The upper molding die surface 440 and the lower molding die surface 340 are opposite to each other in vertical direction. The upper blade portion 431 and the lower blade portion 331 are opposite to each other in vertical direction. The mold opening and closing driver 500 is arranged on the machine base 100 and is used to drive the upper mold 400 to move up and down so that the upper mold 400 and the lower mold 300 can be molded and opened.

[0040] When forming the pins of electronic components, the electronic components are placed in the workpiece placement position 321 of the lower main mold 320, so that the pins of the electronic components extend to a position relative to the upper and lower molding mold surfaces and the upper and lower blades. The mold opening and closing driver 500 drives the upper mold 400 and the lower mold 300 to close the molds, and the upper and lower blades are cut to cut off excess pins. At the same time, the upper and lower molding mold surfaces 340 are closed to stamp the pins. Finally, the mold opening and closing driver 500 drives the upper mold 400 to move upward to open the mold, thereby completing the pin forming work of the electronic components.

[0041] In the above-mentioned pin forming machine, the upper mold 300 and the lower mold 300 form a module that can be disassembled independently, so as to facilitate the overall disassembly, and the lower mold 300 and the upper mold 400 are decomposed into components such as a mold base, a main mold and a knife mold to form a molding surface and a blade part. The mold base, the main mold and the knife mold can all be disassembled, so as to facilitate the replacement or free combination of the components of the mold according to actual conditions to form molds with different molding cavities and different cutting positions and cutting structures. The production and manufacturing are convenient and flexible. In addition, it is also convenient to partially replace the components of the mold for maintenance to avoid overall replacement. The maintenance is convenient and flexible.

[0042] In the embodiment, the mold opening and closing driver 500 can be specifically a cylinder, a hydraulic cylinder or an electromagnet, etc., and can be specifically configured according to actual conditions. In the embodiment, the mold opening and closing driver 500 can be fixed to the machine base 100, and the action part of the mold opening and closing driver 500 is fixed to the upper mold mounting base 200, so as to drive the upper mold 400 to move up and down.

[0043] In the embodiment, the upper die mounting seat 200 can be slidably disposed on the lower die mounting seat 110 through a guide rod structure, so that the upper die mounting seat 200 can move up and down relative to the lower die mounting seat 110. Of course, it is conceivable that the upper die mounting seat 200 can also be movably disposed on other parts of the machine base 100 through other structural connections, such as through a linear guide assembly.

[0044] In an embodiment, the detachable connection between the components may be specifically realized by threaded fasteners, or by other detachable connection structures, such as a snap connection and a pin connection, and a combination thereof, and the like.

[0045] In the embodiment, the lower cutting dies 330 are arranged in pairs on the left and right sides of the workpiece placement position 321, and form two lower molding die surfaces 340 with the left and right sides of the lower main die 320 respectively; the upper main die 420 is provided with two upper molding die surfaces 440 corresponding to the two lower molding die surfaces 340 one by one; the upper cutting dies 430 are arranged in pairs on the left and right sides of the upper main die 420, and the two upper blade portions 431 of the two upper cutting dies 430 correspond to the two lower blade portions 331 of the two lower cutting dies 330 one by one. With the above structure, electronic components with pins on both sides can be cut and molded simultaneously, with high efficiency. Of course, in some embodiments, if the electronic component has pins on only one side, only a single lower cutting die 330 and an upper cutting die 430 can be provided, and only one side of the molding die surface can be provided.

[0046] In the embodiment, the lower main mold 320 can be movably arranged on the lower mold base 310 up and down, and the lower mold 300 also includes a first elastic member 350, which is arranged between the lower mold base 310 and the lower main mold 320 and is used to reset the lower main mold 320 upward. With the above structure, when the mold is closed, the lower main mold 320 is pressed to the mold closing position by the upper mold 400 and the first elastic member 350 is compressed downward. After the pin molding is completed, when the mold is opened, the lower main mold 320 can be reset upward by the first elastic member 350. Since the lower molding die surface 340 is arranged on the lower main mold 320 and the lower cutting die 330, the lower main mold 320 that is reset upward can make the electronic components separate from the part of the lower molding die surface 340 on the lower cutting die 330, so as to prevent the electronic components from sticking to the lower mold 300.

[0047] In the embodiment, the upper mold 400 further includes an upper ejector block 450 and a second elastic member 460. The upper ejector block 450 can be movably arranged on the upper main mold 420, and the upper ejector block 450 and the workpiece placement position 321 are opposite to each other in the upper and lower directions. The second elastic member 460 is arranged between the upper ejector block 450 and the upper mold base 410 and is used to enable the upper ejector block 450 to reset downward. With the above structure, when the mold is closed, the upper ejector block 450 can be pushed upward by the electronic component to give way, and the upper ejector block 450 compresses the second elastic member 460 upward. After the mold is opened, the upper ejector block 450 can be reset downward by the second elastic member 460, thereby ejecting the electronic component downward and escaping from the upper molding die surface 440 of the upper main mold 420, so as to prevent the electronic component from sticking to the upper mold 400.

