PURPOSE:To provide an injection molding equipment capable of efficiently molding a molded form, in which the quantity of one molding material in two kinds or more of molding materials is made smaller than that of the other. CONSTITUTION:In this invention, an auxiliary injector 2 injecting an auxiliary material is arranged in the rectangular direction to a main injector 1 injecting a main material and a main sprue 11, and the auxiliary injector 2 and an auxiliary sprue 24 are connected by a hot runner 22. A small cavity B is formed by a movable member 3 projected and retreated and driven to and form the cavity A of molds 3, 4 at a position oppositely faced to said auxiliary sprue 24, and the auxiliary material is injected into the small cavity B from the auxiliary sprue 24. |
