Abstract

PURPOSE:To obtain the extruding die having many pores, easy to clean and of low cost by a method wherein the desired number of grooves is cut on the surface of platelike materials and several these materials are heapted into a unitary body. CONSTITUTION:On the surface of a platelike material 2 the desired number of extruding guide grooves 7 having any shape is cut, the paltelike materials 2 are inserted in a frame 3 and clamped by clamp bolts 4 on both sides into a unitary body. Since the extruding guide grooves 7 are made by cutting operation, even small pores having a diameter of about 0.6mm. can be shaped easily and inexpensively because drilling is not used. When a connecting groove 8 is formed on the contact surface 6 so as to connect the guide grooves 7 with one another, the pressure of molten resin at P1, P2 can be equalized. The guide grooves 7 of 0.6mm. or less which are difficult to drill by a usual method can be manufactured very easily. This method is particularly available for blow extrusion molding that sudden blow and expansion are generated after extrusion. As disassembly to parts is easy, cleaning of the grooves is easy, too.
