Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, specifically to a rapid slag removal mechanism for a casting machine. Background Technology

[0002] A casting machine is an industrial piece of equipment used in foundries to pour molten iron, manganese-silicon alloys, and other materials. Its purpose is to improve the success rate of castings and reduce molten iron waste and burns. In the construction industry, casting machines are used to transport and pour materials such as concrete and mortar to improve construction efficiency and quality.

[0003] In the existing technology, the casting machine pours molten metal into the mold through the pouring cup nozzle. The metal flows along the inner wall of the pouring cup nozzle. When pouring ductile iron, the molten metal easily sticks to the inner wall of the pouring cup nozzle, forming slag. Workers need to use tools to remove the slag from the pouring cup nozzle to avoid slag blockage.

[0004] However, when workers clean the residue from the pouring cup nozzle, they need to stop the operation of the pouring machine and wait for the temperature of the pouring cup nozzle to drop before cleaning can be carried out. This operation is time-consuming and labor-intensive, affecting the production efficiency of the pouring machine. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid slag removal mechanism for a casting machine, so as to solve the technical problem that in the prior art, when workers clean the slag adhering to the pouring cup nozzle, they need to stop the operation of the casting machine and wait for the temperature of the pouring cup nozzle to drop before cleaning, which is time-consuming and labor-intensive and affects the production efficiency of the casting machine.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A rapid slag removal mechanism for a casting machine, comprising:

[0008] A punch cylinder, wherein a mounting head is sleeved and connected to the top end of the punch cylinder, and a sleeve is fixedly connected to the side end of the mounting head;

[0009] An extension rod is slidably connected to the inner wall of the sleeve. The extension rod is supported and connected to positioning bolts on all four sides along the axis. The sleeve is provided with threaded holes on all four sides along the axis, and the positioning bolts are threadedly connected to the inner wall of the threaded holes.

[0010] A connecting column is installed and connected to the side end of an extension rod. A punch rod is fixedly connected to the bottom end of the connecting column. An extension column with a rectangular cross-section is installed and connected to the bottom end of the punch rod. A cleaning column is fixedly connected to the bottom end of the extension column.

[0011] As a further embodiment of this utility model, the cleaning column is in the shape of a twisted rope.

[0012] As a further embodiment of this utility model: a clamping plate is fixedly connected to the side end of the extension rod, and a hinge plate is hinged to the clamping plate. The two ends of the connecting column are respectively abutted and connected to the clamping plate and the hinge plate.

[0013] As a further embodiment of this utility model: a hook is fixedly connected to the side end of the hinge plate, and a bolt-type clamp is fixedly connected to the side end of the extension rod, with the bolt-type clamp and the hook being abutted together.

[0014] As a further embodiment of this utility model, a pull ring is fixedly connected to the top of the connecting column.

[0015] As a further embodiment of this utility model: a horizontal clamp is fixedly connected to the side end of the sleeve, and a circular hole is opened on the side end of the extension rod, with the side end of the horizontal clamp abutting against the inner wall of the circular hole.

[0016] As a further embodiment of this utility model: a limiting plate is fixedly connected to the side end of the mounting head, and an alignment plate is fixedly connected to the top side end of the punch cylinder. The alignment plate has a threaded hole, and a fixing bolt is threadedly connected to the inner wall of the threaded hole. The fixing bolt is abutted against the top end of the slide groove.

[0017] As a further embodiment of this utility model: the limiting plate has a sliding groove with an arc-shaped axis, and the inner wall of the sliding groove is slidably connected to the fixing bolt.

[0018] As a further embodiment of this utility model: an accumulator for assisting the punch cylinder is fixedly connected to the side end of the punch cylinder.

[0019] As a further embodiment of this utility model: an oil storage cylinder is fixedly connected to the top of the accumulator, and the oil storage cylinder is interconnected with the thrust rod cylinder.

