Description

Technical Field

[0001] The present invention relates to the field of casting, and particularly to an integrated die-casting large box-type spraying device. Background Art

[0002] The integrated die-casting technology has been widely applied in modern manufacturing industries, especially in fields such as automotive and aerospace, for producing large and complex components. During the integrated die-casting process, in order to ensure that the casting can be smoothly ejected from the mold while ensuring the service life of the mold and the surface quality of the casting, the spraying of the release agent is crucial. However, there are many problems with the existing spraying devices when dealing with large box-type molds for integrated die-casting.

[0003] On the one hand, due to the large volume and complex structure of the large box-type mold, it is difficult for traditional spraying devices to achieve comprehensive and uniform spraying. Existing devices often cannot flexibly adjust the spraying height, angle, and range, resulting in insufficient spraying in some areas of the mold and excessive spraying in some areas, which not only affects the demolding effect of the casting but also causes waste of the release agent.

[0004] On the other hand, the existing spraying equipment lacks an efficient stirring and conveying system for large box-type molds. The release agent is prone to precipitation and stratification during storage and use. If the stirring is not sufficient, it will lead to uneven composition of the sprayed release agent, affecting the demolding effect. Moreover, for the large amount of release agent required for large molds, the existing conveying methods are inefficient and cannot meet the needs of rapid production. Summary of the Invention

[0005] The purpose of the present invention is to provide an integrated die-casting large box-type spraying device to solve at least one of the above technical problems.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0010] The stirring and spraying assembly is arranged on the storage tank and includes a stirring component and a plurality of nozzles with adjustable angles for stirring the release agent and achieving multi-angle spraying;

[0011] The control module is electrically connected to the lifting mechanism, the stirring component, and the nozzles for controlling the operation of each component;

[0016] Furthermore, the drying component includes a heating box, a fan and a hot air duct. The heating box is provided with a heating element for heating the air. The fan draws outside air into the heating box, and after heating, it is transported to the mold surface through the hot air duct. The outlet of the hot air duct is arranged on the movable rod and on the same side as the nozzle.

[0017] Further, a laser distance sensor is provided at the bottom of the agent storage box for measuring the distance value between the bottom of the agent storage box and the upper surface of the mounting frame. The movable rod comprises an upper rod body and a lower rod body. The lower rod body is rotatably mounted on the bottom end of the upper rod body. A gear is sleeved on the lower rod body. The gear is meshed with a transmission tooth for transmission. The transmission tooth is rotatably mounted on the outer side wall of the upper rod body through a bracket. The transmission tooth is transmission-connected to a driving motor installed at the bottom of the bracket.

[0018] When the tank reaches the bottom set position, the drive motor drives the lower rod to rotate to spray the mold on the other side. When the tank reaches the top set position, the drive motor drives the lower rod to rotate back to the initial position.

[0019] Furthermore, the uniform wind component includes an air outlet and a guide plate. A plurality of evenly distributed air outlets are arranged at the outlet of the hot air duct.

The vertical plate is limited and slidably installed at the outlet of the hot air pipe.

[0021] Further, the connecting plate gradually bends downward as it moves away from the air outlet, forming an arc transition, so that the farther the top rod is from the air outlet, the more it pushes the connecting plate and the vertical plate upward, causing the plurality of guide plates to be in a synchronous upward inclined posture.

[0022] Advantages of the present invention:

[0023] In the present invention, the wrapping design of the sleeve for the nozzle forcibly contracts the spraying range of the release agent through physical constraints, avoiding uneven edge thickness caused by the diffusion of atomized particles, and enabling the release agent to form a uniform coating on the surface of the mold, especially suitable for precise spraying of complex curved surface molds; at the same time, after the baffle extends out, the isolation area is enlarged, physically separating the hot air from the fresh spraying area, preventing the high-temperature air flow from blowing away the unadhered release agent, and reducing problems such as excessive local drying and coating cracking caused by "spraying while drying"; at the same time, the upward inclination of the guide plate changes the flow direction of the hot air, enabling the hot air to preferentially cover the sprayed and dried areas, forming an orderly operation process of "spraying - isolation - drying".

