PURPOSE: To take off a product without deforming even if a crossing angle of a discharging direction of a molding base and a taking-off direction of a take-off conveyor is slightly large in a method for extrusion molding a hollow inorganic product.
CONSTITUTION: A method for extrusion molding a hollow inorganic product has the steps of extrusion molding a mixing material containing raw material for ceramics as a main raw material S from a molding base 1 having a hollow pin 3, transferring a molded form G to a product pallet 6 while taking OFF the form G by a take-off conveyor 5, and continuously molding it, and comprises the steps of mounting an elastic guide 4 having a length reaching the pallet 6 in the same sectional shape as that of the pin 3 at an end 3A of the pin 3, and extrusion molding it while supplying lubricant to the surface of the pin 3. Thus, deformation of the hollow hole and hence the entire product can be prevented by the guide 4.
