Description

Technical Field

[0001] The utility model relates to the technical field of die-casting supporting facilities, in particular to a water mist collecting device for a die-casting machine. Background Art

[0002] A die-casting machine is a machine used for pressure casting. It is mainly divided into vertical or horizontal hot chamber die-casting machines and vertical or horizontal cold chamber die-casting machines. It is mainly composed of a clamping mechanism, an injection mechanism, a hydraulic system, and an electric control system. During operation, the die-casting machine needs to spray water to cool the mold. In this process, the mold temperature is too high, which will cause the sprayed water vapor to turn into water mist, i.e., water vapor. In order to prevent the water mist from corroding the workshop structure and other equipment, it is necessary to collect the water mist through a water mist collection device and discharge it uniformly.

[0003] The water mist collection device for a die-casting machine with application number 202221143658.4 includes a frame and a collection hood with a collection chamber. The collection hood is divided into a moving part and a fixed part. The moving part is connected to the frame through a guide structure, and the moving part can move horizontally. The water mist collection device for a die-casting machine also includes a driving structure installed on the frame, and the output component of the driving structure is connected to the moving part. The driving structure can make the moving part move horizontally along the guide direction of the guide structure. The water mist collection device for a die-casting machine is equipped with a driving structure, which can drive the moving part to move horizontally in the guide direction of the guide structure. There is no need to manually move the collection hood. The use of automation technology greatly improves efficiency, and the staff is not easily pinched by the moving part, which improves safety.

[0004] This technical solution places the entire device on a guide rail, and then enables the moving part to move horizontally through a driving structure with an electric motor as the driver. The moving part is not only provided with an air collecting hood, but also with fans, pipelines and other structures. Increasing the weight of the moving part leads to an increase in the load, thereby increasing the energy consumption of the device. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a water mist collection device for a die-casting machine to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a water mist collection device for a die-casting machine, comprising a device body, a shell and a guide rail, the shell being located on the outer surface of the device body, and a guide roller being connected to the upper part of the shell, the guide rail being located on the outer surface of the shell, and a linear motor being installed on the top of the guide rail, the output end of the linear motor being connected to an air collecting hood, and a hose being connected to the back of the air collecting hood, and a counterweight being connected to the bottom of the hose.

[0007] By adopting the above technical solution, the air collecting hood can be moved left and right through the cooperation of the linear motor and the guide rail to increase the range of collecting water mist, and the linear motor only drives the air collecting hood to move horizontally and bears part of the pulling force in the direction of the hose. The load is small and the energy consumption is effectively reduced. At the same time, the counterweight block is affected by gravity and always applies a downward pulling force to the hose. When the air collecting hood is away from the shell, the hose extends from the shell and causes the counterweight block to move upward. At the same time, the diameter of the counterweight block is larger than the gap between the two guide rollers in the middle position, so as to prevent the hose from falling off the shell. When the air collecting hood is close to the shell, the counterweight block falls under the influence of gravity and collects the hose into the shell, so as to prevent the hose from being damaged due to arbitrary bending, entanglement and scattering.

[0008] Furthermore, the hose is in contact with the guide roller, and the hose is slidably connected to the shell.

[0009] By adopting the above technical solution, when the air collecting hood is away from the shell, the hose extends out from the shell and causes the counterweight to move upward. At the same time, the diameter of the counterweight is larger than the gap between the two guide rollers in the middle position, thereby preventing the hose from falling off the shell. When the air collecting hood is close to the shell, the counterweight falls under the influence of gravity and collects the hose into the shell, thereby preventing the hose from being damaged due to arbitrary bending, entanglement and scattering.

[0010] Furthermore, four guide rollers are provided, and the four guide rollers are equidistantly distributed.

[0011] By adopting the above technical solution, the guide roller is set to avoid wear between the hose and the shell, and the diameter of the counterweight block is larger than the gap between the two guide rollers in the middle position, thereby preventing the hose from falling off the shell.

[0012] Furthermore, a water pump is installed on one side of the device body, an axial flow fan is installed below the outer surface of the device body, and an exhaust port is opened on the top of the device body.

