Description
Technical field
The present invention relates to injection moulding equipment technology field, refer in particular to a kind of injection molding injection moulding equipment of plastic products polychrome illusion-colour of realizing.
Background technology
The high speed development requirement macromolecule material product of modern consumption electron-like industry has dazzles beautiful colorful outward appearance, to satisfy all ages and classes section consumer demand.The tradition petroleum-based plastics is generally water white transparency or milky, the too dull multi-level design that has limited product of color.The sixties in 20th century, motley plastic products application was opened up in the research application of color masterbatch, and through the development of decades, color masterbatch has entered the stage of a comparative maturity in the application in plastics field.Traditional color masterbatch process is with extruding pelletization after color masterbatch and the plastic raw materials blend, the plastic granule that will have color again carries out the moulding of goods, this process need changes material repeatedly between solid-state and molten state, material property is affected, and processing step is more loaded down with trivial details, production efficiency is low, the energy consumption height, the very flexible of plastic products, the color of changing product if desired also needs to carry out again the compounding of color masterbatch and plastic raw materials, has increased the production cycle.
In addition, because the limitation of equipment, conventional method can't satisfy the disposable injection moulding production requirement of striped goods, more can't realize the moulding of polychrome illusion-colour plastic products.So-called illusion-colour refers to the irregular variation of color, and no obvious color interface has the gradual change mixed effect.
Patent ZL200710194415.7 discloses a kind of coinjection moulding device and hot-runner nozzle thereof.This device uses hot-runner nozzle to guarantee the flowability of melt in manifold, and utilizes the flow direction of the opening and closing control melt between pin and the sleeve, realizes coinjection moulding.This method can accurately be controlled the temperature homogeneity of melt, but its complex structure, the equipment manufacturing cost costliness, the color that can't adjust melt is arbitrarily finished the injection moulding of multicolor plastic goods.
Patent ZL200910005306.5 discloses a kind of mould and method of producing two-color injection-molded parts.Promote to be arranged on sliding die between the first mould piece and the second mould piece by the pressure differential between two kinds of moulding materials, in solidification process, realize the combination of a kind of moulding material and another kind of moulding material.Two runners of mould communicate with corresponding die cavity and have realized the injection moulding of different colours material, but this method can't accurately be controlled the melt flow of each runner and the color of online adjustment goods, and change aberration mold developing again, improved production cost.
Patent ZL201020172998.0 discloses a kind of mixed doubles look injection (mo(u)lding) machine.This equipment cooperatively interacts with the toning oil path block by the first material bar, the second material bar, can realize double-colored material injection moulding colour mixture fade effect.But device fabrication cost height can't satisfy the disposable injection moulding production requirement of striped goods.
Summary of the invention
The object of the present invention is to provide a kind of macromolecular material polychrome calculus illusion-colour injection moulding equipment, so-called calculus injection moulding refers to that melt is through passing through the mixing of " integration type " again in the forming process after the shunting of " differential expression ".This equipment can realize that color masterbatch blend, injection moulding two step process are integrated, accurately control the melt inlet amount of each sprue bush by servomotor, can in production process, arbitrarily adjust the color of plastic products, satisfy the appearance requirement of different colours goods, and can disposable injection moulding have the plastic products of different colours striped.
In order to realize above purpose, the present invention is by the following technical solutions: macromolecular material polychrome calculus illusion-colour injection moulding equipment, mainly by three injection devices and mold closing mechanism, the color matching device, mould is formed, mould is installed between the moving platen of mold closing mechanism and cover half pull, the color matching device is mainly by heater, servomotor, shaft coupling, bearing, the melt distributing shaft, sprue bush, melt distributor with converge nozzle and form, melt distributor is by sprue bush one, sprue bush two, sprue bush three, the melt distributing shaft, converge nozzle, bearing, bearing (ball) cover, melt divides part to form, heater coating melt distributes external or is arranged in melt and divides in the part, distributing shaft links to each other with servomotor by shaft coupling, bearings melt distributing shaft, distributing shaft can divide the part inward turning to change at melt, servomotor can accurately be controlled the rotational angle of melt distributing shaft, sprue bush one, sprue bush two, sprue bush three is connected with the nozzle of three injection moulding apparatus respectively, the installing plate that installation converges nozzle will converge the solid plate of nozzle and installation forming mould, melt divides part to connect, converging nozzle docks with the sprue bush of mould, sprue bush one, sprue bush two, the axis of sprue bush three can be not in one plane, melt divides offers outer flow passage one in the part, outer flow passage two, outer flow passage three respectively with sprue bush one, sprue bush two, the endoporus of sprue bush three communicates, offer inner flow passage one on the melt distributing shaft, inner flow passage two, inner flow passage three and outlet flow, inner flow passage one, inner flow passage two, inner flow passage three communicates with outlet flow, inner flow passage one in the melt distributing shaft rotation process, inner flow passage two, inner flow passage three and outlet flow can with outer flow passage one, outer flow passage two, outer flow passage three and converge the nozzle inner flow passage and be interrupted or communicate continuously, melt flows out through converging nozzle from the melt outlet through the shunting metering back of melt distributing shaft, enters the mould die cavity at last.
Macromolecular material polychrome calculus illusion-colour injection moulding equipment of the present invention, the axis of sprue bush one, sprue bush two, sprue bush three is in a plane and sprue bush one and sprue bush two, three one-tenth 60 ° of layouts of sprue bush two and sprue bush, when servomotor is in original position, the outer flow passage one of sprue bush one correspondence communicates with 1/4th of inner flow passage one, the outer flow passage two of sprue bush two correspondences communicates fully with inner flow passage two, the outer flow passage three of sprue bush three correspondences communicates with 1/2nd of inner flow passage three, converges nozzle and divides the part outlet to communicate with melt.
