[0002] The working principle of an atomizing coil is to heat the liquid aerosol matrix to its boiling point by heating the heating wire or heating mesh within the coil, thereby generating mist. Existing ceramic atomizing coils consist of a ceramic substrate and a heating mesh, with the ceramic substrate being connected to the heating mesh during the casting process. However, some existing molds for casting ceramic atomizing coils can easily cause the heating mesh to become embedded inside the ceramic substrate, thus affecting the performance of the ceramic atomizing coil. Utility Model Content

[0003] The purpose of this application is to provide a ceramic atomizing core die-casting mold to solve the technical problem in some existing related technologies where the molds for casting ceramic atomizing cores are prone to causing the heating mesh to embed inside the ceramic matrix during casting, thereby affecting the performance of the ceramic atomizing core.

[0057] Please see Figures 1-2 The ceramic atomizing core die-casting mold 10 provided in this application embodiment includes a lower mold 1, an upper mold 3 and a limiting post 2. The upper mold 3 is fastened to the lower mold 1, and the limiting post 2 is located between the upper mold 3 and the lower mold 1.

[0058] Please see Figure 3 The lower mold 1 is provided with a lower cavity 11 and a relief groove 12. Specifically, the lower cavity 11 is formed on the side of the lower mold 1 facing the upper mold 3, and the relief groove 12 is disposed on the cavity wall surface of the lower cavity 11. Please refer to... Figure 2 This illustrates the placement of the limiting post 2 in the lower cavity 11. Please refer to [link / reference]. Figure 5 When the heating mesh 20 with pins 30 connected is placed on the lower mold 1, the pins 30 are located in the clearance groove 12, and the heating mesh 20 is also placed on the lower cavity 11.

[0059] For the heating grid 20 and pins 30 placed in the lower cavity 11, please refer to Figure 5 The pins 30 are straight and parallel to the length extension direction of the heating mesh 20. The two pins 30 are connected to the outer side of the heating mesh 20 and are respectively close to the two ends of the heating mesh 20 along the bending direction.

[0060] In one example, see Figure 5 Both ends of pin 30 protrude from both ends of heating mesh 20 along the length direction; in other examples, one end of pin 30 protrudes from the end of heating mesh 20 along the length direction.

[0061] Please see Figure 6 This illustrates that the limiting post 2 passes through the heating mesh 20, and the outer peripheral side of the limiting post 2 is in contact with the inner side of the heating mesh 20. At the same time, the limiting post 2 also restricts the pin 30 from disengaging from the relief groove 12 along the radial direction of the limiting post 2.

[0062] Please see Figure 7 The diagram illustrates the upper mold 3, which has an upper cavity 31 and a die-casting hole 32. The die-casting hole 32 is connected to the upper cavity 31. When the upper mold 3 is engaged with the lower mold 1, ceramic slurry can be injected through the die-casting hole 32. It is worth noting that the die-casting hole for injecting ceramic slurry can also be located on the lower mold 1.

[0063] Please see Figure 9 , Figure 9 A cross-sectional view of a heating grid 20 with pins 30 connected inside a die-casting mold 10. The outer circumferential side of the limiting post 2 is in contact with the inner side of the heating grid 20. The lower cavity 11 and the space in the lower cavity 11 not occupied by the heating grid 20 and the limiting post 2 form the die-casting space 4 of the atomizing core ceramic substrate 40. Please refer to [link to relevant documentation]. Figure 9 This illustrates the die-casting space 4.

[0064] When casting a ceramic atomizing core using the die-casting mold 10 provided in this application embodiment, firstly, the heating mesh 20 connected with pins 30 is placed in the lower cavity 11 of the lower mold 1. Then, the limiting post 2 passes through the heating mesh 20, wherein the limiting post 2 and the heating mesh 20 are tightly fitted, so that the outer peripheral side of the limiting post 2 is in contact with the inner side of the heating mesh 20. Then, the upper mold 3 is fastened onto the lower mold 1, and an auxiliary mechanism is used to limit the position of the upper mold 3 and the lower mold 1, so that their positions remain stationary. Then, the ceramic slurry is poured through the die-casting hole 32. Please refer to Figure 10 The ceramic substrate 40 is illustrated within the die-casting space 4. Please refer to [link / reference]. Figure 11 , Figure 11 It indicates the adoption Figures 1-4 , Figure 7 The ceramic atomizing core cast by die-casting mold 10 is shown in the diagram. It is worth noting that... Figure 11 To achieve the structure of the ceramic atomizing core injection molded using die-casting mold 10, subsequent operations such as trimming and / or bending of the leads 30 of the cast ceramic atomizing core are required.

