[0002] Cast pipe fittings are susceptible to environmental influences over long periods of use, leading to oxidation and rust, which can shorten their service life. Therefore, operators pour a layer of anti-corrosion cement on the surface of cast pipe fittings to prevent corrosion. Cement's quick-drying and long-lasting properties enhance its effectiveness. It also protects cast pipe fittings from groundwater corrosion and other water chemical reactions. Cement plays a crucial role in preventing pipeline corrosion.
[0003] During the casting process, in order to achieve air conduction within the mold, it is necessary to open air guide holes at the edge of the mold. In order to prevent debris from invading the mold through the air guide holes, it is necessary to insert air guide plugs into the air guide holes to effectively prevent the intrusion of debris. However, for the convenience of processing and production, some existing casting air guide plugs will directly open exhaust grooves horizontally on the top of the air guide plugs, resulting in the end of the exhaust groove being opened to the outer diameter position of the air guide plug, thereby reducing the strength of the top of the air guide plug, making the top of the air guide plug prone to deformation and distortion, and insufficient rigidity.

[0026] As described in the background technology, in order to facilitate processing and production, the existing partially cast air guide plugs will directly open an exhaust groove horizontally on the top of the air guide plug, resulting in the end of the exhaust groove opening to the outer diameter position of the air guide plug, which in turn causes the strength of the top of the air guide plug to be reduced, making the top of the air guide plug prone to deformation, twisting, and insufficient rigidity.
[0027] In order to solve this technical problem, the utility model provides a casting air guide plug, which is used for surface protection of castings.

[0029] The plug body 1 has a venting groove 2 on the top of the plug body 1. There are multiple venting grooves 2, which are evenly arranged from the middle of the plug body 1 to the side of the plug body 1. The venting grooves 2 are evenly arranged from large to small from the middle of the plug body 1 to the side of the plug body 1. A slope 3 is provided on the top of the inner side of the plug body 1. The higher end of the slope 3 corresponds to the middle of the plug body 1, and the lower end of the slope 3 corresponds to the inner edge of the plug body 1.
[0030] The cast air guide plug provided by the present invention, through the overall structural design of the device, enables the plug body 1 to achieve the effect of sealing the air guide hole, and the exhaust groove 2 opened can help to guide the air, thereby realizing the function of the air guide plug, and the top of the inner side of the plug body 1 is provided with a slope 3, so that the top of the inner side of the plug body 1 is arched, thereby effectively increasing the pressure bearing capacity of the front side of the device, further improving the rigidity of the device, and effectively increasing the service life of the device.
[0031] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0032] Example 1:
[0033] Please refer to Figure 1 - Figure 2 , a casting air guide plug, comprising:
[0034] The plug body 1 has a venting groove 2 on the top of the plug body 1. There are multiple venting grooves 2, which are evenly arranged from the middle of the plug body 1 to the side of the plug body 1. The venting grooves 2 are evenly arranged from large to small from the middle of the plug body 1 to the side of the plug body 1. A slope 3 is provided on the top of the inner side of the plug body 1. The higher end of the slope 3 corresponds to the middle of the plug body 1, and the lower end of the slope 3 corresponds to the inner edge of the plug body 1.
[0035] In this embodiment, the outer diameter of the plug body 1 is 12 mm, the inner diameter of the plug body 1 is 9 mm, and the height of the plug body 1 is 8 mm. In other embodiments, the size of the plug body 1 can be adjusted according to needs.
[0036] In this embodiment, the thickness of the plug body 1 between the top and the highest point of the inclined surface 3 is 1 mm, and the thickness of the plug body 1 between the top and the lowest point of the inclined surface 3 is 1.4 mm. In other embodiments, the size of the plug body 1 can be adjusted according to needs.
[0037] In this embodiment, the lengths of the exhaust grooves 2 from the middle to the two sides are 8 mm, 7.71 mm, 6.93 mm, and 5.48 mm, respectively. In other embodiments, the size of the plug body 1 can be adjusted according to needs.
[0038] Through the above-mentioned structural design, the exhaust groove 2 is not opened to the outer diameter position of the plug body 1, thereby effectively ensuring that each exhaust groove 2 maintains a relatively firm connection with the plug body 1, thereby effectively improving the rigidity of the device, and an arched structure is made on the inner side to increase the pressure-bearing capacity of the front of the device, further improving the rigidity of the device, and thus effectively reducing the deformation, twisting, and insufficient rigidity of the top of the plug body 1.
[0039] Example 2:
[0040] The pouring air guide plug provided in Example 1 is further optimized. Specifically, Figure 3 As shown, a protective base 4 is further provided at the inner bottom of the plug body 1 . The cross section of the protective base 4 is in an inverted T-shape, and a vent hole 5 is provided in the middle of the protective base 4 .
[0041] Through the above structural design, the protective base 4 reduces the intrusion of smaller debris into the mold through the plug body 1, and the air guide effect is maintained through the vent hole 5.
[0042] Example 3:
[0043] The pouring air guide plug provided in Example 2 is further optimized. Specifically, Figure 3-Figure 4 As shown, a protective component is provided inside the plug body 1 and above the protective base 4. The protective component includes a blocking ball 6, a blocking ring 7, and a spring 8. The blocking ball 6 corresponds to the position of the vent 5. The outer side of the blocking ball 6 is fixedly connected to the blocking ring 7. A spring 8 is provided between the blocking ring 7 and the protective base 4. The top of the spring 8 is fixedly connected to the blocking ring 7. The bottom of the spring 8 is sleeved on the outer side of the upper part of the protective base 4. The bottom of the blocking ball 6 can fit tightly with the top of the vent 5.
[0044] Through the above structural design, when the top of the plug body 1 is severely damaged and broken, it can block the debris, so that the air guide effect can be maintained. When the debris is heavy, squeezing the blocking ball 6 downward can achieve the blocking of the vent 5, thereby completely preventing the debris from invading the interior of the mold.
