[0001] The utility model belongs to the technical field of connector manufacturing, in particular to a power connector terminal sealing mold. Background Art

[0002] Pin header connector is a connector used to connect electronic devices, usually composed of two parts: pin header and female header. Pin header connector is usually used to connect circuit boards or between circuit boards and external devices to provide reliable electrical connection. This connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its role is to act as a bridge between blocked circuits or isolated circuits within the circuit, and to undertake the task of current or signal transmission.

[0003] During the manufacturing process of the existing pin header connector, the terminal needs to be inserted into the mold core first. After the terminal is sealed and formed, it needs to be pulled out of the mold core. In addition, the existing mold core is generally fixed on the mold. During the process of plugging and pulling out the terminal, the angle and force cannot be controlled well, which can easily cause the terminal to scrape the tin. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0023] Example

[0024] like Figure 1-3 As shown;

[0025] A power connector terminal sealing mold includes a mold 1, a slider assembly 2 is installed in the mold 1, the slider assembly 2 includes a slider 21, the slider 21 is movably installed in the mold 1, a mounting block 22 is installed on one side of the slider 21, the model and structure of the mounting block 22 are determined by the model of the terminal connector to be processed, and need to match the model of the terminal connector to be processed, the mounting block 22 is provided with two rows of parallel terminal jacks 221, the size of the terminal jacks 221 also depends on the model of the terminal of the terminal connector, a molding cavity 27 is installed on the top of the mounting block 22, the molding cavity 27 is the molding cavity of the insulating seat 25 in the terminal connector, and a fixing seat 28 is used in conjunction with it, the molding cavity 27 and the fixing seat 28 are engaged and fixed, and are sleeved on the periphery of the mounting block 22, and the mold core 23 is covered with a cavity 26, and the mold core 23 is restricted in a fixed position by the cavity 26 The outside of the fixed seat 28 makes the mold core 23 detachable. Two rows of parallel mold core jacks 231 are provided in the mold core 23. Before the terminal connector is manufactured, the corresponding terminal 24 is inserted into the mold core jack 231 on the mold core 23, and then placed in the cavity 26, and then the cavity 26 is installed, and the terminal 24 at the other end is inserted into the terminal jack 221. After the terminal 24 is sealed with glue to form the insulating seat 25, the sliding block 21 separates the terminal 24 at the corresponding end from the terminal jack 221, and then the mold core 23 and the terminal connector are taken out of the cavity 26 as a whole, and then the terminal connector is slowly pulled out of the mold core 23, so that the angle and force of the terminal 24 can be effectively controlled, thereby effectively avoiding the terminal 24 from scraping tin, and at the same time, the mold core 23 and the terminal connector can be taken out as a whole, and the tin scraps can also be easily cleaned;

[0026] Furthermore, the slider assembly 2 is provided with several groups, which can improve the molding cycle and improve the production efficiency. The positions corresponding to the slider assembly 2 in the mold 1 are respectively provided with a cover plate 3 and a limit frame 4. The cover plate 3 limits the positions of the several groups of slider assemblies 2, and the limit frame 4 limits and fixes the cavity 26 to ensure a smooth molding process.

[0027] Furthermore, one side of the plurality of sliders 21 is connected to the same connector 6, and the other side of the connector 6 is provided with a cylinder 5, which is used to drive the sliders 21 to move, thereby increasing the avoidance position and improving the position of the terminal jack 221 when the mounting block 22 moves, thereby effectively preventing the terminal from scraping tin.
