DETAILED DESCRIPTION

[0030] ​The application will be described in further detail below with specific reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, it will be apparent to one skilled in the art that the application can be practiced without these specific details. In other instances, well-known structures have not been described in detail in order to avoid obscuring the application. In the following description, the terms "couple," "coupled," "connection," and "connected" are used to describe both an indirect and a direct electrical connection (coupling) between two elements.

[0031] In addition, features, operations, or steps described in the specification can be combined in any suitable manner without departing from the scope of the application. Similarly, steps in the methods described do not have to be performed in the precise order described, unless otherwise specified. Thus, the steps of the methods described can be performed in any order that is appropriate, unless otherwise specified.

[0032] The serial numbers of components in the text, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in the application include direct and indirect connections (couplings) unless otherwise specified.

[0033] In view of the low installation efficiency of the existing product spring sheet, in the application, the spring sheet is placed in the injection mold cavity to realize injection molding of the spring sheet, directly omitting the original hardware spring sheet installation process, thereby avoiding the defects of low installation efficiency of the existing technology spring sheet and only manual installation, and having higher spring sheet installation efficiency and the like.

[0034] Figures 1 to 11 An atomizing device in an embodiment of the application is shown, which comprises an atomizing device module. The atomizing device module is produced by an injection molding mold which can be used to complete the assembly of the hardware spring sheet in the mold injection, which can include a lower mold assembly 200, an upper mold assembly 100, and a front mold assembly 300; the lower mold assembly 200 includes a lower forming cavity 220; the upper mold assembly 100 includes an upper forming cavity 120; the front mold assembly 300 is arranged on one side of the lower mold assembly 200, and is slidably inserted between the upper mold assembly 100 and the lower mold assembly 200, and the front mold assembly includes a front mold cavity for abutting the spring sheet assembly 600, and the front mold cavity, the lower forming cavity 220, and the upper forming cavity 120 form an injection molding cavity.

[0035] The lower mold assembly 200 includes an insert 210 disposed below the front mold cavity 310. The upper part of the insert 210 is provided with a limiting part 212, which is disposed near the lower molding cavity 220. The limiting part 212 extends from the insert 210 in a direction away from the insert 210. The shape of the limiting part 212 matches the shape of the spring assembly 600, and the limiting part 212 limits the spring assembly 600.

[0036] The lower molding cavity 220 and the upper molding cavity 120 form a complete injection molding cavity. The spring sheet 620 assembly 600 is placed in the injection molding cavity. The spring sheet 620 assembly 600 is limited by the insert 210. The spring sheet 620 assembly 600 is directly injection molded in the mold, which directly eliminates the original installation process of the metal spring sheet 620 and merges it into the injection molding process, thereby improving the production yield.

[0037] In some embodiments, the upper mold assembly 100 is further provided with a gating assembly 110, which is disposed in the upper mold assembly 100 and extends through the upper mold assembly 100. The gating assembly 110 is provided with a gating channel 111, which extends through the upper mold assembly 100 and connects the injection cavity and the external space.

[0038] In some embodiments, there are two gating channels 111.

[0039] In some embodiments, the casting assembly 110 is provided with a protruding snap-fit ​​portion, and the top of the upper mold assembly 100 is provided with a limiting groove at the casting assembly 110. The snap-fit ​​portion and the limiting groove cooperate with each other to limit the casting assembly 110 so that the casting assembly 110 will not sink.

[0040] In some embodiments, the front mold assembly 300 abuts against the spring sheet onto the insert, and the front mold assembly 300 presses the spring sheet firmly onto the insert.

[0041] In some embodiments, the front mold assembly 300 has a protrusion 320 on the side near the injection cavity. The protrusion 320 extends from the front mold assembly toward the injection cavity. The protrusion can form a deep groove 710 in the injection molded part 700 for magnet mounting.

[0042] In some embodiments, the front mold assembly 300 is provided with a through groove 330 at one end away from the lower mold assembly. The through groove 330 is mainly used to connect with moving parts so that the front mold assembly 300 can slide back and forth.

[0043] Figures 2 to 5In one embodiment, the lower mold assembly 200 may include a slanted ejector unit 400 passing through the lower mold assembly 200. The slanted ejector unit 400 is disposed below the lower molding cavity 220. When the upper mold assembly 100 and the lower mold assembly 200 are closed, the slanted ejector unit 400 is built into the bottom surface of the lower molding cavity 220. When the upper mold assembly 100 and the lower mold assembly 200 are separated, the slanted ejector unit 400 protrudes from the bottom surface of the lower molding cavity 220. The slanted ejector can automatically eject the injection molded product in the injection cavity for material discharge, thereby improving the degree of automation of the mold.

