[0045] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0046] Working principle, see Fig.10 and Fig.11 First, the mounting seat 1, the support seat 2, and the stabilizing seat 3 are installed at the designated position on the side of the mold by bolts. The subsequent personnel assemble the insert on the insert block 24, and then start the transmission cylinder 4 to push the locking block 25 to move, and cooperate with the connection between the locking block 25 and the assembly seat 12, so as to drive the assembly seat 12 to follow the displacement, so as to push the insert to the designated position of the mold cavity for pre-embedding;

[0047] When the transmission cylinder 4 is damaged or the assembly seat 12 is damaged, the transmission screw 30 is first rotated with the help of an external hexagonal wrench, and the connection between the transmission screw 30 and the displacement push plate 32 can be used to drive the extrusion plate 33 to move upward along the transmission screw 30, and the arrangement of the extrusion slope and the pressure slope is used. When the extrusion plate 33 moves upward, the distance between the two pressure slopes gradually increases, and the guide plate B27 is pushed by the rebound of the return spring 28, so that the pressure plate 29 is always in contact with the extrusion plate 33, and when the guide plate B27 is displaced, it can drive the locking rod 26 to move into the locking block 25, so as to release the connection with the matching lock groove 13;

[0048] And in the process of the two guide plates B27 approaching each other, since the guide plate B27 is also movably connected inside the linkage groove 42, the displacement of the guide plate B27 inside the linkage groove 42 can be used to push the linkage plate 41, so that the linkage plate 41 drives the linkage shaft 38 to rotate, and cooperates with the connection between the linkage shaft 38 and the conductive plate 39, so that the conductive plate 39 pushes the guide seat 35, causing the guide seat 35 to slide under the support of the linear slide rod 34, thereby driving the two limit arc plates 36 away from each other and disengaging from the locking shaft 37, and then the locking block 25 can be moved out of the locking groove 13 to form a separation between the transmission cylinder 4 and the assembly seat 12 for subsequent maintenance.
