[0038] Example

[0039] See also Figure 1-2 As shown, this embodiment is a high-efficiency home appliance slide rail stamping die with automatic demoulding function, comprising:

[0040] The upper die base 1 includes an upper die base 2 and a lower plate 8. An upper plate 2 is fixed to one side of the upper die base 1. An upper clamp 3 is fixed to the upper plate 2. A lower die base 9 at the bottom of the upper die base 1 is fixed to the lower plate 8. A cylinder 10 is fixed inside the lower die base 9.

[0041] The upper clamping plate 3 is fixed with a stop plate 4, and the stop plate 4 is fixed with a stripper plate 5. The lower clamping plate 7 is fixed on the lower pad 8, and the lower template 6 above the lower clamping plate 7 is fixedly connected with a first spring 12.

[0042] A die slider 11 is slidably connected to the lower clamping plate 7, and a lower die latch 13 is slidably connected to the lower die plate 6;

[0043] The die slide 11 passes through the lower die plate 6

[0044] The lower mold plate 6 is fixed with equal height screws 14 at both ends, and a second spring 15 is fixed on the equal height screws 14. A punch slider 16 is fixed on the equal height screws 14. A push rod 17 is fixed on both sides of the stripping plate 5.

[0045] Upper die inserts 18 are fixed on both sides of the upper die base 1, a workpiece 19 is placed on the lower die plate 6, and the bottom of the workpiece 19 contacts a lower die float 20;

[0046] The upper die insert 18 passes through the upper pad 2, the upper clamping plate 3, the stop plate 4 and the upper stripper plate 5, and is located outside the ejector rod 17;

[0047] When used specifically:

[0048] The workpiece 19 is placed on the lower mold plate 6, and the punch press provides downward movement power. The upper mold base 1 moves downward, driving the upper stripper plate 5 to move downward. The upper stripper plate 5 presses the workpiece 19 to move downward. The push rod 17 presses the lower mold float 20, pressing the lower mold float 20 back to the lower mold plate 6. The workpiece 19 fits with the lower mold plate 6, and the cylinder 10 is ventilated to drive the lower mold latch 13 to move upward.

[0049] When the lower die plate 6 moves downward, the first spring 12 contracts and opens the die slider 11. The die slider 11 presses against both sides of the workpiece 19 to prevent the workpiece 19 from deforming. The punch press drives the upper die seat 1 to continue to move downward. The upper die insert 18 drives the lower die pin 13 to move horizontally to the middle. The lower die pin 13 cooperates with the die slider 11 to cut into the workpiece 19 and remove the slider stop point.

[0050] The punch press drives the upper die seat 1 to move upward, the cylinder 10 retreats, the first spring 12 pushes the die slider 11 back to the center position, the punch slider 16 retreats to both sides under the action of the second spring 15, and the lower die float 20 moves upward to eject the workpiece 19, and the workpiece 19 is taken out, completing a cycle;

[0051] This arrangement of the device can punch the stop points on both sides of the household appliance slide rail at one time, with high production efficiency and small fluctuation in the size of the stop points, making it convenient for subsequent assembly.