[0065] Please see Figure 12 This is a front view schematic diagram of the heating mesh 20 and the pins 30. The heating mesh 20 is bent into an arc shape by a device. The heating mesh 20 is made of metal. Because metal materials have the characteristic of springing back when bent, please refer to [the diagram]. Figure 12 The heating mesh 20 will deform and spring back at both ends along the arc direction in the direction indicated by the dotted line. The shape of the limiting post 2 matches the heating mesh 20 bent into a standard shape. If the heating mesh 20 deforms due to springback, the limiting post 2 and the heating mesh 20 will not fit completely together. This will cause ceramic slurry to flow between the heating mesh 20 and the limiting post 2 during the pouring of ceramic slurry, resulting in the heating mesh 20 being buried in the ceramic slurry. The heating mesh 20 being buried in the ceramic substrate 40 will affect the performance of the atomizing core.

[0066] In this embodiment, when the heating mesh 20 with pins 30 connected to it is placed on the lower mold 1, the two pins 30 are respectively placed in the corresponding clearance grooves 12. The position of the clearance grooves 12 on the lower mold 1 is designed such that when the two pins 30 are respectively placed in the corresponding clearance grooves 12, the heating mesh 20 can be bent into a standard shape. It can be understood that for the springback heating mesh 20, without applying an external force to bend it, the two pins 30 cannot be placed in the corresponding clearance grooves 12; only after it is bent into a standard shape can the two pins 30 be placed in the corresponding clearance grooves 12. After placing the two pins 30 into their respective clearance slots 12, insert the limiting post 2 into the heating mesh 20 and place it in the lower cavity 11. The limiting post 2 will prevent the pins 30 from moving in the radial direction of the limiting post 2. In other words, under the action of the limiting post 2, the heating mesh 20 can no longer rebound and cause the pins 30 to leave the clearance slots 12, thereby making the heating mesh 20 and the limiting post 2 completely fit together, so as to prevent the ceramic slurry from entering between the heating mesh 20 and the limiting post 2, and to prevent the heating mesh 20 from being buried in the ceramic substrate 40.

[0067] In this embodiment, by providing a relief groove 12 for placing the pin 30 on the lower mold 1, the rebound of the heating mesh 20 can be limited, so that the heating mesh 20 and the limiting post 2 are completely in contact, thereby preventing ceramic slurry from entering between the heating mesh 20 and the limiting post 2 and avoiding the heating mesh 20 from being buried in the ceramic substrate 40.

[0068] In one implementation, please refer to Figure 3 and Figure 4 The lower cavity 11 includes a lower intermediate cavity 111 and two lower side cavities 112. The two lower side cavities 112 are located on both sides of the lower intermediate cavity 111 and are connected to the lower intermediate cavity 111. Please refer to [link to relevant documentation]. Figure 7 The upper cavity 31 includes an upper intermediate cavity 311 and two upper side cavities 312. The two upper side cavities 312 are located on both sides of the upper intermediate cavity 311 and are connected to the upper intermediate cavity 311. In other embodiments, the lower cavity 11 includes a lower intermediate cavity 111 and two lower side cavities 112. There is one lower side cavity 112, one end of which is connected to the lower intermediate cavity 111, and the other end of which opens to the corresponding end of the lower mold 1. The upper cavity 31 includes an upper intermediate cavity 311 and two upper side cavities 312. There is one upper side cavity 312, one end of which is connected to the upper intermediate cavity 311, and the other end of which opens to the corresponding end of the upper mold 3. The following description mainly uses the example of the lower cavity 11 including the lower intermediate cavity 111 and two lower side cavities 112, and the upper cavity 31 including the upper intermediate cavity 311 and two upper side cavities 312.

