The working principle and the working process of the invention are as follows:

after the equipment is started, the three-phase asynchronous motor 15 drives the driving wheel 17 to rotate clockwise through the right-angle steering gear box 16, and the driving wheel 17 drives the feeding turntable synchronous wheel 21 and the discharging turntable synchronous wheel 22 to rotate clockwise and the die separating turntable synchronous wheel 20 to rotate anticlockwise through the synchronous belt 19; pan feeding carousel synchronizing wheel 21 drives pan feeding carousel 1 clockwise rotation through pan feeding carousel rotation axis 2, divides mould carousel synchronizing wheel 20 to drive 3 counter-clockwise rotations of mould carousel through dividing mould carousel rotation axis 4, and ejection of compact carousel synchronizing wheel 22 drives ejection of compact carousel 5 clockwise rotations through ejection of compact carousel rotation axis 6.

In formal work, the front process automatically transfers products to a station notch of the feeding turntable 1, the products rotate towards the feeding turntable guide block 25 along with the clockwise rotation of the feeding turntable 1, and are pre-separated by the upper die and the lower die when rotating to the outlet of the feeding cutter 7, then the pre-separated products are driven to the upper lower die limit block 10 by the feeding turntable 1, the pre-separated products are blocked by the upper die limit block 10 and the lower die limit block 10, and therefore the mold splitting turntable 3 which rotates anticlockwise conveniently can more smoothly transfer the pre-separated products to the station notch of the mold splitting turntable 3.

When the product is just transferred to the split rotary table 3, the product is not clamped by the upper die elastic pressure head 903 and the lower die elastic pressure head 803, but when the product is driven to rotate towards the split rotary table guide block 26 by the split rotary table 3, the upper die pressing mechanism rotary table 902 and the lower die pressing mechanism rotary table 802 drive the upper die elastic pressure head follower wheel 905 and the lower die elastic pressure head follower wheel 805 to rotate towards the start ends of the low track section of the upper die elastic pressure head lifting annular guide rail 906 and the low track section of the lower die elastic pressure head lifting annular guide rail 806 respectively through the upper die elastic pressure head guide sleeve and the lower die elastic pressure head guide sleeve, and the upper die elastic pressure head follower wheel 905 and the lower die elastic pressure head follower wheel 805 gradually clamp the product respectively along with the upper die elastic pressure head lifting annular guide rail 906 and the lower die elastic pressure head lifting annular guide rail 806;

the clamped product can rotate towards the main parting cutter 11 along with the rotation of the parting turntable 3, the upper die pressing mechanism turntable 902 and the lower die pressing mechanism turntable 802 drive the upper die elastic pressure head follower wheel 905 and the lower die elastic pressure head follower wheel 805 to rotate towards the starting ends of the low track sections of the upper die elastic pressure head lifting annular guide rail 906 and the lower die elastic pressure head lifting annular guide rail 806 through the upper die elastic pressure head guide sleeve and the lower die elastic pressure head guide sleeve respectively, when the parting turntable 3 rotates the product to the main parting cutter 11, the upper die elastic pressure head follower wheel 905 and the lower die elastic pressure head follower wheel 805 will gradually follow the upper die elastic pressure head lifting annular guide rail 906 and the lower die elastic pressure head lifting annular guide rail 806 to respectively open a gap with the thickness of the parting knife at the parting position of the product by the upper die elastic pressure head 903 and the lower die elastic pressure head 803, but the whole product is clamped by the upper die elastic pressure head 903 and the lower die elastic pressure head 803;

when the mold splitting turntable 3 drives the product to pass through the main mold splitting cutter 11 and the auxiliary mold splitting cutter 12, the upper mold and the lower mold of the product are cut, the upper mold pressing mechanism turntable 902 and the lower mold pressing mechanism turntable 802 respectively drive the upper mold elastic pressure head follower wheel 905 and the lower mold elastic pressure head follower wheel 805 to rotate towards the end point end of the high track section of the upper mold elastic pressure head lifting annular guide rail 906 and the high track section of the lower mold elastic pressure head lifting annular guide rail 806 through the upper mold elastic pressure head guide sleeve and the lower mold elastic pressure head guide sleeve, the upper mold elastic pressure head follower wheel 905 and the lower mold elastic pressure head follower wheel 805 can slowly and respectively cause the upper mold elastic pressure head 903 and the lower mold elastic pressure head 803 to gradually separate the upper mold and the lower mold of the product along with the upper mold elastic pressure head lifting annular guide rail 906 and the lower mold elastic pressure head lifting annular guide rail 806, at the moment, the upper mold of the product is adsorbed at the lower end of the lower mold elastic pressure head 803;

with the continuous rotation of the mold splitting turntable 3, the upper mold elastic pressure head 903 sends the upper product mold into the upper mold discharging track 13, and the upper product mold finally falls into the upper mold blanking box 24, the lower mold elastic pressure head 803 rotates the lower product mold to the lower mold limiting block 14, and the lower mold limiting block 14 can block the lower product mold, so that the lower product mold can be conveniently and smoothly rotated out to the next procedure by the discharging turntable.
