PURPOSE: To prevent deflection from developing in an extruded tubular molded body by a method wherein the tip of a core pin arranged inside a die for obtaining the tubular molded body made of ceramic or the like is projected beyond the tip surface of the die.

CONSTITUTION: The extrusion molding equipment concerned is equipped with a core pin 15 supported by a spider 16 in a die 14, which is equipped with the tip of a cylinder 12. The tip part of the core pin 15 in projected beyond the tip surface of the die 14. When ceramic stock is put in the cylinder 12 and pushed down with a piston 11 under pressure for extrusion, molded body 17 can be prevented from being bent laterally, since the tubular ceramic molded body 17 is supported by the core pin 15 even just after being extruded through the die 14. Further, when the length L of the core pin 15a is made to be longer than 2.0% of the length of the tubular molded body 17, similar effect is realized. Furthermore, in the case of a screw type extrusion molding equipment, by providing a straightening vane just before the die, a bar-like ceramic molded body without void can be obtained.
