Mould for the manufacture of pieces of thermoplastic material

Abstract

Abstract The invention contemplates mold tooling adapted for the molding of a variety of thermoplastic parts. The mold comprises two die elements which carry die-insert plugs, and the mutually facing surfaces of these plugs determine the shape of the part to be produced. In order to retain the insert plugs (3, 4) in the die elements (1, 2) in such manner that they can be simply and easily replaced, that surface (7, 8) of an insert plug (3, 4) which faces its supporting die element (1, 2), and that surface (5, 6) of the supporting die element (1, 2) which serves to receive the involved insert plug (3, 4), are developed as polished spherical surfaces of the same radius RN. Each interchangeable insert plug has a spherical seating surface of the same spherical radius RN.
