The existing brake calipers The molds are set up and down, and the cylinders are placed vertically downwards. Generally, there are four to six mold cavities, and each cavity is fed by two risers. It is found in actual production that this scheme is iron The liquid enters from the two risers and is easy to gather at the cylinder, causing turbulence, slag inclusions, pores and other defects, and because each cavity needs two risers on both sides for feeding, the product yield rate is low, which is harmful to castings. Both yield and quality are adversely affected.

In order to realize the purpose of the invention, the utility model adopts the following technical solutions:

A pouring system for automobile brake caliper body castings, including sprue cups, multiple castings, runners and sprues, runners are provided at the lower end of the sprue cups, and runners are provided on both sides and the middle of the runners There are connected sprues, and the sprues on both sides are respectively connected with the ingates at the bottom of the casting, and there are casting risers near the cylinder of the casting, and the sprues in the middle are respectively connected to the water inlet of the casting riser. Overlap sprue connections.

The casting system of the automobile brake caliper body casting includes four mold cavities arranged up and down, each row is set as two mold cavities, and castings are arranged in the mold cavities, and each casting cylinder barrel extends horizontally to The vertical direction is inclined at 25°, and the cylinder with the largest thermal section faces upward.

In the gating system of the automobile brake caliper body casting, the sections of the runner and the sprue are both trapezoidal.

In the pouring system of the automobile brake caliper body casting, the die cavity risers are all selected with a diameter of 60mm, the cross-sectional area of the inner gate arranged at the bottom of the upper row of castings is 20mm²*2, and the cross-sectional area of the inner gate arranged at the bottom of the lower row of castings is It is 15mm²*2, and the flow ratio between the upper part and the lower part of the adjacent casting is 1:1.

Due to the above-mentioned technical scheme, the utility model has the following beneficial effects:

The pouring system of the automobile brake caliper body casting described in the utility model, by placing the casting at an angle of 25°, in order to feed the thick and large parts of the casting, a riser is set near the cylinder of the casting, and the two sides are directly poured The sprue in the middle is connected with the sprue at the bottom, and the sprue in the middle is connected with the overlapping sprue of the casting riser, which makes the filling of the whole system stable, and the multi-layer lap joint makes the slag avoidance effect good. The casting of the utility model has good appearance quality and no loose defect inside, which effectively improves the yield of the casting and reduces the cost.
