After printing, the product is manually removed from the placement slot. Existing injection molding product printing equipment has the following problems: for small and numerous injection molded products, after printing or other operations are completed, the products need to be manually removed from the placement slot, which wastes time and results in low production efficiency.

Then, the microcontroller 2 controls the printing machine 6 to print on the injection molded product. After the printing is completed, the positioning mechanism 7 is driven by the motor 8 to release the positioning state of the injection molded product.

[0026] Then, turn on motor 4. The output shaft of motor 4 drives the worm gear 353 to rotate. The rotation of the worm gear 353 drives the lead screw 351 to rotate through the meshing worm wheel 352. Under the restriction of the limit rod 31, the rotation of the lead screw 351 drives the threaded sliding seat 32 to move upward. The movement of the sliding seat 32 drives the ejector rod 33 to move upward along the sliding hole 34. The ejector rod 33 ejects the injection molded product out of the placement groove 5. Then, turn on the electric push rod 362. The telescopic shaft of the electric push rod 362 drives the push plate 363 to move to the left, pushing the injection molded product ejected from the placement groove 5 by the ejector rod 33 into the collection box on the left side of the processing table 1, thus completing the unloading of the injection molded product.
