Description

Technical Field

[0001] This utility model relates to the technical field of angle control valves, and in particular to a casting mold for rapid shaping of the valve body of an angle control valve. Background Technology

[0002] Angle control valves are commonly used industrial automation control devices. They use pneumatic actuators to control the opening and closing of the valve, regulating parameters such as flow rate and pressure of the medium in the pipeline. They require casting equipment for casting, but angle control valves are prone to internal shrinkage and cracking defects. The valve body has many ribs and numerous intersecting thin and thick walls, making it susceptible to internal shrinkage and cracking defects at these junctions. Furthermore, the difference between the thicker parts of the valve body and the wall thickness is significant, leading to a severe tendency for solidification heat cracking. As angle control valve bodies are pressure vessels, they are prone to leakage during use, thus requiring high internal quality. Therefore, a rapid-setting casting mold is particularly needed for casting angle control valve bodies.

[0003] Currently, in traditional angle control valve casting equipment, the valve body is fed into the 45-degree gating system, which causes instability in the molten steel entering the valve body. This leads to sandblasting and bottom shortening, resulting in more casting defects and affecting the overall quality and performance of the angle control valve. Therefore, the cast angle control valve needs to undergo further processing and treatment to improve its crack resistance. However, this not only increases production costs but also reduces production efficiency. Utility Model Content

[0018] 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.

[0019] Please see Figure 1-4This utility model provides a technical solution: a casting mold for rapid shaping of an angle regulating valve body, comprising a riser 1, an angle regulating valve body 2, an ingate 3, a horizontal runner 4, a vertical runner 5, and a sealing mechanism 6. The bottom of the riser 1 is provided with the angle regulating valve body 2, and the bottom of the angle regulating valve body 2 is provided with the ingate 3. One end of the ingate 3 is connected to the horizontal runner 4, and the other end of the horizontal runner 4 is connected to the vertical runner 5. The sealing mechanism 6 is provided inside the vertical runner 5. The sealing mechanism 6 includes a sealing plate 61, a first sealing ring 62, a connecting plate 63, a fixing shell 64, a first bolt 65, a connecting shell 66, a second bolt 67, a second sealing ring 68, and a fixing plate 69. 9. A sealing plate 61 is provided inside the sprue 5. A first sealing ring 62 is fitted on the outer wall of the sealing plate 61. A connecting plate 63 is fitted on the outside of the sealing plate 61. A fixing shell 64 is provided outside the sealing plate 61. A first bolt 65 is provided on the fixing shell 64. A connecting shell 66 is provided outside the fixing shell 64. A second bolt 67 is provided outside the connecting shell 66. A second sealing ring 68 is fitted outside the connecting shell 66. Through the arrangement of the sealing plate 61, the first sealing ring 62, the connecting plate 63, the fixing shell 64, the first bolt 65, the connecting shell 66, the second bolt 67, the second sealing ring 68, and the fixing plate 69, the sealing mechanism 6 can ensure that the casting mold is in use. To achieve a good sealing effect and prevent molten steel leakage during casting, ensuring smooth casting, when sealed casting is required, firstly, the sealing plate 61 is placed inside the sprue 5. Then, the first sealing ring 62 is fitted onto the outer wall of the sealing plate 61. Utilizing the elasticity of the first sealing ring 62, the inner wall of the first sealing ring 62 is tightly fitted against the outer wall of the sealing plate 61. Next, the connecting plate 63 is fitted onto the outside of the sealing plate 61, and the fixing shell 64 is placed onto the outside of the connecting plate 63. At this time, the inner wall of the fixing shell 64 is in contact with the outer wall of the connecting plate 63. The first bolt 65 passes through the fixing shell 64 and connects it to the sealing plate 61, thereby connecting the fixing shell 64 and the sealing plate 61. 61 is fixed, and then the connecting shell 66 is placed outside the fixed shell 64. At this time, the inner wall of the connecting shell 66 is in contact with the outer wall of the fixed shell 64. The second bolt 67 is used to pass through the connecting shell 66 and connect it to the sealing plate 61, thereby fixing the connecting shell 66 and the sealing plate 61. Then, the second sealing ring 68 is sleeved on the outside of the connecting shell 66. The elasticity of the second sealing ring 68 makes the inner wall of the second sealing ring 68 fit tightly with the outer wall of the connecting shell 66. Then, the fixing plate 69 is placed outside the second sealing ring 68. The fixing plate 69 is used to limit the second sealing ring 68 and prevent the second sealing ring 68 from falling off, thereby completing the installation of the sealing mechanism 6.

