Specific embodiments

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] The embodiments of the present invention provide a reusable female die sleeve structure, including a bottom plate 1. Exemplarily, such as Figure 1 , Figure 2 and Figure 3As shown in the figure, a base 2 is installed on the top of the bottom plate 1. Above the base 2, there is a connecting block 3. At the top edge of the base 2, several groups of electric push rods 16 are installed in a rectangular array. The output end of each group of electric push rods 16 is installed at the four corner edges of the bottom of the connecting block 3. On the top of the connecting block 3, a fixing plate 4 is installed. The top of the connecting block 3 is attached to the bottom edge of the fixing plate 4. On the top of the fixing plate 4, a fixing block 5 is installed. The fixing block 5 is located directly above the connecting block 3. On the top of the fixing block 5, a mounting plate 6 is installed. The mounting plate 6 is located directly above the fixing plate 4. At one end of the bottom of the mounting plate 6 far from the fixing block 5, a cylinder 7 is installed. The output end of the cylinder 7 is drivingly connected to an upper die cutting knife fixing rod 8. At one end of the top of the fixing plate 4 far from the fixing block 5, a cavity 9 is opened. The cavity 9 is located directly below the cylinder 7. A guide sleeve 10 is arranged in the cavity 9. The output end of the upper die cutting knife fixing rod 8 passes through the guide sleeve 10 and then an upper die cutting knife 11 is installed. The upper die cutting knife 11 is located below the fixing plate 4. At one end of the top of the base 2 far from the electric push rods 16, an empty slot 12 is opened. The empty slot 12 is located directly below the cavity 9. A cutter guide female die 13 is arranged in the empty slot 12. A cutter 14 is arranged in the cutter guide female die 13. The cutter 14 is located in the empty slot 12. A cutter gasket 15 is sleeved on the outer wall of the cutter 14. The cutter gasket 15 is located in the empty slot 12.

[0025] Working principle: When the upper die cutting knife fixing rod 8 moves downward, through the guide sleeve 10, the upper die cutting knife fixing rod 8 will push the product into the cutter to cut off the waste of the product. The product falls from the cavity of the cutter 14, and the waste rises with the upper die cutting knife 11. The guide sleeve 10 will remove the waste. When the cutting edge of the cutter 14 is damaged, the cutter 14 is taken out and the grinding wheel surface at the cutting edge is lowered by the thickness of a cutter gasket 15. One of the cutter gaskets 15 between the cutter guide female die 13 and the cutter 14 is taken out and padded at the bottom of the cutter 14 to ensure its height. This cycle continues every time the cutting edge is damaged, reducing costs and enabling multiple uses. For similar molds, this structure is relatively simple. After the cutting edge of the cutter 14 is damaged, the entire cutter female die cannot be used and needs to be reordered, which is laborious and time-consuming. When the electric push rod 16 drives the connecting block 3 to rise, it drives the fixing plate 4 and the fixing block 5 to rise at the same time. When the fixing block 5 drives the mounting plate 6 to rise, it drives the cylinder 7 and the upper die cutting knife fixing rod 8 to rise at the same time. The upper die cutting knife fixing rod 8 drives the upper die cutting knife 11 to rise away from the base 2. The staff can control the distance between the upper die cutting knife 11 and the empty slot 12 according to requirements. The finger enters the cavity opened at the top of the cutter 14, pulls the cutter 14 to drive the cutter 14 and the cutter gasket 15 to rise and pull out of the cutter gasket 15, and performs surface lowering and adjustment of the cutter gasket 15, expanding the operating space and improving convenience.

[0026] When the cutting edge of the cutting knife 14 is damaged, remove the cutting knife 14. Lower the grinding wheel surface at the cutting edge by the thickness of a cutting knife shim 15. Take out one of the cutting knife shims 15 between the cutting knife guiding female die 13 and the cutting knife 14 and place it under the bottom of the cutting knife 14 to ensure its height. Repeat this process each time the cutting edge is damaged. This way, it can be used multiple times, saving resources and reducing costs at the same time.

[0027] While the electric push rod 16 drives the connecting block 3 to rise, it also drives the fixing plate 4 and the fixing block 5 to rise. While the fixing block 5 drives the mounting plate 6 to rise, it also drives the air cylinder 7 and the upper die cutting knife fixing rod 8 to rise. The upper die cutting knife fixing rod 8 drives the upper die cutting knife 11 to rise away from the base 2. Workers can control the distance between the upper die cutting knife 11 and the empty groove 12 according to their needs. Insert a finger into the cavity opened at the top of the cutting knife 14 and pull the cutting knife 14 to drive the cutting knife 14 and the cutting knife shim 15 to rise and be removed from the cutting knife shim 15, so as to lower its surface and adjust the cutting knife shim 15, which expands the operating space and improves convenience.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
