Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to an anti-splashing device for casting pouring gates. Background Technology

[0002] Casting is the process of injecting prepared casting materials into a mold and allowing them to solidify to obtain a product similar to the mold cavity. The casting materials can be monomers, slurries that have undergone preliminary polymerization or condensation, or liquids of polymers and monomers. In recent years, several new casting methods have emerged based on traditional casting, including insert casting, centrifugal casting, cast casting, slush molding, and rotational molding. During the casting process, splashing often occurs at the gating gate due to the impact force or unstable fluidity of the high-temperature molten metal. The splashed slag easily solidifies on the surface of the structure after cooling, making it difficult to clean. This not only wastes material but may also endanger operator safety and pollute the working environment.

[0003] For example, the patent with authorization announcement number CN221246919U describes a splash-proof casting structure. However, the structure only installs guide slides on both sides of the casting port. The protection range of the guide slides is limited, resulting in poor protection around the casting port. In addition, there is a certain distance between the casting port and the mold, which may increase the probability of splashing of the casting liquid.

[0004] Based on this, a splash prevention device for casting gates is now provided, which can eliminate the drawbacks of existing technical solutions. Utility Model Content

[0005] The purpose of this invention is to provide an anti-splashing device for casting gates, in order to solve the problems in the prior art where the protection around the casting gate is poor and the distance between the casting gate and the mold increases the probability of splashing of the casting liquid.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A splash-proof device for a casting pouring gate includes a top plate disposed above a casting container, a pouring gate being provided on one side of the casting container, the top plate being connected to the casting container via an adjustment mechanism, the adjustment mechanism being used to adjust the position of the casting container to bring it closer to the object to be cast, and a protective mechanism for preventing casting liquid from splashing being provided on one side of the pouring gate.

[0008] The adjustment mechanism includes support frames symmetrically installed at the bottom of the top plate. The surface of the support frame is provided with a sliding groove, and a slider is slidably arranged inside the sliding groove. An electric push rod is fixedly installed on the top plate. The output end of the electric push rod is fixedly connected to the upper surface of one of the sliders. A casting container is arranged between the two sliders. The casting container is rotatably connected to the slider through a rotating shaft. One end of the rotating shaft passes through the slider and is fixedly connected to the output end of the gearbox. The input end of the gearbox is fixedly connected to the output end of the drive motor.

A rotating rod is rotatably mounted on the top of the bracket, and each rotating rod is fixedly connected to a baffle. A connecting rod is fixedly mounted on the rotating rod, and a funnel is fixedly mounted on the bottom of the connecting rod. The funnel is located inside the baffle, and both the upper and lower sides of the funnel are circular openings. The inner diameter of the circular opening at the top is larger than the width of the casting port. A detachable component for adjusting the size of the circular opening is provided at the bottom of the funnel.

[0010] Preferably, the baffle includes a first blocking layer, a second blocking layer, and a guiding layer. The first blocking layer is fixedly disposed on top of the second blocking layer, and the second blocking layer is fixedly disposed on top of the guiding layer. Both the first blocking layer and the guiding layer are configured as C-shaped structures with openings. The outer diameter of the first blocking layer is larger than the outer diameter of the guiding layer. The bottom end of the second blocking layer is inclined inward. A counterweight is disposed on the outer wall of the guiding layer.

[0011] Preferably, the detachable component includes a mounting block fixedly disposed on the outside of the funnel, and the lower end of the mounting block is threadedly connected to a guide hopper.

[0014] Preferably, pulleys are fixedly installed at the bottom of each support frame.

