The guide vertical plate 27 is symmetrically slidably inserted on both sides of the inner side of the threaded rod 40, and the third rack 28 is fixedly mounted on the side end of the guide vertical plate 27 away from the support frame 39, and the third rack 28 is meshed with the third gear 29.

[0035] The storage cavity 12 is fixedly mounted on the top ends of both sides of the support frame 39, the center plate 16 is threadedly sleeved on the threaded rod 40, and the end of the prefabricated mold 17 close to the center plate 16 is slidably sleeved on the outer side of the support frame 39 away from the threaded rod 40, which can support the prefabricated mold 17 to slide up and down in a straight line.

[0036] The distance between the bottom end of the second plugboard 10 and the top end of the first plugboard 4 is equal to the thickness of the bottom plate 3. The second plugboard 10 and the first plugboard 4 are inclined at 45° on one end surface close to the storage cavity 12. Through grooves adapted to the second plugboard 10 are provided at both ends of the storage cavity 12. The vertical rack 15 is vertically aligned with the side end of the first gear 6 away from the storage cavity 12. When the prefabricated mold 17 moves up and down, it can drive the vertical rack 15 to pass through the first gear 6, and then drive the second gear 8 to rotate.

[0037] A threaded hole is provided in the inner center of the center plate 16 , and the limiting side rod 38 is located outside the vertical rack 15 . The bottom end of the prefabricated mold 17 is hollow, which facilitates the docking of the bottom plate 3 with the interior of the prefabricated mold 17 .

[0038] The precast mold 17 is symmetrically provided with circular holes on the side ends close to the center plate 16, and a cylinder is symmetrically fixedly installed on the inner side of the support top frame 39 away from the outer side of the threaded rod 40. The opposite ends of the first docking key 21 and the second docking key 26 are inclined at 45°, and the top of the first guide plate 18 is arranged in an arc state. When the first docking key 21 and the second docking key 26 are locked and limited, the first guide plate 18 and the limiting side rod 38 can be driven to be misaligned, so as to prevent the limiting cross plate 20 from interfering with the limiting side rod 38 when the precast mold 17 moves downward again.

[0039] The bottom of the opposite end of the limiting side rod 38 is tilted at 45°, and the limiting side rod 38 is vertically aligned with the first guide plate 18. The bottom of both ends of the support base 37 is provided with a card slot adapted to the sliding card key 42, and the positioning protrusion 31 is vertically aligned with the connecting cross plate 24. When the prefabricated mold 17 moves downward to the extreme position, the connecting cross plate 24 can be lifted up by the positioning protrusion 31 to facilitate the misalignment of the first docking key 21 and the second docking key 26.

[0040] The outer ring surface of the base plate 3 fits with the inner ring surface of the prefabricated mold 17. Concave holes that are compatible with the first spring 19 are opened inside the two ends of the prefabricated mold 17. Sliding holes that are compatible with the limiting horizontal plate 20 are opened at the bottom of both ends of the prefabricated mold 17 to prevent the limiting horizontal plate 20 from falling off.

