[0002] Automotive connectors, as key components in automotive electronic systems, play a vital role in connectivity and transmission. They are the core components for achieving electrical connections between wiring harnesses and between wiring harnesses and electrical devices, ensuring the efficient and stable operation of the complex electronic networks within the vehicle. These connectors typically consist of a plastic housing, metal terminals, and a locking mechanism. Their precision design is engineered to withstand harsh environmental factors such as vibration, moisture, and temperature fluctuations. They not only simplify the wiring harness assembly process and improve production efficiency, but also facilitate subsequent maintenance and replacement. Connectors are widely used in automotive manufacturing, ensuring reliable connections for everything from engine management systems and lighting to infotainment systems. Therefore, the quality and performance of automotive connectors directly impact the overall safety and reliability of the vehicle, making them an integral part of the modern automotive industry.

[0003] For example, the authorization announcement number, CN212861324U, discloses a connector for automobiles, including a sub-connector structure, a vehicle body sheet metal, a sealing mechanism and a mother connector structure. The first wire port, the connecting hole, the through hole and the second wire port can better constrain the wiring harness to prevent interference between the wiring harness and other components, reduce damage to the wiring harness, and improve the reliability of the automobile circuit. The device can be quickly positioned by setting the first guide block, the guide groove and the second guide block, which increases the accuracy and efficiency of the installation. The sub-connector body and the mother connector body can be quickly disassembled and installed through the cooperation between the card plate, the fixed slide frame, the slider, the locking nut, the card block and the card slot, which facilitates the maintenance and inspection of the wiring harness, improves work efficiency and increases the practicality of the device. The sealing mechanism is an extrusion sealing structure, which improves the sealing between the sub-connector and the mother connector and increases the waterproof and noise-proof effect.

[0004] Since automotive connectors are usually composed of sub-connectors and mother connectors, existing automotive connector molds can usually only perform single injection molding of sub-connectors or mother connectors, and cannot perform injection molding of sub-connectors and mother connectors at the same time, which affects the production efficiency of automotive connectors; therefore, the market urgently needs to develop an automotive connector mold structure to help people solve the existing problems.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4 The utility model provides an embodiment of an automobile connector mold structure, comprising a lower mold 1 and an upper mold 5. A female connector mold groove 101 and a sub-connector mold groove 102 are respectively provided on both sides of the middle portion of the upper end surface of the lower mold 1. The upper end of the lower mold 1 is connected to the upper mold 5. A female connector mold core 501 and a sub-connector mold core 502 are respectively fixedly connected on both sides of the middle portion of the lower end surface of the upper mold 5. Positioning rods 104 are fixedly connected to the front and rear ends of both sides of the upper end surface of the lower mold 1. Guide holes 503 are provided on both sides of the front and rear ends of both sides of the lower end surface of the upper mold 5. The upper ends of the four positioning rods 104 on the upper end surface of the lower mold 1 are respectively inserted into the four guide holes 503 on the lower end surface of the upper mold 5. The lower mold 1 and the upper mold 5 are positioned and connected by four positioning rods 104, so that the lower mold 1 and the upper mold 5 remain vertically aligned, and the lower mold 1 is driven down by an external lifting mechanism. When the lower mold 1 descends, it is guided by the positioning rods 104 to slide along the guide holes 503, so that the upper mold 5 remains stable when it is lifted and lowered. After the upper mold 5 descends, the female connector mold core 501 and the sub-connector mold core 502 are respectively inserted into the female connector mold groove 101 and the sub-connector mold groove 102 on the lower mold 1, and injection molding is performed simultaneously into the female connector mold groove 101 and the sub-connector mold groove 102, so as to realize the simultaneous injection molding of the sub-connector and the female connector, thereby improving the production efficiency of automobile connectors.

[0024] See also Figure 2-4, the inside of the female connector mold groove 101 and the sub-connector mold groove 102 are respectively provided with a stripping plate 3 that matches the shape of the female connector mold groove 101 and the sub-connector mold groove 102, and the front and rear ends of both sides of the female connector mold groove 101 and the sub-connector mold groove 102 are connected with a rectangular movable groove 103, and the front and rear ends of both sides of the two stripping plates 3 are fixedly connected with a rectangular lifting column 4, which is inserted into the rectangular movable groove 103. The upper end of the rectangular movable groove 103 extends out of the upper end surface of the lower mold 1, and a circular telescopic groove 401 is provided inside the rectangular lifting column 4. A through hole 402 is provided between the lower end of the circular telescopic groove 401 and the lower end surface of the rectangular lifting column 4. The lower end of the rectangular movable groove 103 is fixedly connected with a fixing rod 2, and the upper end of the fixing rod 2 extends through the through hole 402 to the inside of the circular telescopic groove 401 and is fixedly connected with a circular guide column 201. A spring 403 is provided at the upper end of the circular guide column 201. When the lower mold 1 descends, it will first press down the upper ends of multiple rectangular lifting columns 4 at the same time, so that the rectangular lifting columns 4 descend and retract into the rectangular movable groove 103. When the rectangular lifting columns 4 descend, they will simultaneously drive the stripping plate 3 to descend, so that the two stripping plates 3 are respectively fitted with the lower end surfaces of the female connector mold core 501 and the sub-connector mold core 502 after they descend. When the rectangular lifting columns 4 descend, the fixed rod 2 remains stationary, thereby causing the circular guide column 201 to rise inside the circular telescopic groove 401 and compress the spring 403. When the sub-connector and the female connector are injection molded and cooled, the upper mold 5 is lifted, and the restoring force of the spring 403 pushes the rectangular lifting columns 4 to rise, thereby causing the rectangular lifting columns 4 to drive the stripping plate 3, so that the stripping plate 3 pushes the injected sub-connector and the female connector to rise for demoulding, thereby improving the demoulding efficiency of the sub-connector and the female connector.

[0025] Working Principle: During use, the lower mold 1 and upper mold 5 are first aligned vertically via the four positioning rods 104 and the guide holes 503. Subsequently, the lower mold 1 is lowered by an external lifting mechanism. As the lower mold 1 descends, the positioning rods 104 slide along the guide holes 503 to provide guidance, ensuring the stability of the upper mold 5 during its ascent and descent. Once the upper mold 5 is lowered into position, the female connector core 501 and the sub-connector core 502 are precisely inserted into the female connector cavity 101 and sub-connector cavity 102, respectively, on the lower mold 1. At this point, the lower mold 1 simultaneously presses down on the upper ends of multiple rectangular lifting columns 4, causing them to descend and driving the stripper plate 3 downward. Once the stripper plate 3 descends, it engages the lower end surfaces of the female connector core 501 and sub-connector core 502. Meanwhile, the fixed rod 2 remains stationary, while the circular guide column 201 rises within the circular expansion slot 401, compressing the spring 403. Next, injection molding is performed into the female connector cavity 101 and the female connector cavity 102, achieving simultaneous injection molding of the female and male connectors, thereby improving production efficiency. After the injection molding is completed and cooled, the upper mold 5 is raised. At this time, the restoring force of the spring 403 pushes the rectangular lifting column 4 upward, thereby driving the stripper plate 3 upward. The stripper plate 3 pushes the completed female and male connectors upward for demolding, effectively improving the demolding efficiency of the female and male connectors.
