The second mold includes a protruding part that protrudes compared with the second surface, and the protruding part is located on one side of the second molding part; wherein, after the first mold and the second mold are closed, the second molding part is docked with the first molding part and they jointly enclose to form a cavity, and the protruding part is docked with the recessed part and they jointly enclose to form a gate runner, and the gate runner is communicated with the cavity.

[0007] According to an embodiment of this application, a receiving groove is recessed on one side of the protruding part away from the second surface, and the gate runner at least includes the receiving groove.

[0008] According to an embodiment of this application, the receiving groove includes a main groove part, a submersible gate groove part and an ejection groove part that are respectively communicated with the main groove part. The main groove part is located inside the protruding part. The second molding part has a molding groove. The submersible gate groove part extends from the main groove part to communicate with the molding groove, and the ejection groove part extends from the main groove part to the outside of the molding groove and is not communicated with the molding groove.

[0009] According to an embodiment of this application, the submersible gate groove part extends linearly from inside the protruding part to communicate with the molding groove. The extending direction of the submersible gate groove part is set at an angle with the second surface, and the inner diameter of the submersible gate groove part decreases with the increase of the distance from the protruding part to the molding groove in the extending direction of the submersible gate groove part.

[0010] According to an embodiment of the present application, the protruding portion extends to the edge of the second surface, and the protruding portion is a strip-shaped protrusion extending from the forming groove to the edge of the second surface;

[0011] The orthographic projection of the main body groove portion on the second surface extends along the extending direction of the protruding portion, the orthographic projection of the submersible gate groove portion on the second surface also extends along the extending direction of the protruding portion, and the extending direction of the ejection groove portion is perpendicular to the second surface.

[0012] According to an embodiment of the present application, the recessed portion is further recessed to form a groove that can be docked with the receiving groove. After the first mold and the second mold are clamped, the groove and the receiving groove jointly form a gate runner.

[0013] According to an embodiment of the present application, the injection mold further includes an ejection device. The ejection device penetrates through the second mold. The ejection device includes a first ejection mechanism. The first ejection mechanism extends to the ejection groove portion. The first ejection mechanism can move relative to the second mold to eject the waste material in the receiving groove.

[0014] According to an embodiment of the present application, the injection mold further includes an ejection device. The ejection device penetrates through the second mold. The ejection device includes a second ejection mechanism. The second ejection mechanism extends to the bottom of the forming groove. The second ejection mechanism can move relative to the second mold to eject the injection molded product in the forming groove.

[0017] The beneficial effects of the present application are:

[0018] For the injection mold provided by the present application, since the gate runner is communicated with the mold cavity, the thermally melted liquid injection molding material in the gate runner can enter the mold cavity through the communication part between the gate runner and the mold cavity to fill the mold cavity. After the thermally melted liquid injection molding material filled in the mold cavity is shaped, the final injection molded product is formed. And in the present application, the gate runner is formed by docking and jointly enclosing the protruding portion and the recessed portion. Compared with directly forming the gate runner by recessing the first surface of the first mold and the second surface of the second mold, the position of the gate runner is raised. Without changing the structure of the first molding part of the first mold and the structure of the gate runner, by raising the height of the gate runner, the distance between the second surface of the second mold and the bottom of the mold cavity can be reduced. Therefore, the rib length or the product thickness of the injection molded product formed in the mold cavity can be reduced. Description of the Drawings

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] Referring to "embodiments" herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0033] Please refer to Figures 1 to 3 , Figure 1 , which is a perspective view of an exemplary embodiment of an injection mold provided by the present application. Figure 2 is Figure 1 an exploded schematic view of the injection mold. Figure 3 is Figure 1 a cross-sectional schematic view of the injection mold. The injection mold 10 includes a first mold 100 and a second mold 200.

[0034] Referring to together Figure 4 , Figure 4 is Figure 1 and Figure 2 a perspective schematic view of the first mold 100 in the injection mold 10. The first mold 100 has a first surface 101, and a first molding portion 110 is formed on the first surface 101. The first mold 100 includes a recessed portion 120 that is recessed compared to the first surface 101, and the recessed portion 120 is located on one side of the first molding portion 110.

[0035] Referring to together Figure 5 , Figure 5 is Figure 1 and Figure 2 a perspective schematic view of the second mold 200 in the injection mold 10. The second mold 200 has a second surface 201 corresponding to the first surface 101, and a second molding portion 210 is formed on the second surface 201. The second mold 200 includes a protruding portion 220 that protrudes compared to the second surface 201, and the protruding portion 220 is located on one side of the second molding portion 210.

