Holosymmetric fused quartz structure blowing mold and preparation method

The invention discloses a blowing mold with a holosymmetric fused quartz structure and a preparation method, the blowing mold with the holosymmetric fused quartz structure comprises a mold body which is made of graphite and is provided with a blowing structural body with a fused quartz structure in the middle, and a silicon carbide film is arranged on the surface of the mold body. The preparation method of the blowing mold with the holosymmetric fused quartz structure comprises the following steps: cutting a graphite rod into a graphite blank; carrying out mechanical rough machining on the graphite blank to finish structure forming; cleaning the graphite blank with the structure formed, and forming a silicon carbide film on the front surface; carrying out mechanical finish machining on the graphite blank with the silicon carbide film; and the graphite blank is polished, and the prepared blowing mold of the holosymmetric fused quartz structure is obtained. The invention aims to obviously ...
