Device structure of the present invention is as follows:
As shown in Figure 1: 4 is frame, and frame 4 can adopt shaped steel welding production or casting.Above an end of frame 4, injection seat 3 is installed, is provided with slideway between injection seat 3 and the frame 4.Injector 1 is bolted on the injection seat 3.Injection seat 3 connects the oil cylinder that joins with hydraulic control device, and the work of oil cylinder can drive injection seat 3 along frame 4 longitudinal sliding motions, has driven injector 1 horizontal direction simultaneously and has moved.This part structure is a prior art, no longer describes in detail.
Shown in Fig. 1～7: bolt is connected with fixed platform 8 on the frame 4, is equipped with to drive the lowering or hoisting gear that patrix 14 moves up and down above fixed platform 8, and a side of fixed platform 8 is provided with hoistable platform 9, and opposite side is provided with lifting moving platform 18.
Wherein driving the lifting device structure that patrix 14 moves up and down is: be fixed on the fixed platform 8 with the bottom head of nut with guide pillar 25, and make guide pillar 25 be the vertical setting.On upper guide post 25, be set with along the upper guide post 25 patrix moving body 13 that can slide up and down, described patrix 14 is installed on the bottom surface of patrix moving body 13 by screw, be positioned on the top upper guide post 25 of patrix moving body 13 and be fixed with top board 12 with nut, so that the Mode-locking oil cylinder 27 that joins with hydraulic control device to be installed on the position, the piston rod external end head that matches with Mode-locking oil cylinder 27 and patrix moving body 13 are fixedlyed connected by screw in the top board 12.During Mode-locking oil cylinder 27 work, can move up and down along guide pillar 25 by its piston rod drive patrix moving body 13 and patrix 14.
The both sides that two Mode-locking oil cylinders 26 lay respectively at Mode-locking oil cylinder 27 also are installed, to improve its locked mode ability between top board 12 and patrix moving body 13.
The demoulding oil jar 28 and the ejector spring 29 that join with hydraulic control device are installed between patrix moving body 13 and the patrix 14, when moving the demoulding on the patrix 14, can successfully throw off with the moulded products of counterdie and Qi Nei.
Described hoistable platform 9 structures are: hoistable platform 9 is sleeved on the guide pillar 7, with respect to guide pillar 7 slidably.Guide pillar 7 is fixedly mounted on the frame 4 along vertical by nut, in the bottom of frame 4 bolting the oil cylinder 6 that joins with hydraulic control device is arranged, and the termination of the piston rod that matches with oil cylinder 6 adopts ring flange to fixedly connected with the bottom surface of hoistable platform 9.When oil cylinder 6 work, can drive hoistable platform 9 by the piston rod that matches with oil cylinder 6 and move up and down along guide pillar 7.When hoistable platform 9 rises to top dead centre, just concordant with intrinsic fixed platform 8, above it with the top coplane of fixed platform 8.
Described lifting moving platform 18 structures are: be fixed with guide pillar 22 with nut on the frame 4, guide pillar 22 is along the vertical setting, the oil cylinder 24 that joins with hydraulic control device is bolted to the bottom inside of frame 4, fixedlys connected by flange between piston rod 23 terminations that match with oil cylinder 24 and the crane.Crane is sleeved on the guide pillar 22.Bolting has the horizontally disposed oil cylinder 21 that joins with hydraulic control device on the crane, the piston rod 20 that matches with oil cylinder 21 connects lifting moving platform 18 by connecting plate 19, lifting moving platform 18 be located on the crane and and crane between for being slidingly connected.Be fixed with the oil cylinder 17 that joins with hydraulic control device on lifting moving platform 18, be connected push and block piece 16 with the piston rod end screw that oil cylinder 17 matches, push and block piece 16 is slidingly connected on the lifting moving platform 18.Described being slidingly connected is the chute type connected mode.When oil cylinder 24 work, but piston rod 23 drive cranes, oil cylinder 21, hoistable platform 18, oil cylinder 17, the push and block piece 16 that can lead in it move up and down along guide pillar 22 together, when moving to top dead centre, hoistable platform 18 top just with the top coplane of fixed platform 8; When oil cylinder 21 work, can drive mobile platform 18 by the piston rod in it 20, connecting plate 19 and move horizontally along crane, the oil cylinder 17, the push and block piece 16 that drive simultaneously on it move together; When oil cylinder 17 work, can drive push and block piece 16 along 18 horizontal slips of lifting moving platform by the piston rod in it.When hoistable platform 9 and lifting moving platform 18 drop to lower dead center simultaneously, just be on the same horizontal plane above it.
As shown in Figure 8: described injector 1 head place is provided with buffering force application spring 31, and spring 31 is sleeved on the core bar 30, and core bar 30 is fixed on the below of the nozzle 2 at head place.When aligning the injection port of counterdie,, can play cushioning effect, in injection process, also play the effect that leans counterdie simultaneously because the existence of spring 31 is arranged when injector 1 reach and with nozzle 2.
The course of work is as follows:
Each oil cylinder all joins by fluid pressure line and valve and hydraulic control device.As Fig. 2: second counterdie 10 and the 3rd counterdie 15 are positioned on the fixed platform 8 when starting working, hoistable platform 9 and lifting moving platform 18 all are in top dead center position, second counterdie 11 is positioned at long falling on the platform 9, patrix moving body 13 and patrix 14 are positioned at top dead center position, injection seat 3 drives injector 1 reach under hydraulic oil cylinder driving, make nozzle 2 align the injection port of first counterdie 11, and promote first counterdie 11 and move to right and lean second counterdie 10 and the 3rd counterdie 15, first counterdie 11 and second counterdie 10 are positioned on the fixed platform 8, the 3rd counterdie 15 claims moving to lifting moving platform 18, and lean against on the push and block piece 16, spacing by oil cylinder 17 and push and block piece 16.Mode-locking oil cylinder 26,27 work then make patrix moving body 13 drive patrix 14 and move down, with first counterdie, 11 matched moulds and locked mode, through the inner chamber injection of plastic material forming (as shown in Figure 3) of nozzle 2 between the patrix and first counterdie 11.
As shown in Figure 4: after the injection, injector 1 travelling backwards, Mode-locking oil cylinder 26,27 work, band transports on the mould 14 and moves, oil cylinder 24 work, drive crane, the 3rd counterdie 15, push and block piece 16, oil cylinder 17,, lifting moving platform 18, oil cylinder 21 move down along guide pillar 22 together.Oil cylinder 6 work simultaneously drive hoistable platform 9 and move down.Make hoistable platform 9 and lifting moving platform 18 be in bottom dead center position simultaneously.
As shown in Figure 5: when moving to lower dead center, oil cylinder 21 work drive lifting and claim moving platform 18 to move to left, and are merged into a platform and integrally with hoistable platform 9.This moment, oil cylinder 17 work utilized push and block piece 16 that the 3rd counterdie 15 is pushed on the hoistable platform 9, and hoistable platform 9 rises to top dead center position (as shown in Figure 6) then.Hoistable platform 18 these assemblies are driven by oil cylinder and move on to top dead centre.
When mold cavity is injected raw material down to one of them, with injection port on another counterdie that it leans on mutually just with injected counterdie on outlet relative, the raw material that makes injection is connected as a single entity the goods of double injection moulding, form continuous plastic products, repeat above-mentioned action repeatedly, can produce continuous plastic products.After the moulding, can be by wrap-up 5 with its rolling rolling.Wrap-up 5 can rotate realization by the winding stand that driven by motor is supported on the support.