[0015] Preferably, both the baffle and the funnel are coated with refractory mud.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The anti-splash device for the casting gate uses an adjustment mechanism consisting of an electric push rod, a slider, and a rotating shaft to precisely adjust the height, horizontal position, and tilt angle of the casting container. This ensures accurate alignment between the casting gate and the mold, reducing splashing caused by misalignment. The baffle adopts a composite structure of a first blocking layer, a second blocking layer, and a guiding layer, intercepting splashed molten metal in layers.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In this embodiment, as Figures 1-7 As shown, a splash-proof device for a casting pouring gate includes a top plate 102 disposed above a casting container 101. The top of the casting container 101 is provided with a cover plate. The device may have a controller (not shown) on one side of a support frame 201. The controller is electrically connected to a drive motor and an electric push rod 204 to facilitate the output of commands. A pouring gate 103 is provided on one side of the casting container 101. The top plate 102 is connected to the casting container 101 through an adjustment mechanism 200. The adjustment mechanism 200 is used to adjust the position of the casting container 101 so that it is close to the object to be cast. The electric adjustment realizes the fine adjustment of the casting position and angle, improving the casting accuracy. A protective mechanism 300 for preventing casting liquid from splashing is provided on one side of the pouring gate 103. Through the synergistic effect of the multi-layer baffle 303 and the adjustable funnel 304, splashing and waste are significantly reduced.

[0028] The adjustment mechanism 200 includes support frames 201 symmetrically installed at the bottom of the top plate 102. A groove 202 is formed on the surface of the support frame 201, and a slider 203 is slidably disposed inside the groove 202. An electric push rod 204 is fixedly installed on the top plate 102. The installation position and number of electric push rods 204 can be selected according to actual environmental requirements to avoid uneven force distribution when the casting container 101 is tilted. The electric push rods 204 can be symmetrically arranged. The output end of each electric push rod 204 is fixedly connected to the upper surface of one of the sliders 203, and the electric push rod 204 pushes the slider 203 to slide within the groove 202. The casting container 101 is moved horizontally to shorten the distance between the casting port 103 and the object to be cast. The casting container 101 is set between two sliders 203. The casting container 101 is rotatably connected to the sliders 203 through a rotating shaft 205. One end of the rotating shaft 205 passes through the slider 203 and is fixedly connected to the output end of the gearbox 206. The input end of the gearbox 206 is fixedly connected to the output end of the drive motor. The drive motor drives the rotating shaft 205 to rotate through the gearbox 206, thereby adjusting the tilt angle of the casting container 101 and controlling the speed and direction of the casting liquid flowing out of the casting port 103.

[0029] Among them, such as Figures 3-7As shown, the protective mechanism 300 includes supports 301 symmetrically arranged on both sides of the casting port 103, providing stable support for the entire protective mechanism 300. A rotating rod 302 is rotatably mounted on the top of each support 301, and the rotating rod 302 is fixedly connected to a baffle 303. By rotating the rotating rod 302, the angles of the baffle 303 and the funnel 304 can be adjusted to adapt to different casting requirements. A connecting rod is fixedly mounted on the rotating rod 302, and a funnel 304 is fixedly mounted at the bottom of the connecting rod. The funnel 304 is positioned within the baffle 303. Inside the funnel 304, both the top and bottom sides are set with circular openings. The inner diameter of the circular opening at the top is larger than the width of the casting port 103, ensuring that all the casting liquid enters the funnel 304. The detachable guide hopper 306 adjusts the opening size through a threaded connection to adapt to different flow requirements, making it easy to guide the casting liquid into molds of different sizes and reduce waste. The bottom of the funnel 304 is equipped with a detachable component for adjusting the size of the circular opening, which can flexibly cope with different mold sizes and flow requirements, significantly reducing material waste.

[0030] Among them, such as Figure 3 and Figure 6 As shown, the baffle 303 includes a first blocking layer 3031, a second blocking layer 3032, and a guiding layer 3033. The first blocking layer 3031 is fixedly disposed on top of the second blocking layer 3032, expanding the blocking range and intercepting large splashed metal particles. The second blocking layer 3032 is fixedly disposed on top of the guiding layer 3033, and its inclined design guides the splashed liquid to the guiding layer 3033. The guiding layer 3033 can be tilted towards the inside of the funnel 304 to avoid liquid waste, or as shown in the figure... As shown, to facilitate subsequent centralized treatment of splashed liquid, both the first blocking layer 3031 and the guiding layer 3033 are configured as C-shaped structures with openings facing the casting port 103. The outer diameter of the first blocking layer 3031 is larger than that of the guiding layer 3033. The bottom end of the second blocking layer 3032 is inclined inward. A counterweight 3034 is provided on the outer wall of the guiding layer 3033. The counterweight 3034 maintains balance, so that the baffle 303 can maintain a vertical guiding state and ensure that the baffle 303 stably covers the casting port 103.

