[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0030] Referring to Figure 1 - Figure 3 , an embodiment provided by the present utility model: A gas meter sealing ring mold includes a base 1. The base 1 plays a role in stable support, improving the stability of the equipment during operation. A pressing mechanism is provided on the top of the base 1. A workbench 8 for riveting the upper and lower watch cases is fixedly connected to the top of the base 1. A positioning mechanism is provided on the top of the workbench 8. The positioning mechanism includes a positioning rod 10 and a lower die 7. A slot 9 is opened on the top of the workbench 8. The positioning rod 10 is fixedly installed at the bottom of the inner wall of the slot 9. The positioning rod 10 plays a positioning role, ensuring that the lower die 7 can be installed directly below the upper die 6 during installation, improving the installation accuracy of the lower die 7, and thus improving the processing accuracy and quality. A fixing mechanism is provided on the top of the base 1.

[0031] Referring to Figure 2 - Figure 3, the fixing mechanism includes a bracket 11, which is fixedly installed on the top of the base 1. The fixing mechanism further includes a threaded rod 13 arranged in an inclined state. The threaded rod 13 passes through and is threadedly installed on the inner wall of the bracket 11. The number of the threaded rods 13 is set to two groups. On the mutually remote sides of the two groups of threaded rods 13, a knob 12 is fixedly connected. The circumferential surface of the knob 12 is provided with anti-slip key patterns, which are used to increase the friction between the palm and the knob 12, reduce the possibility of slipping, and facilitate labor saving. On the mutually close sides of the threaded rods 13, a slider 14 is rotatably connected. The slider 14 is slidably installed on the outer wall of the bracket 11. The sliding direction of the slider 14 is the axial direction of the bracket 11. On the side of the slider 14 away from the bracket 11, a clamping plate 15 for limiting and fixing the lower mold 7 is fixedly connected. On the side of the clamping plate 15 away from the slider 14, an anti-slip groove 16 for increasing the friction on the surface of the lower mold 7 is provided, so as to improve the stability of clamping and fixing. On the front surface of the base 1, a controller 17 for the staff to view and operate the working state of the equipment is fixedly connected.

[0032] Referring to Figure 3 , the number of the positioning rods 10 is set to multiple. The multiple positioning rods 10 are symmetrically arranged on the inner wall of the slot 9. The top of the positioning rod 10 is provided with an arc surface. The lower mold 7 is inserted on the outer wall of the positioning rod 10. There is a groove at the bottom of the lower mold 7 that matches the positioning rod 10. By inserting the lower mold 7 on the outer wall of the positioning rod 10, the installation accuracy can be improved. At the same time, the top of the positioning rod 10 is provided with an arc surface. During the process of pressing the lower mold 7 downward, the arc surface contacts the edge of the groove, so as to guide the positioning rod 10 to more easily align and enter the inside of the groove, increasing the simplicity of installation.

[0033] Referring to Figure 3 , the bracket 11 is set to be U-shaped. The bracket 11 plays a role of stable support. The bracket 11 is arranged in an inclined state. The inclination degree of the bracket 11 is the same as that of the threaded rod 13. The number of the brackets 11 is set to two groups. The two groups of brackets 11 are symmetrically arranged on the left and right sides of the workbench 8.

[0034] Referring to Figure 1 , the pressing mechanism includes a support column 2, which is fixedly installed on the top of the base 1. The top of the support column 2 is fixedly connected with a top plate 3 arranged in a horizontal state. The pressing mechanism further includes an electric cylinder 4, which is installed on the top of the top plate 3. The bottom of the output shaft of the electric cylinder 4 is fixedly connected with a transmission shaft 5 arranged in a vertical state. The transmission shaft 5 passes through and is slidably installed on the inner wall of the top plate 3. The sliding direction of the transmission shaft 5 is up and down sliding. The bottom of the transmission shaft 5 is fixedly connected with an upper mold 6 that matches the lower mold 7.

[0035] Working principle: During use, place the lower die 7 adapted to the size of the gas meter seal ring on the workbench 8, align the groove at the bottom of the lower die 7 with the positioning rod 10, and press down the lower die 7 so that the lower die 7 is inserted on the outer wall of the positioning rod 10 to complete the preliminary installation of the lower die 7. Through the positioning of the lower die 7 by the positioning rod 10, the lower die 7 can be accurately installed at the bottom of the upper die 6, ensuring the installation accuracy of the lower die 7.

[0036] Then rotate the knob 12. The rotation of the knob 12 drives the rotation of the threaded rod 13. The rotation of the threaded rod 13 drives the slider 14 to make a linear displacement in the axial direction of the bracket 11. The displacement of the slider 14 drives the clamping plate 15 to approach the lower die 7 and contact the surface of the lower die 7 through the anti-slip groove 16. The self-locking function of the threaded rod 13 is used to improve the stability of clamping. The setting of the anti-slip groove 16 improves the friction with the surface of the lower die 7 and further improves the stability of clamping. Then start the power supply of the electric cylinder 4 so that the transmission shaft 5 drives the upper die 6 to move downward, so that the upper and lower watch cases are mutually attached, and then riveting work is carried out on the watch cases.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
