Description

Technical Field

[0001] This utility model relates to the field of casting application technology, and in particular to a casting gate anti-splash buffer baffle device. Background Technology

[0002] During the casting process, when molten metal is poured into the mold cavity through the gating gate, splashing often occurs due to the high flow rate and impact force of the molten metal. This splashing not only wastes metal materials and increases production costs, but also poses a threat to the personal safety of operators. Furthermore, after cooling, the splashed molten metal adheres to equipment and the work area, affecting the normal operation of equipment and the cleanliness of the working environment.

[0003] Existing measures to prevent molten metal splashing are not ideal. For example, simple baffle structures cannot effectively buffer the impact of molten metal and cannot effectively suppress splashing; some devices with buffering functions are complex in structure, inconvenient to install and maintain, and costly. Therefore, this utility model proposes a casting gate anti-splash buffer baffle device. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a casting gate anti-splash buffer baffle device to solve the problems of serious metal splashing during casting process, poor effect of existing anti-splash devices, and complex structure in the prior art.

[0005] To solve the above technical problems, the present invention provides a technical solution: a casting gate anti-splash buffer baffle device, including a fixed frame for connecting with casting equipment, wherein a protective baffle is movably connected to the inner wall of the fixed frame near the top position through a buffer assembly, and the buffer assembly realizes the buffering movement of the protective baffle on the fixed frame.

[0006] The protective baffle is arc-shaped with its concave surface facing the gate direction to disperse the impact of molten metal and reduce splashing. The inner wall of the fixing frame is rotatably adjustable near the bottom and has a matching component supporting the bottom of the protective baffle.

[0007] The present invention is further configured such that the fixing frame is U-shaped and has a plurality of mounting holes evenly distributed at its bottom.

[0008] The above technical solution facilitates the use of bolts to install the fixing frame on the casting equipment.

[0009] The present invention is further configured such that the protective baffle is in the shape of a semi-open horn, and its outlet end is connected to a funnel end in an arc shape.

[0010] The above technical solution utilizes a semi-open funnel-shaped design to block the poured molten metal from both sides, preventing splashing and ensuring a stable downward flow of the molten metal. Finally, the funnel end guides the molten metal into the casting mold.

[0011] The present invention is further configured such that: the buffer assembly includes a slide rod installed inside the movable groove; the outer wall of the slide rod is wrapped with a spring and slidably connected to a slider; the two sides of the protective baffle are symmetrically fixedly connected with connecting shafts, and the two connecting shafts are rotatably connected to the two sliders respectively; the top of the slide rod passes through the top of the fixed frame; the top of the fixed frame is threadedly connected with an adjusting sleeve, and the bottom of the adjusting sleeve abuts against the top of the slider.

[0012] The above technical solution allows the protective baffle to slide on the slide rod and compress the spring when the impact force is applied to the slider. The plastic deformation of the spring can be used to offset the impact force brought by the protective baffle.

[0013] The present invention is further configured such that: the two adjusting sleeves are respectively driven by the rotation of the extension blocks provided on their outer walls, so that their end faces are pressed against the sliders provided and slide on the inner wall of the movable groove.

[0014] The above technical solution facilitates the downward impact of molten metal during casting, which pushes the protective baffle downward, causing the protective baffle to slide and rotate, thus keeping the outlet stable.

[0015] The present invention is further configured such that: the mating assembly includes an auxiliary rod supported at the bottom of the protective baffle, both ends of the auxiliary rod are fixedly connected to an adjusting rod, the outer walls of the two adjusting rods are locked with a stabilizing frame by bolts, the end faces of the two stabilizing frames are respectively bolted to the inner wall of the fixed frame, and an anti-slip pad is provided at the connection with the fixed frame.

[0016] The above technical solution uses bolts to fix the stabilizer frame and maintains stability with the help of anti-slip pads to prevent rotation during operation. In addition, the adjustment rod drives the auxiliary rod with an arc-shaped end face to fix the bottom of the protective baffle in position, so as to accurately pour the molten metal into the casting mold.

[0017] The present invention is further configured such that: the inner walls of both stabilizers are provided with sliding grooves to allow for sliding adjustment of the bolts connecting the adjusting rods; and the two side walls of both stabilizers are fixedly connected with limiting edges.

[0018] The above technical solution allows the adjusting rod to slide within the groove of the stabilizer frame during adjustment, thereby enabling the adjustment of the angle and position of the protective baffle. Furthermore, the adjusting rod is limited and stabilized by the limiting edge.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. The casting gate anti-splash buffer baffle device proposed in this utility model can effectively disperse and absorb the impact force of molten metal by setting an arc-shaped buffer baffle and buffer components, which greatly reduces the splashing of molten metal, improves the utilization rate of metal materials, and reduces production costs.

