Abstract

PURPOSE:To facilitate the removal of a molded article from the mold by a method wherein a positioning pin is retracted relatively to the mold and the resin molded article being attached to the positioning pin is forcibly separated. CONSTITUTION:After positioning a metallic sleeves 2 in the mold cavity by holding the metallic sleeves 2 at the both ends thereof with posotioning pins 16 and 16' and closing the metallic mold blocks 14 and 14', a resin 3 is injected into the mold. After the resin 3 has been solidified, the mold block 14 is moved rightward by operating the first drive means 34 simultaneously with the mold opening operation to retract the positioning pin 16 relatively to the mold block 14, whereby the positioning pin 16 is separated forcibey from the resin 3. Similarly, the positioning pin 16' is retracted relatively to the mold block 14' by operating the second drive means 34', whereby the positioning (knockout) pin 16' is forcibly separated from the resin 3. The previous separation of the positioning pins from the resin 3 facilitates the removal of the molded article from the mold. This method applies suitably to the manufacture of female connectors used for splicing the insulated wires of communication calbes.
