METHOD FOR FORMING SUPPORT PATTERN

摘要

The present invention provides a method for forming a support pattern, wherein: holes are formed at both sides of a plate material, to which a support pattern for supporting a support member that is inserted between molded products is to be formed by respectively forming protrusion patterns to the molded products; the deformation of the plate material is prevented by simultaneously chamfering the upper and lower portions of the outer peripheral portion of a support pattern forming section to which the support pattern is formed, or simultaneously chamfering the upper part or the lower part of the plate material adjacent to the outer peripheral portion of the support pattern forming section together with the outer peripheral portion of the support pattern forming section; the support pattern protrudes by forming the plate material between the both holes; and slots are punched in so as to mutually connect the molded products.
