Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a molding mold for an electronic cigarette shell. Background Technology

[0002] Currently, molds are tools used to create shaped objects. These tools are composed of various different parts. Molds mainly achieve the processing of the shape of objects by changing the physical state of the material being molded, and are known as the "mother of industry." Furthermore, as the concept of healthy living becomes more popular, in order to ensure their own health and the feelings of others, some smokers have begun to choose e-cigarettes. With the continuous increase in such users, the actual scope of use and application scenarios of e-cigarettes are constantly expanding. Moreover, the non-combustible nature of e-cigarettes has further expanded the scope of use and application scenarios of e-cigarettes. At the same time, the application of molds is indispensable in the production process of e-cigarettes.

[0003] Existing electronic cigarette casing processing involves injection molding the outer shell and mouthpiece separately using injection molds. Other components are then manually assembled inside the outer shell before the mouthpiece is attached to it. However, this assembly process is complex, and since the outer shell is assembled from two separate casings, two injection molds are required, increasing the manufacturing cost of the electronic cigarette casing, resulting in poor usability and limited applicability.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide an electronic cigarette shell molding mold. Through the design of each component, it realizes the integrated injection molding of the mouthpiece and the shell, so as to facilitate the subsequent assembly operations between the shell and various components, thereby improving the production efficiency and quality stability of the product, ensuring the yield rate of injection molded parts, with good usability and wide applicability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electronic cigarette casing molding die includes an upper mold, a lower mold, and a molding slider mechanism; wherein:

[0008] The forming slider mechanism includes forming sliders, inclined guide pillars, and elastic reset components. The lower mold has a core. Four forming sliders are provided, each movably mounted on the lower mold and arranged around the four sides of the core. Three adjacent forming sliders have a first forming surface on the side closest to the core. The core has a second forming surface, with a mouthpiece forming portion at the upper end of the second forming surface. Another forming slider has an extension portion extending towards the core, with a third forming surface on the side of the extension portion closest to the core. The core extends accordingly. The upper mold is provided with a first groove, which passes through the second molding surface. The extension passes through the first groove, and the third molding surface extends out of the first groove and is flush with the second molding surface. The inclined guide post is used to drive the molding slider to move. The upper mold has a cavity, and the cavity is provided with a fourth molding surface. The inclined guide post is provided on the upper mold and is arranged around the four sides of the cavity corresponding to the four molding sliders. The two ends of the elastic reset member act on the molding slider and the lower mold respectively. When the upper mold and the lower mold are closed, the first molding surface, the second molding surface, the third molding surface and the fourth molding surface form an injection mold cavity.

[0009] As a preferred embodiment, the fourth forming surface is provided with a mouthpiece forming block for forming a mouthpiece opening, and the mouthpiece forming part is provided with a groove that matches the mouthpiece forming block. The mouthpiece forming block matches the groove, and a mouthpiece forming cavity is formed between the outer wall of the mouthpiece forming block and the inner wall of the groove.

[0010] It also includes a gating system, which is located inside the upper mold. The gating system includes a gating channel and a branch channel connecting the gating channel. The upper end of the gating channel penetrates the upper mold. The branch channel is connected to the mouthpiece forming block of the cavity. The mouthpiece forming block has an inlet on its outer side for the rubber material to flow into the injection mold cavity. The inlet is located at the upper part of the groove.

[0011] As a preferred embodiment, the injection port is located on a side away from the first molding surface.

[0012] As a preferred embodiment, the lower mold is further provided with an ejection mechanism, which includes an ejector rod and a drive device for driving the ejector rod to rise and fall. The ejector rod is movably mounted on the lower mold, and its upper end passes through the core and protrudes outside the core. Several ejector rods are provided, and the ejector rods are arranged at intervals around the periphery of the core. One ejector rod is located at the center of the groove. The extension is provided with a vertically penetrating clearance groove, which extends along the length of the extension. The ejector rod passes through the clearance groove of the extension and protrudes out of the core.

