PURPOSE: To provide a raw material for manufacturing a dental mold component and its holding device. CONSTITUTION: The ceramic main body 2 of a raw material 1 is stuck to the base section 4 of an aluminum support section 3. A fixed section is formed as a conical pin 6 rotation-symmetrical with a support axis 5, and it has a circular coupling groove 7. A hole 8 is provided in parallel with the support axis 5 on the base section 4. When the raw material 1 is machined, the conical pin 6 is inserted into the receiving opening section 10 of a holding device 9 to a limit stop point that the conical face of an opening pin formed analogously to the conical face of the conical pin 6 is coupled, and the conical pin 6 is fixed by a ball 11 excited by an elastic ring 12 and protruded into the coupling groove 7. A fixed pin 13 enters the hole 8 of the base section 4 to fix the raw material 1. An ejector 14 for removing the raw material 1 is provided. The raw material 1 is fixed to a clamp 15, and the clamp 15 is fastened and fixed to a clamp support section 16 by a nut 17. |
