Abstract
PURPOSE: To perform piercing simultaneously with molding and achieve saving of manpower and material cost by superposing the peak ends of the two groove parts formed by the convex flights running from the respective root parts of mutually forward and backward moving male die and female die toward their ends.
CONSTITUTION: For example, in piercing shaft holes 4a, through-holes 4b, etc. for a pair of brackets 4c of an antisubsidence tray 4 of stanchions, the male die 8 and female die 9 for forming the bracket 4c parts are provided with convex flights 8', 9' respectively running from their root parts to the ends, these being so formed that the convex flights 8', 9' make contact with each other during pressure working. In this way, the superposed part 10 is created in the end parts of the groove parts 6, 6' formed by the convex flight 8' and the groove parts 7, 7' formed by the convex flight 9', whereby the shaft holes 4a of through-holes 4b are formed. In the case of providing the shaft hole 4a in one bracket 4c, provision of two of the foregoing convex flights to either one in consideration for the stability of the support part suffices.
