Upper pitched roof fixing structure of injection mold

The invention relates to the technical field of mold equipment, in particular to an upper pitched roof fixing structure of an injection mold, compared with the prior art, the upper pitched roof fixing structure of the injection mold is provided with a glue position surface and a surface A on a pitched roof, and the glue position surface and the surface A are located on the same horizontal plane; the side surface of the glue position surface is provided with a surface B, the surface B is formed by a strip-shaped convex shaft, the surface B extends to the position of the surface A from the top end of the pitched roof, and the surface B is longer than the glue position surface, so that the characteristics of the surface B are increased, and the glue position direction of the pitched roof is positioned through the contact surface of the surface B and a mold; therefore, the pitched roof is sufficiently restrained in four directions, and the stability of the pitched roof during ejection is ensured. 本发明涉及模具设备技术领域，特别
