[0002] Currently, hot runner technology is mainly used for electronic cigarette mouthpiece molds. Its advantages include no waste during production, short molding cycle, high efficiency, low pressure loss, and low product defect rate. However, hot runner technology has high requirements for materials and processing precision, and the mold cost is relatively high. In addition, the design of electronic cigarette mouthpiece molds needs to consider the flow channel balance, cooling balance, and the rationality of mold materials to ensure the use of the mold.
[0003] Electronic cigarette mouthpiece molds typically employ traditional cooling water channel designs, which are insufficient in terms of cooling efficiency and uniformity. This is especially true in deep-cavity molds, where the cooling water channels are difficult to machine, resulting in poor cooling performance and impacting molding cycle time and product quality.
[0004] Therefore, a multi-row electronic cigarette mouthpiece mold is proposed to address the above problems. Utility Model Content
[0005] To overcome the shortcomings of existing technologies, this paper addresses the problem of the traditional cooling water channel design commonly used in electronic cigarette mouthpiece molds, which suffers from deficiencies in cooling efficiency and uniformity. This is particularly true in deep-cavity molds, where the cooling water channels are difficult to machine, leading to poor cooling performance and impacting molding cycle time and product quality.

[0013] The advantages of this utility model are:
[0014] 1. This utility model, through the inclusion of an extrusion component, achieves efficient, flexible, and stable production results with its multi-row electronic cigarette mouthpiece mold design, achieved through ingenious structural layout and component coordination. Firstly, the extrusion component inside the mold body adopts an elastic structure design. The internal mold is connected to the cover plate via springs. This structure allows the internal mold to elastically expand and contract according to the material filling during the molding process, effectively avoiding product defects caused by uneven material filling and improving product molding quality and consistency. Simultaneously, the evenly spaced spring arrangement ensures uniform force distribution on the internal mold in all directions, further enhancing the stability of the molding effect. Furthermore, the integrated design of the internal mold and slider, along with the sliding structure design, not only enhances the structural stability of the mold but also facilitates rapid adjustment of the internal mold's position during production, improving its flexibility and adaptability to better meet diverse production needs. This structural design improves production efficiency while reducing production costs, demonstrating high practicality and innovation, and providing a more efficient and reliable solution for electronic cigarette mouthpiece production.
[0015] 2. This utility model, by incorporating a bottom cooling component, employs a highly efficient and stable circulating cooling structure for the cooling system of this multi-row electronic cigarette mouthpiece mold. Through the interconnection of a micro water pump, outlet pipe, cooling pipe, inlet pipe, cooling tank, and connecting pipes, the coolant circulates continuously. This design not only ensures continuous and uniform cooling of the mold, effectively shortening the molding cycle and improving production efficiency, but also enhances the durability and service life of the cooling pipes by coating the inner walls with a corrosion-resistant varnish material. The entire cooling system is compact and rationally laid out, stably maintaining the mold temperature during production, ensuring product quality stability, while also reducing maintenance costs and improving the overall performance and reliability of the mold.
[0016] 3. This utility model, through the inclusion of a top cooling assembly, forms a highly efficient cooling system for this multi-row electronic cigarette mouthpiece mold via a connected structure of an inlet pipe, a heat-conducting pipe, and an outlet pipe. The heat-conducting pipe employs an "S"-shaped design, a unique structural layout that significantly increases the flow path and residence time of the coolant within the mold, thereby improving cooling efficiency. This allows the mold to dissipate heat more quickly during the molding process, effectively shortening the molding cycle and increasing production efficiency. Simultaneously, the control valve design on the outer wall of the inlet pipe allows for flexible adjustment of the coolant flow rate according to actual production needs, further optimizing the cooling effect and ensuring stable operation of the mold under different production conditions. Overall, this top cooling assembly design not only improves cooling performance but also enhances the mold's adaptability and ease of operation, providing a strong guarantee for the high-quality production of electronic cigarette mouthpieces.

[0027] Please see Figure 4The multi-row electronic cigarette mouthpiece mold shown includes a bottom cooling assembly 2 comprising a micro water pump 201. A liquid outlet pipe 202 is fixedly connected to the side of the micro water pump 201, and a cooling pipe 203 is fixedly connected to the end of the liquid outlet pipe 202.

