[0027] The quick demoulding assembly 1 includes a bottom support 101 arranged below the lower mold 2, a middle through hole 102 is opened in the middle of the bottom support 101, a fixed cylinder 103 is arranged in the middle through hole 102, a driving disc 104 is arranged in the fixed cylinder 103, a driving screw 105 is passed through the middle thread of the driving disc 104, the top end of the driving screw 105 rotates and passes through the bottom of the fixed cylinder 103, a driving motor 106 is provided at the bottom of the fixed cylinder 103, and the driving shaft of the driving motor 106 is fixedly connected to the end of the driving screw 105.

[0028] A top connecting plate 107 is provided at the top of the driving screw 105, and the top connecting plate 107 is fixedly connected to the driving disc 104 by a push connecting rod 108. Two limit slots 109 are symmetrically provided on both sides of the inner wall of the fixed cylinder 103, and two limit plugs 110 are symmetrically provided on both sides of the driving disc 104. The limit plugs 110 are slidably inserted into the limit slots 109. Two groups of ejection connecting rods 111 are symmetrically provided at the top of the top connecting plate 107. The top ends of the ejection connecting rods 111 extend into the bottom driving channel 5, and the top ends of the ejection connecting rods 111 are connected to groove closing plates 112.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that, fixing rods are evenly arranged around the driving motor 106 , and the fixing rods are all connected to the inner wall of the middle through hole 102 .

[0030] This makes the driving motor 106 more stable when driving the driving screw 105 .

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that, four groups of push connecting rods 108 are provided, and the four groups of push connecting rods 108 are evenly distributed around the driving disc 104 .
