With the above arrangement, the trigger insert 140 can drive the trigger spring 120 to move along the moving direction of the movable template.

[0038] Preferably, a spring 150 is provided at one end of the trigger spring slot 211 away from the trigger insert, and the spring 150 is against the trigger spring 120 and applies a horizontal force toward the trigger 110 to the trigger spring 120; and when the trigger spring 120 is subjected to a horizontal force toward the inclined top base plate 210, the spring 150 is squeezed and the trigger spring 120 can completely enter the trigger spring slot 211.

[0043] Specifically, Figure 6-11 As shown, the mold closing state and mold opening movement process of the inclined buckle machine combined with the core pulling mechanism are as follows:

[0044] In the mold closing state: the trigger spring block 120 protrudes out of the trigger spring block groove 211, and the lower end surface of the protruding portion of the trigger insert 140 abuts against the upper end surface of the trigger spring block 120;

[0045] The mold opening movement process includes:

[0046] First, the movable plate 300 moves vertically downward. At this time, the movable plate 300 drives the locking machine 110 and the locking machine insert 140 to move vertically downward. The locking machine insert 140 drives the locking machine spring block 120 to move vertically downward. The locking machine spring block 120 drives the inclined top bottom plate 210 to move vertically downward, so that the inclined top rod 240 moves along the guide of the inclined top guide block 250 (i.e., tilted to the left in the vertical direction), so that the inclined top 220 moves along the core pulling direction;

[0047] Then, when the lower end surface of the avoidance portion 131 of the bolt insertion rod 130 contacts the inclined surface of the bolt spring block 120, as the bolt spring block 120 continues to move downward, the lower end surface of the avoidance portion 131 slowly pushes the bolt spring block 120 into the bolt spring block groove 211;

[0048] Finally, when the trigger spring block 120 is completely pressed into the trigger spring block groove 211 by the trigger rod 130, the trigger insert 140 is separated from the trigger spring block 120, and the inclined top bottom plate 210 no longer moves. At this time, the inclined top 220 is separated from the air conditioner base 600, completing the inclined top core pulling.

Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
