Several design elements of precision casting

H2. Precision casting structure design should accord with the requirement of machine equipment itself and mechanical processing manufacturability requirements, should also meet the requirements of the casting process, casting structure design should pay attention to the following points：

H3. 1. To facilitate manufacturing model, core box and modeling:

Small mixer, u-shaped mixing machine casting lumen should try to be without or with less casting cores, when using core, should be convenient for the support, fixed and exhaust sanding, should have enough technology hole when necessary；

For the inner and outer sides of the casting and reinforcing ribs, there should be a certain structure slope in the starting direction;

The convex part of the casting and the casting body should not be too big, it is better to take the same height, the distance on the same surface is closer to several convex platforms, it is better to connect the whole convex part；

The shape of the casting should be simple, so that the mold can be formed, and the parting surface should be as flat as possible.

H4. 2. To reduce the tendency of casting defects:

It is necessary to avoid large horizontal plane in the casting；

Casting holes in the surface wall of the casting should be reinforced with convex edges to reduce wall thickness；

The casting structure should be reduced as much as possible to allow it to contract without hindrance；

There should be a number of connecting columns in the interlayer cavity of the casting inner waterway and gas path.