[0041] The working principle of embodiment 1 is as follows: when in use, the bottom plate 3 is first placed into the interior of the storage cavity 12 in sequence. When the first plug-in plate 4 is kept in a normal state, it can be located below the storage cavity 12, so that the first plug-in plate 4 can prevent the bottom plate 3 inside the storage cavity 12 from falling downward. After that, the driving motor 41 is started to drive the threaded rod 40 to rotate, and the center plate 16 is threadedly sleeved on the threaded rod 40, so that the prefabricated mold 17 can be driven to move upward. When the prefabricated mold 17 moves upward, it can drive the first guide plate 18 to pass through the bottom end of the limiting side rod 38. The bottom end of the limiting side rod 38 is tilted at 45 degrees, and the top of the first guide plate 18 is set in an arc state, so that the first guide plate 18 can be lifted to pass through the limiting side rod 38 smoothly. At the same time, when the first guide plate 18 contacts the limiting side rod 38, the first guide plate 18 can drive the limiting cross plate 20 to move toward the inside of the prefabricated mold 17 through the restriction of the limiting side rod 38, so that the first docking key 21 can be driven to pass the second docking key 26. When the first docking key 21 passes the second docking key 26, the elasticity of the second spring 22 will drive the second docking key 26 to move downward to the limit position, so that the second docking key 26 can contact the back of the first docking key 21, so as to prevent the limiting cross plate 20 from moving outward, thereby limiting the cross plate 20 can play a limiting role at the bottom end of the interior of the prefabricated mold 17. Afterwards, when the prefabricated mold 17 continues to move upward, it can drive the vertical rack 15 to pass the first gear 6, so that it can The first gear 6 and the second gear 8 rotate simultaneously, so that the second plug-in plate 10 can move into the interior of the storage cavity 12. The distance between the first plug-in plate 4 and the second plug-in plate 10 is equal to the thickness of the bottom plate 3, and the end surface of the second plug-in plate 10 close to the storage cavity 12 is inclined at 45 degrees, so that when the second plug-in plate 10 moves into the interior of the storage cavity 12, the bottom plate 3 located at the bottom end of the storage cavity 12 can be separated. Moreover, when the second plug-in plate 10 moves into the interior of the storage cavity 12, the second gear 8 can drive the first rack 7 to move toward the end away from the storage cavity 12, so that the first plug-in plate 4 can be moved out from under the bottom plate 3 at the bottom end of the storage cavity 12, so that the bottom plate 3 can accurately fall into the limiting horizontal plate 20 inside the prefabricated mold 17. After the alignment and assembly of the bottom plate 3 and the prefabricated mold 17 are completed, the driving motor 41 can be started to drive the threaded rod 40 to rotate in the opposite direction, causing the prefabricated mold 17 to move downward, so that the vertical rack 15 can move downward on the surface of the first gear 6, thereby driving the second plugging plate 10 to move again to the end away from the storage cavity 12, so that the first plugging plate 4 can again receive the bottom plate 3 at the bottom end of the storage cavity 12 to prevent the bottom plate 3 from falling prematurely. When the prefabricated mold 17 moves downward to the limit position, the connecting cross plate 24 will contact the positioning protrusion 31. Through the limitation of the positioning protrusion 31, the connecting cross plate 24 can move upward, so that the connecting cross plate 24 can drive the second docking key 26 to be misaligned with the first docking key 21. At this time,The elastic force of the first spring 19 can drive the limiting cross plate 20 and the first guide plate 18 to quickly return to the position away from one end of the precast mold 17, so that the limiting cross plate 20 can be withdrawn from the bottom end of the bottom plate 3, releasing the bottom plate 3. After that, the external concrete can be poured into the interior of the precast mold 17, and the bottom plate 3 is located at the inner bottom end of the precast mold 17, so that the precast mold 17 can cooperate with the bottom plate 3 to accommodate the concrete molding. After that, when the concrete is solidified and formed, the driving motor 41 can be started again to drive the driving motor 41 to rotate, so that the precast mold 17 can be driven to move upward, so that the precast mold 17 can be disengaged from the precast part and the bottom plate 3, and when the precast mold 17 moves upward to be misaligned with the precast part, the center plate 16 can be driven to contact the bottom end of the third rack 28, so that the third rack 28 can be driven to move upward, so that the third rack 28 can pass through the third gear 29 and drive the winding wheel 30 to rotate. When the winding wheel 30 rotates, it can drive the connecting rope 32 to pull the sliding card key 4 2 moves toward the end away from the driving motor 41, so that the pushing plate 36 can push the bottom plate 3 and the preformed part to move, thereby facilitating the misalignment of the bottom plate 3 and the bottom end of the prefabricated mold 17, preventing the prefabricated mold 17 from contacting the prefabricated part when it moves downward again. Afterwards, when the prefabricated mold 17 moves downward, it can drive the third rack 28 to pass through the third gear 29 again, so that the winding wheel 30 can rotate in the opposite direction, releasing the connecting rope 32. At this time, the elastic force of the third spring 35 can drive the pushing plate 36 to return to the rear end, so that the connecting rope 32 can pull the pushing plate 36 to move toward the end close to the threaded rod 40. During the movement of the third rack 28, the guide vertical plate 27 is slidably inserted into the interior of the supporting top frame 39, so that the third rack 28 can be ensured to move up and down in a straight line. Moreover, when the winding wheel 30 rotates in the opposite direction, the third gear 29 can drive the third rack 28 to move downward, completing the reset of the third rack 28 and completing the assembly and discharge of the prefabricated mold 17 and the bottom plate 3. Example 2

[0042] On the basis of Example 1, Figure 8 As shown, the support base 37 also includes a hydraulic cylinder 43, a sealing plate 44, a heating cavity 45 and a guide rail 46. The heating cavity 45 is fixedly mounted on both ends of the top of the support base 37. The guide rails 46 are symmetrically fixedly mounted on both ends of the top of the support base 37, and the guide rails 46 are located below the heating cavity 45. The hydraulic cylinder 43 is symmetrically fixedly mounted on the top of the heating cavity 45. The sealing plate 44 is fixedly mounted on the top of the hydraulic cylinder 43. The spacing between the guide rails 46 is the same as the length of the base plate 3. An L-shaped extension frame is fixedly mounted between the sealing plate 44 and the hydraulic cylinder 43. The interior of the heating cavity 45 is set in a hollow state, and through holes are opened on both sides of the heating cavity 45 close to the sealing plate 44. The sealing plate 44 has the same size as the through holes.

[0043] When implementing this embodiment, when the base plate 3 drives the preform to move on the top of the support base 37, the guide rail 46 is consistent with the length of the preform mold 17, so that the base plate 3 can accurately drive the preform to move to the front end. When the base plate 3 drives the preform to enter the interior of the heating cavity 45, the hydraulic cylinder 43 can be started to drive the sealing plate 44 to move downward until the sealing plate 44 seals the interior of the heating cavity 45. At the same time, the heating unit inside the heating cavity 45 can be started to accelerate the drying of the preform inside the heating cavity 45. Afterwards, when the preform is dried, the hydraulic cylinder 43 can be started again to drive the sealing plate 44 to move upward to be misaligned with the top of the heating cavity 45, so that the base plate 3 and the preform can be easily taken out from the interior of the heating cavity 45, completing the accelerated drying of the preform.

[0044] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
