The utility model relates to a precision casting wax pattern mould which comprises a lower mould, a moving core and a demoulding ejecting part, wherein the moving core is assembled on the lower mould along an up-down direction in a guide movement manner; the upper end of the demoulding ejecting part is matched with a corresponding wax press in a force transfer manner; and the demoulding ejecting part is provided with at least one ejecting rod which extends along the up-down direction and is used for ejecting the upper end of the moving core. When a wax pattern and the moving core need to be demoulded, the wax press is utilized for transferring force to the demoulding ejecting part, the ejecting rod positioned on the demoulding ejecting part is used for ejecting the moving core so that the moving core is separated from the wax pattern, and the wax pattern and the moving core are demoulded through the mechanical force of the wax press, so that the labor intensity of an operator can be alleviated; in addition, the ejecting rod and the moving core are matched in an ejecting manner so that the wax pattern and the moving core are separated, and the ejecting rod can not contact with the wax pattern, so that the problem that the wax pattern is easy to damage is prevented.
