[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0024] Please refer to Figures 1-5 , an electric demolding device, including a demolding box 1, a box door 2 and a control console 3. The box door 2 is arranged on the front of the demolding box 1. The box door 2 can close the front of the demolding box 1. When the box door 2 is opened, it is convenient for the staff to repair the components inside the demolding box 1. The control console 3 is arranged on the top of the demolding box 1. The control console 3 can control the operation of the whole device. A demolding mechanism is arranged inside the demolding box 1, and an adjusting mechanism is arranged on the top of the demolding box 1.

[0025] Specifically, the demolding mechanism includes a driving motor 111, a connecting rod 112, a threaded sleeve 113, a threaded rod 114 and a push plate 115. The driving motor 111 is arranged on the inner bottom wall of the demolding box 1. One end of the connecting rod 112 is fixedly connected to the output end of the driving motor 111, and the other end of the connecting rod 112 is fixedly connected to the bottom of the threaded sleeve 113 by screws. The top of the threaded sleeve 113 is threadedly connected to one end of the threaded rod 114. The push plate 115 is welded to the top of the threaded rod 114. The outer surface of the threaded rod 114 is slidably connected to the plate body at the top of the demolding box 1. A notch adapted to the threaded rod 114 is formed in the plate body at the top of the demolding box 1. The outer surface of the threaded sleeve 113 is rotatably connected to a fixing plate 116, and the fixing plate 116 is fixedly connected to the inner side of the demolding box 1 by screws.

[0026] Through the above technical solution, after the mold is placed on the top of the demolding box 1, the driving motor 111 is started. The driving motor 111 drives the threaded sleeve 113 to rotate through the connecting rod 112. When the threaded sleeve 113 rotates, it drives the threaded rod 114 to move up and down. When the threaded rod 114 drives the push plate 115 to move upward, the threaded rod 114 drives the push plate 115 to conveniently eject the specimen in the mold, so that the specimen and the mold can be conveniently separated, making the electric demolding device convenient to use; the fixing plate 116 is connected to the threaded sleeve 113 through a bearing, making the rotation of the threaded sleeve 113 more stable.

[0027] Specifically, the adjusting mechanism includes a hydraulic cylinder 211, a support column 212, a top plate 213, a fixing block 214, a support rod 215, and a bottom plate 216. Four groups of hydraulic cylinders 211 are arranged on the inner bottom wall of the demolding box 1. One end of the support column 212 is fixedly connected to the output end of the hydraulic cylinder 211, and the other end of the support column 212 is welded to the bottom of the top plate 213. The support column 212 slides inside the plate body at the top of the demolding box 1. Four groups of fixing blocks 214 are welded at symmetrical positions on the top of the demolding box 1. Both ends of the support rod 215 are welded to the inner sides of two groups of fixing blocks 214 in the vertical direction. Both sides of the bottom plate 216 are slidably connected to the outer surface of the support rod 215. Circular notches are provided at the tops of the top plate 213 and the bottom plate 216. A pulling frame 217 is fixedly connected to the front of the bottom plate 216 by screws.

[0028] Through the above technical solution, during demolding, the worker pulls the pulling frame 217. The pulling frame 217 drives the bottom plate 216 to move on the outer surface of the support rod 215, and the bottom plate 216 slides outwards, facilitating the worker to place the mold into the notch at the top of the bottom plate 216. After the mold is placed, the worker pushes the bottom plate 216 to move below the top plate 213 through the pulling frame 217, aligning the notches at the tops of the top plate 213 and the bottom plate 216 with the push plate 115. At the same time, the hydraulic cylinder 211 is started. The hydraulic cylinder 211 drives the top plate 213 to move downward through the support column 212. When the top plate 213 moves downward, it presses against the top of the mold. When the push plate 115 moves upward, the specimen can be ejected from the mold, enabling the electric demolding device to conveniently demold specimens of different heights.

[0029] During use, by adjusting the extension length of the threaded rod 114, when the threaded rod 114 drives the push plate 115 to move upward, the threaded rod 114 can conveniently drive the push plate 115 to eject the specimen in the mold, enabling the specimen to be conveniently separated from the mold and facilitating the use of the electric demolding device.

[0030] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
