Description

Technical Field

[0001] This utility model relates to the technical field of shoe material processing equipment, specifically to a die structure used for shoe material blanking. Background Technology

[0002] When producing shoes, a die is used to cut the various parts of the shoe to cut the shoe material into the required outline. Then, the cut shoe material is marked and sewn.

[0003] During the cutting process, a die is used in conjunction with a stamping machine to cut the shoe material. During each lifting and lowering of the stamping machine, the worker needs to place the die above the shoe material to be cut, and then press down the die to obtain the shoe material with a specific outline.

[0004] The problem with the existing technology is that each time the cutting process is completed, the worker needs to pick up the die, take out the shoe material cut from the die, keep it in his hand, and then place the die in a new position. After repeating this process several times, the worker collects a certain number of cut shoe materials, aligns the outlines of the cut shoe materials in his hand, ties them together, and stores them in an orderly manner for subsequent processing.

[0005] This process requires repeatedly removing the cut shoe material, which is time-consuming. If the die structure is improved so that it can collect a certain amount of cut shoe material without affecting the new cutting, the repeated removal steps can be eliminated, and only one removal is needed, which will greatly improve production efficiency.

[0006] Moreover, the process of aligning and binding the outlines by workers is quite cumbersome. If auxiliary tools could be designed, it would make the operation easier for workers. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this invention provides a die structure for shoe material cutting.

[0008] A further feature of this utility model is a die structure for shoe material cutting. The die includes a frame, a pressure-bearing component, an intercepting component, a first elastic reset component, and a second elastic reset component. The frame includes a pressure-bearing end face, a cutting end face, and a cutting through groove penetrating the pressure-bearing end face and the cutting end face. The cutting through groove has a cutting edge at the edge of the groove opening on the cutting end face. The pressure-bearing end face has a first sliding groove in the same direction as the cutting through groove. The side wall of the cutting through groove has a second sliding groove that communicates with and is perpendicular to the first sliding groove. The second sliding groove is located near the cutting end face.

[0009] The pressure-receiving component includes a pressure-receiving end and a first driving end. The pressure-receiving component is disposed in the first sliding groove for sliding engagement. The first elastic reset component is disposed in the first sliding groove and is linked to the pressure-receiving component to drive the pressure-receiving end out of the first sliding groove.

[0010] The interceptor includes an acute-angle end and a second driving end. The interceptor is disposed in the second sliding groove for sliding engagement. The second driving end is linked with the first driving end. The pressure-bearing member drives the acute-angle end to retract into the cutting through groove. The second elastic reset member is disposed in the second sliding groove and is linked with the interceptor, driving the acute-angle end to protrude into the second sliding groove.

[0011] A further feature of this invention is that the first driving end and the second driving end are respectively provided with a first wedge-shaped surface and a second wedge-shaped surface that are adapted to each other, and the first wedge-shaped surface and the second wedge-shaped surface are in sliding fit.

[0012] Further features of this invention: the first slide groove and the second slide groove are L-shaped, and the two sides of the first slide groove are provided with limiting guide grooves. The pressure-bearing member is provided with a limiting lug corresponding to the position and contour of the limiting guide groove. The first elastic reset member is a spring, which is compressed between the limiting lug and the bottom of the limiting guide groove, and one end of the spring is fixedly connected to the limiting lug.

[0013] The interceptor is T-shaped, and the width of the first groove is adapted to the sliding distance of the second drive end.

[0014] A further feature of this invention is that the acute angle end includes a bottom surface parallel to the cutting end face and a slope surface facing the pressure end face. The second elastic reset member is a spring, which is compressed between the interceptor and the bottom of the second slide groove, driving the acute angle end to slide towards the cutting through groove.

[0015] A further feature of this invention is that the outer peripheral surface of the frame is provided with an annular groove and several rubber bands bound in the annular groove. The annular groove is located near the pressure end face and is provided with an operating groove that extends through to the pressure end face.

[0016] This utility model has the following beneficial effects:

[0017] When the die-cutting mold is placed on the shoe material, it is pressed down by the stamping equipment, which first presses the pressure-receiving part down. Then, the first driving end of the pressure-receiving part slides with the second driving end of the intercepting part in a wedge-shaped surface, thereby driving the acute angle end of the intercepting part to retract into the second groove.

[0018] Then, the stamping equipment continues to descend and press the frame, driving the cutting edge of the frame to cut the shoe material, resulting in a shoe material piece that matches the contour of the cutting groove. At this time, the shoe material piece is in the cutting groove. As the stamping equipment rises, the die loses external force, and the first and second elastic reset springs drive the pressed part to rise and slide to reset, and the acute angle end to slide to reset in the direction of the cutting groove, so that the acute angle end protrudes into the cutting groove, blocking the shoe material piece and preventing it from falling.

