Embodiment Construction

[0013] Now in conjunction with accompanying drawing, the patent of the present invention is described in detail as follows:

[0014] like figure 1 As shown, the present invention is a hybrid-driven mold clamping mechanism for an all-electric injection molding machine, including a toggle mechanism 6 , a support plate 4 , a tie rod 5 , a threaded crosshead 11 , an adjusting nut 2 , a moving platen 7 and a fixed platen 9 . There may be multiple tie rods 5, which are center-symmetrically distributed, i.e. diagonally symmetrical, triangularly symmetrical or other centrally symmetrical shapes. The support plate 4 is screwed to the threaded tie rod part 13, and the fixed template 9 is fixedly mounted on the tie rod 5. The movable template 7 is installed on the pull rod 5 and can move along the pull rod 5 . A threaded crosshead 11 is installed in the middle of the support plate 4, and the two are threaded. The conventional motor 3 acts on one end of the threaded crosshead 11 through ...

Abstract

The invention relates to a combination driving-type compound die mechanism of a full electric injection molding machine, belonging to the field of compound die mechanism, comprising an external synchronous belt, an adjusting screw nut, a conventional motor, a support plate, a pull rod, a toggle rod mechanism, a movable platen, a mould, a fixed die plate, a support angle, a screw thread crosshead, a servo motor, a screw-threaded draw bar and an internal synchronous belt. The compound die mechanism adopts combination drive principle to design, and the power source is the servo motor and the conventional motor. Output motion of the servo motor, linear motion of the support plate and output motion generated by the conventional motor, linear motion of the supporting angle are synthesized through a toggle rod mechanism of two degrees of freedom to generate programmable output motion. The system combines the advantages of a traditional mechanical system and a total servo electromechanical system, can realize flexible output motion, has the characteristics of high loading capacity, rapid operational speed and low cost.

Description

technical field [0001] The invention relates to a mold clamping mechanism of an injection molding machine, in particular to a mold clamping mechanism of an all-electric injection molding machine. technical background [0002] At present, most mold clamping mechanisms in injection molding machines are still hydraulic or toggle. The hydraulic type has high requirements on the oil circuit and sealing system; the toggle type lacks flexibility, and its output characteristics are difficult to change. If a servo motor is used for driving, the controllability of the servo motor speed can be used, and the same mechanism can meet various output requirements by controlling the input of the motor without changing the rod length of the mechanism. The cost is high and the power is low, and its application is limited to small processing equipment. [0003] The idea of ​​hybrid drive mechanism proposed in recent years is a good way to solve this problem. That is to say, a two-degree-of-f...
