A cooling groove is opened on the top of the cooling seat, and a lower mold is fixedly connected to the bottom of the inner cavity of the cooling groove.

[0005] The aforementioned patent offers advantages such as high molding efficiency and recyclable coolant, solving the problem that existing injection molds for plastic parts processing cannot circulate cooling and heat dissipation, thus affecting molding efficiency. It is known that during injection molding, specific mold cores are typically set on the sidewalls of the mold to meet the molding requirements. However, due to the special structure of the mold cores, demolding is inconvenient. Utility Model Content

[0006] The purpose of this invention is to provide a mold with a moving mold driving a fixed mold tunnel slider core pulling mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mold with a moving mold driving a fixed mold tunnel slider core-pulling mechanism, comprising a mold body, an injection space on the mold body, a mold core slidably connected to the mold body, the mold core communicating with the injection space, and an mounting block on the mold core; further comprising a shovel, the shovel being connected to the mold core via a connecting member; the mold body is also provided with a driving member for driving the mold body to open, during which the driving member drives the shovel to slide downwards, and the mold core slides out of the mold body through the connecting member.

[0008] Furthermore, the connector includes a wedge block fixedly connected to the mounting block, and the shovel has a wedge groove adapted to the wedge block, the wedge block being engaged in the wedge groove.

[0009] Furthermore, it also includes a connecting block on which a support column is mounted, the support column being in communication with the injection molding space.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the mold with the moving mold driving the fixed mold tunnel slider core pulling mechanism can, after the workpiece is injection molded and cooled, drive the moving mold and fixed mold to open. During the opening stroke of the moving mold and fixed mold, the connecting part drives the mold core to slide horizontally in the mold body, thereby allowing the mold core to slide out from the injection space, avoiding the mold core from affecting the subsequent demolding operation, greatly improving the demolding efficiency of the mold and making it more effective.

[0016] Please see Figures 1-2 This utility model provides a technical solution: a mold with a moving mold driving fixed mold tunnel slider core pulling mechanism, including a mold body, an injection space on the mold body, a mold core 1 slidably connected to the mold body, the mold core 1 communicating with the injection space, and an installation block 2 on the mold core 1; it also includes a shovel 4, which is connected to the mold core 1 through a connecting member; the mold body is also provided with a driving member for driving the mold body to open the mold, and when the mold is opened, the driving member drives the shovel 4 to slide downward during the stroke, and the mold core 1 slides out of the mold body through the connecting member.

[0017] Specifically, the mold with a moving mold-driven fixed mold tunnel slider core-pulling mechanism includes a mold body, which specifically includes a moving mold, a fixed mold, and a mold frame. The mold body has an injection space for injection molding of the workpiece. It also has an injection channel for the flow of adhesive, which is connected to the injection space for better injection molding. A mold core 1 is slidably connected to the mold body, communicating with the injection space. The mold core 1 has a mounting block 2 for easy adjustment of its state. The mold also includes a shovel 4, which is connected to the mold core 1 via a connector. The mold body also has a drive component for opening the mold. During opening, the drive component drives the shovel 4 downwards, sliding the mold core 1 out of the mold body via the connector. Therefore, after the workpiece is injection molded and cooled, the driving component drives the moving mold and the fixed mold to open. During the opening stroke of the moving mold and the fixed mold, the connecting component drives the mold core 1 to slide horizontally in the mold body, so that the mold core 1 slides out from the injection space, avoiding the mold core 1 from affecting the subsequent demolding operation, greatly improving the demolding efficiency of the mold and making it more effective.

[0018] In the embodiments provided by this utility model, the connecting member includes a wedge block 3 fixedly connected to the mounting block 2.
