[0023] Reference Figure 1 This application provides a forging die for a die-cast aluminum cap 110. The die for a die 110 has a first folded edge 111 and a second folded edge 112 on its edge. The die forging die includes a concave die 200, a core die 300, and a punch die 400. The concave die 200 has a cavity, which includes a mounting cavity. The core die 300 is disposed in the mounting cavity and extends into the cavity. A raised ring 310 is provided at the bottom of the core die 300. A sliding groove 210 is provided on the side wall of the mounting cavity. The raised ring 310 is vertically positioned within the sliding groove 210. A preformed cover 120 is provided on the top of the mold core 300. The preformed cover 120 has a bent portion 121 provided downward along the edge of the mold core 300. The punch 400 is raised and lowered above the die 200. The mold core 300 has an upwardly convex first arc surface, and the punch 400 has an upwardly concave second arc surface. The first arc surface and the second arc surface are matched. The punch 400 descends and cooperates with the die 200 and the mold core 300 to forge the bent portion 121 into a first fold 111 and a second fold 112 to obtain a die-cast aluminum cover 110.

[0024] The forging die described in this application is used to forge the aluminum cap 110, which is a simulated die-cast aluminum cap. Compared with the aluminum cap obtained by die casting in related technologies, the aluminum cap will not have defects such as pores and sand holes. The operation is simple, which greatly improves product quality and production efficiency and reduces production costs.

[0025] It should be noted that the imitation die-cast aluminum cap 110 is made of aluminum alloy Alu3003. Alu3003 material can not only be forged, but also undergo surface hard anodizing treatment, thereby increasing the surface hardness of the imitation die-cast aluminum cap 110 and improving product quality.

[0026] It should also be noted that the stop of the cavity is matched with the outer diameter of the punch 400, so that the cavity can play a certain guiding role for the punch, thus facilitating mold adjustment.

[0027] In this embodiment, a lower base plate 220 is provided at the bottom of the die 200, and an upper base plate 410 is provided at the top of the punch 400. The lower base plate 220 is connected to the die 200 by a first screw, and the upper base plate 410 is connected to the punch 400 by a second screw. The lower base plate 220 and the upper base plate 410 facilitate the installation of the die 200 and the punch 400. The connection via the first and second screws improves the stability of the connection, enhancing the overall stability and reliability. Furthermore, the lower base plate 220 has a first groove 230, which the die 200 engages with. The upper base plate 410 has a second groove 420, which the punch 400 engages with. The first groove 230 and the second groove 420 facilitate rapid positioning between the die 200 and the lower base plate 220, and between the punch 400 and the upper base plate 410, simplifying operation and improving work efficiency.

[0028] Reference Figure 1 In some embodiments of this application, the mounting cavity is disposed through the die 200, and a material ejection mechanism is provided between the lower base plate 220 and the mold core 300. By providing a material ejection mechanism, when the punch 400 rises and moves away from the die 200, the material ejection mechanism drives the product out of the die 200, reducing the difficulty of material removal and improving work efficiency.

[0029] Specifically, the ejection mechanism includes a positioning post 240 and a spring 250. The positioning post 240 slides through the lower base plate 220, and a disc is provided on the top of the positioning post 240. The disc is connected to the mold core 300. The spring 250 is sleeved on the positioning post 240 and located between the lower base plate 220 and the disc. When the punch 400 descends and presses against the mold core 300, the mold core 300 descends, causing the punch 400 to cooperate with the die 200 and the mold core 300 to forge the bent portion 121 into the first folded edge 111 and the second folded edge 112. At this time, the positioning post 240 descends with the mold core 300, and the spring 250 is in a compressed state. After the forging is completed, the punch 400 rises. At this time, the mold core 300 is no longer subjected to the pressure applied by the punch 400. The mold core 300 then drives the imitation die-cast aluminum cover 110 to rise under the action of the spring 250's reset function, thereby realizing the automatic ejection of the imitation die-cast aluminum cover 110. By incorporating spring 250, automatic unloading of the die-cast aluminum cap 110 can be achieved without additional power, saving energy and improving the production environment. The positioning post 240 positions spring 250, enhancing the stability and reliability of the unloading process. Furthermore, the disc spring 250 increases elasticity, preventing mold jamming and further improving stability and reliability.

[0030] It is conceivable that the lower base plate 220 is provided with a third groove 260, the positioning pin 240 is located in the third groove 260, the disc is adapted to the third groove 260, and the two ends of the spring 250 are connected to the bottom of the third groove 260 and the disc, respectively. By providing a third groove 260 in the lower base plate 220, the ejection mechanism can be located within the third groove 260, thus making the structure reasonable and compact, and easy to install. It is easy to understand that the mold core 300 is provided with a fourth groove 320, and the disc is embedded in the fourth groove 320, so as to realize the quick positioning and connection between the mold core 300 and the positioning pin 240, which is simple in structure and easy to operate.

[0031] Reference Figure 1 In some embodiments of this application, a step is provided on the outer side of the die 200, and an explosion-proof ring 270 is fitted onto the step. By tightly clamping the die 200 with the explosion-proof ring 270, the die 200 can be prevented from exploding in all directions after being subjected to excessive forging action by the punch 400, thereby extending the service life of the die 200 and improving its stability and safety.

[0032] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
