Abstract

The invention relates to the technical field of casting molds, in particular to a precision casting complex core mold and a use method thereof. The mold comprises a mold base and a mold upper mold which are matched up and down, a mold cavity is formed between the mold base and the mold upper mold, a ceramic core is mounted in the mold cavity, a lower core support for supporting the ceramic core ismounted on the mold base, an upper core support for fixing the ceramic core is mounted on the bottom end of the mold upper mold, one end of the mold cavity is provided with a sliding block for fixingthe ceramic core, the material of the upper core support and the material of the lower core support are the same with the material of pour steel, the ceramic core is supported through the upper coresupport and the lower core support to obtain a wax part with a core support, through the wax part, a shell is made, molten steel is poured into the shell, through the upper core support and the lowercore support, the ceramic core is supported, and the condition that due to molten steel instant impact and pressure, the position of the ceramic core is deviated can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of casting molds, in particular to a precision casting complex core mold and a method for using the same. Background technique [0002] As we all know, investment casting is more commonly used in precision casting, also known as lost wax casting: select suitable investment materials (such as paraffin) to make investment patterns; repeatedly dip refractory coating and sprinkle refractory sand on the investment pattern, harden the shell and Drying; then melt the internal investment pattern to obtain the cavity; roast the shell to obtain sufficient strength, burn off the remaining investment material, and pour the required metal material; solidify and cool, and remove the sand after shelling, so that Obtain high-precision finished products. [0003] When the existing precision casting complex core mold is pouring, the ceramic core is prone to deflection due to the instantaneous impact and pressure of pouring m...
