Abstract

The invention relates to a casting mold of a shell mold. The casting mold comprises a main body mold plate with a combined mold cavity and a combined mold core fixedly clamped in the combined mold cavity. The combined mold cavity comprises a main mold core mold cavity, a water inlet mold cavity and a water outlet mold cavity; the main mold core mold cavity is positioned on one side of the main mold plate and extends inwards; the water inlet mold cavity is positioned on one side of the main mold core mold cavity and is communicated with the main mold core mold cavity; the water outlet mold cavity is positioned on the other side of the main mold core mold cavity, is opposite to the water inlet mold cavity and is communicated with the main mold core mold cavity; the combined mold core comprises a main mold core fixedly held in the main mold core mold cavity, a water inlet mold core fixedly held and inserted in the water inlet mold cavity and contacted with one side of the main mold core, and a water outlet mold core fixedly held and inserted in the water outlet mold cavity and contacted with the other side of the main mold core, and the combined mold cavity is an annular structure and is sealed in the main body mold plate; and the combined cavity further comprises a core groove which is arranged between the main core cavity and the water outlet cavity and is used for connecting and transitioning the main core cavity and the water outlet cavity, and the combined core further comprises an independent core arranged in the core groove.

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...
