Description
Technical field
This utility model relates to injection machine manufacturing technology field, particularly to the clamping mechanism of a kind of injection moulding machine.
Background technology
Existing full electricity injection moulding machine clamping mechanism is usually by servomotor by certain amplification ratio belt pulley system; the moment of torsion exported by servomotor amplifies on the straight-line ball screw mandrel that deceleration is transported to be attached thereto; the crosshead of mould-locking structure is driven again by straight-line ball screw mandrel; thus reach to control whole injection moulding machine locked mode componental movement; and crosshead guide bar is installed on tailgate, relative deformation is bigger.Therefore, the locked mode part belt pulley system apparatus structure of this full electricity injection machine is more complicated and huge, affects the installation of machine, and ball screw tandem degree trueness error is relatively large.In addition, use this structure electric mould-locking structure injection moulding machine, need to readjust belt transmission rate of tension after using certain time, there is the problems such as belt service life is shorter.
Summary of the invention
The purpose of this utility model is to provide the electric mode locking mechanism of the injection moulding machine that a kind of structure is simpler, easy for installation, length in service life, control accuracy are higher.
This utility model the technical scheme is that the electric mode locking mechanism of a kind of injection moulding machine for achieving the above object, including servomotor, ball screw, bearing block, crosshead, screw rodb base, tailgate, also include reductor, reductor is arranged in the end face outside of tailgate, servomotor is arranged on reductor, servomotor front end is stretched into reductor rear end directly rigidly fixing with reductor and is connected, bearing block is arranged on the middle part of tailgate, screw rodb base is arranged on the middle part of crosshead, ball screw one end is positioned in bearing block, the ball screw other end is arranged in the screw rodb base in crosshead, the output shaft of reductor is connected with the ball screw being positioned at bearing block one end, the power of servomotor passes to ball screw through reductor, ball screw drives crosshead to realize opening mould assembling action again.
Further technical scheme of the present utility model is: be provided with four pull bars doing to guide for crosshead between described tailgate and moving platen, crosshead generally rectangular configuration, four pull bars are each passed through crosshead and are positioned in four pilot holes at corner, and ball screw is positioned at the middle part of four pull bars.
Further technical scheme of the present utility model is: described reductor is planetary reducer, and described servomotor is AC servo motor.
The electric mode locking mechanism of this utility model injection moulding machine has the advantages that AC servo motor is passed through the fixing rigid structure of planetary reducer and ball screw affixed formation high intensity by this utility model; compared with traditional belt pulley system; the drive disk assembly used is less, rotary power transmission distance is shorter; make electric mode locking system structure simpler compact, quick and easy for installation；And crosshead uses four pull bars of clamping mechanism to guide as it, ball screw is positioned at the middle part of four pull bars, makes ball screw installation accuracy be greatly improved, and reduces the wear extent of ball screw, improves machine and opens mould assembling action running precision and response speed；And this utility model electric mode locking mechanism is fixing rigid structure; locked mode responds faster, and structure is taken up space less, and machine is more attractive and structure is more coordinated; use this utility model electric mode locking mechanism also to reduce technological difficulties and manufacturing cost, and improve the service life of these locked mode parts.
With embodiment, the electric mode locking mechanism of this utility model injection moulding machine is further described below in conjunction with the accompanying drawings.

Drawing reference numeral illustrates: 1-AC servo motor, 2-planetary reducer, 3-bearing block, 4-ball screw, 5-pull bar, 6-crosshead, 7-screw rodb base, 8-tailgate, 9-moving platen.
Detailed description of the invention
As shown in Figure 1; the electric mode locking mechanism of this utility model injection moulding machine; including servomotor, ball screw 4, bearing block 3, crosshead 6, screw rodb base 7, tailgate 8, reductor; in the present embodiment; reductor is planetary reducer 2; certainly reductor can also be box reductor etc., and servomotor is AC servo motor 1.Planetary reducer 2 is arranged in the end face outside of tailgate 8, AC servo motor 1 is arranged on reductor, AC servo motor 1 front end is stretched into planetary reducer 2 rear end directly rigidly fixing with planetary reducer 2 and is connected, this mode simply uses a drive disk assembly i.e. planetary reducer 2, and its structure is simpler compared with existing pulley drive technology.AC servo motor 1 is affixed with planetary reducer 2 so that the transmission Distance Shortened of rotary power, improves AC servo motor 1 rapid response speed and driving force.
Bearing block 3 is fixedly mounted on the middle part of tailgate 8, screw rodb base 7 is fixedly mounted on the middle part of crosshead 6, ball screw 4 one end is positioned in bearing block 3, ball screw 4 other end is arranged in the screw rodb base 7 in crosshead 6, the output shaft of planetary reducer 2 is connected with the ball screw 4 being positioned at bearing block 3 one end, the power of AC servo motor 1 passes to ball screw 4 through planetary reducer 2, and ball screw 4 drives crosshead 6 to realize opening mould assembling action again.Ball screw 4 rotates driving by AC servo motor 1 with planetary reducer 2; export corresponding moment and rotary speed, drive crosshead 6, thus drive whole clamping mechanism to move; mould assembling action is opened in realization, and by the pressure flow output moment of torsion needed for Shooting Technique and rotating speed.In order to improve the stationarity of die open/close movement, tailgate 8 is horizontally disposed with bearing block 3, it guarantees micron order ball screw 4 motion precision positioning.
Being provided with four between tailgate 8 and moving platen 9 and do the pull bar 5 guided, crosshead 6 generally rectangular configuration for crosshead 6, four pull bars 5 are each passed through crosshead 6 and are positioned in four pilot holes at corner, and ball screw 4 is positioned at the middle part of four pull bars 5.Compare the tailgate crosshead guide bar that conventional injection molding machine uses; so can reduce guide rod deformation, it is ensured that the installation linearity of ball screw, be substantially reduced ball screw abrasion; and improve service life of this electric mode locking mechanism, the most also can further improve kinematic accuracy of the present utility model.
This utility model not only action response is fast, low cost, simple in construction, life-span length, easy to maintenance, and substantially increase the folding mould action control precision of injection machine.
Above-mentioned embodiment is the most for illustration of the utility model; and be not to restriction of the present utility model; those of ordinary skill about technical field; all made within spirit of the present utility model and principle any amendment, equivalent etc., within should be included in protection domain of the present utility model.
