[0044] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] Example 1

[0046] like Figures 1-6 As shown, this embodiment provides a demolding mechanism, which includes a support base 1, a large slider base 2, a first power component 11, a large slider insert 3, a small slider insert 4, a small slider base 5, and a second power component 21. The large slider base 2 is slidably disposed on the support base 1 along a first direction; the first power component 11 is fixedly disposed on the support base 1, and the output end of the large slider base 2 and the first power component 11 are connected; the large slider insert 3 is fixedly disposed at one end of the large slider base 2, and the large slider insert 3 has a notch 31. The small slider insert 4 is slidably disposed on the notch 31 along a second direction; the first and second directions are not parallel, preferably, the second direction is perpendicular to the first direction. The small slider insert 4 has an injection position for injection molding and a demolding position for demolding; the small slider insert 4 has an inner clamping mold 400 on one side along the second direction, wherein the inner clamping mold 400 extends along the second direction and is used to prepare a groove-shaped inner clamping structure for the product. The small slider seat 5 is slidably disposed on the large slider seat 2 along the first direction and is connected to the small slider insert 4 for transmission, and is used to drive the small slider insert 4 to switch from the injection position to the demolding position. The second power component 21 is used to drive the small slider seat 5 to slide.

[0047] In this embodiment, the demolding mechanism drives the large slider insert 3 to move along a first direction via a first power component 11. The large slider insert 3 has a notch 31, and the small slider insert 4 slides along a second direction within the notch 31. The small slider insert 4 is moved from the injection position to the demolding position via a small slider seat 5. During demolding, the small slider insert 4 is first driven to the demolding position via the small slider seat 5. Then, the large slider insert 3 is driven away from the groove structure of the product via the first power component 11, thus completing the demolding process. This invention has a compact structure and high demolding efficiency.

[0048] Furthermore, the small slider seat 5 and the large slider seat 2 are slidably connected, allowing the small slider seat 5 to move stably. Therefore, it provides a stable driving force for the position switching of the small slider insert 4, enabling it to switch from the injection position to the demolding position. The small slider seat 5 slides along the first direction, making the sliding directions of the small slider seat 5 and the large slider seat 2 consistent, further improving the compactness of the structure in this embodiment.

[0049] In this embodiment, optionally, the demolding mechanism further includes a connecting slider 6, which is slidably disposed in the notch 31 along a first direction. One end of the connecting slider 6 is fixedly connected to the small slider seat 5, and the connecting slider 6 and the small slider insert 4 are slidably connected through a dovetail groove structure. The side of the connecting slider 6 facing the small slider insert 4 is an inclined surface 61, which is inclined away from the small slider seat 5 and away from the inner mold 400. With the above configuration, when the connecting slider 6 moves away from the large slider insert 3, it will drive the small slider insert 4 to move towards the center of the groove of the product. When the connecting slider 6 moves closer to the large slider insert 3, it will drive the small slider insert 4 to move towards the edge of the groove of the product. That is, the connecting slider 6 can switch the small slider insert 4 between the injection position and the demolding position.

[0050] Of course, in other embodiments, the small slider seat 5 and the small slider insert 4 can be connected by a rope. When the small slider seat 5 moves away from the large slider insert 3, the small slider insert 4 is pulled along the second direction to the demolding position. In this embodiment, a spring element is also provided between the small slider insert 4 and the large slider insert 3. The spring element is used to reset the small slider insert 4 to the injection position.

[0051] In this embodiment, regarding the structure of the small slider insert 4, specifically, the small slider insert 4 includes two upper slider inserts 41 and one lower slider insert 42. The upper slider inserts 41 are slidably disposed in the upward-opening notch 31 along the second direction, and the lower slider insert 42 is slidably disposed in the downward-opening notch 31 along the second direction. Both the upper slider inserts 41 and the lower slider insert 42 are provided with an inner clamping mold 400. The upper slider inserts 41 and the lower slider insert 42 are slidably connected to the connecting slider 6. With the above arrangement, the upper slider inserts 41 and the lower slider insert 42 can be driven simultaneously, improving the demolding efficiency.

