[0016] The preferred left cover plate 1 and right cover plate 16 are respectively connected to the opening and closing mold mechanisms on the left and right sides of the vulcanizer, the left toe ring upper mold 2, the middle mold upper part 4 and the right toe ring upper mold 14 are respectively connected to the upper guide rod for installing the vulcanizer mold, the left toe ring lower mold 3, the middle mold lower part 5 and the right toe ring lower mold 15 are respectively connected to the lower guide rod for installing the vulcanizer mold, the steam inlet interface 23 and the steam outlet interface 24 are respectively connected to the steam inlet pipe and the steam recovery pipe, the superheated steam circulates in the mold steam chamber 21, and the superheated steam provides a heating medium for the mold, the internal pressure inlet 27 is connected to the nitrogen pipe, and the high-temperature and high-pressure nitrogen is used to shape the rubber parts and provide the vulcanization internal pressure and vulcanization internal temperature.
[0017] Working principle of this utility model:
[0018] Mold preheating: First, the left cover plate 1, the left toe ring upper mold 2 and the left toe ring lower mold 3, the middle mold upper part 4 and the middle mold lower part 5, the right toe ring upper mold 14 and the right toe ring lower mold 15 and the right cover plate 16 are tightly fitted through their respective mating surfaces. Steam enters the steam chamber through the steam inlet 23 to heat the mold until it reaches the process temperature;
[0019] Vulcanization preparation process: First, after starting the vulcanizer, the left cover plate 1 and the right cover plate 16 are moved outward and opened respectively, and then the left toe ring upper mold 2, the middle mold upper part 4 and the right toe ring upper mold 14 are moved upward and opened simultaneously;
[0020] Mold closing process: First, the air spring rubber part to be vulcanized is loaded into the mold cavity. Then, the left toe ring upper mold 2, the middle mold upper part 4 and the right toe ring upper mold 14 are simultaneously moved downward to combine with their respective lower parts. The positioning ring 19 on the upper part of the mold interacts with the positioning pin 20 on the lower part of the mold and is tightly fastened. Subsequently, the combined left toe ring upper mold 2 and left toe ring lower mold 3 and the right toe ring upper mold 14 and right toe ring lower mold 15 are simultaneously moved outward. At the same time, the left cover plate 1 and the right cover plate 16 move inwards. When the left cover plate 1 is combined with the left toe ring upper mold 2 and the left toe ring lower mold 3, and the right cover plate 16 is combined with the right toe ring upper mold 14 and the right toe ring lower mold 15, the left cover plate 1 pushes the left toe ring upper mold 2 and the left toe ring lower mold 3 inwards, and the right cover plate 16 pushes the right toe ring upper mold 14 and the right toe ring lower mold 15 inwards until the mold assembly is fully closed. Then, high-temperature and high-pressure nitrogen enters through the internal pressure inlet 27, and the vulcanization process begins.
[0021] Mold opening process: After vulcanization is completed, the high-temperature and high-pressure nitrogen is discharged through the internal pressure air inlet 27, and the left cover plate 1 and the right cover plate 16 are moved outward to open respectively. The left toe ring lower mold 3, the middle mold lower part 5 and the right toe ring lower mold 15 remain in their original positions. Then, the left toe ring upper mold 2, the middle mold upper part 4 and the right toe ring upper mold 14 are moved upward to open at the same time. At this time, the vulcanized empty elastic spring rubber part is taken out.
[0022] In addition, when producing air spring products of multiple specifications, when preparing the mold, the upper part 4 of the middle mold is respectively installed with the left interchangeable mold upper part 6 and the right interchangeable mold upper part 10 through bolts 8, and the lower part 5 of the middle mold is respectively installed with the left interchangeable mold lower part 7 and the right interchangeable mold lower part 11 through bolts 8. At this time, the mold can produce air spring product A; when the bolts 8 are removed from the upper part 4 of the middle mold to remove the left interchangeable mold upper part 6 and the right interchangeable mold upper part 10, and the bolts are removed from the lower part 5 of the middle mold to remove the left interchangeable mold lower part 7 and the right interchangeable mold lower part 11, the mold can produce air spring product B. Furthermore, by installing interchangeable mold parts of different sizes in the middle mold, air spring products of different specifications can be produced.
