Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, specifically to a mold for manufacturing metal terminals of vehicle connectors with a demolding unit. Background Technology

[0002] Automotive connectors are key components of vehicle electronic systems, responsible for the efficient transmission of power, signals, and data, ensuring stable interconnection of onboard devices (such as ECUs, sensors, and displays). Their functions include waterproof and shockproof design to ensure reliability, and modular interfaces to simplify the overall vehicle wiring harness layout, improving the level of automotive intelligence and electrification. Within the internal structure of automotive connectors, metal terminals are crucial components, used to clamp the wire cores and achieve electrical connection with the target electrical socket.

[0003] Existing automotive connector metal terminal manufacturing molds with demolding units are inconvenient to install top mold components in the mold groove to eject the product due to the small size of the mold groove structure and the produced metal terminals. They also lack reliable product demolding methods and reliable collection functions for small metal terminals. Therefore, we propose an automotive connector metal terminal manufacturing mold with demolding units. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a mold for manufacturing metal terminals of automotive connectors with a demolding unit. This mold features a reliable molding and demolding unit. Under the action of bearings and end shafts, the mold groove frame can rotate. When the mold groove port faces downwards, a vibration generator activates, generating vibrations by striking the mold groove frame, causing the metal terminals to fall out of the mold groove, thus achieving a convenient and effective demolding effect. Furthermore, it has a reliable product collection unit. The metal terminals falling from the mold groove frame are distributed to the front and rear sides as they pass through the guide frame and continue falling into the collection box. When the collection box is full, it can be removed via a pull ring for easy emptying or replacement. In addition, this mold allows for easy splicing of the base and addition of molds, thus supporting the expansion of production scale and effectively solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold for manufacturing metal terminals of vehicle connectors with a demolding unit, comprising a splicing base, a molding demolding unit, and a product collection unit;

[0006] The splicing base is set vertically, and its vertical cross-section is U-shaped. The upper ends of its left and right sides are L-shaped. There are no fewer than three mold groove rods arranged in parallel above the splicing base.

[0007] Molding and demolding unit: includes mold grooves, hydraulic cylinders, upper mold cover, side support pillars, bearings, and vibration generators. Each mold groove rod has a row of rectangular mold grooves arranged in a horizontal linear array at its upper end. A molding module is set inside the mold groove. A set of hydraulic cylinders and an upper mold cover are installed above each mold groove. The upper mold cover is installed on the lower side of the hydraulic cylinder. A vertical side support pillar is installed at both ends of each mold groove rod. A bearing is embedded at the upper position of the opposite side of each of the two side support pillars. A short shaft is fixedly connected to the center position of each end of the mold groove rod. The two short shafts are inserted into and fixed to the inner ring side of the bearing. A vibration generator is fixedly installed at the lower end of the mold groove rod and at the vertical position corresponding to each mold groove.

[0008] Product collection unit: installed inside the splicing base and at both the front and rear ends.

[0009] The mold groove is used to hold liquid metal, and under the action of the internal molding module and the upper mold cover, the metal terminal is shaped and produced. The hydraulic cylinder is used to push the upper mold cover down into the mold groove, which can play a role in covering and preventing dust while participating in the molding. Under the action of the bearing and the end shaft, the mold groove rod can be rotated. When it is rotated to the point where the mold groove port is facing down, the vibration generator starts to work. By striking the mold groove rod, vibration is generated, which can make the metal terminal fall out of the mold groove, thereby achieving a convenient and effective demolding effect.

[0010] Furthermore, the molding and demolding unit also includes a motor, a motor support plate, and retaining rings. A motor support plate is fixedly connected to the upper outer end of each left-side side support column. The motor is mounted on the upper end of the motor support plate. The retaining rings are secured to the outside of the motor, and both ends are fixedly connected to the motor support plate with bolts. The output shaft of the motor faces inward and is also fixedly connected to the inner ring side of the bearing. After the metal terminal is shaped, the upper mold cover is retracted upward, and then the motor starts working, driving the mold groove frame to rotate. The motor support plate supports the motor, and the retaining rings fix the motor in place.

[0011] Furthermore, the molding and demolding unit also includes a raw material box, an upper mounting frame and a feed port, a telescopic steel pipe and a solenoid valve. Each set of side support columns has a vertical upper mounting frame installed at its upper end. The hydraulic cylinder is fixedly mounted on the upper end of the upper mounting frame, and a raw material box is installed on the upper end of the upper mounting frame. The raw material box has a clearance channel with the same number of hydraulic cylinders inside. The cylinder body of the hydraulic cylinder passes through the clearance channel. Each upper mold cover has two solenoid valves installed inside. The upper end of the solenoid valve is connected to the inside of the raw material box through a telescopic steel pipe. The valve block of the lower discharge port of the solenoid valve is flush with the lower end of the upper mold cover. A feed port is fixedly connected to both the left and right ends of the raw material box. The feed port passes through the end of the upper mounting frame and extends horizontally outward. The upper mounting bracket is used for the installation of the raw material box and hydraulic cylinder. The clearance channel inside the raw material box is used to make room for the installation of the hydraulic cylinder. The solenoid valve is used to control the injection and stop of liquid metal raw materials. The telescopic steel pipe is used to transport raw materials to the solenoid valve, and its length can be changed by telescopic movement with the movement of the upper mold cover. The valve block of the lower outlet of the solenoid valve is flush with the lower end of the upper mold cover, which can prevent the upper end of the product from having a protrusion. The feed pipe is used to install pipes to connect to external material sources.

