[0032] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0033] This utility model provides an injection mold for an electronic cigarette casing, including a fixed mold 12 and a movable mold 11. The fixed mold 12 includes a rear template 121 and a rear mold core 1211 connected within the rear template 121. The movable mold 11 includes a front template 111 and a mold core assembly 113 located within the front template 111 for cooperating with the rear mold core 1211 to form an injection mold cavity 1136 for the electronic cigarette casing. The mold core assembly 113 includes a first slider 1131, a second slider 1132, a third slider 1133, and a fourth slider 1134. The third slider... Slider 1133 and fourth slider 1134 are located between first slider 1131 and second slider 1132, respectively. Mold core assembly 113 is also provided with a glue inlet channel 1135. Molten glue flows from the glue inlet channel 1135 through the side walls of first slider 1131, second slider 1132, and fourth slider 1134 sequentially into the mold cavity. Fourth slider 1134 is located at the bottom position after the cigarette shell is formed. When injection molding the electronic cigarette shell, firstly, moving mold 11 and fixed mold 12 close, and front mold plate 111 and rear mold plate 1132 close together. 21. Simultaneously, the mold core assembly 113 and the rear mold core 1211 are bonded together to form a mold cavity 1136 for injection molding of the smoke shell. The first slider 1131, the second slider 1132, the third slider 1133, and the fourth slider 1134 are respectively located on the upper periphery of the rear mold core 1211. When the molten glue enters the injection channel 1135, the injection channel 1135 passes through the first slider 1131 and the second slider 1132 and flows into the fourth slider 1134. The molten glue flows from the side wall of the fourth slider 1134. The molten adhesive is injected into the mold cavity 1136, where it forms the shape of a cigarette shell. After the cigarette shell is injection molded, the moving mold 11 separates from the fixed mold 12. The first slider 1131, the second slider 1132, the third slider 1133, and the fourth slider 1134 all separate from the lower mold core. After the fourth slider 1134 separates from the lower mold core, the molten adhesive in the fourth slider 1134 breaks away from the cigarette nozzle in the mold cavity 1136. The sprue of the cigarette shell is located at the bottom of the cigarette shell, making the cigarette shell more aesthetically pleasing.

[0034] Please refer to Figure 7 The mold core assembly 113 is also provided with symmetrical first inclined guide pillars 1141 and symmetrical second inclined guide pillars 1142. The symmetrical first inclined guide pillars 1141 are located on the first slider 1131 and the second slider 1132 respectively, and the symmetrical second inclined guide pillars 1142 are located on the third slider 1133 and the fourth slider 1134 respectively. The first inclined guide pillars 1141 are used to move the first slider 1131 and the second slider 1132 away from the lower mold core, and the second inclined guide pillars 1142 are used to move the third slider 1133 and the fourth slider 1134 away from the lower mold core, thereby facilitating the demolding of the smoke shell after injection molding.

[0035] A fixing plate 114 is also provided inside the front template 111. Symmetrical first inclined guide pillars 1141 and symmetrical second inclined guide pillars 1142 are respectively fixed on the fixing plate 114. The fixing plate 114 is used to fix the first inclined guide pillars 1141 and the second inclined guide pillars 1142. When the moving mold 11 moves away from the fixed mold 12, the fixing plate 114 drives the first inclined guide pillars 1141 and the second inclined guide pillars 1142 to move. When the first inclined guide pillar 1141 moves, due to the first inclined guide pillar 1142 moving... 141 is inclined. During the movement of the first inclined guide post 1141, it facilitates the movement of the first slider 1131 and the second slider 1132 away from the lower mold core. At the same time, during the movement of the second inclined guide post 1142, it facilitates the movement of the third slider 1133 and the fourth slider 1134 away from the lower mold core, thus avoiding damage to the surface of the formed smoke shell caused by the movement of the first slider 1131, the second slider 1132, the third slider 1133, and the fourth slider 1134.

[0036] The front template 111 is also equipped with a first shovel 115 located on one side of the first slider 1131 and the second slider 1132 respectively. The first shovel 115 is used to limit the first slider 1131 and the second slider 1132. When the moving mold 11 and the fixed mold 12 are attached, the first shovel 115 on the first slider 1131 side is attached to the first slider 1131, and the first shovel 115 on the second slider 1132 side is attached to the second slider 1132. During the glue injection process, the product can effectively prevent the first slider 1131 and the second slider 1132 from loosening, thereby effectively ensuring that the glued smoke shell meets the standards.

