Technical Field
[0001] This utility model relates to the field of extrusion die technology, and in particular to an extrusion die with heat preservation function. Background Technology
[0002] Extrusion molds are a type of forming mold, except that they discharge material through the extrusion process. They are widely used in aluminum profiles and plastic parts. At the front end of an extruder, they are used to make pipes or profiles. In short, a mold is a tool used to shape objects. This tool is composed of various parts, and different molds are composed of different parts.

[0033] A disassembly assembly is provided at the bottom of the mold body 1. The disassembly assembly includes a mounting groove 18 and a mounting plate 19. The mounting groove 18 is formed on the lower surface of the mold body 1, and the mounting plate 19 is provided on the lower surface of the mold body 1. The discharge groove 3 is formed through the mounting plate 19 and the mounting block 20. The mounting block 20 is fixedly mounted on the upper surface of the mounting plate 19. A sealing ring 21 is sleeved on the outer surface of the mounting block 20.

[0034] By setting the mounting slot 18, mounting plate 19, mounting block 20, sealing ring 21, limiting block 22, mounting frame 23 and mounting bolt 24, the shape of the discharge slot 3 can be changed quickly and conveniently. By replacing the mounting plate 19 and mounting block 20 with the discharge slot 3, the shape of the discharge slot 3 can be changed quickly, improving the convenience and practicality of the extrusion die.
[0035] Working principle: When installing the insulation sleeve 5 onto the extrusion mold, first bring the insulation sleeve 5 with the connecting block 8 close to the mold body 1, so that the locking block 6 is aligned with the locking groove 7. Move the insulation sleeve 5 so that the inner wall of the insulation sleeve 5 slides against the outer wall of the mold body 1, and the locking block 6 slides inside the locking groove 7. When the insulation sleeve 5 is completely fitted onto the outer surface of the mold body 1, tighten the positioning bolt 9 on the insulation sleeve 5 so that the positioning bolt 9 penetrates the outer wall of the insulation sleeve 5 and rotates into the outer surface of the mold body 1 to fix the insulation sleeve 5. Then take out the insulation sleeve 5 with the connecting groove and repeat the above operation to fix the insulation sleeve 5 and insert the connecting block 8 into the inside of the connecting groove, so that the two insulation sleeves 5 are connected to the mold body 1 and also connected to each other.
[0036] After both insulation sleeves 5 are connected to the outer surface of the mold body 1, pull the connecting rod 13 on the front wall of the insulation sleeve 5 to rotate towards the fixed plate 11, so that the rotating rod 12 rotates on the inner wall of the fixed seat 10. When the connecting rod 13 slides into the inside of the groove, rotate the rotating ring 17 to drive the rotating cylinder 16 to rotate on the side wall of the pressure plate 14. With the cooperation of the internal and external threads, the rotating cylinder 16 drives the pressure plate 14 to move on the outer surface of the connecting rod 13. Under the action of the sliding cylinder 15, the pressure plate 14 moves towards the fixed plate 11. When the sliding cylinder 15 and the rotating cylinder 16 slide into the inside of the groove, the pressure plate 14 contacts the side wall of the fixed plate 11. The pressure plate 14 presses the fixed plate 11 to reinforce the front end of the insulation sleeve 5. Repeat the above operation to reinforce the rear end of the insulation sleeve 5, and complete the installation of the insulation sleeve 5.
[0037] When it is necessary to change the shape of the discharge trough 3, first tighten the mounting bolt 24 so that the mounting bolt 24 extends away from the mounting frame 23. After the mounting bolt 24 separates from the mounting plate 19, release the fixing of the mounting plate 19. Then, pull the mounting plate 19 by the handle. The mounting plate 19 slides inside the mounting frame 23, so that the mounting plate 19 drives the mounting block 20 to slide outward from the inside of the mounting groove 18. After the mounting block 20 slides out of the inside of the mounting groove 18, take out the mounting plate 19 and the mounting block 20 with different shaped discharge troughs 3, and reverse the above operation to install the mounting plate 19 and the mounting block 20 onto the mold body 1 to complete the change of the shape of the discharge trough 3.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
