A catheter manufacturing apparatus is disclosed. The catheter manufacturing apparatus is configured such that an upper mold, a lower mold, and support members, which have straight pins and oblique pins formed on the front ends thereof, are located at predetermined positions at scheduled time intervals, the upper mold and the lower mold are coupled to each other when pre-manufactured tubes are fitted onto the tips of the straight pins, silicone liquid is automatically injected into the catheter manufacturing apparatus, and catheters are automatically separated from the catheter manufacturing apparatus, whereby it is possible to automatically manufacture the catheters with a minimal defect rate within the shortest period of time. The manufacture of Y-shaped branches and the coupling of the Y-shaped branches to tubes are carried out in one step, and manufactured catheters are automatically separated from molds, thereby reducing the defect rate and remarkably improving the yield rate, unlike a conventional catheter manufacturing apparatus, which is configured such that a Y-shaped branch constituting a catheter is manufactured using an additional mold, is manually separated from the mold, is manually moved, and is then coupled to a tube.本發明涉及一種導管製造裝置,目的在於提供一種上部模具、下部模具和前端形成直翹片及斜翹片的支架主體基於日程設置的時間間隔位於設置的軌跡上,作業人員將事先製作的管體插入直翹片的前端時,模具封閉,矽膠自動注入,導管脫落,在最短時間內確保不合格率最低的情況下自動製造導管的導管製造裝置。與對構成導管的Y字形分叉部,通過另外的模具製造,從模具上人工取下並人工移動,從而再次組裝管體的傳統裝置不同,採用本發明,一步完成Y字形分叉部的製造和管體的結合,只要把自動製造出來的導管從模具中取下即可,從而使產品的不合格率顯著下降,具有大幅度改善收益率的優點。
