The second clamping wedge 28 is fixedly connected to the locking cylinder 26, and both sides of the first clamping wedge 27 in the telescopic direction of the piston rod of the locking cylinder 26 are provided with outer edge portions 272 extending downward, and the two outer edge portions 272 are attached to the outer walls of the corresponding sides of the second clamping wedge 28, so that the first clamping wedge 27 can stably slide on the second clamping wedge 28.

More specifically, the length of the locking opening 271 in the sliding direction of the second clamping wedge 28 is smaller than the length of the relief opening 281 in the sliding direction of the second clamping wedge 28, so that after the locking cylinder 26 pulls the second clamping wedge 28 to move the end of the locking opening 271 on the first clamping wedge 27 away from the through hole 25 to abut against the bayonet 42 of the locking pin 41, the locking cylinder 26 can continue to pull the second clamping wedge 28 to slide so that the first clamping wedge 27 moves vertically upwards until the top of the first clamping wedge 27 abuts against the upper wall surface of the bayonet 42, thereby realizing the action of locking the corresponding locking pin 41, and the related locking process can refer to fig. 11A-11C. A baffle 282 is further arranged at one end, close to the locking cylinder 26, of the top of the second clamping wedge 28, and when the locking pin 41 needs to be unlocked, a piston rod of the locking cylinder 26 stretches out to drive the second clamping wedge 28 to reset; in the process of resetting the second clamping wedge 28, the first clamping wedge 27 firstly descends under the action of gravity, and then is driven by the baffle 282 to move together with the second clamping wedge 28, so that the resetting of the first clamping wedge 27 is realized, and the unlocking of the locking pin 41 is realized.

Further, the top of the mold changing plate 241 is fixedly connected with the guide plate 246 corresponding to the position of each second clamping wedge 28, and a guiding slot 283 is formed at the bottom of each second clamping wedge 28, and the second clamping wedge 28 is slidably disposed on the corresponding guide plate 246 through the guiding slot 283, so as to improve the sliding stability of the second clamping wedge 28.

According to the application, the upper die 4 and the lower die 3 carried by the horizontal moving part 12, the horizontal moving part 22 and the vertical moving part 23 are moved between different positions, and then the upper die 4 is locked and turned over by the locking turning part 24, so that the traditional core cooler is improved, and the purposes of conveniently cleaning the upper die 4 and reducing potential safety hazards during cleaning the upper die 4 are achieved.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