[0012] Furthermore, the product collection unit includes slots, inserts, and mounting crossbars. The front end of the splicing base has two slots, one on the left and one on the right. An insert is fixedly connected to the rear end of the splicing base at a position corresponding longitudinally to the slots. The mounting crossbar is fixedly connected to the lower side of the side support, and both ends of the mounting crossbar are bolted to the inner corners of the L-shaped upper end of the splicing base. Multiple splicing bases can be effectively spliced ​​together through the insert and slot structure at the ends, thereby supporting the expansion of production scale. The mounting crossbar is fixed to the splicing base with bolts, allowing for the addition of molds as needed.

[0013] Furthermore, the product collection unit also includes a container, a pull ring, and a flow guide. A flow guide with a triangular cross-section is fixedly connected to the upper end of each mounting crossbar. At least four container boxes are inserted inside the splicing base. Each container box has a rectangular structure and is slidably connected to the right end of the splicing base. A pull ring is fixedly connected to the right end of each container box. Metal terminal products falling from the mold slot frame are distributed to the front and rear sides as they pass through the flow guide and continue falling into the container boxes. When the container box is full, it can be removed using the pull ring for easy emptying or replacement.

[0014] Furthermore, the molding module inside the mold groove includes a central square block, two right-angled trapezoidal blocks, two arc-shaped grooves, and a small cylindrical block. Two arc-shaped protrusions are fixedly connected to the lower corner of the upper mold cover, with the two arc-shaped protrusions and two arc-shaped grooves vertically corresponding to each other. The central square block is used to mold the central locking hole of the metal terminal, serving as a limiting and locking mechanism against the connector housing during installation. The two right-angled trapezoidal blocks are used to clamp and mold the plug portion of the metal terminal. The two arc-shaped grooves, in conjunction with the arc-shaped protrusions on the lower side of the upper mold cover, can mold the wire clamp at the tail of the terminal. The small cylindrical block is used to mold and produce the locking hole for the plug portion.

[0036] The working principle of the vehicle connector metal terminal manufacturing mold with a demolding unit provided by this utility model is as follows: This mold is equipped with a reliable molding and demolding unit 3: the mold groove 31 is used to hold liquid metal, and under the action of the internal molding module and the upper mold cover 33, the metal terminal is shaped and produced. The hydraulic cylinder 32 is used to push the upper mold cover 33 down into the mold groove 31, which can play a role in covering and preventing dust while participating in the molding. Inside the mold groove, the central square block is used to shape the central locking hole of the metal terminal, which is used to limit and lock the connector shell during installation.

After the metal terminal is shaped, the upper mold cover 33 is retracted upward. Then, the motor 37 starts working, driving the mold groove rod 2 to flip. When the mold groove 31 port faces downward, the vibration generator 310 starts working, generating vibration by striking the mold groove rod 2, which can cause the metal terminal to fall out of the mold groove 31, thereby achieving a convenient and effective demolding effect. The motor support plate 38 is used to support the motor 37, and the retaining ring 39 is used to fix the motor 37. The upper mounting bracket 311 is used to install the raw material box 34 and the hydraulic cylinder 32.

The solenoid valve 314 is used to control the injection and stop of liquid metal raw materials. The telescopic steel pipe 313 is used to transport raw materials to the solenoid valve 314, and its length can be changed by telescopic movement with the movement of the upper mold cover 33. The valve block of the lower outlet of the solenoid valve 314 is flush with the lower end of the upper mold cover 33, which can prevent the upper end of the product from having a protrusion. The feed pipe 312 is used to install a pipe to connect to the external material source. This mold also features a reliable product collection unit 4. Metal terminal products falling from the mold groove frame 2 are distributed to the front and rear sides as they pass through the guide frame 46, and continue to fall into the container 43. When the container 43 is full, it can be removed by the pull ring 44 for easy emptying or replacement. Furthermore, this mold allows for easy splicing of the base and addition of molds, thus supporting production scale expansion: multiple splicing bases 1 can be effectively spliced ​​through the end insert slot structure, thereby supporting production scale expansion. The mounting crossbar 45 is fixed to the splicing base 1 with bolts, allowing the number of molds to be added as needed.
