Problems solved by technology

The disadvantage of resin sand casting is that it is rough, the shape is not vivid, and it cannot make complex shapes; the casting of paraffin precision casting is delicate, and complex shapes can be completed, but the process is complicated, the cost is high, and the time is long, and only small pieces can be produced. Large pieces, easy to deform, gypsum casting is used more in the casting of craft products, the benefits can be enlarged, and it is not easy to deform, and its disadvantages are high cost and long cycle

Embodiment Construction

[0018] The problem to be solved by the present invention is that the disadvantages of resin sand casting are that it is rough, the shape is not vivid, and complex shapes cannot be made; the casting of paraffin precision casting is delicate, and complex shapes can be completed, but the process is complicated, the cost is high, and the time is long, and it can only be produced. Small products cannot be made into large ones, as they are easily deformed.

[0019] The technical solution adopted by the present invention to solve the problems of the technologies described above is as follows:

[0020] A casting process is characterized in that: comprising the following steps:

[0021] 1) Manufacture appearance: After polishing the finalized metal components or newly produced product models, wipe the surface with pure cotton cloth, and then apply Vaseline evenly on the surface;

[0022] 2) Making the outer silicone mold: use silicone rubber to make a silicone mold with multi-layer co...

Abstract

The invention relates to a process, in particular to a casting process. The casting process is characterized in that it includes the following steps: making a pattern: making a silicone outer mold: making a wax mold: modeling; pouring, sand falling and finishing: pouring smelted liquid metal into a resin quartz sand mold, and then Cooling, shelling, and polishing of supporting metal components. The beneficial effects of the invention are: low cost, short cycle, not easily deformed, and capable of making large and very complicated items. The cost is the lowest among all casting processes, it is not easy to deform, it can make large and complex castings, the cycle is short, the pollution is small, the collapse is excellent, and the material recycling rate is high, which greatly solves the bottleneck of the casting process. Casting technology has been raised to a new level.

Description

technical field [0001] The invention relates to a process, in particular to a casting process. Background technique [0002] Casting technology is one of the basic processes of modern machinery manufacturing technology. Metal component casting is to melt metal into liquid metal that meets certain requirements, pour it into the casting cavity, and obtain the predetermined shape, size and performance after cooling and solidification and sand cleaning. The casting process. Commonly used casting techniques in the prior art include resin sand casting, paraffin wax precision casting and the like. The disadvantage of resin sand casting is that it is rough, the shape is not vivid, and it cannot make complex shapes; the casting of paraffin precision casting is delicate, and complex shapes can be completed, but the process is complicated, the cost is high, and the time is long, and only small pieces can be produced. Large pieces are easy to deform. Gypsum casting is often used in th...
