Description

Technical Field

[0001] This utility model relates to the field of casting device technology, and in particular to a splash-proof casting device for water meter casting. Background Technology

[0002] Water meters, as key instruments for measuring water flow, are widely used in daily life and industrial production. With socio-economic development and increased emphasis on water resource management, the demand for and quality requirements of water meters are growing daily. The casting process is a crucial step in water meter production, directly affecting the meter's performance, accuracy, and lifespan. Currently, water meter casting primarily employs sand casting and metal mold casting processes, and regardless of the process, the pouring process is the core step determining the quality of the casting.

[0003] In traditional water meter casting processes, there is a lack of anti-splash protection measures. When high-temperature molten metal is poured from the ladle into the mold cavity, splashing is very likely to occur due to factors such as the drop between the ladle outlet and the mold inlet, the flow rate of the molten metal, and the shape of the gate. The splashing high-temperature molten metal poses a serious threat to the personal safety of operators and can easily cause burns and other accidents. Utility Model Content

[0004] To address the technical problem of the lack of anti-splash protection measures in the traditional water meter casting process, this utility model provides an anti-splash casting device for water meter casting.

[0005] The technical solution adopted by this utility model is: a splash-proof casting device for water meter casting, including a frame, a storage cylinder on the frame, a discharge pipe fixedly connected to the bottom of the storage cylinder, a valve installed in the discharge pipe, a spiral tube fixedly connected to the bottom of the discharge pipe, the inner cavity of the spiral tube adopts a variable diameter spiral structure, the inner diameter of the spiral tube gradually decreases from the end connected to the discharge pipe to the outer end, forming a contraction channel, and a splash-proof component is provided on the outside of the frame.

[0006] In one embodiment, casters are fixedly installed around the bottom of the frame.

[0007] In one embodiment, hydraulic cylinders are fixedly connected to the outer two sides of the frame, and a connecting rod is fixedly connected to the output end of the hydraulic cylinder. One end of the connecting rod is fixedly connected to the storage cylinder.

[0008] In one embodiment, a guide rod is fixedly connected to the frame, and the guide rod passes through the fixed plate.

[0009] In one embodiment, the anti-splash assembly is an anti-splash cloth fixedly connected to both sides of the frame, and an electric push rod is fixedly connected to the frame, with the output end of the electric push rod fixedly connected to the anti-splash cloth.

[0010] In one embodiment, the splashproof cloth is externally fixed to multiple sets of fixing frames.

[0011] In one embodiment, magnets are fixedly connected to the end faces of the two opposing fixed frames.

[0012] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, after storing the molten metal in the storage cylinder, the molten metal can be injected into the water meter mold through the spiral tube for pouring. During the pouring process, the anti-splash component can protect the workers from being burned by the splashed molten metal, thus ensuring the safety of the workers. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0021] To address the problems existing in the background art, this application proposes the following technical solution: a splash-proof casting device for water meter casting, comprising a frame 1, universal wheels 3 fixedly installed around the bottom of the frame 1, hydraulic cylinders 7 fixedly connected to the outer sides of the frame 1, a connecting rod 4 fixedly connected to the output end of the hydraulic cylinder 7, one end of the connecting rod 4 fixedly connected to the storage cylinder 2, a guide rod 6 fixedly connected to the frame 1, the guide rod 6 penetrating the fixing plate 5, and the hydraulic cylinder 7 used to adjust the height of the storage cylinder 2.

[0022] In a further design, a storage cylinder 2 is provided on the frame 1. A discharge pipe 8 is fixedly connected to the bottom of the storage cylinder 2. A valve 9 is installed in the discharge pipe 8. A spiral tube 10 is fixedly connected to the bottom of the discharge pipe 8. The inner cavity of the spiral tube 10 adopts a variable diameter spiral structure. The inner diameter of the spiral tube 10 gradually decreases from the end connected to the discharge pipe 8 to the outer end, forming a contraction channel. This can increase the flow rate of the molten metal without increasing the driving pressure. An anti-splash component is provided on the outside of the frame 1.

[0023] Additionally, as another embodiment, spiral guide vanes can be provided inside the spiral tube 10. These vanes are spirally distributed along the inner wall of the guide tube. When the liquid metal flows through the guide tube, the liquid metal will rotate under the action of the spiral guide vanes. This rotational motion not only makes the flow velocity distribution of the liquid metal on the cross-section more uniform, but also increases the friction between the liquid metal and the inner wall of the guide tube, thereby further slowing down the flow velocity of the liquid metal, reducing its impact force, and effectively reducing splashing of the liquid metal. The guide tube is made of high-temperature resistant and corrosion-resistant stainless steel to ensure its long-term stable operation in high-temperature and harsh working environments.

[0024] In a further design, the anti-splash assembly consists of anti-splash fabric 12 fixedly connected to both sides of the frame 1. An electric actuator 11 is fixedly connected to the frame 1, and the output end of the electric actuator 11 is fixedly connected to the anti-splash fabric 12. The anti-splash fabric 12 is made of a high-temperature resistant, transparent special glass fiber reinforced composite material. This material not only has excellent high-temperature resistance, capable of withstanding the radiant heat of high-temperature liquid metal, but also possesses high strength and toughness, making it less prone to breakage.

[0025] In addition, multiple sets of fixing frames 13 are fixedly connected to the outside of the splashproof cloth 12. Magnets are fixedly connected to the end faces of two opposing fixing frames 13. With the setting of the magnets, after the casting is completed, the electric push rod 11 is activated to pull up the splashproof cloth 12, and the two adjacent fixing frames 13 will attract and fix each other, thereby folding and storing the splashproof cloth 12.

[0026] The specific operation method of this utility model is as follows:

[0027] High-temperature molten metal is stored in storage cylinder 2. Then, the frame 1 is pushed to move storage cylinder 2 until the spiral tube 10 aligns with the water meter mold. Next, hydraulic cylinder 7 is activated to adjust the height of storage cylinder 2, connecting the spiral tube 10 to the mold. Then, electric push rod 11 is activated to move anti-splash cloth 12 downwards, surrounding storage cylinder 2 to prevent workers from being scalded by splashing liquid during casting. The spiral tube 10 employs a special variable-diameter spiral structure design, which can increase the flow rate of the molten metal without increasing the driving pressure. After casting is complete, electric push rod 11 is activated to pull up the anti-splash cloth 12.

[0028] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
