Abstract

PURPOSE:To mass-produce seamless hollow products with irregular curvature by extruding, copying the cavity portion with an irregular curvature in a metal mold then cutting into parisons and blowing within this metal mold after coupled the other mating metal molds. CONSTITUTION:A synthetic resin material in a extruding cylinder 3 is pushed out onto the cavity section 7 of a metal mold 6 formed a hollow-pipe. When a motor 14 is drived, a die head 5 is moved right and left or forward and backward and it reaches the curved section of the cavity section 7, each motor is functioned simultaneously and the die head 5 is moved by the shape of the cavity section 7. At high and low positions movement is made by rise and fall of a piston rod 21. Parison is formed by stopping the operation of the pusher 1 and cutting with a cutter 26. The metal mold 6 with the parison is shifted into a clamping device 32 and the paired metal molds 6' are gone down to put the air in the parison and make a hollow formation with an irregular curve by blowing.
