Technical Field

[0001] The utility model relates to the technical field of taking out a concave die of an automobile stamping die, in particular to a device for taking out a concave die of an automobile stamping die. Background Art

[0002] Automobile mold, in a narrow sense, is the general term for molds for all stamping parts on the automobile body. That is, "automobile body stamping mold", for example, top cover flanging mold, beam reinforcement plate pressing mold, etc.

[0003] In the existing process of removing the die of an automobile stamping die, the inside of the die is usually clamped and fixed by a fixing block. Since the die is installed at a deep position, a single fixing clamp is not convenient for removing the die all at once, and the die usually needs to be clamped and fixed repeatedly. Therefore, it is particularly important to provide a removal device that can enhance the gripping force of the die. In view of this, we propose a removal device for the die of an automobile stamping die. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art, meet the actual needs, and provide a device for removing the die of an automobile stamping die, so as to solve the technical problem that the currently used single clamping assembly is not convenient for removing the die at one time.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is as follows: designing a device for removing the die of an automobile stamping die, comprising a rod body, the upper end surface of the rod body is arranged with a cover plate, the interior of the rod body is divided into an upper cavity and a lower cavity by a side wall, a threaded rod A is rotatably connected to the inner wall of the upper cavity, the top end of the threaded rod A passes through the side wall of the cover plate and is fixedly connected with a handle wheel, and a tensioning assembly is arranged on the surface of the threaded rod A;

[0006] The tensioning assembly includes a connecting block threadedly connected to the surface of the threaded rod A, at least one group of connecting plates are fixed to the surface of the connecting block, a connecting rod is rotatably connected between two of the connecting plates, a plurality of through grooves are opened on the surface of the rod body, the surface of the connecting rod is slidably connected in the through grooves, and the end of the connecting rod is rotatably connected to a clamping block via a rotating shaft, and the shape of the clamping block is set to be semi-arc.

[0007] Preferably, an air suction component is provided in the lower cavity;

[0008] The air suction component includes an annular through hole opened at the bottom end of the lower cavity, the bottom end of the lower cavity is rotatably connected with a threaded rod B, the surface of the threaded rod B is threadedly connected with an air suction plate, and the interior of the threaded rod B is opened as a through cavity.

[0009] Preferably, the top end of the threaded rod B is fixedly connected with a bevel gear A, and the surface of the bevel gear A is meshingly connected with a bevel gear B.

[0010] Preferably, a rotating rod is fixedly connected to one side of the bevel gear B, and a turning handle is fixedly connected to the surface of the rotating rod through the side wall of the rod body.

[0011] Preferably, a suction cup is fixedly connected to the bottom end of the rod body, and the interior of the suction cup is communicated with the lower cavity.

[0012] Preferably, the air intake plate is made of silicone material and its surface is in contact with the inner wall of the lower cavity. A limiting groove is provided on the side wall of the lower cavity, and the surface of the air intake plate is slidably connected in the limiting groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting the clamping block, the threaded rod A can be rotated to drive the clamping block to clamp and fix according to the dies of different sizes, so that the device can adapt to dies of more sizes, improving practicality. At the same time, by setting the semi-arc clamping block, the surface of the clamping block can be more closely fitted to the side wall of the circular die, which can increase the friction of the contact area and improve the gripping force of the clamping block.

[0015] 2. By setting the suction cup, the device can facilitate the close contact between the bottom of the rod body and the surface of the die. At the same time, through the suction component, when the suction cup is adsorbed on the surface of the die, negative pressure can be formed in the lower cavity, thereby increasing the adsorption capacity of the suction cup, making the device more closely connected with the die when taking out the die, thereby improving the efficiency of taking out the die.