[0019] This design eliminates the need for operators to remove shoe material pieces one at a time during each punching operation. Shoe material pieces that are limited and stuck in the cutting groove can move with the die to the next station and repeat the punching action. New shoe material pieces enter the cutting groove and are held in place by the sharp-angled end, forming a stack of shoe material pieces.

[0020] After a certain number of shoe material pieces have been stacked (the depth can be adjusted according to the thickness of the shoe material and the depth of the cutting groove), the operator pours the stacked shoe material pieces out from the pressure end side, while simultaneously using their fingers to pull out the rubber band at the operating groove to bind the stacked shoe materials.

[0021] This die-cutting design optimizes the punching process for shoe materials and assists in pre-stretching the elastic bands, enabling multiple punching and alignment of the pieces, thereby facilitating one-time binding, simplifying worker operations, and significantly improving production efficiency.

The frame 1 includes a pressure-bearing end face 11, a cutting end face 12, and a cutting through groove 13 penetrating the pressure-bearing end face 11 and the cutting end face 12. The cutting through groove 13 has a cutting edge 14 at the edge of the groove opening of the cutting end face 12. The pressure-bearing end face 11 has a first sliding groove 15 in the same direction as the cutting through groove 13. The side wall of the cutting through groove 13 has a second sliding groove 16 that communicates with and is perpendicular to the first sliding groove 15. The second sliding groove 16 is located near the cutting end face 12.

[0033] The pressure-receiving component 2 includes a pressure-receiving end 21 and a first driving end 22. The pressure-receiving component 2 is disposed in the first sliding groove 15 for sliding cooperation. The first elastic reset component 4 is disposed in the first sliding groove 15 and is linked to the pressure-receiving component 2 to drive the pressure-receiving end 21 out of the first sliding groove.

[0034] The interceptor 3 includes an acute-angle end 31 and a second driving end 32. The interceptor 3 is disposed in the second sliding groove 16 for sliding engagement. The second driving end 32 is linked with the first driving end 22. The pressure-bearing member 2 drives the acute-angle end 31 to retract into the cutting through groove 13. The second elastic reset member 5 is disposed in the second sliding groove 16 and is linked with the interceptor 3, driving the acute-angle end 31 to protrude into the second sliding groove 16.

[0035] The first driving end 22 and the second driving end 32 are respectively provided with a first wedge surface and a second wedge surface that are adapted to each other, and the first wedge surface and the second wedge surface are in sliding fit.

[0036] The first slide groove and the second slide groove are L-shaped. The first slide groove is provided with limit guide grooves 17 on both sides. The pressure member 2 is provided with limit lugs 23 in a position and contour matching the limit guide grooves 17. The first elastic reset member 4 is a spring, which is compressed between the limit lugs 23 and the bottom of the limit guide grooves 17, and one end of the spring is fixedly connected to the limit lugs 23.

[0037] The interceptor 3 is T-shaped, and the width of the first groove is adapted to the sliding distance of the second drive end 32.

[0038] The acute angle end 31 includes a bottom surface parallel to the cutting end face 12 and a slope surface facing the pressure end face 11. The second elastic reset member 5 is a spring, which is compressed between the interceptor 3 and the bottom of the second slide groove 16, driving the acute angle end 31 to slide towards the cutting through groove 13.

[0039] The outer circumferential surface of the frame 1 is provided with an annular groove 18 and several rubber bands wrapped in the annular groove 18. The annular groove is located near the pressure end face 11 and is provided with an operating groove 19 that extends through to the pressure end face 11.

[0040] When the die-cutting mold is placed on the shoe material, it is pressed down by the stamping equipment, which first presses down the pressure-receiving part 2. Then, the first driving end 22 of the pressure-receiving part 2 slides with the second driving end 32 of the intercepting part 3 in a wedge-shaped surface, thereby driving the acute angle end 31 of the intercepting part 3 to retract into the second slide groove 16.

The shoe material piece that is stuck in the cutting groove 13 due to the limit can move with the die to the next station and repeat the punching action. The new shoe material piece enters the cutting groove 13 and is held in place by the acute end 31, forming a stack of shoe material pieces.

[0043] After a certain number of shoe material pieces have been stacked (the depth can be adjusted according to the thickness of the shoe material and the depth of the cutting groove 13), the operator pours the stacked shoe material pieces out from the pressure end face 11 side, while simultaneously using their fingers to pull out the rubber band at the operating groove 19 to tie the stacked shoe materials together.

[0044] This die-cutting design optimizes the punching process for shoe materials and assists in pre-stretching the elastic bands, enabling multiple punching and alignment of the pieces, thereby facilitating one-time binding, simplifying worker operations, and significantly improving production efficiency.
