Technical field
The utility model relates to a kind of injection device, is specifically related to a kind of special-purpose injection device of injection machine that is used for the marbling plastic products, belongs to the injection machine technical field.
Background technology
Injection machine is the equipment that is used for mould of plastics is carried out injection mo(u)lding; The course of work of injection machine is earlier powdery or granular plastic raw materials to be joined in the machine barrel; Rotation and the heater on the machine barrel through screw rod make plastic raw materials become molten condition, then in official hour with the molten condition plastic raw materials of specified quantity, through nozzle with certain pressure and speed injection in mold cavity; After injection is accomplished; The molten condition plastic raw materials that enters into mold cavity keeps, cools off through the pressure of certain hour again, make its curing molding, but just goods is taken out in die sinking.
Present injection machine can be divided into monochromatic injection machine and double coloured plastic injection machine two big classes by its function, and double coloured plastic injection machine can be divided into colour mixture injection machine, interlayer injection machine, clear double coloured plastic injection machine etc. again.Traditional monochromatic injection machine is because the reasons in structure of its injection device; Can only the manufacture order colour product; If when using traditional monochromatic injection machine to produce double-colored goods; After the plastic raw materials of color gets into barrel more than 2 kinds, by the screw rod that rotates powdery or granular plastic raw materials are pushed and to be travelled forward, screw rod rotates the heat that produces makes the plastic raw materials in the barrel be melted into glue; And under the screw acting that rotates, mixed equably and become a kind of color, can't produce the marbling plastic products of forming by multiple color decorative pattern.
And traditional double coloured plastic injection machine production is when having marblized multicolor plastic goods, and production must could realize by two or three injection devices, therefore makes the injection machine complex structure, manufactures trouble, and the complete machine cost is higher, and complex operation.
Summary of the invention
The purpose of the utility model is: provide a kind of simple and reasonable, easy and simple to handle; Manufacturing cost is low; Must could realize the special-purpose injection device of the injection machine that is used for the marbling plastic products of multicolor plastic production of articles by two or three injection devices to solve traditional double coloured plastic injection machine.
The utility model is to realize above-mentioned purpose through following technical scheme:
A kind of special-purpose injection device of injection machine that is used for the marbling plastic products; It is made up of barrel, injection screw, water recirculator and nozzle head, it is characterized in that: barrel is provided with the barrel inner chamber, and the barrel front end is provided with the nozzle body that communicates with the barrel inner chamber; Nozzle body is provided with nozzle head; Be provided with injection screw in the barrel inner chamber, an end of injection screw extends to the outside, barrel rear end, is provided with spreader in the barrel inner chamber of the injection screw other end; The outer wall of barrel is provided with water recirculator; The barrel of water recirculator one side is provided with the charging aperture that communicates with the barrel inner chamber, and the interval shape is provided with electric heater A, electric heater B, electric heater C and electric heater D on the barrel of water recirculator opposite side, and nozzle body and nozzle head are respectively arranged with electric heater E and electric heater F.
Described spreader is the cylinder that spins fusiformis, is symmetrically arranged with through hole on the circumference of spreader.
The beneficial effect of the utility model is:
This special-purpose injection device of injection machine that is used for the marbling plastic products is simple and reasonable; When production has marblized multicolor plastic goods; Get into the polychrome raw material in the barrel inner chamber by charging aperture, push down through the screw rod that rotates and travel forward, under the effect of water recirculator; The screw rod that polychrome raw material in the barrel inner chamber is rotated evenly mixes but can not melt; Push the polychrome raw material that constantly gets into metering section down at screw rod and receive the effect of electric heater A to be melted into glue, the while is expelled in the mould through nozzle head by the through hole of spreader under screw rod is constantly pushed, in this process; Melt jellied polychrome raw material under the synergy of electric heater B, electric heater C and electric heater D, electric heater E and electric heater F; Remain molten, and under the effect of spreader the change at random color, final production goes out the color interface and clearly has marblized multicolor plastic goods.This special-purpose injection device of injection machine that is used for the marbling plastic products is easy and simple to handle, and manufacturing cost is low, has solved traditional monochromatic injection machine because the reasons in structure of its injection device; Can only the manufacture order colour product; And traditional double coloured plastic injection machine production is when having marblized multicolor plastic goods, and production must could realize by two or three injection devices, makes the injection machine complex structure; Manufacture trouble; The complete machine cost is higher, and the problem of complex operation, is specially adapted to produce the marbling plastic products of being made up of multiple color decorative pattern and uses.