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-5 As shown, the present invention is an integrated die-casting large box-type spraying device, including: a mounting frame 1, a lifting mechanism 2, an agent storage tank 3, a stirring and spraying assembly 4, and a control module;

[0033] The lifting mechanism 2 is installed on the mounting frame 1 and is connected to the agent storage tank 3 for adjusting the height of the agent storage tank 3;

[0034] The agent storage tank 3 is arranged on the lifting mechanism 2 for storing the release agent;

[0035] The stirring and spraying assembly 4 is arranged on the agent storage tank 3, including a stirring component and a plurality of nozzles 44 with adjustable angles for stirring the release agent and realizing multi-angle spraying;

[0036] The control module is electrically connected to the lifting mechanism 2, the stirring component, and the nozzle 44 for controlling the operation of each component;

[0037] The agent storage box 3 is also provided with a drying component 5 and a uniform wind component 6. The drying component 5 is used to dry the sprayed release agent with hot air, and the uniform wind component 6 is used to achieve uniform distribution of hot air in conjunction with the drying component 5. The control module includes a controller, an operation panel and a communication module. The operation panel is used to input control instructions, and the communication module is used to exchange data with external devices. The controller controls the operation of each component according to the instructions input by the operation panel and the data fed back by the liquid level sensor 48.

[0038] The lifting mechanism 2 includes a screw rod 21, a guide rail 22, a slider 23 and a drive motor 24, wherein the screw rod 21 is connected to the output shaft of the drive motor 24, the slider 23 is threadedly connected to the screw rod 21 and slidably connected to the guide rail 22, and the agent storage box 3 is fixedly mounted on the slider 23;

[0039] The stirring component includes a stirring motor 41, a stirring shaft 42 and a stirring blade 43. The stirring motor 41 is installed on the top of the storage box 3. The stirring shaft 42 is connected to the output shaft of the stirring motor 41 and extends into the storage box 3. The stirring blade 43 is fixedly installed on the stirring shaft 42.

[0040] The spray head 44 is connected to the agent storage tank 3 through an angle-adjustable connecting arm, and the connecting arm includes a fixed rod 45, a movable rod 46 and a rotating motor 47. The fixed rod 45 is fixed on the agent storage tank 3, and one end of the movable rod 46 is connected to the fixed rod 45 through the rotating motor 47, and the other end is connected to the spray head 44. A liquid level sensor 48 is provided in the agent storage tank 3, and the control module is electrically connected to the rotating motor 47 and the liquid level sensor 48. The spray head 44 includes three parts: a pump, a water pipe and a spray head. The pump is used to pressurize the release agent through the water pipe and spray it out from the spray head.

[0041] In the present invention, when it is necessary to spray the release agent on the integrated die-casting mold, the operator inputs a control instruction through the operation panel. After receiving the instruction, the controller controls the driving motor 24 of the lifting mechanism 2 to operate according to the demand, and the driving motor 24 drives the screw rod 21 to rotate. The rotation of the screw rod 21 causes the slider 23 threadedly connected thereto to move up and down along the guide rail 22, thereby realizing the adjustment of the height of the storage box 3 to adapt to molds of different heights; at the same time, the controller controls the stirring motor 41 to start, and the stirring motor 41 drives the stirring shaft 42 and the stirring blade 43 to rotate, so as to stir the release agent in the storage box 3 to ensure the uniformity of the release agent; when spraying, the controller controls the pump of the spray head 44 to start, and the pump pressurizes the release agent through the water pipe and sprays it from the spray head; and the controller controls the rotation motor 47 of the connecting arm to rotate according to the preset program or the instruction of the operation panel, so that the movable rod 46 drives the spray head 44 to adjust the angle, so as to realize multi-angle spraying of the release agent;

[0042] The liquid level sensor 48 monitors the liquid level of the release agent in the agent storage tank 3 in real time and feeds the data back to the controller; when the liquid level is too low, the controller can send an alarm message to an external device through the communication module to remind the operator to add the release agent; through the above solution, on the one hand, through the unified control of the lifting mechanism 2, the stirring component and the nozzle 44 by the control module, it is possible to automatically adjust the height of the agent storage tank 3, stir the release agent, and adjust the angle of the nozzle 44 according to different mold requirements, improving the accuracy and efficiency of spraying. When facing molds of different heights and shapes, there is no need to manually adjust each component, and the device can quickly respond and complete the corresponding operations, greatly saving time and labor costs;

[0043] On the other hand, the continuous stirring of the release agent by the stirring component ensures the uniformity of the release agent, improves the spraying quality, and reduces product appearance defects and mold sticking problems caused by uneven release agent; the nozzle 44 with adjustable angle can achieve multi-angle spraying to ensure that the release agent covers every corner of the mold, further improving the demolding effect; at the same time, the setting of the liquid level sensor 48 and the application of the communication module realize the real-time monitoring and remote alarm of the liquid level of the release agent in the agent storage tank 3, avoiding the situation that production is affected due to insufficient release agent, and improving the continuity and stability of production.

