[0054] Working principle:

[0055] The operation process of the automatic demolding device is as follows:

[0056] 1) Manual operation one

[0057] The product 001 is manually lifted to the automatic demolding device, the distance between the two sets of product fixing mechanisms 106 is adjusted, and the product 001 is clamped on the product fixing mechanisms 106 by contacting the product lifting tool 006 respectively; the positions of the upper mold demolding mechanism 104 and the lower mold demolding mechanism 105 are adjusted to clamp the outer peripheral flange plates of the upper mold 003 and the lower mold 004 into the upper mold clamping seat 1041 and the lower mold clamping seat 1051 respectively, lock the product fixing mechanism 106, and fix the product 001 to the demolding platform 103. The connecting bolt 005 is manually removed.

[0058] 2) Demolding the upper mold

[0059] The operator removes, starts the turnover driving part 1022, and turns the turnover platform 1023 and the demolding platform 103 together by ninety degrees to make the product 001 vertical, and the upper mold demolding mechanism 104 moves upward to slowly pull out the upper mold 003, and stops after reaching the position. The turnover driving part 1022 turns the product 001 into horizontal again.

[0060] 3) Manual operation two

[0061] The operator enters the working space, removes the upper mold 003 from the equipment, and installs the demolding tool 4 on the inner mold 002, and then the operator removes.

[0062] 4) Pulling the inner mold and demolding the lower mold

[0063] The operator starts the automatic demolding device, which flips by 90 degrees, again making the product 001 vertical. The moving frame 1072 is translated to position, and the hanging block 1075 is coaxial with the demolding tool 4. The demolding platform 103 carries the product 001 downward, the hanging block 1075 contacts the demolding tool 4, and the inner mold 002 is hung. The product 001 continues to move downward according to the program, and finally the inner mold 002 is separated from the product 001. The auxiliary clamping jaw A 1078 on the moving frame 1072 clamps and positions the inner mold 002. The moving frame 1072 is translated back to the original position, and the inner mold transfer component 3 comes over to grab the inner mold 002 and place it on the inner mold collection frame 2. At the same time that the inner mold 002 is pulled out, the lower mold demolding mechanism 105 is started, and the lower mold 004 is pulled out from the product 001. The demolding platform 103 carries the product 001 back to the original position, the automatic demolding device flips the product 001 back to the horizontal state, and the equipment is stopped.

[0064] 5) Manual operation three

[0065] The operator enters the workshop, manually removes the lower mold 004, loosens the clamp 1062, and horizontally hoists and removes the demolded product 001. This completes the demolding process for one product 001, and the next product 001 is demolded.
