[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] At present, when processing and polishing the mold, a clamp is usually used to clamp and fix the mold to ensure the stability of the mold during the processing. The mold includes valve body molds, bending pipe molds and other tubular molds and molds with circular parts. During the mold processing, it is difficult to clamp the mold with a tubular shape or a circular part, which can easily cause vibration or displacement between the mold and the clamp during processing, thereby damaging the mold surface.

Therefore, the mold is often manually removed from the clamping tool, and the processing angle is changed and then re-clamped. This operation process not only increases the workload of workers, but also reduces processing efficiency. Utility Model Content

[0028] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0029] Example 1

[0030] In a typical implementation of the present invention, Figure 1 As shown, a mold processing positioning clamping seat is provided, which is mainly used for clamping tubular molds with circular parts such as valve body molds and bending molds, including a clamping table 6, the bottom of the clamping table 6 is vertically connected to the rotating shaft 3, the other end of the rotating shaft 3 away from the clamping table 6 is connected to the shaft sleeve 2, the other end of the shaft sleeve 2 away from the rotating shaft 3 is fixedly connected to the base 1, and the clamping table 6 and the base 1 are parallel to each other.

[0031] By setting the rotating shaft 3 between the base 1 and the clamping table 6, the clamping table 6 can be conveniently adjusted to a certain angle after clamping the mold to be processed, so that the operator can process the mold at multiple angles. At the same time, it can be understood that the clamping table 6 is connected to the base 1 through the rotating shaft 3, and the size of each structure can be set according to actual needs while ensuring the stability of the overall clamping table.

[0032] In other embodiments of the present invention, the base 1 may also be provided with a certain number of fixing structures for fixing the base at a work station to ensure stability during processing, and may also be used in conjunction with other processing machine tools.

[0033] Two grooves of the same size are symmetrically provided on the clamping table 6, and the first screw 5 and the second screw 10 are respectively provided inside the two grooves. The first screw 5 and the second screw 10 are fixedly connected by passing through the grooves, and the thread directions of the first screw 5 and the second screw 10 are opposite. It can be understood that the groove can be set at the top position of the clamping table 6 according to actual conditions, and the first screw 5, the second screw 10 are parallel to the top plane of the clamping table 6.

[0034] The first screw 5 and the second screw 10 are symmetrically connected to two support plates 7 by threads. When the first screw 5 and the second screw 10 rotate at the same time, the two support plates 7 move towards each other and the movement distance is consistent. Such a setting is suitable for clamping tubular, circular and other molds. A clamping plate 8 is respectively provided on the two support plates 7. In this embodiment, the clamping plate 8 is configured as a right-angle clamping plate.

[0039] The splint 8 is connected to the support plate 7 via a connecting shaft 11, and the connecting shaft 11 is vertically rotatably connected to the support plate 7.

[0040] The surface of the clamping plate 8 is provided with a rubber coating, which protects the mold to be processed when clamping, improves the stability of clamping, and avoids changing the angle during clamping to damage the mold surface. In other embodiments of the utility model, other anti-slip and wear-resistant coatings can also be used, and the coating can also be installed only on the contact surface between the clamping plate 8 and the mold to be processed.

[0041] The base 1 is provided with an arc groove 14, the rotating shaft 3 is connected with a connecting rod 17, the end of the connecting rod 17 away from the rotating shaft 3 is connected with a threaded pin 16, the threaded pin 16 is slidably connected to the arc groove 14 of the base 1, the upper part of the end where the threaded pin 16 is connected to the connecting rod 17 is threadedly connected with a nut, and a scale line 15 is provided on the outside of the arc groove 14.

[0042] In this configuration, the shaft 3 is connected to a connecting rod 17, and the connecting rod 17 is connected to a threaded pin 16. The threaded pin 16 can slide in the arc groove 14 on the base 1. When sliding to a specified position, the connecting rod 17 can be locked by tightening the nut, and the connecting rod 17 can be rotated by loosening the nut.
