[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model embodiment provides a concrete test block fabrication device, such as... Figure 1-2 As shown, the device includes a base 1 and a mold 3 positioned above the base 1. A bottom plate 4, which can move up and down, is slidably fitted inside the mold 3. An ejection mechanism for lifting the bottom plate 4 is provided between the mold 3 and the base 1. The ejection mechanism includes a housing 2, a rotating shaft 8, a U-shaped rod 9, a connecting rod 10, a hinge block 11, a bearing seat 5, a rotating rod 6, and a handle 7. The bottom of the housing 2 is fixedly connected to the base 1, and the top of the housing 2 is fixedly connected to the mold 3. Bearing seats 5 are fixedly connected to both sides of the housing 2. The two ends of the rotating shaft 8 are rotatably connected to the housing 2 through the bearing seats 5. A U-shaped rod 9 is fixedly connected to the rotating shaft 8. A hinge block 11 is fixedly connected to the bottom of the bottom plate 4.