[0037] The front template 111 is also equipped with a symmetrical second shovel 116. The third slider 1133 and the fourth slider 1134 are both located in the second shovel 116. The second shovel 116 is used to limit the third slider and the fourth slider 1134 to prevent the third slider 1133 and the fourth slider 1134 from becoming loose during the glue injection process.

[0038] The second shovel 116 includes a first limiting block and a second limiting block located on one side of the first limiting block. A limiting channel is formed between the first limiting block and the second limiting block for the movement of the third slider 1133 and the fourth slider 1134. The limiting channel is used to limit the movement direction of the third slider 1133 and the fourth slider 1134. During the demolding and mold closing process, the third slider 1133 and the fourth slider 1134 move in the defined direction, thereby enabling the third slider 1133 and the fourth slider 1134 to be precisely demolded and closed.

[0039] Both the first slider 1131 and the second slider 1132 are provided with water channels for cooling the smoke shell. The water channels are used to cool the smoke shell after injection molding, thereby accelerating the formation efficiency of the smoke shell and improving the efficiency of injection molding of the smoke shell.

[0040] The moving mold 11 is also provided with a nozzle 112 for injecting glue. The nozzle 112 is connected to the glue injection channel 1135. The nozzle 112 is used to connect the external component for melting glue, so that the melted glue can smoothly enter the nozzle 112 and enter the glue injection channel 1135.

[0041] The fixed mold 12 is also provided with an ejection assembly 124 for ejecting the smoke shell. The ejection assembly 124 is used to eject the smoke shell after injection molding, so as to reduce manual handling of the smoke shell after injection molding and further improve the efficiency of injection molding.

[0042] The fixed mold 12 also includes a base plate 122 and square irons 123 located on both sides of the base plate 122. The base plate 122, square irons 123 and rear template 121 form a cavity for the ejector assembly 124 to move. The base plate 122 is used to fix the square irons 123 and the rear template 121 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 smoke shell.

[0043] Working principle:

[0044] When the cigarette shell is injection molded, the moving mold 11 and the fixed mold 12 close together, the front mold plate 111 and the rear mold plate 121 are fitted together, and the mold core assembly 113 is fitted together with the rear mold core 1211. The first slider 1131, the second slider 1132, the third slider 1133, the fourth slider 1134, and the rear mold core 1211 form a mold cavity 1136 for injection molding the cigarette shell. When the molten adhesive enters from the nozzle 112 and enters the injection channel 1135, the molten adhesive passes through the first slider... Slider 1131 and Slider 1132 enter the fourth slider 1134. The molten adhesive entering the fourth slider 1134 flows from the side wall of the fourth slider 1134 into the mold cavity 1136. After the molten adhesive has filled the entire mold cavity 1136, cooling water enters the water channels in the first slider 1131 and the second slider 1132 to cool the molten adhesive in the mold cavity 1136, thereby accelerating the molding of the smoke shell. When the injection time is reached, the moving mold 11 and the fixed mold 12... Separation occurs when the front mold plate 111 separates from the rear mold plate 121. Due to the action of the fixing plate 114, the fixing plate 114 moves, causing the first inclined guide post 1141 and the second inclined guide post 1142 to move. When the first inclined guide post 1141 moves, it drives the first slider 1131 and the second slider 1132 to move. The second inclined guide post 1142 moves to the third slider 1133 and the fourth slider 1134, so that the mold core assembly 113 and the rear mold core 1211 separate. During the movement of the fourth slider 1134, the sprue material located in the fourth slider 1134 separates from the smoke shell, thereby avoiding manual cleaning of the sprue again. Finally, the smoke shell in the lower mold core of the ejector assembly 124 is ejected, saving manual operation. Since the fourth slider 1134 is the bottom of the injection molded smoke shell, and the outlet of the injection channel 1135 is located on the side wall of the fourth slider 1134, the sprue break of the smoke shell is located at the bottom of the smoke shell, making the injection molded smoke shell more aesthetically pleasing.

[0045] 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.
