Description

本発明はプラスチック成形用金型の分野に関し、具体的にはプラスチック成形用金型に付着する不要なプラスチックに対する回収装置である。 The present invention relates to the field of plastic molding dies, and specifically is a recovery device for unnecessary plastics adhering to plastic molding dies.

プラスチック成形とは、様々な形状のプラスチックを製品またはブランクに作るプロセスであり、プラスチック成形では、通常、射出成形との方法が使用されるため、金型が不可欠であり、使用後、金型には不要なプラスチックが付着することは避けられない。現段階、金型に付着する不要なプラスチックを処理するとき、通常は、手作業で不要なプラスチックを削り取るため、人手がかかるだけでなく、削り取る効率も低く、削り取られた不要なプラスチックはすぐに収集されることができない。 Plastic molding is the process of making various shapes of plastic into products or blanks, and in plastic molding, the method with injection molding is usually used, so a mold is indispensable, and after use, it is made into a mold. It is inevitable that unnecessary plastic will adhere to it. At this stage, when processing unnecessary plastic that adheres to the mold, it is not only labor-intensive because the unnecessary plastic is usually scraped off manually, but the scraping efficiency is low, and the scraped unnecessary plastic is immediately removed. Cannot be collected.