[0013] As a preferred embodiment, the lower end of the mouthpiece forming block is provided with a through hole forming part, and the upper end of the top rod located in the groove is provided with a positioning groove that matches the through hole forming part. The through hole forming part is adapted to the positioning groove, and the lower end of the mouthpiece forming block contacts the upper end of the top rod located in the groove.

[0014] As a preferred embodiment, the through-hole forming part is arranged in a gradually decreasing shape from top to bottom, and correspondingly, the positioning groove is arranged in a gradually decreasing shape from top to bottom.

[0015] As a preferred embodiment, each of the four forming sliders is provided with a displacement cavity for contacting the inclined guide post.

[0017] As a preferred embodiment, limiting grooves are provided on both sides of the second slide groove, and protrusions are provided on the forming slider corresponding to the limiting grooves, the protrusions being constrained by the limiting grooves.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly achieves the one-piece injection molding of the mouthpiece and the shell by designing each component and using the mold closing of the upper and lower molds to fit the first to fourth molding surfaces and form an injection mold cavity. This facilitates the subsequent assembly operation between the shell and various components, thereby improving the production efficiency and quality stability of the product and ensuring the yield rate of the injection molded parts. With the setting of the third molding surface, corresponding concave and convex structures can be set on the third molding surface according to the assembly structure of the inner wall of the shell, thereby meeting the molding use of different models, with good usability and wide applicability.

[0019] Furthermore, the ejection mechanism utilizes the positional design of five ejector pins to facilitate the ejection of the injection molded part from the lower mold after molding, making it convenient for users to remove the injection molded part. At the same time, the positioning groove facilitates the matching connection between the through-hole molding part and the ejector pins. In addition, the setting of the limiting groove and the protrusion helps to improve the displacement stability of the molding slider on the lower mold, making it highly practical.

[0044] An electronic cigarette casing molding die includes an upper mold 10, a lower mold 20, and a molding slider mechanism 30; wherein:

[0045] The forming slider mechanism 30 includes forming sliders 31, inclined guide posts 32, and elastic reset members (not shown in the figure). The lower mold 20 has a core 21. Four forming sliders 31 are provided, and all four forming sliders 31 are movably mounted on the lower mold 20 and arranged around the four sides of the core 21. Three adjacent forming sliders 31 have a first forming surface 311 on the side closest to the core 21. The core 21 has a second forming surface 211. The upper end of the second forming surface 211 has a mouthpiece forming part 212 for forming a mouthpiece. Another forming slider 31 has an extension part 312 extending toward the core. The extension part 312 is located near the core. A third forming surface 313 is provided on one side. The core 21 is provided with a first groove 213 corresponding to the extension. The first groove 213 passes through the second forming surface 211. The extension 312 passes through the first groove 213. The third forming surface 313 extends out of the first groove 212 and is flush with the second forming surface 211. The inclined guide post 32 is used to drive the forming slider 31 to move. The upper mold 10 has a cavity 11. The cavity 11 is provided with a fourth forming surface 111. The inclined guide post 32 is provided on the upper mold 10 and is arranged around the four sides of the cavity 11 corresponding to the four forming sliders 31. Each of the four forming sliders 31 is provided with a displacement cavity 316 for contacting the inclined guide post.

[0046] The two ends of the elastic reset member act on the molding slider 31 and the lower mold 20 respectively; when the upper mold 10 and the lower mold 20 are closed, the inclined guide post 32 moves down and extends into the displacement cavity 316 and moves toward the core in conjunction with the molding slider 31. The cavity 11 cooperates with the core 21, and the first molding surface 311, the second molding surface 211, the third molding surface 313 and the fourth molding surface 111 form an injection mold cavity 101.

[0047] Specifically, the fourth forming surface 111 is provided with a mouthpiece forming block 112 for forming a mouthpiece opening, and the mouthpiece forming part 212 is provided with a groove 214 that matches the mouthpiece forming block. The mouthpiece forming block 112 matches the groove 214, and a mouthpiece forming cavity is formed between the outer wall of the mouthpiece forming block 112 and the inner wall of the groove 214.

