[0032] In this embodiment: the positioning mechanism 200 includes a positioning component for clamping and positioning the mold frame, and an adjusting component for adjusting the clamping force of the mold frame;

[0033] The positioning assembly includes two moving seats 203 slidably installed inside the second slide rails on both sides, and are symmetrically arranged front to back.

[0034] The adjustment component includes a sliding plate 209 slidably mounted on the side wall of the connecting column, the sliding plate 209 is connected to the connecting column by a spring, a plurality of protrusions 211 are evenly distributed on the side wall of the sliding plate 209 in the vertical direction, a connecting plate is arranged on the side wall of the movable seat 203, an electric push rod 213 is arranged on the connecting plate, an insert block 210 is arranged at the telescopic end of the electric push rod 213, the insert block 210 is slidably connected to the sliding box 212, the insert block 210 and the protrusion 211 are both arc-shaped at one end close to each other, and are both flat at one end away from each other, a second oil chamber 207 is formed between the second piston plate 208 away from the clamping plate 204 and the inner wall of the sliding box 212, and the second piston plate 208 is connected to the inner wall of the second oil chamber 207 by a spring A first oil chamber 205 is formed between the first piston plate 206 and the inner wall of the fixing seat 201, and the first piston plate 206 is connected to the inner wall of the first oil chamber 205 by a spring. An oil pipe is arranged between the first oil chamber 205 and the second oil chamber 207, and the oil pipe is retractable. The mold frames of different widths are clamped by adjusting components. When the concrete inside the mold frame is vibrated and stirred, the mold frame itself will cause a certain amount of shaking. The shaking of the mold frame is then detected by adjusting components. The greater the shaking amplitude of the mold frame, the greater the clamping force applied by the positioning component to the two sides of the mold frame, thereby reducing the shaking of the mold frame, greatly enhancing the clamping effect of the mold frame, and improving the positioning effect of the mold frame.

[0035] Working principle: First, the mold frame is placed on the bottom frame 100, and the second cylinders 306 on the front and rear sides push the rollers 307 to move upward to support the mold frame, facilitate the movement of the mold frame, and slowly push the mold frame backward to a preset position. Then, the kinetic energy of the second motor 304 drives the second lead screw 305 to rotate, driving the moving seats 203 on the front and rear sides to move toward each other, driving the clamping plates 204 to move, and adjusting the spacing between the clamping plates 204 on the front and rear sides to adapt to mold frames of different lengths.

[0036] The kinetic energy of the first motor 301 drives the first lead screw 303 to rotate, drives the sliding seats 302 on both sides to move toward each other, drives the clamping plates 204 on both sides to clamp and fix the side walls of the mold frame, and then the second cylinders 306 on the front and rear sides push the top plate 308 to move upward, and at the same time, the second cylinders 306 drive the roller 307 to retract downward into the sliding frame, thereby reducing the sliding of the bottom of the mold frame and supporting the bottom of the mold frame;

[0037] When the concrete inside the mold frame is vibrating and stirring, the mold frame itself will be driven to vibrate to a certain extent, causing the mold frame to shake to a certain extent. When the mold frame shakes, the rollers 202 on both sides are pressed to cause the rollers 202 to move into the first oil chamber 205, driving the first piston plate 206 to move into the first oil chamber 205, and the internal hydraulic oil is squeezed into the second oil chamber 207 through the oil pipe, thereby pushing the second piston plate 208 to move toward the mold frame, driving the connecting column and the clamping plate 204 to move toward the mold frame. When the connecting column moves, the multiple protrusions 211 on the side wall will slide with the plug block 210, and the plug block 210 will slide with the protrusion 211. , so that its protrusion 211 drives the sliding plate 209 to form a unidirectional movement, drives the connecting column to move unidirectionally, thereby drives the clamping plate 204 to move unidirectionally, and increases the clamping force on the side wall of the mold frame, so that when the mold frame shakes more, the clamping force applied by the clamping plates 204 arranged on both sides to the side wall of the mold frame is greater, thereby reducing the shaking of the mold frame, greatly enhancing the clamping effect of the mold frame, and improving the positioning effect of the mold frame. When it is necessary to reset the clamping plate 204, the electric push rod 213 pulls the plug block 210 to move to the side away from the protrusion 211, and disengages from the limit fit with the protrusion 211, so that the clamping plate 204 is reset by the action of the spring.

[0038] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