[0031] Among them, such as Figure 5 and Figure 7As shown, the detachable component includes a mounting block 305 fixedly mounted on the outside of the funnel 304. The lower end of the mounting block 305 is threadedly connected to a guide hopper 306. The guide hopper 306 and the mounting block 305 are made of high-temperature resistant materials, such as ceramic-coated metal, to withstand the high temperature of the molten metal. An anti-stick coating is added to the inner wall of the guide hopper 306 to reduce the adhesion of molten metal. The guide hopper 306 is connected to the mounting block 305 by threads, which facilitates the replacement of guide hoppers 306 of different diameters or materials according to casting requirements, adapting to the flow control of different casting liquids. High-temperature resistant gaskets can be added at the threads to prevent liquid leakage. The mounting block 305 is fixed to the outside of the funnel 304. The use of heat-resistant materials makes the threaded structure less prone to loosening in high-temperature environments, ensuring the stability of the guide hopper 306 during the casting process. A suitable guide hopper 306 can be pre-installed before casting. If adjustments are needed during the process, it can be quickly disassembled and replaced without interrupting the operation.

[0032] Among them, such as Figures 1-5 As shown, the surface of the top plate 102 is provided with a notch 104 for the casting container 101 and the baffle 303 to pass through. The notch 104 provides vertical movement space for the casting container 101 and the baffle 303, so that they are not obstructed by the top plate 102 when they are raised, lowered or tilted. When the electric push rod 204 pushes the slider 203 or the drive motor rotates the casting container 101 through the rotating shaft 205, the notch 104 allows the casting port 103 and the protective mechanism 300 to flexibly adjust their positions to adapt to different casting angle and height requirements. The outline of the notch 104 matches the outer diameter of the baffle 303 and the casting container 101.

[0033] Among them, such as Figures 2-5 As shown, several telescopic rods 207 are also fixedly installed on the top plate 102. The telescopic ends of the telescopic rods 207 are all fixedly connected to the slider 203. The telescopic rods 207 help stabilize the movement of the slider 203 and prevent it from shaking.

[0034] Among them, such as Figure 2 As shown, pulleys 208 are fixedly installed at the bottom of the support frame 201. The pulleys 208 are self-locking casters, which are easy to move and make the device suitable for different work positions.

[0035] Among them, such as Figures 3-7 As shown, both the baffle 303 and the funnel 304 are coated with refractory mud. The refractory mud coating is a silicon carbide ceramic coating with a thickness of 2-5 mm and a temperature resistance of ≥1600℃. It can withstand high-temperature casting liquid and extend its service life.

[0036] In use, the electric push rod 204 pushes the slider 203 to slide in the groove 202, causing the casting container 101 to move horizontally, so that its casting port 103 is precisely aligned with the object to be cast. The drive motor and gearbox 206 drive the casting container 101 to rotate through the rotating shaft 205, adjusting the casting angle to ensure that the casting liquid flows into the mold at the best angle, reducing impact and splashing. The telescopic rod 207 helps to stabilize the movement of the slider 203 and prevent shaking. The pulley 208 facilitates the movement of the entire device to adapt to the needs of different work stations. The baffle 303 can be rotated and adjusted in position through the rotating rod 302, and is simultaneously adjusted to the area around the casting port 103. Its multi-layer structure forms a stepped protection. The top opening of the funnel 304 is larger than the casting port 103, and the bottom outlet size is adjusted through the detachable guide hopper 306 to guide the liquid to flow into the mold in a concentrated manner, reducing spillage.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