[0020] Furthermore, the outer wall size of the sealing plate 61 matches the inner wall size of the first sealing ring 62, and the outer wall size of the sealing plate 61 matches the inner wall size of the connecting plate 63. The connecting plate 63 can limit the sealing plate 61 and prevent the sealing plate 61 from shifting inside the straight channel 5, thus affecting the sealing effect.

[0021] Furthermore, the outer wall dimensions of the fixed shell 64 match the inner wall dimensions of the sealing plate 61. The first bolt 65 passes through the fixed shell 64 and is connected to the sealing plate 61. The setting of the first bolt 65 enables the fixed shell 64 to be firmly connected to the sealing plate 61, ensuring the stability of the sealing mechanism 6.

[0022] Furthermore, the outer wall dimensions of the connecting shell 66 match the inner wall dimensions of the fixed shell 64. The second bolt 67 passes through the connecting shell 66 and connects to the sealing plate 61. The setting of the second bolt 67 further enhances the stability of the sealing mechanism 6, enabling the connecting shell 66 to be tightly connected to the fixed shell 64 and fixed to the sealing plate 61, thereby enhancing the overall sealing performance.

[0023] Furthermore, the inner wall size of the second sealing ring 68 matches the outer wall size of the fixed shell 64, and the inner wall size of the fixed plate 69 matches the outer wall size of the second sealing ring 68. By setting the second sealing ring 68, the sealing effect of the sealing mechanism 6 is further improved, preventing molten steel from leaking from the gap between the connecting shell 66 and the fixed shell 64 during the casting process, thus ensuring the accuracy and quality of the casting.

[0024] Furthermore, the first bolts 65 are arranged in a ring array on the outer wall of the fixed shell 64, and the second bolts 67 are arranged in a ring array on the outer wall of the connecting shell 66. The connection strength between the fixed shell 64 and the sealing plate 61 is enhanced by the setting of the connecting shell 66, thereby improving the stability of the sealing mechanism 6.

[0025] Furthermore, the inner wall dimensions of the sprue 5 match the outer wall dimensions of the sealing plate 61. The sealing plate 61 is designed to fit tightly against the inside of the sprue 5, preventing molten steel from leaking from the gap between the sprue 5 and the sealing plate 61 during the casting process, thus further ensuring the accuracy and quality of the casting.

[0026] Working Principle: During use, first ensure all components are correctly installed and tightened. Molten steel flows in through the sprue 5. Because the inner wall dimensions of the sprue 5 match the outer wall dimensions of the sealing plate 61, the molten steel is effectively guided and leakage is prevented. The sealing plate 61, along with its first sealing ring 62, connecting plate 63, and other components, forms a tight sealing system, ensuring the stability and accuracy of the molten steel during casting. As the molten steel flows in, it further passes through the sprue 4 and ingate 3, ultimately entering the mold cavity of the angle regulating valve body 2. In this process, the sealing mechanism 6 not only prevents molten steel leakage but also, through its robust structural design, ensures the stability and durability of the mold during casting.

[0027] After casting, once the mold has cooled and solidified, it can be opened to remove the formed angle control valve body. Because the mold design takes into account the complex structure and quality requirements of the angle control valve body, the resulting valve body will have fewer internal defects, such as shrinkage cavities and cracks, thus improving the overall quality and performance of the product.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
