[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present application, the specific implementation methods of the present application are now described in detail with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the housing 2 of the current electronic atomization device includes a buckle position 20 which is arranged on the inner side thereof in a convex shape. The design of the buckle position 20 can facilitate the assembly of the electronic atomization device and realize a screwless installation method.

[0029] like Figure 2As shown, the mold structure of the present application is used to produce the shell of an electronic atomization device, so that a plurality of buckle positions 20 are formed on the inner surface of the shell 2. The mold structure includes an upper mold 42, a lower mold 1 and an ejector plate 41. The upper mold and the lower mold are also referred to as the front mold and the rear mold, respectively. The ejector plate 41 is sleeved on the outer periphery of the lower mold 1. The upper mold 42 and the lower mold 1 are covered to form a mold cavity for injection molding. A glue injection port (not shown) is provided on the upper mold 42 or the lower mold 1. When the shell 2 is made, glue is injected into the mold cavity through the glue injection port. After the shell 2 is formed, the ejector plate 41 sleeved on the outer periphery of the lower mold 1 is located below the shell 2. The ejector plate 41 applies an upward force on the four sides of the shell 2 to eject the shell 2.

[0030] Figure 3 The state when the housing 2 is sleeved on the lower mold 1 is shown. Figure 2 The state when the shell 2 is separated from the lower mold 1 is shown. After the shell 2 is formed, the shell 2 and the lower mold 1 are tightly fitted together through the buckle position 20. Therefore, how to smoothly remove the shell 2 from the lower mold 1 is a key factor affecting the yield rate of the shell 2. As described in the background technology, the traditional practice is to adopt a slanted top mold structure. Such a defect is low production efficiency, and in the process of disassembling the shell 2, it will cause adverse secondary effects on the appearance of the shell 2, affecting the product yield rate of the shell 2. The present application aims to improve the mold structure and construct a new mold structure so that the shell 2 can be smoothly removed from the mold structure after the buckle position is formed, and the disassembly process does not have a secondary effect on the appearance of the shell 2.

[0031] like Figure 4 As shown, in some embodiments, the mold structure includes a mold core 10, a first movable part 11, and a second movable part 12. The ejector plate 41 is sleeved on the outer periphery of the mold core 10, and the ejector plate 41 is movably arranged along the length direction of the mold core 10, and is used to move toward the shell 2 after the shell 2 is formed, and to apply force to the four sides of the shell 2 to eject the shell 2 to achieve demolding. The mold core 10 is in direct contact with the shell 2 of the electronic atomization device, and provides an installation foundation for the shell 2 of the electronic atomization device to form the buckle position 20. The first movable part 11 and the second movable part 12 are both movable, and the first movable part 11 and the buckle position 20 on the shell 2 of the electronic atomization device are corresponding in shape and size, and the buckle position 20 structure finally formed on the shell 2 of the electronic atomization device corresponds to the structure of the first movable part 11. The second movable part 12 is used to drive the first movable part 11 to move to different positions before and after the buckle position 20 is formed.

[0032] like Figures 4 to 6As shown, the mold core 10 has a molding surface 3 on which the shell 2 of the electronic atomization device is molded, and the molding surface 3 includes a top surface 31 and a side surface 32 that are vertically connected. The side surface 32 is provided with a through hole 40, and the through hole 40 connects the inside and the outside of the mold core 10. The top surface 31 and the side surface 32 of the mold core 10 correspond to the top surface and the side surface of the shell 2, respectively. After the shell 2 is molded, the top surface of the shell 2 is in contact with the top surface 31 of the mold core 10, and the side surface of the shell 2 is in contact with the side surface 32 of the mold core 10.

[0033] The mold core 10 has a slide groove 103 opened inside and a through hole 40 that passes through the side surface 32 and is connected to the slide groove 103. The slide groove 103 passes through the bottom of the mold core 10 and extends toward the top surface 31. The second movable member 12 is slidably arranged in the slide groove 103, and the first movable member 11 is arranged in the through hole 40 and connected to the second movable member 12. The first movable member 11 can move in the through hole 40 during the sliding process of the second movable member 12 along the slide groove 103, so as to extend into the mold cavity before the shell 2 is formed, and extend from the mold cavity after the shell 2 is formed and accommodated in the through hole 40. That is, when the second movable member 12 moves as an active member, it can drive the first movable member 11 to move in a direction perpendicular to the side surface 32. The direction perpendicular to the side surface 32 is also the length extension direction of the through hole 40. Therefore, the first movable member 11 can be just fitted in the through hole 40, and the first movable member 11 can also partially extend through the through hole 40 to the outside of the slide groove 103, and can also retract into the slide groove 103 along the length extension direction of the through hole 40. In this way, when the housing 2 is produced, the first movable member 11 can be driven by the second movable member 12 to move at the through hole 40 along the direction close to the outside of the slide groove 103 into the mold cavity.

