[0022] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples.

[0023] As attached Figure 1 To the attached Figure 7 As shown:

[0024] Example 1: The utility model provides a forging die with a nested double-layer structure, including a die assembly 1 and a lifting assembly 2; the die assembly 1 includes a forging upper die 101, a shaping lower die 102, a nested bottom die 103 and a release block 104, the forging upper die 101 is inserted into the top of the shaping lower die 102, and the top of the forging upper die 101 is connected to the lifting device, the nested bottom die 103 is inserted into the inside of the shaping lower die 102, and the release block 104 is fixedly installed inside the shaping lower die 102; the lifting assembly 2 includes a lifting rod 201 and a synchronization block 202, the lifting rod 201 is fixedly installed at the bottom of the forging upper die 101, and the synchronization block 202 is inserted into the bottom of the lifting rod 201.

[0025] In the embodiment of the present disclosure, a control rod is provided on the side of the nested bottom die 103, and the control rod is inserted into the interior of the shaping lower die 102, a track groove 1032 is provided inside the control rod, and the lifting rod 201 is inserted into the interior of the track groove 1032. In use, when the forging upper die 101 moves down to hammer forge the forging, the forging upper die 101 is directly inserted into the top of the shaping lower die 102, and the forging operation is performed through the impact block forging at the bottom, and when the forging upper die 101 is inserted into the shaping lower die 102, the lifting rod 201 follows the forging upper die 101 to move down, and can drive the nested bottom die 103 to move down synchronously by means of resisting the forging and compressing the ejector spring 1031, thereby restoring the nested bottom. The position of the die 103 during forging is convenient for shaping the bottom of the forging, and in this process, the synchronization block 202 can be inserted into the synchronization slot 1033, which is convenient for the subsequent demolding and separation operation of the forging and the inner cavity of the shaping lower die 102. The side of the track groove 1032 is provided with a synchronization slot 1033, and the cross-sectional shape of the outer block of the synchronization block 202 is a right triangle, and the hypotenuse of the synchronization block 202 block is set downward. The synchronization block 202 is designed as a right triangle, so that the synchronization block 202 will not get stuck when moving inside the track groove 1032. The synchronization block 202 can automatically avoid the components at the connection under the action of the hypotenuse, which is convenient and flexible to use.

[0026] In the embodiment of the present disclosure, a synchronous top spring 2021 is provided inside the synchronous block 202, and the two ends of the synchronous top spring 2021 are respectively against the inside of the synchronous block 202 and the inside of the lifting rod 201. When the forging upper die 101 and the shaping lower die 102 are in the lowest position of hammering, under the action of the synchronous top spring 2021, the synchronous block 202 is inserted into the inside of the synchronous slot 1033. In use, when the forging upper die 101 moves upward, the lifting rod 201 and the synchronous block 202 can move upward synchronously. Under the action of the synchronous top spring 2021, the synchronous block 202 can drive the nested bottom die 103 to move synchronously with the forging upper die 101 through the synchronous slot 1033, thereby realizing the demoulding and separation operation of the forging and the inner cavity of the shaping lower die 102. A release plate 1041 is provided on the side of the release block 104, and the release plate 1041 is a right-angled trapezoidal design. The beveled edge of the support plate 1041 is set downward, and the release support plate 1041 is located directly above the synchronization slot 1033. When the synchronization block 202 moves to the position of the release support plate 1041, under the resistance of the release support plate 1041, the synchronization block 202 will shrink toward the inside of the lifting rod 201 and compress the synchronization spring 2021, so that the synchronization block 202 will then disengage from the inside of the synchronization slot 1033, and the nested bottom die 103 will not continue to move upward with the forging upper die 101, avoiding the phenomenon of forging falling due to excessive movement, and is stable to use. The bottom of the nested bottom die 103 is provided with an ejection spring 1031, and the two ends of the ejection spring 1031 respectively abut against the inside of the nested bottom die 103 and the inside of the shaping lower die 102. Under the action of the ejection spring 1031, the forging is always in a lifted state, which is convenient for taking and the next hammer forging operation.

[0027] The specific usage and function of this embodiment are as follows:

[0028] In the present invention, after the forging is placed into the die cavity of the shaping lower die 102, the hammer forging operation can be started. When the forging upper die 101 moves down to hammer forge the forging, the forging upper die 101 is directly inserted into the top of the shaping lower die 102, and the forging operation is performed through the impact block forging at the bottom. When the forging upper die 101 is inserted into the shaping lower die 102, the lifting rod 201 moves down with the forging upper die 101 and can drive the nested bottom die 103 to move down synchronously by contacting the forging. The ejector spring 1031 is moved and compressed to restore the nested bottom die 103 to its position during forging, thereby shaping the bottom of the forging and completing a single hammering action. During this process, the synchronous card block 202 can be inserted into the synchronous card slot 1033, which also facilitates the subsequent demoulding and separation operation of the forging and the inner cavity of the shaping lower die 102. The synchronous card block 202 is designed as a right-angled triangle, so that the synchronous card block 202 will not get stuck when moving inside the track slot 1032. The synchronous card block 202 Under the action of the bevel, it can automatically avoid the parts at the connection. When the forging upper die 101 moves upward, the lifting rod 201 and the synchronous clamping block 202 can move upward synchronously. Under the action of the synchronous top spring 2021, the synchronous clamping block 202 can drive the nested bottom die 103 to move synchronously with the forging upper die 101 through the synchronous clamping groove 1033, thereby realizing the demoulding and separation operation of the forging and the inner cavity of the shaping lower die 102, and when the synchronous clamping block 202 moves to the position of releasing the plate 1041, the locking plate 1041 is released. Under the resistance of the support plate 1041, the synchronous block 202 will shrink toward the inside of the lifting rod 201 and compress the synchronous top spring 2021, so that the synchronous block 202 will then disengage from the inside of the synchronous slot 1033, and the nested bottom die 103 will not continue to move upward with the forging upper die 101, avoiding the forging falling due to excessive movement. It is stable to use, and under the action of the ejection spring 1031, the forging is always in a lifted state, which is convenient for taking and the next hammer forging operation.
