The specific embodiment
Below in conjunction with drawings and Examples, the utility model is elaborated.
Consult Fig. 2, Fig. 3, and Fig. 4, a preferred embodiment of the utility model injection apparatus for continous formation comprises a feed unit 2, injection unit 3, four die holder unit 4, a control valve unit 5, and a control device 6.
This feed unit 2 comprises that the mixing feeding machine of CD-ROM drive motor 23 that a discharge nozzle 21, one can be placed in rotationally screw rod in this discharge nozzle 21 22, one and drive this screw rod 22,24, one are communicated with the conveyer belt 26 that the storage extrusion barrel 25 of this discharge nozzle 21, are connected in this mixing feeding machine 24 and 25 of this storage extrusion barrels, reach a conveying worm 27.Wherein, this mixing feeding machine 24 can be in order to be uniformly mixed plastics in the form of sheets, and be sent in this storage extrusion barrel 25 by this conveyer belt 26, deliver to again in this discharge nozzle 21 and carry out after heating and melting becomes liquid molten plastic, rotating and action that molten plastic is pushed forward to relend by 22 rotations of this screw rod.And this conveying worm 27 can be quantitative the conveying pulverized limestone in this storage extrusion barrel 25 with slice plastic carry out batch mixing.
This injection unit 3 comprises a storing pipe 31, and an actuator 32 that shoots material that is connected in this storing pipe 31.
This storing pipe 31 have one with this discharge nozzle 21 main leg 311 of straight lines altogether, and two inferior pipeline sections 312 that are connected to 4 of this main leg 311 and aforementioned die holder unit, wherein, this main leg 311 is connected and presents T-shaped aspect with this pipeline section 312.
This actuator 32 that shoots material has the interior body of rod 321 of this main leg 311 that can be placed in movably this storing pipe 31, and a cylinder pressure 322 that drives this body of rod 321 to move.
Each die holder unit 4 comprises one, and fixedly die holder 41, an energy are with respect to this mobile die holder 42 that fixedly die holder 41 moves around, and one drive this to move the die holder actuator 43 of die holder 42.This die holder actuator 43 has a connection, and this moves the body of rod 431 of die holder 42, and the cylinder pressure 432 of this body of rod 431 of interlock.Wherein, the non-the utility model technical characteristics in this die holder unit 4, therefore do not repeat in detail at this.
This control valve unit 5 comprises the main switching valve 51 of 31 of this main leg 311 who is connected in this discharge nozzle 21 and this storing pipes, and the inferior switch valve 52 of 312 of aforementioned pipeline sections of four aforementioned fixedly die holders 41 that are connected to aforementioned die holder unit 4 and this storing pipe 31.
This main switching valve 51 comprises that a tube body that is connected in 31 of this discharge nozzle 21 and this storing pipes 511, one are placed in the conducting element 512 of this tube body 511 and similar arrow profile, a moving member 513 that is placed in this tube body 511 and can be sheathed on movably these conducting element 512 1 ends, and one is sheathed on these conducting element 512 tail ends and between the ring set 514 of 22 of this conducting element 512 and this screw rods.Wherein, the external diameter of this moving member 513 slightly equals the internal diameter of this tube body 511 and has an oblique anchor ring 5131 that is intended for this ring set 514, and this ring set 514 has a scalene cone 5141 that is intended for this oblique anchor ring 5131.Wherein, when this main switching valve 51 is opened, this oblique anchor ring 5131 is separated with this scalene cone 5141, molten plastic can flow to this storing pipe 31 via this oblique anchor ring 5131 and 5141 of this scalene cones, when this main switching valve 51 is closed, this oblique anchor ring 5131 is connected with this scalene cone 5141, and molten plastic is by block and can't be via this oblique anchor ring 5131 and 5141 outflows of this scalene cone.
This control device 6 comprises a controlled processing unit 61 that is electrically connected on respectively aforementioned switch valve 52 and this CD-ROM drive motor 23.This controlled processing unit 61 can input program, in order to control the sequence of movement of aforementioned switch valve 52, allows injecting in aforementioned die holder unit 4 that molten plastic can gradation.
In start, when plastics store extrusion barrel 25 this discharge nozzle 21 of inflow by this, this CD-ROM drive motor 23 drives these screw rod 22 rotations to move toward this main switching valve 51 to drive molten plastic, now, because the pressure of this discharge nozzle 21 is greater than this storing pipe 31 pressure, so, molten plastic can promote this moving member 513, and allow this oblique anchor ring 5131 of this moving member 513 be separated with this scalene cone 5141 of this ring set 514, so, this main switching valve 51 is to be positioned at opening, as shown in Figure 4, and this discharge nozzle 21 is connected with this storing pipe 31, therefore molten plastic can be flowed in this storing pipe 31 by this discharge nozzle 21, as shown by the arrows in Figure 4, and when molten plastic is squeezed into this storing pipe 31 by this screw rod 22, this body of rod 321 of this actuator 32 that shoots material is toward moving away from this main switching valve 51, to allow molten plastic be stored in this storing pipe 31, as shown in Figure 5.
When this injection unit 3 wants to be shot material action, this CD-ROM drive motor 23 stops and not driving this screw rod 22 and rotate, this body of rod 321 of this actuator 32 that shoots material gradually moves to forward and penetrates molten plastic fully, as shown in Figure 7, and this body of rod 321 forward gradually in mobile process the pressure of this storing pipe 31 be greater than the pressure of this discharge nozzle 21, therefore allow this moving member 513 move and to allow this oblique anchor ring 5131 be connected with this scalene cone 5141 toward these ring set 514 directions, as shown in Figure 6, this is the state that this main switching valve 51 is closed, its molten plastic can not be back in this discharge nozzle 21, and at the same time, this controlled processing unit 61 is controlled one of them switch valve 52 and is opened, to allow molten plastic pour into one of them die holder unit 4 by this storing pipe 31, to complete this ejection formation action.The person of connecing, this switch valve 52 cuts out again, and this CD-ROM drive motor 23 is opened again with this main switching valve 51, to repeat again above-mentioned action.Thus, can gradation molten plastic be injected in aforementioned die holder unit 4, and first carry out this die holder unit 4 of ejection formation, can first feeding, and carry out again the ejection formation action of lower a time, and thus, can be within the unit interval, reach the comparatively ejaculation product of volume, to promote production capacity.
In sum, the utility model injection apparatus for continous formation has following advantages and Gong Xiao ︰
Utilize the design of aforementioned die holder unit 4 and this control valve unit 5, allow molten plastic gradation inject in aforementioned die holder unit 4, and be different from background technology described, only there is a die holder unit 4, and need after plastic cool is taken out product, could carry out again ejection formation next time, so the utility model can be produced more product within the unit interval, its production efficiency is better.