[0036] Among them, after the first mold 100 and the second mold 200 are closed, the second molding part 210 is butted against the first molding part 110 and they jointly enclose to form a mold cavity 10A. The convex part 220 is butted against the concave part 120 and they jointly enclose to form a glue inlet runner 021. The glue inlet runner 021 is communicated with the mold cavity 10A.

[0037] In this application, since the glue inlet runner 021 is communicated with the mold cavity 10A, the molten liquid injection molding material in the glue inlet runner 021 can enter the mold cavity 10A through the communication part between the glue inlet runner 021 and the mold cavity 10A to fill the mold cavity 10A. After the molten liquid injection molding material filled in the mold cavity 10A is shaped, the final injection molding product is formed.

[0038] The injection molding product formed in the mold cavity 10A can be such as Figure 6 the structure shown. The injection molding product 20 can be a part of an electronic atomization device. For example, it can be some structural parts in the electronic atomization device that have a physical connection or support function. Figure 3 The mold cavity 10A in Figure 4 the first molding part 110 in Figure 5 the second molding part 210 in Figure 6 and the injection molding product 20 in

[0039] are only examples. They can also be of other shapes or other structures. This application does not make specific limitations in this regard.

[0040] And in this application, the glue inlet runner 021 is formed by the butting and joint enclosure of the convex part 220 and the concave part 120. Please refer to Figure 7 , Figure 7 which Figure 3 is a partial enlarged view of the injection mold 10, Figure 7 showing the formation structure of the glue inlet runner 021. Figure 7 In

[0041] In the related art, please refer to Figure 8 , Figure 8It is a schematic cross-sectional structure diagram of a gating runner in the related art, which directly forms the gating runner 021' by the depression of the first surface of the first mold 100' and the second surface of the second mold 200', rather than forming the gating runner 021 by the docking of the protruding part 220 and the recessed part 120 and their joint enclosure as in the present application. Figure 8 In [reference], D' is the height of the mold cavity 10A' in the second mold 200', that is, the distance between the second surface of the second mold 200' and the bottom of the mold cavity 10A', and it is also the length of the rib of the injection-molded product after molding.

[0042] It can be seen that in the present application, the gating runner 021 is formed by the docking of the protruding part 220 and the recessed part 120 and their joint enclosure. Compared with Figure 8 the related art shown in which the gating runner 021' is directly formed by the depression of the first surface of the first mold 100' and the second surface of the second mold 200' to jointly enclose, the position of the gating runner 021 of the present application is raised relative to the second surface 201, so D is less than D'. Without changing the structure of the first molding part 110 of the first mold 100 and the structure of the gating runner 021 itself in the present application, by raising the height of the gating runner 021, the distance between the second surface 201 of the second mold 200 and the bottom of the mold cavity 10A can be reduced. Therefore, the rib length of the injection-molded product 20 formed in the mold cavity 10A can be reduced. Similarly, when D is the thickness of the injection-molded product 20, the present application can be used to produce injection-molded products 20 with a smaller thickness. For example, products with a thickness or rib length less than 2 mm.

[0043] It should be noted that Figure 3 and Figure 7 In the embodiments shown in [reference], the height of the mold cavity 10A is lower than the height of the gating runner 021, which is only an example. In other embodiments, since the molten material in the gating runner 021 can also be injected into the mold cavity 10A under pressure, the height of the mold cavity 10A can also be higher than the height of the gating runner 021 or the same as the height of the gating runner 021.

[0044] Moreover, the position of the gating runner 021 in the present application is raised. In addition to being applicable to the production of products with a smaller thickness or rib length, such as products with a thickness or rib length less than 2 mm, it can also be applicable to the production of products with a larger thickness or rib length, such as products with a thickness or rib length greater than 2 mm.

[0045] In this application, the meaning of the butting of the protrusion 220 and the recess 120 refers to that the protrusion 220 and the recess 120 can be in contact only on the opposite faces, or in addition to the contact on the opposite faces, the side walls of the protrusion 220 and the recess 120 can also be partially or completely in contact. And the meaning of the contact of the opposite faces of the protrusion 220 and the recess 120 refers to that since the protrusion 220 and the recess 120 jointly enclose the glue inlet runner 021, after the first mold 100 and the second mold 200 are closed, only part of the opposite faces of the protrusion 220 and the recess 120 are in contact, that is, the opposite faces of the protrusion 220 and the recess 120 are not in contact in the area where the glue inlet runner 021 is located, and are in contact in the area outside the glue inlet runner 021.

