[0019] In one embodiment of the present invention, reference Figure 1~Figure 2As shown, a mechanism for automatically separating scrap parts from a progressive die is provided, comprising a base plate 100, an upper die base 200, a lower die base 300, and a drive device. The lower die base 300 is disposed on the base plate 100, and the upper die base 200 is disposed above the lower die base 300. The drive device is connected to the upper die base 200 to drive the upper die base 200 toward or away from the lower die base 300. The mechanism also includes a product chute 400, a scrap discharge assembly 500, a solenoid valve reversing switch 600, a reversing solenoid valve 610, a push button 620, and a drive cylinder 540. The product chute 400 is disposed on the base plate 100, with one end of the product chute 400 located at the discharge end of the lower die base 300 and the other end extending downward along the outer side of the lower die base 300. A reversing solenoid valve 610 is mounted on the lower die base 300. A solenoid valve reversing switch 600 is mounted on the reversing solenoid valve 610 and is used to control the reversing of the reversing solenoid valve 610. A push button 620 is mounted on the upper die base 200 and is located directly above the solenoid valve reversing switch 600. The push button 620 is used to activate or deactivate the solenoid valve reversing switch 600. A waste discharge assembly 500 is slidably mounted on the base plate 100 and is located on one side of the product chute 400. A drive cylinder 540 is mounted on the base plate 100 and is connected to the drive cylinder 540. The reversing solenoid valve 610 controls the drive cylinder 540 to drive the waste discharge assembly 500 to slide along the base plate 100 toward or away from the product chute 400. In this embodiment, the upper die base 200 and the lower die base 300 are driven by a drive device to move closer to each other to perform stamping and forming of the product. During the stamping and forming process, in-mold waste is generated in the product. Therefore, when the upper die base 200 and the lower die base 300 are close to each other, the pressing key 620 presses the solenoid valve reversing switch 600, so that the reversing solenoid valve 610 is reversed, and then the reversing drive cylinder 540 is used to drive the waste material unloading assembly 500 to approach the product chute 400, to receive the waste material punched from the lower die base 300. When the upper die base 200 and the lower die base 300 are away from each other, the pressing key 620 no longer presses the solenoid valve reversing switch 600, and the reversing solenoid valve 610 is reset, thereby driving the waste material unloading assembly 500. 00 is away from the product chute 400. At this time, the molded product after stamping is demolded and falls into the product chute 400. The automatic separation mechanism of waste parts in the progressive die provided by the utility model can make the waste leave the mold along the waste discharge component 500 when the product is stamped, and the molded product leaves the mold along the product chute 400. The time difference between the sliding of the product and the waste is utilized to achieve the purpose of sorting the product and the waste. When the product falls, it will not meet the waste, thereby achieving the purpose of sorting the product and the waste and improving production efficiency.

[0020] Specifically, refer to Figure 1~Figure 2As shown, the waste discharge assembly 500 includes two waste discharge assemblies 500, which are respectively arranged on either side of the product chute 400. Both waste discharge assemblies 500 are connected to a reversing solenoid valve 610. The reversing solenoid valve 610 controls the driving cylinder 540 to drive the two waste discharge assemblies 500 to slide along the bottom plate 100 toward or away from the product chute 400. In this embodiment, when the solenoid valve reversing switch 600 is pressed by the pressing key 620, the two waste discharge assemblies 500 move toward the product chute 400, so that the two waste discharge assemblies 500 can cover the product chute 400, preventing waste from entering the product chute 400, causing the waste to mix with the molded product and increasing the difficulty of subsequent processing.

[0021] Specifically, refer to Figure 1~Figure 2 As shown, the waste unloading mechanism includes a waste chute 510, a slider 520, and a mounting base 530. The mounting base 530 is disposed on the base plate 100, and the slider 520 is mounted on the mounting base 530. The waste chute 510 is connected to the slider 520.

One end of the waste chute 510 is disposed on one side of the product chute 400, and the other end extends downward along the outer side of the product chute 400 and is perpendicular to the product chute 400. In this embodiment, the air intake direction of the driving cylinder 540 is controlled by the reversing solenoid valve 610, and the driving slider 520 slides on the mounting seat 530, so that the waste chute 510 approaches or moves away from the product chute 400, thereby collecting the waste dropped in the mold.

[0022] Specifically, refer to Figure 1~Figure 2 As shown, both sides of the product chute 400 are provided with an air-avoidance opening 410, which is used to avoid the waste chute 510. In this embodiment, the air-avoidance opening 410 is used to avoid the waste chute 510 so that the waste chute 510 can enter the lower die end of the lower die base 300.

[0023] Specifically, refer to Figure 1~Figure 2As shown, the lower die base 300 includes a lower die plate 310, a punching base 320, a floating material block 330, and an elastic member 340. The lower die plate 310 is disposed on the base plate 100, and the punching base 320 is disposed on the lower die plate 310. The lower die plate 310 is further provided with a mounting hole 311. The mounting hole 311 is located on a side of the punching base 320 away from the product chute 400. The floating material block 330 is vertically slidably disposed on the mounting hole 311. The elastic member 340 is disposed in the mounting hole 311, with one end of the elastic member 340 abutting the bottom of the mounting hole 311 and the other end abutting the floating material block 330. In this embodiment, the product is placed on the stamping seat 320, with one end of the product on the floating block 330. When stamping is performed, the upper die seat 200 presses the floating block 330, and the elastic member 340 is compressed to store elastic potential energy. The stamped waste falls into the waste chute 510. When the stamping is completed and the waste falls into the waste chute 510, the upper die seat 200 is reset, and the elastic potential energy of the elastic member 340 is released. The floating block 330 is driven by the elastic member 340 to bounce the formed product, causing the formed product to fall into the product chute 400, realizing fully automatic unloading.

[0024] Specifically, refer to Figure 1~Figure 2 As shown, the upper die base 200 includes an upper die plate 210, a stripper plate 220, a punching head 230, a blanking tool 240, a pressing head 250, and an elastic reset member 260. The upper die plate 210 and the drive device are two sections. The stripper plate 220 is arranged below the upper die plate 210. The elastic reset member 260 is arranged between the stripper plate 220 and the upper die plate 210, and the two ends of the elastic reset member 260 are respectively connected to the upper die plate 210 and the stripper plate 220. The punching head 230 is arranged on the stripper plate 220 and is located above the punching base 320. The pressing head 250 is arranged on the stripper plate 220 and is located above the floating block 330. The blanking tool 240 is arranged on the upper die plate 210 and is located on the side of the punching base 320 near the product chute 400. The blanking tool 240 cooperates with the punching base 320 to punch the product. In this embodiment, when stamping is performed, the upper template 210 drives the stripper plate 220 toward the lower die base 300. When the punching head 230 on the stripper plate 220 abuts against the punching base 320, the pressing head 250 on the stripper plate 220 presses the floating block 330, and the upper template 210 continues to descend, squeezing the elastic reset part 260. At this time, the punching tool 240 continues to descend, and the waste end of the product is punched and falls into the waste chute 510. The product is then reset and driven by the floating block to enter the product chute 400, realizing fully automatic waste separation and unloading.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