[0020] The beneficial effects of this utility model are:

[0021] 1. When there is residue adhering to the inner wall of the pouring cup nozzle, the hydraulic cylinder of the punch rod operates, driving the installation head downward. The installation head drives the extension rod downward through the sleeve, and the extension rod drives the punch rod downward through the connecting column. The punch rod drives the extension column aligned with the pouring cup nozzle downward, and the extension column drives the cleaning column to insert into the pouring cup nozzle. The cleaning column removes the residue adhering to the inner wall of the pouring cup nozzle and then discharges the residue from the bottom of the pouring cup nozzle. The cleaning column automatically removes the residue adhering to the inner wall of the pouring cup nozzle, avoiding the need for workers to interrupt the pouring machine for cooling during cleaning. At the same time, it saves labor costs and improves the working efficiency of the pouring machine.

[0022] 2. When the cleaning column is running for a long time, wear will occur. Workers will remove the extension column from the punch rod and then replace the cleaning column, thus avoiding the need to replace the punch rod. The cleaning column is extended by the extension column, preventing the punch rod from coming into contact with the slag when cleaning. The slag is hot, so this prevents the slag from wearing down the punch rod, thus protecting the punch rod and extending its service life. When the extension rod is inserted into the sleeve for installation, the positioning bolt is rotated and threaded into the threaded hole. The positioning bolt passes through the threaded hole and supports the extension rod around its perimeter. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1-6 As shown, a rapid slag removal mechanism for a casting machine includes: a punch cylinder 3, an extension rod 6, and a connecting column 12.

[0033] A mounting head 18 is sleeved at the top of the punch cylinder 3. A sleeve 2 is fixedly connected to the side of the mounting head 18. An extension rod 6 is slidably connected to the inner wall of the sleeve 2. Positioning bolts 8 are respectively abutted and connected to the extension rod 6 around its axial direction. Threaded holes are opened around the sleeve 2 around its axial direction. The positioning bolts 8 are threadedly connected to the inner wall of the threaded holes. A connecting column 12 is installed and connected to the side of the extension rod 6. A punch 1 is fixedly connected to the bottom of the connecting column 12. An extension column 15 with a rectangular cross-section is installed and connected to the bottom of the punch 1. A cleaning column 16 is fixedly connected to the bottom of the extension column 15. When there is residue on the inner wall of the pouring cup nozzle, the punch cylinder 3 operates. The installation head 18 is moved downwards, and the installation head 18 moves the extension rod 6 downwards through the sleeve 2. The extension rod 6 moves the punch rod 1 downwards through the connecting column 12. The punch rod 1 moves the extension column 15, which is aligned with the pouring cup nozzle, downwards. The extension column 15 moves the cleaning column 16 into the pouring cup nozzle. The cleaning column 16 removes the residue from the inner wall of the pouring cup nozzle and then discharges the residue from the bottom of the pouring cup nozzle. The cleaning column 16 automatically removes the residue from the inner wall of the pouring cup nozzle, avoiding the need for workers to interrupt the pouring machine for cooling during cleaning. At the same time, it saves labor costs and improves the working efficiency of the pouring machine.

[0034] When the cleaning column 16 is running for a long time, wear will occur. Workers will remove the extension column 15 from the punch rod 1 and then replace the cleaning column 16, thus avoiding the need to replace the punch rod 1. The cleaning column 16 is extended by the extension column 15, which prevents the punch rod 1 from coming into contact with the sticky residue when cleaning the residue. The sticky residue is hot, so this prevents the residue from causing wear to the punch rod 1, thus protecting the punch rod 1 and extending the service life of the extension rod 6. When the extension rod 6 is inserted into the sleeve 2 for installation, the positioning bolt 8 is rotated and threaded into the threaded hole. The positioning bolt 8 passes through the threaded hole and supports the extension rod 6 from all sides.