[0034] like Fig. 9 In the illustrated embodiment, a recessed portion 110 is provided at the free end of the first movable member 11, specifically, on the surface of the first movable member 11 facing the outside of the slide groove 103, and the recessed portion 110 has a preset shape of the intended buckle position 20. For example, if the cross section of the buckle position 20 is wedge-shaped or trapezoidal, the cross section of the recessed portion 110 on the surface of the first movable member 11 is a corresponding wedge-shaped or trapezoidal. The first movable member 11 can form a buckle position 20 of a preset shape on the inner surface of the shell 2 in the mold cavity. After the buckle position 20 of the shell 2 is formed, the first movable member 11 is driven by the second movable member 12 to move a distance in the direction close to the slide groove 103 at the through hole 40, so that the first movable member 11 retracts and separates from the buckle position 20 on the shell 2, so that the shell 2 can be easily removed from the mold core 10, and in the process of removing the shell 2, because the shell 2 does not contact the first movable member 11, the appearance of the shell 2 will not be affected secondary.

[0035] In some embodiments, the lower mold 1 includes a plurality of first movable members 11 and a plurality of second movable members 12. Figure 6 and Figure 7As shown, a plurality of slide grooves 103 are provided on the inner side of the mold core 10. The number of the slide grooves 103 is consistent with the number of the second movable parts 12. A second movable part 12 is provided in each slide groove 103. The slide groove 103 is connected to the through hole 40, and the second movable part 12 is slidably engaged in the slide groove 103. At least one first movable part 11 is connected to each second movable part 12. The first movable part 11 and the second movable part 12 can be connected one-to-one (that is, one second movable part 12 is connected to and drives one first movable part 11), or can be connected one-to-many (for example, one second movable part 12 is connected to and drives two or more first movable parts 11). The slide groove 103 mainly provides guidance for the movement of the second movable part 12, so the number of the slide grooves 103 is consistent with the number of the second movable parts 12, and one slide groove 103 is corresponding to and slides with one second movable part 12. The length extension direction of each slide groove 103 can be consistent, so as to ensure that the movement direction of each second movable part 12 is consistent. Specifically, the free end of the second movable member 12 extends out of the slide groove 103 of the mold core 10 so as to be driven to slide in the mold core 10 .

[0036] like Figures 5 to 8 As shown, in some embodiments, the plurality of second movable members 12 include a first sub-movable member 12a and a second sub-movable member 12b. The first sub-movable member 12a of the plurality of second movable members 12 is connected to the two first movable members 11 on both sides along its width direction. Correspondingly, the first sub-movable member 12a and the two first movable members 11 can be used to make a first housing 2, and the first housing 2 has a plurality of buckle positions 20, and at least two buckle positions 20 are symmetrically arranged on the inner wall surfaces on both sides opposite to each other.

[0037] The second sub-movable member 12b among the plurality of second movable members 12 is arranged at one end of the mold core 10, and the second sub-movable member 12b is connected to two first movable members 11 on both sides along the width direction thereof, and is connected to one first movable member 11 on the side facing away from the first sub-movable member 12a along the thickness direction thereof. Thus, the second sub-movable member 12b is connected to three first movable members 11 at the same time. The second sub-movable member 12b and the three first movable members 11 can be used to manufacture the second type of housing 2, and the second type of housing 2 has at least three buckle positions 20, and buckle positions 20 are respectively provided on the three adjacent inner wall surfaces of the second type of housing 2.

[0038] like Figures 5 to 8 As shown, in some embodiments, the lower mold 1 includes at least one first sub-movable member 12a and two second sub-movable members 12b, the two second sub-movable members 12b are respectively arranged at opposite ends of the mold core 10 along the thickness direction of the second movable member 12, and the first sub-movable member 12a is arranged between the two second sub-movable members 12b. Figure 8In the illustrated embodiment, three second movable parts 12 are arranged in parallel and spaced apart, the second movable part 12b on the left is connected to three first movable parts 11, the first movable part 12a in the middle is connected to two first movable parts 11, and the second movable part 12b on the right is connected to three first movable parts 11. Thus, the eight first movable parts 11 are driven by the three second movable parts 12, and only three parallel and spaced slide grooves 103 need to be provided on the core 10, which retains most of the physical structure of the core 10 and makes the core 10 have better rigidity. Thus, one first movable part 12a and two second movable parts 12b are connected to eight first movable parts 11 in total. One first movable part 12a, two second movable parts 12b and eight first movable parts 11 can be used to make a third type of housing 2, and buckles 20 are provided on the four inner wall surfaces connected to each other on the third type of housing 2.

