While the movable plate 6 moves upward, the support column 207 drives the sliding plate 204 to move upward inside the limiting groove 1 203. At the same time, the mutual cooperation between the oblique guide column 206, the trapezoidal slider 205, the ejector rod 208, the limiting groove 209 and the spring 210 can effectively drive the ejector rod 208 to eject and separate the oil pot mold and the punch 7.

[0031] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] When demoulding, firstly, the upper mold 4 is driven to separate from the punch 7 through the first oil cylinder 3, and then the rotating handle 102 is turned clockwise to drive the long strip 103 on the top of the rotating rod 101 to rotate. When the long strip 103 rotates, the upper connecting rod 106 moves to the right, and the lower connecting rod 106 moves to the left. At this time, the two guide rods 109 are opened by the cooperation of the wedge-shaped rail block 111, and the two guide rods 108 are constrained by the wedge-shaped rail block 111 and open at the same time, so as to demould the circumference of the oil pot mold. When the rotating handle 102 is turned counterclockwise to drive the long strip 103 to rotate, the two guide rods 109 are closed under the elastic action of the spring 112. At the same time, under the action of the wedge-shaped rail block 111, the two guide rods 108 also make a retracting movement, and after retracting, the next oil pot mold is formed, and then the movable plate 6 is driven to move upward by the second oil cylinder 202. While the movable plate 6 moves upward, the sliding plate 204 is driven to move upward inside the limiting groove 203 through the support column 207. At the same time, through the mutual cooperation between the inclined guide column 206, the trapezoidal slider 205, the push rod 208, the limiting groove 209 and the spring 210, the push rod 208 can be effectively driven to eject and separate the oil pot mold from the punch 7, thereby effectively demoulding, ensuring the demoulding quality, which is beneficial to improving the qualified rate of products and saving manufacturing costs.
