Background technology
Great majority all are one color product in existing plastic products, and along with the high speed development of society, people's aesthetic standards are also in progressively change, and everybody requires also increasingly high to the color of all types of plastic article.Therefore emerged the dual-color plastic goods on the market, but traditional dual-color plastic goods are normally earlier with after the product injection mo(u)lding of the same colour, the taking-up goods are put into and carry out second kind of color injection molding in the second secondary mould.Because can not guarantee changing to the installation site accuracy that the second secondary mould carries out quadric injection mould, misfit the position during the plastic injection-moulded plastic products to moulding for the first time that often cause second kind of color, forms more substandard products.
Summary of the invention
The utility model is according to the existing practical problem of dual-color plastic article production at present, has proposed a kind of dual-color plastic mould of ability moulding dual-color plastic goods.
The purpose of the utility model can realize through following technical proposal: double-colored car light injection mold; Comprise fixed half and moving half; It is characterized in that dynamic model is provided with the die cavity of two indents, be installed with on the cover half and all can cooperate the die cavity one that is formed for moulding car light plastic products respectively, the punch one and the punch two of die cavity two with two die cavities; On cover half, also offer runner one and runner two; Runner one through cast gate one is communicated with die cavity one, runner two passes through cast gate two and is communicated with die cavity two, the space of described die cavity one is less than the space of die cavity two, above-mentioned dynamic model ability rotated relative to cover half.After dynamic model was set on the injection machine, dynamic model linked to each other with the driving mechanism that can drive the dynamic model rotation.Two runners are connected with two nozzles of injection machine respectively; Be used to carry the plastics of two kinds of different colours; First kind of plastics are in die cavity one after the moulding for the first time; The monochromatic plastic products that form rotate with dynamic model and are positioned at the die cavity two that forms with punch two, and are plastic injection-moulded to the plastic products that in die cavity two, form dichromatism with second kind again.
When adopting technique scheme, the utility model can adopt or combined is used following technical scheme:
Described cover half is provided with cover half push rod and cover half jacking block, and the cover half push rod is slidingly connected in the cover half, and the cover half jacking block is arranged on the punch, and the cover half jacking block is connected on the cover half push rod.The cover half push rod promotes the cover half jacking block makes plastic products and punch be separated.
Described dynamic model is provided with dynamic model push rod and dynamic model jacking block, and the dynamic model push rod is slidingly connected in the dynamic model, and the dynamic model jacking block is arranged on the die cavity place of dynamic model.The dynamic model push rod promotes the dynamic model jacking block makes plastic products and die cavity be separated, and the dynamic model jacking block constitutes the inwall of die cavity in dynamic model one side with the sidewall of dynamic model die cavity.
Described runner one is hot flow path with runner two, and hot flow path can obviously improve the flowability of plastics, improves the quality of products.
Be installed with the control valve of control cast gate one or cast gate two switches on the described cover half, control valve is to be used for controlling cast gate to open or close, and time interval length is that the shot of needs is provided with according to die cavity one and die cavity two injection mo(u)ldings specifically.
Be provided with guide frame between the described fixed half and moving half, described guide frame comprise on the groove that is opened in the flaring on the dynamic model and the cover half can with the frustum of groove fit.
Owing to adopt the technical scheme of the utility model, this double-colored car light injection mold has following beneficial effect: (1) dynamic model can rotate relative to cover half, has reduced the dismounting and the installation of the monochromatic plastic products of moulding for the first time, has improved precision; (2) dynamic model has two identical die cavities, and cover half is provided with two all can cooperate the just different punch of shape and size with die cavity, is convenient on same mould, realize the moulding of dual-color plastic goods like this; (3) have two runners and cast gate on the cover half, can improve the purity of dual-color plastic, avoid plastics to mix, it is attractive in appearance to influence goods.
