Detailed ways

Referring to Fig. 1 , in conjunction with specific embodiments, the description is as follows: A live core mold according to the utility model includes a male mold 1 and a female mold 5 . The male mold 1 is composed of an outer frame 2 and a live core 3. The inner part of the outer frame 2 is provided with a live core 3, and the two are closely fitted. The live core 3 is provided with a protruding mold Pattern 4, the highest point on the surface of the mold pattern 4 is not higher than the blank holder level of the outer frame 2. The female mold 5 is provided with pattern grooves 6 corresponding to the female and male of the mold pattern 4 , and the overall size of the female mold 5 corresponds to the male mold 1 .

With reference to Fig. 2, in conjunction with specific embodiment, explain as follows: A kind of embossing machine of application live core mold described in the utility model includes base 7, fixed plate 8, lower mold frame 10, upper mold frame 16 and two hydraulic cylinder. A fixing plate 8 is arranged above the base 7 , and a leg 9 is arranged at the bottom thereof, and an embossing space is formed between the base 7 and the fixing plate 8 . On the base 7 , that is, inside the embossing space, a lower mold frame 10 is arranged, and a male mold 1 is arranged on the lower mold frame 10 .

The male mold 1 is composed of an outer frame 2 and a live core 3. The inner part of the outer frame 2 is provided with a live core 3, and the two are closely fitted. The live core 3 is provided with a protruding mold Pattern 4, the highest point on the surface of the mold pattern 4 is not higher than the blank holder level of the outer frame 2.

The bottom of the base 7 is provided with a hydraulic cylinder A11, and the piston rod of the hydraulic cylinder A11 passes through the base 7 and the lower mold frame 10 and is connected with the core 3 to push the core 3 to move up and down.

Below the fixed plate 8, that is, an upper pressure bearing plate 12 is arranged on the upper part of the embossing space, and an upper mold frame 16 is arranged on the bottom surface of the upper pressure bearing plate 12, and a mold frame 16 is arranged on the bottom surface of the upper pressure bearing plate 12, and a The female mold 5 matched with the male mold 1 is provided with pattern grooves 6 corresponding to the male and female patterns of the mold pattern 4 , and the overall size of the female mold 5 corresponds to the male mold 1 .

The fixing plate 8 is provided with a hydraulic cylinder B13, and the piston rod of the hydraulic cylinder B13 passes through the fixing plate 8 and is connected with the upper bearing plate 12 to push the upper bearing plate 12 to move up and down.

The working principle of an embossing machine using a live core mold described in the utility model: first place the metal plate in the embossing space, that is, put it on the male mold 1 . Then start the hydraulic cylinder B13, and the hydraulic cylinder B13 promotes the female mold 5 to move downward by the upper pressure plate 12 and the upper mold frame 16 during the stretching process. The female mold 5 moves down always until the metal plate on the male mold 1 is compacted. Since the male mold 1 adopts a split-type combined structure, the female mold 5 compacts the metal plate through the outer frame 2 of the male mold 1, that is to say, the mold pattern 4 of the live core 3 is only in contact with the metal plate at this time. Core 3 did not initiate substantial embossing. After the metal plate is compacted, the hydraulic cylinder A11 is automatically turned on. During the stretching process, the hydraulic cylinder A11 will push the live core 3 of the male mold 1 to move upward, and the live core 3 will move up and start the embossing operation until it stops after the embossing is completed. The mold used by the embossing machine is a live core mold. In the above operation process, firstly, the metal plate is pressed and fixed through the cooperation between the female mold 5 and the outer frame 2 of the male mold 1, so as to prevent the metal plate from being embossed later. Wrinkles appear during the process. Then, during specific embossing operations, it is only necessary to push the live core 3 of the male die 1 through the hydraulic cylinder A11. During the entire embossing process, the metal plate will not wrinkle, and the active core structure of the male mold 1 can fully reduce the effective working area of the mold, improve the definition of embossing and reduce the power of supporting equipment. After the embossing of the previous batch of metal plates is completed, if the pattern of the next batch of metal plates needs to be replaced, the workers only need to replace the live core 3 and the female die 5 of the male mold 1, which is convenient and quick, and the labor intensity is low. Improve work efficiency.
