Abstract

PURPOSE: To easily and inexpensively manufacture the titled model having complicated features, by relatively displacing a prototype of a vanishing type model against a heated forming body while the prototype is contacted with the forming body, and by shaping passing traces of the forming body on the surface of the prototype to desired shapes.
CONSTITUTION: A prototype 1 of a vanishing type model is fitted to a holding member 10 located at the lower end of screw rod 9, while the screw rod 9 is fitted, and each exposing part 2a'... is heated to a prescribed temperature by supplying an electric current to nichrome wires 2a consisting a forming body 2. When the rod 9 is rotated in the normal direction, the prototype 1 rotates and descends at a prescribed speed, and makes relative displacement while it is contacted with the exposing parts 2a'.... During the course of this relative displacement, a spiral groove 3 is formed on the surface of the prototype 1 by the exposing parts 2a'.... In this way, a vanishing type model 4 having a desired model shape shown by the spiral groove 3 is manufactured from the prototype 1.