[0048] In the embodiment, the first elastic member 350 and the second elastic member 460 may be springs, or structures such as spring sheets and rubber columns.

[0049] In the embodiment, the two lower cutting dies 330 enclose and form a lower sliding groove, the lower main die 320 is slidably arranged in the lower sliding groove, the left and right sides of the lower end of the lower main die 320 are respectively provided with first flange parts 322, and the two lower cutting dies 330 respectively limit the two first flange parts 322 to the lower die seat 310. With the above structure, the lower sliding groove is formed by the two lower cutting dies 330, and the lower main die 320 is limited by the two lower cutting dies 330, so that the movable connection of the lower main die 320 can be realized with a simple structure, and the lower main die 320 can be removed after the two lower cutting dies 330 are removed, and the removal is convenient.

[0050] In the embodiment, the upper main mold 420 is provided with an upper slide groove, the upper top block 450 is slidably arranged in the upper slide groove, the left and right sides of the upper end of the upper top block 450 are respectively provided with second flange portions 451, and the upper end surface of the upper main mold 420 respectively limits the two second flange portions 451 to the upper mold base 410. Through the above structure, the movable connection of the upper top block 450 can be realized with a simple structure.

[0051] In the embodiment, the workpiece placement position 321 is a strip groove extending forward and backward, the front end of the strip groove is provided with a workpiece output port, and the rear end of the strip groove is provided with a workpiece input port. The pin forming machine also includes a loading mechanism 600 and a unloading mechanism 700. The loading mechanism 600 is used to input electronic components one by one into the workpiece input port and push them forward, and the unloading mechanism 700 is used to receive electronic components pushed out from the workpiece output port. The workpiece placement position 321 is set as a strip groove extending forward and backward, and through the setting of the loading mechanism 600 and the unloading mechanism 700, the electronic components can be moved along the strip groove to complete the feeding, pin forming and the final discharge. The flow structure is simple, which is conducive to simplifying the structure of the forming machine.

[0052] In an embodiment, the loading mechanism 600 includes a loading base 610 and a pushing assembly 620. The loading base 610 is provided with a loading chute 611 extending forward and backward and opening at the front and rear ends. The front end opening of the loading chute 611 is connected to the workpiece input port of the workpiece placement position 321. The pushing assembly 620 includes a pushing rod 621 and a first front and rear drive 622. The pushing rod 621 is arranged front and rear and can be inserted into the loading chute 611 from the rear end opening of the loading chute 611. The first front and rear drive 622 is connected to the pushing rod 621 and is used to drive the pushing rod 621 to move forward and backward. When loading electronic components, the electronic components can be placed at the rear end of the loading chute 611 first, and then the first front and rear drivers 622 drive the push rod 621 to move forward and backward, and the electronic components are pushed forward by the push rod 621. The electronic components are continued to be fed into the rear end of the loading chute 611 in sequence, so that the electronic components can enter the workpiece placement position 321 in the form of a queue and be sent forward from the workpiece placement position 321 in the form of a queue, thereby realizing assembly line production with high efficiency.

[0053] In the embodiment, the unloading mechanism 700 includes an unloading seat 710 and a second front-rear driver 720. The unloading seat 710 is provided with an unloading chute extending forward and backward and at least opening at the rear end. The rear end opening of the unloading chute is opposite to the workpiece output port of the workpiece placement position 321. The second front-rear driver 720 is connected to the unloading seat 710 and is used to drive the unloading seat 710 to move forward and backward. After the pins of the electronic components are formed, when unloading, the unloading seat 710 can be driven by the second front-rear driver 720 to move backward so that the rear end opening of the unloading chute is docked with the workpiece output port. After the pins of the electronic components are formed, the unloading seat 710 can be directly received by the unloading seat 710. After receiving a number of electronic components, the unloading seat 710 can be driven to move forward again so that it can dock with the loading mechanism of the next process device.

[0054] It is conceivable that the loading mechanism 600 and the unloading mechanism 700 are not limited to the above-mentioned embodiments. For example, the loading mechanism 600 and the unloading mechanism 700 use a robot to load and receive the electronic components with completed pin forming.

[0055] In the embodiment, the lower cutting die 330 is provided with a chip guide surface 332, which is located on the side of the lower blade portion 331 away from the lower main die 320 and is tilted downward. The lower cutting die 330 is provided with a chip discharge chute 800 on the side away from the lower main die 320, and the lower end of the chip guide surface 332 is arranged opposite to the entrance end of the chip discharge chute 800. With the above structure, after the upper and lower blade portions are cut, the cut pin chips can quickly leave through the chip guide surface 332 and enter the chip discharge chute 800, thereby preventing the pin chips from falling randomly.

[0056] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
