Description

Technical Field

[0001] The utility model relates to the technical field of disc casting machines, in particular to a blower used for cleaning the surface of a disc casting mould. Background Art

[0002] During the casting process of the copper mold casting machine, it is inevitable that molten copper will splash onto the mold and then solidify into debris. The splashing debris located on the top frame of the mold gradually accumulates and connects, and will fall into the gap between the ejector rod and the mold during pre-lifting or jacking, resulting in "stuck ejector rod". At this time, if the on-site staff does not discover it in time and continue casting, "top rod" will be generated. "Top rod" is a more harmful accident. The current method to prevent "stuck ejector rod" is to manually go to the disc casting machine and use iron sheets to scrape off the accumulated splashing debris, which is labor-intensive. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a blower for cleaning the surface of a disc casting mold, which solves the problem that splashing debris located on the top frame of the mold gradually accumulates and hooks together and falls into the gap between the ejector rod and the mold during pre-lifting or lifting.

[0004] To achieve the above purpose, the utility model is implemented through the following technical scheme: a purge device for cleaning the surface of a disc casting mold, including an air source, a pipeline, a blowing nozzle, a solenoid valve, an on-site switch, a remote switch, a signal generator and a copper mold, the air source of the purge device is miscellaneous compressed air, the pipeline is a rubber hose, the blowing nozzle is a stainless steel pipe, the solenoid valve controls the opening and closing of the air circuit, the on-site switch is a ball valve switch, the remote switch is a PLC, the signal generator is a disc limiter, and the air source can provide stable compressed air with an air pressure between 0.2MPa-0.6MPa.

[0005] As a preferred technical solution of the utility model, the solenoid valve can control the opening and closing of the blowing nozzle according to the electrical signal.

[0006] As a preferred technical solution of the utility model, the on-site switch is a ball valve switch, which achieves the purpose of shutting off the purge air normally closed by cutting off the air source.

[0007] As a preferred technical solution of the utility model, the remote switch is a PLC, and the purpose of closing the purge air normally closed is achieved by cutting off the electrical signal of the solenoid valve.

[0008] As a preferred technical solution of the utility model, the effect of the PLC program is that when the disc starts to move, it will trigger the signal generator to transmit a signal to the remote switch, and the remote switch will convert this signal into a three-second open signal and transmit it to the solenoid valve. When the remote switch is closed, it will stop transmitting the signal to the solenoid valve, and the solenoid valve will remain in a normally closed state.

[0009] The utility model has the following beneficial effects:

[0010] 1. When the copper mold is within the purging range and is in a moving state, the purge device starts and continues to purge for seconds to clean up the splashing debris. When the copper mold is not within the purging range and is in a moving state, the three-second timed purge state of the purge device just ends, and the purge stops to save the gas source. When the copper mold is within the purging range but is in a stationary state, the purge device does not purge to save the gas source.

[0011] 2. Fix the blowing nozzle on the side of the copper mold that needs to be cleaned. When the copper mold moves, the signal generator receives the copper mold movement signal and gives a purge signal. The solenoid valve opens, and the compressed air is ejected from the blowing nozzle to clean the side of the moving copper mold. When the side of the copper mold that needs to be cleaned leaves the range of the purge device, the solenoid valve closes. At this time, the second mold enters the purge position, and the purge device does not purge until the second mold starts to move and purges again. BRIEF DESCRIPTION OF THE DRAWINGS

In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the utility model in conjunction with the accompanying drawings.

