Description

Technical Field

[0001] This utility model relates to the field of die casting equipment technology, specifically to an integrated die casting mold cleaning, spraying and drying device. Background Technology

[0002] Die casting machines are key casting equipment that inject molten metal into a mold under high pressure to form a shape. Based on their working method, they can be divided into two main categories: hot chamber and cold chamber. Cold chamber machines can be further subdivided into vertical and horizontal structures. Their working principle utilizes a hydraulic system to generate powerful pressure, causing molten metal to fill the mold cavity at high speed. After rapid cooling and solidification, a precision casting is formed. Modern die casting machines, by precisely controlling parameters such as pressure, temperature, and speed, can efficiently produce metal products with accurate dimensions and smooth surfaces, offering significant advantages in the mass production of complex-shaped metal parts.

[0003] The authorization announcement number CN115533065B discloses a cold chamber die casting cavity release agent spraying system and method. According to its specification and drawings, the scheme is as follows: the nozzle assembly is installed in the middle of the airflow distribution plate. The airflow distribution plate is provided with an annular distribution chamber. The annular distribution chamber has an air inlet and multiple uniformly arranged air jets. The high-temperature compressed air sprayed from all the air jets and the mold surface together form a conical receiving space. The atomized release agent sprayed by the nozzle assembly enters the conical space and adheres to the mold surface.

[0004] The design of this jet nozzle has limitations: 1. The release agent cannot solidify immediately after being sprayed onto the inner wall of the die-casting tank, and a certain amount of time is required for the release agent to dry, which reduces production efficiency; 2. There will be certain impurities on the mold surface before each die-casting. If they cannot be effectively and quickly removed, it will obviously affect production efficiency. Summary of the Invention

[0005] This invention addresses the problems of cleaning molds and applying release agents during the die-casting process. It proposes an integrated die-casting mold cleaning, spraying, and drying device. Before die-casting, the movable pressure plate and the die-casting base are separated with the maximum distance between them. The telescopic cylinder extends into the gap so that the nozzle is aligned with the mold groove. At this time, the pressure tank or release fluid tank is activated and transported through the pipeline assembly. Finally, the fluid is sprayed into the mold groove through the nozzle, thereby cleaning the impurities and oxide layer in the mold groove or applying the release agent.

[0006] The objective of this invention is achieved through the following technical solution: an integrated die-casting mold cleaning, spraying, and drying device, comprising a movable pressure platform, a mold base disposed below the movable pressure platform, a telescopic mechanism provided on the outer side of the movable pressure platform, the telescopic end of the telescopic mechanism being able to extend into the gap between the mold base and the movable pressure platform, the telescopic end of the telescopic mechanism being provided with a nozzle capable of spraying liquid or gas, the nozzle outlet facing the surface of the mold base when the telescopic mechanism is in the extended state, and a release liquid tank capable of providing liquid and a pressure tank capable of providing gas respectively provided on the outer side of the telescopic mechanism, the release liquid tank and the pressure tank being connected to the nozzle through a pipeline assembly.

[0007] Preferably, the telescopic mechanism includes a telescopic support base and a telescopic cylinder mounted on the telescopic support base, with the nozzle disposed at the end of the telescopic cylinder.

[0008] Preferably, the piping assembly includes a first front-end rigid pipe, a first connecting hose, a second front-end rigid pipe, and a second connecting hose. The first front-end rigid pipe and the first connecting hose are connected and used to transport liquid. The second front-end rigid pipe and the second connecting hose are connected and used to transport gas. The nozzle is connected to the ends of the first front-end rigid pipe and the second front-end rigid pipe. One end of the second connecting hose is connected to a pressure tank. One end of the first connecting hose is connected to a release fluid tank. The release fluid tank is equipped with a hydraulic pump for discharging liquid. The pressure tank and the release fluid tank are combined into one unit.

[0009] Preferably, the first front rigid tube is sleeved outside the second front rigid tube, and the other ends of the first and second front rigid tubes are connected to one side of an intake valve with dual inlets and outlets. The other side of the intake valve is connected to the first connecting hose and the second connecting hose.

