Description

Technical Field

[0001] The utility model relates to the technical field of forging dies, in particular to a die steel bar forging die. Background Art

[0002] Forging dies are important tools used in the forging process. They can be divided into hot forging dies, warm forging dies and cold forging dies according to the forging temperature. Hot forging dies can be further classified according to the different equipment. In press die forging, it is necessary to design and process the die frame and use different types of dies and devices such as blanking dies, trimming dies, punching dies, correction dies, cold precision dies, etc.

[0003] The Chinese patent with the publication number CN211990769U discloses a die steel bar forging die, which includes a die A and a die B. A semicircular groove A is arranged in the middle of one side of the outer surface of the die A, and rectangular clips are arranged on both sides of the semicircular groove A. A semicircular clip is fixedly installed in the middle of a side surface of the die A adjacent to the surface where the semicircular groove A is located. The utility model arranges a semicircular groove A on one side of the die A and a semicircular groove B on one side of the die B. The semicircular groove A and the semicircular groove B form a complete die to forge the die steel bar. The forged die steel bar is demolded by arranging a semicircular demolding hole and a demolding disc, and the operation is simple.

Especially when multiple molds are used at the same time, this manual demoulding method will consume a lot of time and human resources. Therefore, it is necessary to provide a mold steel bar forging mold to solve the above technical problems. Utility Model Content

[0038] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to a power source and a control switch when in use. The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. When in use, the device is installed at a specified position through the mounting frame 2, and a certain number of mold assemblies 3 are installed on the opposite sides of the first mounting plate 5 and the second mounting plate 10 to form a plurality of cylindrical molds. The position of the mold assembly 3 installed on the side of the first mounting plate 5 is fixed, and for the mold assembly 3 installed on the side of the second mounting plate 10, the second mounting plate 10 can be driven to move laterally by controlling the driving end of the second electric telescopic rod 13, so that the mold assembly 3 located on one side of the second mounting plate 10 overlaps with the mold assembly 3 located on one side of the first mounting plate 5 to form a complete mold, and at the same time, the motor 17 is controlled to start working, and the motor 17 is The driving end drives the worm 18 to rotate, and the worm wheel 19 drives the threaded rod 9 to rotate through the meshing of the worm 18 and the worm wheel 19. The threaded transmission between the threaded rod 9 and the top plate 7, and the sliding relationship between the top plate 7 and the limit rod 6, make the top plate 7 stably move vertically, and the movement of the top plate 7 drives the circular sealing plate 15 to move through the top rod 8, so that the circular sealing plate 15 moves upward from the bottom opening of the mold to slide into the bottom of the mold. The movement of the top plate 7 can drive multiple circular sealing plates 15 to enter the corresponding mold at the same time. Subsequently, the forged steel is placed in the complete mold composed of two mold assemblies 3. The steel is forged into a mold steel rod through the extrusion of the mold assembly 3 located on the side of the second mounting plate 10. Then, the circular sealing plate 15 is controlled to move upward inside the mold through the drive of the motor 17, so that the steel rod is ejected from the top opening of the mold. This automated demoulding mechanism eliminates the need for manual operation and solves the problem of large time and human resource consumption when multiple molds are used at the same time.

[0039] When installing the mold assembly 3, the mounting block 20 on the outer surface of the mold assembly 3 is directly inserted into the inside of the mounting groove 22. After a certain number of mold assemblies 3 are installed, the driving end of the first electric telescopic rod 4 is directly controlled to drive the pressing plate 12 to move vertically. The movement of the pressing plate 12 drives the positioning rod 23 to slide on the positioning hole 24, so that the positioning rod 23 moves toward the inside of the mounting groove 22. The positioning rod 23 is directly inserted into the inside of the positioning groove 25 at the top of the mounting block 20 to complete the fixation of the mounting block 20 in the mounting groove 22, ensuring the stability of the mold assembly 3 after installation and use. The installation structure of the mold assembly 3 is simple and easy to operate, which is convenient for users to quickly assemble and disassemble the mold assembly 3, and convenient for users to freely combine and use single molds or multiple molds.