[0069] For ease of description, the two lower cavities 112 are referred to as the first lower cavity and the second lower cavity, respectively, and the two upper cavities 312 are referred to as the first upper cavity and the second upper cavity, respectively. When the upper mold 3 is fastened onto the lower mold 1, the first upper cavity is located above the first lower cavity, and the second upper cavity is located above the second lower cavity. The shapes formed by the first upper cavity and the first lower cavity, as well as the shapes formed by the second upper cavity and the second lower cavity, all match the shape of the limiting post 2. The cavity wall surfaces of the first upper cavity, the first lower cavity, the second upper cavity, and the second lower cavity are in contact with the limiting post 2.

[0070] In one example, the first upper cavity opens to the end of the upper mold 3 on the side away from the upper intermediate cavity 311, and the first lower cavity opens to the end of the lower mold 1 on the side away from the lower intermediate cavity 111; or, the two ends of the second upper cavity open to the end of the upper mold 3 on the side away from the upper intermediate cavity 311, and the two ends of the second lower cavity open to the end of the lower mold 1 on the side away from the lower intermediate cavity 111; or, the first upper cavity opens to the end of the upper mold 3 on the side away from the upper intermediate cavity 311, the first lower cavity opens to the end of the lower mold 1 on the side away from the lower intermediate cavity 111, and the two ends of the second upper cavity open to the end of the upper mold 3 on the side away from the upper intermediate cavity 311, and the two ends of the second lower cavity open to the end of the lower mold 1 on the side away from the lower intermediate cavity 111.

[0071] In one example, see Figure 1 The limiting post 2 includes a main body 21 and a limiting post end 22. The limiting post end 22 is disposed at one end of the main body 21 and connected to it. The diameter of the limiting post end 22 is larger than the diameter of the main body 21, and the limiting post end 22 is located outside the lower mold 1 and the upper mold 3. When the limiting post 2 is placed on the lower mold 1 where the heating mesh 20 is placed, the end of the main body 21 away from the limiting post end 22 is inserted into the lower cavity 112 from one end of the lower mold 1. In this example, by setting the diameter of the limiting post end 22 to be larger than the diameter of the main body 21, it is easier for the user to insert the limiting post end 22 into the lower mold 1 by hand.

[0072] In this example, by setting the lower cavity 11 to include a lower intermediate cavity 111 and two lower side cavities 112, and the upper cavity 31 to include an upper intermediate cavity 311 and two upper side cavities 312, the limiting post 2 is stably supported on the lower mold 1, which facilitates the fitting of the limiting post 2 with the inner surface of the heating mesh 20.

[0073] In one example, clearance grooves 12 are provided on the cavity walls of both lower cavities 112, and one end of any clearance groove 12 is connected to the lower intermediate cavity 111. In this example, it is suitable for the case where both ends of the pin 30 protrude from both ends of the heating mesh 20 along the length direction, and the two ends of the pin 30 are respectively supported on the two lower cavities 112, so as to better and more stably limit the heating mesh 20 on the lower mold 1.

[0074] Please see Figure 3 and Figure 4 The diagram illustrates the lower intermediate cavity 111. Please refer to [link / reference]. Figure 5 The diagram shows the upper intermediate cavity 311. When the upper mold 3 is fastened to the lower mold 1, the upper intermediate cavity 311 is located above the lower intermediate cavity 111. The space enclosed by the upper intermediate cavity 311 and the intermediate cavity, apart from the space occupied by the heating grid 20 and the limiting post 2, is the die casting space 4.

[0075] Please see Figures 3-4 as well as Figure 7 The diagram illustrates a lower intermediate cavity 111 and an upper intermediate cavity 311 of a certain shape. Please refer to [link / reference]. Figure 15 and Figure 18 The diagram illustrates a lower intermediate cavity 111 and an upper intermediate cavity 311 of another shape. By setting different shapes of lower intermediate cavities 111 and upper intermediate cavities 311, ceramic substrates 40 of different shapes can be cast.