[0039] It can be understood that in other embodiments, there can be multiple first sub-active parts 12a, all of which are located between two second sub-active parts 12b, and the first sub-active parts 12a and the first sub-active parts 12a, the second sub-active parts 12b and the second sub-active parts 12b, and the first sub-active parts 12a and the second sub-active parts 12b are all arranged in parallel.

[0040] In one embodiment, a plurality of recessed portions 110 are formed at the free end of at least one first movable member 11, and each recessed portion 110 corresponds to a buckle position 20. Figure 7 As shown, the side surface 32 includes two long side surfaces 321 and two short side surfaces 322, and the long side surfaces 321 and the short side surfaces 322 together form a rectangular outline, and the first movable member 11 penetrating the short side surfaces 322 has two recessed portions 110 that match the outer shape of the buckle positions 20 of the housing 2, and the two buckle positions 20 corresponding to the short side surfaces 322 are formed by the same first movable member 11. Correspondingly, the housing 2 produced by the mold also has two long side inner wall surfaces and two short side inner wall surfaces, which are adapted to the shape of the mold core 10. That is, the two long side surfaces 321 are arranged in parallel and spaced apart, and the two short side surfaces 322 are arranged in parallel and spaced apart, and the two sides of each short side surface 322 are respectively connected to the two long side surfaces 321, and the two sides of each long side surface 321 are respectively connected to the two short side surfaces 322, thereby the two long side surfaces 321 and the two short side surfaces 322 together form a closed rectangular outline. The two long side surfaces 321 are each provided with three through holes 40, and the two short side surfaces 322 are each provided with one through hole 40, and the eight through holes 40 are respectively provided in one-to-one correspondence with the eight first movable members 11. Each first movable member 11 can move back and forth at the corresponding through hole 40 in a direction perpendicular to the side surface 32.

[0041] The above embodiment is described by taking the example that the inner wall surface of the long side of the shell 2 is provided with three pairs of buckle positions 20 and the inner wall surface of the short side is provided with two pairs of buckle positions 20, and the corresponding mold core 10 has three through holes 40 for corresponding to the three pairs of buckle positions 20 on the inner wall surface of the long side of the shell 2, and the short side surface 322 is provided with a through hole 40 corresponding to the buckle position 20. It can be understood that the number of buckle positions 20 on the inner wall surface of the long side and the inner wall surface of the short side of the shell 2 can be adjusted as needed, and the number of corresponding through holes 40, the first sub-active member 12a, the second sub-active member 12b, and the first active member 11 on the mold core 10 can be adjusted accordingly.

[0042] Furthermore, if Figure 7 As shown, in some embodiments, the area of ​​the through hole 40 on the long side surface 321 may be smaller than the area of ​​the through hole 40 on the short side surface 322. Correspondingly, the volume of the first movable part 11 at the through hole 40 on the long side surface 321 is larger than the volume of the first movable part 11 at the through hole 40 on the short side surface 322. Each first movable part 11 may have a preset shape for forming a buckle position 20. Three buckle positions 20 may be formed on each long side inner wall surface of the shell 2 formed in this way, and one buckle position 20 may be formed on each short side inner wall surface. And the buckle position area on the long side inner wall surface of the shell 2 may be larger than the buckle position area on the short side inner wall surface. As shown in FIG. Figure 1 As shown, in other embodiments, the shapes and sizes of the buckle positions 20 on the housing 2 may be equal. A single first movable member 11 may also have two or more preset shapes for forming the buckle positions 20. For example, the first movable member 11 at the through hole 40 on the short side surface 322 may have two preset shapes for forming the buckle positions 20. Figure 1 Two buckle positions 20 may be formed on the inner wall surface of each short side of the housing 2 as shown.

[0043] like Figure 5 and Figure 6 As shown, in some embodiments, the moving direction of the second movable member 12 is perpendicular to the top surface 31. That is, the moving direction of the second movable member 12 is perpendicular to the moving direction of the first movable member 11. Specifically, in order to make the moving direction of the second movable member 12 perpendicular to the moving direction of the first movable member 11, the end of the second movable member 12 facing the first movable member 11 is provided with a slope 123, and the first movable member 11 slides with the slope 123. That is, each second movable member 12 can be provided with a slope 123 at one end facing the first movable member 11, and the first movable member 11 slides with the slope 123 on each second movable member 12, so as to achieve that the moving direction of the second movable member 12 is perpendicular to the moving direction of the first movable member 11.

[0044] Specifically, each of the second movable members 12 includes a first end close to the first movable member 11 and a second end away from the first movable member 11. The second end is used to connect with the mold frame (not shown), and the second movable member 12 is driven to move in a direction perpendicular to the top surface 31 of the mold core 10 through a guide mechanism on the mold frame. The lateral dimension (i.e., the direction perpendicular to the side surface 32 of the mold core 10) of a portion of the area on the first end gradually increases in a direction close to the second end, or in other words, the lateral dimension (i.e., the direction perpendicular to the side surface 32 of the mold core 10) of a portion of the area on the first end gradually decreases in a direction close to the end of the first end, thereby forming an inclined surface 123.

