[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-3 This utility model provides an embodiment of a PET bottle blow molding machine mold opening and closing structure, including a base plate 1. Fixing blocks 2 are fixedly connected to the left and right sides of the upper part of the base plate 1. A support plate 3 is fixedly connected to the upper part of the fixing blocks 2. First mounting rods 4 are fixedly connected to the front and rear sides of the inner part of the support plate 3. First limiting sleeves 9 are fixedly connected to the outer sides of both ends of the first mounting rods 4. A first mounting plate 5 is fixedly connected to the left side of the outer part of the first mounting rods 4. Second mounting rods 8 are fixedly connected to the front and rear sides of the upper inner part of the first mounting plate 5. Second limiting sleeves 10 are fixedly connected to the outer sides of both ends of the second mounting rods 8. A connecting plate 6 is fixedly connected to the right side of the first mounting plate 5. A first mold 7 is fixedly connected to the right side of the connecting plate 6. An opening and closing mold assembly is fixedly connected to the outer right sides of the first mounting rods 4 and the second mounting rods 8 for opening and closing the blow molding machine. The opening and closing mold assembly includes a second mounting... The second mounting plate 11 is fixedly connected to the outside right side of the first mounting rod 4 and the second mounting rod 8. A cylinder 12 is fixedly connected to the right side of the second mounting plate 11. A sliding plate 13 is fixedly connected to the output end of the cylinder 12. A second mold 14 is fixedly connected to the left side of the sliding plate 13. Telescopic columns 15 are evenly fixedly connected around the left side of the second mounting plate 11. The sliding plate 13 is slidably connected to the outside of the first mounting rod 4 and the second mounting rod 8 to ensure smooth sliding operation. The first mold 7 and the second mold 14 are both made of alloy steel, which enhances the durability and stability of the mold. The sliding plate 13 is made of polytetrafluoroethylene, which further improves the smoothness of operation and service life. The end of the telescopic column 15 away from the second mounting plate 11 is fixedly connected to the sliding plate 13. The connecting plate 6 is made of stainless steel, and the second mounting plate 11 is made of aluminum alloy.

[0027] During the mold closing operation of the PET bottle blowing machine, the starting cylinder 12 is first controlled to drive the sliding plate 13 to slide along the outer side of the first mounting rod 4 and the second mounting rod 8. The sliding plate 13 pushes the second mold 14 towards the first mold 7, so that the two can fit tightly together to complete the mold closing operation. When the mold opening operation is required, the starting cylinder 12 is controlled to drive the sliding plate 13 to continue sliding. The sliding plate 13 drives the second mold 14 away from the first mold 7 to realize the mold opening. Thus, the mold opening and closing operation of the PET bottle blowing machine is completed conveniently. This process significantly improves the processing efficiency of PET bottles and ensures the efficient operation of the equipment.

[0028] Reference Figures 1-3 The base plate 1 is made of carbon steel, the fixing block 2 and the first mounting rod 4 are both made of stainless steel, and the support plate 3 is made of cast iron.

[0029] By using carbon steel to improve the strength and rigidity of the base plate 1, it can withstand greater working pressure and mechanical load, thus ensuring the stability and reliability of the base plate 1 during long-term operation. By using stainless steel to improve the strength and corrosion resistance of the fixing block 2 and the first mounting rod 4, it can effectively resist corrosive factors such as moisture and chemicals in the environment, extend the service life of the fixing block 2 and the mounting rod, and avoid damage caused by corrosion. By using cast iron to improve the rigidity and stability of the support plate 3, it reduces deformation caused by vibration and load, thereby improving the stability and reliability of the overall structure. This allows the opening and closing mold structure to better withstand complex working conditions during long-term use, thus significantly improving the durability and service life of the entire system.

[0030] Working principle: When the PET bottle blowing machine needs to perform a mold closing operation, the starting cylinder 12 is controlled to drive the sliding plate 13 to slide outside the first mounting rod 4 and the second mounting rod 8. The sliding plate 13 drives the second mold 14 to move so that it fits against the first mold 7. When the PET bottle blowing machine needs to perform a mold opening operation, the starting cylinder 12 is controlled to drive the sliding plate 13 to slide outside the first mounting rod 4 and the second mounting rod 8. The sliding plate 13 drives the second mold 14 to move away from the first mold 7. This makes it easier for the PET bottle blowing machine to open and close the mold, thus improving the processing efficiency of PET bottles.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
