[0020] The utility model provides a horizontal aluminum profile extrusion die inner cavity polishing device, which solves the problems of low polishing efficiency and difficulty in achieving uniform surface roughness of the working belt in the prior art solutions, and realizes mechanical polishing of the die inner cavity in the form of horizontal equipment, thereby improving the polishing efficiency and effect.

[0021] See also Figure 1 , Figure 2 , a horizontal aluminum profile extrusion die inner cavity polishing device according to one embodiment of the utility model comprises a front pressing block 1 and a rear pressing block 2, the front pressing block 1 has a through abrasive inlet, the rear pressing block 2 has a through abrasive outlet, a mold pressing and positioning space for accommodating a mold 9 is formed between the front pressing block 1 and the rear pressing block 2, the mold 9 has a through inner cavity (mold hole), and the height positions of the abrasive inlet, the mold hole, and the abrasive outlet are substantially flush. The front pressing block 1 and / or the rear pressing block 2 are connected to a pressing drive mechanism, so that the front pressing block 1 and the rear pressing block 2 can be opened and closed, so as to perform the pressing positioning and release of the mold 9. An extrusion barrel 3 is connected to the side of the front pressing block 1 facing away from the rear pressing block 2, the extrusion barrel 3 is connected to an extrusion cylinder 4, the interior of the extrusion barrel 3 is connected to the abrasive inlet, and the interior of the extrusion barrel 3 has viscous abrasive 5. Thus, the viscous abrasive 5 can be extruded, passed through the inner cavity of the mold 9, and the inner wall can be polished. The extrusion cylinder 4 is, for example, an oil cylinder, and the extrusion barrel 3 has an extrusion rod 24 and an extrusion sleeve 25. A recovery barrel 6 is connected to the side of the rear pressing block 2 facing away from the front pressing block 1, and the interior of the recovery barrel 6 is connected to the abrasive outlet. Thus, the recovery barrel 6 can collect the extruded viscous abrasive 5 at the rear, and then can be recycled.

[0022] More specifically, the horizontal aluminum profile extrusion die inner cavity polishing equipment has a frame 27 for arranging various components, and angle irons 26 are provided at multiple locations on the frame 27 to further ensure the stability of the beam frame structure. A limiting slide 7 is provided below the mold pressing and positioning space, and the limiting slide 7 is fixedly mounted on the frame 27. One end of the limiting slide 7 extends outside the mold pressing and positioning space, and the limiting slide 7 is slidably connected to a moving slider 8, and a mold seat 10 for placing a mold 9 is provided on the moving slider 8. Therefore, the mold seat 10 can slide in and out of the mold pressing and positioning space, and when outside the mold pressing and positioning space, there is enough space to move the mold 9 out of the horizontal aluminum profile extrusion die inner cavity polishing equipment.

[0023] Furthermore, it also includes a mold moving motor 11, and the mold moving motor 11 is driven and connected to a mold moving screw 12. The limiting slide 7 is linear, and the length direction of the mold moving screw 12 is parallel to the length direction of the limiting slide 7. The moving slider 8 or the mold seat 10 is provided with a through slider threaded hole, and the mold moving screw 12 is threadedly connected to the slider threaded hole in a matching manner. Thus, it is driven by a threaded matching method, and this method has a strong and stable driving force. Preferably, both ends of the limiting slide 7 have baffles 13, and the mold moving screw 12 is rotatably connected to the baffles 13, for example, by bearings; thereby ensuring the stability of the mold moving screw 12 and effectively limiting the moving slider 8. It can be imagined that in other embodiments, the limiting slide 7 and the like adopt other driving methods such as hydraulic / pneumatic / electric.

