Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0019] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0020] Example 1, as Figures 1 to 5 As shown, a stamping die for a cup-shaped blank includes a die core 1, a die cavity 2, and a die base 3. The bottom of the die core 1 is provided with a cup-shaped die head 13, used to stamp the raw material into a cup-shaped blank during stamping. The die head 13 is located inside the die cavity 2, which has an internal inclined surface 24 for matching the stamped cup-shaped blank. A ejector plate 4 is movably mounted on the bottom of the die cavity 2, and a top head 43 is provided on the top of the ejector plate 4. The ejector plate 4 ejects the stamped cup-shaped blank through the top head 43.

[0021] The die 2 is fixedly connected to the die base 3, which provides support for the stamping of the cup-shaped blank. During operation, the die base 3 is fixed to the worktable by countersunk screws.

[0022] In implementation, according to the existing stamping device, the top of the die core 1 is provided with an upper fixed column 14 that is movably connected to the external first driving device, and the bottom of the ejector plate 4 is provided with a lower fixed column 42 that is movably connected to the external second driving device. The first driving device and the second driving device can be either a pneumatic cylinder or an electric cylinder, used to generate linear stamping action. The first driving device and the second driving device are controlled by a PLC to control the cycle of their actions.

[0023] As a preferred embodiment, in order to facilitate the stamping of cup-shaped blanks and demolding, the upper fixed post 14 and the lower fixed post 42 are respectively provided with keyways and external threads. These keyways and external threads are used to connect the upper fixed post 14 to the external second driving device and the lower fixed post 42 to the external second driving device, thereby generating a linear driving force to realize the stamping of cup-shaped blanks or the demolding of cup-shaped blanks by ejecting the die 2.

[0024] This invention features a cup-shaped die head 13 at the bottom of the die core 1, used to stamp raw materials into cup-shaped blanks during stamping. This die 2 has an internal inclined surface 24 for matching the stamped cup-shaped blank. A release plate 4, movably mounted at the bottom of the die 2, releases the stamped cup-shaped blank via a top head 43. The entire cup-shaped blank stamping process is simple, and the blank can be demolded after completion. This stamping die reduces the cost of cup-shaped blanks and is suitable for mass production.

[0025] Example 2, based on Example 1, please refer to... Figure 2 and Figure 5 The mold core 1 has a top cover 11 in the middle, and a top plate 12 at the bottom of the top cover 11. The edge of the top cover 11 is flush with the edge of the cavity mold 2, thus serving an aesthetic purpose. When the cavity mold 2 has a cylindrical structure, the top cover 11 also has a cylindrical structure. When the cavity mold 2 has a rectangular shape, the top cover 11 also has a rectangular shape.

[0026] Additionally, the top plate 12 has a disc-shaped structure whose shape matches the top cavity of the die 2. Please refer to [link / reference]. Figure 5 This allows for better interlocking and facilitates the stamping of cup-shaped blanks. The outer periphery of the top plate 12 has a beveled structure, which facilitates matching with the top cavity of the die 2 and also guides the stamping action.

[0027] The bottom of the top plate 12 is fixedly connected to the die head 13. The top plate 12 and the die head 13 are coaxially arranged. The die head 13 itself has a cup-shaped structure, which facilitates the stamping of cup-shaped blanks with the die 2 during stamping. The gap between the inner cavity of the die 2 and the outer wall of the die head 13 is the stamping space for the cup-shaped blank.

[0028] Example 3, based on Example 1, please refer to... Figure 2 and Figure 5 The bottom of the die 2 has a central hole 21, and the bottom of the inner cavity of the die 2 has a relief groove 25. The main body of the ejector plate 4 is installed in the relief groove 25, and the lower fixing column 42 at the bottom of the ejector plate 4 extends through the central hole 21 to the bottom, thereby connecting with the second drive device in the outside to realize linear conveying.

[0029] To facilitate fixed assembly with the mold base 3, a positioning hole 22 and a threaded hole 23 are provided on the bottom outer periphery of the die 2. The die 2 is installed in the positioning hole 22 through the positioning pin 31 and is inserted into the mold base 3 to achieve precise assembly. Then, the die 2 is fixedly connected to the mold base 3 by screws installed in the threaded hole 23, and the mold base 3 is fixed to the stamping worktable by countersunk screws.

[0030] The demolding template 4 includes an anvil 41, which is the main body of the demolding template 4. During operation, the anvil 41 is installed in the clearance groove 25, and the lower fixing post 42 at the bottom of the anvil 41 passes through the central hole 21 and is connected to the external second driving device. The top head 43 is installed on the top of the anvil 41 and is powered by the external second driving device to drive the demolding template 4 to move up and down. After the cup-shaped blank is punched, the demolding template 4 is driven to rise upward by the second driving device, thereby using the top head 43 to lift the punched cup-shaped blank for demolding.

[0031] This stamping die can be applied to technical fields such as machining, aerospace components, and agricultural production as needed. It can replace a large amount of manual labor, control costs and increase efficiency, and has a wide range of applications.
