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. Thro

Embodiment 1

[0034] Embodiment 1 of the present invention provides a disc brake caliper body cast with iron mold sand-covered, see Figure 1 to Figure 3 , the disc brake caliper body of the iron mold sand-covered casting includes a caliper body body 1, a left end fixed support installation hole 2 and a right end fixed support installation hole 3 arranged symmetrically at both ends of the caliper body body 1, and a fixed support installation hole 3 arranged on the caliper body body 1 Brake cylinder mounting groove 4 in the middle upper part, brake mechanism cover hole 5 set on the middle side of the caliper body body 1, synchronous adjustment sprocket chamber groove 6 set in the middle of the caliper body body 1, set on the caliper body body 1 Brake disc mounting part 7 in the middle part.

Embodiment 2

[0036] Embodiment 2 of the present invention provides a production method of a disc brake caliper body cast by iron mold sand-covered casting, see Figure 4 , the production method of the disc brake caliper body of the iron mold sand-covered casting, the steps are as follows:

[0037] S101. Shape:

[0038] The outer sand box is made of iron mold, and the coated sand is resin sand. The inner cavity of the iron mold is made according to the shape of the brake caliper body, and the thickness of the sand layer is 5mm-30mm; The gate, horizontal gate and filter screen adopt closed gate; the highest perforation and core head of the upper half mold are equipped with air hole needles, and do not pass through the box surface; evenly on the parting surface of the iron mold Exhaust grooves are distributed; heating devices are installed in the middle of the upper and lower mold bottom plates of the outer mold, and the mold temperature and iron mold temperature are controlled at 180-240°C,...

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...
