Description

Technical Field

[0001] The utility model relates to the technical field of a plugging device for a centrifugal casting pipe mold, in particular to a plugging device for a centrifugal casting pipe mold. Background Art

[0002] Centrifugal casting is a technique and method of injecting liquid metal into a high-speed rotating mold, so that the molten metal performs centrifugal motion to fill the mold and form a casting. Due to the centrifugal motion, the liquid metal can fill the mold well in the radial direction and form a free surface of the casting; a cylindrical inner hole can be obtained without a core; it helps to remove gas and inclusions in the liquid metal; it affects the crystallization process of the metal, thereby improving the mechanical and physical properties of the casting. In the centrifugal casting process, the ends of the furnace tube mold need to be sealed with end covers to prevent the molten metal from splashing and solidifying at both ends of the mold and affecting the tube pulling. At present, the end covers are generally fixed by detachable pins. This method has a poor sealing effect and affects the flatness of the ends of the pipe fittings.

[0003] A centrifugal casting furnace tube mold disclosed in the Chinese utility model patent application disclosure CN219881255U solves the problem of poor pin fixing effect, but the centrifugal casting furnace tube mold still has the following disadvantages: First, when the above-mentioned centrifugal casting furnace tube mold is used to seal the tube mold, a threaded connection is used to combine the movable plate and the sealing plate to achieve locking of the sealing plate. When using the threaded connection, workers need to rotate the movable plate many times to move it, which is not only time-consuming but also labor-consuming, and is not conducive to use; Second, in order to prevent the tube mold from being thrown off during high-speed rotation and causing the internal high-temperature solution to spill, a layer of protection is usually provided on the outside. Since the cover plate is separated from the tube body, the protection needs to be manually installed each time it is used, which is time-consuming and requires finding parts for installation, which is not conducive to use.

A feed pipe 2 is provided on the right side of the tube body 1. A solenoid valve 3 is provided on the outside of the feed pipe 2. A feed hopper 4 is fixedly connected to the end of the feed pipe 2 away from the tube body 1. The right side wall of the second fixed sleeve 7 is flush with the right side wall of the first fixed sleeve 5. The third fixed sleeve 9 is arc-shaped. The inner wall of the third fixed sleeve 9 is in close contact with the outer wall of the tube body 1. There are two third fixed sleeves 9. The third fixed sleeve 9 is symmetrical with the tube body 1 up and down. A fixed rod 10 is fixedly connected to the third fixed sleeve 9 in a clockwise direction. The fixed rod 10 is square. A second groove is opened on the left side of the fixed rod 10. The inner wall of the second groove is slidably connected to a first clamping block 11.

[0027] During use, in order to prevent the tube mold from being thrown off during high-speed rotation and causing the internal high-temperature solution to spill, a layer of protection is usually provided on the outside. Since the cover plate 13 is separated from the tube body 1, the protection needs to be manually installed each time it is used, which is time-consuming and requires finding parts for installation, which is not conducive to use. Therefore, there is a sealing device for centrifugal casting tube molds.

The slider 20 is slidably connected to the inner wall of the second slide groove 18. A second spring 21 is fixedly connected to the left side of the slider 20, and a second clamping block 22 is fixedly connected to the left end of the second spring 21. The second clamping block 22 is in a table shape with a small left side and a large right side. A second clamping rod 23 is provided on the left side of the second clamping block 22, and the second clamping rod 23 passes through the left side wall of the base 15. The second clamping rod 23 is slidably connected to the inner wall of the first slide groove 17. A second clamping groove 24 is provided on the bottom of the base 15.

[0030] When in use, the existing centrifugal casting furnace pipe mold uses a threaded connection to combine the movable plate with the sealing plate to achieve locking of the sealing plate when sealing the pipe mold. When using the threaded connection, workers need to rotate the movable plate multiple times to move it, which is not only time-consuming but also labor-consuming and inconvenient to use. Therefore, there is a sealing device for centrifugal casting pipe molds. When the casting pipe mold needs to close the cover plate 13, the first clamping rod 16 is aligned with the first slide groove 17 and inserted. After the first clamping rod 16 enters the first slide groove 17, the cover plate 13 is rotated clockwise from right to left so that the fixed block enters the fixed groove, and then the slider 20 is moved upward to move the second clamping block 22 out of the second slide groove 18. Subsequently, the second clamping block 22 is locked with the first slide groove 17 due to the elastic force of the second spring 21. The left inner wall of the first slide groove 17 is tightly attached. At this time, the first clamping rod 16 cannot move because the second clamping block 22 is located at the inner bottom wall of the first slide groove 17 and the bottom of the first clamping rod 16. The cover plate 13 is fixed to the tube body 1. When the tube mold is used and the cover plate 13 needs to be opened, the second clamping rod 23 is pushed from left to right, so that the second clamping block 22 moves from left to right, the second spring 21 contracts, and then the slider 20 moves from top to bottom. Because the second clamping block 22 is a table-shaped setting with a small left and a large right, the slider 20 and the second clamping block 22 can smoothly enter the second slide groove 18, and then the cover plate 13 is rotated counterclockwise from right to left, the fixed block slides out of the fixed groove, and then the handle 14 is pulled to move the cover plate 13 to the right, so that the first clamping rod 16 slides out of the first slide groove 17. At this time, the cover plate 13 is separated from the tube body 1.
