[0017] Preferably, a cooling hole is provided at one end of the core-pulling die base away from the slider.
[0018] By adopting the above technical solution and providing cooling holes, cooling liquid can be introduced into the core-pulling mold base, thereby improving the injection molding effect of the shell.

[0034] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0035] The following is combined with Figure 2-6 This application is described in further detail.
[0036] The embodiment of the present application discloses a core-pulling die head.
[0037] Reference Figure 2 and Figure 3 The core-pulling die head includes a core-pulling die base 1, a core-pulling module 2 and a connector 3. A notch 11 is provided on the peripheral side of one end of the core-pulling die base 1. A slider 12 is formed on the core-pulling die base 1 at the notch 11, and the slider 12 is tilted. The shape of the core-pulling module 2 is adapted to the shape of the notch 11. A chute 21 is provided on the side close to the core-pulling die base 1. The chute 21 extends to both ends of the core-pulling module 2, and the slider 12 is slidably connected to the chute 21. At the same time, a limiting groove 22 is provided on the core-pulling module 2 along the length direction of the slider 12. The limiting groove 22 extends to the end of the core-pulling module 2 away from the core-pulling die base 1, and the limiting groove 22 is connected to the chute 21. The connector 3 is vertically fixedly connected to the side of the slider 12 close to the core-pulling module 2, and the connector 3 is limited in the limiting groove 22.
[0038] After the shell 7 is injection molded, the cylinder pulls out the core-pulling die head. The core-pulling module 2 is stationary first, and the cylinder drives the core-pulling module 2 to move, so that the slider 12 slides and connects in the slide groove 21. After the core-pulling module 2 moves a certain distance, that is, after the core-pulling die head completes the first core-pulling work, since the connecting head 3 is limited in the limiting groove 22, the connecting head 3 abuts against the end of the limiting groove 22, so that the core-pulling module 2 moves with the core-pulling die base 1, so that the core-pulling module 2 has a certain movable space, so as to be able to detach from the shell 7 and complete the second core-pulling work of the core-pulling die head, thereby realizing two core pullings of the core-pulling die head, thereby facilitating the extraction of the core-pulling die head.
[0039] In some embodiments, the connector 3 is detachably connected to the slider 12. When assembling the core-pulling die head, the slider 12 is first connected to the slide groove 21 so that the core-pulling module 2 abuts against the notch 11, and then the connector 3 is installed on the slider 12 so that the connector 3 is limited in the limiting groove 22, which facilitates the assembly between the core-pulling die base 1, the core-pulling module 2 and the connector 3.
[0040] In some embodiments, the connector 3 is threadedly connected to the slider 12 so that the connector 3 can be detachably connected to the slider 12. The connector 3 can be installed and removed by rotating the connector 3, which has a simple structure and is easy to operate.
[0041] In some embodiments, a clearance groove 23 is formed at one end of the core pulling module 2 away from the core pulling mold base 1. The clearance groove 23 is connected to the limiting groove 22 to provide a clearance for the connector 3. Specifically, when the core pulling module 2 abuts the notch 11, the connector 3 passes through the clearance groove 23 and can be threadedly connected to the slider 12, so that the connector 3 can be rotated, thereby facilitating the installation and removal of the connector 3.
[0042] Reference Figure 2 and Figure 4 In some embodiments, a positioning post 13 is formed on one end of the core-pulling die base 1 near the slider 12. The positioning post 13 is configured in a conical shape to position the core-pulling die base 1 at the injection molding position to ensure the injection molding effect of the housing 7. In this embodiment, the housing 7 uses two oppositely disposed core-pulling die heads, and the positioning post 13 of the core-pulling die base 1 in one core-pulling die head is inserted into the clearance groove 23 of the core-pulling module 2 in the other core-pulling die head to achieve positioning of the core-pulling die heads.
[0043] Reference Figure 5 In some embodiments, a connecting groove 14 is provided at one end of the core-pulling mold base 1 away from the slider 12. The connecting groove 14 is arranged in a "convex" shape to facilitate the connection between the cylinder and the core-pulling mold base 1, thereby facilitating the extraction and insertion of the core-pulling mold base 1.
[0044] In some embodiments, a cooling hole 15 is provided at one end of the core-pulling mold base 1 away from the slider 12 , so that cooling liquid can flow into the core-pulling mold base 1 , thereby improving the injection molding effect of the housing 7 .
[0045] The implementation principle of this embodiment is: after the shell 7 is injection molded, the cylinder pulls out the core-pulling die head. The core-pulling module 2 is stationary first, and the cylinder drives the core-pulling module 2 to move, so that the slider 12 slides and connects in the slide groove 21. After the core-pulling module 2 moves a certain distance, that is, after the core-pulling die head completes the first core-pulling work, since the connecting head 3 is limited in the limiting groove 22, the connecting head 3 abuts against the end of the limiting groove 22, so that the core-pulling module 2 moves with the core-pulling die base 1, so that the core-pulling module 2 has a certain activity space, so as to be able to detach from the shell 7 and complete the second core-pulling work of the core-pulling die head, thereby realizing two core pullings of the core-pulling die head, thereby facilitating the extraction of the core-pulling die head.
[0046] The embodiment of the present application also discloses a core-pulling mold.
[0047] Reference Figure 6The core-pulling mold includes an upper mold 4, a lower mold 5, two driving members 6, and the two core-pulling die heads described above. The two core-pulling die heads are arranged opposite each other, and an injection cavity (not shown in the figure) is formed between the upper mold 4, the lower mold 5, and the two core-pulling die heads. The two driving members 6 are respectively fixedly connected to the two ends of the lower mold 5, and the power output shafts are respectively fixedly connected to the two connecting grooves 14. The driving member 6 can be, but is not limited to, a pneumatic cylinder, an oil cylinder, an electric push cylinder, etc.
[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
