Pin construction for two-piece model and system |
摘要 |
A model and die system includes a working quadrant having an upper flat surface. Pin-receiving tapered bores are formed in the upper flat surface and a thin metallic foil covers the bores. Cast teeth are supported by the working quadrant and each cast tooth has at least one tapered pin depending from it. Each pin includes a tapered main body that matches the taper of the tapered bore, a reduced diameter section of the same taper that accommodates torn or ruptured foil, an annular ramp section that sharply crimps the foil about the entry of the tapered bore, and a tapered rim that matches the taper of the tapered bore to lock the pin into its fully seated position.
