[0002] Stamping dies are key process equipment used in industrial manufacturing for stamping metal sheets. Through the cooperation of upper and lower dies, pressure is applied to the metal sheet under the action of a press, causing it to undergo plastic deformation or separation within the die cavity, thereby forming a part shape that meets the design requirements in one go. They are widely used in manufacturing industries such as automobiles, electronics, aerospace, and home appliances. For example, the authorized patent with announcement number CN203292296U (a stamping die): includes an upper die base and a lower die base. Several sleeves are fixedly arranged on the upper die base. Guide posts that can be inserted into the sleeves are fixedly arranged on the lower die base. Buffer springs are arranged inside the sleeves. A stamping block is arranged on the upper die base. A punch is arranged on the stamping block. The lower end of the punch is electro-sprayed with a wear-resistant layer. While the aforementioned existing technologies can conveniently extend the service life of the punch, they lack a structure for rapid demolding. Consequently, during the use of stamping dies, it is not convenient to quickly demold stamped products, thus affecting stamping production efficiency. Therefore, the market urgently needs to develop a stamping die that facilitates rapid demolding to help people solve the existing problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4 An embodiment of this utility model provides a stamping die for easy and quick demolding, comprising a base plate 1, a lower die 2 fixedly mounted on the top of the base plate 1, an upper die 3 above the lower die 2, and an mounting plate 4 fixedly mounted on the top of the upper die 3. The mounting plate 4 is used for installation and connection with an external lifting drive mechanism to facilitate the lifting and moving of the upper die 3. A stamping cavity 204 is provided on the upper end surface of the lower die 2, and a stamping die head 14 is provided inside the stamping cavity 204. The stamping die head 14 is fixedly connected to the upper die 3. A bottom cavity 203 is provided at the bottom of the lower die 2, and a lifting plate 10 is provided inside the bottom cavity 203. Top rods 11 are symmetrically fixedly mounted on both sides above the lifting plate 10. Top plate grooves are symmetrically provided on both sides below the stamping cavity 204 inside the lower die 2, and a top plate 12 is provided inside the top plate groove. The upper end of the top rod 11 slides into the interior of the top plate groove and is fixedly connected to the top plate 12.

[0018] Inside the lower die, a linkage ejection mechanism consisting of a bottom cavity 203, a lifting plate 10, ejector pins 11, and a top plate 12 is set up. After stamping is completed, the lifting plate 10 drives the ejector pins 11 on both sides to rise synchronously, pushing the top plate 12 to apply force evenly from both sides of the stamping die cavity 204, so that the formed product can quickly leave the die cavity, which significantly improves the production efficiency of continuous stamping operations and increases practicality.

[0019] Please see Figure 1 , Figure 2 and Figure 4The lower mold 2 has symmetrically arranged side openings 202 on both sides, which are connected to the bottom cavity 203. The lifting plate 10 has symmetrically fixed side plates 7 on both sides. One end of the side plate 7 extends to the outside of the lower mold 2 through the side opening 202. A column 8 is fixedly installed on one side above the side plate 7. The two sides below the mounting plate 4 have symmetrically fixed linkage boxes 9. The upper end of the column 8 slides into the interior of the linkage box 9. A linkage plate 15 is fixedly installed on the top of the column 8.

[0020] This structural design establishes an effective linkage mechanism between the lifting plate 10 and the mounting plate 4. During the stamping process, after the upper die 3 rises a certain distance after the stamping is completed, it can drive the lifting plate 10 to rise through the linkage relationship, thereby ejecting the stamped product.

[0021] Please see Figure 4 Rubber rings 16 are fixedly installed on the outer sides above and below the linkage plate 15.

[0022] The rubber ring 16 is designed to cushion the impact between the linkage plate 15 and the linkage box 9, thus increasing its practicality.

[0023] Please see Figure 3 Guide rods 13 are symmetrically arranged on both sides inside the bottom cavity 203. The upper end of the guide rod 13 is fixedly connected to the lower mold 2, and the lower end of the guide rod 13 slides through the lifting plate 10.

[0024] The guide rod 13 provides precise vertical guidance for the lifting plate 10, ensuring that the ejection structure does not shift or jam during movement, thus improving the stability of the demolding action.

[0025] Please see Figure 1 and Figure 2 The lower mold 2 has a lower side groove 201 at each of the four corners on the outside. The upper mold 3 has an upper side groove 301 above the lower side groove 201 on the outside. A guide cylinder 5 is fixedly installed inside the lower side groove 201 of the lower mold 2. A guide post 6 is provided above the guide cylinder 5. The upper end of the guide post 6 extends into the interior of the upper side groove 301 and is fixedly connected to the upper mold 3. The lower end of the guide post 6 slides into the interior of the guide cylinder 5.

[0026] The cooperation between the guide cylinder 5 and the guide post 6 provides precise guidance and positioning for the mold closing and opening movements of the upper mold 3 and the lower mold 2.

[0027] Working principle: During use, in the stamping operation, the upper die 3 drives the stamping die head 14 to move downwards and cooperate with the stamping cavity 204 of the lower die 2 to perform stamping and forming. After stamping, the upper die 3 rises a certain distance. Through the linkage relationship between the linkage box 9 below the mounting plate 4, the column 8 on the side plate 7, and the linkage plate 15, the lifting plate 10 is driven to rise along the bottom cavity 203 under the vertical guidance of the guide rod 13. The push rods 11 on both sides of the lifting plate 10 rise synchronously, pushing the top plate 12 to apply force evenly from both sides of the stamping cavity 204, quickly ejecting the formed product from the cavity and achieving rapid demolding. At the same time, the cooperation of the guide cylinder 5 and the guide column 6 provides precise guidance and positioning for the entire mold closing and opening movement of the upper die 3 and the lower die 2, ensuring stable mold operation and increasing practicality.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
