Abstract

The invention discloses a casting mold of a shell mold. The independent mold core occupies the position of the casting mold of the shell mold and occupies the position of which the weight needs to be reduced so that the area cannot be filled with wax liquid in the forming process of the water meter shell mold, a cavity is formed, the weight reducing effect is achieved, and the wall thickness is uniform. According to the invention, the product quality of the water meter shell can be ensured, and the production efficiency of the wax blank and the water meter shell is improved.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a casting mold for a shell mold and a mold opening and closing method thereof. Background technique [0002] The existing production processes of the shell mainly include: investment casting in which the two halves of the wax billets are bonded and assembled into one, and forging / stamping after parting and then welding. [0003] When the two-half wax blank process is used, the shell needs to be divided into two halves and then fixed and assembled with an adhesive after the wax blank is made. During the assembly process of the two half wax blanks, the shell is easily deformed, dislocated, and the gap in the inner cavity is easy. Inadequate bonding occurs, resulting in casting defects such as shell inclusions and shrinkage porosity. [0004] When the steel plate type welding process is adopted, the shell is welded by each part, and the product size accuracy error is large; the weldi...
