Description

Technical Field

[0001] This utility model relates to the field of casting tank technology, and in particular to a vacuum casting tank with high sealing performance. Background Technology

[0002] Vacuum casting is a method of casting molten steel, which is melted in the atmosphere, into an ingot mold in a vacuum chamber. It is also called vacuum ingot casting.

[0003] In industrial production, vacuum casting jars are commonly used as vacuum chambers. A vacuum casting jar consists of a jar body and a sealing lid, with a vacuum casting device mounted on the outer wall of the jar. A mold is installed inside the jar, which is then sealed with the lid. A vacuum is then created to reduce the pressure inside the jar to the required process pressure. Molten steel is then poured into the mold through the vacuum casting device. Once the molten steel solidifies, the finished workpiece is obtained.

[0004] During the steel casting process, insufficient sealing in some casting jars can lead to excessive pressure rise inside the jar, thus affecting the casting effect. Therefore, there is a need to provide a vacuum casting jar with high sealing performance. Utility Model Content

[0005] In view of the above problems, this utility model provides a vacuum casting tank with high sealing performance.

[0018] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0019] This application discloses a vacuum casting vessel with high sealing performance, referring to... Figure 1 , Figure 2 and Figure 3 The container includes a tank body 1, with an opening on one side. A sealing cap 2 for sealing the opening is rotatably mounted on the outer wall of the tank body 1, and a driving member 6 for rotating the sealing cap 2. A sealing element is installed between the sealing cap 2 and the opening of the tank body 1, and a connecting member is provided on the sealing cap 2 for driving the sealing cap 2 to squeeze the sealing element and restrict the rotation of the sealing cap 2.

[0020] In this embodiment, a vacuum casting device 7 for pouring molten steel and a pressure gauge (not shown) are also installed on the tank 1. Specifically, a connecting rod is welded and fixed to the cover plate, and the cover plate is rotatably mounted on the outer wall of the tank 1 via the connecting rod. The driving component 6 includes a cylinder, the cylinder body of which is rotatably mounted on the outer wall of the tank 1. The piston rod of the cylinder is rotatably connected to the connecting rod, and the cover plate can be rotated by the cylinder to open / close the tank 1. After the operator installs the mold into the tank 1, the sealing cover 2 can be rotated by the cylinder and placed on the opening of the tank 1. Then, the sealing cover 2 can be driven by the connecting component to squeeze the sealing element and restrict the rotation of the sealing cover 2, thereby improving the sealing performance of the tank 1 and having the advantage of improving the molten steel pouring effect.

[0021] Specifically, the sealing element includes a sealing ring 3, which is disposed on the end face at the opening of the tank body 1, and the inner side of the sealing ring 3 extends into the tank body 1. The sealing ring 3 may be made of high-temperature resistant rubber material.

[0022] Furthermore, the sealing cover 2 is coaxially provided with a boss 21 for pressing contact with the inner side of the sealing ring 3, and the outer wall of the boss 21 is provided with a conical guide surface 211.

[0023] When the cover plate is placed over the opening of the tank 1, the boss 21 can be inserted into the tank 1 and press against the inner side of the sealing ring 3, which can further improve the sealing effect of the tank 1.

[0024] Specifically, the connector includes a connecting ring 4 coaxially rotatably mounted on the outer wall of the sealing cover 2, and multiple protrusions 42 are welded and fixed at intervals along the inner wall of the connecting ring 4 along its own circumference. Multiple grooves 11 are provided on the outer wall of the tank body 1 to accommodate the protrusions 42 one by one, and one end of the groove 11 extends obliquely to the end face of the opening of the tank body 1.

[0025] In this embodiment, an annular groove is formed on the outer wall of the sealing cap 2, and the connecting ring 4 is rotatably connected to the cap plate through the annular groove. When the cap plate is placed over the opening of the tank 1, the operator rotates the connecting ring 4 and causes multiple protrusions 42 to slide into the corresponding grooves 11 one by one, which further drives the sealing cap 2 to squeeze the sealing ring 3. When the protrusions 42 slide to the bottom of the grooves 11, the rotation of the sealing cap 2 relative to the tank 1 is restricted, thereby improving the sealing performance of the tank 1.

[0026] To improve the installation stability of the connecting ring 4 on the cover plate, a limiting component is also installed on the sealing cover 2 to restrict the rotation of the connecting ring 4 relative to itself. The limiting component includes a limiting pin 5, a limiting groove is formed on the outer wall of the sealing cover 2, and a limiting hole is formed on the outer wall of the connecting ring 4. The limiting pin 5 passes through the limiting hole and is inserted into the limiting groove.

[0027] In this embodiment of the application, when the multiple protrusions 42 on the connecting ring 4 slide into the bottom of the slide groove 11 one by one, the limiting hole aligns with the limiting groove, and the worker inserts the limiting pin 5 into the limiting hole and the limiting groove, which can improve the installation stability of the connecting ring 4 on the cover plate.

[0028] To facilitate the rotation of the connecting ring 4 by the staff, a handle 41 is welded on the outer wall of the connecting ring 4.

[0029] The implementation principle of a vacuum casting tank with high sealing performance according to the present application embodiment is as follows: After the operator installs the mold into the tank body 1, the driving component 6 can drive the sealing cover 2 to rotate and cover the opening of the tank body 1. Then, the connecting component can drive the sealing cover 2 to squeeze the sealing component and restrict the rotation of the sealing cover 2, thereby improving the sealing performance of the tank body 1 and having the advantage of improving the steel casting effect.
