The technical scheme of the invention has the following advantages:
1.

When the petal pieces are mounted on the petal fixing plate, the petal pieces are inserted into the mounting cavity, the positioning surface is enabled to be abutted against the positioning matching surface in the inserting process, and then the petal fixing plate is rotated by a set angle relative to the petal pieces so that the protruding blocks slide into the corresponding annular grooves to be clamped, so that the petal pieces can be effectively prevented from being mounted erroneously when the petal pieces are mounted on the petal fixing plate, the mounting position of the petal pieces can be guaranteed to be accurate, and the accuracy of produced products can be guaranteed.
2. According to the positioning assembly of the die, at least two positioning surfaces are arranged on the outer circumferential surface of the petal piece at intervals along the circumferential direction of the petal piece, and the distance from one positioning surface to the axis of the petal piece is different. The petal pieces are only inserted into the mounting cavity in the uniquely determined direction, and the mounting position of the petal pieces can be effectively ensured to be accurate.
3. According to the positioning assembly of the mold, the number of the positioning surfaces is two, and the positioning surfaces are symmetrically arranged on the circumferential direction of the outer circumferential surface of the petal piece, so that the accurate mounting position of the petal piece can be effectively ensured, the high processing cost of the petal piece caused by processing more positioning surfaces can be prevented, and the processing cost is further saved.
4. The positioning component of the die has the advantages that the intersecting edges are round-angle edges, so that friction between the intersecting edges and the convex blocks when the intersecting edges move in the convex blocks can be effectively reduced, the convex blocks can slide into the annular grooves more conveniently, and accuracy errors between the positioning matching surfaces and the positioning surfaces caused by friction between the intersecting edges and the convex blocks can be reduced, for example, the positioning matching surfaces are not abutted any more.
5. The positioning assembly of the die comprises a first section of groove in the rotation set angle and a second section of groove smoothly connected with the first section, wherein the distance between the bottom of the second section of groove and the axis of the petal piece is larger than that between the positioning matching surface and the axis of the petal piece.

6. According to the positioning assembly of the die, the convex blocks are smoothly connected with the side wall of the mounting cavity, so that larger friction force can be prevented when the convex blocks slide between the positioning surface and the annular groove, and loss of the die positioning assembly is prevented.
