[0002] In the known precision casting process, several wax modules are placed on a runner, a layer of sand shell film is made on the surface of the wax mold, and then the wax mold is melted, and then the molten metal is poured. When the rough casting is completed, the sand shell mold used for casting is removed, presenting a structure in which several finished castings are connected on two or four sides of a runner, and a conical pouring cup is left at one end of the runner. Therefore, the work after removing the sand shell is to cut it off from the runner. The mold structure of investment casting is complex and changeable, and the mold cutting operation is arduous and labor-intensive, and there are certain safety hazards. Therefore, mold cutting has always been a long-standing problem in the investment casting industry, and there are many problems.

This greatly reduces the convenience of the operation and has a negative impact on the cutting efficiency. This temporary and irregular operation method has significant potential safety hazards.
