[0058] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0059] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0060] This invention provides a mold structure that enables convenient molding and demolding of products with undercuts, such as power buttons and function keys in electronic products.

[0061] like Figure 1 , Figure 2 and Figure 7 As shown, the mold structure provided in this embodiment of the invention includes:

[0062] A first mold 1 and a second mold 2 are movably connected. The first mold 1 has a through hole 11, and the second mold 2 has a first groove 21, which is opposite to the through hole 11.

[0063] The movable component 3 is movably disposed within the through hole 11 of the first mold 1 and can move in a direction close to or away from the first groove 21;

[0064] The push rod 4, the first mold 1 is also provided with a second groove 13, the second groove 13 is connected to the through hole 11, and the push rod 4 is movably disposed in the second groove 13;

[0065] When the push rod 4 moves in the first direction, the push rod 4 approaches the movable component 3 and can push the movable component 3 to move so that part of the movable component 3 enters the first groove 21, and the movable component 3, the first mold 1 and the second mold 2 form a molding area; when the push rod 4 moves in the second direction, the push rod 4 moves away from the movable component 3, and the movable component 3 can return to the through hole 11, and the second direction is opposite to the first direction.

[0066] like Figure 1 , Figure 13 and Figure 14 As shown, the mold structure provided in this embodiment of the invention includes a first mold 1 and a second mold 2. The first mold 1 is also known as the male mold, and the second mold 2 is also known as the female mold. The movement of the first mold 1 within the second mold 2 enables the molding and demolding of the product. Specifically, a through hole 11 is formed on the first mold 1, and a corresponding first groove 21 is provided on the second mold 2, such as... Figures 18 to 20 As shown, the first groove 21 and the through hole 11 are positioned opposite each other, that is, the through hole 11 on the first mold 1 can be connected with the first groove 21 on the second mold 2, so that the movable component 3 located in the first mold 1 can extend into the first groove 21 from the through hole 11, thereby realizing the convenient molding of products with undercuts.

[0067] like Figures 1 to 6 As shown, in this embodiment of the invention, the movable component 3 is movably disposed within the through hole 11 of the first mold 1, and the movable component 3 is configured to move in a direction close to or away from the first groove 21 under the action of the push rod 4. For example, the movable component 3 can slide into the first groove 21, or the movable component 3 can rotate into the first groove 21, both of which can together with the first mold 1 and the second mold 2 form a molding area with an undercut, so as to realize the convenient molding of products with undercuts.

[0068] Specifically, when push rod 4 moves in the first direction (e.g.) Figure 2 and Figure 3In the case of (moving from center to right), push rod 4 can approach movable component 3 and push movable component 3 to move so that a part of movable component 3 enters the first groove 21. For example, when movable component 3 can slide under the pushing force of push rod 4, a part of movable component 3 enters the first groove 21, which means that during the sliding process of movable component 3, the part of movable component 3 close to the first groove 21 slides into the first groove 21; while when movable component 3 can rotate under the pushing force of push rod 4, a part of movable component 3 enters the first groove 21, which means that during the rotation of movable component 3, the end of movable component 3 away from push rod 4 rotates into the first groove 21. In both cases, movable component 3, first mold 1 and second mold 2 can together form a molding area with an undercut, such as Figure 4 As shown, this facilitates the easy molding of products with undercuts.

[0069] As push rod 4 moves in the second direction (for example) Figure 5 and Figure 6 In the case of (moving from center to left), push rod 4 can move away from movable component 3 to cancel the thrust acting on movable component 3, and movable component 3 can return to the through hole 11. For example, movable component 3 can return to the through hole 11 of the first mold 1 under the drive of elastic force, so as to facilitate the sequential and convenient removal of the first mold 1 and the product with the undercut. Figure 6 This ensures the molding efficiency and reliability of the mold structure. Furthermore, the mold structure is simple, the molding process is convenient and controllable, and the molding efficiency is excellent, making it suitable for mass production of products with undercuts.

[0070] Optionally, the movable component 3 includes a movable part 31 and a first elastic member 32. The movable part 31 includes a first movable part and a second movable part. Both the first movable part and the second movable part are movably disposed in the through hole 11, and the first elastic member 32 is connected between the first movable part and the second movable part.

[0071] When the push rod 4 moves in the first direction, the push rod 4 pushes the movable member 31 so that at least one of the first movable part and the second movable part can slide into the first groove 21, and the first elastic member 32 is stretched; when the push rod 4 moves in the second direction, the push rod 4 moves away from the movable member 31, and the first elastic member 32 can elastically reset so that the movable member 31 returns to the through hole 11.

