Abstract

Improvements in molds for injection molding of thick-walled parts, of the type comprising at least one internal molding cavity called impression, and a supply channel, said supply channel being in connection on the one hand with said impression and on the other with the exterior, for coupling to a molding material injection unit, characterized in that the feeding channel ends in said impression by a cylindrical sector, and in that a stem with a complementary section to that of the said sector is mobile mounted on the axis of said sector, between a backward position where it is totally outside said sector and an advanced position where it is adjusted without play in said sector.
