The invention discloses a wax mold vertical position positioning device and positioning method for precision casting, which relate to the technical field of precision casting and include a base, a center rod, a vertical sliding positioning mechanism, a circumferential rotation positioning mechanism, a radial positioning and indicating mechanism, and a central The side wall of the rod is provided with a height scale along the height direction of the central rod, the vertical sleeve is slidably sleeved on the central rod, the side wall of the supporting ring is provided with a circumferential scale along the circumference of the supporting ring, and the connecting circle The ring is rotatably set on the upper part of the vertical sleeve, the side wall of the radial positioning rod is provided with a radial scale along the length direction of the radial positioning rod, the radial sleeve is slidably installed on the radial positioning rod, and the indicating rod is fixed At the bottom of the radial sleeve, the lower end of the indicating rod is provided with a tip indicating part. The wax pattern vertical position positioning device and positioning method for precision casting realize the position control in the vertical direction in the combination stage of the precision casting wax pattern, and the control accuracy is high, and the influence on the crystal growth orientation of the casting is avoided.
Description
technical field [0001] The invention relates to the technical field of precision casting, in particular to a vertical position positioning device and a positioning method of a wax mold for precision casting. Background technique [0002] In the process of precision casting, the vertical direction of the membrane shell is closely related to the filling process, temperature field setting, solidification process, etc., especially in the process of directional solidification, the vertical direction of the membrane shell basically determines the crystal growth orientation of the casting. In the mold assembly stage, the vertical position control of the wax mold is particularly important. However, there is no relevant device for controlling the vertical position of the wax model in the prior art, which makes the control of the vertical position of the wax model inaccurate and affects the crystal growth orientation of the casting. SUMMARY OF THE INVENTION [0003] In order to sol...
