Description

Technical Field

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

[0002] Die casting is a kind of pressure-casting part. It uses a pressure casting machine equipped with a casting mold to pour liquid metals such as copper, zinc, aluminum or aluminum alloy into the inlet of the die casting machine. The die casting machine is die-cast to cast copper, zinc, aluminum or aluminum alloy parts in the shape and size limited by the mold. Such parts are usually called die castings.

[0003] During the production process of metal die-casting, parts are extracted and inspected many times. Especially when die-casting is completed, personnel will take out the die-casting to check whether it is qualified. Although the die-casting parts are cooled, for the parts of sampling inspection, in order to improve the inspection efficiency, they are taken out when they are cooled to their final shape. At this time, the temperature is still higher than the body temperature, so personnel will use clamps to clamp the parts. In addition, there are burrs and burrs on the parts in front of the grinding station. It is easy to scratch people if they are picked up directly by hand, so clamps are often used to pick up parts.

[0004] However, the existing clamp structure adopts the simplest lever principle, which is similar to the structure of scissors. The two plates are connected by a connecting shaft, one side is the force-applying part, and the other side is the clamping part. Technical personnel in this field know from use that since the force arm of the force-applying part is short and the direction of action is continuously changing when the force is applied, it is more difficult for personnel to operate. In addition, this structure has basically no limit in the vertical direction of force application. If a large force is applied, the two plates may deviate to the side, and the clamping is unstable. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the utility model provides a metal die-casting clamp, in which a pair of clamping plates are respectively rotatably arranged between a pair of fixed plates through a connecting shaft to ensure the stability of the clamping plates during operation. The sliding openings of the force-applying parts of the clamping plates are crossed, and the sliding rod on the mounting plate is pulled by a moving rod to drive the sliding opening and the cross angle of the force-applying parts to change, so that the clamping parts of the clamping plates clamp the parts. Personnel only need to apply force to the handle in the vertical direction. The operation is convenient and labor-saving, and the clamping is stable.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The cam is an angular channel that is formed on a pair of camshafts and on two opposite ends of the camshaft are engaged to the handle and the handle is engaged to the handle, the cam being connected to the handle by a force applying portion and a clamping portion. The force applying portion and the clamping portion form an obtuse angle, and the pair of clamping portions are arranged between the pair of fixed plates, and the inflection point position corresponding to the force applying portion and the clamping portion is rotatably connected to the two ends of the bottom of the fixed plate through a connecting shaft. The force applying portion is provided with a sliding opening, and the two sliding openings of the pair of clamping plates intersect, and a sliding rod is arranged through the intersection. A limiting hole is arranged at the center position of the cross plate, and the moving rod vertically moves through the limiting hole. A mounting plate is arranged at the bottom of the moving rod, and the mounting plate is U-shaped, and both ends of the sliding rod are connected to the inner wall of the mounting plate. The handle is arranged at the upper end of the moving rod, and the handle is arranged on the upper surface of the cross plate and wraps the handle inside. A clamping rod is arranged at the lower end of the clamping portion of the clamping plate, and the clamping rod is perpendicular to the clamping plate.

[0008] Preferably, a clamping plate is provided at the upper end of the movable rod, a tension spring is provided between the clamping plate and the horizontal plate, the upper end of the tension spring is fixedly connected to the clamping plate, and the lower end is fixedly connected to the upper surface of the horizontal plate.

[0009] Preferably, the cross-sections of the limiting hole and the moving rod are uniformly rectangular.

The moving rod 2 moves vertically through the limiting hole 15, and a mounting plate 5 is arranged at the bottom of the moving rod 2. The mounting plate 5 is U-shaped, and both ends of the slide rod 8 are connected to the inner wall of the mounting plate 5. The handle 4 is arranged at the upper end of the moving rod 2, and the handle 3 is arranged on the upper surface of the horizontal plate 1, and the handle 4 is wrapped inside. A clamping rod 9 is arranged at the lower end of the clamping part 62 of the clamping plate 6, and the clamping rod 9 is perpendicular to the clamping plate 6; a clamping plate 13 is arranged at the upper end of the moving rod 2, and a tension spring 12 is arranged between the clamping plate 13 and the horizontal plate 1, and the upper end of the tension spring 12 is fixedly connected to the clamping plate 13, and the lower end is fixedly connected to the upper surface of the horizontal plate 1; the cross-section of the limiting hole 15 and the moving rod 2 is uniformly rectangular; a rubber sleeve 14 is sleeved on the clamping rod 9.

[0021] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0022] According to the instruction manual Figure 1-4 The lever 6 is then moved back and forth, and the two levers 6 are brought into contact with each other, and the two levers 6 are brought into contact with each other, so that the lever 6 is moved in a direction opposite to the lever 14. The clamping plate 6 is arranged between a pair of fixing plates 7 , which is equivalent to limiting the clamping plate 6 to prevent it from shaking in a direction perpendicular to the rotation plane of the clamping plate 6 , thereby ensuring its stability during operation and also ensuring the stability when clamping the part 16 .