[0013] By adopting the above technical solution, after the axial flow fan is started, the air collecting hood sucks in the water mist generated around the die-casting machine. At this time, the water mist passes through the air collecting hood, the hose, the axial flow fan, the distribution pipe, the gap between the first hollow frame and the second hollow frame in sequence, and is then discharged from the exhaust port; after the water pump is started, water from the external water source is pumped into the first water inlet pipe, and then the water passes through the first water inlet pipe, the first hollow frame or the second hollow frame, and the second water inlet pipe in sequence, and then the water is sent to the die-casting machine through the second water inlet pipe for cooling.

[0014] Furthermore, the inside of the device body is respectively connected to a first hollow frame and a second hollow frame, and the top of the first hollow frame and the second hollow frame is connected to a first water inlet pipe, the bottom of the first hollow frame and the second hollow frame is connected to a second water inlet pipe, the outer surfaces of the first hollow frame and the second hollow frame are both connected to distribution pipes, and a one-way valve is installed at the bottom of one side of the device body.

[0015] By adopting the above technical solution, after the water pump is started, water from the external water source is pumped into the first water inlet pipe, and then the water passes through the first water inlet pipe, the first hollow frame or the second hollow frame, and the second water inlet pipe in sequence, and then the water is sent to the die-casting machine through the second water inlet pipe for cooling. When the water mist is in the gap between the first hollow frame and the second hollow frame, since the gap between the first hollow frame and the second hollow frame is maze-shaped, the water mist will collide with each other and with the first hollow frame and the second hollow frame during the rising process. At this time, the droplets in the water mist will combine with each other to increase the weight and fall down and separate from the water mist. At the same time, the water circulating in the first hollow frame and the second hollow frame will reduce the temperature of the water mist and condense and fall. Then the condensed water is sent to the die-casting machine through the one-way valve for cooling, or collected in the storage structure for other uses.

[0016] Furthermore, a plurality of the first hollow frames and a plurality of the second hollow frames are provided, and the plurality of first hollow frames and the plurality of second hollow frames are distributed alternately.

[0017] By adopting the above technical solution, the water mist will collide with each other and with the first hollow frame and the second hollow frame during the rising process. At this time, the droplets in the water mist will combine with each other to increase the weight and fall down and separate from the water mist. At the same time, the water flowing in the first hollow frame and the second hollow frame will reduce the temperature of the water mist and condense and fall.

[0018] Furthermore, the gap between the first hollow frame and the second hollow frame is in a maze shape.

[0019] By adopting the above technical solution, when the water mist is in the gap between the first hollow frame and the second hollow frame, since the gap between the first hollow frame and the second hollow frame is maze-shaped, the water mist will collide with each other and with the first hollow frame and the second hollow frame during the rising process.

[0020] Furthermore, the first hollow frame and the second hollow frame are both made of aluminum alloy.

[0021] By adopting the above technical solution, the aluminum alloy has good thermal conductivity and can transfer the heat in the water mist to the water for cooling the die-casting machine, thereby condensing the water mist and recovering water resources.

[0022] Furthermore, the air inlet end of the axial flow fan is connected to a hose, and the air outlet end of the axial flow fan is connected to a distribution pipe.

[0023] By adopting the above technical solution, after the axial flow fan is started, the air collecting hood sucks in the water mist generated around the die-casting machine. At this time, the water mist passes through the air collecting hood, the hose, the axial flow fan, the distribution pipe, the gap between the first hollow frame and the second hollow frame in sequence, and is then discharged from the exhaust port.

[0024] Furthermore, the water outlet of the water pump is connected to the first water inlet pipe.

