Description

Technical Field

[0001] This utility model relates to the field of mold positioning technology, specifically a high-precision forging positioning structure for metallurgical molds. Background Technology

[0002] In the metallurgical mold processing industry, forgings are the core components of molds, and their machining accuracy directly determines the forming quality and service life of the mold. Whether it is the punch and die forgings of stamping dies or the cavity forgings of forging dies, in machining processes such as milling, grinding, and EDM, the forgings must be fixed on the worktable of the processing equipment by a positioning structure to ensure that the forging reference is aligned with the processing reference of the equipment, so as to avoid the scrapping of forgings or the mold forming dimensions exceeding tolerance due to positioning deviation.

[0003] When fixing forgings, there are generally two types of structures: rigid clamping and positioning structures and flexible adsorption and positioning structures. When using flexible adsorption and fixing, an adsorption groove is opened on the processing platform. However, in actual use, dust will enter the interior of the adsorption groove, affecting the adsorption and fixing effect.

[0011] As an optional solution of this utility model, a telescopic rod is fixedly connected to the surface of the sealing plate, and a limiting groove is formed on the inner wall of the adsorption tank relative to the position of the telescopic rod.

[0012] As an optional solution of this utility model, the limiting groove and the hollow cavity are interconnected, and the bottom of the telescopic rod is fixedly connected to the top of the base plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figure 1-3 A high-precision forging positioning structure for metallurgical molds includes a positioning platform 1, a controller 2 fixedly mounted on the side of the positioning platform 1, multiple positioning holes 3 on the top of the positioning platform 1, positioning pins 4 inserted into the inside of the positioning holes 3, and an adsorption mechanism 5 at the bottom of the positioning platform 1. When fixing the forging, the forging is first placed inside the multiple positioning holes 3 on the positioning platform 1, and then the positioning pins 4 are inserted into the positioning holes 3 for initial fixing. The adsorption mechanism 5 can then be used to complete the adsorption and fixing of the forging, thereby preventing the forging from shifting during processing.

[0026] The adsorption mechanism 5 includes an adsorption tank 51 located on the top of the positioning platform 1, and a pressure sensor 52 located inside the adsorption tank 51. An adsorption tube 53 is inserted through and fixedly sleeved into the bottom of the inner cavity of the adsorption tank 51. One end of the adsorption tube 53 is fixedly connected to an air pump 54. A hollow cavity 6 is formed in the inner wall of the adsorption tank 51. A dustproof mechanism 7 is set inside the hollow cavity 6. The pressure sensor 52 is fixedly installed at the bottom of the inner cavity of the dustproof mechanism 7. A solenoid valve 55 is fixedly installed on the adsorption tube 53. The air pump 54 is fixedly installed at the bottom of the positioning platform 1.

[0027] Specifically, when the forging is adsorbed and fixed, the air pump 54 and the solenoid valve 55 are turned on to evacuate the air from the adsorption tank 51. Under the action of the air pressure sensor 52, the air pressure can be detected. The adsorption tank 51 forms a sealed cavity through the forging. When the air pressure in the adsorption tank 51 reaches the set threshold, the air pump 54 and the solenoid valve 55 are turned off to complete the adsorption and fixing of the forging. By setting the hollow cavity 6 and the dustproof mechanism 7, the dustproof mechanism 7 can seal the adsorption tank 51 in the initial state to prevent dust from entering the adsorption tank 51. During adsorption and fixing, the adsorption force can expose the adsorption tank 51, which can avoid interference with the adsorption mechanism 5.

[0028] Furthermore, the dustproof mechanism 7 includes a base plate 71 disposed in the inner cavity of the hollow cavity 6, and a sealing plate 72 slidably connected to the inner wall of the adsorption tank 51. A spring 73 is fixedly connected to the opposite surfaces of the base plate 71 and the sealing plate 72. A through hole 74 is provided on the top of the base plate 71, and the diameter of the through hole 74 is smaller than the diameter of the sealing plate 72. In the initial state, under the elastic force of the spring 73, the sealing plate 72 can seal the adsorption tank 51. When the forging is fixed, under the action of the adsorption force, the adsorption force passes through the through hole 74 to adsorb the sealing plate 72, causing it to move downward and expose the adsorption tank 51, thereby adsorbing the forging placed on the positioning platform 1.

[0029] The sealing plate 72 is fixedly connected to a telescopic rod 75. A limiting groove 76 is formed on the inner wall of the adsorption groove 51 relative to the position of the telescopic rod 75. The limiting groove 76 and the hollow cavity 6 are interconnected. The bottom of the telescopic rod 75 is fixedly connected to the top of the base plate 71. By setting the telescopic rod 75, it can play a guiding role when the sealing plate 72 moves up and down. By setting the limiting groove 76, the movement of the telescopic rod 75 can be improved. At the same time, the sealing plate 72 can be limited so that its upper surface fits against the upper surface of the positioning platform 1.

[0030] It should also be noted that a support rod 77 is fixedly connected to the bottom of the base plate 71. The bottom end of the support rod 77 is fixedly connected to the bottom of the inner cavity of the hollow cavity 6. By setting the support rod 77, the base plate 71 can be supported and fixed.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