[0048] It also includes a gating system 40, which is disposed inside the upper mold 10. The gating system 40 includes a gating channel 41 and a branch channel 42 connecting the gating channel 41. The upper end of the gating channel 41 penetrates the upper mold 10. The branch channel 42 connects to the mouthpiece forming block 112 of the cavity 11. The mouthpiece forming block 112 has an inlet 113 on its outer side for the injection molding material to flow into the injection mold cavity. The inlet 113 is located in the upper part of the groove 214. Preferably, the inlet 113 is located away from the first molding surface. On one side of the 311 direction; thus, through the design of each component, the upper and lower molds are used to fit together the first to fourth molding surfaces and form an injection mold cavity, realizing the one-piece injection molding of the mouthpiece and the shell, so as to facilitate the subsequent assembly operation between the shell and each component, thereby improving the production efficiency and quality stability of the product, ensuring the yield of injection molded parts. With the setting of the third molding surface, corresponding concave and convex structures can be set on the third molding surface according to the assembly structure of the inner wall of the shell, thereby meeting the molding use of different models, with good usability and wide applicability.

[0049] The lower mold 20 is also provided with an ejection mechanism 50, which includes an ejector rod 51 and a drive device 52 for driving the ejector rod to rise and fall. The ejector rod 51 is movably mounted on the lower mold 20. The upper end of the ejector rod 51 passes through the core 21 and can protrude outside the core 21. Several ejector rods 51 are provided, and the several ejector rods 51 are arranged at intervals around the periphery of the core 21. One ejector rod 51 is located at the center of the groove 214. The extension 312 is provided with a vertically penetrating clearance groove 314. The clearance groove 314 extends along the length direction of the extension 312. The ejector rod 51 passes through the clearance groove 314 of the extension 312 and protrudes from the core.

[0050] Specifically, the lower end of the mouthpiece forming block 112 is provided with a through hole forming part 114, and the upper end of the push rod 51 located in the groove 214 is provided with a positioning groove 511 that matches the through hole forming part. The through hole forming part 114 is adapted to the positioning groove 511. The lower end of the mouthpiece forming block 112 contacts the upper end of the push rod 51 located in the groove 214. Preferably, the through hole forming part 114 is arranged in a gradually decreasing shape from top to bottom, and correspondingly, the positioning groove 511 is arranged in a gradually decreasing shape from top to bottom. In this way, the ejection mechanism is designed with the positions of five push rods to facilitate the ejection of the injection molded part from the lower mold after molding, thereby making it convenient for the user to remove the injection molded part. At the same time, the positioning groove is provided to facilitate the matching connection between the through hole forming part and the push rod.

[0051] Furthermore, the upper end of the lower mold 20 is provided with a second slide groove 22 corresponding to the forming slider. The four forming sliders 31 are respectively movably disposed on the corresponding second slide groove 22. Limiting grooves 221 are provided on both sides of the second slide groove 22. A protrusion 315 is provided on the forming slider 31 corresponding to the limiting groove. The protrusion 315 is restricted by the limiting groove 221. The protrusion moves on the limiting groove as the forming slider moves. In this way, the setting of the limiting groove and the protrusion helps to improve the displacement stability of the forming slider on the lower mold and has strong practicality.

[0052] The key design feature of this invention lies in its ability to integrate the mouthpiece and the housing through the design of its components. By using the mold-closing mechanism of the upper and lower molds to fit the first to fourth molding surfaces and form an injection mold cavity, it achieves one-piece injection molding of the mouthpiece and the housing. This facilitates subsequent assembly operations between the housing and other components, thereby improving production efficiency and quality stability, and ensuring a high yield rate for injection molded parts. Furthermore, the third molding surface allows for the creation of corresponding concave and convex structures based on the assembly structure of the housing's inner wall, thus meeting the molding requirements of different models. This design offers excellent usability and a wide range of applications.

[0053] Furthermore, the ejection mechanism utilizes the positional design of five ejector pins to facilitate the ejection of the injection molded part from the lower mold after molding, making it convenient for users to remove the injection molded part. At the same time, the positioning groove facilitates the matching connection between the through-hole molding part and the ejector pins. In addition, the setting of the limiting groove and the protrusion helps to improve the displacement stability of the molding slider on the lower mold, making it highly practical.

[0054] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
