Cold flow rubber forming mold

Abstract

The invention provides a cold flow rubber forming mold. The cold flow rubber forming mold comprises a mold upper plate, a mold lower plate, a cooling plate, a heat insulation plate and a heating plate. The cooling plate, the heat insulation plate and the heating plate are successively assembled on an upper end surface of the mold upper plate from top to bottom. The cooling plate, the heat insulation plate and the heating plate are provided with aligned through holes at an injection port of the mold upper plate, and flow guide casing pipes are arranged in the through holes, which means that output ports of the flow guide casing pipes are connected with the injection port of the mold upper plate. An inverted-cone-shaped traction block is arranged at a connecting position of the injection port of the mold upper plate and the output ports of the flow guide casing pipes. By adopting the technical scheme, vulcanization is not performed in a flow channel in a rubber vulcanization process andrepeated recycling is achieved; and waste materials at a sprue position are reduced after mold opening, treatment is simple and convenient, the purposes of saving materials and labor hours are achieved, efficiency is improved, and cost is saved.

Description

technical field [0001] The invention relates to the technical field of mold runners, in particular to a cold flow rubber forming mold. Background technique [0002] At present, the existing molds are used in rubber molding. Since the mold itself has no temperature adjustment ability, it is unavoidable that ordinary injection molds will produce a lot of waste due to vulcanization in the runner after the molding is completed. This requires post-processing, which wastes time and waste. Gum; [0003] In addition, the rubber at the injection port position is prone to tearing gaps during the mold opening process. Contents of the invention [0004] According to the technical problem raised above, a cold flow rubber molding die is provided. The technical means adopted in the present invention are as follows: [0005] A cold flow rubber forming mold, comprising: a mold upper plate and a mold lower plate; [0006] Also includes: cooling plate, heat shielding plate and heating pl...