[0072] like Figure 7 and Figure 8As shown, the movable component 3 in this embodiment of the invention may include a movable member 31 and a first elastic member 32. The movable member 31 can move within the through hole 11 and extend into the first groove 21 under the action of the push rod 4, stretching the first elastic member 32 to undergo elastic deformation. At this time, the first elastic member 32 has a first stretching amount. After the pushing force of the push rod 4 is removed, the first elastic member 32 can elastically reset and drive the movable member 31 back into the through hole 11, thereby facilitating the sequential and convenient removal of the first mold 1 and the product with the undercut. At this time, the first elastic member 32 may have a second stretching amount, that is, the first elastic member 32 can still be in a stretched state, wherein the second stretching amount is less than the first stretching amount, so that the first elastic member 32 is slightly stretched, thereby improving the connection reliability between the first movable part and the second movable part; the first elastic member 32 may also be in its original state, that is, the first elastic member 32 is not under force, thereby extending the service life of the first elastic member 32. Two or more first elastic members 32 can be connected between the first movable part and the second movable part to enhance the elastic driving effect between the first movable part and the second movable part.

[0073] Specifically, in this embodiment of the invention, the movable component 31 may include a first movable part and a second movable part (e.g., Figures 21 to 24 The diagram shows different angles of the first and / or second movable parts. The first and second movable parts are disposed opposite each other within the through hole 11, and a first elastic element 32 connects the first and second movable parts. When the push rod 4 moves along a first direction (e.g., ...), Figure 2 and Figure 3 In the case of (moving from center to right), push rod 4 can push movable part 31 so that at least one of the first movable part and the second movable part can slide into the first groove 21. For example, only part of the first movable part can slide into the first groove 21, at which time the second movable part is stationary, and the first groove 21 is opened on the side of the second mold 2 near the first movable part, while the side of the second mold 2 near the second movable part is not slotted; or only part of the second movable part can slide into the first groove 21, at which time the first movable part is stationary, and the first groove 21 is opened on the side of the second mold 2 near the second movable part, while the side of the second mold 2 near the first movable part is not slotted; or part of the first movable part and part of the second movable part can slide into the first groove 21 respectively, at which time the second mold 2 is provided with two first grooves 21 opposite to each other.

[0074] Furthermore, the arrangement of the first groove 21 on the second mold 2 can accommodate various types of products with undercuts. For example, if the product has an undercut on only one side, the first groove 21 can be provided on only one side of the second mold 2, so that the movement of one of the first and second movable parts can form a molding area with the first mold 1 and the second mold 2; if the product has undercuts on both sides, the first groove 21 needs to be provided on both sides of the second mold 2 accordingly, so that the movement of the first and second movable parts can form a molding area with the first mold 1 and the second mold 2. The first and second movable parts can be structures such as sliders or sliding tables.

[0075] While the push rod 4 moves in the second direction (for example) Figure 5 and Figure 6 When the push rod 4 moves away from the movable part 31 (from center to left), the pushing force acting on the movable part 31 can be canceled. At this time, the first elastic element 32 can elastically reset and drive the movable part 31 (first movable part and / or second movable part) back into the through hole 11, so as to facilitate the sequential and convenient removal of the first mold 1 and the product with the undercut.

[0076] Optionally, the second mold 2 is provided with two first grooves 21 opposite to each other. The two first grooves 21 are respectively connected to the through hole 11. The first movable part and the second movable part can slide into the two first grooves 21 respectively, and the sliding directions of the first movable part and the second movable part are opposite.

[0077] Specifically, in this embodiment of the invention, two first grooves 21 are provided opposite to each other on the second mold 2, and both first grooves 21 can communicate with the through hole 11, so that the parts of the first movable part and the second movable part can slide into the two first grooves 21 respectively, thereby realizing convenient molding of products with undercuts. The sliding directions of the first movable part and the second movable part are opposite, so that the first movable part and the second movable part can slide into the first groove 21 together under the pushing force of the push rod 4, and can also slide out together after the pushing force of the push rod 4 is removed, thereby realizing convenient molding and convenient removal of products with undercuts.

[0078] Optionally, the first movable part has a first inclined portion 33 on the side near the second movable part, and the second movable part has a second inclined portion 34 on the side near the first movable part. When the push rod 4 moves in the first direction, the push rod 4 can push the first movable part along the first inclined portion 33 so that a portion of the first movable part slides into a first groove 21; and the push rod 4 can push the second movable part along the second inclined portion 34 so that a portion of the second movable part slides into another first groove 21. The first movable part, the second movable part, the first mold 1 and the second mold 2 form a molding area.

[0079] like Figure 7 and Figure 8 As shown, in this embodiment of the invention, the first movable part has a first inclined part 33 on the side near the second movable part, and the second movable part has a second inclined part 34 on the side near the first movable part, so that the surfaces in contact with the first movable part, the second movable part and the push rod 4 can all be inclined surfaces, so that the horizontal thrust of the push rod 4 can be converted into a vertical force by using the inclined surfaces, thereby facilitating the sliding of the first movable part and the second movable part into the first groove 21 respectively.

[0080] Specifically, when push rod 4 moves in the first direction (e.g.) Figure 2 and Figure 3 When the push rod 4 moves to the right, it approaches the first movable part and can push the first movable part along the first inclined part 33 so that part of the first movable part slides into a corresponding first groove 21. At the same time, the push rod 4 also approaches the second movable part and can push the second movable part along the second inclined part 34 so that part of the second movable part slides into another corresponding first groove 21. At this time, the first movable part, the second movable part, the first mold 1 and the second mold 2 together form a molding area. By injecting liquid molding material and cooling it, a product with an undercut can be formed.

