Abstract

The invention discloses a forming mold for thick-wall and solid injection products. A movable mold core, an elastic piece and a baffle are sequentially connected in an injection molding cavity and a lengthening cavity. In the injection molding process, the movable mold core is pushed through injection molding pressure, moves horizontally and compresses the elastic piece under restraint of a guide stop dog, a guide sliding pin and a limiting hole; then, the movable mold core squeezes products reversely under the reactive force of the elastic piece, so that pressure exerted on products in the injection molding process is increased, shrinkage cavity caused when the products are formed is avoided, and the product quality is improved. In this way, the products meet the use requirement, and the production cost is reduced. The forming mold for thick-wall and solid injection products embodies the advanced mold design, advanced manufacturing technology and the like.
