[0038] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part rather than all of the embodiments of the present utility model.

[0039] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without any creative effort fall within the scope of protection of the present utility model.

[0040] Embodiment 1:

[0041] Please refer to Figures 1 - 4 , a stamping die for the flatness of a product whole plane, including an upper die base 100 and a lower die base 200 located below the upper die base 100. The upper die base 100 is used to connect with an external driving force. Under the action of the external driving force, the upper die base 100 and the lower die base 200 are in a closed or open state.

[0042] An upper leveling block 300 is installed on the lower surface of the upper die base 100, a lower leveling block 400 is installed on the upper surface of the lower die base 200, and a leveling positioning movable block 500 matching the product structure is arranged at the upper end of the lower leveling block 400. The leveling positioning movable block 500 is movably connected to the upper end of the lower leveling block 400 through a first jacking elastic member 600.

[0043] Place the product to be stamped and leveled on the leveling positioning movable block 500. Drive the upper die base 100 to drive the upper leveling block 300 to move downward through an external driving force. The lower leveling block 400 is subjected to the downward acting force of the upper leveling block 300 and squeezes the first jacking elastic member 600 downward until the upper leveling block 300 moves downward in place, so that the whole stamping die is in a closed state to perform stamping and leveling operations on the product. Among them, the upper leveling block 300 can level the upper surface of the product, and the lower leveling block 400 can level the lower surface of the product. After the leveling operation is completed, the upper die base 100 moves upward under the action of the external driving force. After the lower leveling block 400 loses the downward acting force of the upper leveling block 300, it drives the product to jack up under the action of the first jacking elastic member 600, which is convenient for stripping the product and positioning before stamping and leveling the next product.

[0044] It should be noted that the leveling and positioning movable block 500 is matched with the product structure so as to accurately position the product. Refer to Figure 3 , in one example, the product 101 includes a first substrate 101a and a second substrate 101b which are oppositely arranged, and a connecting plate 101c connected between the first substrate 101a and the second substrate 101b, presenting an approximately C-shaped structure as a whole. The product can be sleeved on the leveling and positioning movable block 500 to play a leveling and positioning role through the leveling and positioning movable block 500. Specifically, before the leveling operation, under the action of the first lifting elastic member 600, there is a gap between the leveling and positioning movable block 500 and the lower leveling block 400. When the product is sleeved on the leveling and positioning movable block 500, it is equivalent that the first substrate 101a is located at the upper end of the leveling and positioning movable block 500, the second substrate 101b is located at the lower end of the leveling and positioning movable block 500, and the connecting plate 101c is located at the side of the leveling and positioning movable block 500.

[0045] The lower end of the upper leveling block 300 protrudes downward with an upper protection block 310, and the upper end of the lower leveling block 400 protrudes upward with a lower protection block 410. The upper protection block 310 and the lower protection block 410 are used to make the product abut against the leveling and positioning movable block 500.

[0046] As can be seen from the foregoing, the first substrate 101a is located at the upper end of the leveling and positioning movable block 500, the second substrate 101b is located at the lower end of the leveling and positioning movable block 500, and the connecting plate 101c is located at the side of the leveling and positioning movable block 500. When an external driving force drives the upper die base 100 to drive the upper leveling block 300 to move downward, the lower leveling block 400 is subjected to the downward moving force of the upper leveling block 300 and presses the first lifting elastic member 600 downward until the upper leveling block 300 moves downward in place, making the entire stamping die in a closed state. At this time, through the combined action of the upper leveling block 300 and the upper end of the leveling and positioning movable block 500, the first substrate 101a is leveled, and through the combined action of the lower leveling block 400 and the lower end of the leveling and positioning movable block 500, the second substrate 101b is leveled.

[0047] During this leveling process, the connecting plate 101c may be deformed due to expansion. Therefore, in this embodiment, the upper protection block 310 and the lower protection block 410 are used to ensure that the connecting plate 101c of the product abuts against the side of the leveling and positioning movable block 500, that is, one side of the connecting plate 101c is the upper protection block 310 and the lower protection block 410, and the other side of the connecting plate 101c is the side of the leveling and positioning movable block 500, so as to ensure the stability of the leveling operation.

[0048] Refer to Figure 4, in some embodiments, the leveling and positioning movable block 500 includes an upper leveling plane 510 and a lower leveling plane 520. Avoidance grooves 530 for avoiding the protruding structures on the product are formed on both the upper leveling plane 510 and the lower leveling plane 520, ensuring the leveling effect of the product's flatness.

