Problems solved by technology
[0002] In the traditional multi-material or multi-color injection molding, it is necessary to set multiple injection stations on the injection molding machine, each injection station is used to inject one type of material, and when one material is injected, the mold is transferred Go to the next station to carry out injection molding of another material, and finally achieve the effect of multi-material injection molding. However, the injection molded product will have problems such as obvious material welding marks, mixed colors, insufficient joint strength, etc., and the work efficiency is low. Production high cost

The invention discloses a multi-material injection molding process. The multi-material injection molding process comprises a machine table and mold preparation process and a glue injection process, wherein the machine table and mold preparation process specifically comprises the steps that an injection molding machine table with a plurality of glue injecting ports is provided, the number of the glue injecting ports corresponds to the number of material types, and mutually independent glue injection ports and flow channels are arranged on a mold according to the number of the material types; and the glue injection process specifically comprises the steps that the glue injecting ports corresponding to the material types on an injection molding machine are butted with the glue injection portsof the mold, the glue injection is carried out at the same time, each glue injecting port is used for conveying one type of material, and the corresponding materials reach preset separation positionsof different materials by controlling glue injection parameters of a glue solution. Since the glue injection is carried out at the same time, the glue solution can maintain high fluidity and temperature when the separation positions are combined, the combination effect of the different materials is good, the structure after combined is high in strength, the injection molding time is shortened, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of injection molding, in particular to a multi-material injection molding process. Background technique [0002] In the traditional multi-material or multi-color injection molding, it is necessary to set up multiple injection stations on the injection molding machine, each injection station is used to inject one type of material, when one material is injected, the mold is transferred Go to the next station to inject another material, and finally achieve the effect of multi-material injection, but the injection molded product will have problems such as obvious material weld marks, mixed colors, insufficient joint strength, etc., and the work efficiency is low. Production high cost. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems in the prior art, and provide a multi-material injection molding process, which can improve product combination eff...
