[0030] 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 、 Figure 3 、 Figure 4 , an embodiment provided by the present utility model: a double-station gas meter housing injection mold, including an upper mold 1. Two injection pipes 13 are fixedly connected to the top of the upper mold 1. The injection pipes 13 are responsible for injecting molten plastic into the mold cavity. The two injection pipes 13 can work independently or synchronously to meet the injection requirements of the double station and improve production efficiency. An electric push rod 2 is fixedly connected to the top of the upper mold 1. The electric push rod 2 has high-precision adjustment ability and can precisely control the opening and closing of the mold, thereby ensuring uniform filling of the plastic in the mold. The driving end of the electric push rod 2 is fixedly connected to a telescopic rod 3. The telescopic rod 3 can be telescoped up and down under the drive of the electric push rod 2. The other end of the telescopic rod 3 is fixedly connected to a lifting shell 4. Two rotating rods 5 are rotatably connected to the inner walls on the left and right sides of the lifting shell 4. The other end of the rotating rod 5 is rotatably connected to a sliding plate 6. The rotating rod 5 is responsible for providing rotational support in the lifting shell 4. The rotating function of the rotating rod 5 enables the sliding plate 6 to move smoothly along a specific track. The sliding plate 6 realizes smooth movement through the rotation of the rotating rod 5. Two grooves 7 are respectively opened on the adjacent sides of the two sliding plates 6. The grooves 7 are used to accommodate and guide the other end of the rotating rod 5, enabling the sliding plate 6 to move stably in the mold, reducing friction and wear. The other end of the rotating rod 5 is rotatably connected inside the groove 7. The rotational connection design inside the groove 7 ensures the smooth movement of the sliding plate 6 and reduces vibration and error during the movement process.

[0032] On both inner walls of the upper mold 1, a plurality of limiting rods 12 are fixedly connected. The limiting rods 12 are used to limit the movement range of the sliding plate 6 and prevent the sliding plate 6 from derailing during movement, which may cause damage to the internal mechanism of the upper mold 1. The inner parts of both sliding plates 6 are slidably connected to the outer walls of the plurality of limiting rods 12. On the other side of the sliding plate 6, a support plate 8 is fixedly connected. On the other side of the support plate 8, a transmission column 9 is fixedly connected. At the other end of the transmission column 9, a top block 10 is fixedly connected. The transmission column 9 is connected through the support plate 8 and is responsible for transmitting force to the top block 10 to achieve precise ejection of the product and smooth opening of the mold. The outer wall of the top block 10 is in contact with the inner wall of the upper mold 1. When the top block 10 contacts the inner wall of the upper mold 1, the pressure is evenly distributed through the action of the transmission column 9 to ensure the sealing of the mold and complete filling of the plastic during the injection molding process. On the left and right ends inside the upper mold 1, two springs 11 are respectively fixedly connected. The other ends of the springs 11 are fixedly connected to the outer wall of the support plate 8. The connection design of the springs 11 and the support plate 8 ensures reliable support and stability of the mold under different working conditions, reduces wear and deformation of the mold. On the outer wall of the upper mold 1, a positioning component is fixedly connected for improving the injection molding accuracy.

[0033] Referring to Figures 1 to 3 , the positioning component includes two lower molds 17 and a plurality of first connecting bars 15. The positioning component is a mechanical device used to ensure the accurate relative positions of all parts during processing. The outer walls on both sides of the upper mold 1 are respectively in contact with the outer walls on the similar sides of the two lower molds 17. The upper mold 1 is the upper structure in the component, and the outer walls on both sides are designed to be in contact with the outer walls on the similar sides of the lower molds 17. This design ensures that the upper mold 1 and the lower molds 17 can be closely fitted during the assembly process, enhancing the overall stability and accuracy. The outer walls of the plurality of first connecting bars 15 are fixedly connected to the outer wall of the upper mold 1, enhancing the rigidity of the overall system and preventing the upper mold 1 from moving or tilting due to the forces generated during operation. A plurality of positioning grooves 16 are formed on the outside of the first connecting bars 15. On the outer walls on both sides of the upper mold 1, a plurality of positioning cylinders 14 are respectively fixedly connected. The positioning cylinders 14 provide additional support and guiding functions for the upper mold 1, ensuring the stability and accuracy during positioning. On the left and right sides of the lower molds 17, two second connecting bars 18 are respectively fixedly connected. The outer walls of the first connecting bars 15 are in contact with the outer walls of the second connecting bars 18. A plurality of positioning balls 19 are fixedly connected to the outside of the second connecting bars 18. The positioning grooves 16 and the positioning balls 19 cooperate for precise positioning, which is crucial for ensuring the accuracy of the mold and avoiding errors during the production process. The outer wall of the positioning ball 19 is in contact with the inner wall of the positioning groove 16. The contact between the outer wall of the positioning ball 19 and the inner wall of the positioning groove 16 increases the positioning accuracy of the system, avoids deviations caused by movement or vibration, and improves the overall accuracy of the mold.

[0034] On the relatively close sides of the two lower molds 17, a plurality of sliding grooves 20 are respectively formed. The outer wall of the positioning cylinder 14 is slidably connected to the inside of the sliding groove 20. The positioning cylinder 14 smoothly moves within the sliding groove 20, making the positioning process more precise and stable. At the same time, the friction and wear during operation are reduced. Inside the relatively close sides of the two lower molds 17, a plurality of positioning columns 21 are respectively fixedly connected. The positioning columns 21 are slidably connected to the inner wall of the positioning cylinder 14. The positioning columns 21 provide additional support and help further fix and guide the positioning cylinder 14, making the positioning of the entire system more stable and reliable.

[0035] Working principle: When it is necessary to inject mold the gas meter housing, align the positioning balls 19 on the two lower molds 17 with the positioning grooves 16, and make the positioning columns 21 inside the upper mold 1 enter the positioning cylinder 14 of the upper mold 1, so as to make the connection between the upper mold 1 and the two lower molds 17 tight, preventing the injection molding from failing due to the gap between the upper mold 1 and the lower mold 17. Then inject the raw material into the injection molding pipe 13, and then through the action of the electric push rod 2, make the telescopic rod 3 move upward, thereby driving the lifting shell 4 and the rotating rod 5 to move upward together. Since the rotating rod 5 is connected to the sliding plate 6 through the groove 7 and the rotational connection, when the rotating rod 5 moves upward, it will drive the two sliding plates 6 to slide inward along the limiting rod 12. At the same time, the support plate 8 will also move inward with the sliding plate 6, and then through the action of the transmission column 9, drive the top block 10 into the upper mold 1 and stretch the spring 11, avoiding affecting the injection molding model. When the injection molding cools down, the electric push rod 2 operates to drive the telescopic rod 3 to move downward, and then drive the lifting shell 4 and the rotating rod 5 to move downward, and then drive the two sliding plates 6 to move outward, and the spring 11 returns to its original shape and drives the top block 10 to move outward through the transmission column 9, so as to eject the gas meter housing after injection molding and eject the two upper molds 1, so that the upper mold 1 is separated from the lower mold 17, and the finished product falls out from the gap between the upper mold 1 and the lower mold 17, thus ensuring the continuity of the injection molding process.

[0036] 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 recorded 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 within the protection scope of the present invention.
