[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] likeFigure 1 , Figure 2 As shown, this utility model provides a quick-change device for aluminum profile extrusion dies, including a U-shaped placement plate 1, an extrusion die 2 disposed on the inner side of the U-shaped placement plate 1, an adjusting base 3 disposed at the bottom of the U-shaped placement plate 1, a fixed horizontal plate 11 fixedly installed above the two vertically opposite faces of the U-shaped placement plate 1, the fixed horizontal plate 11 having a vertically penetrating lifting threaded hole 111, a lifting threaded rod 12 threaded into the inner ring of the lifting threaded hole 111, a rotating disk 121 fixedly installed at the top of the lifting threaded rod 12, and a connecting plate 122 movably installed at the bottom end of the lifting threaded rod 12. Both ends of the 122 are fixedly installed with pressing cylinders 13. The outer walls of the pressing cylinders 13 are fixedly bonded with rubber sleeves 131. The outer walls of the two rubber sleeves 131 overlap with the top of the extrusion mold 2. The two vertical parts of the U-shaped placement plate 1 are provided with left and right through sliding grooves 14. The inner walls of the two sliding grooves 14 are fixedly installed between the upper and lower sides. The top left and right sides of the connecting plate 122 are fixedly installed with limiting slide plates 123. The two limiting slide plates 123 are respectively located above the two pressing cylinders 13. The two limiting slide plates 123 are slidably connected to the two slide rods 141 respectively.

[0023] During installation, the extrusion mold 2 is placed inside the U-shaped placement plate 1. Then, by rotating the rotating disk 121 above the fixed horizontal plate 11, the lifting threaded rod 12 rotates and descends in the inner ring thread of the lifting threaded hole 111. The bottom end of the lifting threaded rod 12 is connected to the connecting plate 122 to control the downward movement of the connecting plate 122 and the pressing cylinders 13 at both ends. The stability of the pressing cylinder 13's up and down movement is maintained by the sliding of the two limiting slide plates 123 on the outer wall of the slide rod 141 in the slide groove 14. Finally, the rubber sleeve 131 on the outer wall of the pressing cylinder 13 presses the top of the extrusion mold 2 to fix the up and down direction of the extrusion mold 2.

[0024] like Figure 3 As shown, the U-shaped placement plate 1 has a clamping drive chamber 15. A servo motor 16 is fixedly installed on the rear side of the U-shaped placement plate 1. The output shaft of the servo motor 16 passes through the inner cavity of the clamping drive chamber 15 and is fixedly installed with a positive and negative threaded rod 161. The outer walls of the positive and negative threaded rod 161 have opposite threaded walls on the front and rear sides respectively. The outer walls of the two threaded walls are threaded with movable plates 162. Movable upright plates 163 are fixedly installed on the top left and right sides of the two movable plates 162. Two clamping movable slots 18 are opened at the top of the horizontal position of the U-shaped placement plate 1, which pass through the inner cavity of the clamping drive chamber 15. The two movable upright plates 163 pass through the two clamping movable slots 18 to the top of the horizontal position of the U-shaped placement plate 1. An adjusting clamping mechanism 17 is provided between the opposite surfaces of the two movable upright plates 163 at the top of the two movable plates 162.

[0025] By activating the servo motor 16 on the rear side of the U-shaped placement plate 1, the positive and negative threaded rods 161 inside the clamping drive chamber 15 can be rotated. The threaded walls of the opposite threads on the front and rear sides of the outer wall of the positive and negative threaded rods 161 are connected to the threads of the moving plate 162, which controls the movement of the two moving upright plates 163 on the top of the two moving plates 162 inside the clamping moving groove 18. Finally, the adjusting clamping mechanism 17 is driven to clamp and fix the front and rear sides of the extrusion mold 2, thus completing the installation of the extrusion mold 2. When the extrusion mold 2 needs to be replaced, simply reverse the rotating disk 121 to drive the pressing cylinder 13 to rise, and at the same time start the output shaft of the servo motor 16 to reverse so that the two adjusting clamping mechanisms 17 are away from the extrusion mold 2. Thus, the extrusion mold 2 can be directly removed and replaced without the need for tools to fix the extrusion mold 2.

