Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a hydraulic clamp. Background Art

[0002] In die-casting production, die-casting machines need to frequently replace molds to meet the production needs of different products. However, there are some problems with traditional clamps during use, such as: installing pads at the clamping part of the mold is time-consuming and labor-intensive, and it is easy to cause accidents due to the thickness deviation of the pads; the clamp is inconvenient to move in the T-slot, and the outside does not have a protective function, so that the release agent, dust and other debris that affect the action are easy to invade the inside of the device, reducing its service life. In order to solve these problems, an extended clamp for die-casting quick mold change came into being. A T-shaped slider is arranged at the bottom of the main body of the clamp, a cylinder body is arranged in one end of the main body, a piston is arranged in the cylinder body, a pressure plate is arranged above the piston, a mounting hole is opened in the end of the pressure plate away from the piston, a connecting shaft is arranged in the mounting hole, and both ends of the connecting shaft are respectively arranged in the matching connecting holes, and the matching connecting holes are respectively opened in the left and right side walls of the main body, and a protective shell is arranged on the outer jacket of the main body.

[0003] The mold clamp is equipped with a protective shell to prevent release agents, dust and other debris from entering the device, thereby extending its service life. At the same time, the cylinder body cooperates with the piston, pressure plate and connecting shaft to work on the principle of leverage. The mold mounting plate can be kept consistent without the use of pads, which saves time and effort and is safer and more reliable. Summary of the invention

[0004] The utility model provides an extended die clamp for quick die change of magnesium alloy die casting, in order to avoid the interference area between the body and the die and enhance the working stability, the utility model provides the following technical solutions:

[0006] The extension length of the pressing plate pressing head is 64 mm.

[0007] The oil cylinder described above is an 8-ton hydraulic cylinder.

[0008] On the left and right sides of the fixture body described above, there are T-shaped grooves respectively, which are connected in cooperation with T-shaped base reinforcement parts.

[0009] After the wheel assembly is subjected to pressure, it squeezes the spring and moves upward along an inclined connecting shaft of the connector.

[0010] The wheel assembly is equipped with a motor, and the rotating shaft of the motor is directly connected to the center of the wheel.

[0013] Connect the T-shaped base reinforcement part to the T-shaped groove on the side of the fixture body, and then slide the T-shaped base fixedly installed at the bottom of the fixture body and the T-shaped base reinforcement part together in the T-shaped groove of the workbench. At this time, since the moving component connected to the rear end of the film gripper is lower than the workbench, the wheel assembly is subjected to pressure to squeeze and tighten the spring, and the spring presses the wheel against the workbench in the reverse direction. Then start the motor to drive the film gripper to move to the working location, start the oil cylinder to introduce oil from the oil inlet pipe, thereby raising the piston of the oil cylinder and lifting the tail end of the pressing plate, so that the front end of the pressing plate presses the mold tightly.

[0014] The utility model has the following beneficial effects:

[0015] The pressing plate is delayed to 64 mm, effectively avoiding the interference area between the body and the mold, being able to adapt to larger-sized or special-shaped molds, providing a wider range of applicability, being able to be compatible with more different specifications of die-casting equipment and molds, and reducing the frequency of replacing the mold gripper due to mold size differences. Adding the T-shaped base reinforcement part to the side of the fixture body can withstand greater external forces and loads, ensuring a more stable and reliable connection between the mold and the equipment during the working process, and reducing faults and safety hazards caused by loose connections. Adding the moving component reflects certain intelligent and automated characteristics, helping to improve the automation level of the entire production process. The fast and automatic moving method reduces the production interruption time caused by the movement of the mold gripper and maintains the continuity of production. BRIEF DESCRIPTION OF THE DRAWINGS
