Abstract
A kind of vertical compression type mould closing mechanism; head plate (1) and tailgate (5) are fixed in frame; slide rail (3) is installed between head plate (1) and tailgate (5); moving die plate (2) reciprocally movement to be installed on slide rail (3) upper and be connected with push rod (9); it is secondary that ball screw (4) and push rod (9) form screw nut driving; servomotor (6) and belt gear (8) connect, and belt gear (8) and ball screw (4) connect.Its advantage is out that the speed of mould assembling action is fast, positional precision improves, and ensure that the accurate of template motion thrust, controls the template offset deviation that produces of inertia at the volley, makes low pressure mould protect the reliability of This move and response accuracy greatly to improve.Meanwhile, open and touch and eject action and can synchronously carry out, achieve " die sinking-eject " composite move that general fluid pressure type injection machine cannot realize, save the time ejecting action.
Description
[technical field]
The utility model relates to model and opens, closes or clamping device, espespecially a kind of vertical compression type mould closing mechanism.
[background technology]
The Clamping Device of Injection Moulding Machine of prior art all adopts five-point type hydraulic mould-matching mechanism, and stressed unfavorable to template of this structure, makes template have bending tendency., clamp force high in injection pressure is high, makes template long-term work in flexural deformation, seriously affect service life.Meanwhile, machine hinge machine stressed member is many, and As time goes on, wearing part is many, and it is uneven to wear and tear, and can not ensure Product Precision.This five-point type machine hinge Standard difficulty of prior art is comparatively large, and easily produce larger error in assembling process, thus had a strong impact on the repetitive positioning accuracy of clamping mechanism, this is its shortcoming.
[summary of the invention]
For the shortcoming of prior art, the purpose of this utility model is to provide a kind of vertical compression type mould closing mechanism.
The utility model solves the technical scheme that its technical problem adopts: provide a kind of vertical compression type mould closing mechanism, it is characterized in that: comprise a plate, tailgate, moving die plate, slide rail, push rod, servomotor, motor connecting plate, ball screw and synchronizing wheel transmission mechanism, described head plate and tailgate are fixed in frame, between head plate and tailgate, slide rail is installed, moving die plate being reciprocally installed on slide rail and being connected with push rod of movement, it is secondary that ball screw and push rod form screw nut driving, servomotor with synchronizing wheel transmission joint, synchronizing wheel transmission mechanism and ball screw connect, servomotor is installed on motor connecting plate, motor connecting plate is fixed in frame.
Servomotor drives belt gear running thus drives ball screw running, and ball screw promotes push rod and template, template is moved as linear reciprocation along slide rail, thus realizes the opening and closing mould of injection machine
.
The utility model adopts vertical compression type mould-locking structure; wherein ball screw and Clamping System are rigidly connected; ball screw is driven by servomotor; make out the also corresponding raising of the speed of mould assembling action, positional precision; ensure that the accurate of template motion thrust; control the template offset deviation that produces of inertia at the volley, make low pressure mould protect the reliability of This move and response accuracy greatly to improve.Meanwhile, open and touch and eject action and can synchronously carry out, achieve " die sinking-eject " composite move that general fluid pressure type injection machine cannot realize, save the time ejecting action.
The beneficial effects of the utility model are: the speed opening mould assembling action is fast, positional precision improves; ensure that the accurate of template motion thrust; control the template offset deviation that produces of inertia at the volley, make low pressure mould protect the reliability of This move and response accuracy greatly to improve.Meanwhile, open and touch and eject action and can synchronously carry out, achieve " die sinking-eject " composite move that general fluid pressure type injection machine cannot realize, save the time ejecting action.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the axle of Fig. 1 surveys view schematic diagram.
Fig. 3 is the E portion enlarged diagram of Fig. 1.
In figure: 1 be head plate, 2 be moving die plate, 3 be slide rail, 4 be ball screw, 5 be tailgate, 6 be servomotor, 7 be motor connecting plate, 8 be belt gear, 9 for push rod.
[detailed description of the invention]
See accompanying drawing, a kind of vertical compression type mould closing mechanism of the utility model, comprise a plate 1, tailgate 5, moving die plate 2, slide rail 3, push rod 9, servomotor 6, motor connecting plate 7, ball screw 4 and belt gear 8, described head plate 1 and tailgate 5 are fixed in frame, slide rail 3 is installed between head plate 1 and tailgate 5, moving die plate 2 being reciprocally installed on slide rail 3 and being connected with push rod 9 of movement, ball screw 4 and push rod 9 form screw nut driving pair, servomotor 6 and belt gear 8 connect, belt gear 8 and ball screw 4 connect, servomotor 6 is installed on motor connecting plate 7, motor connecting plate 7 is fixed in frame.
Servomotor 6 drives belt gear 8 to operate thus drives ball screw 4 to operate, and ball screw 4 promotes push rod 9 and template 2, and template 2 is moved along slide rail 3 as linear reciprocation, thus realizes the opening and closing mould of injection machine
.
1. vertical compression type mould closing mechanism assembling is simple, and rigging error is less, thus has ensured higher repetitive positioning accuracy.Because servomotor moment of torsion control accuracy is high, ball-screw and Clamping System are rigidly connected; Make out the also corresponding raising of the speed of mould assembling action, positional precision; ensure that the accurate of template motion thrust; control template at the volley inertia produce offset deviation; make low pressure mould protect the reliability of This move and response accuracy greatly to improve, security when precision die uses has had better guarantee.When some thin-gage goods of injection moulding, need to carry out " note one is pressed " composite move, namely when injecting beginning, mould does not conform to tightly, leaves very little gap to be vented, and action of injection later stage mould closes tight.The goods flatness adopting " note one is pressed " composite move to make is high, without buckling deformation.Such action request template movement has higher positional precision and response speed.Because mould closes tight at the later stage, so only need less mold clamping force just plastic goods, this will extend injector and mold use life-span.
2. the high accuracy of the utility model mould assembling action makes that high velocity, low pressure operating distance lengthens, closure pressing speed is faster.Because whole machine is all driven by motor, substantially do not disturb between each action; So, open and touch and eject action and can synchronously carry out, save the time ejecting action, achieve " die sinking-eject " composite move that general fluid pressure type injector cannot realize.
