[0017] The beneficial effects of the present invention are: a high-performance radiation protection brick preparation device that does not require vibration and effectively solves the problem of material filling of brick molds with uneven ends. The specific implementation method is as follows:

[0018] The operator first starts the lifting rod to drive the push rod plate to raise the lifting rod, so that the lifting rods on the two sets of mold frames slide to the two ends of the horizontal moving groove until the two sets of mold frames are folded and abutted; while the lifting rod moves, the hydraulic column rises to break away from the abutment with the second fixed port and rotates the opposite threaded rod, so that the two sets of moving plates are close to each other and the moving plates are separated from the abutment with the swing rod. Under the thrust of the thrust spring, the sliding plate is separated from the abutment and fixation with the supporting top plate, so that the supporting top plate can squeeze the pushing spring to move downward;

[0019] After that, the lifting rod is lowered to drive the lifting rod to lower. At the same time, the two groups of mold frames squeeze the support top plates to lower, and after falling between the two groups of support boxes, a recess is formed between the two groups of support boxes and the mold frame. The lowering depth of the mold frame between the support boxes can be reduced as appropriate so that the material can meet the needs of supplementing the mold in the mold frame; the two groups of mold frames are filled with pressing materials of mixed radiation protection materials. At the same time, due to the rotation of the opposite threaded rods, the two groups of moving plates are close to each other. Under the interaction of the magnetic blocks, the two groups of oblique pressing blocks are also folded in half along the connection direction of the sliding ball. Until the lifting nail falls into the swing groove and makes the oblique pressing block perpendicular to the original position, the hydraulic column continues to be lowered so that the hydraulic column abuts the second fixed port. After that, the hydraulic column continues to be lowered to push the oblique pressing block to overcome the thrust of the reset spring on the lifting nail and descend, so that the magnetic block of the oblique pressing block squeezes the material in the mold frame to fit the edge of the brick to be formed, thereby realizing the production of the edge of the anti-slip brick;

[0020] After that, the rising hydraulic column is separated from the first fixed opening, and the oblique pressing block is lifted up and separated from the notch between the support box and the mold frame by the thrust of the reset spring on the lifting pin, and then the lifting rod is started to lift the folded mold frame, and the material in it is cut by the cutting line, and then the mold frame is driven to rise away from the top of the support box;

[0021] At this time, the opposite threaded rods are rotated to separate the two groups of moving plates from each other. The ends of the two groups of oblique-mouth pressing blocks are connected by the suction force of the magnetic blocks, and the hydraulic column continues to be extended. When the hydraulic column abuts and slides into the second fixed mouth, the two groups of oblique-mouth pressing blocks are horizontal; at the same time, the abutting swing rod pushes the sliding plate to abut against the supporting top plate that has been restored to its position by the thrust of the pushing spring to complete the support; the lifting rod descends, and the touch plate at the edge of the mold frame touches the arc-shaped expansion block on the supporting top plate in the fixed position, and the two groups of mold frames expand forward until the lifting rod falls into the limiting groove of the limiting plate and is fixed; at this time, a hard product with a mold edge filled and a connecting surface as an inclined surface is formed between the two groups of mold frames. After continuing to add materials until the space between the two groups of mold frames is filled, the hydraulic column is extended to squeeze the oblique-mouth pressing block into the mold frame to complete the production of the protective brick;

[0022] After completion, first lift the mold frame so that the protective bricks fall between the oblique pressing block and the support box and the supporting top plate, then lift the oblique pressing block to take out the protective bricks.

[0023] The equipment has a simple structure and utilizes a folded mold to produce protective bricks with irregular edges, while ensuring that the radiation protection material is evenly arranged in the bricks. It has good practicality and economy, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The descending depth of the mold frame 11 between the support boxes 14 can be reduced as appropriate so that the material can meet the mold in the supplementary mold frame 11. The pressed material of the mixed radiation protection material is filled in the two groups of mold frames 11. At the same time, due to the rotation of the opposite threaded rods 32, the two groups of moving plates 33 are close to each other. Under the interaction of the magnetic tile block 351, the two groups of inclined plates 33 are The mouth pressing block 35 is also folded in half along the connection direction of the sliding ball 342 until the lifting nail 34 falls into the swinging groove 352 and makes the oblique mouth pressing block 35 perpendicular to the original position, and then the hydraulic column 332 continues to descend, so that the hydraulic column 332 abuts against the second fixed mouth 354, and then the hydraulic column 332 continues to descend to push the oblique mouth pressing block 35 to overcome the thrust of the reset spring 341 on the lifting nail 34, so that the magnetic block 351 of the oblique mouth pressing block 35 squeezes the material in the mold frame 11 to fit the edge of the brick to be formed, so that the edge of the anti-slip brick can be made;

[0045] After that, the ascending hydraulic column 332 is disengaged from the first fixed opening 353, and the oblique pressing block 35 is lifted up and disengaged from the notch formed between the support box 14 and the mold frame 11 by the thrust of the return spring 341 on the lifting pin 34, and then the lifting rod 22 is started to lift the folded mold frame 11, and the material therein is cut by the cutting line 241, and then the mold frame 11 is driven to rise and away from the top of the support box 14;
