The die base assembly is slidably connected to a front beam and is also equipped with a power unit that is drively connected to it. When needed, the power unit moves the die base assembly to the required position, thereby enabling the metal extrusion press to complete the metal extrusion forming process.

[0003] The front beam is equipped with an upper guide plate and a lower guide plate, and the mold base assembly is locked between the upper guide plate and the lower guide plate and can slide. In the prior art, in order to stabilize the position of the mold base assembly after it has been moved into place, a clamping device is installed in the upper guide plate and the lower guide plate to press the mold base assembly onto the front beam and prevent it from shaking back and forth during operation.

[0004] However, the above-mentioned prior art has at least the following problems: 1. During operation, the temperature of the mold base assembly is high, which will have an adverse effect on the clamping device and shorten its service life; 2. The clamping device is installed in the upper guide plate or the lower guide plate, and its installation space is limited, which is not conducive to installing a larger and more powerful drive device, and is not conducive to enhancing its ability to clamp the mold base assembly.

[0022] like Figures 1 to 3 As shown, a metal extrusion press with a die holder clamping device 7 includes a front beam 1 and a die holder assembly 2 slidably connected to the front beam 1. The die holder clamping device 7 includes a first clamping device 5 and a second clamping device 6. The first clamping device 5 includes a first clamping drive device 51 and a first clamping member 52 connected by transmission. The first clamping drive device 51 is located above the die holder assembly 2, and the first clamping member 52 corresponds to the upper part of the die holder assembly 2. The second clamping device 6 includes a second clamping drive device 61 and a second clamping member 62 connected by transmission. The second clamping drive device 61 is located below the die holder assembly 2, and the second clamping member 62 corresponds to the lower part of the die holder assembly 2. When the die holder assembly 2 moves into position, the first clamping drive device 51 and the second clamping drive device 61 respectively drive the first clamping member 52 and the second clamping member 62 to clamp the die holder assembly 2 onto the front beam 1.

[0023] In this embodiment, the metal extrusion press has the first pressing drive device 51 and the second pressing drive device 61 respectively located above and below the die base assembly 2, so that the first pressing drive device 51 and the second pressing drive device 61 are separated from the die base assembly 2 by a certain distance. This makes the first pressing drive device 51 and the second pressing drive device 61 less affected by high temperature when the metal extrusion press is working, thereby ensuring the normal operation of the first pressing device 5 and the second pressing device 6 and extending their service life.

[0024] Specifically, the front beam 1 is provided with a cylinder mounting plate 10, and the cylinder mounting plate 10 is provided with a drive cylinder 9 for driving the mold base assembly 2. The cylinder mounting plate 10 is located at one end of the mold base assembly 2. The cylinder mounting plate 10 is provided with a limiting bolt, which protrudes from the side of the cylinder mounting plate 10 near the mold base assembly 2. When the mold base 21 moves toward the cylinder mounting plate 10 and abuts against the limiting bolt, that is, when the above-mentioned "mold base assembly 2 moves into place", the first pressing device 5 and the second pressing device 6 press the mold base assembly 2.

[0025] In some specific embodiments, reference is made to Figures 1 to 3The front beam 1 is provided with an upper guide plate 3 and a lower guide plate 4. A 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 groove 11 and can move along the groove 11. The first pressing drive device 51 and the second pressing drive device 61 are respectively provided on the upper side of the upper guide plate 3 and the lower side of the lower guide plate 4.

[0026] Placing the first clamping drive device 51 in a relatively open space above the upper guide plate 3 allows for the installation of a larger first clamping drive device 51, providing greater power to the clamping mold base assembly 2. Similarly, placing the second clamping drive device 61 in a relatively open space below the lower guide plate 4 allows for the installation of a larger second clamping drive device 61, providing greater power to the clamping mold base assembly 2.

[0027] In some other embodiments, the front beam 1 is provided with a slide rail, and the mold base assembly 2 is engaged on the slide rail and can move along the slide rail.

[0028] 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 parts of the mold base connecting seat 22 include an upper guide boss 221 and a lower guide boss 222, respectively. 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.

[0029] The "upper part of mold base assembly 2" and "lower part of mold base assembly 2" mentioned above are the upper guide boss 221 and the lower guide boss 222, respectively. The mold base assembly 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.

[0030] In some specific embodiments, reference is made to Figures 1 to 3 The first clamping member 52 is elongated. The first clamping device 5 also includes a first mounting base 53 disposed on the front beam 1 or the upper guide plate 3. The first clamping member 52 is rotatably connected to the first mounting base 53. The upper end of the first clamping member 52 is connected to the first clamping drive device 51, and the lower end of the first clamping member 52 corresponds to the position of the upper guide boss 221. The second clamping member 62 is elongated. The second clamping device 6 also includes a second mounting base 63 disposed on the front beam 1 or the lower guide plate 4. The second clamping member 62 is rotatably connected to the second mounting base 63. The lower end of the second clamping member 62 is connected to the second clamping drive device 61, and the upper end of the second clamping member 62 corresponds to the position of the lower guide boss 222.

[0031] Specifically, during operation, the first pressing drive device 51 and the second pressing drive device 61 respectively drive the upper end of the first pressing member 52 and the lower end of the second pressing member 62 to move forward, so that the lower end of the first pressing member 52 and the upper end of the second pressing member 62 move backward, thereby pressing the first pressing member 52 and the second pressing member 62 onto the mold base assembly 2.

[0032] The first clamping member 52 and the second clamping member 62 are rotatably connected to the first mounting base 53 and the second mounting base 63 respectively to form a lever structure. Even if the first clamping drive device 51 and the second clamping drive device 61 are far away from the mold base assembly 2, they can still transmit their power to the mold base assembly 2, thereby achieving the above-mentioned beneficial effects of "reducing the impact of high temperature" and "facilitating the first clamping drive device 51 and the second clamping drive device 61 with larger facility volume and power".

[0033] In some specific embodiments, reference is made to Figure 2 The upper guide plate 3 is provided with a first clearance hole 32, and the first clamping member 52 extends into the first clearance hole 32 and corresponds to the position of the upper guide boss 221; the lower guide plate 4 is provided with a second clearance hole 42, and the second clamping member 62 extends into the second clearance hole 42 and corresponds to the position of the lower guide boss 222.

[0034] The first clearance hole 32 and the second clearance hole 42 are provided to ensure that the first clamping member 52 and the second clamping member 62 do not interfere with the position of the upper guide plate 3 and the lower guide plate 4, thus ensuring the normal operation of the clamping device. In addition, the first clamping member 52 and the second clamping member 62 extending into the first clearance hole 32 and the second clearance hole 42 respectively also improve the aesthetics.

[0035] In some specific embodiments, the first pressing drive device 51 includes a first pressing cylinder or a first pressing oil cylinder, and the second pressing drive device 61 includes a second pressing cylinder or a second pressing oil cylinder.

[0036] If a hydraulic cylinder is used as the clamping drive device, in this embodiment, its exposure to high temperatures can be reduced, thereby reducing the risk of accidents such as oil leakage from the seals inside the hydraulic cylinder.

[0037] In other embodiments, other driving devices, such as a motor + lead screw and nut structure, can be used to drive the first clamping member 52 or the second clamping member 62 to move back and forth to achieve clamping of the mold base assembly 2.

[0038] 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.