[0024] More preferably, if Figure 1 As shown, the limiting chute 7 is located between the front pressing block 1 and the rear pressing block 2, and the widths of the limiting chute 7, the moving slider 8, and the mold seat 10 are all smaller than the width of the mold 9. Therefore, the front pressing block 1 and the rear pressing block 2 can be made large enough to increase the contact area with the mold 9 when pressing, and the limiting chute 7 and the like are located in the middle, which does not hinder the pressing of the mold 9, and there is no need to design a very high moving slider 8 or mold seat 10 to avoid the mold pressing positioning space, which improves the space utilization rate, makes the equipment structure more compact, and makes the center of gravity of the mold 9 lower, ensuring stability.

[0025] The movable slider 8 preferably has a rotatable pulley 14, and the pulley 14 is matchedly arranged in the limiting slide groove 7; in other words, the movable slider 8 adopts a trolley-shaped structure to stably match the limiting slide groove 7 while reducing the friction during movement, making the movement smoother and avoiding jamming.

[0026] Preferably, the front pressing block 1 and the rear pressing block 2 are provided with mold pressing pads 15 on opposite sides. Of course, the mold pressing pads 15 are not provided at the abrasive inlet and abrasive outlet, and do not block the abrasive from passing through. The mold pressing pads 15 directly contact the mold 9 to increase the friction force, enhance the pressing and positioning effect, and avoid damaging the surface of the mold 9.

[0027] The clamping drive mechanism includes, for example, a clamping motor 16, which is driven by a clamping screw 17. The front clamping block 1 and / or the rear clamping block 2 are provided with a clamping block threaded hole, and the clamping screw 17 is threadedly connected to the clamping block threaded hole in a matching manner. The front clamping block 1 and / or the rear clamping block 2 having the clamping block threaded hole are also provided with a clamping block guide hole, and a guide slide 18 is slidably connected to the clamping block guide hole in a matching manner, and the length direction of the guide slide 18 is parallel to the direction from the front clamping block 1 to the rear clamping block 2. Thus, the drive is performed by threaded matching. It is conceivable that in other embodiments, the clamping drive mechanism adopts other driving methods such as hydraulic / pneumatic / electric.

[0028] Further preferably, the clamping screw 17 is a double-headed screw, and the front clamping block 1 and the rear clamping block 2 are both provided with a through clamping block threaded hole, and the two ends of the double-headed screw (with different thread directions) are respectively threadedly connected to the front clamping block 1 and the rear clamping block 2, and the front clamping block 1 and the rear clamping block 2 are both provided with a through clamping block guide hole. Therefore, as the clamping screw 17 rotates, the front clamping block 1 and the rear clamping block 2 move closer to or away from each other.

[0029] More specifically, the pressing screw 17 and the guide slide 18 are rotatably connected to the frame 27 of the horizontal aluminum profile extrusion die inner cavity polishing device through the bearing seat 19. The pressing motor 16 is drivingly connected to the pressing screw 17 through the motor reducer coupling 20, the reducer 21, and the reducer pressing screw coupling 22. Figure 1 , Figure 2 In the illustrated embodiment, only one pressing screw 17 is provided in the middle of the lower part, and two guide slide bars 18 are provided in the upper part. In other embodiments, there are two or more pressing screws 17 to provide stronger power, and the number of guide slide bars 18 can also be increased or decreased as needed, and the total number of pressing screws 17 and guide slide bars 18 is preferably at least three to ensure stability.

[0030] like Figure 1 In the illustrated embodiment, the recovery barrel 6 is basically arranged horizontally (optionally with the end slightly tilted downward), and the end of the recovery barrel 6 has an opening below and is connected to an abrasive recovery barrel 23, so that the viscous abrasive 5 can automatically fall into the abrasive recovery barrel 23. The abrasive recovery barrel 23 is preferably arranged in a detachable manner, such as a hook.

[0031] To sum up, the horizontal aluminum profile extrusion die inner cavity polishing equipment of the utility model can be applied to the inner cavity polishing process of larger and heavier aluminum profile extrusion dies. The die is compacted and positioned, and it is convenient to take and place. Polishing is performed by extruding viscous abrasives, which eliminates manual polishing, has higher work efficiency, and more uniform polishing effect. In addition, the viscous abrasives can be recycled and reused through the recycling barrel.