[0010] Preferably, the nozzle is a wide-angle swirling nozzle, which includes a concentric double-layer structure. The outer layer of the nozzle is connected to the end of the first front rigid tube, and the inner layer of the nozzle is connected to the end of the second front rigid tube. This design allows gas and liquid to be ejected through the same nozzle without affecting each other.

[0011] Preferably, the nozzle end is also provided with a self-regulating closing device that can open and close automatically. When the telescopic cylinder is in the retracted state, the self-regulating closing device blocks the nozzle outlet and thus is in a closed state.

[0012] Preferably, the telescopic cylinder is equipped with an infrared ranging sensor for determining whether the telescopic end has reached the designated position. The telescopic cylinder is also equipped with an indicator light, which illuminates when the nozzle is spraying liquid or gas. This design allows for more intuitive observation by the staff, thereby enabling better control, adjustment, and inspection.

[0013] Preferably, the connection between the pressure tank and the pipeline assembly is equipped with a temperature and humidity control drying device that can control the wind speed and temperature, and a pneumatic diaphragm pump is detachably connected to the release liquid tank, which can atomize the release agent in the release liquid tank.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. Before die casting, the movable pressure table and the die casting base are separated and the distance between them is at its maximum. The telescopic cylinder extends into the gap so that the nozzle is opposite to the mold groove. At this time, the pressure tank or the mold release liquid tank is started and transported through the pipeline assembly. Finally, it is sprayed into the mold groove through the nozzle, which can clean the impurities and oxide layer in the mold groove or spray the mold release agent, thus improving production efficiency. 2. The nozzle consists of an inner layer and an outer layer. The outer layer is connected to a first front rigid tube, and the inner layer is connected to a second front rigid tube. Therefore, when delivering gas, the gas enters one of the valve ports of the air inlet valve through the second connecting hose and is ejected through the second front rigid tube and the outer layer of the nozzle. When delivering the release agent, the release agent enters the other valve port of the air inlet valve through the first connecting hose and is ejected through the first front rigid tube and the inner side of the nozzle. This design allows gas and liquid to be ejected through the same nozzle without interfering with each other, and the gas ejection accelerates the drying speed of the release agent.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 As shown, an integrated die-casting mold cleaning, spraying, and drying device includes a movable pressure table 1 and a mold base 2 disposed below the movable pressure table 1. The mold base 2 has a mold groove 8. During die casting, the fired blank is placed in the mold groove 8. Then, the movable pressure table 1 is slid to close the movable pressure table 1 and the mold base 2, thereby pressing the blank into the desired shape.

[0018] Please continue to refer to this. Figure 2 The movable pressure table 1 is provided with a telescopic mechanism on its outer side. The telescopic end of the telescopic mechanism can extend into the gap between the mold base 2 and the movable pressure table 1. The telescopic end of the telescopic mechanism is provided with a nozzle 13 that can spray liquid or gas. The demolding liquid tank 6 and the pressure tank 5 are connected to the nozzle 13 through a pipeline assembly.

[0019] In this embodiment, the telescopic mechanism includes a telescopic support base 3 and a telescopic cylinder 4 mounted on the telescopic support base 3. The nozzle 13 is located at the end of the telescopic cylinder 4. Whenever the telescopic cylinder 4 is in the extended state, the outlet of the nozzle 13 faces the surface of the mold base 2. A release agent tank 6 for supplying liquid and a pressure tank 5 for supplying gas are also provided on the outer side of the telescopic mechanism. The nozzle 13 can blow the release agent in the release agent tank 6 or the gas in the pressure tank 5 into the mold groove 8.

[0020] Please continue to refer to this. Figure 3 , Figure 5 and Figure 6 In this embodiment, the piping assembly includes a first front rigid pipe 11, a first connecting hose 9, a second front rigid pipe 16, and a second connecting hose 10. The first front rigid pipe 11 and the first connecting hose 9 are connected and used to transport liquid. The second front rigid pipe 16 and the second connecting hose 10 are connected and used to transport gas. The nozzle 13 is connected to the ends of the first front rigid pipe 11 and the second front rigid pipe 16. One end of the second connecting hose 10 is connected to the inside of the pressure tank 5. One end of the first connecting hose 9 is connected to the inside of the release liquid tank 6. The release liquid tank 6 is equipped with a hydraulic pump for discharging liquid.

