[0035] This utility model provides an injection mold for a cigarette holder, including a movable mold 11 and a fixed mold 12. The movable mold 11 includes a front mold plate 111 and an upper mold core 114 and a manifold 115 located on both sides of the front mold plate 111. The fixed mold 12 includes a rear mold plate 122 and a lower mold core connected to the rear mold plate 122 and capable of fitting with the upper mold core 114. The upper mold core 114 and the lower mold core are closed to form a molding cavity for injection molding the cigarette holder. A first groove 1111 for placing the manifold 115 is provided on the side of the front mold plate 111 away from the upper mold core 114. A first flow channel 1112 and a second flow channel 1113 located on one side of the first flow channel 1112 and not communicating with it are provided in the first groove 1111. The second flow channel 1113 communicates with the upper mold core 114. A third flow channel 1151 is provided on the manifold 115. The two ends of the third flow channel 1151 communicate with the first flow channel 1112 and the second flow channel 1113 respectively. The third flow channel 1151 is located above the first flow channel 1112 and the second flow channel 1113. When the injection mold is used for injecting the cigarette nozzle, First, the moving mold 11 and the fixed mold 12 are closed, the front mold plate 111 and the rear mold plate 122 are fitted together, and the upper mold core 114 and the lower mold core are fitted together. The fitting of the upper mold core 114 and the lower mold core forms the molding cavity for injection molding. When the molten adhesive enters the runner from the moving mold 11, the molten adhesive enters the first runner 1112. Since the first runner 1112 and the second runner 1113 are not connected, while the two ends of the third runner 1151 are connected to the first runner 1112 and the second runner 1113, and the third runner 1151 is located in the first runner. Above the first channel 1112 and the second channel 1113, when the melted adhesive from the first channel 1112 enters the third channel 1151, it is necessary to increase the extrusion pressure of the melted adhesive to transport it from the first channel 1112 to the third channel 1151. While increasing the extrusion pressure, it can effectively reduce air bubbles in the melted adhesive, thereby transporting the bubble-reduced melted adhesive to the second channel 1113. The melted adhesive then flows into the molding cavity through the second channel 1113, effectively reducing air bubbles in the product and making the mouthpiece more aesthetically pleasing.

[0036] The first groove 1111 also contains symmetrical fourth flow channels 1114, which are located at both ends of the first flow channel 1112 and communicate with it. The fourth flow channels 1114 are perpendicular to the first flow channel 1112. Multiple second flow channels 1113 are provided, each located at one end of the fourth flow channel 1114. Multiple third flow channels 1151 are provided, with both ends of each third flow channel 1151 communicating with the fourth flow channel 1114 and the second flow channels 1113. The symmetrical fourth flow channels 1114... 114 is located at both ends of the first flow channel 1112, and the fourth flow channel 1114 is connected to the third flow channel 1151. When the molten adhesive enters the first flow channel 1112, the molten adhesive in the first flow channel 1112 flows to both ends of the first flow channel 1112 and enters the fourth flow channel 1114. The molten adhesive then enters the third flow channel 1151 through the fourth flow channel 1114, and then enters the second flow channel 1113 through the third flow channel 1151. By setting the fourth flow channel 1114, multiple cigarette holders can be injection molded at the same time, thereby increasing the efficiency of injection molding cigarette holders.

[0037] Both ends of the second flow channel 1113 are provided with flow channel openings that communicate with the upper mold core 114. The molten adhesive enters the molding cavity through the flow channel openings at both ends of the second flow channel 1113, further increasing the number of injection molded cigarette nozzles and further increasing the efficiency of cigarette nozzle production.

[0038] The moving mold 11 also includes a nozzle 113, which passes through the manifold 115 and is connected to the first flow channel 1112. The melted glue enters the moving mold 11 through the nozzle 113 and flows into the first flow channel 1112, which can effectively ensure that the melted glue enters the first flow channel 1112.

[0039] The moving mold 11 is also provided with a panel 112 for fixing the nozzle 113 and the front template 111. The panel 112 is used to fix the nozzle 113 and the front template 111, so that the nozzle 113, the front template 111 and the panel 112 form a whole.

[0040] Both the upper mold core 114 and the lower mold core are provided with water channels 13. The water channels 13 are used to accelerate the cooling of the molten adhesive entering the upper mold core 114 and the lower mold core, thereby accelerating the molding efficiency of the cigarette nozzle in the molding cavity.

[0041] A second groove is provided on the side of the front template 111 near the lower mold core, and the upper mold core 114 is located in the second groove to reduce the volume of the moving mold 11. At the same time, when the front template 111 and the rear template 122 are attached together, it is also convenient for the upper mold core 114 and the lower mold core to be attached together.

[0042] A third groove is provided on the side of the rear template 122 near the upper mold core 114. The lower mold core is located in the third groove to reduce the volume of the fixed mold 12. At the same time, when the rear template 122 and the front template 111 are attached together, it is also convenient for the lower mold core and the upper mold core 114 to be attached together.

[0043] The fixed mold 12 is also provided with an ejector assembly 124 for ejecting the cigarette nozzle. The ejector assembly 124 is used to eject the injection-molded cigarette nozzle, thereby eliminating the need for manual handling and speeding up the injection molding process.

[0044] The fixed mold 12 is also provided with a base plate 121 and square irons 123 located on both sides of the base plate 121. The base plate 121, square irons 123 and lower mold core form a cavity for the ejector assembly 124 to move. The base plate 121 is used to fix the square irons 123 and the rear template 122 into a whole. The ejector assembly 124 is located in the cavity, which facilitates the movement of the ejector assembly 124 in the fixed mold 12, thereby ejecting the formed cigarette nozzle.

[0045] Working principle:

[0046] During injection molding of the cigarette holder, the moving mold 11 and the fixed mold 12 are closed together, so that the front mold plate 111 and the rear mold plate 122 are fitted together. After the front mold plate 111 and the rear mold plate 122 are fitted together, the upper mold core 114 and the lower mold core are also fitted together. The upper mold core 114 and the lower mold core are fitted together to form the molding cavity of the cigarette holder. Both ends of the second runner 1113 are provided with runner openings that communicate with the molding cavity. Each runner opening provides molten glue for a separate cigarette holder. The molten glue enters the first runner 1112 from the nozzle 113. The molten glue entering the first runner 1112 flows from both ends of the first runner 1112 and enters the fourth runner 1114 from both ends of the first runner 1112. The molten glue entering the fourth runner 1114 enters the third runner 1151. Since the height of the third runner 1151 is higher than that of the fourth runner 1114 and the second runner 1113, it is necessary to increase the extrusion pressure of the molten glue. The molten adhesive in the fourth channel 1114 can be transported to the third channel 1151, which increases the extrusion pressure of the molten adhesive and effectively reduces air bubbles in the molten adhesive. The molten adhesive in the fourth channel 1114 enters the second channel 1113 through the third channel 1151. The molten adhesive in the second channel 1113 enters the molding cavity through the flow outlets at both ends of the second channel 1113 for molding. After the molding cavity is filled with molten adhesive, cooling water enters the water channels 13 in the upper mold core 114 and the lower mold core to cool and mold the molten adhesive in the molding cavity. After the mouthpiece is molded, the moving mold 11 and the fixed mold 12 separate. The ejection assembly 124 of the fixed mold 12 ejects the mouthpiece for the next injection molding. Through the diversion of the third channel 1151, which is higher than the fourth channel 1114 and the second channel 1113, air bubbles in the molten adhesive can be effectively reduced, thus making the injection molded mouthpiece more aesthetically pleasing.

[0047] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
