[0026] 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.

[0027] Reference Figures 1 to 5 This utility model provides an embodiment of a quick-release extrusion die core replacement structure, including a die base 1. A cross-shaped groove is provided in the middle of the die base 1. A conveying pipe 2 is fixedly connected inside the die base 1. The conveying pipe 2 has a hollow structure inside and mainly undertakes the function of conveying extruded materials and shaping. A die core body 10 is fixedly connected to the outside of the conveying pipe 2. A limiting block 11 is fixedly connected to the outside of the conveying pipe 2. A limiting block 2 slidably connects to the outside of the conveying pipe 2. A limiting block 3 is fixedly connected to the outside of the conveying pipe 2. The limiting blocks 11, 22 and 3 are all conical. A locking head 14 is rotatably connected to the outside of the conveying pipe 2. A groove is provided on the left side of the outside of the conveying pipe 2. The locking head 14 has a groove. The locking head 14 and the groove of the conveying pipe 2 lock together. A connecting rod 15 is fixedly connected to the top of the locking head 14. A round block 16 is fixedly connected to the top of the connecting rod 15. A spring 9 is provided on the top of the round block 16.

[0028] Reference Figure 1 The mold base 1 has trapezoidal spaces on all four sides of its exterior. The trapezoidal spaces facilitate docking with other structures. The mold base 1 has multiple circular holes on its exterior. The spring 9 is slidably connected to the groove inside the mold base 1.

[0029] Reference Figure 1 , Figure 4 The mold base 1 is fixedly connected to the left and right sides of the outside with water suction pipes 4. The inside of the water suction pipes 4 is fixedly connected with a filter screen 5, which facilitates rinsing, cleaning and filtering of any overflowing materials. The left side of the outside of the water suction pipes 4 is fixedly connected with a water suction head 17. The front and rear sides of the inside of the mold base 1 are fixedly connected with flushing pipes 3. The top of the mold base 1 is fixedly connected with multiple bases 6. The top of the multiple bases 6 is connected with a column 7. The top of the column 7 is threadedly connected with a rotating shaft 8. The outside of the rotating shaft 8 is provided with a protrusion.

[0030] Working principle: When quick disassembly of the mold core body 10 is required, to prevent burns caused by overheating of the mold core body 10 after work, both the locking head 14 and the conveying pipe 2 are provided with grooves. The locking head 14 and the conveying pipe 2 are connected by locking through the grooves. Wearing protective gloves, the mold core body 10 is rotated first, so that the locking head 14 is disengaged from the conveying pipe 2. Then the mold core body 10 is pressed inward. Since the top of the round block 16 is provided with a spring 9, the locking head 14 moves outward under the force of the spring 9. The second limiting block 12 is conical in shape. The locking head 14 slides from the top of the second limiting block 12 to the bottom and finally comes to the first limiting block 11. Finally, the mold core body 10 is pulled outward. Due to the limiting effect of the first limiting block 11, when pulling outward, it slides from the top of the first limiting block 11 to the bottom until the leftmost side of the third limiting block 13. The mold core body 10 can then be directly removed.

[0031] When the temperature of the mold core body 10 is too high during operation, the flushing pipe 3 pumps cold water into the center of the cross of the mold base 1 to cool down the mold core body 10. The suction pipe 4 is equipped with a filter screen 5. The suction pipe 4 draws in the used cold water and discharges it after filtration. On the one hand, it cools down the equipment, and on the other hand, it can clean the overflowing material on the surface.

[0032] 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.
