In addition, the height of the first protrusion 120 may be set to be smaller than the depth of the second groove 210, and when the first sub-mold 10 and the second sub-mold 20 are closed, a space between the top surface 122 of the first protrusion 120 and the bottom wall 212 of the second groove 210 is also present, so as to further prevent the first positioning structure 11 and the second positioning structure 12 from colliding and causing the first positioning structure 11 and the second positioning structure 21 to deform.
The second protrusion 220 has a second side 221 and a third side 222 perpendicular to the second side 221. Wherein the second side 221 is inclined to the first direction F1 and is simultaneously adjacent to the second sub-sidewall 2112 and the bottom wall 212, and the third side 222 is parallel to the first direction F1 and is adjacent to the bottom wall 212. The number of the second side surfaces 221 may be one, and the number of the second side surfaces 221 may be two, and the two second side surfaces 221 are adjacent to each other. Specifically, one second side surface 221 is connected to a side of the other second side surface 221 facing the first sub-mold 10 such that the two second side surfaces 221 are adjacent to each other.

For example, the view of the third protrusion 230 along the first direction F1 may be triangular, and then the third groove 140 is also triangular; for another example, the view of the third protrusion 230 along the first direction F1 may be a square or a rectangle, and then the third groove 140 is also a square or a rectangle; also for example, the view of the third protrusion 230 in the first direction F1 may be other polygons, and the third groove 140 may also be the same other polygons.
