DETAILED DESCRIPTION

[0014] Reference Figure 1 , combined with a specific embodiment, the following is described: A movable core mold described in the present invention includes a male mold 1 and a female mold 5. The male mold 1 is composed of an outer frame 2 and a movable core 3. The movable core 3 is movably arranged inside the outer frame 2, and the two are tightly fitted. The movable core 3 is provided with a protruding mold pattern 4, and the highest point of the surface of the mold pattern 4 is not higher than the horizontal plane of the edge pressing of the outer frame 2. The female mold 5 is provided with a pattern groove 6 corresponding to the positive and negative of the mold pattern 4, and the overall size of the female mold 5 corresponds to that of the male mold 1.

[0015] Reference Figure 2 , combined with a specific embodiment, the following is described: the embossing machine using a movable core mold described in the present invention includes a base 7, a fixed plate 8, a lower mold frame 10, an upper mold frame 16 and two hydraulic cylinders. A fixed plate 8 is arranged above the base 7, and a support leg 9 is arranged at the bottom thereof, and an embossing space is formed between the base 7 and the fixed plate 8. A lower mold frame 10 is arranged on the base 7, that is, inside the embossing space, and a male mold 1 is arranged on the lower mold frame 10.

[0016] The male mold 1 is composed of an outer frame 2 and a movable core 3. The movable core 3 is movably provided inside the outer frame 2 and the two are tightly fitted. A protruding mold pattern 4 is provided on the movable core 3, and the highest point of the surface of the mold pattern 4 is not higher than the edge pressing horizontal plane of the outer frame 2.

[0017] A hydraulic cylinder A11 is disposed below the base 7 , and a piston rod of the hydraulic cylinder A11 passes through the base 7 and the lower mold frame 10 and is connected to the movable core 3 to push the movable core 3 to move up and down.

[0018] Below the fixed plate 8, that is, in the upper part of the embossing space, an upper pressure plate 12 is movably arranged, and an upper mold frame 16 is arranged on the bottom surface of the upper pressure plate 12, and a female mold 5 matching the male mold 1 is arranged through the mold frame, and the female mold 5 is provided with pattern grooves 6 corresponding to the male and female mold patterns 4, and the overall size of the female mold 5 corresponds to the male mold 1.

[0019] The fixed plate 8 is provided with a hydraulic cylinder B13, and the piston rod of the hydraulic cylinder B13 passes through the fixed plate 8 and is connected to the upper pressure plate 12 to push the upper pressure plate 12 to move up and down.

[0020] The working principle of the embossing machine using a movable core mold described in the present invention is as follows: first, a metal plate is placed in the embossing space, that is, placed on the male mold 1. Then the hydraulic cylinder B13 is started, and during the extension process of the hydraulic cylinder B13, the female mold 5 is pushed downward by the upper pressure plate 12 and the upper mold frame 16. The female mold 5 moves downward until the metal plate on the male mold 1 is compacted. Since the male mold 1 adopts a split combination structure, the female mold 5 compacts the metal plate through the outer frame 2 of the male mold 1, that is, at this time, the mold pattern 4 of the movable core 3 is only in contact with the metal plate, and the movable core 3 does not start the actual embossing operation. After compacting the metal plate, the hydraulic cylinder A11 is automatically turned on, and during the extension process of the hydraulic cylinder A11, the movable core 3 of the male mold 1 will be pushed upward, and the movable core 3 moves upward and starts the embossing operation until the embossing is completed and stops. The mold used by the embossing machine is a movable core mold. In the above operation process, the metal plate is first compacted and fixed by the cooperation between the female mold 5 and the outer frame 2 of the male mold 1 to prevent the metal plate from wrinkling in the subsequent embossing process. Then, during the specific embossing operation, it is only necessary to push the active core 3 of the male mold 1 through the hydraulic cylinder A11. The metal plate will not be wrinkled during the entire embossing process, and the active core structure of the male mold 1 can also fully reduce the effective working area of ​​the mold, which can improve the clarity of the embossing and reduce the power of the 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 changed, the worker only needs to replace the active core 3 of the male mold 1 and the female mold 5, which is convenient and fast, with low labor intensity, and greatly improves work efficiency.

[0021] Furthermore, between the base 7 and the fixed plate 8, that is, in the embossing space, a plurality of guide rail support columns 14 are arranged along the periphery thereof, the top ends of the guide rail support columns 14 are connected to the fixed plate 8, and the bottom ends thereof are connected to the base 7. The side edges of the upper pressure plate 12 are movably arranged on the guide rail support columns 14, so as to ensure the direction thereof when moving up and down.

[0022] Furthermore, guide rods 15 connected to the lower mold frame 10 are respectively provided on both sides of the upper mold frame 16. The upper mold frame 16 is arranged on the guide rods 15 to further ensure the direction of the upper mold frame 16 when it moves up and down.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
