[0040] The following is for reference. Figures 1-5 A graphite release agent spraying apparatus is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0041] like Figures 1-4 As shown, a graphite release agent spraying device includes an oil tank 100, a stirring mechanism, and a graphite pump 130.

[0042] The oil tank 100 is used to store graphite oil; the stirring mechanism includes a stirring paddle 110 located in the oil tank 100 and a stirring motor 120 driving the stirring paddle 110; multiple graphite pumps 130 are provided, each with a slide rail 140 and a piston rod 150 cooperating with the slide rail 140. A pneumatic chamber 160 and an oil outlet chamber 170 are sequentially arranged on the slide rail 140. A first piston 180 cooperating with the pneumatic chamber 160 and a second piston 190 cooperating with the oil outlet chamber 170 are provided on the piston rod 150. A first air port 200 and a second air port 210 communicating with an air compressor (not shown in the figure) are respectively provided on both sides of the pneumatic chamber 160. The oil outlet chamber 170… The end is provided with an oil inlet 220 and an oil outlet 230. The oil inlet 220 is connected to the oil tank 100 through a one-way valve (the one-way valve is not shown in the figure). The oil outlet 230 is provided with an oil outlet pipe connected to the nozzle (the oil outlet pipe and nozzle are not shown in the figure). The piston rod 150 is driven to reciprocate by alternating air intake on both sides of the pneumatic chamber 160, so that the second piston 190 forms a quantitative delivery pressure in the oil outlet chamber 170, thereby spraying graphite oil from the nozzle. One end of the piston rod 150 extends to the outside of the slide 140 and is provided with an adjustable limiting cylinder 240, which is used to limit the stroke of the piston rod 150 and thus adjust the amount of graphite oil sprayed. It should be noted that a sealing ring is required at the outlet of the slide 140.

[0043] In use, graphite oil and additives are added to the oil tank 100, the stirring mechanism is started, and the stirring motor 120 drives the stirring to rotate, so that the graphite oil and additives are evenly mixed. The amount of graphite oil sprayed is adjusted by adjusting the limit cylinder 240. Then the air compressor is started to alternately supply air to both sides of the pneumatic chamber 160. The forward stroke gas enters from the first air hole 200 and pushes the first piston 180 and piston rod 150 to move towards the oil outlet chamber 170. The second piston 190 compresses the oil outlet chamber 170, and the graphite oil is sprayed out from the nozzle under high pressure through the oil outlet pipe. The reverse reset gas is switched to the second air hole 210 to push the piston rod 150 to reset. The oil outlet chamber 170 draws in new oil from the oil tank 100 through the oil inlet hole 220. Throughout the process, the one-way valve plays the role of unidirectional movement of graphite oil in the oil inlet hole 220. The piston rod 150 is driven to reciprocate by the alternating air intake of the pneumatic chamber 160, and the piston stroke is adjusted by the limiting cylinder 240 to achieve precise quantitative delivery of graphite oil, ensuring uniform and controllable spraying amount; the output pressure of the graphite pump 130 is increased, effectively avoiding nozzle clogging; the stirring mechanism fully integrates the graphite oil and additives, improving the performance of the release agent; after the overall structure is optimized, the coating on the mold surface is uniform, significantly improving demolding efficiency and product quality.

[0044] Specifically, such as Figure 1 and Figure 2As shown, the system also includes a frame 250, an oil tank 100 located on top of the frame 250, and a graphite pump 130 located below the oil tank 100. The oil tank 100 on top of the frame 250 and the graphite pump 130 below form a compact vertical layout, saving space and facilitating maintenance. Gravity-assisted oil flow reduces pumping resistance and improves system stability. Specifically, the frame 250 has two mounting plates 260 below the graphite pump 130, and the graphite pump 130 is sequentially mounted on the mounting plates 260. The layered mounting of the graphite pump 130 on the double-layered plates of the frame 250 achieves a modular layout, facilitating multi-pump collaborative operation and independent maintenance, while reducing vibration interference and extending equipment lifespan. Furthermore, a stirring motor 120 is vertically mounted on the top surface of the oil tank 100, and the stirring motor 120 is connected to the stirring paddle 110 inside the oil tank 100 via its output shaft. The stirring motor 120 is vertically arranged on the top surface of the oil tank 100, directly driving the stirring paddle 110. It has high transmission efficiency and good sealing performance, avoiding oil leakage and ensuring uniform mixing.

[0045] It should be noted that the top surface of the oil tank 100 is equipped with a graphite oil filling port 270. This port facilitates rapid replenishment of graphite oil, and a sealing cap is required to prevent impurities from entering and maintain the cleanliness of the inside of the oil tank 100. Additionally, the top surface of the oil tank 100 is equipped with an oil level alarm gauge 280 that extends into the tank. This built-in gauge monitors the oil level in real time, promptly alerting the user to replenish graphite oil and preventing spraying interruptions due to insufficient oil, thus ensuring continuous production. Similarly, the side surface of the oil tank 100 is equipped with an oil level observation gauge 290. This side gauge provides a clear display of the liquid level, facilitating quick manual checking of the oil level and reducing the complexity of equipment monitoring.

[0046] It is understandable that, such as Figure 1 As shown, the graphite pump 130 is equipped with a graphite oil output switch 300. The output switch of the graphite pump 130 precisely controls the oil circuit, enabling rapid response to start and stop of spraying, reducing oil waste and improving operational flexibility.

[0047] It is worth mentioning that, such as Figure 4 and Figure 5As shown, the piston rod 150 extends to one end of the slide rail 140 and has an external thread, while the limiting cylinder 240 has an internal thread that mates with the external thread. The threaded engagement structure between the piston rod 150 and the limiting cylinder 240 enables fine-tuning of the stroke, providing high adjustment accuracy and secure locking, ensuring long-term stability of the quantitative delivery parameters. Specifically, the upper side of the limiting cylinder 240 has a locking cap 310. The locking cap 310 has a through hole 320 in its center for the piston rod 150 to pass through. Connecting portions 330 on both sides of the locking cap 310 connect to the limiting cylinder 240, forming a locking groove 340 between the two connecting portions 330. The end face of the locking cap 310 has bolt holes 350 for accommodating bolts connected to the limiting cylinder 240, causing the locking groove 340 to contract and clamp the piston rod 150 within the through hole 320. The locking gland 310 clamps the piston rod 150 by shrinking the locking groove 340 with bolts, preventing the limit cylinder 240 from shifting relative to the piston rod 150, ensuring the reliability of the fixed position after stroke adjustment, and reducing the frequency of maintenance.

In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