[0035] In some specific implementations, the cleaning column 16 is twisted in shape. When the cleaning column 16 removes the residue from the inner wall of the pouring cup nozzle, the shape of the cleaning column 16 ensures that the residue falls onto the cleaning column 16. During the cleaning process, the cleaning column 16 carries the residue along with it, thereby preventing the residue from remaining between the cleaning column 16 and the inner wall of the pouring cup nozzle.

[0036] In some specific implementations, a clamping plate 11 is fixedly connected to the side end of the extension rod 6, and a hinge plate 13 is hinged to the clamping plate 11. The two ends of the connecting column 12 are respectively abutted against the clamping plate 11 and the hinge plate 13. A hook 14 is fixedly connected to the side end of the hinge plate 13. A bolt-type clamp 9 is fixedly connected to the side end of the extension rod 6. The bolt-type clamp 9 is abutted against the hook 14. A pull ring 10 is fixedly connected to the top of the connecting column 12. When the punch rod 1 is installed on the extension rod 6, a crane is used to hang the pull ring 10. Then, the crane lifts the pull ring 10 and places the connecting column 12 at the clamping plate 11. The hinge plate 13 is rotated, and the hinge plate 13 and the clamping plate 11 abut against the two ends of the connecting column 12. Then, the side end of the bolt-type clamp 9 hangs on the hook 14, thereby pulling the hinge plate 13 to abut against the side end of the connecting column 12.

[0037] In some specific implementations, a horizontal clamp 7 is fixedly connected to the side end of the sleeve 2, and a round hole is opened on the side end of the extension rod 6. The side end of the horizontal clamp 7 is abutted against the inner wall of the round hole. When the extension rod 6 is installed in the sleeve 2, the side end of the horizontal clamp 7 is inserted into the round hole. The side end of the horizontal clamp 7 and the inner wall of the round hole further abut against and limit the extension rod 6, thereby ensuring the stability of the extension rod 6 fixed in the sleeve 2.

[0038] In some specific implementations, a limiting plate 19 is fixedly connected to the side end of the mounting head 18, and an alignment plate 22 is fixedly connected to the top side end of the punch cylinder 3. The alignment plate 22 has a threaded hole, and a fixing bolt 21 is threadedly connected to the inner wall of the threaded hole. The fixing bolt 21 is abutted against the top end of the slide groove 20. The limiting plate 19 has a slide groove 20 with an arc-shaped axis. The inner wall of the slide groove 20 is slidably connected to the fixing bolt 21. When the mounting head 18 is sleeved on the top output end of the punch cylinder 3, the limiting plate 19 and the alignment plate 22 fixed to the side end of the mounting head 18 are aligned. The fixing bolt 21 is threaded through the slide groove 20 and threaded into the threaded hole. Then, the sleeve 2 is finely adjusted by rotating the mounting head 18. Then, the fixing bolt 21 is rotated to abut against the top end of the limiting plate 19, thereby limiting and fixing the limiting plate 19, and thus limiting and fixing the mounting head 18.

[0039] In some specific implementations, an accumulator 5 for assisting the punch cylinder 3 is fixedly connected to the side end of the punch cylinder 3. An oil storage cylinder 4 is fixedly connected to the top of the accumulator 5. The oil storage cylinder 4 is interconnected with the punch cylinder 3. When the punch cylinder 3 needs to run, the accumulator 5 can control the hydraulic oil stored in the oil storage cylinder 4 to flow into the punch cylinder 3. When the punch cylinder 3 runs, the hydraulic oil in the oil storage cylinder 4 can provide assistance to the output end of the punch cylinder 3, thereby enabling the punch 1 to move vertically downward faster. When the punch cylinder 3 malfunctions or loses power, the accumulator 5 can continue to drive the punch cylinder 3 to run by controlling the hydraulic oil stored in the oil storage cylinder 4. When the output end of the punch cylinder 3 is reset, the accumulator 5 can buffer the punch cylinder 3 by controlling the hydraulic oil in the oil storage cylinder 4.

[0040] The foregoing has described several embodiments of this utility model in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
