[0020] 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.

[0021] Please see Figure 1-4 As shown in the figure, an aluminum extrusion device for easy replacement of extrusion dies according to an embodiment of the present invention includes a base 1, a lower die base 10 installed at the center of the upper surface of the base 1, four support rods 2 distributed in a rectangle on the top surface of the lower die base 10, and a top plate 20 connected to the upper ends of the four support rods 2. The top plate 20 is connected to an assembly seat 3 for mounting an upper die base 30 through a drive mechanism. The front end of the assembly seat 3 is formed with an assembly slot 31, and the upper die base 30 is formed with an assembly part 32 adapted to the assembly slot 31. The assembly seat 3 has a limiting component for locking or unlocking the upper die base 30.

[0022] In use, this utility model drives the assembly base 3 and the upper mold base 30 to move closer to or away from the lower mold base 10 through the drive mechanism to achieve aluminum extrusion molding. The four support rods 2 are distributed in a rectangular shape to ensure the overall stability of the equipment. The upper mold base 30 can be disassembled as needed for daily maintenance or replacement. The limiting component is used to lock or unlock the upper mold base 30. It is simple to operate and highly practical.

[0023] The limiting component includes two pivots 4 correspondingly disposed at the front opening end of the mounting slot 31. The pivot 4 includes a smooth section 40 at the inner end and a threaded section 41 at the outer end. A limiting baffle 42 is movably sleeved on the outer ring of the smooth section 40. A knob 43 for fixing the limiting baffle 42 is threadedly connected to the outer end of the threaded section 41.

[0024] In use, the limiting component has a locked state or an unlocked state. In the unlocked state, the limiting baffle 42 is controlled to rotate along the pivot 4 so that it is set horizontally. At this time, the limiting baffle 42 will not block the upper mold base 30 from entering and exiting the assembly slot 31. In the locked state, the limiting baffle 42 is controlled to rotate along the pivot 4 so that it is set vertically. In the above states, the limiting baffle 42 forms a limiting block on the upper mold base 30 housed in the assembly slot 31 to lock the upper mold base 30. The locking or unlocking of the limiting baffle 42 is achieved by tightening or loosening the knob 43.

[0025] When installing the upper mold base 30, switch the limiting component to the unlocked state, align and push the assembly part 32 of the upper mold base 30 with the assembly slot 31 of the assembly base 3 until the inner end of the assembly part 32 fits against the inner side of the assembly slot 31, and then switch the limiting component to the locking mode to achieve limiting and locking of the upper mold base 30.

[0026] The limiting baffle 42 has arc-shaped grooves 44 formed at both ends of the mating side with the assembly slot 31. The front end of the assembly base 3 has three receiving holes 45 arranged in a triangular shape on the rotation path of the two arc-shaped grooves 44. Each receiving hole 45 is provided with a positioning member 46 that is adapted to the arc-shaped groove 44. The outer end of the positioning member 46 is formed with an arc-shaped part that is adapted to the arc-shaped groove 44. A spring member 47 is fixedly connected between the inner end of the positioning member 46 and the inner bottom wall of the receiving hole 45.

[0027] When using, please refer to the instruction manual attached. Figure 3 At this time, the limiting baffle 42 is in the locked state, and one of the arc grooves 44 and the positioning member 46 of one of the receiving holes 45 form a pre-position, so that it remains in the locked state; when the limiting baffle 42 is in the unlocked state, the two arc grooves 44 and the other two corresponding arc grooves 44 form a pre-position, so that it remains in the unlocked state.

[0028] The positioning element 46 in the three receiving holes 45 cooperates with the two arc grooves 44 on the inner side of the limiting plate 42, so that the limiting plate 42 can quickly reach the preset position and be pre-positioned when switching states. Finally, tightening the knob 43 completes the final locking of the use state of the limiting plate 42.

[0029] The two ends of the spring member 47 are fixedly connected to the inner bottom wall of the receiving hole 45 and the inner end face of the positioning member 46, respectively. In the initial state, the spring member 47 causes the positioning member 46 to extend out of the receiving hole 45. The pre-positioning of the limiting plate 42 is achieved through the cooperation between the arc-shaped part and the arc-shaped groove 44. When the limiting plate 42 switches to a different state, the operator only needs to apply a force to overcome the action of the spring member 47 to cause the positioning member 46 to retract toward the receiving hole 45 and exit the current arc-shaped groove 44. When the limiting plate 42 reaches the next state, the positioning member 46 pops out again and enters the corresponding arc-shaped groove 44 due to the release of the stored energy of the spring member 47.

[0030] The front end of the limiting baffle 42 has a force block 48.

[0031] In use, the force block 48 is set to provide a force point for the state switching of the limit baffle 42.

[0032] Several ball bearings 33 are movably embedded in the inner walls of the left and right sides of the assembly slot 31.

[0033] In use, the ball bearing 33 allows the upper mold base 30 to move more smoothly into and out of the assembly slot 31.

[0034] The drive mechanism includes a hydraulic cylinder 21 fixedly mounted on the upper surface of the top plate 20. The output shaft of the hydraulic cylinder 21 extends through to the bottom of the top plate 20 and is drivenly connected to the mounting base 3.

[0035] In use, the hydraulic cylinder 21 drives the assembly base 3 and the upper mold base 30 to move up and down reciprocally. Furthermore, two guide pillars are provided on the upper surface of the assembly base 3, and the top plate 20 is provided with guide sleeves at the corresponding positions of the two guide pillars. The cooperation between the guide sleeves and the guide pillars improves the movement stability of the assembly base 3 and the upper mold base 30, so that the upper mold base 30 and the lower mold base 10 can be closed stably and smoothly.

[0036] The lower mold base 10 is formed with a mold groove 11. The top surface of the lower mold base 10 is formed with two mating grooves 12 on the left and right sides of the mold groove 11, and the mating grooves 12 have built-in buffers 13. The upper mold base 30 has mating blocks 34 on the left and right sides that are compatible with the mating grooves 12.

[0037] In use, the mating block 34 works in conjunction with the mating groove 12 to increase the stability of the mold closing process. The buffer 13 (spring buffer) added inside the mating groove 12 buffers the mating block 34 when it is mated, effectively extending the service life of the upper mold base 30 and the lower mold base 10. The structure and working principle of the buffer 13 are existing technologies and will not be described in detail here.

[0038] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0039] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.
