The outer wall of the micro-expansion sleeve is adapted to the tapered hole, and a limiting ring groove is provided on the lower side of the tapered hole. A flange is provided on the lower outer wall of the micro-expansion sleeve, and the flange is slidably installed in the limiting ring groove. The micro-expansion sleeve is composed of a plurality of sliders, and a spring is installed between adjacent sliders; when the lower end of the micro-expansion sleeve extends out of the mold base, the sliders are opened, and when the lower end of the micro-expansion sleeve is flush with the lower end of the mold base, the sliders are closed. Its characteristics are: by arranging a tapered hole in the die base and installing a slightly expanding sleeve in the tapered hole, when the oil cylinders on both sides of the forming die push the die base, the slightly expanding sleeve moves down, and under the action of the spring, the adjacent sliders are slightly opened, so that the inner diameter of the slightly expanding sleeve increases, so that the debris cake or debris column in the forming die can be easily and quickly pushed out; its disadvantage is: since a spring is installed between adjacent sliders, when in use, metal debris can easily pass through the gap between adjacent sliders and get stuck on the spring, causing the spring to be easily damaged, and the debris on the spring is not easy to clean. When handling, it is necessary to remove the end cover and take out the slightly expanding sleeve as a whole before cleaning the iron chips and replacing the spring, which is inconvenient to use.

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] See Figure 1-9 A high-density packaging and forming device for scrap metal includes a die base 10 and a slightly expanded sliding sleeve 20. The inner hole of the die base 10 is a tapered hole 11 that is small at the top and large at the bottom. The slightly expanded sliding sleeve 20 is slidably installed in the tapered hole 11. The outer wall of the slightly expanded sliding sleeve 20 is adapted to the tapered hole 11. The slightly expanded sliding sleeve 20 is composed of a plurality of sliders 21. The sliders 21 are connected to the die base 10 through a directional sliding structure. A limiting ring 30 is installed at one end or both ends of the die base 10; when the lower end of the slightly expanded sliding sleeve 20 extends out of the bottom of the die base 10, the adjacent sliders 21 are separated from each other, and when the lower end of the slightly expanded sliding sleeve 20 is flush with the bottom of the die base 10, the adjacent sliders 21 are in contact with each other.

[0029] The sliders 21 and the die base 10 are connected by a directional sliding structure, thereby ensuring the directional sliding of each slider 21. The limiting ring 30 is used to limit the slider 21 and prevent it from separating from the die base 10. The present application eliminates the springs between adjacent sliders 21. If iron filings enter the gap, they can be blown away with an air gun. Therefore, there is no need to remove the micro-opening sleeve to clean iron filings on the spring or replace the spring, which reduces maintenance time and is more convenient to use.

[0030] See also Figure 1 、 3 When the lower end of the slightly expanded sliding sleeve 20 extends beyond the bottom of the die base 10, the adjacent sliders 21 move away from each other. At this point, the inner hole of the slightly expanded sliding sleeve 20 is at its largest, facilitating the escape of the extruded crumb cake or column within the slightly expanded sliding sleeve 20. When the slightly expanded sliding sleeve 20 moves upward, with the lower end of the slightly expanded sliding sleeve 20 flush with the bottom of the die base 10, the adjacent sliders 21 abut against each other, and the inner hole of the slightly expanded sliding sleeve 20 is at its smallest.

[0031] In this embodiment, the slightly expanded sleeve 20 is composed of 3 to 6 sliders 21.

[0032] In this embodiment, the directional sliding structure includes a directional slide groove 12 and a directional slide bar 22. The directional slide bar 22 is installed in the directional slide groove 12 and slides therewith. The directional slide groove 12 and the directional slide bar 22 are respectively installed on the inner wall of the tapered hole 11 and the outer wall of the slider 21. The directional slide groove 12 can be installed on the inner wall of the tapered hole 11 or on the outer wall of the slider 21, and the directional slide bar 22 can be installed on the outer wall of the slider 21 or on the inner wall of the tapered hole 11.

[0033] In this embodiment, see Figure 4 、 5 6. The directional slide groove 12 is a convex groove structure, and the directional slide bar 22 is a convex block structure.

[0034] In another embodiment, the directional sliding groove 12 is a dovetail sliding groove structure, and the directional sliding bar 22 is a dovetail slider structure.

[0035] In this embodiment, see Figure 2 、 3 The end face of the mold base 10 is provided with a threaded hole 13 , and the screw 31 penetrates the limiting ring 30 and then screws into the threaded hole 13 to connect and fix the limiting ring 30 to the mold base 10 .

[0036] Need to explain, combined Figure 3 The function of the limiting ring 30 is to close the directional chute 12 and prevent the directional slide bar 22 from leaving the directional chute 12. When the directional chute 12 passes through the mold base 10 from top to bottom, the limiting ring 30 needs to be installed at both ends of the mold base 10. If the directional chute 12 only passes through one end of the mold base 10, the limiting ring 30 is installed at the end that passes through. In this embodiment, the directional chute 12 passes through the lower end of the mold base 10, and the limiting ring 30 is installed at the lower end of the mold base 10. Figure 2 .

[0037] For further information, see Figure 7 、 89. A limiting notch 23 is provided on one side of each adjacent slider 21. An elastic block 24 is installed in the limiting notch 23 of the adjacent sliders 21. This reduces the depth of the gap between adjacent sliders 21, facilitating the cleaning of iron filings. Specifically, the elastic block 24 can be made of a rubber block or a silicone block. The width of the elastic block 24 is less than the depth of the limiting notch 23 between adjacent sliders 21.

[0038] The working principle or action process of the utility model is as follows:

[0039] See also Figure 1 、 3 When the lower end of the slightly expanded sleeve 20 extends out of the bottom of the mold base 10, the adjacent sliders 21 are far away from each other. At this time, the inner hole of the slightly expanded sleeve 20 is the largest, which is convenient for the debris cake or debris column extruded and formed in the slightly expanded sleeve 20 to detach. When the slightly expanded sleeve 20 moves up and the lower end of the slightly expanded sleeve 20 is flush with the bottom of the mold base 10, the adjacent sliders 21 abut against each other. At this time, the inner hole of the slightly expanded sleeve 20 is the smallest, which is convenient for squeezing the iron filings in the slightly expanded sleeve 20 into shape. When the molding device of the present application is placed on the workbench, the slightly expanded sleeve 20 will naturally move up. After extrusion molding, the slightly expanded sleeve 20 will be suspended in the air, and the debris cake or debris column in the slightly expanded sleeve 20 will be squeezed from top to bottom. The slightly expanded sleeve 20 moves down, and the inner hole becomes larger, which is convenient for demolding.