[0046] Refer to again Figure 3 、 Figure 5 and Figure 7 In an embodiment, a receiving groove 221 is recessed on the side of the protrusion 220 facing away from the second surface 201, and the glue inlet runner 021 at least includes the receiving groove 221. The meaning that the glue inlet runner 021 at least includes the receiving groove 221 refers to that the space occupied by the glue inlet runner 021 can be only the space occupied by the receiving groove 221, or in addition to the space occupied by the receiving groove 221, the space occupied by the glue inlet runner 021 also includes the space occupied by other recessed areas formed by the recess 120 being recessed compared to the butting surface of the protrusion 220 and the recess 120.

[0047] Refer to again Figure 3 、 Figure 4 and Figure 7 In an embodiment, the recess 120 is further recessed to form a groove 121 that can be butted with the receiving groove 221. After the first mold 100 and the second mold 200 are closed, the groove 121 and the receiving groove 221 are butted to jointly form the glue inlet runner 021. In this embodiment, the groove 121 formed by the recess 120 on the first mold 100 constitutes a part of the glue inlet runner 021, and the receiving groove 221 formed by the protrusion 220 on the second mold 200 constitutes another part of the glue inlet runner 021. It can be understood that in other embodiments, the space occupied by the glue inlet runner 021 can also be only the space occupied by the receiving groove 221.

[0048] Refer to again Figure 5 and Figure 7, in one embodiment, the receiving groove 221 includes a main groove portion 221A, a submersible gate groove portion 221B and an ejection groove portion 221C that are respectively communicated with the main groove portion 221A. The main groove portion 221A is located within the protruding portion 220. The second molding portion 210 has a molding groove 211. The submersible gate groove portion 221B extends from the main groove portion 221A to communicate with the molding groove 211. The ejection groove portion 221C extends from the main groove portion 221A to the outside of the molding groove 211 and is not communicated with the molding groove 211.

[0049] The submersible gate groove portion 221B communicates the main groove portion 221A with the molding groove 211. The connection between the submersible gate groove portion 221B and the molding groove 211 is the gate 212, and the gate 212 is also called the sprue. The meaning of the gate 212 / sprue refers to the inlet and outlet of the thermally molten injection molding material. The thermally molten injection molding material can enter the molding groove 211 through the gate 212, that is, enter the mold cavity 10A. After the injection molding is completed, the molten material in the injection runner 021 will solidify to form a waste 30, and the shape of the waste 30 is consistent with the shape of the injection runner 021.

[0050] The groove 121 and the main groove portion 221A of the receiving groove 221 can be semi-cylindrical respectively. When the groove 121 and the main groove portion 221A of the receiving groove 221 are butted, a whole cylindrical cavity structure can be formed. Therefore, when the second mold 200 is demolded, the first mold 100 is more likely to be separated from the waste 30 in the injection runner 021, so that the waste 30 remains in the receiving groove 221 of the second mold 200 and moves synchronously with the second mold 200. At the same time, the ejection device 400 described later can also more easily eject the waste 30 from the receiving groove 221.

[0051] Continue to refer to Figure 7 , in one embodiment, the submersible gate groove portion 221B extends linearly from within the protruding portion 220 to communicate with the molding groove 211. The extending direction of the submersible gate groove portion 221B is arranged at an angle with the second surface 201, and the inner diameter of the submersible gate groove portion 221B decreases with the increase of the distance from the protruding portion 220 to the molding groove 211 in the extending direction of the submersible gate groove portion 221B. In this embodiment, the submersible gate groove portion 221B adopts this inclined trumpet-shaped structure, and the molten material in the main groove portion 221A can more easily flow into the mold cavity 10A under the action of its own gravity.

[0052] Refer to again Figure 5 and Figure 7 , in one embodiment, the protruding portion 220 extends to the edge of the second surface 201, and the protruding portion 220 is a strip-shaped protrusion extending from the molding groove 211 to the edge of the second surface 201. Correspondingly, the recessed portion 120 also extends to the edge of the first surface 101.

[0053] The orthographic projection of the main body groove portion 221A on the second surface 201 extends along the extension direction of the convex portion 220, and the orthographic projection of the submersible gate groove portion 221B on the second surface 201 also extends along the extension direction of the convex portion 220. The extension direction of the ejection groove portion 221C is perpendicular to the second surface 201.

[0054] In one embodiment, the side wall of the recessed portion 120 includes a first inclined surface 122 that is inclined with respect to the first surface 101, and the side wall of the convex portion 220 includes a second inclined surface 222 that is inclined with respect to the second surface 201. After the first mold 100 and the second mold 200 are clamped, the second inclined surface 222 abuts against or forms an angle with the first inclined surface 122. In this embodiment, since the second inclined surface 222 abuts against or forms an angle with the first inclined surface 122 after the first mold 100 and the second mold 200 are clamped, when the second mold 200 moves away from the first mold 100 for demolding, the convex portion 220 and the recessed portion 120 are more likely to be separated, that is, it is more convenient for demolding.

