Abstract
PURPOSE: To obtain a molded product of a constant distribution of thickness in a plug-assist pressure-air forming, by designing a plug in such a manner that, when a plastic sheet is drawn by the plug, the whole surface of the former come into close and uniform contact with an outer surface of the latter.
CONSTITUTION: A plastic sheet 17 is drawn by a plug 10 to a terminal insertion position in a female mold 16. A contour of that cross section of the plug 10 which is at right angles to a longitudinal axis 11 thereof and which has the same height 19 as an open end portion 18 of the female mold 16 is in agreement with that of the open end portion 18 of the female mold 16. The size of the contour of the mentioned portion of the plug with respect to the whole circumference thereof is smaller than that of the open end portion 18 of the female mold 16 by a radial distance corresponding to the thickness of the sheet 17. In addition, the diameter of the plug 10 decreases gradually from a rear end portion 15 thereof to a front portion 10-1 thereof. Accordingly, the sheet 17 comes into close and uniform contact with the plug 10. This allows a molded product to have a uniform distribution of thickness.
