Abstract

The invention discloses a temperature synchronous control method for hot runners of an injection molding multi-mold-cavity mold, relates to the technical field of an injection molding multi-mold-cavity mold, and aims at solving the problem of poor injection molding effect caused by difference and desynchrony of the hot runner temperature in the use process of an existing injection molding multi-mold-cavity mold. Four mold cavities are formed inside the mold, and in addition, the mold cavities and the mold are of an integral structure; a first cooling pipe is arranged outside the mold; four first hot runners are arranged at one side of the mold cavity; a flow division disc is arranged at one ends of the first hot runners; a second hot runner is arranged at one side of the flow division disc; two temperature control covers are arranged outside the second hot runner; the temperature control covers are detachably connected with the second hot runner; and the front end surface of each temperature control cover is provided with screw bolts.

Description

technical field [0001] The invention relates to the technical field of injection multi-cavity moulds, in particular to a method for synchronously controlling the temperature of hot runners of injection multi-cavity moulds. Background technique [0002] Injection molding is a method of producing industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method. Injection molding machine (referred to as injection machine or injection molding machine) is a thermoplastic or thermosetting material. The main molding equipment that uses plastic molding molds to make plastic products of various shapes. Injection molding is realized through injection molding machines and molds. Molds are used in industrial production for injection molding, blow molding, extrusion, die-casting or forging molding, and smelting , stamping and other methods to obtain various ...