[0081] Optionally, the first movable part and the second movable part have the same structure and are arranged symmetrically.

[0082] Specifically, in embodiments of the present invention, the first movable part and the second movable part can be designed to have identical structures, facilitating their interchangeability and reducing mold opening costs and production difficulty. Furthermore, the identical and symmetrical arrangement of the first and second movable parts facilitates convenient control of their synchronous movement using the push rod 4, thereby improving the molding convenience and efficiency of the mold structure.

[0083] Optionally, the movable component 3 further includes a rotating member 35 and a second elastic member 36. The rotating member 35 includes a first rotating part and a second rotating part, and one end of the first rotating part and one end of the second rotating part are connected to the through hole 11. The other end of the first rotating part and the other end of the second rotating part are connected to the second elastic member 36.

[0084] When the push rod 4 moves in the first direction, the push rod 4 pushes the rotating member 35 so that the other end of at least one of the first rotating part and the second rotating part can rotate into the first groove 21, and the second elastic member 36 is stretched; when the push rod 4 moves in the second direction, the push rod 4 moves away from the rotating member 35, and the second elastic member 36 can elastically reset so that the rotating member 35 returns to the through hole 11.

[0085] like Figures 9 to 12As shown, in this embodiment of the invention, the movable component 3 may further include a rotating member 35 and a second elastic member 36. The rotating member 35 can rotate within the through hole 11 under the action of the push rod 4 and rotate to one side into the first groove 21, simultaneously stretching the second elastic member 36 to cause elastic deformation. At this time, the second elastic member 36 may have a first stretching amount. After the pushing force of the push rod 4 is removed, the second elastic member 36 can elastically reset and drive the rotating member 35 back into the through hole 11, thereby facilitating the sequential and convenient removal of the first mold 1 and the product with the undercut. At this time, the second elastic member 36 may have a second stretching amount, that is, the second elastic member 36 can still be in a stretched state, wherein the second stretching amount is less than the first stretching amount, so that the second elastic member 36 is slightly stretched, thereby improving the connection reliability between the first rotating part and the second rotating part; the second elastic member 36 may also be in its original state, that is, the second elastic member 36 is not under force, thereby extending the service life of the second elastic member 36.

[0086] Specifically, in this embodiment of the invention, the rotating member 35 may include a first rotating part and a second rotating part (e.g., Figures 25 to 28 (The diagram shows different angles of the first rotating part and / or the second rotating part). The first rotating part and the second rotating part are disposed opposite to each other in the through hole 11, and one end of the first rotating part and one end of the second rotating part are movably connected in the through hole 11. A second elastic member 36 is connected between the other end of the first rotating part and the other end of the second rotating part, so that the first rotating part and the second rotating part can rotate and stretch the second elastic member 36 under the pushing force of the push rod 4.

[0087] As push rod 4 moves in the first direction (e.g.) Figure 2 and Figure 3 In the case of (moving from center to right), push rod 4 can push rotating part 35 so that the other end of at least one of the first rotating part and the second rotating part can rotate into the first groove 21. For example, only the other end of the first rotating part can slide into the first groove 21, at which time the second rotating part is stationary (ignoring the compression of the second rotating part). The first groove 21 is opened on the side of the second mold 2 near the first rotating part, while the side of the second mold 2 near the second rotating part is not slotted. Alternatively, only the other end of the second rotating part can rotate into the first groove 21, at which time the first rotating part is stationary (ignoring the compression of the first rotating part). The first groove 21 is opened on the side of the second mold 2 near the second rotating part, while the side of the second mold 2 near the first rotating part is not slotted. Alternatively, the other ends of the first rotating part and the other ends of the second rotating part can respectively rotate into the first groove 21. At this time, two first grooves 21 are provided opposite to each other on the second mold 2.

[0088] The arrangement of the first groove 21 on the second mold 2 can accommodate various types of products with undercuts. For example, if the product has an undercut on only one side, the first groove 21 can be set on only one side of the second mold 2, so that the rotation of one of the first rotating part and the second rotating part can form a molding area with the first mold 1 and the second mold 2. If the product has undercuts on both sides, the first groove 21 needs to be set on both sides of the second mold 2, so that the synchronous rotation of the first rotating part and the second rotating part can form a molding area together with the first mold 1 and the second mold 2.

[0089] While the push rod 4 moves in the second direction (for example) Figure 5 and Figure 6 When the push rod 4 moves away from the rotating part 35 (from center to left), the pushing force acting on the rotating part 35 can be canceled. At this time, the second elastic element 36 can elastically reset and drive the rotating part 35 (first rotating part and / or second rotating part) back into the through hole 11, so as to facilitate the sequential and convenient removal of the first mold 1 and the product with the undercut.

[0090] Optionally, the second mold 2 is provided with two first grooves 21 opposite to each other. The two first grooves 21 are respectively connected to the through hole 11. The other end of the first rotating part and the other end of the second rotating part can be rotated into the two first grooves 21 respectively. The rotation directions of the first rotating part and the second rotating part are opposite.
