[0014] 5 pin, 6 rotating body, 601 rotating head, 602 rotating shaft portion, 7 spiral convex rib, 8 compression spring, 9 fixing plate, 10 driving motor. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions of the present application will be further described and illustrated below in conjunction with the accompanying drawings and embodiments.

[0016] Such as Figure 1As shown in the figure, it is an easy demoulding device for alloy aluminum ingots, including a demoulding table 1. An ejection mechanism is arranged inside the demoulding table 1. The ejection mechanism includes a sleeve body 2 fixed to the bottom of the demoulding table 1. A ejector head 3 is slidably connected inside the sleeve body 2. One end of the ejector head 3 abuts against the lower surface of the demoulding table 1, and the other end is connected with a sliding sleeve 4. Pin shafts 5 are symmetrically inserted through the outer peripheral surface of the sliding sleeve 4. A rotating body 6 is arranged inside the sleeve body 2. Spiral ridges 7 are arranged on the outer peripheral surface of the rotating body 6. The pin shaft head located inside the sliding sleeve 4 abuts against the spiral ridges 7. A compression spring 8 is arranged between the sliding sleeve 4 and the bottom of the sleeve body 2. A fixing plate 9 is arranged at the bottom of the demoulding table 1, and the sleeve body 2 is installed on the upper surface of the fixing plate 9. The rotating body 6 includes a rotating head 601 arranged inside the sliding sleeve 4. The lower end of the rotating head 601 is connected with a rotating shaft portion 602, and the rotating shaft portion 602 is connected with a driving motor 10. The driving motor 10 is installed on the lower surface of the fixing plate 9. One end of the compression spring 8 abuts against the lower end surface of the sliding sleeve 4, and the other end abuts against the inner bottom surface of the sleeve body 2. The sleeve body 2 includes a flange body 201, and an annular cover body 202 is arranged on the neck end surface of the flange body 201.

[0017] During operation, the operator controls the driving motor 10 below the demoulding table 1 to work. The output end of the driving motor 10 drives the rotating body 6 to rotate continuously. During the rotation process, the spiral ridges 7 on the rotating head 601 rotate and abut against the pin shafts 5, so that the rotating body 6 squeezes the pin shafts 5 during rotation, causing the ejector head 3 and the sliding sleeve 4 to move downward, so that the compression spring 8 is in a stressed state. At this time, the ejector head 3 moves downward to the rotating head 601 of the rotating body 6. When the rotating body 6 continues to rotate, the pin shafts 5 are separated from the extrusion of the spiral ridges 7. Due to the reset action of the compression spring 8, the ejector head 3 and the sliding sleeve 4 are quickly ejected, causing the ejector head 3 to strike the bottom surface of the die cavity of the demoulding table 1 to complete the demoulding operation.

[0018] The present invention is not limited to the above embodiments. Based on the technical solutions disclosed in the present invention, those skilled in the art can make some substitutions and deformations to some technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present invention.
