[0002] In the current industrial production process, especially when involving processes such as injection molding, the product after molding will usually leave a part of the excess material, commonly known as "water gap", which is the connecting part between the product and the mold injection system, and needs to be cleaned after the product is demolded to ensure the appearance of the product is neat and the functional integrity.
[0003] At present, the removal of the water gap mainly relies on manual operation, that is, production employees use hand tools to cut and trim the water gap of each product. However, this manual cutting method has unstable cutting quality, as it depends on the manual operation skills and experience of the employees, and problems such as uneven cutting surface, excessive or insufficient residual parts may occur during the cutting process, resulting in uneven product appearance quality, affecting the overall appearance and performance of the product. Manual cutting requires employees to process the water gap of each product one by one, which is slow, especially in mass production, and cannot meet the needs of efficient production, which directly prolongs the production cycle of the product and reduces the overall production capacity. Long-term repetitive manual operation can easily make employees feel tired, which not only affects work efficiency but also increases the risk of operation errors, further affecting product quality.