[0076] The following mainly introduces two different die-casting molds 10 that form the die-casting space 4.

[0077] Example 1:

[0078] In one implementation, please refer to Figure 3 and Figure 4 The lower intermediate cavity 111 includes a first groove 1111 and a second groove 1112. The second groove 1112 is opened in the middle region of the bottom surface of the first groove 1111. The two ends of the second groove 1112 are respectively connected to the two lower cavities 112. The limiting post 2 fits into the second groove 1112.

[0079] In this embodiment, since the second groove 1112 is located in the middle region of the bottom surface of the first groove 1111, and the depth of the second groove 1112 is greater than the depth of the first groove 1111, the limiting post 2 fits into the second groove 1112, and the two ends of the heating mesh 20 along the bending direction are supported on the bottom surface of the first groove 1111. Please refer to [link to relevant documentation]. Figure 9 The die-casting space 4 does not completely surround the limiting column 2 in the circumferential direction, so the injection-molded ceramic matrix 40 does not form a cylindrical shape.

[0080] In one example, see Figure 10The upper middle cavity 311 has a square cross-section, which allows the injection-molded ceramic substrate 40 to be molded as... Figure 11 The block shape is shown in the illustration; in other examples, the cross-section of the upper central cavity 311 is arc-shaped.

[0081] In this embodiment of the application, by opening the second groove 1112 in the middle region of the bottom surface of the first groove 1111 and fitting the limiting post 2 to the second groove 1112, a non-cylindrical ceramic substrate 40 can be injection molded to facilitate the preparation of an atomizing core of the desired shape.

[0082] In one implementation, please refer to Figure 4 The bottom surface of the first groove 1111 includes a first groove bottom surface region 1113 and a second groove bottom surface region 1114.

[0083] In one example, the first groove bottom area 1113 and the second groove bottom area 1114 are planar; in other examples, the first groove bottom area 1113 and the second groove bottom area 1114 are inclined, for example, the first groove bottom area 1113 is inclined from the end near the second groove 1112 to the end away from the second groove 1112.

[0084] In one example, see Figure 3 and Figure 4 Along the axial direction of the limiting post 2, the ends of the first groove bottom surface region 1113 and the second groove bottom surface region 1114 protrude upward to form a protrusion 1115. A clearance groove 12 is provided on the side of the protrusion 1115 near the second groove 1112. By providing the protrusion 1115 on the first groove bottom surface region 1113 and the second groove bottom surface region 1114, please refer to... Figure 11 This allows the pins 30 at the positions corresponding to the protrusions 1115 to be exposed outside the ceramic substrate 40.

[0085] In one example, both lower cavities 112 have clearance grooves 12 on their cavity walls, and one end of any clearance groove 12 is connected to the lower middle cavity 111.

[0086] In this embodiment of the application, by providing protrusions 1115 on the bottom surface region 1113 of the first groove and the bottom surface region 1114 of the second groove, an atomizing core of the required shape can be injection molded.

[0087] In one implementation, please refer to Figure 3 and Figure 4 Both the bottom surface region 1113 of the first groove and the bottom surface region 1114 of the second groove near the second groove 1112 have a support surface 1116. The two ends of the support surface 1116 along the length direction are respectively connected to the protrusion 1115 and the side of the first groove 1111. The support surface 1116 is used to support one end of the heating grid 20 along the bending direction.

[0088] In this embodiment of the application, by providing support curved surfaces 1116 in the first bottom surface region 1113 and the second bottom surface region 1114 of the groove, the two ends of the heating mesh 20 along the bending direction can be better supported.

[0089] In one implementation, the bottom surface of the upper intermediate cavity 311 is a plane; or, the bottom surface of the upper intermediate cavity 311 is an arc surface; or, a protruding structure 33 is provided on the bottom surface of the upper intermediate cavity 311. Please refer to [link / reference]. Figure 7 The diagram illustrates the raised structure 33 on the bottom surface of the upper intermediate cavity 311, so that a groove is formed on the side of the ceramic substrate 40 away from the heating grid 20.

