Abstract
Disclosed is a method for manufacturing a punch, which includes the steps of injection-molding a jig with melted materials so that a lower plate and an upper plate are integrally formed at least partially to connect cutting holes to be formed in the lower and upper plates and also so that a convex embossment is formed on the lower plate; cutting a connection portion of the lower and upper plates to form a gap in which a sheet member is to be supplied so that the cutting holes are separated between the lower and upper plates, the cutting work being conducted so that an upper surface of the lower plate is formed to have a height greater than an upper surface of the formed convex embossment; and assembling a punching member, which includes at least one first punch pin passing through the cutting holes to punch the sheet member and form a predetermined pattern therein and a second punch pin having a concave embossment at a front end thereof in correspondence to the convex embossment, to the jig.