[0044] Figure 1 and Figure 2 The inclined ejector unit 400 is shown to include an ejector pin in one embodiment. The lower mold assembly 200 includes an inclined hole 410 passing through the lower mold assembly 200. The direction of the inclined hole 410 forms an angle with the direction of the mold closing movement of the upper mold assembly 100 and the lower mold assembly 200. The insertion section of the ejector pin matches the shape of the inclined hole 410. The end of the insertion section of the ejector pin is located in the injection cavity. The inclination direction of the injection mold inclined ejector should be consistent with the mold opening and closing direction. This can continuously strengthen the force and angle of mold opening and closing, making the mold release more continuous and easier. In addition, the design of the inclined ejector can reduce the friction between the mold and the injection molded product, avoid the product being stretched or deformed during the demolding process, and improve the quality of the injection molded product and production efficiency.

[0045] Figure 1 and Figure 2 The ejector pin and the oblique hole are shown in one embodiment. The ejector pin and the oblique hole may be mirrored with respect to the lower molding cavity 220 to increase the ejection force of the injection molded part, so that the injection molded part can be smoothly ejected from the mold.

[0046] Figure 8 In one embodiment, the limiting part 212 may include a plurality of positioning grooves 213 on the side of the limiting part 212 away from the lower molding cavity 220. The shape and position of the plurality of positioning grooves 213 match the spring assembly 600, and the positioning grooves 213 enhance the positioning accuracy of the spring assembly 600.

[0047] Figure 8 The insert 210, as shown in one embodiment, may include a clearance groove 214 on its top. The clearance groove 214 extends from the center of the limiting portion 212 and is hollowed out in a direction away from the lower mold assembly 200. The two sides of the clearance groove 214 protrude from the lower mold assembly 200 and abut against the spring piece 620. This reduces the contact between the spring piece 620 and the mold. In plastic molds, clearance should be used between two components unless they need to be tightly fitted. This reduces the chance of interference between components and also reduces the difficulty of mold fitting by fitters.

[0048] Figure 8The insert 210 is shown in one embodiment to include a positioning member 230 extending from the insert 210 toward the upper mold assembly 100, the positioning member 230 passing through the spring and limiting the spring.

[0049] In some embodiments, the spring strip is provided with a positioning hole, and the positioning member 230 passes through the positioning hole to limit the material strip, so that the spring strip is positioned relatively accurately, and at the same time, the spring strip will not be offset due to pressure when the mold is closed.

[0050] Figure 2 and Figure 8 The positioning member 230 is shown in one embodiment as a rod, which is movably disposed in the lower mold assembly 200 and the insert 210.

[0051] Figure 3 and Figure 8 The front mold assembly 300 and the limiting part 212 are shown. In one embodiment, the front mold assembly 300 may abut against the spring sheet 620 onto the limiting part 212, and the limiting part 212 and the front mold assembly 300 clamp the spring sheet 620 assembly 600.

[0052] Figures 1 to 5 Atomizing device module is also provided, the atomizing device module including spring sheet assembly 600, the atomizing device module being produced by the above-mentioned injection molding mold.

[0053] Figure 8 The spring assembly 600 shown in one embodiment may include a plurality of springs 620 and a connecting plate 610. The plurality of springs 620 are grouped and disposed on the connecting plate 610, and at least one group of springs 620 is disposed at the injection cavity position. Each spring 620 bends upward from one side of the connecting plate 610, extends upward to a specified distance, and then folds downward away from the connecting plate to form a groove 621.

[0054] Figure 8 The spring 620 is shown in one embodiment and may include an implant segment 625 inserted into the injection molded part, a vertical segment 623 connected to a connecting plate, and a transition segment 624 connecting the implant segment 625 and the vertical segment 623.

[0055] Figure 10 and Figure 11The spring assembly 600, as shown in one embodiment, may include a fracture groove 622 at the connection between the spring 620 and the connecting plate. The component of the fracture groove 622 near the connecting plate belongs to the connecting plate, and the component of the other side belongs to the spring 620. The portion of the spring 620 near the fracture groove 622 is a vertical section 623, which is flush with the plane of the injection cavity near the front mold assembly 300. The fracture groove 622 is mainly used to reduce the bonding force between the spring 620 and the connecting plate, making it easier to break at a fixed position, reducing the force required for breaking, and improving the breaking efficiency. After breaking, several springs 620 are directly fixed in the injection molded part, while the connecting plate is removed.

[0056] Understandably, the vertical section is flush with one side of the injection cavity, which makes it easy to press the vertical section firmly and then break the connecting plate. This prevents the vertical section from being unable to be pressed firmly due to the injection cavity plane being higher than the vertical section, thus avoiding the situation where the vertical section is deformed due to external force when it is broken.

[0057] Understandably, because the clamping pressure between the molds is relatively high, the spring sheet will cause damage and wear to the corresponding position of the lower mold, so it is necessary to set the insert 210 at the corresponding position for easy replacement.

[0058] This application also provides an atomizing device, which includes an atomizing device module produced by the above-mentioned injection molding die. The atomizing device is a device for atomizing atomizing matrix into an aerosol.

[0059] It is understood that the above embodiments only illustrate preferred embodiments of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this application. It should be noted that, for those skilled in the art, without departing from the concept of this application, the above technical features can be freely combined, and several modifications and improvements can be made, all of which fall within the protection scope of this application. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of this application should fall within the scope of the claims of this application.
