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 mold adjusting nut 1, a toggle mechanism 5, a support plate 3, a pull rod 4, a threaded screw 13, a threaded crosshead 14, a movable template 6, a fixed Template 8 and mold 7. There can be multiple tie rods 4, which are symmetrically distributed in the center, that is, diagonally symmetrical, triangularly symmetrical or other centrally symmetrical shapes. The support plate 3 is installed on the tie rod 4, and the mold adjusting nut 1 adjusts the support plate 3 according to the thickness of the mold 8. At the position on the pull rod 4, the pull rod 4 is fixed on the fixed template 8, the movable template 6 is sleeved on the pull rod 4, and the toggle mechanism 5 drives the movable template 6 to reci...

Abstract

The invention relates to a combination drive type mould clamping mechanism of an all-electric injection molding machine, belonging to the field of mould clamping mechanisms of injection molding machines. The combination drive type mould clamping mechanism of the all-electric injection molding machine comprises mould adjusting nuts, a conventional motor, a support plate, a pull rod, a toggle mechanism, a dynamic mould plate, a mould, a fixed mould plate, a supporting angle, a hinge sleeve, a servo motor, an externally synchronous belt, a threaded screw rod, a threaded crosshead and an internally synchronous belt. The combination drive type mould clamping mechanism is designed by adopting a combination drive principle, and a power source of the combination drive type mould clamping mechanism is the servo motor and the conventional motor; the combination drive type mould clamping mechanism combines input motions generated by the servo motor and the conventional motor through a two-degree of freedom toggle mechanism and then generates programmable output motions; the system combines the advantages of the traditional mechanical system and a full-server electromechanical system, can realize the flexibility of the output motion and has high carrying capacity, fast operation 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, all electric injection molding machines use toggle-type clamping mechanisms driven by servo motors. Due to the lack of flexibility of the toggle-type mold clamping mechanism, its output characteristics are difficult to change; at the same time, the servo motor is limited by the output power, cannot provide a large clamping force, and the manufacturing cost is high. [0003] The present invention proposes a hybrid-driven mold clamping mechanism for an all-electric injection molding machine. A two-degree-of-freedom hybrid-driven mechanism is used as the driving mechanism of the mold clamping mechanism, and one of the driving parts is driven by a high-power conventional motor to move at a constant speed. A low-power servo motor controls anothe...
