Description

Technical Field

[0001] The utility model relates to the technical field of surface treatment of injection molded parts, in particular to a scraping device for a water outlet of an injection molded part. Background Art

[0002] Thin-walled injection molded parts usually have multiple different types of sprues remaining, which need to be processed to meet the surface quality requirements of the product. For thin-walled injection molded parts with multiple different types of sprues remaining, the existing method of removing sprues is mainly to manually cut off the sprues from the root with pliers. For sprues that cannot be cut with pliers, the sprues are manually scraped away with a spatula. Manually removing sprues with pliers has the problem of difficult to accurately control the cutting position. If the cutting position is too forward, the root sprue will remain. If the cutting position is too backward, the product plastic will be cut off, resulting in poor sprue removal. Manually scraping sprues with a spatula has the problems of large scraping force and difficulty in accurately controlling the scraping force direction. Large scraping force increases the labor intensity of workers. Inaccurate control of the scraping force direction will scratch the product surface, resulting in poor scraping of sprues. It can be seen that manual removal of sprues has problems such as low yield rate, low production efficiency, and high labor intensity of workers. Utility Model Content
