Abstract
The utility model provides a material storage die head of plastic machinery with a rotary mechanism, which is characterized in that the top end of the die head is provided with the rotary mechanism, wherein a rotary body of the rotary mechanism is respectively matched with a material storage cylinder cover and a fixed core in a sliding mode. The rotary body and the inner cavity of the material storage cylinder cover can form an annular space, plastic which is arranged in the annular space not only has driving force which is provided by a delivery device but also can be simultaneously driven by the rotary body with a groove to move, thereby, the drawback of the dead corner of the movement of the plastic in the die head is eliminated. The materials and color changing operation can be conveniently and fast carried out by the utility model, and simultaneously, joints existed in traditional parison can be eliminated and the quality of products can be improved.
Description
The utility model relates to the used equipment of a kind of extrusion modling, particularly a kind of parts of extrusion modling device therefor.
Traditional storing die head course of work as shown in Figure 1, extrusion molding material (plastics) 15 is by charge door 11, by spiral extruded material conveying device 12, enter storing die head 14 through import 13, the accumulator 141 of storing die head 14 and die head core 142 all are to be stationary state, plastics 15 enter storing die head 14 from import 13, being bilateral symmetry along the annular space of accumulator 141 and die head core 142 moves, and in seam 151 of the place of catering to of its two side shifting formation, this seam 151 makes the plastic parison section inhomogeneous, influence parts quality, simultaneously, plastics 15 are at the power of pushing that relies on fully from die head 14 foreign sides that moves of annular space, thereby in annular space, easily form the dead angle, those are introduced into the plastics 15 at die head 14 cavity dead angles, will be detained for a long time and can't send from die head 14, consequently cause and reload or during colour changing, must with the material that much renews material or renew color remove to wash the material before changing or change before the material of color, not only cause the waste of materials, while is lost time also, reduces production efficiency.
The purpose of this utility model is that a kind of plastics machinery storing die head with rotating mechanism will be provided, and it can make the parison section even, does not have any lapping defect, and can make materials realize the move mode of first in first out in die head, reach reload or colour changing convenient fast.
Utility model is achieved in that on the top of die head establishes a rotating mechanism, the turn inner chamber that is stretched at the storing cylinder cap of the output of rotating mechanism is and is slidingly matched, the turn external cylindrical surface that is sheathed on fixed core of the output of rotating mechanism is and is slidingly matched, and the inner chamber that the output of rotating mechanism is turned with the storing cylinder cap constitutes an annulus.Send into the plastics of storing die head from spiral extrded material conveying device through import, except according to this extruding power moved in die head, the rotatablely moving of rotating mechanism provided the plastics new power that moves in die head, drive plastics and move in annulus.
The utility model adds rotating mechanism on die head, rotating mechanism gives the interior plastics of annulus with new power, eliminating in traditional die head two sections plastics moves stream and caters to the phenomenon that produces seam, plastics evenly and are promptly moved in annulus and obtain the uniform parison of section, improve parts quality; The motion of rotating mechanism, make in the annulus of die head and no longer have the dead angle, realize the theory structure of materials first in first out in die head, reload or during colour changing in operation, material before the material that renews material or renew color can wash out very soon and renew or change before the color material, save materials, save man-hour, enhance productivity.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a conventional plastic machinery storing die head work schematic diagram.
Fig. 2 is the plastics machinery storing die head and the conveying device configuration schematic diagram of the utility model band rotating mechanism.
Fig. 3 is die head and a conveying device cross-sectional schematic among Fig. 2.
With reference to Fig. 2,3, plastics machinery storing die head 2 is connected with screw conveyor 3 through feed head 31, and the other end of conveying device 3 is connected with feeding funnel 5, and heater 4 is established in conveying device 3 outsides.A rotating mechanism 21 is established on the top of storing die head 2, rotating mechanism 21 by motor 210, decelerator 211, travelling gear 212, turn and 213 form, motor 210 is connected with decelerator 211 through shaft coupling, travelling gear 212 engagement of the driving gear of decelerator 211 and rotating mechanism 21, travelling gear 212 and the output of rotating mechanism 21 are turned and 213 are set firmly and be integral.The output of rotating mechanism 21 is turned and 213 is the cover tubular, its top sets firmly travelling gear 212, its external cylindrical surface is stretched at storing cylinder cap 22 inner chamber upper end holes and is and is slidingly matched, the external cylindrical surface that its inner hole sleeve is located at fixed core 24 is and is slidingly matched, turn and 213 constitute an annulus 23 with the inner chamber of storing cylinder cap 22, turning 213 is stretched on the external cylindrical surface of annulus 23 and offers one group of skewed slot 214, and skewed slot 214 is along circumferential even distribution.
During work, plastics enter the annulus 23 of die head 2 from charging hole 27 through the feed head 31 of conveying device 3 from feeding funnel 5, meanwhile, motor 210 is through decelerator 211 and travelling gear 212, driving turn 213 the rotation, plastics are except the extruding powered with conveying device 31, simultaneously 213 the rotation of turning drive move down moving, turn skewed slot 214 the turn driving function of 213 pairs of plastics of reinforcement then on 213, make the dead angle that in annulus, no longer exists plastics to move, provide section uniform parison, and moving to the space that storing cylinder body 221 and fixed core 24 constitutes slowly, the annular piston of ejection simultaneously 251 drives push rods 25 outer moving, when making, then promote annular pistons 251 by hydraulic cylinder through one group of push rod 25 plastics are extruded outlet 222,26 of control levers are in order to control feed amount.