[0021] In this embodiment, for higher integration of the entire device, the pressure tank 5 and the release liquid tank 6 are combined into one unit, and the first front rigid tube 11 is fitted over the second front rigid tube 16. For better control of the air and liquid flow paths, the other ends of the first front rigid tube 11 and the second front rigid tube 16 are connected to one side of an air inlet valve 12 with dual inlets and outlets. The other side of the air inlet valve 12 is connected to the first connecting hose 9 and the second connecting hose 10. The air inlet valve 12 can function as an on / off switch when the release liquid tank 6 or the pressure tank 5 malfunctions.

[0022] Please continue to refer to this. Figure 4 The connection between the pressure tank 5 and the pipeline assembly is equipped with a temperature and humidity control drying device 18 that can control the wind speed and temperature. A pneumatic diaphragm pump 7 is detachably connected to the release liquid tank 6, which can atomize the release agent in the release liquid tank 6.

[0023] The air curtain drying module has three wind speeds. A temperature and humidity control drying device 18 is installed at the connection between the pipeline assembly and the pressure tank 5. The temperature and humidity control drying device 18 can control the wind speed and the outlet air temperature, thereby controlling the degree of drying of the release agent and adapting to different situations.

[0024] Since the release liquid tank 6 is detachably connected to the pneumatic diaphragm pump 7, when spraying the release agent, the pneumatic diaphragm pump 7 can atomize the release agent in the release liquid tank 6, which facilitates subsequent transportation and spraying. Depending on the required atomization effect, different strength pneumatic diaphragm pumps 7 can be disassembled and replaced.

[0025] To make this solution easier to understand: The telescopic cylinder 4, together with the nozzle 13, the first connecting hose 9, the first front rigid tube 11, the temperature and humidity control drying device 18, and the release liquid tank 6, form an atomizing spraying module. The atomizing spraying module sprays within the mold base 2. The telescopic cylinder 4, together with the nozzle 13, the second connecting hose 10, the second front rigid tube 16, the pressure tank 5 and the pneumatic diaphragm pump 7, form an air sweeping cleaning module or an air curtain drying module.

[0026] With this setup, the air-sweeping cleaning module can perform air-jet cleaning on the mold base 2, while the air curtain drying module can blow-dry the mold base 2 after spraying the release agent. It should be noted that the atomizing spraying module, air-sweeping cleaning module, and air curtain drying module share a common telescopic mechanism and nozzle 13.

[0027] Before die casting, the movable pressure table 1 is separated from the die casting base and the distance between them is at its maximum. The telescopic cylinder 4 on the telescopic support 3 extends into the gap, so that the nozzle is opposite to the mold groove 8. At this time, the air sweeping cleaning module is activated, the control valve of the air pressure tank 5 is opened, and the gas flows into the second connecting hose 10 and the second front rigid tube 16 in sequence for delivery. It is then sprayed into the mold groove 8 through the nozzle 13, thereby cleaning the impurities and oxide layer in the mold groove 8 to facilitate the subsequent die casting of the blank. After the air sweeping cleaning module finishes its work, the control valve of the air pressure tank 5 automatically closes, and the atomizing spraying module starts. At this time, the hydraulic pump opens and delivers the release agent in the release liquid tank 6 into the first connecting hose 9 and the first front rigid tube 11 in sequence. The release agent is then sprayed into the mold groove 8 through the nozzle, thereby completing the coating of the release agent. This facilitates the demolding of the blank after die casting. After the atomization spraying module is completed, the hydraulic pump is turned off to stop the coating of the release agent. Finally, the air curtain drying module is started. At this time, the control valve of the pressure tank 5 is started again, so that the gas in the pressure tank 5 flows into the second connecting hose 10 and the second front rigid pipe 16 in sequence for delivery, and is sprayed into the mold groove 8 through the nozzle 13, thereby drying the release agent in the mold groove 8 and improving the drying efficiency of the release agent.

