In order to achieve the above object; The present invention is achieved in that combination drive type mould clamping mechanism of all-electric injection molding machine; Comprise mode transfer nut, conventional motor, gripper shoe, pull bar, elbow-bar mechanism, moving platen, mould, fixed form, an angle, hinge cover, servomotor, outer band, threaded screw rod, screw thread crosshead, inter-sync band synchronously, pull bar can be a plurality of, and distribution is centrosymmetric; Be diagonal angle symmetry shape, triangle symmetry shape or other center symmetry shapes; Gripper shoe is installed on the pull bar, and the mode transfer nut is according to the position of thickness adjusted gripper shoe on pull bar of mould, and pull bar is fixed on the fixed form; Moving platen is sheathed on the pull bar, and elbow-bar mechanism drives moving platen and moves back and forth.Servomotor, conventional motor are worked simultaneously.Be symmetrically installed with threaded screw rod on the gripper shoe, gripper shoe adopts with threaded screw rod and is threaded, and servomotor is connected with threaded screw rod one end through outer band synchronously, and the threaded screw rod other end is fixedly connected with the hinge cover, and hinge puts a fulcrum that connects elbow-bar mechanism.In the middle of the gripper shoe screw thread crosshead is installed, the two is for being threaded, and conventional motor is connected with the first end of screw thread cross through the inter-sync band, and the other end of this screw thread crosshead connects a fulcrum of elbow-bar mechanism.The rotation of servomotor converts the rectilinear motion of hinge cover to through threaded screw rod.The rotation of conventional motor converts the rectilinear motion at an angle to through the screw thread crosshead.Two kinds of rectilinear motions drive opening or closing of moving platen motion realization mould through a binary elbow-bar mechanism.
In the clamping of the present invention, being threaded between threaded screw rod and the gripper shoe can or be trapezoidal thread for the ball screw thread.
In the clamping of the present invention, being threaded between screw thread crosshead and the gripper shoe can or be trapezoidal thread for the ball screw thread.
In the clamping of the present invention, threaded screw rod is welding or riveted joint with the hinge inner room.
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 invention is following: (1) this clamping adopts combination drive principle, and wherein servomotor control provides flexible output movement, and shifting formwork, locked mode process kinematic accuracy is high, speed is fast, clamp force is accurate; (2) high-power conventional motor can provide bigger clamp force in the locked mode process, can be applicable to large-scale full electric injection molding machine; (3) common electric machine provides major impetus, and servomotor plays regulating action, and the two combination can replace high-power servomotor can greatly save cost.
Description of drawings
Fig. 1 is a combination drive type mould clamping mechanism of all-electric injection molding machine fundamental diagram of the present invention.
Among the figure: 1-mode transfer nut, the conventional motor of 2-, the 3-gripper shoe, the 4-pull bar, the 5-elbow-bar mechanism, the 6-moving platen, the 7-mould, the 8-fixed form, 9-props up the angle, and 10-cuts with scissors cover, 11-servomotor, the outer band synchronously of 12-, 13-threaded screw rod, 14-screw thread crosshead, 15-inter-sync band
The specific embodiment
Combine accompanying drawing that patent of the present invention is described in detail as follows at present:
As shown in Figure 1, the present invention is a combination drive type mould clamping mechanism of all-electric injection molding machine, comprises mode transfer nut 1, elbow-bar mechanism 5, gripper shoe 3, pull bar 4, threaded screw rod 13, screw thread crosshead 14, moving platen 6, fixed form 8 and mould 7.Pull bar 4 can be a plurality of; The distribution that is centrosymmetric is diagonal angle symmetry shape, triangle symmetry shape or other center symmetry shapes, and gripper shoe 3 is installed on the pull bar 4; Mode transfer nut 1 is according to the position of thickness adjusted gripper shoe 3 on pull bar 4 of mould 8; Pull bar 4 is fixed on the fixed form 8, and moving platen 6 is sheathed on the pull bar 4, and elbow-bar mechanism 5 drives moving platen 6 and moves back and forth.Servomotor 11, conventional motor 2 are worked simultaneously.Be symmetrically installed with threaded screw rod 13 on the gripper shoe 3; Gripper shoe 3 adopts with threaded screw rod 13 and is threaded; Servomotor 11 is through be with 12 to be connected with threaded screw rod 13 1 ends outward synchronously, and threaded screw rod 13 other ends are fixedly connected with hinge cover 10, a fulcrum of connection elbow-bar mechanism 5 on the hinge cover 10.In the middle of the gripper shoe 3 screw thread crosshead 14 is installed, the two is for being threaded, and conventional motor 2 is connected with screw thread crosshead 14 1 ends through inter-sync band 15, and the other end of this screw thread crosshead 14 connects a fulcrum of elbow-bar mechanism 5.The rotation of servomotor 11 converts the rectilinear motion of hinge cover 10 to through threaded screw rod 13.The rotation of conventional motor 11 converts the rectilinear motion at an angle 9 to through screw thread crosshead 14.
