Description

Technical Field

[0001] The present invention relates to the field of injection molding equipment, and particularly to a high-precision injection molding equipment and process for high-speed IO connectors. Background Art

[0002] Some of the existing high-speed IO connectors are designed to be cylindrical. The cylindrical rubber core of the high-speed IO connector is injection-molded to wrap a number of copper pins. Some copper pins are responsible for transmitting signals and carry a relatively small current, so they are relatively thin. Some copper pins are responsible for power supply and need to withstand a large current, so they are made relatively thick.

[0003] For the existing injection molding equipment, the copper pins need to be loaded and injection-molded one by one, and different jigs are required for loading the thick copper pins and the thin copper pins, resulting in relatively low injection molding efficiency.

[0004] Therefore, it is necessary to provide a high-precision injection molding equipment and process for high-speed IO connectors to solve the above technical problems. Summary of the Invention

[0005] To solve the above technical problems, the present invention provides a high-precision injection molding equipment and process for high-speed IO connectors.

[0006] A high-precision injection molding equipment for high-speed IO connectors provided by the present invention includes a base, a fixed mold fixed on the top of the base, and an injection molding machine. The output end of the injection molding machine is communicated with the glue injection port of the fixed mold. Guide rods are fixed at the four corners of the fixed mold. A movable mold is slidably connected to the guide rods together. Springs are sleeved on the guide rods, and the two ends of the springs are respectively connected to the fixed mold and the movable mold. A receiving groove for receiving the springs is provided on the fixed mold. Outer copper pin holes and inner copper pin holes are provided on the movable mold, and the outer copper pin holes and the inner copper pin holes are communicated with the mold cavity of the movable mold. A copper pin conveying device for conveying outer copper pins and inner copper pins is installed on the top of the base.

[0007] The copper needle conveying device includes an inner copper needle vibrating disk and an outer copper needle vibrating disk. The output ends of the inner copper needle vibrating disk and the outer copper needle vibrating disk are respectively fixed with an outer copper needle conveying guide rail and an inner copper needle conveying guide rail. Small connecting sleeves and large connecting sleeves are respectively arranged at the end parts of the outer copper needle conveying guide rail and the inner copper needle conveying guide rail. A stepped rod is rotatably connected within the small connecting sleeve and the large connecting sleeve. A driven gear is fixed in the middle of the stepped rod. An installation plate is fixed on the inner copper needle conveying guide rail. A driving device for driving the stepped rod to rotate is installed on the installation plate. The stepped rod is provided with a thin connecting part rotatably connected to the small connecting sleeve and a thick connecting part rotatably connected to the large connecting sleeve. An outer copper needle receiving groove is arranged on the side wall of the thick connecting part. An inner copper needle receiving groove is arranged on the side wall of the thin connecting part, and the inner copper needle receiving groove extends to the end of the thick connecting part. The copper needle conveying device further includes a pressing device for respectively conveying the outer copper needles in the outer copper needle receiving groove and the inner copper needles in the inner copper needle receiving groove to the outer copper needle holes and the inner copper needle holes.

[0008] Preferably, the pressing device includes a hydraulic rod fixed on the top of the base. The output end of the hydraulic rod is fixed with a U-shaped frame. The end of the U-shaped frame is matched with the moving die. An inner copper needle pressing rod and an outer copper needle pressing rod are fixed inside the U-shaped frame. The servo motor drives the driving gear to rotate. The driving gear drives the driven gear and the stepped rod to rotate synchronously. Under the action of gravity, the inner copper needles and the outer copper needles respectively enter the corresponding tracks along the inner copper needle conveying guide rail and the outer copper needle conveying guide rail first, and then enter the inner copper needle receiving groove and the outer copper needle receiving groove respectively. As the stepped rod rotates, all the inner copper needle receiving grooves are filled with one inner copper needle, and all the outer copper needle receiving grooves are filled with one outer copper needle.

[0009] The hydraulic rod is pushed to move the U-shaped frame forward, driving the inner copper needle pressing rod and the outer copper needle pressing rod to act synchronously.

[0010] The end parts of the inner copper needle pressing rod and the outer copper needle pressing rod are designed to be flush to ensure that the inner and outer copper needles are stressed simultaneously, and the inner copper needles and the outer copper needles in the inner copper needle receiving groove and the outer copper needle receiving groove are pushed into the corresponding inner copper needle holes and outer copper needle holes of the moving die.

[0011] While the U-shaped frame pushes the inner copper needles and the outer copper needles, it contacts the moving die and pushes it to slide along the guide rod towards the fixed die to realize mold closing. During this process, the spring is compressed until the spring is completely compressed into the receiving groove.

[0012] After the mold is closed, injection molding is performed through an injection molding machine, so that the inner copper needle and the outer copper needle are wrapped by the injection liquid. After cooling, the hydraulic rod drives the U-shaped frame to move backward, and the fixed mold and the movable mold are separated under the elastic force of the spring. The inner copper needle extrusion rod and the outer copper needle extrusion rod are moved out of the inner copper needle accommodating groove and the outer copper needle accommodating groove and reset, and the above operation is repeated.

[0013] Preferably, the ends of the inner copper needle extrusion rod and the outer copper needle extrusion rod are flush.

[0014] Preferably, the hydraulic rod is directly opposite to the center of the U-shaped frame, so that the force on the U-shaped frame is more uniform.

[0015] Preferably, the hydraulic rod and the step rod are in the same straight line, so that the U-shaped frame is more evenly stressed.

[0016] Preferably, the driving device comprises a servo motor fixed on a mounting plate, a driving gear is fixed to an output end of the servo motor, and the driving gear is meshingly connected with a driven gear.

[0017] Preferably, the entrances of the outer copper needle hole and the inner copper needle hole are provided with chamfers to facilitate the outer copper needle and the inner copper needle to enter the outer copper needle hole and the inner copper needle hole.

[0018] Preferably, the small connecting sleeve and the large connecting sleeve both include an arc-shaped plate sleeved on the step rod and a track arranged on the side wall of the arc-shaped plate.

[0019] Preferably, a telescopic rod is installed between the base and the U-shaped frame to make the U-shaped frame move more smoothly.

[0021] Compared with the related technology, the present invention has the following beneficial effects: High precision and automation: The equipment sorts the copper needles through the vibrating disk to ensure that the copper needles are neatly arranged in a preset direction, improving the accuracy and efficiency of copper needle insertion.

[0022] The design of the stepped rod cooperates with the drive of the servo motor to achieve the automatic positioning and conveying of the copper pins, reducing manual intervention and improving the level of production automation.

[0023] The hydraulic rod drives the U-shaped frame to move forward, ensuring that the inner copper pins and the outer copper pins are stressed simultaneously and accurately pushed into the corresponding holes of the moving mold, guaranteeing the high precision of injection molding.

[0024] Efficient production: The equipment adopts the design of continuous feeding and automatic station switching, enabling the vibrating bowl, guide rail, stepped rod and injection molding machine to work together to form a continuous production process, significantly improving production efficiency.
