[0025] A cross bar 207 is provided on one side of the clamping block 201 , and the cross bar 207 passes through a sleeve 204 and contacts the sleeve 204 . A hole is provided on the surface of the fixed block 202 , and a rotating block 208 is provided inside the hole, and the rotating block 208 is fixedly connected to a push rod 203 .

[0026] A cross groove 209 is provided on the side surface of the rotating block 208 away from the top rod 203, an LED lamp bead 210 is provided on the outer side of the rotating block 208, a bracket 211 is provided at the bottom of the fixed block 202, a fixing rod 212 is fixedly provided at the bottom of the bracket 211, and the cross-sectional shape of the fixing rod 212 is L-shaped.

[0027] A threaded rod 213 is disposed below the bracket 211 , and a clamping rod 214 is disposed at the top of the threaded rod 213 .

[0028] The clamping rod 214 is in contact with the bracket 211 , and the top surface of the bracket 211 and the top end surface of the clamping rod 214 are arranged horizontally and in a collinear manner.

[0029] When working, the operator first pushes the clamping block 201 with a tool, and the fixed block 202 and the clamping block 201 are pushed forward together with the ejector rod 203, and the ejector rod 203 pushes the casting out. When the operator lifts the tool, the spring 4 rebounds, and the fixed block 202, the clamping block 201, and the ejector rod 203 are bounced up together and restricted by the limit bolt 3. This ejection device can pull the casting out of the mold cavity without affecting the appearance (without adding a draft angle) and without increasing the weight. When the fixed block 202 moves, it will move to one side of the clamping rod 214. If the casting is ejected, the threaded rod 213 is rotated. Since the threaded rod 213 is threadedly connected to the fixed rod 212, the threaded rod 213 can be moved through the fixed rod 212, and the clamping rod 214 is pushed to move upward, and the clamping rod 214 is in contact with the bracket 211, which ensures the upward movement of the clamping rod 214, so that the top end of the clamping rod 214 is located on one side of the fixed block 202, which can block the fixed block 202 and prevent the fixed block 202 and the clamping block 201 from moving during subsequent operations, thereby improving stability and facilitating subsequent operations. The LED lamp bead 210 is turned on. Since the LED lamp bead 210 is located near the rotating block 208, the LED lamp bead 210 allows the operator to quickly find the rotating block 208, thereby improving work efficiency. Then, the tool is combined with the cross slot 209 to rotate the cross slot 209 and the rotating block 208 is rotated at the same time. Since the rotating block 208 is fixedly connected to a push rod 203, the rotating block 208 and a push rod 203 are rotated at the same time. During the rotation of the push rod 203, due to the internal thread The rod 206 is threadedly connected to a push rod 203, and the internal threaded rod 206 is moved by the rotation of the push rod 203. The internal threaded rod 206 is fixedly connected to a sleeve 204, so that the internal threaded rod 206 and the sleeve 204 move at the same time. Because the sleeve 204 is in contact with the cross bar 207, the sleeve 204 moves along the cross bar 207, and the two sleeves 204 are fixedly connected by the connecting rod 205, so that the two sleeves 204 move at the same time, the position of the sleeve 204 is moved, and the casting is ejected again.
