[0034] ​Specifically, when the type of pulp molded tableware products produced changes or the customer's order quantity for different products increases or decreases significantly, the device has higher durability and precision by processing the aluminum plate into a mold core with a specific shape and polishing treatment, thereby ensuring that the required products are produced. When the mold needs to be replaced during production, the operator can quickly replace it by rotating the counterbore screw 8, which separates it from the fixed block 7, allowing the female mold core one 5 and the female mold core two 6 to be easily removed. The female mold core one 5 and the female mold core two 6 are core components of the mold and are used to form different products. Through the polishing treatment of aluminum materials, not only can the surface finish of the mold be enhanced, reducing friction during production, but also the service life of the mold can be extended. In addition, when different types of products need to be mass-produced, the operator can freely combine the mold cores according to specific needs, allowing the working state of the device to be adjusted flexibly to adapt to the production needs of different products.

[0035] With reference to Figure 5 The cooling assembly includes a water tank 11 and a micro fan 12. The water tank 11 is fixedly connected to the side wall of the lower mold 2, and the micro fan 12 is arranged on one side of the water tank 11. The water tank 11 is filled with cooling water, and the micro fan 12 is used to cool the cooling water, thereby helping to reduce the temperature of the cooling water in the water tank 11, so that the cooling assembly can maintain stable cooling effect. The water tank 11 is fixedly connected with a water pump 13 at the top. The water pump 13 considers the flow and pressure requirements to ensure that the cooling water can be continuously pumped out of the water tank 11 and delivered to the key parts of the mold through the drainage pipe 16. The input end of the water pump 13 is fixedly connected to the inside of the water tank 11, and the output end of the water pump 13 is fixedly connected with the drainage pipe 16.

[0036] Specifically, during the continuous production of pulp molded tableware, when the mold temperature is too high due to frequent use, affecting the pulp forming effect and product quality, and reducing production efficiency, in this circulating cooling assembly, the water pump 13 as a key component, through its input end, the cooling water in the water tank 11 is pumped out and delivered to the inside of the drainage pipe 16. The role of the water pump 13 is to provide the necessary water flow power to ensure that the cooling water enters the subsequent components with appropriate flow. During the flow of cooling water in the drainage pipe 16, the heat generated during processing is quickly removed, playing a preliminary cooling role. The drainage pipe 16 has a good water flow channel to ensure that the flow rate of the cooling water is moderate to maximize the heat removal efficiency.

[0037] With reference to Figure 5The one end of the drainage pipe 16 is fixedly connected with a flow guide pipe 17, the flow guide pipe 17 is used for further guiding the cooling water, guiding the cooling water into the water tank 11 to carry out effective water cooling heat dissipation, the one end of the flow guide pipe 17 is fixedly connected with the connecting barrel 14, the connecting barrel 14 is fixedly connected in the water tank 11, the connecting barrel 14 is fixedly connected with a filter screen 15 in the inside, the filter screen 15 is fixed in the connecting barrel 14 through a clamping groove, the pore size of the filter screen 15 can effectively remove impurities such as silt, metal particles and the like in the cooling water, ensuring that the water entering the water tank 11 is clean, and the filter screen 15 is used for filtering the cooling water.

[0038] Specifically, when the cooling water flows along the drainage pipe 16, the cooling water is guided into the inside of the flow guide pipe 17, the flow guide pipe 17 further transports the cooling water to the connecting barrel 14, the flow guide pipe 17 plays a role in smooth transition in the water flow transmission process, ensuring that the water flow is not hindered into the connecting barrel 14, in the connecting barrel 14, the cooling water is filtered through the filter screen 15, the filter screen 15 has a precise pore size, which can effectively remove impurities, particles and other potential pollutants in the water, thereby ensuring the cleanliness of the cooling water, the role of the filter screen 15 is to prevent impurities from entering the circulating assembly, ensuring the long-term stable operation of the assembly, the filtered cooling water continues to flow into the inside of the water tank 11, completing the filtering and processing steps, in order to further ensure the working performance of the cooling water, the water tank 11 is provided with a micro fan 12, the micro fan 12 helps the cooling water in the water tank 11 to cool by forced air flow, further reduces the water temperature to maintain the low temperature state of the cooling water, prevents the cooling water from being too high to reduce the cooling efficiency.

[0039] Working principle: when the device is used, the aluminum plate is processed into a die with a specific shape and polished, when replacement operation is needed, the operator rotates the fixed block 7, the fixed block 7 is rotated out of the inside of the counterbore screw 8, thereby realizing the role of quickly disassembling the concave die one 5 and the concave die two 6, when batch production of different products is needed, the operator freely combines the dies, and the working state of the equipment can be adjusted according to the actual use, in the processing process, the cooling water in the water tank 11 is pumped out through the input end of the water pump 13 and is transported into the inside of the drainage pipe 16, the cooling water flows in the drainage pipe 16, thereby quickly taking away the heat generated during processing, the cooling water flows into the inside of the flow guide pipe 17 through the guidance of the drainage pipe 16, thereby further guiding the cooling water into the connecting barrel 14 through the flow guide pipe 17, the cooling water is filtered through the filter screen 15 in the connecting barrel 14, after the filtering is completed, the cooling water flows into the inside of the water tank 11, the cooling water is cooled by the micro fan 12 arranged on the outer wall of the water tank 11, ensuring the working performance of the cooling water, thereby realizing the role of circulating cooling.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