[0026] like Figure 4 , Figure 5 As shown, both adjusting clamping mechanisms 17 include a connecting horizontal plate 171, which is fixedly installed between the opposite faces of the two movable vertical plates 163. Both connecting horizontal plates 171 have through-holes 172. Adjusting threaded rods 173 are threaded onto the inner rings of both threaded holes 172. Arc-shaped clamping plates 174 are movably installed at the opposite ends of the two adjusting threaded rods 173. Knobs 175 are fixedly installed at the ends of the two adjusting threaded rods 173 away from the arc-shaped clamping plates 174. The two arc-shaped clamping plates 174 are located on the front and rear sides of the extrusion die 2, respectively. The opposite sides of the two arc-shaped clamping plates 174 are... A limiting slide rod 176 is fixedly installed, and the limiting slide rod 176 is slidably connected to the connecting horizontal plate 171. The left and right sides of the adjusting base 3 are fixedly installed with mounting side plates 31. The top of the adjusting base 3 is provided with an adjusting groove 32. An adjusting threaded rod 321 is movably installed on the right side of the inner wall of the adjusting groove 32. The left end of the adjusting threaded rod 321 extends through to the left side of the adjusting base 3 and is fixedly installed with a rotating handle 323. An adjusting block 322 is threadedly installed on the outer wall of the adjusting threaded rod 321. The front and rear sides of the adjusting block 322 overlap with the front and rear sides of the inner wall of the adjusting groove 32, respectively. The top of the adjusting block 322 is fixedly connected to the bottom of the U-shaped placement plate 1.

[0027] When it is necessary to adjust the front and back position of the extrusion die 2 within the U-shaped placement plate 1, simply rotate the knob 175 included in the front or rear adjustment clamping mechanism 17 separately in advance. This will cause the adjusting threaded rod 173 to rotate within the threaded hole 172, allowing the arc clamping plate 174 to move stably towards the extrusion die 2 via the sliding connection between the limiting slide rod 176 and the connecting horizontal plate 171. Since the position of the arc clamping plate 174 included in the other adjustment clamping mechanism 17 remains unchanged, the position of the extrusion die 2 can be adjusted front and back when the two arc clamping plates 174 clamp and fix the extrusion die 2. At the same time, the overall adjustment base 3 can be fixed to the extruder by bolts passing through the mounting side plate 31. By rotating the rotating handle 323, the adjusting threaded rod 321 in the adjustment groove 32 can be rotated. The U-shaped placement plate 1 installed on the top of the adjusting block 322 can be adjusted left and right by the threaded connection between the adjusting block 322 and the adjusting threaded rod 321, so that the extrusion die 2 can be adjusted even in a fixed state.

[0028] The working principle of this quick-change device for aluminum profile extrusion dies will be explained in detail below.

[0029] like Figures 1-5As shown, during installation, the extrusion mold 2 is placed inside the U-shaped placement plate 1. Then, by rotating the rotating disk 121 above the fixed horizontal plate 11, the lifting threaded rod 12 rotates and descends within the lifting threaded hole 111. The movable connection between the bottom end of the lifting threaded rod 12 and the connecting plate 122 controls the downward movement of the connecting plate 122 and the pressing cylinders 13 at both ends. The stability of the pressing cylinders 13's vertical movement is maintained by the sliding of the two limiting slide plates 123 on the outer wall of the slide rod 141 within the slide groove 14. Finally, the rubber sleeve 131 on the outer wall of the pressing cylinder 13 presses the top of the extrusion mold 2. The extrusion mold 2 is fixed vertically. Then, by activating the servo motor 16 on the rear side of the U-shaped placement plate 1, the positive and negative threaded rods 161 inside the clamping drive chamber 15 can be rotated. By connecting the threaded walls of the opposite threads on the front and rear sides of the outer wall of the positive and negative threaded rods 161 with the threads of the moving plates 162, the two moving upright plates 163 on the top of the two moving plates 162 can be controlled to move inside the clamping moving groove 18. Finally, the adjusting clamping mechanism 17 is driven to clamp and fix the front and rear sides of the extrusion mold 2, completing the installation of the extrusion mold 2. When the extrusion mold 2 needs to be replaced, simply reverse the rotating disk 121 to drive the clamping. As cylinder 13 rises, the output shaft of servo motor 16 reverses, causing the two adjusting clamping mechanisms 17 to move away from extrusion mold 2. This allows extrusion mold 2 to be directly removed and replaced without the need for tools to fix it. When adjusting the front-to-back position of extrusion mold 2 within the U-shaped placement plate 1, simply rotate the knob 175 included in the front or rear adjusting clamping mechanism 17 individually. This will cause the adjusting threaded rod 173 to rotate within the threaded hole 172, causing the arc-shaped clamping plate 174 to move stably towards the extrusion mold 2 via the sliding connection between the limiting slide rod 176 and the connecting horizontal plate 171. Due to the other... The position of the arc clamping plate 174 included in the side adjustment clamping mechanism 17 remains unchanged. Therefore, when the two arc clamping plates 174 clamp and fix the extrusion mold 2, the position of the extrusion mold 2 can be adjusted back and forth. At the same time, the overall adjustment base 3 can be fixed to the extruder by bolts passing through the mounting side plate 31. By rotating the rotating handle 323, the adjustment threaded rod 321 in the adjustment groove 32 can be rotated. The U-shaped placement plate 1 installed on the top of the adjustment block 322 can be adjusted in the left and right directions by the threaded connection between the adjustment block 322 and the adjustment threaded rod 321, so that the extrusion mold 2 can be adjusted even in the fixed state.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
