angle part which easily generates inner looseness in the casting mould so as to improve the strength and the toughness of a casting. The casting is commonly molded by the sand moulds and the sand core; a casting system is arranged in the sand core; a ceramic filtering sheet, an annular liquid inlet sheet, a chilling block and a dead head of the casting system are arranged reasonably so that the defects of the casting are improved and the product quality is improved.

Description

technical field [0001] The invention relates to an automobile part, in particular to a novel casting model structure of an automobile brake disc. Background technique [0002] At present, in the foundry industry at home and abroad, the automatic molding production line is generally divided into two types according to the different types, namely the horizontal molding production line and the vertical molding production line. Since the rear brake disc with solid structure has no internal cavity structure, no sand core is needed in general production, and it only needs to be formed by sand mold. However, in the vertical molding line production, the castings produced by this conventional method often have internal shrinkage defects at the R angle where the braking surface and the assembly surface are connected. During the stress process of the brake disc, due to the existence of shrinkage at this place, the brake disc will have a tendency to break due to the concentrated force....
