Such continuous installation and disassembly, reinstallation and disassembly, is very labor-intensive and not very convenient to operate.

[0003] For example, the utility model with patent number CN202123407620.1 discloses a hydraulic valve body casting model, including an upper mold shell and a lower mold shell detachably connected to the upper mold shell; positioning rods are vertically fixedly installed on both sides of the upper mold shell near one end of the lower mold shell. The hydraulic valve body casting model uses positioning rods and positioning grooves. When the upper mold shell and the lower mold shell are spliced, the positioning rod can be inserted into the interior of the positioning groove for auxiliary positioning, so that the cavity between the upper mold shell and the lower mold shell is connected, and then the rotating disk is rotated so that the rotating disk drives the moving seat to move through the first connecting rod, so that the fixed block is stuck in the interior of the positioning rod to fix the positioning rod. The structure is simple and easy for the staff to assemble. While reducing the probability of errors, it can prevent the staff from shaking between the upper mold shell and the lower mold shell when moving the spliced ​​mold shell, resulting in errors, thereby improving stability;

[0004] The hydraulic valve body casting model in this patent is provided with a positioning rod for positioning, which can avoid position errors between the upper mold shell and the lower mold shell, but the model cannot quickly cool the model and remove the valve body, and the operation is not very convenient.
