The utility model promptly is to adopt combination drive principle that the full electric type clamping is improved; use servomotor and conventional motor to carry out combination drive, thereby realize the hybrid-driven clamping of high clamp force, high accuracy, low energy consumption, a kind of full electric injection molding machine simple in structure.
In order to achieve the above object; the utility model is achieved in that a kind of hybrid-driven clamping of full electric injection molding machine, comprises outer band synchronously, adjusting nut, conventional motor, gripper shoe, pull bar, elbow-bar mechanism, moving platen, mould, fixed form, an angle, screw thread crosshead, servomotor, threaded pull bar part and inter-sync band.Pull bar can be a plurality of, and the distribution that is centrosymmetric is diagonal angle symmetry shape, triangle symmetry shape or other center symmetry shapes, gripper shoe partly adopts with threaded pull bar and is threaded, fixed form is fixedly installed on the pull bar, and moving platen is installed on the pull bar, and can move along pull bar.The screw thread crosshead is installed in the middle of the gripper shoe, and the two is for being threaded, and conventional motor acts on the first end of screw thread cross by outer band synchronously, and this screw thread crosshead other end connects a fulcrum of elbow-bar mechanism.Gripper shoe is connected with the fulcrum of elbow-bar mechanism, and a fulcrum of elbow-bar mechanism links to each other with moving platen.Servomotor acts on the adjusting nut by the inter-sync band.The rotation of conventional motor converts the rectilinear motion at an angle to by the screw thread crosshead.The rotation of servomotor converts the rectilinear motion of gripper shoe with respect to threaded pull bar part to by adjusting nut, the opening or closing of the moving belt moving mold of moving platen.These two kinds of rectilinear motions drive the moving platen motion by a binary elbow-bar mechanism.
In the clamping of the present utility model, the type that is threaded between threaded pull bar part and the gripper shoe can be threaded or is the trapezoidal thread connection for ball.
In the clamping of the present utility model, being threaded between screw thread crosshead and the gripper shoe can or be trapezoidal thread for the ball screw thread.
Connecting rod in the elbow-bar mechanism can also can be spill connecting rod or convex connecting rod for the linear pattern connecting rod.
Major advantage of the present utility model is as follows:
(1) this clamping adopts combination drive principle, and wherein servomotor control provides flexible output movement, and shifting formwork, locked mode process kinematic accuracy height, speed is fast, clamp force is accurate; (2) in whole shifting formwork, locked mode process, servomotor is being controlled the rectilinear motion of gripper shoe, can constantly realize the automatic mold-adjustment effect, has improved control accuracy.(3) this utility model high-power conventional motor in the locked mode process can provide bigger clamp force, can be applicable to large-scale full electric injection molding machine; (4) high-power common electric machine provides major impetus in this utility model, and servomotor plays regulating action, can replace high-power servomotor can greatly save cost.

Fig. 1 is the hybrid-driven clamping fundamental diagram of a kind of full electric injection molding machine of the utility model.
Among the figure: the outer band synchronously of 1-, the 2-adjusting nut, the conventional motor of 3-, the 4-gripper shoe, the 5-pull bar, the 6-elbow-bar mechanism, the 7-moving platen, the 8-mould, the 9-fixed form, 10-props up the angle, 11-screw thread crosshead, 12-servomotor, the threaded pull bar part of 13-, 14-inter-sync band
The specific embodiment
Now in conjunction with the accompanying drawings the utility model patent is described in detail as follows:
As shown in Figure 1, the utility model is a kind of hybrid-driven clamping of full electric injection molding machine, comprises elbow-bar mechanism 6, gripper shoe 4, pull bar 5, screw thread crosshead 11, adjusting nut 2, moving platen 7 and fixed form 9.Pull bar 5 can be a plurality of, and the distribution that is centrosymmetric is diagonal angle symmetry shape, triangle symmetry shape or other center symmetry shapes, gripper shoe 4 is threaded with threaded pull bar part 13, fixed form 9 is fixedly installed on the pull bar 5, and moving platen 7 is installed on the pull bar 5, and can move along pull bar 5.Screw thread crosshead 11 is installed in the middle of the gripper shoe 4, and the two is for being threaded, and conventional motor 3 is by being with 1 to act on screw thread crosshead 11 1 ends outward synchronously, and these screw thread crosshead 11 other ends connect a fulcrum of elbow-bar mechanism 6.Gripper shoe 4 is connected with the fulcrum of elbow-bar mechanism 6, and a fulcrum of elbow-bar mechanism 6 links to each other with moving platen 7.Servomotor 12 acts on the adjusting nut 2 by inter-sync band 14.The rotation of conventional motor 3 converts the rectilinear motion at an angle 10 to by screw thread crosshead 11.The rotation of servomotor 12 converts the rectilinear motion of gripper shoe 4 with respect to threaded pull bar part 13 to by adjusting nut 2, the opening or closing of the moving belt moving mold 8 of moving platen 7.
Improvements of the present utility model just are to adopt combination drive principle, convert two power sources to two kinds of rectilinear motions: screw thread crosshead 11 is with respect to the rectilinear motion of gripper shoe 4, and gripper shoe 4 is with respect to the rectilinear motion of threaded pull bar part 13.These two kinds of rectilinear motions drive moving platen 7 motions by a binary elbow-bar mechanism 6.Because servomotor 12 is controllable motors, the high accuracy that moment of torsion that can be by regulating output and rotating speed are realized needed displacement, move fast, clamp force accurately and can finish shifting formwork, the locked mode motion of mode transfer automatically, be applicable to the variation of mould 8, in the locked mode process, provide bigger clamp force simultaneously by conventional motor 3.
