Abstract
PURPOSE: To eliminate the difference in position of a cutting place by a method wherein a trimming blade and a plug bar capable of projecting and retreating freely are provided on the concave and convex dies of a drawing mold, the sheet is pressed by the plug bar on the occasion of the closure of the mold and then the trimming blade is made to operate jointly.
CONSTITUTION: The synthetic resin sheet 1 is strectched between both outside clamps 2, and when the upper and lower drawing dies 3 are closed, first the sheet 1 is pressed down by the plug bar 8 and turned back and introduced into a cavity part 5, while the trimming blade 7 is made to operate to give a cut 13. By this method, the difference in position of the cutting place, which happens in other method wherein the cut is given selarately beforehand, can be eliminated.
