Description

Technical Field

[0001] The utility model relates to a rapid prototyping tooling for a valve stent. Background Art

[0002] During the production process of a heart valve stent, a high requirement is imposed on the angle of the pick. A suitable mold is needed during production. In the past, when making the mold, due to repeatedly adjusting the pick angle, a large number of molds had to be made for trial, resulting in a large amount of time and money being spent. In addition, it was very difficult to accurately control the pick angle. Content of the Utility Model

[0003] The utility model provides a rapid prototyping tooling for a valve stent, which can rapidly pick the heart valve stent, saving time and improving efficiency.

[0004] The purpose of the utility model is achieved as follows:

[0005] A rapid prototyping tooling for a valve stent includes a disc-shaped base. A through hole is opened at the center of the base. A mandrel passes through the through hole of the base. A circle of shaft seats is fixed on the outer side of the top of the base. A sleeve is arranged between the outer side of the shaft seat and the mandrel. The top end of each sleeve is close to the mandrel. The bottom end of the sleeve is hinged to a rotating shaft. The rotating shaft is perpendicular to the sleeve and passes through the shaft seat, driving the sleeve to turn over.

[0006] An axially opening is formed at the top of the sleeve.

[0007] The distances between adjacent shaft seats are equal.

[0008] Angles are engraved on the side surfaces of the shaft seats.

[0009] The beneficial effects of the utility model are as follows:

[0010] A rapid prototyping tooling for a valve stent adjusts the position of the sleeve according to the pick angles of different stents during the forming process by arranging a rotatable sleeve, thereby rapidly completing the pick work. A set of molds can complete the shaping of heart valve stents of various specifications. Using this rapid prototyping tooling for shaping greatly improves the pick efficiency and saves time and costs. Description of the Drawings

[0011] Figure 1 It is a structural schematic diagram of the utility model.

[0012] In the figure: base 1, mandrel 2, shaft seat 3, sleeve 4, rotating shaft 5. Detailed Embodiment

[0013] Refer to Figure 1, the utility model relates to a rapid prototyping tooling for a valve stent, which comprises a disc-shaped base 1. A through hole is opened at the center of the base 1, and a mandrel 2 passes through the through hole of the base 1. A circle of shaft seats 3 are fixed on the outer side of the top of the base 1, and the distances between adjacent two shaft seats 3 are equal. A sleeve 4 is arranged between the outer side of the shaft seat 3 and the mandrel 2. The top end of each sleeve 4 is close to the mandrel 2, the bottom end of the sleeve 4 is hinged to a rotating shaft 5, the rotating shaft 5 is perpendicular to the sleeve 4, and the rotating shaft 5 passes through the shaft seat 3, so that the sleeve 4 can be turned over with it.

[0014] Angles are engraved on the side surface of the shaft seat 3, so as to read out the angle of rotation of the sleeve 4.

[0015] When the valve stent is formed, its main body is arranged on the mandrel 2, and the top of the sleeve 4 is axially drilled, and the drilled part is used for the thorns on the valve stent to extend into it.

[0016] When this rapid prototyping tooling for a valve stent is used, first connect the stent to the mandrel, then adjust the angle of the sleeve according to the angles of each thorn on the heart valve stent, and manually insert each thorn into the hole at the top of the sleeve. During this period, the position of the sleeve can be conveniently adjusted, so as to quickly complete the work of lifting the thorns, and then realize the rapid shaping of the valve stent.
