The adjusting screw 12 is rotatably mounted in the limiting groove 9 via a rolling bearing. The lifting motor 11 is located at the top of the support plate.

[0042] The lifting frame 2 is also provided with a limiting block 10. The limiting block 10 is a square block. The limiting block 10 is inserted into the limiting groove 9. At the same time, the side of the limiting block 10 is in contact with the inner wall of the limiting groove 9, thereby realizing the rotational limitation of the lifting frame 2.

[0043] Meanwhile, a fixing hole 13 is provided at one end of the limiting block 10 that is inserted into the limiting groove 9. The fixing hole 13 is a regular hexagonal structure. An adjusting nut 14 is provided in the fixing hole 13. The adjusting nut 14 is fixedly connected to the limiting block 10. At the same time, the adjusting nut 14 is also threadedly connected to the adjusting screw 12.

[0044] The above structure enables lifting control of the lifting frame 2, and its structure is simple and the control is stable.

[0045] Furthermore, a plurality of connecting slide rods 3 are provided on the bottom surface of the lifting frame 2. Preferably, each of the connecting slide rods 3 is arranged in a ring structure.

[0046] The molding device further includes an upper molding mold 4, which is cylindrical in shape. The upper molding mold 4 includes a fixing plate 401 and a mold body 402. Flange plates are integrally connected to both the fixing plate 401 and the mold body 402. Several sets of coaxial connecting holes 403 are provided between the two flange plates. The connecting holes 403 are evenly arranged around the axis of the upper molding mold 4. Each connecting slide rod 3 is inserted into the connecting hole 403, thereby realizing the sliding connection between the lifting plate and the upper molding mold 4.

[0047] Each of the connecting slide rods 3 is threaded with a limiting nut 5, and the top surface of each limiting nut 5 is in contact with the bottom surface of the upper forming mold 4;

[0048] A plurality of connecting screw holes 405 are provided between the fixing plate 401 and the mold body 402, and a connecting screw 406 is provided in each of the connecting screw holes 405;

[0049] The mold body 402 is provided with a mounting hole 404, and a permanent magnet 6 connected to the fixing plate 401 is placed in the mounting hole 404; at the same time, the permanent magnet 6 is fixedly connected to the fixing plate 401.

[0053] By rotating the adjusting rod 17, the adjusting cable 19 can be pulled, and the upper forming mold 4 can be raised or lowered by the adjusting cable 19, thereby adjusting its height position; and during the adjustment process, it can effectively ensure that the upper forming mold 4 is always in a horizontal state, avoiding the need for posture adjustment later, which is conducive to improving the machine adjustment efficiency.

[0054] Meanwhile, the setting of the adjusting ring 21 and the two pull rings 22 can prevent the adjusting cable 19 from getting tangled during the rotation of the adjusting rod 17, and can also effectively improve the uniformity of the force on the upper forming mold 4.

[0055] Furthermore, at least two of the slide rods 3 are provided with scales 25 on their outer peripheral surfaces;

[0056] The setting of scale 25 can help the staff to detect the height position of the upper forming mold 4, so that the adjustment can be stopped when the specified height is reached, which helps to improve the adjustment efficiency.

[0057] In use, the parts to be processed are placed on the processing station of the lower forming mold. Then, the lifting frame is controlled to move down by the drive device. During the downward movement, the upper forming mold will gradually fit into the lower forming mold. Then, the upper forming mold is pulled to the side of the lower forming mold by the cooperation of the electromagnetic module and the permanent magnet. The processing is achieved by the mutual extrusion of the upper forming mold and the lower forming mold. At the end point of processing, the upper forming mold is tightly fitted with the limiting nut. At this time, the parts to be processed reach the specified thickness.

[0058] When it is necessary to process workpieces of different thicknesses, the upper forming mold is controlled to slide along the slide bar by manual sliding. After reaching the designated position, the position of the limiting nut is adjusted until the limiting nut is in contact with the upper forming mold, thereby changing the downward sliding endpoint of the upper forming mold and meeting the processing requirements of parts of different thicknesses.

[0059] Compared with the prior art, this application can adjust the position of the upper forming mold according to actual needs, thereby meeting the processing requirements of different thicknesses and realizing the diversification of part processing.

[0060] Secondly, the entire set of equipment has a simple and convenient adjustment method, which effectively improves the reliability and stability of the equipment.