[0028] Please see Figure 5 The multi-row electronic cigarette mouthpiece mold shown includes a top cooling assembly 3 comprising a water inlet pipe 303, a control valve 304 fixedly connected to the outer wall of the water inlet pipe 303, a heat-conducting pipe 302 fixedly connected to the end of the water inlet pipe 303, and a water outlet pipe 301 fixedly connected to the end of the heat-conducting pipe 302; the water inlet pipe 303 and the water outlet pipe 301 form a communication structure through the heat-conducting pipe 302, and the heat-conducting pipe 302 is set in an "S" shape.
[0029] Working principle: First, check the assembly and sealing of the mold body 4 and each component. Confirm that the buckle 102 on the side of the cover plate 101 in the extrusion assembly 1 is stably engaged with the corresponding card box 103 to ensure the relative position of the cover plate 101 and the mold body 4 is stable during the subsequent extrusion process. At the same time, pre-treat the cooling system by adding sufficient cooling medium to the cooling box 205 of the bottom cooling assembly 2. Check that the circuit consisting of the micro water pump 201, the outlet pipe 202, the cooling pipe 203, the inlet pipe 204 and the connecting pipe 206 is unobstructed. Ensure that the anti-corrosion coating of the raw paint material on the inner wall of the cooling pipe 203 is undamaged. At the same time, confirm that the control valve 304 on the outer wall of the water inlet pipe 303 in the top cooling assembly 3 is closed to prevent premature leakage of the cooling medium. After the mold is started, the extrusion molding stage begins immediately. The external driving force is precisely applied to the cover plate 101 of the extrusion assembly 1. The cover plate 101 is positioned by the engagement of the buckle 102 and the card box 103, effectively preventing lateral displacement during extrusion. Since the internal mold 106 forms an elastic structure with the cover plate 101 through the springs 105, and the springs 105 are arranged at equal intervals inside the cover plate 101, the driving force transmitted by the cover plate 101 is buffered and evenly distributed through the elastic deformation of the springs 105, and acts smoothly on the internal mold 106, thus avoiding instantaneous impact. The impact force does not damage the internal mold 106, but ensures that the force is evenly distributed in all areas of the internal mold 106. At the same time, since the internal mold 106 and the slider 104 are integrated, and the internal mold 106 forms a sliding structure with the mold body 4 through the slider 104, the internal mold 106 will slide smoothly downward along the preset slide rail of the mold body 4 under the action of the driving force, and accurately embed into the multiple rows of mold cavities inside the mold body 4, extruding and shaping the cigarette nozzle material in the mold cavity, ensuring the density and dimensional uniformity of the multi-row cigarette nozzle molding.Simultaneously with the extrusion molding process, a dual cooling system is activated to achieve all-round constant temperature cooling of the upper and lower areas of the mold cavity: In the bottom cooling component 2, the micro water pump 201 is powered on and draws cooling medium from the cooling tank 205 through the connecting pipe 206, and delivers it to the cooling pipe 203 through the liquid outlet pipe 202. Since the micro water pump 201 and the cooling pipe 203 form a connected structure through the liquid outlet pipe 202, and the cooling pipe 203 and the cooling tank 205 form a connected structure through the liquid inlet pipe 204, and the cooling tank 205 and the micro water pump 201 form a complete connected loop through the connecting pipe 206, when the cooling medium flows in the cooling pipe 203, it can fully absorb the molding heat transferred from the bottom of the mold body 4, while the varnish coating... The cooling medium effectively isolates itself from the corrosion of the cooling pipe 203. After absorbing heat, the cooling medium flows back to the cooling tank 205 through the liquid inlet pipe 204 for cooling, forming a continuously circulating bottom cooling loop. At the same time, the control valve 304 of the top cooling component 3 is opened, and the cooling medium enters the heat conduction pipe 302 through the water inlet pipe 303. Because the water inlet pipe 303 and the water outlet pipe 301 are connected through the heat conduction pipe 302, and the heat conduction pipe 302 is set in an "S" shape, the contact area with the internal mold 106 is greatly increased, which can quickly absorb the heat from the internal mold 106 and the top of the mold cavity, improving the cooling uniformity. After absorbing heat, the cooling medium is finally discharged through the water outlet pipe 301, completing the top cooling cycle. The synergistic operation of the dual cooling system can quickly reduce the temperature of the nozzle in the mold cavity, effectively shorten the molding cycle, and reduce deformation defects of the nozzle caused by uneven cooling. After the cigarette holder is formed, the mold enters the demolding stage. The direction of the external driving force changes, causing the cover plate 101 to move upward, and the buckle 102 disengages from the card box 103. Under the action of the elastic restoring force, the spring 105 pushes the internal mold 106 to return to its original position upward. At the same time, the internal mold 106 moves smoothly upward along the slide rail of the mold body 4 via the slider 104, simultaneously ejecting the formed multiple rows of cigarette holders from the mold cavity, achieving convenient demolding. Throughout the entire process, the precise and coordinated operation of each component not only ensures the forming quality of the cigarette holder but also improves production efficiency. Furthermore, the protective design of each structure extends the service life of the mold.