[0055] Please refer to Figure 9 , Figure 9 FIG. is a three-dimensional schematic diagram of another embodiment of the injection mold provided by the present application. The injection mold 10 further includes an ejection device 400. The ejection device 400 is disposed through the second mold 200. The ejection device 400 includes a first ejection mechanism 410. The first ejection mechanism 410 extends to the ejection groove portion 221C. The top surface of the first ejection mechanism 410 can serve as the bottom of the ejection groove portion 221C. The first ejection mechanism 410 can move relative to the second mold 200 to eject the waste 30 in the receiving groove 221. The first ejection mechanism 410 can adopt the structure of an ejector pin. Usually, after injection molding, there will be waste residue at the gate 212 of the injection molded product 20. When the injection molded product 20 is taken out of the molding groove 211, it is necessary to manually post-process the waste residue at the gate 212 of the injection molded product 20 or specifically design a punching jig for processing, resulting in increased costs and low production efficiency. However, in this embodiment, the ejection device 400 is provided, and the waste 30 in the receiving groove 221 can be ejected from the receiving groove 221 by the first ejection mechanism 410 of the ejection device 400. During the process of the waste 30 being ejected from the receiving groove 221, the waste 30 can be automatically broken / severed from the injection molded product 20 at the gate 212, and there is no need to post-process the waste residue at the gate 212 of the injection molded product 20.

[0056] Refer to again Figure 9, in one embodiment, the ejection device 400 further includes a second ejection mechanism 420. The second ejection mechanism 420 extends to the bottom of the molding groove 211. The second ejection mechanism 420 is capable of moving relative to the second mold 200 to eject the injection molded product in the molding groove 211. After the first mold 100 and the second mold 200 are separated in this embodiment, the injection molded product in the molding groove 211 can be automatically ejected by the second ejection mechanism 420. The second ejection mechanism 420 can also adopt the structure of ejector pins, and there can be multiple ejector pins in the second ejection mechanism 420 to eject the injection molded product at different positions of the injection molded product, so that the injection molded product is more balanced in force and easier to be ejected from the molding groove 211.

[0057] The following briefly describes the working process of the ejection device 400 in the injection mold 10 of the present application.

[0058] After the material in the mold cavity 10A is shaped to form an injection molded product, first, the second mold 200 together with the first ejection mechanism 410 and the second ejection mechanism 420 move synchronously in a direction away from the first mold 100, so that the second mold 200 is separated from the first mold 100, and the injection molded product 20 and the waste 30 on the second mold 200 also move synchronously with the second mold 200. When the second mold 200 moves in place, the second mold 200, the first ejection mechanism 410, and the second ejection mechanism 420 all stop moving. Then the second mold 200 remains stationary, and the first ejection mechanism 410 moves relative to the second mold 200 in a direction close to the first mold 100 to eject the waste 30 in the receiving groove 221 on the second mold 200 from the receiving groove 221, and the second ejection mechanism 420 also moves relative to the second mold 200 in a direction close to the first mold 100 to eject the injection molded product 20 in the molding groove 211 on the second mold 200 from the molding groove 211. To prevent the injection molded product 20 and the waste 30 from falling outside the mold 10 after being ejected, the moving distances of the first ejection mechanism 410 and the second ejection mechanism 420 should not be too large.

[0059] It should be noted that the order of the two processes of the first ejection mechanism 410 ejecting the waste 30 from the receiving groove 221 and the second ejection mechanism 420 ejecting the injection molded product 20 from the molding groove 211 can be arbitrary, that is, the process of the first ejection mechanism 410 ejecting the waste 30 from the receiving groove 221 can be prior, and the process of the second ejection mechanism 420 ejecting the injection molded product 20 from the molding groove 211 can be subsequent; the process of the second ejection mechanism 420 ejecting the injection molded product 20 from the molding groove 211 can be prior, and the process of the first ejection mechanism 410 ejecting the waste 30 from the receiving groove 221 can be subsequent; or the two processes can be carried out simultaneously.

[0060] It should be further noted that the second ejection mechanism 420 and the first ejection mechanism 410 can be driven by different driving mechanisms respectively, or can be driven by the same driving mechanism. In order to simplify the structure of the entire mold 10, the same driving mechanism can be used for driving.

[0061] In the above embodiments, the number of the mold cavities 10A, the convex portions 220, the concave portions 120, and the ejection device 400 can all be one, so that the production of a single injection-molded product can be realized. Further, the number of the mold cavities 10A, the convex portions 220, the concave portions 120, and the ejection device 400 are all the same and are multiple, so as to realize the production of multiple injection-molded products in the same injection mold 10.
