AI Technical Summary
Titanium alloy forgings are difficult to measure precisely after die forging, especially the hardness of inclined and arc surfaces. Furthermore, the inconsistent dimensions of each forging make fixing difficult, making accurate hardness testing impossible.
By using a plaster mold and combining plaster modules and clamping plates, the forging is precisely placed in the plaster. After the plaster solidifies, it is processed to make the bottom of the mold form a specific angle with the surface of the forging, so as to achieve hardness measurement of any part of the forging.
It improves the accuracy of hardness testing of forgings, avoids problems with the size matching of molds and forgings and the risk of surface damage, reduces mold wear, and saves production costs.

Abstract
Claims
1. A precision measurement of the hardness of titanium alloy forgings gypsum mold characterized by, include: Mold box, plaster module, clamp plate; The clamp plate holds the forging along the parting surface. The mold box was filled with plaster; When the plaster mold has not solidified, the forging is placed on the plaster parallel or perpendicular to the parting surface; the clamping plate is placed on the mold box and the plaster. For forgings placed parallel to the parting surface, the upper surface of the plaster mold is parallel to the parting surface of the forging. For forgings placed perpendicular to the parting surface, the upper surface of the plaster mold is parallel to the cross-section of the forging. The plaster solidifies into plaster modules, and the mold box and clamp plate are removed.
2. The gypsum mold of claim 1, wherein, The bottom of the plaster module is machined to be parallel to the parting surface, ensuring that the resulting acute angle is 90-d1°; D1 is the angle between the surface to be measured on the forging and the parting surface.
3. The gypsum mold of claim 1, wherein, The bottom of the plaster module is machined to be perpendicular to the parting surface, ensuring that the resulting acute angle is 90-d2°; d2 is the angle between the surface of the forging to be measured and the horizontal plane.
4. The gypsum mold of claim 1, wherein, The die box size must be larger than the outline size of the forging.
5. The plaster mold according to claim 3, characterized in that, When a forging is placed perpendicular to the parting surface, the depth at which it is placed shall not exceed the measured surface.
6. The gypsum mold of claim 1, wherein, The plaster modules were removed using a destructive method.
7. The gypsum mold of claim 1, wherein, If the bottom and top surfaces of the forging are convex, the clamping plate's locking opening is located below the parting surface, and the locking opening conforms to the shape of the bottom and top surfaces of the forging.
8. The gypsum mold of claim 1, wherein, If the bottom and top surfaces of the forging are flat or concave, the clamping plate consists of two symmetrical clamping plates. After the two clamping plates are clamped together, the resulting interlocking opening conforms to the shape of the bottom and top surfaces of the forging.
