The invention discloses a double-color synchronous injection mold. The double-color synchronous injection mold comprises an upper mold body and a lower mold body, wherein an upper mold core is arranged on the upper mold body; a lower mold core is arranged on the lower mold body; an injection molding cavity is formed by the upper mold core and the lower mold core; one or more metal partition sheets, a moving mechanism and a temperature control assembly are arranged on the lower mold body; the injection molding cavity is divided into an internal first injection molding cavity and one or more external second injection molding cavities by the metal partition sheets; and a first glue injection port corresponding to the first injection molding cavity and second glue injection ports corresponding to the second injection molding cavities are formed in the upper mold body. Synchronous injection molding is conducted, the temperatures of the metal partition sheets are controlled, glue within a certain range is cooled firstly, then hot melting is conducted on the attaching position of double-color cooled glue and the metal partition sheets, and finally welding is conducted through injection molding pressure, so that the problem of double-color synchronous injection molding can be solved, the machining time is greatly shortened, and the production efficiency is greatly improved.
Description
technical field [0001] The invention relates to the technical field of injection molds, more specifically, to a two-color synchronous injection mold and its method. Background technique [0002] At present, the setting method of two-color injection molds mostly adopts distributed injection molding, that is, injecting glue of one color first, and then changing the shape of the mold and injecting glue of another color after the glue is cooled. Although this method can be produced, there is a processing time. Longer, less productive issues. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-color synchronous injection mold and method for the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] Construct a two-color synchronous injection mold, which includes an upper mold and a lower mold, the upper mold is provide...
