Abstract
The utility model discloses a mold closing device of a die-casting machine, comprising a rack. A tail board is arranged at the left end of the rack; an opening-closing hydraulic cylinder is arranged fixedly in the middle of the left end of the tail board; a sizing seat board is arranged at the right end of the rack; a pull rod is connected with the left end of the sizing seat board; the other end of the pull rod is connected with a mobile seat board; an elbow component is fixed at the left end of the mobile seat board; the other end of the elbow component is fixed at the tail board. In the moving process of mold closing, the movement speed of the mobile seat board is increased to the maximum from zero rapidly, and is then decreased gradually, the closing speed is zero when an elbow rod unbends gradually till completing, and the mechanism enters in a self-locking state; in the opening up process, the movement of the mobile seat board is changed to be fast-speed from low-speed, and then from fast-speed to low-speed till zero, thereby conforming to the whole movement requirements of the machine well, the device can operate safely, the ejection of a casting is smooth, and the cycle-index of the machine can also be increased.
Description
Technical field
The utility model relates to a kind of mold closing mechanism of die casting machine.
Background technology
The mold closing mechanism of traditional die casting machine adopts fluid pressure type mould assembly device, the mold closing mechanism of this mode can be realized and closing, the effect of die sinking action and locking die, ejecting product, but high pressure oil consumption is higher in the course of the work for this mold closing mechanism, the power of pump is larger, simultaneously because the work of hydraulic mould-matching device is more unstable, cause foundry goods to be not easy to eject, greatly reduce production efficiency.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of security of operation, and casting stable ejects, the mold closing mechanism of the die casting machine that energy consumption is less.
For achieving the above object, the technical solution of the utility model is: a kind of mold closing mechanism of die casting machine, comprise frame, the left end of described frame is provided with tailgate, in the middle of the left end of tailgate, is fixed with and runs type hydraulic cylinder jointly, and the right-hand member of described frame is provided with sizing seat board, the left end of sizing seat board is connected with pull bar, the other end of this pull bar is connected with ejector half seat board, and the left end of described ejector half seat board is fixed with toggle assembly, and the other end of toggle assembly is fixed on tailgate.
Further setting as such scheme: the tune type that the is provided with hydraulic motor of described tailgate.
Further setting as such scheme: described toggle assembly comprises hook hinge a, hook hinge b and hook hinge c, described hook hinge a is fixed on tailgate, between hook hinge a and hook hinge b, be hinged with the first band andgudgeon, described hook hinge c is fixed on ejector half seat board, between hook hinge b and hook hinge c, be hinged with the second band andgudgeon and connect, below and the frame of the first described band andgudgeon are hinged.
The beneficial effects of the utility model are: in matched moulds motion process, ejector half seat board translational speed is raised to maximum fast by zero, then slows down gradually, and while stretching gradually to termination along with toggle bar, mould assembly speed is zero, and mechanism enters self-locking state; In open form process, ejector half seat board moves by going at a slow speed fast, then meets very much the whole motion requirement of machine, and make type tool security of operation to zero by turning fast slow, and casting stable ejects, and can improve again the cycle-index of machine; This mold closing mechanism can amplify 16～26 times by the thrust of closing liquid cylinder pressure by toggle assembly, compares with fluid pressure type mould assembly device, and hydraulic oil depletion is few, the power of pump is corresponding reduces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of toggle assembly of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.
As shown in Figure 1 and Figure 2, the mold closing mechanism of a kind of die casting machine of the utility model, comprise frame 1, the left end of described frame 1 is provided with tailgate 2, in the middle of the left end of tailgate 2, is fixed with and runs type hydraulic cylinder 3 jointly, and the right-hand member of described frame 1 is provided with sizing seat board 4, the left end of sizing seat board 4 is connected with pull bar 5, the other end of this pull bar 5 is connected with ejector half seat board 6, and the left end of described ejector half seat board 6 is fixed with toggle assembly 7, and the other end of toggle assembly 7 is fixed on tailgate 2.
The tune type that the is provided with hydraulic motor 8 of described tailgate 2.
Described toggle assembly 7 comprises hook hinge a71, hook hinge b72 and hook hinge c73, described hook hinge a71 is fixed on tailgate 2, between hook hinge a71 and hook hinge b72, be hinged with the first band andgudgeon 74, described hook hinge c73 is fixed on ejector half seat board 6, between hook hinge b72 and hook hinge c73, be hinged with the second band andgudgeon and connect 75, below and the frame 1 of the first described band andgudgeon 74 are hinged.
In matched moulds motion process, ejector half seat board 6 translational speeds are raised to maximum fast by zero, then slow down gradually, and while stretching gradually to termination along with toggle bar, mould assembly speed is zero, and mechanism enters self-locking state; In open form process, ejector half seat board 6 moves by going at a slow speed fast, then meets very much the whole motion requirement of machine, and make type tool security of operation to zero by turning fast slow, and casting stable ejects, and can improve again the cycle-index of machine; This mold closing mechanism can amplify 16～26 times by the thrust of closing liquid cylinder pressure by toggle assembly 7, compares with fluid pressure type mould assembly device, and hydraulic oil depletion is few, the power of pump is corresponding reduces.
