Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the utility model, its application, or uses.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

Referring to fig. 1-3, in the present embodiment, a casting system for reducing bearing housing blowholes is provided, including: the device comprises an I-shaped plate 1, wherein a first connecting column 3 is arranged on one side of the I-shaped plate 1, a second connecting column 5 is arranged on one side of the first connecting column 3, and first fixing blocks 6 are arranged on the second connecting column 5 and the first connecting column 3;

the two sides of the first fixing block 6 are provided with fixing cylinders 9.

The pouring system comprises two pouring gates, namely a bottom pouring gate and a transverse pouring gate, wherein the two pouring gates are pressure reduction pouring gates, sand washing is reduced, impurities are filtered by water entering through a thin sheet, the transverse pouring is a transverse special-shaped pouring head, and feeding and hole shrinkage are realized while the water inlet amount is increased.

By changing the thin slices into two shunting thin slices, under the condition of sufficient flow, after molten iron enters the pouring cup, the molten iron enters the thin slices in two paths, and most of sand is filtered by the thin slices; the overlap joint is changed to be small, and the residual sand which is not filtered can be directly filtered by the overlap joint on the premise of ensuring that the flow is not lost. The position of the thin sheet at the gate and the position of the arc-shaped gating system are exchanged, so that the gate position can be flush with the step on the casting, excessive polishing in the polishing process can be reduced, the possibility that the step is polished is reduced, and the gate is milled flat. The angle formed by the pouring gate and the casting is too small, so that the stripping can be influenced, and the sharp-angled sand formed at the pouring gate can be washed away by molten iron to form casting sand holes. And a part of bevel edge is milled off from the pouring gate, so that the angle formed between the pouring gate and the casting is increased while the draft angle is increased, and the sharp-angled sand is not easy to generate.

Referring to fig. 1, in the embodiment, a connecting block 4 is installed on one side of a first connecting column 3, a second connecting column 5 is installed on one side of the connecting block 4, arc-shaped plates 7 are installed on both sides of a first fixing block 6, two connecting plates 8 are installed on one side of the arc-shaped plates 7, the two connecting plates 8 are installed on a fixing cylinder 9, a second fixing block 2 is installed on an i-shaped plate 1, and a T-shaped block is installed on one side of the second connecting column 5, so that the situation that the fixing cylinder 9 shakes during use is reduced.
