This invention is concerning the shaping of plastic toothpicks with a brush. It contains one-by-one feed hoppers, one program-controlled device, one mold zone with dies for toothpicks with brush, one robotic arm, and one conveyor. As to mold zone with dies for toothpicks with brush, it comprises two semi-molds, upper and lower. At the proper joint on the feed hoppers is a compressed nitrogen tank with a gas pipe used to stabilize the injection rate of the melting blend moldflow while the raw materials are hot melted. In this way, toothpicks with brush will be produced after the process of feeding materials, melting, gas injection, stamping, dosing, mold releasing, producing the prototype, cooling, pitching, and rolling. It enables the production of toothpicks with brush to be more time- and energy-saving by rolling it with process dissociation procedure. Besides, while hot melting the raw materials by internally forming them in feed hoppers, nitrogen can be injected at the right moment to speed up melting blend moldflow up to 600mm of kinetic energy per second. As a result, the defective rate of the injection molding and demolding will be reduced, enhancing capability and ensuring overall quality.一種牙籤刷成型方法,其包含有:一與一進料斗、一可程式控制裝置、一內設有牙籤刷押出模之注模區、一機械手臂及一輸送台,其中注模區之牙籤刷押出模具有一上、下半模,於進料斗之一適位處連結設有一高壓氣體氮氣桶,於進料斗之一適位處設一供原料經熱熔時可穩定熔融混練物模流射出速度以形成氮氣射出方式具輸氣管之高壓氣體氮氣桶,藉此,經入料、進料、熔融注氣、沖壓灌注、脫模、雛品完成、冷卻定型、滾軋之製作程序即完成牙籤刷成品,令牙籤刷成品進行滾軋作業而達到分離加工更為省時省力之效益,而利用進料斗內塑原料熱熔的同時可適時注入氮氣以供熔融混練物模流射出速度可達到每秒約為600mm之動量,而達到減少牙籤刷注塑成型開模之不良率,相對提升產能及確保品質均一。a‧‧‧入料b‧‧‧進料c‧‧‧熔融注氣d‧‧‧沖壓灌注e‧‧‧脫模f‧‧‧雛品g‧‧‧冷卻h‧‧‧滾軋i‧‧‧成品