[0025] By adopting the above technical solution, after the water pump is started, water from the external water source is pumped into the first water inlet pipe, and then the water passes through the first water inlet pipe, the first hollow frame or the second hollow frame, and the second water inlet pipe in sequence, and then the water is sent into the die-casting machine through the second water inlet pipe for cooling.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] The utility model is provided with a shell, a guide rail, a linear motor, an air collecting hood, a hose, a guide roller and a counterweight block. The linear motor cooperates with the guide rail to enable the air collecting hood to move left and right to increase the range of collecting water mist, and the linear motor only drives the air collecting hood to translate and bears a part of the pulling force in the direction of the hose. The load is small and the energy consumption is effectively reduced. At the same time, the counterweight block is affected by gravity and always applies a downward pulling force to the hose. When the air collecting hood is away from the shell, the hose extends from the shell and causes the counterweight block to move upward. At the same time, the diameter of the counterweight block is larger than the gap between the two guide rollers in the middle position, so that the hose is prevented from falling off the shell. When the air collecting hood is close to the shell, the counterweight block falls under the influence of gravity and collects the hose into the shell, so that the hose is prevented from being damaged due to arbitrary bending, entanglement and scattering. The load is small and the energy consumption is effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] See also Figure 1 , Figure 2 and Figure 4In the above embodiment, the first hollow frame 16 and the second hollow frame 17 are respectively connected inside the device body 1, and the first hollow frame 16 and the second hollow frame 17 are provided with a plurality of them, and the plurality of first hollow frames 16 and the plurality of second hollow frames 17 are staggered. The gap between the first hollow frame 16 and the second hollow frame 17 is in a maze shape. The first hollow frame 16 and the second hollow frame 17 are both made of aluminum alloy material. The water mist will collide with each other and with the first hollow frame 16 and the second hollow frame 17 during the rising process. At this time, the droplets in the water mist will combine with each other to increase the weight and fall and separate from the water mist. At the same time, the water flowing in the first hollow frame 16 and the second hollow frame 17 will reduce the temperature of the water mist and condense and fall; the first hollow frame 16 and the second hollow frame 17 A first water inlet pipe 10 is connected to the top of the hollow frame 17, and the water outlet end of the water pump 9 is connected to the first water inlet pipe 10. The second water inlet pipe 11 is connected to the bottom of the first hollow frame 16 and the second hollow frame 17. Water passes through the first water inlet pipe 10, the first hollow frame 16 or the second hollow frame 17, and the second water inlet pipe 11 in sequence, and then the water is sent to the die-casting machine through the second water inlet pipe 11 for cooling; the outer surfaces of the first hollow frame 16 and the second hollow frame 17 are both connected to the distribution pipe 14, and the air outlet end of the axial flow fan 13 is connected to the distribution pipe 14. A one-way valve 15 is installed at the lower side of the device body 1. Condensed water is sent to the die-casting machine for cooling through the one-way valve 15, or collected in the storage structure for other uses, effectively recovering the moisture in the water mist and reducing resource waste.

[0041] The implementation principle of the utility model is as follows: first, after the axial flow fan 13 is started, the air collecting hood 5 sucks the water mist generated around the die casting machine, and at this time, the water mist passes through the air collecting hood 5, the hose 6, the axial flow fan 13, the distribution pipe 14, the gap between the first hollow frame 16 and the second hollow frame 17 in sequence, and then is discharged from the exhaust port 12;

[0042] After the water pump 9 is started, the water in the external water source is pumped into the first water inlet pipe 10, and then the water passes through the first water inlet pipe 10, the first hollow frame 16 or the second hollow frame 17, and the second water inlet pipe 11 in sequence, and then the water is sent into the die-casting machine through the second water inlet pipe 11 for cooling;

[0043] When the water mist is in the gap between the first hollow frame 16 and the second hollow frame 17, since the gap between the first hollow frame 16 and the second hollow frame 17 is in a maze shape, the water mist will collide with each other and with the first hollow frame 16 and the second hollow frame 17 during the rising process. At this time, the droplets in the water mist will combine with each other to increase the weight and fall down and separate from the water mist. At the same time, the water flowing in the first hollow frame 16 and the second hollow frame 17 will reduce the temperature of the water mist and condense and fall down. After that, the condensed water is sent to the die-casting machine through the one-way valve 15 for cooling, or collected in the storage structure for other uses.

[0044] At the same time, the linear motor 4 can cooperate with the guide rail 3 to make the air collecting hood 5 move left and right to increase the range of collecting water mist, and the linear motor 4 only drives the air collecting hood 5 to move horizontally and bears part of the pulling force in the direction of the hose 6. The load is small and the energy consumption is effectively reduced. At the same time, the counterweight 8 is affected by gravity and always applies a downward pulling force to the hose 6. When the air collecting hood 5 is away from the shell 2, the hose 6 extends out of the shell 2 and moves the counterweight 8 upward. At the same time, the diameter of the counterweight 8 is larger than the gap between the two guide rollers 7 in the middle position, which prevents the hose 6 from falling off from the shell 2. When the air collecting hood 5 is close to the shell 2, the counterweight 8 falls under the influence of gravity and collects the hose 6 into the shell 2, which prevents the hose 6 from being damaged due to arbitrary bending, entanglement and scattering.