[0090] When will Figure 11 When the atomizing core shown is applied to an atomizer, the aerosol matrix within the atomizer can seep into and flow towards the heating grid 20 through the side of the ceramic substrate 40 away from the heating grid 20. When current flows through the heating grid 20, it heats the aerosol matrix, causing it to evaporate. When a groove is formed on the side of the ceramic substrate 40 away from the heating grid 20, the distance between this side and the heating grid 20 can be reduced, which helps to reduce the travel distance of the aerosol matrix within the ceramic substrate 40, thereby improving the wicking speed of the ceramic substrate 40. When the bottom surface of the upper intermediate cavity 311 is an arc surface, the side of the ceramic substrate 40 facing away from the heating grid 20 is an arc surface, which is the same as the side of the ceramic substrate 40 facing away from the heating grid 20 being a flat surface. The arc surface can increase the area of ​​the side of the ceramic substrate 40 facing away from the heating grid 20. The larger the area of ​​the side of the ceramic substrate 40 facing away from the heating grid 20, the greater the contact area with the aerosol matrix, which in turn helps to improve the oil guiding speed of the ceramic substrate 40 and improve the atomization efficiency of the atomizing device.

[0091] Example 2:

[0092] In one implementation, please refer to Figure 15 and Figure 16 The diameter of the lower intermediate cavity 111 is larger than the diameter of the lower side cavity 112. Please refer to [link / reference]. Figure 18 The diameter of the upper middle cavity 311 is larger than the diameter of the upper side cavity 312.

[0093] like Figure 15 As shown, when the limiting post 2 is supported on the lower cavity 11, the circumferential side of the limiting post 2 contacts the two lower cavities 112, while the lower middle cavity 111 does not contact the limiting post 2; when the upper mold 3 is fastened onto the lower mold 1, the two upper cavities 312 contact the limiting post 2, while the upper middle cavity 311 does not contact the limiting post 2. In other words, as... Figure 20As shown, the die-casting space 4 surrounds the limiting post 2 in the circumferential direction, causing the injection-molded ceramic substrate 40 to form a cylindrical shape. Please refer to [link / reference]. Figure 21 This indicates the adoption of, for example Figures 13-14 , Figure 18 The atomizing core is cast by die-casting mold 10 as shown, and the ceramic substrate 40 surrounds the heating mesh 20 in a cylindrical shape.

[0094] In one example, see Figure 15 and Figure 16 The lower middle cavity 111 has a circular arc surface; please refer to [link / reference]. Figure 18 The upper intermediate cavity 311 has an arc surface, which causes the lower intermediate cavity 111 and the upper intermediate cavity 311 to form a cylindrical shape, thus allowing for injection molding of materials such as... Figure 21 The cylindrical ceramic substrate 40 is shown in the illustration; in other examples, the lower intermediate cavity 111 and the upper intermediate cavity 311 can also be enclosed in a square shape, thereby allowing the injection molding of a cuboid ceramic substrate 40.

[0095] In this example, both lower cavities 112 have clearance grooves 12 on their cavity walls, and one end of each clearance groove 12 is connected to the lower intermediate cavity 111. Please refer to [link / reference]. Figure 17 When the heating mesh 20 with pins 30 is placed on the lower cavity 11, the heating mesh 20 does not contact the lower middle cavity 111. The heating mesh 20 is inserted into the clearance grooves 12 of the two lower cavities 112 through the two ends of the pins 30, so that the heating mesh 20 is supported on the lower mold 1.

[0096] In this example, please see Figure 17 The heating mesh 20 connected with pins 30 has the following shape: the heating mesh 20 is bent into an arc shape and the two ends of the heating mesh 20 along the bending direction are close to each other. The two pins 30 are close to the two ends of the heating mesh 20 along the bending direction. The two pins 30 are straight and parallel to the axis of the heating mesh 20. The two pins 30 are connected to the outer side of the heating mesh 20 and the two pins 30 are in contact.

[0097] In this embodiment of the application, by setting the diameter of the lower intermediate cavity 111 to be larger than the diameter of the lower side cavity 112 and the diameter of the upper intermediate cavity 311 to be larger than the diameter of the upper side cavity 312, a cylindrical ceramic substrate 40 can be cast.

[0098] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
