The needling position a and the needling preparation position B are distributed along the length direction of the first guide rail 111. At least two core mold bases 112 are slidably provided on the first rail 111, and one core mold assembly 10 is provided on one core mold base 112. A first drive mechanism 113 is connected to the at least two core mold bases 112, and can be used to drive the at least two core mold bases 112 to switch between the needling position a and the needling preparation position B.
In practical applications, the core mold base 112 can be used to fix the core mold assembly 10, and in the case where the first driving mechanism 113 drives the core mold base 112 to switch between the needling position a and the needling preparation position B, the core mold assembly 10 on the core mold base 112 can be correspondingly driven to switch between the needling position a and the needling preparation position B. Since the needling position a and the needling preparation position B are distributed along the length direction of the first guide rail 111, switching between the needling position a and the needling preparation position B can be completed with high switching efficiency in the case where the core mold base 112 slides along the first guide rail 111.

Specifically, the first needling preparation position B1 and the second needling preparation position B2 are arranged at both ends of the first guide rail 111, so that the first needling preparation position B1 and the second needling preparation position B2 can be far away from each other, and needling preparation operations can be conveniently performed on the first needling preparation position B1 and the second needling preparation position B2. By disposing the needling position a between the first needling preparation position B1 and the second needling preparation position B2, the distances between the first needling preparation position B1, the second needling preparation position B2, and the needling position a can be made short, so that the switching efficiency of the core mold assembly 10 between the first needling preparation position B1 and the needling position a, and the switching efficiency of the core mold assembly 10 between the second needling preparation position B2 and the needling position a can be improved.
As shown in fig. 3, the first driving mechanism 113 may include: a first driver 1131 and a second driver 1132; wherein the first drive 1131 is coupled to at least one mandrel base 112, the first drive 1131 may be used to drive the mandrel base 112 between a first piercing preparation position B1 and a piercing position a.

In practical applications, the third driving member may be used to drive the first lead screw 1133 to rotate, and since at least two core mold bases 112 are threadedly connected to the first lead screw 1133, the rotation of the first lead screw 1133 may drive the at least two core mold bases 112 to move along the length direction of the first lead screw 1133. Since the first lead screw 1133 is parallel to the first guide rail 111, the first lead screw 1133 can drive the two core mold bases 112 to move along the longitudinal direction of the first guide rail 111, and switch between the needling preparation position B and the needling position a. Since the distance between two adjacent core mold bases 112, the distance between the first needling preparation position B1 and the needling position a, and the distance between the second needling preparation position B2 and the needling position a are equal, while the first lead screw 1133 drives one core mold base 113 to switch from the needling position a to the first needling preparation position B1 for needling preparation, the other core mold base 112 can also be driven to switch from the second needling preparation position B2 to the needling position a, so that the preform on the core mold base 112 can be subjected to needling operation, the waiting time of the needling assembly 12 is reduced, and the needling processing efficiency of the preform is improved.
