Detailed Description
Example 1
The five-plate toggle rod type die clamping device disclosed by the invention is shown in fig. 1, and mainly comprises a left fixed die plate 1, a left movable die plate 2, a right movable die plate 6, a right fixed die plate 7, a left toggle rod 3, a connecting rod 4, a right toggle rod 5, a die locking oil cylinder 9, a central plate 10, a pull rod 11, a push rod 12 and a push plate 13. The center plate 10 is fastened and connected with the base 14 by bolts, and the left fixed die plate 1 and the right fixed die plate 7 are respectively arranged at the left and right positions of the center plate 10 and are respectively fastened and connected with the center plate 10 by pull rods 11. The left movable mould plate 2 and the right movable mould plate 6 are provided with four holes, and can slide along the four pull rods under the action of the driving part. The three-dimensional structure of the driving part is shown in fig. 2, and the mold locking cylinder 9 is fixed on the center plate 10, and is arranged in front of and behind. The center plate 10 and the push plate 13 are connected through two sliding pairs, and the piston rod of the oil cylinder directly drives the push plate 13 to move left and right along the slideway. The two connecting rods 4 are arranged up and down and are connected with the central plate 10 through a connecting pin shaft, each connecting rod is connected with a left toggle rod 3 and a right toggle rod 5 through two pin shafts, the toggle rods are also connected with the movable templates through pin shafts, so that the actions of the two templates are connected in series, the right die opening during left die assembly is realized, and the left die opening is realized during right die assembly. The left toggle rod is provided with a pin shaft hole, and is connected with a push plate 13 through an upper push rod 12 and a lower push rod 12.
When the left side mold closing action is performed, the mold locking oil cylinder 9 acts to push the push plate 13 to move leftwards, and the left toggle rod 3 pushes the left movable mold plate 2 to move leftwards due to the connection of the push rod 12, so that the left side mold closing action is realized; the connecting rod 4 rotates around the rotating shaft of the central plate 10 to drive the right toggle rod 5 and the right movable die plate 6 to move leftwards, so that the die opening of the right die 8 is realized. When the mold contacts, the connecting rod 4 and the left toggle rod 3 are in an unbending state, and under the thrust action of the mold locking oil cylinder 9, the mechanism generates force amplification action to deform the mold clamping device until the connecting rod 4 and the left toggle rod 3 are straightened and enter self-locking.
