Abstract
The utility model discloses a synchronous double-lead-screw driving device of an injection device of an injection molding machine. The synchronous double-lead-screw driving device comprises a charging barrel fixing template, a moving template and a rear plate, wherein the charging barrel fixing template and the rear plate are fixed through four pull rods; the moving template freely slides between the fixing template and the rear plate through the pull rods; a charging barrel and a screw are fixedly arranged in the middle of the charging barrel fixing template; the tail end of the screw is connected on the moving template; two ball lead screws are arranged on the left and right sides of the rear plate in parallel; nuts of the ball lead screws are connected on the moving template; and gears are respectively arranged at the other ends of the two ball lead screws and are meshed with each other, or are meshed through an intermediate transition gear; and one gear on one side is driven by a motor or each gears is driven by a motor. According to the synchronous double-lead-screw driving device, the synchronous rotation of the lead screws can be guaranteed on a mechanical structure, and the lead screws can be independently driven by the two motors; and moreover, the inertia moment can be reduced, the response speed of the injection molding machine is improved, and the rigidity is high.
Description
Technical field
This practicality relates to a kind of injection structure device of injection machine, specially refers to a kind of mariages thick stick synchronous drive device of injection machine.
Background technology
Can know a kind of injection drive unit by Germany Patent document DE 10351626A1, this injection device is placed on the guiding slide, is made up of barrel fixed form and moving die plate.There is ball-screw the left and right sides of moving die plate secured in parallel respectively, and the nut of leading screw is connected on the barrel fixed form.Tail end at leading screw is connected with synchronous pulley, simultaneously motor is installed on moving die plate, and also fixing synchronous pulley on the motor shaft has a synchronous band to walk around electrical machine belt pulley and two leading screw belt wheels simultaneously, drives two leading screws simultaneously through motor and rotates.Because ball-screw can convert the rotation telemechanical to rectilinear motion, therefore can realize the forward-reverse motion of barrel fixed form and moving die plate.The center fixed of barrel fixed form has barrel and screw rod, and the afterbody of screw rod is connected on the moving die plate.When carrying out action of injection, the barrel fixed form is fixing through connecting rod, therefore can realize forward travel so that moving die plate drives screw rod, and the molten plastic in the barrel is injected mould.The shortcoming of this injection device is that in injection process, parts such as moving die plate, leading screw bearing and motor move all, so ratio of inertias is bigger, influences the response speed of machine; And the barrel fixed form directly is connected through leading screw with moving die plate, and structurally rigidity is bad; Synchronous belt has certain flexible and draftability, can reduce the response speed of machine.If adopt two motors single driving leading screw respectively, can only on electric, carry out the Synchronization Control guide screw movement, can't mechanically keep synchronously, perhaps need extra increase mechanical synchronizer, therefore have the problem of versatility aspect.
Summary of the invention
This practicality provides a kind of injection mariages thick stick drive unit in view of the above problems, makes it on frame for movement, can guarantee driven in synchronism, and has higher rigidity.
This practicality solves the problems of the technologies described above the technical scheme that is adopted:
The mariages thick stick synchronous drive device of injection machine injection device; Comprise barrel fixed form, moving die plate and back plate; Through four pull bars fixedly the barrel fixed form with the back plate; Moving die plate is free to slide between fixed form and back plate through pull bar, in barrel fixed form center fixed barrel and screw rod is arranged, and the screw rod tail end is connected on the moving die plate; Two ball-screws of the parallel installation in the left and right sides at the back plate; The nut of roller leading screw is connected on the moving die plate; Be separately installed with gear at two ball-screw other ends; And these two gears are meshing with each other, and perhaps mesh through the middle transitional gear, adopt the gear of motor-driven one side or two motors to drive two gears respectively.
Owing to be meshing with each other between the gear of two ball-screw two ends or through the transition wheel engagement, therefore can on frame for movement, guarantee the synchronous rotation of leading screw, also available two motors drive separately; Also make the barrel fixed form fixed, thereby reduce the moment of inertia, improve the response speed of injection machine with the back plate, and good rigidly.
Description of drawings
Fig. 1 is the synchronously driven structural representation of the direct gears engaged of this practical embodiment mariages thick stick synchronous drive device.
Fig. 2 is that another embodiment mariages thick stick synchronous drive device of this practicality is through the synchronously driven structural representation of transition gear.
The specific embodiment
With reference to the accompanying drawings this practical embodiment is described.
In Fig. 1 and Fig. 2; Barrel fixed form 2, moving die plate 3, back plate 4 link together through pull bar; Barrel fixed form 2 is fixed together with back plate 4; The two can't relatively move, and moving die plate 3 can advance or retreat slip in that pull bar is cofree, and screw cylinder 1 is fixed on the barrel fixed form 2.
The left and right sides of plate 4 is installed ball-screw 5-1 and 5-2 abreast in the back, and the nut of leading screw is connected on the moving die plate 3 through screw.The other end (left side one end among the figure) at two rhizoid thick sticks is separately installed with gear 6-1 and 6-2, and these two gears are meshing with each other, and motor gear assembly 7-1 meshes with gear 6-1,6-2 respectively with gear among the 7-2 simultaneously.
In structure shown in Figure 1, gear 6-1 and 6-2 directly mesh, and are just changeing a counter-rotating one of when work, so leading screw 5-1 and 5-2 are respectively derotations of a dextrorotation.When rotatablely moving, motor output is delivered on the gear; Though can on software, realize motor synchronous output; But because the hysteresis otherness of electric signal transmission and the difference of motor itself; Can exist the motor output can't be synchronous, certain phase deviation situation is arranged, serious words can cause leading screw asynchronous and kill.And the no gap engagement through gear 6-1 and 6-2 can be guaranteed that leading screw 5-1 and 5-2 rotate simultaneously and makes moving die plate 3 advance or retreat through feed screw nut.The tail end of screw rod is fixed on the moving die plate 3, therefore can realize the molten plastic in the barrel is injected mould.
Also can adopt single motor to drive, thereby realize the driven in synchronism of two rhizoid thick sticks and do not need extra increase servicing unit.
In structure shown in Figure 2, mesh with gear 6-1,6-2 through middle transition gear 8 and to realize synchronously.Because the effect of middle transition gear 8, leading screw be by same direction rotation, so leading screw 5-1 and 5-2 can be identical leading screws.In the driving process, motor also is that equidirectional rotation is exported.
