Description

Technical Field

[0001] The utility model belongs to the technical field of molds for offline crimping machines, and in particular relates to a mold replacement structure for offline crimping machines. Background Art

[0002] The offline crimping machine is an automated device dedicated to wire processing. It can automatically complete the cutting, stripping and crimping of wire ends and terminals (connectors). It is widely used in automotive wiring harnesses, electrical appliance manufacturing and other fields. This process improves production efficiency and ensures the quality and consistency of the contacts. The die replacement structure of the offline crimping machine refers to the part used to fix and replace crimping dies of different sizes or types to adapt to different cable and terminal specifications. Traditional die replacement structures often rely on bolts for fixing.

[0003] The existing die replacement structure of the offline crimping machine is fixed with bolts. When replacing, multiple bolts need to be manually loosened and tightened, which is not only time-consuming and labor-intensive, but also requires professional tools and certain skills to ensure the correct tightening of the bolts to avoid loosening or damage of the die due to improper torque. It may also cause accidents due to improper use of tools or improper fastening of bolts. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a mold replacement structure for an offline crimping machine, which can complete the mold replacement in a very short time, reduce production interruption time, improve overall production efficiency, and reduce the requirements on operator skills.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a mold replacement structure of an offline crimping machine, including a frame plate, an electric push rod is arranged on the upper end of the frame plate, a mounting slot plate is arranged on the telescopic end of the electric push rod, an upper mold seat is slidingly arranged inside the mounting slot plate, a connecting plate is arranged inside the frame plate, a lower mold seat corresponding to the upper and lower positions of the upper mold seat is placed on the upper end of the connecting plate, a locking limit mechanism 1 for locking the upper mold seat is arranged on the upper end of the mounting slot plate, a locking limit mechanism 2 for locking the lower mold seat is arranged inside the connecting plate, the locking limit mechanism 1 includes a rectangular plate arranged on the upper end of the mounting slot plate, two sliding columns are slidingly arranged inside the rectangular plate, a sealing plate located on the front side of the upper mold seat is arranged between the lower ends of the two sliding columns, and the two A pulling plate is arranged between the other ends of the sliding columns, and an elastic driving component is arranged between the sealing plate and the rectangular plate. The elastic driving component includes two springs arranged between the sealing plate and the rectangular plate, and the two springs are respectively sleeved on the corresponding outer arc surfaces of the sliding columns. The second locking limit mechanism includes two locking plates slidably arranged inside the connecting plate, and locking grooves are respectively provided on the left and right sides of the lower mold base. The two locking plates are respectively plugged into adjacent locking grooves. A bidirectional screw is arranged for internal rotation of the connecting plate, and the two locking plates are respectively threadedly connected to the left and right corresponding ends of the bidirectional screw. An electric driving unit for driving the bidirectional screw to rotate is arranged on the left side of the connecting plate, and the electric driving unit includes a motor arranged on the left side of the connecting plate, and the output shaft of the motor is connected to the left end of the bidirectional screw through a coupling.

[0006] As a further improvement of the present invention, a control panel is arranged inside the frame plate, and the motor and the electric push rod are electrically connected to the control panel.

[0007] As a further improvement of the present invention, a plurality of mounting plates are respectively arranged on the left and right sides of the lower end of the frame plate, and mounting holes are opened inside the plurality of mounting plates.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, by placing the stripped wires and terminals on the lower die base, and then controlling the control panel to open the electric push rod to move the upper die base on the mounting slot plate downward, mechanical pressure is used to make the terminals tightly wrap the wires to form a reliable electrical connection.

[0010] Secondly, by pulling the pull plate, the sealing plate on the sliding column leaves the front side of the mounting groove plate, thereby unlocking the upper die seat. At this time, the spring is in a compressed state, and the upper die seat can be slid out, and the upper die seat to be replaced can be slid into the interior of the mounting groove plate. Then the pull plate is released, and the spring quickly rebounds and drives the sealing plate to move downward to the front side of the mounting groove plate, thereby realizing the limited installation of the upper die seat. When the lower die seat needs to be replaced, the motor is turned on through the control panel, and the output shaft drives the bidirectional screw to rotate, so that the locking plates on both sides can move away from the locking groove opened on the lower die seat. Then the lower die seat is taken out, and the lower die seat to be replaced is placed on the connecting plate. Then the motor is turned on through the control panel, so that the bidirectional screw rotates and drives the locking plates on both sides to move closer to each other and insert into the locking groove opened on the lower die seat, thereby realizing the rapid replacement of the lower die seat. The mold can be replaced in a very short time, reducing production interruption time, improving overall production efficiency, and reducing the skill requirements for operators.

[0011] Third, the replacement structure can be quickly installed to a suitable position through the mounting holes on the mounting plate, making it easy for personnel to install.

[0012] Fourthly, the control panel can be used to facilitate personnel to control the electrical components on the replacement structure. BRIEF DESCRIPTION OF THE DRAWINGS
