Iron-type coated-sand casting disc brake caliper body and producing method thereof

Abstract

The invention discloses an iron-type coated-sand casting disc brake caliper body and a producing method thereof, and belongs to the field of iron-type coated-sand casing. The iron-type coated-sand casting disc brake caliper body comprises a caliper main body, a left-end fixing and supporting installing hole site, a right-end fixing and supporting installing hole site, a brake air cylinder installing groove, a brake mechanism cover hole, a synchronous adjusting chain wheel cavity groove and a brake disc installing part. The left-end fixing and supporting installing hole site and the right-end fixing and supporting installing hole site are symmetrically arranged on the two ends of the caliper main body, the brake air cylinder installing groove is arranged on the upper portion of the middle of the caliper main body, the brake mechanism cover hole is formed in the one side of the middle of the caliper main body, the synchronous adjusting chain wheel cavity groove is formed in the middle of the caliper main body, and the brake disc installing part is arranged in the middle of the caliper main body. According to the iron-type coated-sand casting technology, the technology yield is high, the organization is compact and free of leakage, the overall performance is high, the used sand is little, the equipment investment is low, the production cycle is short, the effect is rapid, the equipment occupation area is low, the production efficiency is high, the manufacturing cost is low, and the environmentally friendly performance is good.

Description

technical field [0001] The invention relates to the field of iron mold sand-covered casting, in particular to an iron mold sand-covered casting disc brake caliper body and a production method thereof. Background technique [0002] Iron mold sand-coated casting is a casting process in which a thin layer of molding sand (also known as coated sand) is covered around the inner cavity of a metal mold (also known as iron mold). It is a combination of metal mold casting and shell casting. The obtained castings have the advantages of high dimensional accuracy, good mechanical properties, saving labor, materials and equipment, and low production costs. [0003] A special casting technology method developed by Chinese foundry workers on the basis of domestic and foreign foundry peer research combined with my country's national conditions is different from sand casting, lost foam solid mold casting, V method casting, metal mold casting, and shell mold casting. A semi-precision casting...

AI Technical Summary

Problems solved by technology

The ordinary sand mold and resin sand casting process have problems such as complex process, loose structure, poor surface quality, unguaranteed overall mechanical properties and low yield, while iron mold sand-coated casting is in the rough forming process. The inner cavity of the metal mold (called the iron mold) is covered with a thin layer of sand to form a mold. Through the reasonable control of the weight, wall thickness and thickness of the sand layer of the iron mold, the filling, solidification and cooling process of the casting can be achieved within It is completed under an ideal condition, and the factors that cause casting defects can be eliminated to the greatest extent, so that the quality of castings can be greatly improved
