The multi-axis robot arm 4 drives the second suction assembly 41 on it to simultaneously adsorb and fix the eight injection molded parts 7 on the transfer table 31 and transfer them to the guide rail 62. Under the push of the pusher assembly 61, the injection molded parts 7 are sent to the guide rail 62. The material is fed onto the base 51, and the drive cylinder 54 drives the punch assembly 53 to descend and punch the injection molded product 71 out of the injection molded part 7. Then, the lifting element 516 lifts up the skeleton waste 72, and the subsequent injection molded part 7 pushes the skeleton waste 72 away and discharges it from the waste outlet groove 511 along the guide rail 62, completing the material discharge operation. The whole process does not require manual intervention and can be continuously and fully automatically processed.

The overall capacity is much higher than that of manual or semi-automatic equipment. It is suitable for large-scale deployment of production lines, adapts to batch high-speed punching and separation, significantly improves product punching efficiency, reduces off-center cutting, cracks, and burrs, improves the consistency of finished product appearance and precision, ensures the complete separation of injection molded product 71, and reduces the risk of residual material and scratches.

5. The automatic feeding and punching equipment for injection molded parts according to claim 1, characterized in that, The second suction component includes a flat plate frame, on which multiple suction heads are fixed.
6. The automatic feeding and punching equipment for injection molded parts according to claim 1, characterized in that, The punching die includes a base, a stand, and a punch assembly. The stand is fixedly connected to the base, and a drive cylinder is mounted on the stand. The output end of the drive cylinder is fixedly connected to the punch assembly. The base is provided with a waste outlet groove and a product outlet groove. The guide rail is fixed on the base. The drive cylinder drives the punch assembly to move downward to punch the injection molded product out of the injection molded part and discharge it from the product outlet groove. The waste material of the injection molded part is discharged from the waste outlet groove.
7. An automatic feeding and punching device for injection molded parts according to claim 6, characterized in that, A contour block is embedded in the base, the product outlet groove is located on the contour block, and the contour block has supporting protrusions on both sides of the product outlet groove. A stop bar is embedded on both sides of the base in the direction of movement of the injection molded part. A lifting element is provided on both sides of the base in the contour block. A positioning block is provided on the base, and the guide rail is distributed on both sides of the positioning block. The injection molded part is pushed along the guide rail between the two positioning blocks. The stop bar is used to position the injection molded part. After the product is punched, the lifting element lifts the skeleton waste and discharges it from the waste outlet groove along the guide rail.
8. An automatic feeding and punching device for injection molded parts according to claim 7, characterized in that, The punch assembly includes an upper plate, a middle plate, a lower plate, a knife holder, and a punching blade. The punching blade is fixed on the knife holder, which is embedded in the lower plate and fixedly connected to the middle plate. A matrix of guide posts is fixed on the base. The guide posts slide through the upper plate, the middle plate, and the lower plate, which are sequentially fixedly connected. The output end of the drive cylinder is fixedly connected to the upper plate.
9. An automatic feeding and punching device for injection molded parts according to claim 8, characterized in that, The bottom of the blade holder is provided with a downward pressing protrusion that matches the injection molded product on the injection molded part. The punching blade is provided with punching cutting edges on both sides of the downward pressing protrusion, and the bottom of the blade holder is provided with a sprue groove that matches the injection molded part.
10. An automatic feeding and punching device for injection molded parts according to claim 1, characterized in that, The feeding assembly includes a linear guide module, a slide block on the linear guide module, a lifting cylinder fixed on the slide block, a feeding frame fixed at the output end of the lifting cylinder, and a feeding groove on the top surface of the feeding frame.