[0044] The drying component 5 includes a heating box 51, a blower 52, and a hot air duct 53. A heating element, such as an electric heating wire, is provided in the heating box 51 for heating the air; the blower 52 sucks external air into the heating box 51, and after heating, it is transported to the surface of the mold through the hot air duct 53. The outlet of the hot air duct 53 is arranged on the movable rod 46 and on the same side as the nozzle 44.

[0045] A laser distance sensor is provided at the bottom of the agent storage tank 3 for measuring the distance value between the bottom of the agent storage tank 3 and the upper surface of the mounting frame 1. The movable rod 46 includes an upper rod body 461 and a lower rod body 462. The lower rod body 462 is rotatably installed at the bottom end of the upper rod body 461. A gear 7 is sleeved on the lower rod body 462. The gear 7 is in transmission connection with the transmission tooth 8. The transmission tooth is rotatably installed on the outer side wall of the upper rod body 461 through a bracket 9. The transmission tooth is in transmission connection with a drive motor 10 installed at the bottom of the bracket 9;

[0046] After the agent storage tank 3 reaches the bottom set position point, the drive motor 10 drives the lower rod body 462 to rotate to spray the other side of the mold. After the agent storage tank 3 reaches the top set position point, the drive motor 10 drives the lower rod body 462 to rotate back to the initial position.

[0047] In the present invention, during spraying, first, it moves from top to bottom to spray one side. The laser distance sensor at the bottom of the agent storage tank 3 monitors the distance between the agent storage tank 3 and the mounting frame 1 in real time. When the agent storage tank 3 descends to the set position point at the bottom, the control module triggers the driving motor 10 to drive the lower rod body 462 of the movable rod 46 to rotate. After returning to the set position point at the top from bottom to top, it then moves from top to bottom again, causing the nozzle 44 to turn to the other side of the mold for spraying. After spraying is completed, the agent storage tank 3 rises to the set position point at the top, and the driving motor 10 operates again, and the lower rod body 462 turns back to the initial position. During this process, the outlet of the hot air duct 53 is fixed to the movable rod 46 and on the same side as the nozzle 44. No matter how the angle of the nozzle 44 is adjusted, the hot air can always accurately cover the spraying area of the nozzle 44. At the same time, the liquid level sensor 48 in the agent storage tank 3 monitors the stock of the release agent in real time. When the liquid level is insufficient, it feeds back to the control module, and the control module can pause the spraying operation and issue an alarm. Through the linkage of the laser distance sensor and the driving motor 10, automatic multi-angle switching spraying of the nozzle 44 is achieved, without manual intervention, improving the spraying efficiency. The integrated angle adjustment design of the hot air duct 53 and the nozzle 44 ensures that the hot air can always match the spraying direction of the nozzle 44 in real time, ensuring rapid drying of the release agent and avoiding problems such as flow marks and non-drying. The linkage of the liquid level sensor 48 and the overall control ensures the continuity and stability of the spraying operation, realizing the integration of multiple functions such as position monitoring, spraying angle adjustment, drying operation, and material monitoring, achieving multiple benefits with one action.

[0048] The air distribution component 6 includes an air outlet 61 and a guide plate 62. A plurality of uniformly distributed air outlets 61 are provided at the outlet of the hot air duct. At the corresponding position at the bottom of each air outlet 61, a guide plate 62 is hingedly provided. An auxiliary isolation component 11 is also provided at the outlet of the hot air duct, and the auxiliary isolation component 11 is used to isolate the release agent sprayed by the nozzle 44.

[0049] The auxiliary isolation component 11 includes a semi-circular baffle 111. The top end of the baffle 111 is provided with a top rod 112, and the bottom end of the top rod 112 is fixedly connected to the top of the baffle 111. A sliding part 113 is fixedly provided on the outer side wall of one end of the baffle 111. The sliding part 113 is limit slidably connected in a chute 115 opened on the inner side wall of a sleeve 114. The sleeve 114 is fixedly sleeved outside the nozzle 44. A spring 116 is provided between the sliding part 113 and the chute 115. The top end of the top rod 112 is movably connected to a limit groove 118 opened on the bottom surface of a connecting plate 117. The connecting plate 117 is fixedly connected to the bottom end of a vertical plate 119. One ends of the plurality of guide plates 62 are commonly hinged on the vertical plate 119, and the vertical plate 119 is limit slidably installed at the outlet of the hot air duct.

