The invention discloses a double-color injection molding mold of an automobile sealing strip, which comprises a first mold base and a second mold base, a rotating base block for rotating displacement switching is arranged in the first mold base, two first substrate injection molding mold cores are arranged on the rotating base block, and any first substrate injection molding mold core is provided with a substrate injection molding part and a wrapping glue injection part; a second substrate injection mold core and a wrapping injection mold core are arranged on the second mold base, and a packing part is arranged on the second substrate injection mold core. Through the ejection rotation displacement switching design of the rotary base block, the efficient smoothness and matching stability of switching of double injection molding stations of the mold are met, and the matching precision of secondary molding is greatly improved. The requirement for synchronous forming of the paired workpieces is met, and the relative forming precision of the paired workpieces is unified. According to the injection mold, the base plate injection molding part and the wrapping glue injection part are designed in a matched mode, the same-side double-station molding injection molding requirement is met, the mold cost is reduced, meanwhile, glue injection molding is more uniform, the product injection molding deformation tolerance is reduced, and the product percent of pass is greatly increased.
Description
technical field [0001] The invention relates to a two-color injection mold for automobile sealing strips, belonging to the technical field of injection molds. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to injecting the heated and melted plastic into the mold cavity under high pressure from the injection molding machine, and after cooling and solidifying, a molded product is obtained. [0003] At present, there is a kind of automobile sealing strip, which includes the main body of the sealing strip substrate and the raised ribs arranged on the main body of the sealing strip substrate. Several through-holes are provided, and the main body of the wrapped injection-molded body and the sealing strip substrate is two-col...
