[0022] like Figures 1 to 5As shown, a metal extrusion press with a die base positioning assembly 5 includes a front beam 1 and a die base assembly 2 slidably connected to the front beam 1. The die base positioning assembly 5 includes a positioning structure 7 provided on the die base assembly 2 and a positioning device 8 provided on the front beam 1. The positioning structure 7 is provided with a positioning groove 71. The positioning device 8 includes a positioning drive device 81 and a positioning element 82 that are connected by transmission. The positioning element 82 matches the shape of the positioning groove 71. When the die base assembly 2 moves to the position where the positioning element 82 corresponds to the position of the positioning groove 71, the positioning drive device 81 drives the positioning element 82 to be locked in the positioning groove 71.

[0023] In this embodiment, after the die base assembly 2 is moved into place, the positioning groove 71 corresponds to the positioning component 82. The positioning drive device 81 drives the positioning component 82 to be locked in the positioning groove 71 to restrict the movement of the die base assembly 2, thereby stabilizing the position of the die base assembly 2 and ensuring that the die base assembly 2 will not move or the movement range is within an acceptable range during operation, thus ensuring production quality.

[0024] In some specific embodiments, reference is made to Figure 1 and Figure 2 The opening of the positioning groove 71 faces upward. The positioning groove 71 has two inner sidewalls, which are arranged along the sliding direction of the mold base assembly 2. Each of the two inner sidewalls is provided with a first guide slope 711. The positioning member 82 is provided with two second guide slopes 821. During positioning, the two second guide slopes 821 correspond one-to-one with the two first guide slopes 711. The positioning drive device 81 is located on the front beam 1. The output end of the positioning drive device 81 faces downward. The positioning member 82 is located on the output end of the positioning drive device.

[0025] Considering the positional error and the dimensional error of the workpiece itself, the first guide slope 711 and the second guide slope 821 are set to guide the positioning part 82 to be smoothly locked in the positioning groove 71, which helps to improve the fault tolerance rate and improve the positioning efficiency of the mold base assembly 2.

[0026] In some specific embodiments, the positioning drive device 81 includes a positioning cylinder or a positioning hydraulic cylinder.

[0027] In some specific embodiments, reference is made to Figure 1 , Figure 3 and Figure 4 The front beam 1 is provided with an upper guide plate 3 and a lower guide plate 4, and a slide groove 11 is formed between the upper guide plate 3 and the lower guide plate 4. The mold base assembly 2 is locked on the slide groove 11 and can move along the slide groove 11.

[0028] The upper guide plate 3 and the lower guide plate 4 form a groove 11 for the mold base assembly 2 to slide. The lower guide plate 4 also serves to support the mold base assembly 2.

[0029] In some other embodiments, a slide rail is provided on the front beam 1, and the mold base assembly 2 is engaged on the slide rail to achieve a sliding connection on the front beam 1.

[0030] In some specific embodiments, reference is made to Figure 1 The mold base assembly 2 includes a mold base 21 and a mold base connecting seat 22. The upper and lower sides of the mold base connecting seat 22 are respectively provided with an upper guide boss 221 and a lower guide boss 222. The lower side of the upper guide plate 3 is provided with an upper guide groove 31, and the upper side of the lower guide plate 4 is provided with a lower guide groove 41. The upper guide boss 221 and the lower guide boss 222 are respectively engaged in the upper guide groove 31 and the lower guide groove 41.

[0031] Furthermore, the mold base 2 achieves a sliding connection with the front beam 1 through the upper guide boss 221, the lower guide boss 222, the upper guide groove 31, and the lower guide groove 41. This arrangement results in a larger contact area between the mold base assembly 2 and the upper guide plate 3 and the lower guide plate 4, making the installation of the mold base assembly 2 on the front beam 1 more stable and less prone to failure.

[0032] In some specific embodiments, reference is made to Figure 5 The front beam 1 is provided with a mounting plate 10, and the mounting plate 10 is provided with a mold base drive device 9 for driving the mold base assembly 2 to move. The mounting plate 10 is located at one end of the mold base assembly 2, and the mounting plate 10 is provided with a limiting bolt 101. The limiting bolt 101 protrudes from the side of the mounting plate 10 near the mold base assembly 2 and corresponds to the position of the mold base assembly 2.

[0033] When the mold base assembly 2 moves toward the mounting plate 10 and abuts against the limit bolt 101, the positioning groove 71 is located directly below the positioning member 82. At this time, the positioning cylinder drives the positioning member 82 to move downward and lock into the positioning groove 71. The limit bolt 101 can pre-position the mold assembly 2, which is beneficial for quick positioning of the mold assembly 2.

[0034] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
