[0002] Riser sleeves are made of heat-generating and heat-insulating materials. Their inner walls are identical to the outer contours of the riser column. During the casting process, they are installed on the pouring device to keep the molten metal at the pouring gate warm and to replenish the molten metal onto the casting, effectively preventing shrinkage cavities in the casting.
[0003] As disclosed in announcement number CN218192416U, a heat-insulating riser sleeve for high-alloy steel castings includes a riser sleeve body. An vent is provided on the left side of the top of the riser sleeve body. A gas guide shroud is fixedly connected to the upper part of the inner wall of the riser sleeve body, and a gas guide hole is provided in the middle of the gas guide shroud. L-shaped slots are symmetrically provided on the lower part of the inner wall of the riser sleeve body. In this invention, two locking blocks on the easy-cutting plate are inserted into the two L-shaped slots at the bottom of the riser sleeve body, and then the easy-cutting plate is rotated. At this time, a T-shaped stop limits the locking blocks inside the L-shaped slots, realizing the installation of the easy-cutting plate and the riser sleeve body, and facilitating the disassembly and reuse of the easy-cutting plate. When the molten metal inside the riser sleeve body is sprayed upwards with the gas, because the vent and the gas guide hole are not on the same axis, the molten metal sprays onto the inner top surface of the riser sleeve body and then flows back into the lower part of the riser sleeve body from the surface of the gas guide shroud.
[0004] The existing device can install the easy-cut plate and the riser sleeve body. However, with prolonged use of the elastic fixing method, if the working environment is highly vibrating, the plate is prone to falling off, which will make it impossible to quickly fix the easy-cut plate in the future.

[0007] Furthermore, the inner wall of the guide groove is in contact with the outer surface of the guide block, and a sliding connection is formed between the guide block and the guide groove.
[0008] Furthermore, the position and size of the slot match the position and size of the plug, and the plug and the slot form a mating connection.
[0009] Furthermore, the threaded rod is rotatably connected to the push plate via a bearing.
[0010] Furthermore, a filter assembly is provided on the top side of one side of the riser sleeve body. The filter assembly includes a groove, and threaded holes are provided on both sides of the groove.
[0011] Furthermore, a filter screen is provided inside the groove, and holes are opened on both sides of the filter screen, with bolts inserted into the holes.
[0012] Furthermore, the bolt through hole and the threaded hole form a threaded connection.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, when it is necessary to fix the easy-cut piece, the guide block and guide groove can be used for guidance first.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0023] Examples, such as Figure 1 - Figure 3As shown, this utility model provides an easy-to-clean and disassemble heating and insulating riser sleeve, including a riser sleeve body 1. The riser sleeve body 1 has an easy-to-disassemble component 2 inside. The easy-to-disassemble component 2 includes two sets of fixing blocks 201. Fixing blocks 201 are connected to both sides of the two sets of fixing blocks 201. A threaded rod 206 is threadedly connected inside the fixing block 201. A bearing 207 is connected to the front end of the threaded rod 206. A push plate 208 is connected to the front end of the bearing 207. An insert block 209 is connected to the front end of the push plate 208. Springs 210 are connected to both sides of the fixing block 201. The riser sleeve body... The interior of the riser sleeve body 1 is provided with an easy-cutting plate 203. Slots 205 are provided on both sides of the easy-cutting plate 203. Guide blocks 204 are connected to the front and rear ends of the easy-cutting plate 203. Guide grooves 202 are provided on the inner walls of the front and rear ends of the riser sleeve body 1. The inner wall of the guide groove 202 is in contact with the outer surface of the guide block 204. The guide block 204 and the guide groove 202 form a sliding connection. The position and size of the slot 205 match the position and size of the insert 209. The insert 209 and the slot 205 form an insertion connection. The threaded rod 206 is rotatably connected to the push plate 208 through the bearing 207.
[0024] The effect achieved in Embodiment 1 is as follows: When disassembling the easy-cut piece 203, the threaded rod 206 can be rotated forward, allowing the threaded rod 206 to rotate in the forward thread with the fixed block 201. This forward threaded rotation allows the threaded rod 206 to move outward. As the threaded rod 206 moves, it also rotates through the bearing 207 and the push plate 208, causing the push plate 208 and the insert block 209 to retract, pulling the insert block 209 out of the slot 205. At this time, the spring 210 is also under compression. After cleaning the inside of the riser sleeve body 1, it is necessary to... When installing the easy-cut disc 203, first align the guide block 204 of the easy-cut disc 203 with the guide groove 202 and push it upward so that the easy-cut disc 203 can push the guide block 204 into the guide groove 202 and drive the riser sleeve body 1 into the bottom of the riser sleeve body 1. Then, reverse the threaded rod 206 and push the insert block 209 into the slot 205 for fixing by rotating the thread. At this time, the spring 210 will also push the push plate 208 with its own elasticity, which can effectively reduce the possibility of loosening and facilitate disassembly and cleaning of the inside of the riser sleeve body 1.
[0025] Example 2, as Figure 1 and Figure 4As shown, a filter assembly 3 is provided on the top of one side of the riser sleeve body 1. The filter assembly 3 includes a groove 301. Threaded holes 302 are provided inside both sides of the groove 301. A filter screen 303 is provided inside the groove 301. Holes 304 are provided inside both sides of the filter screen 303. Bolts 305 are inserted into the holes 304. The bolts 305 pass through the holes 304 and the threaded holes 302 to form a threaded connection.
[0026] The effect achieved in Example 2 is that the filter screen 303 can filter and adsorb impurities and harmful substances in the exhaust gas, thereby improving the cleanliness of the casting environment. At the same time, the filter screen 303 can be disassembled and cleaned by bolts 305, thus improving the overall practicality.
[0027] Working principle: When it is necessary to fix the easy-cut piece 203, the guide block 204 and the guide groove 202 can be used for guidance. At the same time, when the threaded rod 206 is rotated, the insert block 209 can be pushed forward and inserted into the slot 205 for fixation. The spring 210 can also exert a squeezing effect, which can effectively reduce the possibility of loosening. It is also convenient to disassemble and clean the inside of the riser sleeve body 1. When the molten metal inside the riser sleeve body 1 is sprayed upward with the gas, the impurities and harmful substances in the exhaust gas can be removed by installing the filter screen 303, thereby improving the cleanliness of the casting environment.
[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
