摘要： PROBLEM TO BE SOLVED: To provide a honeycomb structural body extruding device, facilitating the change of program accompanying the change of configuration of a molded form. SOLUTION: The principal parts of a honeycomb structural body extruding device is constituted of a dice 10 and an extruding mask 20. The extruding mask 20 is formed so as to have an annular shape having an inner diameter D1 and is positioned in the annular notch of the dice 10 formed of the taper surface 19 and a coating material outlet port side end surface 18b of the dice 10. An upper end surface 21, positioned above the extruding mask 20, is formed so as to be abutable against the coating material outlet port side end surface 18b of the dice 10 while the opening areas of material supplying ports 11a, 11b, 11c are controlled by the configuration of the upper end surface 21. In this case, the extruding mask 20 is replaced by another extruding mask 30, shown by two-dotted chain lines, whereby the upper end surface 21 is changed to another upper end surface 31 having a different configuration and, therefore, the opening areas of the material supplying ports 11a, 11b, 11c can be controlled arbitrarily.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a die, by which the meandering of slit grooves can be surely prevented while keeping the soundness of communicating parts to be obtained to supply holes and the slit grooves. SOLUTION: This method is to manufacture the die having the supply holes 4 for material supply and the slit grooves 3 provided, communicating with the supply holes 4. A die stock 10 having groove forming surfaces 11 forming the slit grooves 2 and hole working surfaces 14 providing the supply holes 4 on its front and rear sides, is prepared. The slit grooves 2 are provided on the die stock 10, and shallow holes 40 shorter than the supply holes 4, are provided. Next, by performing noncontact working removing the tip parts 401 of the shallow holes 40, the shallow holes 40 are lengthened and the supply holes 4 are formed.

摘要： PROBLEM TO BE SOLVED: To make it possible to extrude a honeycomb structure having no strain or defect on the cell wall and sheath of an outer periphery. SOLUTION: An extrusion die 10 has a molding part 11 and a supply part 12. The part 11 has a molding groove 111 provided at the extrusion side and a cell wall forming groove 110 made of a guide groove 112 having a width wider than the groove 111 provided at the supply side. The part 12 has a material supply hole 121 communicating with the groove 110 and a material supply hole 122 communicating with a sheath forming passage 113. A straightening plate 30 is engaged with the outer periphery of the part 11, brought into contact with the extrusion side of the part 12, and the inner periphery is brought into close contact with the outer periphery of the part 11 to suppress the flow-out of the material in the groove 112 to the passage 113. Thus, sufficient amount of material is supplied to the part of the groove 111 disposed near the outer periphery of the part 11, and hence the damage of the cell wall near the outer periphery can be prevented.
