Detailed ways

The technical solution of the present utility model will be further described below in conjunction with Fig. 1 to Fig. 5 and through specific embodiments.

A mold for Z-folding products, comprising an upper mold and a lower mold arranged up and down, the upper mold includes an upper mold base 1 and an upper stripping plate 3 sequentially connected from top to bottom, and the lower mold includes a lower stripping plate connected sequentially from top to bottom Plate 4, lower mold base 7, the inside of the upper stripping plate 3 is provided with a limit entry block 10 that can move up and down, the inside of the upper mold base 1 is provided with an upper mold spring 8, and the bottom of the upper mold spring 8 is in contact with the limit entry block. The top of 10 is provided with the upper ejector pin 9; the inside of the lower stripping plate 4 is provided with a forming punch 12 corresponding to the limit entry block 10 and can move up and down, and the inside of the forming punch 12 is provided with a The lower ejector pin 13, the inside of the lower mold base 7 is provided with a lower die spring 14, and the top of the lower die spring 14 is connected with the bottom of the lower ejector pin 13;

When the Z-fold product is formed, the forming punch 12 pushes the limit entry block 10 to move upward until the bottom surface of the limit entry block 10 and the top surface of the forming punch 12 are located inside the upper stripping plate 3, and the upper die spring 8 is compressed; After the Z-fold product is formed, the forming punch 12 is returned, and the upper die spring 8 pushes the limit entry block 10 to return downward, so as to realize automatic stripping.

The inside of the upper stripping plate 3 is also provided with a crimping block 11, and the crimping block 11 is positioned at one side of the limit entry block 10, and the side of the crimping block 11 is provided with a step, and the limit entry block 10 is close to the step. The side part of the side is provided with a protrusion, and the protrusion extends into the step to realize the limit in the vertical direction, and the vertical dimension of the protrusion is smaller than the vertical dimension of the step.

The elasticity of the lower die spring 14 is greater than that of the upper die spring 8 .

The upper mold also includes an upper backing plate 2, and the upper backing plate 2 is arranged between the upper mold base 1 and the upper stripping plate 3. The lower mold also includes a lower clamping plate 5 and a lower backing plate 6 connected sequentially from top to bottom, and the lower clamping plate 5 And the lower backing plate 6 is located between the lower stripping plate 4 and the lower mold base 7.

The following stripping plate 4, the lower clamping plate 5 and the lower backing plate 6 are provided with guide bolts in the same vertical direction, and the following stripping plate 4 and the lower clamping plate 5 move up and down in the vertical direction of the guiding bolts.

The distance that the lower stripping plate 4 moves downward is 1 mm to 3 mm.

As shown in Figure 1, when the Z-fold product is molded and opened, the sheet to be bent is placed on the lower stripping plate 4 in advance, wherein the first section of the sheet to be bent is placed on the lower stripping plate 4, and the second section of the sheet to be bent is placed on the lower stripping plate 4. The segment is placed on the forming punch 12.

Fig. 2 to Fig. 5 have shown the whole process of forming and stripping of the Z-folding product forming mold of the present invention. When the upper mold and the lower mold are closed, the upper mold moves downward, so that the press-line input block contacts the lower release plate and clamps the first section of the material plate of the product to be formed, and the lower mold spring 14 stretches to push the lower ejector pin 13 Moving upward with the forming punch 12, the forming punch 12 pushes the limit entry block 10 to move upward, so that the forming punch 12 and the limit entry block 10 clamp the second section of the sheet to be bent, and the limit entry block 10 Squeeze the upper ejector pin 9 when moving upwards, the upper ejector pin 9 squeezes the upper die spring 8 and compresses the upper die spring 8, and when the forming punch 12 moves upward beyond the top surface of the lower stripping plate 4, it will naturally form a A Z-fold shape.

As shown in Figure 2, the upper stripping plate 3 descends until it touches the raw material of the product to be formed and crushes the material to death. The forming punch does not touch the raw material of the product to be formed, and the forming has not yet started.

As shown in Figure 3, the upper stripping plate 3 continues to descend until the lower stripping plate 4 moves down by 1.6mm. Since the spring force of the lower die spring 14 is greater than that of the upper die spring 8, the ejector pin 13 of the lower die spring 14 contacts the limit and enters the block 10 and push it to contact with the backing plate 2, and now the position-limiting block 10 cannot go up, and the upper die spring 8 is compressed after being squeezed.

As shown in Figure 4, when the lower plate 4 moves down 3mm, the lower clamping plate 5 contacts the lower backing plate 6, and the entire mold is in a closed mold state. At this time, the lower mold spring 14 is squeezed to the maximum, and the forming punch 12 moves upward beyond the lower plate. The top surface of the stripper 4 completes the Z-folding forming action.

As shown in Figure 5, when the material is removed after bending and forming, the upper mold moves upward, and the lower mold spring 14 shrinks to drive the lower ejector pin 13 and the forming punch 12 to move downward and return to their positions. At the same time, the upper mold spring 8 is The jacking force disappears and rebounds, and drives the upper ejector pin 9 and the limit entry block 10 to return downward, and utilizes the limit entry block 10 to realize automatic material removal.

The crimping block 11 is provided with a groove, and the position-limiting block 10 is provided with a protrusion. The size of the protrusion in the vertical direction is smaller than the size of the protrusion. Not to be ejected.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
