Among them, the top end of the upper driving block 30 is rhombic, and a forming hole matching the top end of the upper driving block 30 is formed in the middle of the upper forming block 32, enabling the top end of the upper driving block 30 to pass through the first through hole and enter the forming hole of the upper forming block 3. The third side slider 31 is in clearance fit with the second slider guide plate 12 to ensure smooth sliding on the second slider guide plate 12. The contact surface between the upper driving block 30 and the third side slider 31 forms an angle of 15° with the Z-axis. The third side slider 31 is fixedly connected to the upper forming block 3 by bolts.

[0028] Furthermore, a guide rail for the third side slider 31 to slide is provided on the second slider guide plate 12.

[0029] Four first side slider guide plates 8, two wedge stop blocks 7 and a third slider guide plate 27 are arranged on the lower die base 4. The bottom ends of the two wedge stop blocks 7 are slidably installed with the top ends of third fixed-distance screws 22.

A first side slider 9 is fixedly installed on the slider base 28. A height stop block 19 and a second slider pressure plate 20 are successively arranged from top to bottom at the top end of one of the first side slider guide plates 8. Among them, the slider base 28 and the first side slider 9 are fixedly installed on the lower die base 4 by bolts at one time. The second slider pressure plate 20 and the height stop block 19 are fixedly installed on the first side slider guide plate 8 by bolts. A lower driving block 23 is fixedly installed at the middle position of the lower fixing plate 3. A third through hole is arranged at the middle position of the third slider guide plate 27. The top end of the lower driving block 23 is rhombic. A forming hole matching the top end of the lower driving block 23 is formed in the middle of the lower forming block 24, so that the top end of the lower driving block 23 can pass through the third through hole and enter the forming hole of the lower forming block 24. The contact surface between the lower driving block 23 and the second side slider 25 forms an angle of 15° with the Z axis.

[0032] During the mold clamping operation, the upper table surface 15 of the machine tool drives the upper mold base 14 to move downward, and drives the wedge 10 and the height stop column 18 on the upper fixing plate 13 to move downward. After moving a certain distance, the wedge 10 contacts the wedge block 7 and the slider seat 28 respectively. The wedge block 7 is used to offset the lateral force generated during the forming process and provide a thrust for the slider seat 28 to slide toward the middle, so that the slider seat 28 drives the first side slider 9 to slide horizontally toward the middle along the guide rail on the first side slider guide plate 8, and the first return spring 6 on the first fixed-distance screw 5 is gradually compressed; after the upper table surface 15 of the machine tool drives the upper mold base 14 to continue moving downward for a certain distance, the first slider pressing plate 11 contacts the height stop block 19, and the blank holding spring 17 is gradually compressed under the upward pressure. The second side slider guide plate 12 no longer moves relative to the lower film assembly. When the upper table surface 15 of the machine tool drives the upper mold base 14 to continue moving downward, the top end of the upper driving block 30 passes through the first through hole and enters the forming hole of the upper forming block 3. The upper driving block 30 contacts the third side slider 31, and the third return spring is gradually compressed under the action of the upper driving block 30. The third side slider 31 slides horizontally along the guide rail on the second side slider guide plate 12 until the second side slider guide plate 12 contacts the upper fixing plate 13; during the downward movement of the upper mold base 14, the lower mold base 4 moves downward under the action of the height stop column 18, and the unloading spring 21 is gradually compressed under the downward pressure until the lower mold base 4 contacts the lower fixing plate 3; during the downward movement of the lower mold base 4, the lower driving block 23 passes through the third through hole and enters the forming hole of the lower forming block 24. The lower driving block 23 contacts the second side slider 25, and the second return spring 29 is gradually compressed under the action of the lower driving block 23. The second side slider 25 slides horizontally along the guide rail on the third side slider guide plate 27 until the upper film assembly and the lower film assembly are completely clamped, and the side slider flaring forming in the stamping die is completed.

[0033] During the mold opening operation, after the upper table surface 15 of the machine tool drives the upper die holder 14 to move upward a certain distance, under the action of the disengaging stop pillar 18, the unloading spring 21 gradually resets, thereby driving the lower die holder 4 to move upward to the original position; meanwhile, the lower driving block 23 disengages from the second side slider 25, the second return spring 29 gradually resets, and the second side slider 25 slides horizontally along the guide rail on the third slider guide plate 27 to the original position; after the upper table surface 15 of the machine tool drives the upper die holder 14 to continue moving upward a certain distance, the first slider pressing plate 11 disengages from the stop height block 19, the blank holding spring 17 gradually resets, the second slider guide plate 12 moves downward until the top of the second fixed distance screw 16 contacts the upper fixing plate 13, the upper driving block 30 disengages from the third side slider 31, the third return spring gradually resets, and the third side slider 31 slides horizontally along the guide rail on the second slider guide plate 12 to the original position; the angle wedge 10 disengages from the angle wedge stop block 7 and the slider seat 28 respectively, and the first return spring 6 on the first fixed distance screw 5 gradually resets, so that the first fixed distance screw 5 drives the slider seat 28 to slide horizontally outward along the guide rail on the first side slider guide plate 8 to the original position, and the mold opening operation is completed.

[0034] For ease of explanation, spatially relative terms such as "upper", "lower", "left", "right", etc. are used in the embodiments to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations during the use or operation of the device. For example, if the device in the figure is inverted, the element described as being "below" other elements or features will be positioned "above" the other elements or features. Therefore, the exemplary term "lower" can include both the upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0035] Moreover, relative relationship terms such as "first" and "second" are only used to distinguish one component with the same name from another, and do not necessarily require or imply any such actual relationship or order between these components.

[0036] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