[0021] 2. The casting gate anti-splash buffer baffle device proposed in this utility model has an adjustable position and angle of buffer baffle, which can adapt to different casting processes and gate positions, thus improving the versatility and practicality of the device.

Detailed Implementation

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] like Figures 1-4 As shown, a casting gate anti-splash buffer baffle device includes a fixed frame 1 for connecting to the casting equipment. The fixed frame 1 is U-shaped, with multiple mounting holes 11 evenly distributed at its bottom to facilitate the installation of the fixed frame 1 on the casting equipment using bolts. A protective baffle 2 is movably connected to the inner wall of the fixed frame 1 near the top via a buffer assembly 3. The buffer assembly 3 enables the protective baffle 2 to buffer on the fixed frame 1. The protective baffle 2 is generally semi-open funnel-shaped, and its outlet end is arc-shaped and connected to a funnel end 21. The semi-open funnel shape can block the poured molten metal from both sides, achieving an anti-splash effect, while ensuring stable downward flow of the molten metal. Finally, the funnel end 21 guides the molten metal into the casting mold. The protective baffle 2 is arc-shaped, with the concave surface facing the gate direction to disperse the impact of the molten metal and reduce splashing.

[0030] like Figure 2 and Figure 3 As shown, the buffer assembly 3 includes a slide rod 31 installed inside the movable groove 12. A spring 32 is wrapped around the outer wall of the slide rod 31, and a slider 33 is slidably connected to it. Connecting shafts 22 are symmetrically fixed to both sides of the protective baffle 2, and the two connecting shafts 22 are rotatably connected to the two sliders 33 respectively. The top of the slide rod 31 penetrates the top of the fixing frame 1. An adjusting sleeve 34 is threadedly connected to the top of the fixing frame 1, and the bottom of the adjusting sleeve 34 abuts against the top of the slider 33, so that when the protective baffle 2 is subjected to impact force on the slider 33, it can slide on the slide rod 31. The spring 32 is compressed, and its plastic deformation characteristics can offset the impact force from the protective baffle 2. The two adjusting sleeves 34 are driven to rotate by the extension blocks 341 on their outer walls, so that their end faces are pressed against the slider 33 and slide on the inner wall of the movable groove 12. The adjusting sleeves 34 can adjust the tilt angle of the protective baffle 2. At the same time, when the molten metal is poured, its downward impact will press the protective baffle 2 downward, causing the protective baffle 2 to drive the slider 33 to slide and rotate, so as to keep the outlet stable.

[0031] like Figure 5As shown, a mating assembly 4 is rotatably and adjustable near the bottom of the inner wall of the fixing frame 1. The mating assembly 4 supports the bottom of the protective baffle 2. The mating assembly 4 includes an auxiliary rod 46 that rests on the bottom of the protective baffle 2. Adjusting rods 45 are fixedly connected to both ends of the auxiliary rod 46. Stabilizing frames 41 are bolted to the outer walls of the two adjusting rods 45. Sliding grooves 43 are provided on the inner walls of the two stabilizing frames 41 to allow sliding adjustment of the bolts connecting the adjusting rods 45. Limiting edges 44 are fixedly connected to both side walls of the two stabilizing frames 41 to facilitate the adjustment of the adjusting rods 45 within the stabilizing frames 41. The slide adjustment is made in the groove 43, so that the angle and position of the protective baffle 2 can be adjusted. Under the action of the limiting edge 44, the adjusting rod 45 can be limited and operated stably. The end faces of the two stabilizing frames 41 are respectively bolted to the inner wall of the fixed frame 1, and the connection with the fixed frame 1 is provided with anti-slip pads 42. The stabilizing frames 41 are fixed with bolts and kept stable under the action of anti-slip pads 42 to prevent rotation during operation. The adjusting rod 45 drives the auxiliary rod 46 with the arc-shaped end face to fix the bottom of the protective baffle 2 in position so as to accurately pour the molten metal into the casting mold.

[0032] In use, molten metal is poured onto the protective baffle 2, and the impact force acts on the protective baffle 2. The protective baffle 2, through its connecting shaft 22, drives the slider 33 to slide on the slide rod 31 and compress the spring 32. The plastic deformation characteristic of the spring 32 can offset the impact force brought by the protective baffle 2. At the same time, the outlet position of the protective baffle 2 is adjusted on the auxiliary rod 46, allowing the molten metal to flow into the casting equipment. In this operation, the position of the slider 33 can be adjusted using the adjusting sleeve 34, thereby adjusting the tilt angle of the protective baffle 2. At the same time, the adjustment rod 45 at the bottom can be adjusted to adjust the position of the funnel end 21 of the protective baffle 2, so as to realize the use of different casting equipment gates.
