Description

Technical Field

[0001] This utility model belongs to the technical field of die casting machine equipment, and in particular relates to a spray structure of a die casting machine spray head. Background Technology

[0002] In die casting production, release agent spray nozzles atomize the release agent using air pressure or hydraulic pressure to uniformly coat the mold surface. The core principle is to use pressure to break the release agent into tiny droplets. Existing spray nozzles operate by using compressed air to expel the release agent into tiny droplets (typically 2-3 micrometers in diameter) for air pressure atomization, or by using a pressure pump in conjunction with the nozzle structure to achieve atomization (higher pressure results in smaller droplets), while a built-in regulating valve controls the flow rate to ensure a uniform coating.

[0003] However, conventional spray heads have drawbacks, such as difficulty in flexibly adjusting the atomization width, easy occurrence of uneven spraying, and inability to adapt to the diverse atomization requirements of different die-casting processes, which affect the quality of release agent coating and die-casting production efficiency. Therefore, a die-casting machine spray head structure that can optimize atomization effect and improve spray uniformity is needed, and this patent was developed accordingly. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a spray structure for a die-casting machine spray head. It features precise control of material output through multiple adjustable components, flexible adjustment of the atomization width range, a combination of dual air sources and a reasonable channel layout, and an easily detachable nozzle and atomizing cap structure. This achieves uniform and delicate spraying, adaptability to various die-casting processes, and improves the quality of release agent coating and die-casting production efficiency. It solves the problems of conventional spray heads in the prior art, which struggle to flexibly adjust the atomization width, easily resulting in uneven spraying, inability to adapt to the diverse atomization requirements of different die-casting processes, and thus affecting the quality of release agent coating and die-casting production efficiency.

[0005] This utility model is implemented as follows: a spray structure for a die-casting machine spray head includes a spray head body. The output end of the spray head body is equipped with a nozzle and an atomizing cap. The nozzle has a material discharge channel and an air outlet channel inside. The top of the spray head body is equipped with three adjustment components: a material discharge size adjustment switch for adjusting the material discharge size, an atomization width adjustment switch for adjusting the atomization width, and an air pressure adjustment switch for adjusting the main air pressure. The output end of the spray head body is also equipped with a material inlet channel, an air inlet channel, and an air outlet channel, and the air inlet channel and the air outlet channel are connected, adopting a dual air source spraying method with one inlet and two outlets.

[0006] This setup enables multi-dimensional and precise control of the spraying process. The discharge size adjustment switch allows for precise control of the release agent dosage based on mold size and die-casting requirements, avoiding waste or insufficiency. The atomization width adjustment switch facilitates flexible adjustment of the atomization range, adapting to mold surfaces of different shapes and sizes. The main air pressure adjustment switch adjusts the atomization intensity in conjunction with the release agent's characteristics. Combined with the dual air source design (one inlet and two outlets), the airflow and release agent are mixed more thoroughly, ultimately resulting in a significant improvement in the uniformity and fineness of the spray. This meets the atomization requirements of different die-casting processes, improves the release agent coating quality, and enhances die-casting production efficiency.

[0007] As a preferred embodiment of this utility model, a water inlet piston switch is installed on the side wall of the spray head body, and the bottom of the spray head body is provided with a main airflow inlet, a fan-shaped wide and narrow air inlet, a feed inlet and a switch control air inlet, and the components work together to achieve the spraying function.

[0008] This setup allows the water inlet piston switch to flexibly control the water flow. The arrangement of the main airflow inlet and the fan-shaped wide and narrow air inlets ensures a clear and orderly path for the air source and material transport, reduces pipeline interference, and enables all components to work together to ensure stable airflow and smooth feeding, further guaranteeing the stability and reliability of the spraying process.

[0009] In a preferred embodiment of this invention, the atomizing cap is tightly fitted onto the outside of the nozzle, and an external threaded ring is fixedly connected to the upper middle part of the spray head body, with the bottom of the atomizing cap threadedly fitted onto the external threaded ring.

[0010] With this design, the atomizing cap is tightly fitted onto the outside of the nozzle and connected to the external threaded ring. This ensures stable movement of airflow and droplets during atomization and allows for quick assembly and disassembly of the atomizing cap. It facilitates the replacement of the appropriate atomizing cap according to different atomization needs. At the same time, the threaded connection provides good sealing, preventing air pressure leakage from affecting the atomization effect and improving the equipment's versatility and maintenance efficiency.

[0011] As a preferred embodiment of this utility model, an internal thread groove is provided in the middle cavity of the spray head body corresponding to the external thread ring, and the bottom thread of the nozzle is inserted into the internal thread groove.

[0012] This design ensures a secure nozzle installation by matching the threaded engagement of the nozzle bottom with the internal threaded groove, preventing the nozzle from loosening or shifting during high-pressure spraying. It also guarantees the coaxiality of the material outlet and air outlet channels, stabilizing the mixing ratio of the release agent and airflow, reducing maintenance costs, and extending the overall service life of the equipment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: Through three adjustment components, the output size, main air pressure, and atomization width range can be precisely controlled to meet the needs of different die-casting scenarios and have strong adaptability; and the dual air source spray with one inlet and two outlets, combined with detachable nozzles and atomizing caps, makes the spray more uniform and delicate, improves the coating quality of release agent, and optimizes the die-casting production process; and the combination of multiple channels and control switches ensures stable operation and facilitates operation and maintenance.