[0049] There are protruding structures on both the lower surface of the first substrate 101a and the upper surface of the second substrate 101b. Therefore, in order to avoid the protruding structures affecting the leveling operation, an avoidance groove 530 is formed on the upper leveling plane 510 of the leveling and positioning movable block 500 at the position corresponding to the protruding structure on the first substrate 101a, and an avoidance groove 530 is also formed on the lower leveling plane 520 of the leveling and positioning movable block 500 at the position corresponding to the protruding structure on the second substrate 101b. For the shape and quantity of the avoidance grooves 530, they can be adjusted according to the shape and quantity of the protruding structures on the first substrate 101a and the second substrate 101b respectively.

[0050] Furthermore, the leveling and positioning movable block 500 further includes a first side surface 540 connecting the upper leveling plane 510 and the lower leveling plane 520. The first side surface 540 is opposite to the upper protection block 310 and the lower protection block 410, and plays a limiting role in the vertical direction on the product through the first side surface 540, preventing the product from expanding and deforming, and ensuring the stability of the leveling operation.

[0051] In some embodiments, a first rounded corner structure 311 is formed at the end corner of the upper protection block 310 in contact with the product; a second rounded corner structure 411 is formed at the end corner of the lower protection block 410 in contact with the product. The first rounded corner structure 311 and the second rounded corner structure 411 can ensure the smoothness when contacting the product, avoid the product surface generating burrs due to the sharp corner structure, and ensure the quality of the leveling operation.

[0052] Furthermore, the upper leveling block 300 and the upper protection block 310 are of an integrated structure, and the lower leveling block 400 and the lower protection block 410 are of an integrated structure, which is convenient for the installation of the overall mold and improves the stability of use.

[0053] Adopting the upper leveling block 300 and the upper protection block 310 as an integrated structure, when installing the mold, only need to connect and install the upper leveling block 300 with the upper mold base 100. Similarly, adopting the lower leveling block 400 and the lower protection block 410 as an integrated structure, when installing the mold, only need to connect and install the lower leveling block 400 with the lower mold base 200. This saves the installation steps and the alignment and debugging links for the upper protection block 310 and the lower protection block 410, effectively improving the installation efficiency.

[0054] In some embodiments, one end of the first lifting elastic member 600 passes through the lower leveling block 400 and is connected to the inside of the lower die base 200, and the other end of the first lifting elastic member 600 is connected to the lower end of the leveling and positioning movable block 500, ensuring the installation stability of the first lifting elastic member 600 and the use stability of the overall die.

[0055] Connecting one end of the first lifting elastic member 600 through the lower leveling block 400 to the inside of the lower die base 200 can improve the installation stability of the first lifting elastic member 600 and ensure the stability of the elastic force action of the first lifting elastic member 600. In this example, the first lifting elastic member 600 is a spring.

[0056] Example 2:

[0057] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the stamping die of the present utility model. Please refer to Figure 5 .

[0058] The stamping die provided in this embodiment further includes an equal-height sleeve 700 for restricting the moving height of the leveling and positioning movable block 500. One end of the equal-height sleeve 700 passes through the lower leveling block 400 and is connected to the inside of the lower die base 200, and the other end of the equal-height sleeve 700 is connected to the lower end of the leveling and positioning movable block 500. By restricting the moving height of the leveling and positioning movable block 500 through the equal-height sleeve 700, it is convenient for product positioning and flatness debugging.

[0059] Under the action of the equal-height sleeve 700, it can be ensured that the moving height of the leveling and positioning movable block 500 when it is jacked up under the elastic force of the first lifting elastic member 600 remains consistent, so as to facilitate product positioning. At the same time, the equal-height sleeve 700 also facilitates the height debugging of the flatness of the leveling and positioning movable block 500.

[0060] In some embodiments, the stamping die further includes a limit block 800 for restricting the closed height of the die. The limit block 800 is installed on the upper surface of the lower leveling block 400. By means of the limit block 800, it can be prevented that excessive die closing affects the shape and flatness of the product.

[0061] Example 3:

[0062] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the stamping die of the present utility model. Please refer to Figure 6 .

[0063] In this embodiment, a guiding assembly 900 for guiding the die closing is arranged between the upper die base 100 and the lower die base 200. Through the guiding assembly 900, the alignment stability during the die closing process can be ensured, thereby improving the stability of the leveling operation.

[0064] Further, the guiding component 900 includes guiding columns 910 disposed on the lower die base 200 and guiding grooves (not shown in the figure) formed on the upper die base 100. The guiding columns 910 are matched with the guiding grooves to achieve the alignment stability during the die closing process.

[0065] Specifically, during the die closing process, the guiding columns 910 penetrate into the guiding grooves to ensure the stability of the downward movement of the lower die base 200, and further ensure the stability of the leveling operation.

[0066] A stamping die for product flatness provided by the present utility model positions the product before stamping and leveling by setting a leveling positioning movable block to ensure the flatness of the product. At the same time, through the upper protection block and the lower protection block, the product maintains an abutting relationship with the leveling positioning movable block during the stamping and leveling process, preventing the product from expanding and deforming, so as to improve the stability of the leveling operation.
