Technical Field

[0001] The utility model relates to the technical field of ingates, in particular to a plug used for cleaning ingates. Background Art

[0002] The ingentrant is the general term for the channel through which liquid metal enters the mold cavity in the casting, and the ingentrant is the last section of the channel for liquid metal to enter the mold cavity. It mainly controls the speed and direction of the molten metal filling the mold, adjusts the temperature of each part of the mold and the solidification sequence of the casting, and has a certain shrinkage compensation effect on the casting. There can be a single or multiple ingentrants.

[0003] Most of the plugs are used at both ends of the ingrowth to keep the inside of the ingrowth clean. Therefore, the common plugs must not only consider the sealing performance of the plugging, but also the convenience of operation, especially the disassembly and assembly of the plugs, which usually requires the use of tools. Therefore, when the plugs in the prior art are used, most of them can only be disassembled and assembled with one tool, which makes it inconvenient to use. Therefore, we propose a plug for not cleaning the ingrowth to solve the above problems. Utility Model Content

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4 As shown, a plug for not cleaning the inner runner comprises an integral structure 1 and an auxiliary structure 2, wherein the auxiliary structure 2 is located at the front and rear positions on both sides of the top of the integral structure 1; the integral structure 1 comprises a plug hanging platform 101, wherein the outer surface of the plug hanging platform 101 is fixedly connected with a hexagonal plate 102 near the top position, a first circular groove 103 is provided at the top center of the hexagonal plate 102, an operating block 104 is fixedly connected at the inner bottom center of the first circular groove 103, a second circular groove 108 is provided at the inner surface of the plug hanging platform 101 near the bottom position, a plurality of uniformly distributed micro springs 109 are fixedly connected to the inner top of the second circular groove 108, a connecting disc 110 is provided at the bottom of the micro spring 109, and a rubber sealing ring 107 is fixedly connected at the bottom center of the connecting disc 110.

[0024] The effect achieved by the entire embodiment 1 is as follows: Figure 1 As shown, when the user needs to disassemble the whole, the user can use the hexagonal plate 102 to cooperate with the hexagonal or quadrilateral wrench to twist the whole, and finally complete the disassembly, and then Figure 1 As shown, through the cooperation of the operating block 104, the user can use a flat-head or cross-shaped screwdriver to twist the whole body, and finally complete the disassembly, thereby avoiding the need for the user to use multiple tools to disassemble the whole body, so that the subsequent disassembly and assembly will not take too much time each time, which is more convenient for the user to use and also increases the overall disassembly and assembly efficiency. Figure 2 and Figure 3 As shown, when the overall installation is completed, the rubber sealing ring 107 will contact the outer surface of the ingrowth, and the micro spring 109 will be under pressure. Then the rubber sealing ring 107 uses the expansion force of the micro spring 109 to effectively apply force to the ingrowth, so that it can fully fit with the outer surface of the ingrowth, and the material of the rubber sealing ring 107 is composed of fluororubber, which has good elasticity and sealing properties, so that the sealing property of the connection between the plug hanger 101 and the ingrowth can be increased.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, one end of the micro spring 109 is fixedly connected to the top surface of the connecting disk 110, the other end of the micro spring 109 is fixedly connected to the inner top of the second circular groove 108, the outer surface of the rubber sealing ring 107 is slidably connected to the inner surface of the plug hanging platform 101, and the plug body 105 is fixedly connected to the bottom center of the plug hanging platform 101. The outer surface of the plug body 105 is provided with an external thread 106, and the auxiliary structure 2 includes a conveying pipe 201. The inner wall of the conveying pipe 201 is slidably connected with a sealing cover 202 near the top position, and the outer surface of the conveying pipe 201 is fixedly connected to the inner surface of the plug hanging platform 101.

[0026] The effect achieved by the entire embodiment 2 is that, in the subsequent actual use process, the material of the plug body 105 is composed of high-aluminum cast iron, which can provide better barrier effect in high temperature and corrosive environment, reduce the possibility of penetration and erosion of the plug, and thus extend the service life of the plug body 105, and the outer surface of the plug body 105 is also surface-treated by a coating method, so that a corrosion-resistant protective layer is formed on the outer surface of the plug to reduce erosion when in contact with the molten metal, and through the setting of the external thread 106, the whole can normally engage with the internal thread on the inner runner, and then complete the connection with the inner runner, then through the cooperation of the delivery pipe 201 and the sealing cover 202, it is convenient for the user to inject lubricating oil into the external thread 106, then after the injection is completed, the friction of the threaded part can be reduced, making the whole easier to disassemble.

[0027] Working principle: First, the user uses the external thread 106 to engage the plug body 105 with the internal thread on the ingrowth. After the engagement, the connection between the whole and the ingrowth is completed. During the engagement process, the rubber sealing ring 107, the connecting disc 110 and the micro spring 109 are stressed and can slide in the second circular groove 108. Then, after the connection is completed, the rubber sealing ring 107 can use the expansion force of the micro spring 109 to effectively apply force to the ingrowth, so that the rubber sealing ring 107 can fully contact the outer surface of the ingrowth, thereby increasing the sealing of the connection between the whole and the ingrowth, and reducing the possibility of penetration and erosion. When the whole needs to be disassembled later, the user first takes out the sealing cover 202, and then pours the lubricating oil into the delivery pipe 201. The lubricating oil is transported through the delivery pipe 201 and finally can be transported to the external thread 106, so as to reduce the friction of the threaded part, making it easier to disassemble later. Then, through the setting of the hexagonal plate 102, the user can use a hexagonal or quadrilateral wrench to twist the whole to complete the disassembly. At the same time, through the setting of the operating block 104, the user can also use a flat or cross screwdriver to twist the whole to complete the disassembly. After the whole is removed, it is avoided that multiple tools are needed for operation.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