[0016] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0017] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0018] refer to Figures 1 to 4 As shown in the figure, the spray structure of a die-casting machine spray head provided by this utility model embodiment includes a spray head body 8. The output end of the spray head body 8 is equipped with a nozzle 1 and an atomizing cap 2. The nozzle 1 is provided with a material discharge channel and an air discharge channel inside. The top of the spray head body 8 is equipped with three adjustment components, namely a material discharge size adjustment switch 10 for adjusting the material discharge size, an atomization width adjustment switch 11 for adjusting the atomization width, and an air pressure adjustment switch 4 for adjusting the main air pressure. The output end of the spray head body 8 is also provided with a material inlet channel, an air inlet channel, and an air outlet channel, and the air inlet channel and the air outlet channel are connected, adopting a dual air source spray method with one inlet and two outlets.

[0019] The above solution enables multi-dimensional and precise control of the spraying process. The discharge size adjustment switch 10 can precisely control the amount of release agent according to the mold size and die-casting requirements, avoiding waste or insufficiency. The atomization width adjustment switch 11 facilitates flexible adjustment of the atomization range, adapting to mold surfaces of different shapes and sizes. The main air pressure adjustment switch 4 can adjust the atomization intensity in accordance with the characteristics of the release agent. Combined with the dual air source design of one inlet and two outlets, the airflow and release agent are mixed more thoroughly, ultimately achieving a significant improvement in the uniformity and fineness of the spray. This meets the atomization effect requirements of different die-casting processes, helps improve the coating quality of the release agent, and increases the efficiency of die-casting production.

[0020] Specifically, a water inlet piston switch 3 is installed on the side wall of the spray head body 8, and the bottom of the spray head body 8 is provided with a main airflow inlet 5, a fan-shaped wide and narrow air inlet 6, a feed inlet 7, and a switch control air inlet 9. All components work together to achieve the spraying function.

[0021] Using the above scheme, the water inlet piston switch 3 can flexibly control the water circuit opening and closing. The arrangement of the main airflow inlet 5 and the fan-shaped wide and narrow air inlets 6 makes the air source and material conveying path clear and orderly, reduces pipeline interference, and enables all components to work together to ensure stable airflow and smooth feeding, further ensuring the stability and reliability of the spraying process.

[0022] Specifically, the atomizing cap 2 is tightly fitted onto the outside of the nozzle 1, and an external threaded ring 12 is fixedly connected to the upper middle part of the spray head body 8. The bottom of the atomizing cap 2 is threaded onto the external threaded ring 12.

[0023] With the above solution, the atomizing cap 2 is tightly inserted into the outside of the nozzle 1 and threadedly connected to the external threaded ring 12. This ensures the stability of the movement path of the airflow and droplets during atomization and enables quick disassembly and assembly of the atomizing cap 2. It is convenient to replace the appropriate atomizing cap 2 according to different atomization needs. At the same time, the threaded connection has good sealing performance, which can prevent air pressure leakage from affecting the atomization effect and improve the versatility and maintenance efficiency of the equipment.

[0024] Specifically, an internal thread groove 13 is provided in the middle cavity of the spray head body 8 corresponding to the external thread ring 12, and the bottom thread of the nozzle 1 is inserted into the internal thread groove 13.

[0025] By adopting the above solution, the threaded engagement between the bottom of the nozzle 1 and the internal threaded groove 13 achieves a stable installation of the nozzle 1, ensuring that the nozzle 1 will not loosen or shift during high-pressure spraying, guaranteeing the coaxiality of the material outlet channel and the air outlet channel, stabilizing the mixing ratio of the release agent and the airflow, reducing maintenance costs, and extending the overall service life of the equipment.

[0026] The working principle of this utility model: In use, install nozzle 1 at the corresponding position of the output end of spray head body 8, and then assemble atomizing cap 2; connect each adjustment component in sequence, including discharge size adjustment switch 10, atomization width adjustment switch 11, and air pressure adjustment switch 4, ensuring secure installation and good sealing; the release agent enters the discharge channel of spray head body 8 through inlet 7, and compressed air enters the air intake channel through main airflow inlet 5 and fan-shaped width and width air inlet 6, forming an airflow environment; adjust the discharge amount of release agent by discharge size adjustment switch 10, control the atomization range by atomization width adjustment switch 11, adjust the main air pressure by air pressure adjustment switch 4, and control the air intake port 9 by water inlet piston switch 3. The structure primarily relies on air pressure to regulate airflow and liquid pathways. Under pneumatic or hydraulic pressure, the release agent is extruded through nozzle 1 and atomized into tiny droplets by the airflow under the action of the atomizing cap 2. These droplets are then sprayed out from the spray head. Due to the use of a dual air source (one inlet and two outlets) and precise adjustment, the spray is uniform and delicate, covering the mold surface. When maintenance or replacement of parts is required, nozzle 1 and the atomizing cap can be disassembled to clean and inspect the internal channels, ensuring the continuous and stable operation of the spray head.
