[0099] The turnover part 400 is arranged on a fixing frame 800. The turnover part 400 comprises a turnover plate 410 configured to be turned over to the lower side of the lower mold assembly 100 to receive the ice block 10 falling from the lower mold assembly 100.

[0100] During ice making, with reference to Figure 5 and Figure 6 The upper mold assembly 200 is combined with the lower mold assembly 100, and the turnover plate 410 is located at the back side of the upper mold assembly 200.

[0101] After ice making is completed, with reference to Figure 7 The upper mold assembly 200 moves upward to be separated from the lower mold assembly 100. At this time, the ice block 10 moves synchronously with the upper mold assembly 200, the turnover plate 410 is turned over to the lower side of the upper mold assembly 200, that is, the turnover plate 410 is located in the gap between the upper mold assembly 200 and the lower mold assembly 100, the turnover plate 410 assumes a downward inclined posture, the second heating part works, the ice block 10 is separated from the upper mold body 220, the ice block 10 falls onto the turnover plate 410, and moves along the turnover plate 410 to the external ice storage device.

[0102] The lower mold assembly 100 is fixedly immovable, the upper mold assembly 200 is lifted and lowered under the action of the lifting driving assembly 300, the movement of the falling ice block 10 is received and guided by the configured turnover part 400, and the driving of the lower mold assembly 100 is cancelled, thereby having a reliable structure and reducing cost.

[0103] In some embodiments of the present application, referring to Figure 17 , the overturning part 400 further comprises a second driving motor 420 fixedly arranged on the fixed frame 800, and the overturning plate 410 is fixedly connected with a power shaft of the second driving motor 420, and the overturning plate 410 is rotationally connected with the fixed frame 800.

[0104] The second driving motor 420 drives the overturning plate 410 to rotate. The second driving motor 420 directly drives the overturning plate 410 to rotate, and the structure is reliable.

[0105] In some embodiments of the present application, referring to Figures 18 to 20 , the overturning plate 410 comprises a first sub-overturning plate 412 and a second sub-overturning plate 413, the first sub-overturning plate 412 extends obliquely upward from the top of the second sub-overturning plate 413, and the second sub-overturning plate 413 is rotationally connected with the fixed frame 800.

[0107] When the upper die assembly 200 moves upward, referring to Figure 19 and Figure 20 , as the upper die assembly 200 continuously rises, the upper die assembly 200 continuously approaches the first sub-overturning plate 412, until the upper die assembly 200 pushes the first sub-overturning plate 412, so that the second sub-overturning plate 413 is overturned to below the upper die assembly 200.

[0108] When the upper die assembly 200 moves downward, the upper die assembly 200 is separated from the first sub-overturning plate 412, and as the upper die assembly 200 continuously descends, the upper die assembly 200 will contact the second sub-overturning plate 413 and push the second sub-overturning plate 413 to reset.

[0109] The overturning plate 410 does not need to be configured with a driving mechanism, and the overturning action of the second sub-overturning plate 413 is realized by using the abutting action between the first sub-overturning plate 412 and the second sub-overturning plate 413 when the upper die assembly 200 moves up and down, which is low in cost and reliable in structure.

[0110] In some embodiments of the present application, the end of the first sub-overturning plate 412 is provided with a bending part 414, which improves the abutting reliability between the upper die assembly 200 and the first sub-overturning plate 412.

[0111] In some embodiments of the present application, referring to Figure 21 and Figure 22, a gear 430 is provided on the flip plate 410. An extension arm 211 extending downward is provided on the upper mold assembly 200, and a rack 212 is provided on the extension arm 211. For example, an extension arm 211 is provided on the upper mold fixing base 210, and a rack 212 is provided at the lower end of the extension arm 211.

[0113] When the upper mold assembly 200 moves upward, refer to Figure 21 As the upper mold assembly 200 continues to rise, until the rack 212 engages with the gear 430, the flip plate 410 is driven to flip to the bottom of the upper mold assembly 200.

[0114] When the upper mold assembly 200 moves downward, as the upper mold assembly 200 continues to descend, the rack 212 separates from the gear 430, and the lower end of the extension arm 211 contacts the flip plate 410, pushing the flip plate 410 to reset.

[0115] The flip plate 410 does not need to be configured with a driving mechanism. The flip plate 410 can be flipped by utilizing the cooperation between the gear 430 and the rack 212 and the lifting action of the upper mold assembly 200. This has low cost and reliable structure.

[0116] In some embodiments of this application, refer to Figure 23 and Figure 24 The flip plate 410 is provided with a rotating shaft 450, which is rotatably connected to the fixed frame 800.

The fixed frame 800 also includes a back plate 830. Both ends of the rotating shaft 450 are rotatably connected to the side beams 820 of the fixed frame 800, and the other end of the torsion spring 440 abuts against the back plate 830.

[0117] The upper mold assembly 200 is provided with an extension arm 211 extending downward.

[0118] When the upper mold assembly 200 and the lower mold assembly 100 are docked, refer to Figure 23 , the extension arm 211 abuts against the flip plate 410 so that the flip plate 410 is located on the rear side of the upper mold assembly 200, and the torsion spring 440 is in a compressed state.

[0119] When the upper mold assembly 200 moves upward, refer to Figure 24 As the upper mold assembly 200 continues to rise, the extension arm 211 separates from the flip plate 410 , and the flip plate 410 flips to the bottom of the upper mold assembly 200 under the action of the torsion spring 440 .

[0120] When the upper mold assembly 200 moves downward, the lower end of the extension arm 211 contacts the turnover plate 410 and pushes the turnover plate 410 to reset as the upper mold assembly 200 continuously descends.

[0121] The turnover plate 410 does not need to be configured with a driving mechanism, and the turnover action of the turnover plate 410 is realized by using the torsional spring 440 in combination with the lifting action of the upper mold assembly 200, which is low in cost and reliable in structure.

[0122] In some embodiments of the present application, referring to Figure 7 and Figure 17 , the turnover plate 410 is provided with a let-in opening 411, and when the turnover plate 410 turns over, the guide part 850 is located in the let-in opening 411 to not interfere with the turnover movement of the turnover plate 410.
