Description

Technical Field

[0001] This utility model relates to the field of gravity casting machine technology, and in particular to a smoke exhaust device for a gravity casting machine and a gravity casting machine. Background Technology

[0002] A gravity casting machine is a piece of equipment used for metal casting. It mainly uses gravity to pour molten metal from a ladle into a mold to form a metal casting.

[0003] Gravity casting machines include a mold opening and closing assembly and a fume extraction assembly. The mold opening and closing assembly is telescopic and is responsible for opening or closing the mold, while the fume extraction assembly removes fumes generated during the casting process. The fume extraction assembly is usually located on the mold opening and closing assembly, and the mold opening and closing assembly drives the fume extraction assembly to move synchronously when controlling the mold to open or close.

[0004] However, placing the smoke removal component on the opening and closing mold component increases the load on the opening and closing mold component, making the smoke removal component prone to shaking; at the same time, because the smoke removal component is too close to the mold, the airflow is easily blocked by the mold, affecting the smoke removal effect. Utility Model Content

[0005] (I) The problem to be solved by this utility model is that the smoke removal component is set on the opening and closing mold component, which results in a large load on the opening and closing mold component. At the same time, the smoke removal component is too close to the mold, which affects the smoke removal effect.

[0038] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] like Figure 1 As shown, one embodiment of this utility model provides a smoke exhaust device for a gravity casting machine. The gravity casting machine includes a frame 11 and a mold opening and closing mechanism 12 disposed on the frame 11. The smoke exhaust device for the gravity casting machine includes an air blowing mechanism 21 and a ventilation mechanism 22. Both the air blowing mechanism 21 and the ventilation mechanism 22 are fixed on the frame 11 and located beside the mold opening and closing mechanism 12. The air blowing mechanism 21 is used to blow away the smoke generated during casting, and the ventilation mechanism 22 is used to extract the smoke generated during casting.

[0040] In this embodiment, the gravity casting machine includes a frame 11 and a mold opening and closing mechanism 12. The frame 11 is placed on the ground, and the mold opening and closing mechanism 12 consists of two opposing hydraulic cylinders. The two cylinders are used to control the opening and closing of the mold. When the mold on the two cylinders is closed, the molten metal in the ladle can be poured into the mold to complete the casting. Furthermore, the fume extraction device of the gravity casting machine provided in this embodiment includes a blowing mechanism 21 and a suction mechanism 22. During casting, molten metal is poured into the mold, generating fumes. The blowing mechanism 21 is used to blow away the generated fumes, while the suction mechanism 22 can form a negative pressure zone to extract the generated fumes. Preferably, the blowing mechanism 21 and the suction mechanism 22 can be arranged opposite to each other, thereby forming a fume guide between the blowing mechanism 21 and the suction mechanism 22 to improve the fume removal effect. Both the blowing mechanism 21 and the exhaust mechanism 22 are fixed on the frame 11. Furthermore, the blowing mechanism 21 and the exhaust mechanism 22 are located on the side of the mold opening and closing mechanism 12. That is, there is no connection between the blowing mechanism 21 and the exhaust mechanism 22 and the mold opening and closing mechanism 12. When the mold opening and closing mechanism 12 is activated, the blowing mechanism 21 and the exhaust mechanism 22 will not activate synchronously with the mold opening and closing mechanism 12.

[0041] The smoke exhaust device of the gravity casting machine provided in this embodiment fixes the air blowing mechanism 21 and the exhaust mechanism 22 on the frame 11. The air blowing mechanism 21 and the exhaust mechanism 22 do not move synchronously with the mold opening and closing mechanism 12. Compared with the prior art, the air blowing mechanism 21 and the exhaust mechanism 22 have stronger stability and better smoke removal effect.

[0042] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the blowing mechanism 21 includes a bracket 211 and a blowing pipe 212; the bracket 211 is fixed on the frame 11; one end of the blowing pipe 212 is located on the frame 11, and the position of the blowing pipe 212 on the frame 11 is adjustable, and the other end can be connected to a first power source, which is used to provide power for blowing the flue gas through the blowing pipe 212.

[0043] In this embodiment, the air blowing mechanism 21 includes a bracket 211 and an air blowing pipe 212. The bracket 211 can be fixed to the frame 11 by welding, riveting, or screwing. During assembly, one end of the air blowing pipe 212 is connected to a first power source, and the other end is set on the frame 11. The first power source can be a fan or a compressed gas source, etc. The position of the end of the air blowing pipe 212 away from the first power source on the frame 11 is adjustable, so that a good smoke removal effect can be achieved under molds of different sizes. Optionally, the bracket 211 is vertically arranged, and the vertical position of the end of the air blowing pipe 212 away from the first power source on the frame 11 is adjustable. It should be noted that the vertical direction is... Figure 1 The up and down directions are shown in the image.

[0044] Optionally, in this embodiment, the blowing mechanism 21 may also include a nozzle, which may be a high-pressure nozzle. The nozzle may be mounted on the bracket 211 via a universal joint to facilitate the adjustment of the nozzle's orientation, thereby improving the smoke removal effect of the blowing mechanism 21.

