Description

Technical Field

[0001] The utility model relates to the technical field of spray machine maintenance, in particular to an automatic cleaning device for a spray machine. Background Art

[0002] A die-casting machine is a device used for metal casting. It is mainly used to inject molten metal into a precision mold under high pressure to form metal parts with complex shapes. The sprayer plays an auxiliary role in the die-casting process. During the die-casting process, the mold will heat up rapidly due to the injection of high-temperature molten metal. The sprayer can spray coolant onto the mold surface to help the mold cool down quickly, keep the mold within the appropriate operating temperature range, and avoid deformation or damage to the mold due to excessive temperature.

[0003] After a sprayer has not been used for a long time, the nozzle may become clogged due to the accumulation of residual lubricant, coolant, or other impurities. To ensure the normal operation of the sprayer and extend its service life, regular cleaning and maintenance are necessary. To this end, an automatic cleaning device for the sprayer is proposed to solve the above problem. Utility Model Content

[0004] The utility model aims to provide an automatic cleaning device for a sprayer, which has the advantage of cleaning the sprayer nozzle and solves the problem that the nozzle is blocked and the normal operation of the equipment is difficult.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an automatic cleaning device for a sprayer, comprising a cylinder, a connecting pipe being connected and installed at the top of the cylinder, a bottom shell being fixedly installed at the bottom of the cylinder, and further comprising a delivery pipe and a pressure pump;

[0006] The delivery pipe is connected and installed on the connecting pipe;

[0007] The pressure pump is embedded in the bottom of the bottom shell;

[0008] Among them, an exhaust pipe is installed on the top of the pressure pump;

[0009] Among them, an air intake pipe is connected and installed on one side of the pressure pump.

[0010] When using the automatic cleaning device for a sprayer according to the present technical solution, check the filter assembly at the top of the air inlet pipe to ensure that the sponge block in the filter assembly can properly filter impurities in the cleaning liquid. Ensure that the sprayer is in the off state and check that all connecting parts are intact and leak-free. Close the first control valve and the second control valve, open the sealing cap at the top of the liquid filling pipe, and inject an appropriate amount of cleaning liquid into the cylinder through the liquid filling pipe, ensuring that the amount of cleaning liquid is sufficient for cleaning. After injecting the cleaning liquid, reinstall the sealing cap to ensure good sealing to prevent leakage of the cleaning liquid. Start the pressure pump and pressurize the inside of the cylinder through the exhaust pipe at the top of the pressure pump. Open the second control valve on the connecting pipe to allow the cleaning liquid to be discharged through the connecting pipe. The cleaning liquid is then transported to the nozzle through the connecting pipe. The high pressure and fluidity of the cleaning liquid are used to flush the dried coolant in the nozzle, ensuring that all areas inside the nozzle are covered with the cleaning liquid. After cleaning is complete, close the second control valve on the connecting pipe to stop the flow of the cleaning liquid. Check that the nozzle is clean. Repeat the above steps if necessary. After thorough cleaning is complete, restore all components to their original state to ensure that the sprayer can be used normally.

[0011] Preferably, a hole is opened on the upper side of the cylinder and is connected to a liquid adding pipe, and a sealing cover is threadedly installed on the top of the liquid adding pipe.

[0012] The sealing cap threaded on the top of the filling tube provides a convenient and well-sealed filling port. This design makes adding cleaning fluid to the cylinder simple and quick.

[0014] The second control valve is fixedly installed on the connecting pipe, so that the operator can easily control the opening and closing between the connecting pipe and the cylinder. This design improves the flexibility of operation and control accuracy.

[0015] Preferably, the bottom shell is fixedly mounted on the bottom of the cylinder by means of mounting screws, and the bottom of the bottom shell adopts an open structure design.

[0016] The bottom shell is fixed to the bottom of the cylinder by mounting screws, and its bottom adopts an open structure design, which makes it easy to install the booster pump.

[0017] Preferably, a first control valve is fixedly installed on the delivery pipe, and one end of the delivery pipe away from the connecting pipe is connected to the coolant delivery mechanism.

[0018] The first control valve on the delivery pipe allows the operator to control the opening and closing of the coolant pipeline, ensuring that the cleaning liquid can flow smoothly to the nozzle without being injected into the coolant delivery mechanism.

[0019] Preferably, a filter assembly is movably mounted on the top of the air intake pipe, a connecting frame is fixedly mounted on the air intake pipe, and a side of the connecting frame facing away from the air intake pipe is fixedly mounted on the outside of the cylinder.

[0020] The filter assembly that is movably mounted on the top of the intake pipe and the fixed connection bracket provide an effective and firmly installed air filtration system.

[0021] Preferably, the filter assembly is threadedly mounted on the top of the air inlet pipe, and the filter assembly has a replaceable sponge block built in.

[0022] The threaded installation design of the filter assembly makes its installation and removal simple and quick, and it is convenient to replace the filter material regularly. The built-in replaceable sponge block provides a continuous filtering effect, ensuring the cleanliness of the cleaning fluid and preventing impurities from entering the system and affecting the cleaning effect and equipment performance.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The utility model provides a pressure boosting pump, and the pressure boosting pump provides stable pressure, which ensures that the cleaning liquid can pass through the nozzle with sufficient pressure, effectively removing the dried coolant and impurities inside the nozzle, and the cleaning liquid is transported from the cylinder to the nozzle through the connecting pipe, ensuring that every corner of the nozzle is covered with the cleaning liquid, avoiding cleaning dead corners, and injecting the cleaning liquid through the liquid filling pipe on the top of the cylinder. The operation is simple and the amount of the cleaning liquid is easy to control. The design of the exhaust pipe and the air inlet pipe can effectively increase the pressure inside the cylinder, so that the cleaning liquid in the cylinder is released under the action of pressure, thereby achieving the effect of cleaning the sprayer nozzle.
