Description

Ejection structure of a crimping die

Technical Field

The utility model relates to the technical field of crimping dies, in particular to an ejection structure of a crimping dies.

Background Art

A crimping die is a tool used in the crimping process to connect or form two or more wire harnesses by applying pressure. It is widely used in automobile manufacturing, electronic equipment, and home appliances. There are many electrical systems in a car, and the electrical system consists of multiple wire harnesses. A crimping die is needed to crimp the wire harnesses together, which can ensure the stability of the car's wire harness connection and save car space.

Most traditional crimping dies have a crimping groove on the top. When in use, first put the wire harness and terminal in, then drive the electronic device to move the crimping head matching the crimping groove into the middle of the crimping groove, so that the wire harness and the terminal can be crimped. However, when crimping the wire harness and the terminal, the entry of the crimping head will squeeze the terminal at the bottom and around the crimping groove. After long-term use, the crimping groove on the die needs to be cleaned or the die needs to be replaced. Most of the die is connected to the base on which the die is placed by bolts. This method requires employees to use matching tools to install or disassemble the die, which is inconvenient and increases the labor intensity of employees. Therefore, a crimping die ejection structure is proposed to solve the above problems.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

1-4, an embodiment of the utility model is provided: an ejection structure of a crimping mold, comprising a base 1, a mounting base 2 is fixedly connected to the top of the base 1, a mold body 3 is slidably connected to the middle of the mounting base 2, a card slot 4 is provided on the outer side of the mold body 3, a push rod 17 is slidably connected to the middle of the mounting base 2, a movable plate 18 is fixedly connected to one end of the push rod 17, a connecting plate 5 is rotatably connected to the other side of the movable plate 18, a clamping block 6 is rotatably connected to the other side of the connecting plate 5, the clamping block 6 is slidably connected to the middle of the clamping slot 4, a spring 7 is fixedly connected to the side of the clamping block 6 away from the clamping slot 4, pressing the push rod 17 can drive the movable plate 18 to move, and then the clamping block 6 is pulled under the action of the connecting plate 5, so that the clamping block 6 is away from the middle of the clamping slot 4, and the mold body 3 can be conveniently pressed. For disassembly, by inserting the mold body 3 into the middle of the mounting seat 2, the block 6 can be squeezed to make the block 6 away from the mold body 3, and the spring 7 can be compressed at the same time. When the slot 4 moves to the original position of the block 6, the block 6 can be bounced into the middle of the slot 4 under the action of the spring 7, so that the mold body 3 can be conveniently installed. No tools are required when installing and disassembling the mold body 3, and the labor intensity of employees is reduced. The top of the base 1 is fixedly connected to the frame 13, and the top of the frame 13 is fixedly connected to the electric telescopic rod 14. The output end of the electric telescopic rod 14 is fixedly connected to the crimping head 15. By driving the electric telescopic rod 14, the crimping head 15 can be driven to move, so that the wiring harness and the terminal can be crimped to make it a finished product.

The inside of the base 1 is fixedly connected with a hydraulic cylinder 9, which is slidably connected to the base 1, the mounting seat 2 and the middle part of the mold body 3. The inner bottom of the mold body 3 is fixedly connected with a tension spring 10, and the other end of the tension spring 10 is fixedly connected with a push plate 11, which is slidably connected to the middle part of the mold body 3. The inner bottom of the mold body 3 is fixedly connected with a fixing rod 12, and the fixing rod 12 is in contact with the push plate 11. The push plate 11 can be driven to move by driving the hydraulic cylinder 9. At the same time, in order to prevent the mold body 3 from being unable to be disassembled, the hydraulic cylinder 9 directly lifts the bottom of the push plate 11, and the finished product inside the mold body 3 can be pushed out of the middle part of the mold body 3. At the same time, under the action of the tension spring 10, the push plate 11 can be pulled back to its original position, which can avoid the terminal being squeezed in the middle part of the mold body 3 and the need for employees to clean it, thereby improving the efficiency of crimping the wire harness and reducing the labor intensity of employees.

Through holes are provided in the middle of the base 1, the mounting seat 2 and the mold body 3. The output end of the hydraulic cylinder 9 is slidably connected to the middle of the through hole to limit the moving position of the hydraulic cylinder 9. The hydraulic cylinder 9 can lift the bottom center point of the push plate 11 so that the objects above can slide vertically out of the mold body 3.

A cushion block 16 is fixedly connected to the bottom of the base 1. The cushion block 16 can prevent the device from shaking during operation and causing the surface of the device to contact and rub against the ground.

The upper and lower sides of the movable plate 18 are fixedly connected to the limiting blocks, and the upper and lower sides of the interior of the mounting seat 2 are provided with limiting grooves. The limiting blocks are slidably connected to the middle of the limiting grooves.

The side of the connecting plate 5 away from the movable plate 18 is specifically fixedly connected to the front side of the stopper 8. Under the action of the stopper 8, the connecting plate 5 can be limited to prevent the spring 7 from popping the block 6 out of the middle of the mounting seat 2.

The top of the clamping block 6 is set to be an arc, and the bottom of the mold body 3 is in contact with the arc. The arc can fix the mold body 3 in the middle of the mounting seat 2 without pressing the push rod 17 when installing the mold body 3.

Working principle: When in use, place the wire harness and terminal in the middle of the mold body 3, drive the electric telescopic rod 14 to drive the crimping head 15 to move, and then crimp the wire harness and terminal to make it a finished product. When the crimping work is completed, drive the hydraulic cylinder 9 to drive the push plate 11 to move, and the finished product inside the mold body 3 can be pushed out of the middle of the mold body 3. At the same time, the push plate 11 can be pulled back to its original position under the action of the tension spring 10, which can avoid the terminal being squeezed in the middle of the mold body 3, and the need for employees to clean up improves the efficiency of crimping the wire harness and reduces the labor intensity of employees. By pressing the push rod 17, the movable plate 18 can be driven to move, and then the block 6 is pulled under the action of the connecting plate 5, so that the block 6 is away from the middle of the slot 4, and the mold body 3 can be easily disassembled. By inserting the mold body 3 into the middle of the mounting seat 2, the block 6 can be squeezed to make the block 6 away from the mold body 3, and the spring 7 is compressed at the same time. When the slot 4 moves to the original position of the block 6, the block 6 can be bounced into the middle of the slot 4 under the action of the spring 7, and then the mold body 3 can be easily installed. No tools are required when installing and disassembling the mold body 3, and the labor intensity of employees is reduced.
