Description

Technical Field

[0001] The utility model relates to the technical field of vacuum vulcanizers, in particular to a vacuum vulcanizer for rubber ring production. Background Technique

[0002] Vulcanization processing is an essential processing link in rubber ring production, and a vacuum vulcanizer is a machine for vulcanizing various rubber and plastic products, with functions such as timing mold clamping, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. The vulcanizer is divided into three forms: electric heating, steam heating, and heat-conducting oil heating, and integrates functions such as preheating required for the rubber vulcanization process, automatic exhaust after feeding, pressure-holding vulcanization, timing alarm, automatic mold opening, and product demolding, and is widely applicable to the rubber processing industry.

[0003] After the injected material in the template of the existing vacuum vulcanizer is vulcanized and formed, it is usually necessary for workers to reach into the device by hand to disassemble the rubber that has completed the vulcanization operation on the heating plate. This not only does not have enough space for convenient disassembly by personnel, but also poses certain safety hazards to the operators to a certain extent. For this reason, we propose a vacuum vulcanizer for rubber ring production to solve the above problems. Summary of the Invention

[0004] The purpose of the utility model is to provide a vacuum vulcanizer for rubber ring production to solve the problems raised in the above background technique.

[0021] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, in the present utility model, a vacuum vulcanizing machine for rubber ring production includes a bottom plate 1 and a lower mold 4. A cavity 19 is formed inside the lower mold 4. Three first electric push rods 16 are fixedly installed on the inner bottom wall of the cavity 19. A disc 15 is fixedly installed at the output ends of the three first electric push rods 16. A number of ejector rods 14 arranged in a ring are fixedly installed on the upper surface of the disc 15. An annular mold groove 12 is formed on the upper surface of the lower mold 4. A number of ejector holes 17 arranged in a ring are formed on the inner bottom wall of the annular mold groove 12. The top end of each ejector rod 14 extends into the interior of the ejector hole 17. The three first electric push rods 16 together support the disc 15. Workers can inject rubber melt into the interior of the annular mold groove 12 through the input port formed on the upper surface of the top seat 6. The rubber melt can form a closed body as it flows within the annular mold groove 12. The output ends of the three first electric push rods 16 can extend together to lift the disc 15 and the ejector rods 14 on the upper surface of the disc 15. The multiple ejector rods 14 can together lift the vulcanized rubber ring.

[0023] An annular groove 13 is formed on the upper surface of the lower mold 4. A heater 11 is fixedly installed on the inner bottom wall of the annular groove 13. The annular groove 13 can accommodate the heater 11. A base 2 is fixedly installed on the upper surface of the bottom plate 1. Four support rods 5 and two second electric push rods 3 are respectively fixedly installed on the upper surface of the base 2. The output end of each second electric push rod 3 is fixedly installed with the bottom surface of the lower mold 4. The output ends of the two second electric push rods 3 can together drive the lower mold 4 to lift and lower. The top ends of the four support rods 5 are fixedly installed with a top seat 6. An upper template 7 is fixedly installed on the bottom surface of the top seat 6. The four support rods 5 together support the top seat 6. While injecting rubber melt into the interior of the annular mold groove 12, the vacuum machine inside the console 10 can extract the air inside the annular mold groove 12 through the vacuum extraction port inlaid on the upper template. After the bottom surface of the upper template 7 contacts the upper surface of the lower mold 4, it can cover the annular mold groove 12, thereby effectively preventing the rubber melt inside the annular mold groove 12 from leaking during the vulcanization process.

[0024] Four sliding holes 18 are formed on the upper surface of the lower mold 4. The outer surface of each support rod 5 is slidably connected to the inner wall of the sliding hole 18. By forming four sliding holes 18 on the upper surface of the lower mold 4 and making the inner wall of each sliding hole 18 slidably connected to the outer surface of the support rod 5, the lower mold 4 can maintain stability when lifting and lowering. A console 10 is fixedly installed on the upper surface of the bottom plate 1. A controller 9 and a display screen 8 are respectively fixedly installed on the front surface of the console 10. Workers can control the device through the controller 9.

[0025] The working principle of the present utility model is:

[0026] When it is necessary to take out the vulcanized rubber ring, the staff first controls the output ends of the two second electric push rods 3 to contract through the controller 9. The contraction of the output ends of the two second electric push rods 3 drives the lower mold 4 to descend together. Then, the staff controls the output ends of the three first electric push rods 16 to extend through the controller 9. The extension of the output ends of the three first electric push rods 16 drives the disc 15 to rise together. The rising of the disc 15 can drive the multiple annularly arranged ejector rods 14 to rise. The multiple annularly arranged ejector rods 14 can eject the vulcanized rubber ring out of the annular die groove 12.

[0027] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0028] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
