[0017] Example, as shown in Figures 1 to 3As shown in the figure, a metal part hole plastic sleeve extrusion die mechanism includes a die base 10. In the middle of the top surface of the top plate of the die base 10, a lower adjusting frame 11 is fixed. In the middle of the top surface of the top plate of the lower adjusting frame 11, an upper placing die seat 12 is fixed. The metal part 100 to be processed is inserted into the top of the upper placing die seat 12. The metal part 100 includes a top plate, and downwardly extending side parts are formed on the bottom surfaces of the four sides of the top plate. The bottom surface of the top plate of the metal part 100 is pressed against the top surface of the top plate of the upper placing die seat 12, and the side parts are closely attached to the outer side walls of the upper placing die seat 12;

[0018] In the middle of the left and right parts of the bottom surface of the top plate of the metal part 100, a plurality of downwardly extending sleeve parts 101 are formed. In this embodiment, two sleeve parts 101 are formed in the middle of the left and right parts of the bottom surface of the top plate of the metal part 100;

[0019] The sleeve parts 101 are inserted into the corresponding vertical through holes 13 on the top plate of the upper placing die seat 12, and the top ends of the middle through holes of the sleeve parts 101 extend out of the top surface of the top plate of the metal part 100;

[0020] On the left and right parts of the top surface of the top plate of the die base 10, a plurality of support columns are fixed. The main top plate 14 is fixed on the top surfaces of all the support columns. The main top plate 14 is located above the metal part 100. On the left and right parts of the middle of the top surface of the main top plate 14, pressing oil cylinders 15 are fixed. The bottom ends of the push rods of the pressing oil cylinders 15 extend out of the bottom surface of the main top plate 14 and are fixed on the top surface of the same horizontal fixing plate 16;

[0021] A pressing plate 17 is arranged below the horizontal fixing plate 16. On the left, middle and right parts of the top surface of the pressing plate 17, a plurality of vertical guiding rods 171 are fixed. The vertical guiding rods 171 are inserted into the corresponding vertical through holes on the horizontal fixing plate 16, and the top ends of the vertical guiding rods 171 extend out of the corresponding through holes on the main top plate 14. A guiding sleeve 141 is clamped on the inner side wall of the through hole on the main top plate 14, and the vertical guiding rods 171 are inserted into the corresponding guiding sleeves 141, and the outer side walls of the vertical guiding rods 171 are closely attached to the inner side walls of the corresponding guiding sleeves 141. A pressing spring 1 is inserted on the vertical guiding rods 171. The top end of the pressing spring 1 acts on the bottom surface of the horizontal fixing plate 16, and the bottom end of the pressing spring 1 acts on the top surface of the pressing plate 17. On the left and right parts of the middle of the bottom surface of the pressing plate 17, a plurality of protruding clamping parts 172 (two protruding clamping parts 172 in this embodiment) are fixed. The top of the plastic sleeve 200 is clamped on the outer side wall of the corresponding protruding clamping part 172. The bottom end of the plastic sleeve 200 faces the middle through hole of the corresponding sleeve part 101.

[0022] Furthermore, the outer side wall of the sleeve part 101 is closely attached to the inner side wall of the corresponding vertical through hole 13.

[0023] Furthermore, the bottom end of the sleeve part 101 extends out of the bottom end of the corresponding vertical through hole 13. A plurality of vertical screw connection through holes are formed on the top plate of the lower adjusting frame 11. The adjusting screw 20 is screwed in the corresponding vertical screw connection through hole. The bottom end of the adjusting screw 20 extends out of the bottom surface of the top plate of the lower adjusting frame 11 and is fixed with a rotating part. The top end of the adjusting screw 20 extends out of the top surface of the top plate of the lower adjusting frame 11 and is fixed with a bottom support plate 21. The top surface of the bottom support plate 21 faces the bottom end surface of the corresponding sleeve part 101.

[0024] Furthermore, a buffer spring 22 is inserted on the adjusting screw 20. The bottom end of the buffer spring 22 bears on the bottom surface of the top plate of the lower adjusting frame 11, and the top end of the buffer spring 22 bears on the bottom surface of the corresponding bottom support plate 21.

[0025] When this embodiment is in use, first place the metal part 100 on the top plate of the upper placement mold base 12, so that the sleeve part 101 is inserted into the corresponding vertical through hole 13 on the top plate of the upper placement mold base 12, and the outer side wall of the sleeve part 101 is closely attached to the inner side wall of the corresponding vertical through hole 13. Then, rotate all the adjusting screws 20 so that the top surface of the bottom support plate 21 presses against the bottom surface of the sleeve part 101, ensuring that the bottom end of the subsequent plastic sleeve 200 will not extend out of the bottom end surface of the sleeve part 101 after being clamped to the corresponding sleeve part 101;

[0026] Then, clamp the top of the plastic sleeve 200 to be processed on the outer side wall of the corresponding convex clamping part 172. Then, through the pushing of the push rods of the two pressing oil cylinders 15, the horizontal fixing plate 16 descends, driving the pressing plate 17 to press down, and clamping the plastic sleeve 200 into the middle through hole of the corresponding sleeve part 101. When pressing, due to the buffering effect of the pressing spring 1, the pressing plate 17 has a buffering effect when pressing down, reducing the impact force and ensuring the pressing effect of the plastic sleeve 200.

[0027] After the pressing is completed, the push rods of the two pressing oil cylinders 15 retract. At this time, since the frictional force between the plastic sleeve 200 and the inner side wall of the middle through hole of the sleeve part 101 is greater than the frictional force between the top of the plastic sleeve 200 and the outer side wall of the corresponding convex clamping part 172, when the push rods of the two pressing oil cylinders 15 retract, the plastic sleeve 200 and the convex clamping part 172 are separated, realizing the fixed installation between the metal part 100 and the plastic sleeve 200;

[0028] Subsequently, it only needs to be taken out. All the plastic sleeves 200 can be installed on the metal part 100 with one pressing. Its processing effect is good and it is very convenient.

[0029] The above embodiments are only used to illustrate the present utility model, rather than to limit the present utility model. Those of ordinary skill in the relevant technical field can also make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also belong to the scope of the present utility model. The patent protection scope of the present utility model shall be defined by the claims.