[0052] Optionally, the second power component 21 includes an elastic element, which abuts against the large slider seat 2 and the small slider seat 5, and drives the small slider seat 5 to stop the small slider insert 4 in the demolding position. The elastic element allows the small slider seat 5 to move away from the large slider insert 3 without requiring additional power, thus saving energy.

[0053] Furthermore, the large slider seat 2 is provided with a first mounting groove, and the small slider seat 5 is provided with a second mounting groove; the elastic element is a spring, with both ends of the spring located in the first mounting groove and the second mounting groove, respectively. This configuration improves the installation efficiency of the spring.

[0054] Furthermore, the sum of the depth dimensions of the first mounting slot and the second mounting slot is greater than the total length dimension of the spring after compression. This arrangement prevents damage to the spring when the small slider seat 5 and the large slider seat 2 come into contact.

[0055] In this embodiment, optionally, the demolding mechanism further includes a small slider lever 7. The small slider seat 5 is provided with an insertion hole 51, and the large slider seat 2 is provided with a fixing hole 24. The small slider lever 7 can pass through the insertion hole 51 and be inserted into the fixing hole 24 to lock the small slider insert 4 in the injection position. This setting can lock the small slider seat 5 to the large slider seat 2, avoiding the elastic element from driving the small slider seat 5 during the injection process to switch the small slider insert 4 to the demolding position, thus improving the reliability of the equipment.

[0056] Regarding the structure of the insertion hole 51, in this embodiment, the insertion hole 51 is further inclined from bottom to top towards the large slider insert 3, that is, the center line of the insertion hole 51 is a diagonal line, and the diagonal line is inclined from bottom to top towards the large slider insert 3. When the small slider lever 7 is inserted from top to bottom, the small slider seat 5 moves towards the large slider insert 3. With the above setting, the small slider seat 5 can move towards the large slider insert 3 during the process of the small slider lever 7 being inserted from top to bottom into the insertion hole 51, so as to drive the small slider insert 4 to switch to the injection position. The small slider lever 7 can not only lock the small slider seat 5, but also drive the small slider seat 5 to the end of the large slider seat 2 close to the large slider insert 3. At this time, the small slider insert 4 is in the injection position, realizing multiple uses of one item and improving the injection efficiency.

[0057] Optionally, the first power component 11 includes a pull rod cylinder, which is fixedly mounted on the support base 1, and the output end of the pull rod cylinder is fixedly connected to the large slider seat 2. Preferably, a limiting block 12 is provided at one end of the support base 1 near the first power component 11 to limit the movement limit position of the large slider seat 2.

[0058] Preferably, the demolding mechanism further includes a connecting block 22 and a fixing block 23. The connecting block 22 is fixedly connected to the large slider seat 2, and the fixing block 23 is fixedly connected to the connecting block 22. The connecting block 22 and the fixing block 23 form a through hole. The small slider insert 4 is provided with a demolding sliding part 401, which is slidably disposed in the through hole. The above arrangement enables the detachable assembly of the through hole, facilitating the installation of the small slider insert 4.

[0059] Example 2

[0060] refer to Figure 7 This embodiment also provides a mold, including a male mold 100, a female mold 200, and the demolding mechanism described above. A small slider block 7 is fixed to the male mold 100; a support base 1 is fixed to the female mold 200. When the male mold 100 moves away from the female mold 200, the small slider block 7 is pulled out from the insertion hole 51 of the small slider seat 5. This arrangement enables the small slider seat 5 to move away from the large slider insert 3 under the action of the elastic element during mold opening, and drives the small slider insert 4 to the demolding position, thus improving demolding efficiency.

[0061] Furthermore, the mold also includes a stop block 101, which is located on the male mold 100. When the male mold 100 and the female mold 200 are closed, the stop block 101 abuts against the end of the small slider seat 5 away from the large slider insert 3. This arrangement ensures that before the mold is opened, the small slider seat 5 is held in place by the stop block 101, preventing the small slider seat 5 from moving away from the large slider insert 3 under the action of the elastic element due to the failure of the small slider lever 7, thus improving the reliability of mold production.

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
