[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] Please refer to Figure 1 - Figure 5, the present utility model provides an extrusion die disassembly device, including a U-shaped lifting frame 1. At the center of the bottom surface of the U-shaped lifting frame 1, a lifting cross plate 11 is fixedly connected. Below one end of the lifting cross plate 11, a first disassembly sleeve 2 is provided. Inside the first disassembly sleeve 2, three iron rod through holes 21 are opened. The three iron rod through holes 21 are equally angularly arranged along the outer peripheral direction of the first disassembly sleeve 2. Inside each of the three iron rod through holes 21, an iron rod ejector rod 22 is slidably penetrated. One end of each of the three iron rod ejector rods 22 is perpendicularly fixedly connected to one end of the bottom surface of the lifting cross bar. Below the other end of the lifting cross plate 11, a second disassembly sleeve 3 is provided. Inside the second disassembly sleeve 3, three fitting through holes 31 are opened. The three fitting through holes 31 are equally angularly arranged along the outer peripheral direction of the second disassembly sleeve 3. Between the inner walls of the three fitting through holes 31, a fitting ejector rod 32 is installed through. One end of each of the three fitting ejector rods 32 is perpendicularly fixedly connected to the other end of the bottom surface of the lifting cross bar. The lower openings of the first disassembly sleeve 2 and the second disassembly sleeve 3 are both clamped with a die body 4. The openings of the two die bodies 4 are respectively located at the lower projections of the iron rod ejector rod 22 and the fitting ejector rod 32. Below both of the two die bodies 4, support sleeves 5 are provided. On the top surfaces of the two support sleeves 5, limit rings 51 are opened. The inner walls of the two limit rings 51 respectively fit with the lower outer walls of the two die bodies 4. The U-shaped lifting frame 1 installs the iron rod ejector rod 22 and the fitting ejector rod 32 through the lifting cross plate 11. The iron rod ejector rod 22 and the fitting ejector rod 32 are respectively slidably sleeved inside the iron rod through holes 21 and the fitting through holes 31 of the first disassembly sleeve 2 and the second disassembly sleeve 3. After the U-shaped lifting frame 1 is installed, the un-pressed die body 4 is placed below the iron rod ejector rod 22 and fits with the limit ring 51 at the top of the support sleeve 5, and the through hole of the die body 4 is made to correspond to the iron rod ejector rod 22 through marking. At this time, the lower groove of the first disassembly sleeve 2 fits with the upper opening of the die body 4. Then, the hydraulic rod is pressed down to realize the primary extrusion of the die body 4. After the hydraulic cylinder is restored, the pressed die body 4 is placed on another support sleeve 5, and an un-pressed die body 4 is re-filled on the support sleeve 5 below the iron rod ejector rod 22. At this time, a die body 4 that has been de-aluminized can be obtained through stamping, and the above steps are repeated, so that one die body 4 that has been de-aluminized can be obtained by the hydraulic rod stamping two die bodies 4 at a time;

[0027] As Figure 3 and Figure 4As shown, a horizontally placed limiting frame 6 is clamped between the two mold bodies 4 and the seam of the disassembly sleeve. Both ends of the horizontally placed limiting frame 6 are fixedly connected with frame sliders 61. The outer walls of the two frame sliders 61 are sleeved with mounting frames 7. The frame slider 61 is fixedly connected with a spring 62 at the end away from the opening of the horizontally placed limiting frame 6. One end of the spring 62 is fixedly connected with the inner wall of one end of the mounting frame 7. The horizontally placed limiting frame 6 is clamped with the top seam of the mold body 4. Since it is matched with the mounting frame 7 through the frame slider 61 and the mounting frame 7 is installed on the processing surface, when the iron rod ejector 22 and the fitting ejector rod 32 move upward along with the hydraulic rod, the mold body 4 will not move accordingly, and it cooperates to discharge the aluminum block inside. When replacing the mold body 4, push the horizontally placed limiting frame 6 to overcome the elastic force of the spring 62, so that the upper bayonet of the horizontally placed limiting frame 6 will not obstruct the process of replacing the mold body 4;

[0028] As Figure 1 and Figure 2 shown, limiting through holes 12 are opened at both ends of the U-shaped lifting frame 1. The axes of the two limiting through holes 12 are collinear. Limiting brackets 13 are symmetrically fixedly connected to the side walls at both ends of the U-shaped lifting frame 1. A limiting clamping rod 8 slides through the inner walls of the limiting through holes 12. A clamping rod through hole 81 is opened on the outer wall of one end of the limiting clamping rod 8. A T-shaped frame 9 slides through the inner walls of the clamping rod through hole 81. One end of the T-shaped frame 9 slides through the through hole of the limiting bracket 13. When the limiting clamping rod 8 passes through the limiting through hole 12 and is clamped with the side groove of the hydraulic cylinder, the whole U-shaped lifting frame 1 can move up and down following the telescopic movement of the hydraulic rod, and the T-shaped frame 9 passing through the clamping rod through hole 81 and the limiting bracket 13 can prevent the limiting clamping rod 8 from disengaging during this process, increasing the structural rationality of the device;

[0029] Working principle: when the limit clamp rod 8 passes through the limit through hole 12 and is clamped with the side groove of the hydraulic cylinder, the U-shaped lifting frame 1 as a whole can move up and down with the extension and contraction of the hydraulic lever, and the T-shaped frame 9 passes through the clamp rod through hole 81 and the limit bracket 13 to prevent the limit clamp rod 8 from detaching during the process. The U-shaped lifting frame 1 installs the iron rod top rod 22 and the matching top rod 32 through the lifting cross plate 11, and the iron rod top rod 22 and the matching top rod 32 are slidably sleeved in the iron rod through hole 21 and the matching through hole 31 in the first disassembly sleeve 2 and the second disassembly sleeve 3, respectively. After the U-shaped lifting frame 1 is installed, the mold body 4 that has not been stamped is placed under the iron rod top rod 22 to fit with the top limit ring 51 of the support sleeve 5, and the through hole of the mold body 4 is marked to correspond to the iron rod top rod 22. At this time, the groove below the first disassembly sleeve 2 fits with the upper opening of the mold body 4, and then the hydraulic cylinder is pressed down to realize the mold After the initial extrusion of the main body 4, the hydraulic cylinder is restored to place the punched mold body 4 on another support sleeve 5, and the unpunched mold body 4 is reinstalled on the support sleeve 5 below the iron rod push rod 22. At this time, a mold body 4 with aluminum removed can be obtained after stamping, and the above steps are repeated so that the hydraulic lever can punch two mold bodies 4 at a time to obtain a mold body 4 with aluminum removed. The horizontal limit frame 6 is clamped with the top seam of the mold body 4. Since it cooperates with the mounting frame 7 through the frame slider 61, the mounting frame 7 is installed on the processing surface. Therefore, when the iron rod push rod 22 and the matching push rod 32 move up with the hydraulic lever, the mold body 4 will not move therewith, and the aluminum block inside it will be discharged. When the mold body 4 is replaced, the horizontal limit frame 6 is pushed to overcome the elastic force of the spring 62, so that the clamping mouth on the horizontal limit frame 6 will not hinder the process of replacing the mold body 4.

[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
