[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automotive wiring harness terminal crimping mold, comprising a base, the base being placed on the ground to provide support for the whole, a U-shaped plate being fixedly connected to the upper surface of the base, a cylinder being fixedly connected to the top of the U-shaped plate, a movable plate being fixedly connected to the output end of the cylinder, a bottom plate being installed on the top of the base, wherein a pressing groove is formed on the upper surface of the bottom plate, a pressing block being detachably installed on the movable plate with the aid of an auxiliary device, and an adjustment device being provided on the movable plate, wherein the adjustment device can rotate the pressing block.

[0006] The aforementioned components achieve the following effect: When automotive wiring harnesses need to be processed, the operator moves the wiring harness and places it in the pressure groove of the base plate. Then, the cylinder on the U-shaped plate is opened, and the cylinder moves the moving plate and pressure block. Finally, the pressure block squeezes the automotive wiring harness on the base plate, achieving the effect of crimping the automotive wiring harness. When it is necessary to crimp automotive wiring harnesses of different shapes, the operator rotates the pressure block through the adjustment device, moving the pressure block corresponding to the shape of the automotive wiring harness to the bottom of the moving plate, thus improving the efficiency of automotive wiring harness processing.

[0007] Preferably, the adjusting device includes a rotating rod rotatably connected to both ends of a movable plate. One end of the rotating rod has a groove, and a guide rod is slidably connected to the rotating rod via the groove. One end of the guide rod is fixedly connected to a pad, and four insert rods are fixedly connected to one side of the pad. The movable plate has insertion holes corresponding to the insertion rods, wherein the size of the insertion rods matches the size of the insertion holes.

[0013] Preferably, the arc surface of the guide rod is fixedly connected to a sliding plate, and the rotating rod is provided with a sliding groove corresponding to the sliding plate, wherein the sliding plate and the sliding groove are slidably adapted to each other.

[0014] The effect achieved by the above components is that the sliding plate of the guide rod moves in the groove of the rotating rod, thereby restricting the movement direction of the guide rod and the rotating rod and preventing rotation between the guide rod and the rotating rod.

[0015] Preferably, the auxiliary device includes four mounting slots, which are respectively opened around the fixed block. The pressure block is fixedly connected to the mounting slot with a mounting plate, wherein the size of the mounting plate is adapted to the size of the mounting slot. The threaded hole is opened on the surface of the mounting plate, and the mounting plate is threaded with a bolt at the threaded hole, wherein the size of the bolt is adapted to the size of the threaded hole.

[0016] The effect achieved by the above components is as follows: when the pressure block needs to be installed, the worker moves the pressure block, the mounting plate of the pressure block is inserted into the mounting groove of the fixing block, and then the worker rotates the bolt, the bolt passes through the fixing block and is inserted into the threaded hole of the mounting plate, thus achieving the effect of fixing the mounting plate and the pressure block. The auxiliary device achieves the effect of installing the pressure block, making it convenient for the worker to replace the pressure block when it is damaged.

[0017] Preferably, one end of the bolt is fixedly connected to a pull rope, wherein one end of the pull rope is fixedly connected to the fixing block.

[0018] The effect achieved by the above components is that by setting up a pull rope, the maximum displacement of the bolt is limited, thus preventing the bolt from falling off when not in use.

[0019] Preferably, one end of the mounting plate has two ramps, and the two ramps are centrally symmetrical.

[0020] The effect achieved by the above components is that the ramp facilitates the guidance of the mounting plate into the mounting slot of the fixing block, bringing convenience to the staff.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When crimping automotive wiring harnesses of different sizes and shapes, the operator pulls the pad, which slides along with the guide rod in the groove of the rotating rod. The spring deforms, and the insertion rod on the pad moves away from the insertion hole of the moving plate. The operator then rotates the pad, causing the guide rod and rotating rod to rotate as well. The fixing block and pressure block on the rotating rod also rotate. When the pressure block corresponding to the automotive wiring harness moves to the appropriate position, the operator releases the pad. Under the spring's restoring force, the insertion rod on the pad inserts into the insertion hole of the moving plate, thus fixing the guide rod. The adjustment device allows for rotation of the pressure block, facilitating the selection of pressure blocks when crimping automotive wiring harnesses of different shapes and improving the processing efficiency of automotive wiring harnesses.