[0045] like Figure 8 As shown, in some embodiments, a first mounting portion 124 is provided on the inclined surface 123 of each second movable member 12, and a second mounting portion 112 is provided on each first movable member 11, and the first mounting portion 124 and the second mounting portion 112 are slidably engaged and connected. The first mounting portion 124 can be arranged at the position of the inclined surface 123 of the second movable member 12. Specifically, the connected first mounting portion 124 and the second mounting portion 112 can be respectively one of a protrusion and a groove, and the protrusion and the groove are slidably engaged and connected.

[0046] For example Figure 8 In the illustrated embodiment, the first sub-active member 12a located in the middle has a protruding portion protruding on both sides along the width direction thereof, that is, the first sub-active member 12a located in the middle has two protruding portions protruding on it. The second sub-active member 12b located on the left side also has a protruding portion protruding on both sides along the width direction thereof, and a groove is provided on one side along the thickness direction thereof, that is, the second sub-active member 12b located on the left side has two protruding portions protruding on it, and one groove is concavely provided. The second sub-active member 12b located on the right side also has a protruding portion protruding on both sides along the width direction thereof, and a groove is provided on one side along the thickness direction thereof, that is, the second sub-active member 12b located on the right side has two protruding portions protruding on it, and one groove is concavely provided. Thus, the three second active members 12 have a total of six protruding portions and two grooves. Among the eight first movable parts 11, six first movable parts 11 corresponding to the two long side surfaces 321 of the mold core 10 are respectively provided with a groove, and two first movable parts 11 corresponding to the two short side surfaces 322 of the mold core 10 are respectively provided with a protrusion. Thus, the eight first movable parts 11 have a total of six grooves and two protrusions. The groove on the first movable part 11 is slidably engaged with the protrusion on the second movable part 12, and the groove on the second movable part 12 is slidably engaged with the protrusion on the first movable part 11.

[0047] Furthermore, if Figure 8As shown, in some embodiments, the first mounting portion 124 and the second mounting portion 112 are fitted into each other and slidably connected by means of a dovetail groove and a dovetail tenon, the protrusion is in a dovetail shape, and the groove is a dovetail groove. Thus, a dovetail tenon is formed at the connection between the second movable member 12 and the first movable member 11, so that the corners of the second movable member 12 and the first movable member 11 are highly joined, and the forces are prevented from being disengaged from each other during the buckling molding process of the housing 2.

[0048] like Figure 7 As shown, in some embodiments, the mold core 10 includes a first part 101 and a second part 102 with different cross-sectional areas, the cross-sectional area of ​​the second part 102 is larger than the cross-sectional area of ​​the first part 101, and the molding surface 3 is arranged on the first part 101. The ejector plate 41 is sleeved on the outer periphery of the first part 101. The second part 102 has four corners, and the four corners are respectively provided with connecting holes 105. Through the cooperation of the connecting holes 105 and bolts (not shown), the mold core 10 can be locked and connected to the mold frame. Furthermore, each second movable part 12 is also provided with a connecting hole (not shown) for connecting the second movable part 12 with the guide mechanism on the mold frame.

[0049] like Figure 1 As shown, the lower end surface 25 of the molded housing 2 is the end surface of the housing 2 close to its opening end. Fig. 9 As shown, in some embodiments, the outer circumference of the first part 101 of the mold core 10 is provided with a circle of steps 33, and the steps 33 abut against the lower end surface 25 of the molded shell 2. A circle of ejector plate mounting surfaces 34 are provided on the outer circumference of the mold core 10 and below the side surface 32. The ejector plate mounting surface 34 can be parallel to the side surface 32, and the ejector plate 41 is sleeved on the outer circumference of the ejector plate mounting surface 34. The ejector plate mounting surface 34 protrudes a distance relative to the side surface 32 in the horizontal direction away from the slide groove 103, so that a step 33 is formed at the connection between the ejector plate mounting surface 34 and the side surface 32. The lower end surface 25 of the molded shell 2 abuts against the step 33, and the ejector plate 41 sleeved on the ejector plate mounting surface 34 applies an upward thrust to the lower end surface 25 of the molded shell 2, so that the shell 2 can be ejected. Therefore, the step 33 can facilitate the ejector plate 41 to eject the shell 2.

[0050] It can be understood that the above embodiments only express the preferred implementation methods of the present application, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application; it should be pointed out that for ordinary technicians in this field, without departing from the concept of the present application, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the present application; therefore, all equivalent changes and modifications made to the scope of the claims of the present application should fall within the scope of the claims of the present application.
