Abstract

PURPOSE: To accurately form a permeation pore part such as a window pore or the like to a bottom surface part of a seat frame by a method wherein a recessed part is formed to an upper surface of a male mold and a telescopic body is inserted in said recessed part so as to be freely entered therein and emerged therefrom.
CONSTITUTION: A metal mold 11 is heated to a predetermined temp. as well as a resin strip like piece is heat to a predetermined temp. and said resin strip like piece is placed to a peripheral surface of an upper surface part 14 of a male mold 12, that is, placed in parallel crosses in such a condition that a peripheral side surface of a telescopic body 18 is contacted to peripheral four surfaces thereof in such a condition that said telescopic body 18 is protruded from a recessed part 15 by a spring 19 to be positioned thereto and a female mold 13 is inlaid in the male mold 12 to press the resin strip like piece. By pressing said female mold 13, the telescopic body 18 receives compression load and inserted into the recessed part 15 against a biasing force of the spring 19 and pressed down to a predetermined position of a horizontal mold surface of the female mold 13. Therefore, the resin strip like piece is stretched and spread to be filled in a space between mold surfaces of the male mold 12 and the female mold 13 and a sheet frame 1 is formed.
