Fig. 1 is a front view of the shaping mold according to the present embodiment; fig. 2 is a schematic structural view of the shaping mold provided in this embodiment; fig. 3 is a front view of the second mold 2 according to the present embodiment. As shown in fig. 1 to 3, the shaping mold includes a first mold 1, a second mold 2, and a slide rail 3. Wherein, first mould 1 is including the first mount pad 11 and the first forming roll 12 of rotation connection, and the outer peripheral face of first forming roll 12 is the cambered surface of indent, and second mould 2 is including fixed connection's second mount pad 21 and second forming roll 22, and the outer peripheral face of second forming roll 22 is the cambered surface of indent, and the axis of first forming roll 12 and second forming roll 22 is parallel and relative setting to form accommodation space, accommodation space is used for the shaping pipe. The shaping mould further comprises a sliding rail 3, and the first mounting seat 11 and the second mounting seat 21 are both arranged on the sliding rail 3 in a sliding manner so as to adjust the distance between the first forming roller 12 and the second forming roller 22. The accommodating space formed by the first forming roller 12 and the second forming roller 22 with the concave arc-shaped surfaces can adjust the conduit with unqualified contour so as to meet the use requirement. At the same time, to accommodate catheters of different sizes, it is also possible to adapt the spacing between the first forming roll 12 and the second forming roll 22 according to the adjustment.

Specifically, in the present embodiment, two first forming rollers 12 and two second forming rollers 22 having concave arc surfaces are arranged in parallel, and a receiving space for adjusting the shape of the outer contour of the conduit is formed therebetween, when the shaping mold is used, the conduit is firstly passed through the receiving space, the conduit is in contact with the outer contours of the first forming rollers 12 and the second forming rollers 22, in order to reduce the resistance force applied when the conduit passes through the receiving space, the first forming rollers 12 can rotate around the axial direction thereof, and the second forming rollers 22 are fixed for ensuring the forming effect. The outer contour of the conduit is corrected through the two inward-concave arc surfaces, the conduit provided by the embodiment is the conduit before unshaped, and the corrected outer contour of the conduit can meet the market requirement.

In order to rotatably connect the first forming roll 12 with the first mounting seat 11, a connecting rod 13 is arranged at one end of the first forming roll 12, a first mounting hole is formed in the end surface of the first mounting seat 11, and the connecting rod 13 is rotatably arranged in the first mounting hole, so that the first forming roll 12 can rotate around the axis of the first forming roll 12; in order to fixedly connect the second forming roller 22 with the second mounting seat 21, a threaded rod 23 is arranged at one end of the second forming roller 22, a second mounting hole is formed in the end face of the second mounting seat 21, the free end of the threaded rod 23 is in threaded connection with the second mounting hole, namely, after the threaded rod 23 is screwed into the second mounting hole, the second forming roller 22 and the second mounting seat 21 are fixedly connected.
