The pressure blocks 141 are provided with stepped surfaces 142. The two sides of the side slider 140 can slide against the stepped surfaces 142 of the corresponding pressure blocks 141. Through the cooperation of the side slider 140 and the inclined wedge block 28, the side slider 140 moves along the stepped surfaces 142 towards the side of the sleeve 3 in the sleeve forming area to stamp and form the side of the sleeve 3.

[0021] The lower die 2 includes a lower die base 20, a lower pad 21, a lower clamping plate 22, a lower back plate 23, a lower template 24, a lower die floating forming punch 25, a mandrel 26, a mandrel core-pulling mechanism 27, a wedge block 28, and a support mechanism 29. The lower template 24 is provided with the lower die floating forming punch 25, which is positioned opposite to the upper die floating forming punch 13. The lower die floating forming punch 25 is symmetrically provided with wedge blocks 28 on both sides of the lower die floating forming punch 25. The wedge blocks 28 are positioned opposite to the upper die. The lateral shifting mechanism 14 forms a sleeve side forming mechanism. The lower template 24 is provided with a core rod pulling mechanism 27 and a support mechanism 29. The core rod pulling mechanism 27 is connected to the core rod 26, and the core rod 26 is aligned with the support mechanism 29. The core rod 26 and the support mechanism 29 form a sleeve fixed station on the lower template 24. The upper mold floating forming punch 13, the lower mold floating forming punch 25, and the sleeve side forming mechanism form a sleeve forming area, which is located in the sleeve fixed station.

[0022] The core rod pulling mechanism 27 includes a cylinder 270, a cylinder seat 271, a connecting rod 272, a core rod fixing seat 273, and a positioning rod 274. The cylinder seat 271 is located on the side of the lower template 24, and the cylinder 270 is mounted on the cylinder seat 271. The output end of the cylinder 270 is connected to the connecting rod 272. The core rod fixing seat 273 is mounted on the lower template 24, and the core rod 26 is mounted in the core rod fixing seat 273. The positioning rod 274 is located above the core rod 26 and is used to position the core rod 26.

[0024] In use, the sleeve 3 is placed in the sleeve fixing station, with the end of the sleeve 3 fitted onto the mandrel 26. The part of the sleeve 3 to be stamped is located in the sleeve forming area. The press drives the upper die 1 to press down, and the upper die floating forming punch 13 and the lower die floating forming punch 25 respectively flatten the upper and lower surfaces of the part of the sleeve 3 to be stamped. At the same time, the side slide block 140 cooperates with the wedge block 28, and the side slide block 140 stamps and forms the side of the part of the sleeve 3 to be stamped. After the end of the sleeve 3 is stamped and formed, the upper die 1 returns to its original position, the cylinder 270 is activated, and the mandrel 26 moves along the axial direction of the sleeve 3, causing the sleeve 3 to be removed from the mandrel 26. The cylinder 270 replaces manual core pulling of the mandrel 26. During the core pulling process, the force applied to the mandrel 26 is uniform, which not only prevents the sleeve 3 from being deformed by the force during the core pulling process, but also reduces the labor intensity of manual labor. The use of the molding die of this invention to produce the continuous firing clip sleeve for ligation surgery improves the pass rate of the continuous firing clip sleeve for ligation surgery.