[0045] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the end of the air blowing pipe 212 away from the first power source is slidably mounted on the bracket 211.

[0046] In this embodiment, the end of the air blowing pipe 212 furthest from the first power source is slidably mounted on the bracket 211, thereby allowing for adjustable positioning of this end on the bracket 211. This slidable mounting of the air blowing pipe 212 to the bracket 211 provides more flexible placement options, enabling better smoke removal performance even with molds of different sizes, thus enhancing its practicality.

[0047] It is understood that, in this embodiment, multiple mounting points can also be provided on the frame 11 for mounting the end of the air blowing pipe 212 away from the first power source. This also achieves the purpose of adjustable positioning of the end of the air blowing pipe 212 away from the first power source on the frame 11. The mounting points can be holes or slots, etc.

[0048] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the air blowing mechanism 21 also includes a clamp; the end of the air blowing pipe 212 away from the first power source is connected to the clamp and is slidably mounted on the bracket 211 through the clamp.

[0049] The aforementioned support 211 has a columnar structure and can be made of metal tubing or structural steel. The end of the air blowing pipe 212 furthest from the first power source is connected to a clamp and slidably mounted on the support 211 via the clamp. By tightening or loosening the clamp, the position of the end of the air blowing pipe 212 furthest from the first power source can be adjusted. Using a clamp to achieve this slidable mounting of the end of the air blowing pipe 212 furthest from the first power source on the support 211 is simple in structure, low in cost, and convenient for inspection and maintenance.

[0050] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the exhaust mechanism 22 includes a smoke hood 221 and a mounting component; the mounting component is fixed on the frame 11; the smoke hood 221 is mounted on the mounting component, and the position of the smoke hood 221 on the mounting component is adjustable; the smoke hood 221 can also be connected to a second power source, which is used to create a negative pressure inside the smoke hood 221.

[0051] In this embodiment, the exhaust mechanism 22 includes a smoke hood 221 and a mounting component. The smoke hood 221 has a semi-open structure, which provides good smoke collection and reduces smoke escape. The smoke hood 221 has an exhaust side and an intake side, with the intake side facing the mold and the exhaust side connected to a second power source, which can be a fan, to create negative pressure inside the smoke hood 221, thereby drawing away the smoke generated during casting. The smoke hood 221 is mounted on the frame 11 via a mounting component fixed to the frame 11, and the position of the smoke hood 221 on the mounting component is adjustable, thus achieving better smoke removal effect for molds of different sizes.

[0052] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the smoke hood 221 is slidably mounted on the mounting component.

[0053] Preferably, in this embodiment, the smoke hood 221 is slidably mounted on the mounting component to facilitate adjustment by the operator. The sliding direction of the smoke hood 221 is left-right, allowing it to be moved closer to or further away from the mold.

[0054] It is understood that, in this embodiment, multiple mounting points for the smoke hood 221 can also be provided on the mounting component, which can also achieve the purpose of adjustable positioning of the smoke hood 221 on the mounting component in this embodiment. In this case, the mounting component can be a mounting plate or a support frame, etc.

[0055] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the mounting component is a slide rail 222, and the smoke hood 221 is mounted on the slide rail 222 and can slide along the extension direction of the slide rail 222.

[0056] Preferably, in this embodiment, the mounting component is a slide rail 222, which has a simple structure and low cost. The smoke hood 221 can be slidably mounted on the slide rail 222 via a sliding block or other structure. The extension direction of the slide rail 222 is the same as the extension direction of the mold opening and closing mechanism 12, so that the smoke hood 221 can move towards or away from the mold, thereby improving the smoke exhaust effect.

[0057] It is understood that in this embodiment, the mounting component can also adopt a rod-shaped structure. By setting through holes on the smoke hood 221, the purpose of the smoke hood 221 sliding on the mounting component in this embodiment can also be achieved.

[0058] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the exhaust mechanism 22 also includes a limiting component, which is used to fix the smoke hood 221 when it slides to a preset position.

[0059] As mentioned above, the smoke hood 221 can slide on the mounting component. After the position of the smoke hood 221 is adjusted into place, in order to ensure the stability of the smoke hood 221 and avoid affecting the smoke hood 221's ability to draw away the smoke, the exhaust mechanism 22 also includes a limiting component for fixing the smoke hood 221.

[0060] The smoke exhaust device for the gravity casting machine provided in this embodiment of the utility model, such as Figure 1 As shown, the limiting component includes a limiting pin; along the sliding direction of the smoke hood 221, a plurality of first limiting holes are provided at intervals on the frame 11, and a second limiting hole is provided on the smoke hood 221; in use, the smoke hood 221 is slid to a preset position, and the first limiting hole and the human limiting hole are made coaxial, and the limiting pin is inserted into the first limiting hole and the second limiting hole to fix the smoke hood 221.

[0061] Another embodiment of this utility model provides a gravity casting machine, including the smoke exhaust device of the gravity casting machine described in any of the above embodiments.

[0062] In this embodiment, the gravity casting machine includes all the technical effects of the smoke exhaust device of the gravity casting machine described above, so it will not be repeated here.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
