Abstract
The multiple material multicolor and no glue canal forming process features that inside one double material injection molding machine with one set of two layer laminated mold and one middle mold plate mechanism capable of reciprocating by 180 deg, twice injection moldings are completed before and after the middle mold plate is turned by 180 deg. The process can form injection molded product with different colors in different sides or different layers, and has the advantages of capacity of ensuring required product appearance and shrinkage, high product quality, high production efficiency, etc.
Description
Technical field
The present invention relates to a kind of injecting products, especially a kind of multiple-materials multicolor glue path-free shaping technique.
Background technology
Product appearances such as current automobile, motorcycle light fixture electrical equipment are circular or square to whole abnormal shapeization development by former single rule, End-Customer requires more and more higher to product appearance, optical signal integrations such as steering indicating light lens, brake lamp lens, answer inverse device appear in many medium and high-grade automobile and motorcycle light fixtures, and existing this type of production domesticization product relies on twice, three times processing to realize substantially.Reduce through the product quality qualification rate after the processing repeatedly, influence product structure firmly, overall performance reduces, produce more Jiao Kou and expect that the increase of material returning work operation has improved product cost, has reduced product quality and has also reduced production efficiency.Many material mold need to rotate in the course of work, so the requirement of mould design and injection machine is more accurate.In addition, because the changeability of many materials injection moulding is very high, produce smoothly so will reach, it is desirable to meet expection, the design of all mould must consider synchronously with product design, and the existing pair of material injection machine specification and disunity, and the problem of considering when causing the mould design is more
Summary of the invention
At above-mentioned existing problems, the invention provides a kind of multiple-materials multicolor glue path-free shaping technique, adopt reasonable process to carry out technological adjustment, can improve the quality and the qualification rate of product, have better appearance simultaneously.
For reaching above purpose, the present invention by the following technical solutions, a kind of multiple-materials multicolor glue path-free shaping technique, it is characterized in that utilizing two material injection machines, the two-layer stack mould of a cover, and the intermediate die plate device can do 180 ° back and forth the mechanisms of rotation carry out, when injection machine is carrying out the injection moulding first time, die sinking after cooling off; Intermediate die plate makes horizontal by design or rectilinear direction is rotated 180 °, and first moulding of attached work in core rod is diverted to second layer die cavity, carries out common injection moulding operation behind the matched moulds again, and the first time of this mode and injection moulding for the second time are synchronous injection moulding forms.
The invention has the advantages that to compare with former technology and have the following advantages through the production technology after improving:
(1) to the product of the different plastics colors of face about ectonexine, can replacing repeatedly, processing changes one-shot forming into.
(2) guarantee that product appearance and product shrink requirement.
(3) adopt many materials injection mold mode after reducing the operation process, must improve functional, the aesthetics and the steady quality of product.Raising the efficiency more than 50% than traditional injection moulding mould on injection time, reducing substandard products or waste product loss more than 20%.
The specific embodiment:
Embodiment one
A kind of multiple-materials multicolor glue path-free shaping technique, it is characterized in that utilizing two material injection machines, the two-layer stack mould of a cover, and the intermediate die plate device can do 180 ° back and forth the mechanisms of rotation carry out, when injection machine is carrying out the injection moulding first time, die sinking after cooling off; Intermediate die plate makes horizontal by design or rectilinear direction is rotated 180 °, and first moulding of attached work in core rod is diverted to second layer die cavity, carries out common injection moulding operation behind the matched moulds again, and the first time of this mode and injection moulding for the second time are synchronous injection moulding forms.
Embodiment two
With a kind of multiple-materials multicolor glue path-free shaping technique of embodiment one, its difference is to utilize loose core of oil cylinder that injection position is positioned, and can inject different positions when utilizing microcomputer control loose core of oil cylinder deciliter state, and the conversion injection point reaches repeatedly injection moulding.
Embodiment three
A kind of multiple-materials multicolor glue path-free shaping technique with embodiment one, its difference is to utilize hot flow path technology injection material to keep melt temperature in injection process, and utilize temperature control system to control inner injection moulding temperature of charge, satisfy the injection moulding requirement, utilize temperature control system control mould inside oil temperature simultaneously, utilize oil to come cooling products, guarantee that product appearance and product shrink requirement.
Embodiment four
A kind of multiple-materials multicolor glue path-free shaping technique with embodiment one, its difference is that mould uses the design of symmetrical dimorphism chamber, screw rod carries out twice injection moulding (once and utilize between the secondary to loose core change the injection moulding position) rotation by mould symmetry on molding machine again, change the injection moulding position once more and carry out three, four injection mouldings, this process at first needs the cooperation of mould symmetry rotating mechanism, relies on computer to control the time-temperature and the pressure of repeatedly segmentation injection moulding simultaneously.
Embodiment five
A kind of multiple-materials multicolor glue path-free shaping technique with embodiment one, its difference is by lengthening screw in injection molding machine nozzle, injection is to allow nozzle directly stretch into mould carry out injection moulding, has solved original cold burden and cold burden that produces with the runner injection moulding and has entered the material line that the shape chamber produces.And stopped the Jiao Kou material substantially, the material utilization rate has reached more than 99.8%, and single product is using this technology can reduce material cost more than 5%.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
