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 1-2 In this embodiment, a CNC processing device for convenient mold replacement includes a support table 1, the upper end of the support table 1 is fixedly connected to a support plate 2, the upper end of the support plate 2 is fixedly connected to a top plate 3, and a hydraulic rod 5 with one end penetrating the top plate 3 is fixedly installed on the top plate 3;

[0023] A processing part 4 is arranged on the support platform 1;

[0024] The workpiece 4 includes a movable plate 41, one end of which is fixedly connected to the output end of the hydraulic rod 5. The lower end of the movable plate 41 and the upper end of the support platform 1 are fixedly connected with a mounting frame 42. A mounting block 43 is placed on the inner side of the mounting frame 42. The lower end of the top mounting block 43 is fixedly connected with a punch 45, and the upper end of the bottom mounting block 43 is fixedly connected with a die 47. A telescopic plate 44 is slidably connected between the movable plate 41 and the support platform 1. The outer side of the telescopic plate 44 is rotatably connected to a threaded rod 48 with one end passing through the support plate 2. The inner side of the telescopic plate 44 is fixedly connected to an insert block 46 with one end passing through and extending to the inside of the mounting block 43. The outer side of the movable plate 41 is fixedly connected to a guide frame 49 located on the outer side of the support plate 2.

[0025] In this embodiment, since rotating the threaded rod 48 can drive the telescopic plate 44 to move and adjust horizontally, it drives the plug block 46 on the telescopic plate 44 to extend into the top and bottom mounting blocks 43 respectively, so as to install and fix the punch 45 and the die 47. Conversely, the threaded rod 48 is rotated in the opposite direction to pull the plug block 46 and the mounting block 43 apart through the telescopic plate 44, so that the mounting block 43 can be disassembled to separately disassemble and replace the punch 45 and the die 47, thereby improving the convenience of disassembly and replacement.

[0026] Among them, the outer side of the mounting block 43 is fixedly connected to a limit block 410 with one end extending into the interior of the mounting frame 42, and the inner wall of the mounting frame 42 is provided with a limit groove located on the outer side of the limit block 410, and the mounting block 43 is limited and guided by the limit block 410 extending into the limit groove.

[0027] In addition, a slot 411 located outside the plug block 46 is formed on the outer side of the mounting block 43, and the mounting block 43 is supported and fixed by the plug block 46 extending into the slot 411. A through hole is formed on the inner wall of the mounting frame 42 and located outside the plug block 46, and the plug block 46 is guided by the through hole on the mounting frame 42.

[0028] Secondly, the through hole, the slot 411 and the plug block 46 are all cross-shaped, and the length of the top plug block 46 is greater than that of the bottom plug block 46, so that during the separation process of the plug block 46 and the mounting block 43, the bottom plug block 46 will be separated from the mounting block 43 in advance, so as to facilitate the operator to remove and replace the die 47 and the punch 45 in sequence.

[0029] Then, a threaded hole is opened inside the support plate 2 and is located outside the threaded rod 48 . The threaded hole cooperates with the threads outside the threaded rod 48 , so that the rotating threaded rod 48 can be moved and adjusted laterally on the support plate 2 .

[0030] See also Figure 1 Or 3, in this embodiment, the telescopic plate 44 is composed of a sleeve plate and a slide plate, the slide plate is slidably connected to the inner side of the sleeve plate, the threaded rod 48 is rotatably connected to the sleeve plate, the lower end of the sleeve plate and the upper end of the slide plate are fixedly connected with a slider 412, the lower end of the movable plate 41 and the upper end of the support platform 1 are provided with a slide groove, and the slider 412 is slidably connected to the inner side of the slide groove.

[0031] In this embodiment, there are two telescopic plates 44, which are symmetrically distributed between the support platform 1 and the movable plate 41. There are four plug-in blocks 46, which are symmetrically distributed on the slide plate and the sleeve plate in groups of two.

[0032] The working principle of the above embodiment is:

[0033] Since rotating the threaded rod 48 can drive the telescopic plate 44 to move and adjust horizontally, the plug block 46 on the telescopic plate 44 can be driven to extend into the top and bottom mounting blocks 43 respectively, so as to install and fix the male mold 45 and the female mold 47. Conversely, rotating the threaded rod 48 in the opposite direction can pull the plug block 46 and the mounting block 43 apart through the telescopic plate 44, so that the mounting block 43 can be disassembled to separately disassemble and replace the male mold 45 and the female mold 47, thereby improving the convenience of disassembly and replacement.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
