[0012] The present invention also provides a forging method for a forging die for producing electric power hardware components, the method comprising the following steps: S1. In the initial state, the upper die core is separated from the lower die core, and the material receiving plate is located between the upper die core and the lower die body. When in use, the raw material is placed in the lower die core, and the telescopic cylinder is activated to drive the connecting block and the upper die body downward, so that the upper die core is inserted into the lower die core to forge the raw material; S2. When the upper mold body moves downward, the first and second connecting rods on one side of the upper mold body cooperate with the third and fourth connecting rods to drive the receiving plate to move away from under the upper mold core. At the same time, the connecting rod slides in the sliding groove under the action of the first and fourth connecting rods, pushing the piston rod so that the mold release agent in the piston cylinder is injected into the connecting rod and sprayed onto the upper mold core through multiple spray pipes on the connecting rod; S3. After the product is formed, the electric push rod is started to drive the cutting knife to move downward along the upper mold core to cut the overflowed waste.

When the waste on the cutting knife contacts the upper mold body, it is pushed by the upper mold body and falls off the cutting knife and falls on the receiving plate. It is then transported to the receiving box for centralized collection through the receiving plate; S5. When the connecting block and the upper mold body move upward, they also drive the sliding rod upward, causing the synchronous rack to move upward. The upward movement of the synchronous rack also drives the synchronous gear to rotate. The synchronous gear drives the rotating disk to rotate through the synchronous rod. When the rotating disk rotates, the synchronous connecting rod pulls the sliding block up and down. When the sliding block slides upward, the ejector rod extends from the top of the lower mold core to push out the product in the lower mold core. When the sliding block slides downward, the ejector rod retracts into the lower mold core. After the ejector rod pushes out the product, the worker can take the product out. S6. When the ejector body moves up to the connecting hole and matches the second delivery pipe, the release agent in the second delivery pipe enters the ejector body through the connecting hole and is sprayed into the lower mold core through multiple discharge ports.

[0013] Compared with the prior art, the above solution has the following beneficial effects: 1. The present invention provides a receiving assembly, and during the forging process, the first connecting rod, the second connecting rod, the third connecting rod and the fourth connecting rod cooperate ingeniously to realize the automatic movement and resetting of the receiving plate, thereby ensuring the stability and accuracy of the receiving plate during the forging process. At the same time, the sliding of the connecting rod in the sliding groove can simultaneously drive the injection and spraying of the release agent in the piston cylinder, further improving the degree of automation and production efficiency of the mold. At the same time, the spraying of the release agent not only helps to smoothly demold the product, but also reduces the wear and damage of the mold, thereby extending the service life of the mold.

[0014] 2. The present invention is also equipped with a cutting knife for cutting and collecting waste materials overflowing during the forging process, thereby improving the molding quality of the product. The cut waste materials are stuck on the outside of the cutting knife. After the upper die assembly and the lower die assembly are separated, when the cutting knife is retracted by the electric push rod, the waste materials can be easily removed from the cutting knife and fall onto the receiving plate under the pushing action of the upper die body. The waste materials are then transported to the receiving box through the receiving plate for centralized collection. The waste materials can be removed and collected through a series of operations, thereby greatly improving work efficiency.

[0015] 3. The present invention adopts a transmission mechanism such as a synchronous rack, a synchronous gear, a synchronous rod and a rotating disk to realize the automatic lifting and lowering of the ejector body and the ejection operation of the product. This design improves the efficiency and accuracy of product removal. During the lifting process of the ejector body, the automatic injection and spraying of the release agent are realized through the interaction between the connecting hole and the second conveying pipe. This function not only helps to smoothly demold and remove the product, but also further improves the degree of automation and production efficiency of the mold. BRIEF DESCRIPTION OF THE DRAWINGS

In the initial state, the upper die core (33) is separated from the lower die core (22), and the receiving plate (43) is located between the upper die core (33) and the lower die body (21). When in use, the raw material is placed in the lower die core (22), and the telescopic cylinder (11) is started to drive the connecting block (31) and the upper die body (32) to move downward, so that the upper die core (33) is inserted into the lower die core (22) to forge the raw material; S2. When the upper mold body (32) moves downward, the first connecting rod (41) and the second connecting rod (42) on one side of the upper mold body (32) cooperate with the third connecting rod (44) and the fourth connecting rod (45) to drive the receiving plate (43) to move away from the bottom of the upper mold core (33). At the same time, the connecting rod (47) slides in the sliding groove (46) under the action of the first connecting rod (41) and the fourth connecting rod (45), and pushes the piston rod so that the release agent in the piston cylinder (63) is injected into the connecting rod (47) and sprayed on the upper mold core (33) through the multiple spraying pipes (48) on the connecting rod (47); S3. After the product is formed, the electric push rod (35) is started so that the electric push rod (35) drives the cutting knife (36) to move downward along the upper mold core (33) to cut the overflowed waste material. The overflowed material after cutting is stuck on the outside of the cutting knife (36). After the cutting is completed, the telescopic cylinder (11) is started so that the telescopic cylinder (11) drives the connecting block (31) and the upper mold body (32) to move upward, so that the upper mold assembly (3) is separated from the lower mold assembly (2); S4, when the connecting block (31) and the upper mold body (32) move upward, the first connecting rod (41) and the second connecting rod (42) cooperate with the third connecting rod (44) and the fourth connecting rod (45) to drive the receiving plate (43) to move to the bottom of the upper mold core (33), and the electric push rod (35) is started to retract the cutting knife (36). When the waste on the cutting knife (36) contacts the upper mold body (32), it is pushed by the upper mold body (32) and falls off the cutting knife (36) and falls on the receiving plate (43), and is transported to the receiving box (7) through the receiving plate (43) for centralized collection; S5. When the connecting block (31) and the upper mold body (32) move upward, the sliding rod (24) is driven upward at the same time, so that the synchronous rack (26) moves upward. The synchronous rack (26) moves upward and drives the synchronous gear (27) to rotate. The synchronous gear (27) drives the rotating disk (51) to rotate through the synchronous rod (28). When the rotating disk (51) rotates, the synchronous connecting rod (52) pulls the sliding block (53) to slide up and down. When the sliding block (53) slides upward, the ejector rod body (54) extends from the top of the lower mold core (22) to push out the product in the lower mold core (22). When the sliding block (53) slides downward, the ejector rod body (54) retracts into the lower mold core (22). After the ejector rod body (54) pushes out the product, the worker can take the product out. S6. When the ejector body (54) moves upward to the connecting hole (55) and matches the second delivery tube (64), the release agent in the second delivery tube (64) enters the ejector body (54) through the connecting hole (55) and is sprayed into the lower mold core (22) through the multiple discharge ports (56).
