Claims

[Scope of utility model registration request]

A concave groove extending to both end faces is formed in the template, and a core having a cavity and a coefficient of thermal expansion smaller than that of the template is inserted into the groove, and a core having a pressing protrusion in the center and a concave end is formed. Holding plates having stepped portions are placed on both end faces of the template, and are inserted into the holes in the holding plate with a gap between the concave stepped portions and the end faces of the template. A mold made by screwing the tip of a fixing screw passed through it into the mold plate, and using a spring attached to the fixing screw to bring the presser protrusion of the presser plate into close contact with the cavity.