[0050] The connecting plate 117 is gradually bent downward as it moves away from the air outlet 61, forming an arc transition, so that the farther the ejector rod 112 is from the air outlet 61, the more it pushes the connecting plate 117 and the vertical plate 119 upward, causing the plurality of deflector plates 62 to be tilted upward synchronously.

[0051] In this embodiment, in order to avoid the problem of inconsistent spraying thickness of the release agent caused by the dispersion of the release agent sprayed by the nozzle 44, a sleeve 114 is provided to cover the nozzle 44, so that the sprayed release agent can be concentrated to improve the spraying uniformity of the release agent. At the same time, during the actual spraying process, the greater the spraying pressure, the more concentrated the release agent sprayed by the nozzle 44, so the greater the pushing force on the baffle 111, and thus the baffle 111 will extend outward. The covering range after the baffle 111 extends outward is used for compensation. On the one hand, it can expand the isolation degree between the hot air for hot air drying and the release agent below, reduce the interference caused by drying while spraying, improve the spraying quality and ensure the drying effect at the same time. On the other hand, when the baffle 111 extends outward, it will drive the ejector rod 112 to move. The ejector rod 112 then moves along the limit groove 118 formed on the bottom surface of the connecting plate 117. Since the connecting plate 117 is gradually bent downward as it moves away from the air outlet 61, forming an arc transition, it will gradually lift the connecting plate 117 upward. The connecting plate 117 drives the vertical plate 119 and the corresponding deflector plate 62 to deflect upward, so that the hot air ejected from the air outlet 61 is tilted upward, expanding the isolation area between the hot air and the release agent sprayed below, allowing the sprayed release agent to fully adhere and then be effectively dried, thus ensuring the drying effect while taking into account the spraying quality.

[0052] Through the above technical solutions, on the one hand, the wrapping design of the sleeve 114 for the nozzle 44 forcibly contracts the spraying range of the release agent through physical constraints, avoiding uneven edge thickness caused by the diffusion of atomized particles, and enabling the release agent to form a uniform coating on the mold surface, especially suitable for precise spraying of complex curved surface molds. On the other hand, after the baffle 111 extends outward, the isolation area is expanded, physically separating the hot air from the freshly sprayed area, preventing the high-temperature air flow from blowing away the unadhered release agent, and reducing the problems of local over-drying and coating cracking caused by "spraying while drying". At the same time, the deflector plate 62 tilts upward to change the hot air flow direction, enabling the hot air to preferentially cover the sprayed and dried areas, forming an orderly operation process of "spraying - isolation - drying".

[0053] Since the spraying pressure is positively correlated with the outward extension amplitude of the baffle 111, when spraying a high-viscosity release agent or spraying in a large flow rate, a higher pressure will push the baffle 111 to expand further, automatically enhancing the isolation effect. Conversely, when spraying in a small flow rate, the baffle 111 contracts, reducing the resistance of the hot air path and ensuring the uniformity of the hot air, realizing pressure-action linkage feedback.

[0054] The angle of the deflector 62 changes dynamically with the movement of the baffle 111. When the hot air flow rate increases, the air flow pushes the vertical plate 119 to synchronously increase the inclination angle of the deflector 62, expanding the coverage range of the hot air; when the hot air flow rate decreases, the deflector 62 automatically falls back to avoid heat waste, achieving a dynamic balance between drying efficiency and energy consumption, and realizing intelligent adjustment of hot air - deflector;

[0055] Finally, through mechanical linkage, the three processes of spraying, isolation, and drying are closely coupled, eliminating the risk of action delay or timing disorder in the traditional independent control mode, ensuring that all components can still cooperate precisely under high - speed spraying conditions, and greatly improving production efficiency and product yield.

[0056] The above has described a detailed implementation example of the present invention, but the content described is only the preferred implementation example of the present invention and cannot be considered as used to limit the implementation scope of the present invention. All equivalent changes and improvements made according to the scope of the present invention application should still fall within the patent coverage scope of the present invention.