[0028] Please continue to refer to this. Figure 5 The nozzle 13 is a wide-angle swirling nozzle, comprising a concentric double-layer structure. The outer layer of the nozzle 13 is connected to the end of the first front-end rigid tube 11, and the inner layer of the nozzle 13 is connected to the end of the second front-end rigid tube 16. The nozzle 13 is a 120° wide-angle swirling nozzle, a design that allows for more comprehensive spraying of gas and release agent, ensuring thorough spraying of the entire mold groove 8.

[0029] Specifically, nozzle 13 includes an inner layer 13-1 and an outer layer 13-2, wherein the outer layer 13-2 is connected to the first front rigid tube 11, and the inner layer 13-1 is connected to the second front rigid tube 16. Therefore, when conveying gas, the gas enters one of the valve ports of the air inlet valve 12 through the connecting hose 10, and is ejected through the second front rigid tube 16 and the outer layer 13-2 of the nozzle. When conveying mold release agent, the mold release agent enters the other valve port of the air inlet valve 12 through the first connecting hose 9, and is ejected through the first front rigid tube 11 and the inside of the nozzle 13. This design allows gas and liquid to be ejected not only through the same nozzle 13, but also to operate independently.

[0030] Please continue to refer to this. Figure 5The nozzle 13 is also equipped with a self-regulating closing device 17 that can automatically open and close. The wide-angle swirl nozzle 13 has a self-regulating closing device 17. When the air curtain drying module is completed and the telescopic cylinder 4 is in the retracted state, the self-regulating closing device 17 blocks the outlet of the nozzle 13 and is in a closed state. This design can automatically control the opening and closing of the nozzle 13. When no gas or release agent is sprayed, the wide-angle swirl nozzle is closed to prevent the liquid inside the wide-angle swirl nozzle from being exposed and drying, which would affect the spraying.

[0031] In this embodiment, the telescopic cylinder 4 is equipped with an infrared ranging sensor 15 for determining whether the telescopic end has reached the designated position. The infrared ranging sensor 15 can automatically sense the position when the telescopic cylinder 4 extends into the gap between the movable pressure table 1 and the mold seat 2, thereby achieving adaptive positioning.

[0032] In this embodiment, the telescopic cylinder 4 is also equipped with an indicator light 14, which illuminates when the nozzle 13 is spraying liquid or gas. Specifically, the indicator light 14 has both red and green colors. The indicator light 14 is connected to the air pipe and the liquid pipe; the green light illuminates when air is discharged from the air pipe, and the red light illuminates when liquid is discharged from the liquid pipe. This design allows the operation of the atomizing spraying module, the air sweeping cleaning module, and the air curtain drying module to be more intuitively observed by the workers, thereby enabling better control, adjustment, and inspection. Working principle and usage of this utility model: Before die casting, the movable pressure table 1 is separated from the die casting base and the distance between them is at its maximum. The telescopic cylinder 4 on the telescopic support 3 extends into the gap, so that the nozzle is opposite to the mold groove 8. At this time, the air sweeping cleaning module is activated, the control valve of the air pressure tank 5 is opened, and the gas flows into the second connecting hose 10 and the second front rigid tube 16 in sequence for delivery. It is then sprayed into the mold groove 8 through the nozzle 13, thereby cleaning the impurities and oxide layer in the mold groove 8 to facilitate the subsequent die casting of the blank. After the air sweeping cleaning module finishes its work, the control valve of the air pressure tank 5 automatically closes, and the atomizing spraying module starts. At this time, the hydraulic pump opens and delivers the release agent in the release liquid tank 6 into the first connecting hose 9 and the first front rigid tube 11 in sequence. The release agent is then sprayed into the mold groove 8 through the nozzle, thereby completing the coating of the release agent. This facilitates the demolding of the blank after die casting. After the atomization spraying module is completed, the hydraulic pump is turned off to stop the application of the release agent. Finally, the air curtain drying module is started. At this time, the control valve of the pressure tank 5 is started again, so that the gas in the pressure tank 5 flows into the second connecting hose 10 and the second front rigid pipe 16 in sequence for delivery, and is sprayed into the mold groove 8 through the nozzle 13, thereby drying the release agent in the mold groove 8 and improving the drying efficiency of the release agent. During die casting, the fired blank is placed in the mold groove 8, and then the movable pressure table 1 is slid to close with the mold base 2, thereby pressing the blank into the required shape.

[0033] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