[0015] The embodiment of the present application provides a blower for cleaning the surface of the disc casting mold, which effectively solves the problem that the splashing debris located on the top frame of the mold gradually accumulates and hooks together and falls into the gap between the push rod and the mold during pre-lifting or lifting. The nozzle 3 is fixed on the side of the copper mold 8 that needs to be cleaned. When the copper mold 8 moves, the signal generator 7 gives a blowing signal after receiving the copper mold 8 movement signal, the solenoid valve 4 is opened, and miscellaneous compressed air is sprayed from the blower 3 to clean the side of the moving copper mold 8 that needs to be cleaned. After the side of the copper mold 8 that needs to be cleaned leaves the range of the blower, the solenoid valve 4 is closed. At this time, the second mold enters the blowing position, and the blower does not blow until the second mold starts to move and blows again. Example

[0016] like Figure 1As shown, the technical solution in the embodiment of the present application effectively solves the problem that the splashing debris located on the top frame of the mold gradually accumulates and hooks together and falls into the gap between the ejector rod and the mold during pre-elevation or elevation. The overall idea is as follows:

[0017] In view of the problems existing in the prior art, the utility model provides a purge device for cleaning the surface of a disc casting mold, comprising an air source 1, a pipeline 2, a blowing nozzle 3, an electromagnetic valve 4, an on-site switch 5, a remote switch 6, a signal generator 7 and a copper mold 8. The air source 1 of the purge device is miscellaneous compressed air, the pipeline 2 is a rubber hose, the blowing nozzle 3 is a stainless steel pipe, the electromagnetic valve 4 controls the opening and closing of the air circuit, the on-site switch 5 is a ball valve switch, the remote switch 6 is a PLC, and the signal generator 7 is a disc limiter. The air source 1 can provide a stable compressed air with an air pressure between 0.2MPa and 0.6MPa. When the copper mold 8 is within the purge range and is in a moving state, the purge device starts and continues to purge for three seconds to clean up the splashing debris. When the copper mold 8 is not within the purge range and is in a moving state, the three-second timed purge state of the purge device just ends, and the purge stops, saving the air source 1. When the copper mold 8 is within the purge range but is in a stationary state, the purge device does not purge, saving the air source 1.

[0018] The solenoid valve 4 can control the opening and closing of the blowing of the blowing nozzle 3 according to the electrical signal. The on-site switch 5 is a ball valve switch. By cutting off the air source 1, the purpose of closing the purge air is achieved. The blowing nozzle 3 is fixed on the side of the copper mold 8 that needs to be cleaned. When the copper mold 8 moves, the signal generator 7 receives the movement signal of the copper mold 8 and gives a purge signal. The solenoid valve 4 opens, and the miscellaneous compressed air is ejected from the blowing nozzle 3 to clean the side of the moving copper mold 8 that needs to be cleaned.

[0019] The remote switch 6 is a PLC, which achieves the purpose of closing the normally closed state of the purge air by cutting off the electrical signal of the solenoid valve 4. The effect of the PLC program is that when the disc starts to move, it will trigger the signal generator 7 to transmit a signal to the remote switch 6. The remote switch 6 converts this signal into a three-second opening signal and transmits it to the solenoid valve 4. When the remote switch 6 is closed, it will stop transmitting the signal to the solenoid valve 4, and the solenoid valve 4 will remain in the normally closed state. After the side of the copper mold 8 to be cleaned leaves the range of the purger, the solenoid valve 4 is closed. At this time, the second mold enters the purge position, and the purger does not purge until the second mold starts to move and purges again.

[0020] Working principle:

[0021] When the copper mold 8 is within the purging range and is in a moving state, the blower starts and continues to purge for three seconds to clean the splashing debris. When the copper mold 8 is not within the purging range and is in a moving state, the three-second timed purging state of the blower just ends, and the purging stops to save the air source 1. When the copper mold 8 is within the purging range but is in a stationary state, the blower does not purge to save the air source 1. The nozzle 3 is fixed on the side of the copper mold 8 that needs to be cleaned. When the copper mold 8 moves, the signal generator 7 receives the copper mold 8 movement signal and gives a purging signal. The solenoid valve 4 opens, and the miscellaneous compressed air is ejected from the nozzle 3 to clean the side of the moving copper mold 8 that needs to be cleaned. After the side of the copper mold 8 that needs to be cleaned leaves the purging range, the solenoid valve 4 is closed. At this time, the second mold enters the purging position, and the blower does not purge until the second mold starts to move and is purged again.

[0022] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
