DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 6 The utility model provides a technical solution: a pneumatic clamp for a die-casting mold, comprising a base 1, a cylinder 2 fixedly connected to the top of the base 1, a gas rod 3 arranged at the output end of the cylinder 2, a first connecting plate 4 fixedly connected to the right end of the gas rod 3, a clamping plate 7 arranged on the right side of the first connecting plate 4, a die-casting mold 9 arranged on the inner side of the clamping plate 7, a pushing mechanism 5 arranged on the inner side of the first connecting plate 4, and an elastic mechanism 6 arranged on the rear side of the pushing mechanism 5;

[0023] The pushing mechanism 5 includes a second connecting plate 501 arranged at the front end of the left side of the first connecting plate 4, a threaded rod 502 is arranged inside the front end of the first connecting plate 4, the second connecting plate 501 is connected to the first connecting plate 4 in a lateral sliding connection, and the second connecting plate 501 is connected to the threaded rod 502 in a rotating connection, and the threaded rod 502 is connected to the first connecting plate 4 in a threaded connection, so that the rotating threaded rod 502 can move the first connecting plate 4 back and forth, the rear end of the second connecting plate 501 is fixedly connected to a limiting rod 503, and a first hole 504 is arranged inside the rear end of the first connecting plate 4, the limiting rod 503 and the first hole 504 are matched in a clearance fit, and the appearance structure of the limiting rod 503 The shape is a rectangular parallelepiped, the central axis of the limit rod 503 is perpendicular to the central axis of the first connecting plate 4, and the number of the limit rods 503 is consistent with the number of the limit rods 503, so that the limit rod 503 can move laterally on the inner side of the first hole 504, but will not rotate. A fixing rod 505 is arranged on the inner side of the first hole 504, and a second hole 506 is arranged inside the left end of the limit rod 503. The shapes of the two sides of the rear end of the limit rod 503 are inclined, and the matching mode of the limit rod 503 and the second hole 506 is clearance matching, and the shapes of the two sides of the front end of the second hole 506 are inclined, so that after the hypotenuse of the limit rod 503 contacts the hypotenuse of the second hole 506, the fixing rod 505 is pushed to move laterally.

[0024] A groove 8 is provided in the middle of the limiting rod 503, and the elastic mechanism 6 includes an elastic rubber pad 601 provided on the inner side of the groove 8. A baffle 602 is fixedly connected to the outer side of the elastic rubber pad 601. The upper ends of the baffle 602 have inclined surfaces on both sides, and the baffle 602 and the groove 8 are matched in a clearance fit. There are two symmetrical grooves 8 about the central axis of the limiting rod 503, so that after the baffle 602 contacts the hypotenuse of the first hole 504, it will move along the hypotenuse of the baffle 602 toward the inner side of the groove 8. When the fixing rod 505 is displaced due to vibration, the baffle 602 will provide a certain resistance to prevent the fixing rod 505 from displacing too much, making it inconvenient for the fixing rod 505 to move to the inner side of the first hole 504.

[0025] Lift the clamping plate 7 and drive the fixing rod 505 to move toward the inner side of the first hole 504, so that the baffle 602 moves along its own oblique side to the inner side of the groove 8. When moving out of the range of the first hole 504, the baffle 602 is reset. After waiting for all the clamping plates 7 to be installed, rotate the threaded rod 502 to drive the second connecting plate 501 to move toward the rear side, and drive the limiting rod 503 to move toward the rear side and move to the inner side of the second hole 506, thereby limiting the fixing rod 505 and the clamping plate 7, thereby achieving the purpose of facilitating the limiting of the clamping plate 7.
