Die structure: structure of double color molding die and mould has bigger difference, mainly, the mold has two sets of gating system and two - cavity, and core transposition mechanism, in addition to launch requirements are also different from the ordinary injection mold.
1.core back its structure characteristics of double color injection mold in an injection, the core does not retrocede, two injection by the core back second color space forming part of the structure of the seat, back core of general shape is simple and relatively low, should not be used with more complex insert double color plastic molding.
2.off the rotary plate double injection mold is characterized with a rotating mechanism, the injection molding machine requirements are relatively low, applicable to small and medium-sized dual color mode of plastic parts production.
3.The rotating mandrel type two-color injection mold is characterized by double color injection rotating mode, requires a rotating disc special injection molding equipment, more accuracy is required for injection molding machine.
4.The slide core type two-color injection mold is characterized by the use of large pieces of production, the need to set up mobile mechanism in mold and injection molding machine expert.
