[0001] The utility model relates to the technical field of precast slab production, in particular to a precast slab production mold convenient for demoulding. Background Technique
[0002] As a part of prefabricated buildings, the utilization rate of precast slabs is gradually increasing, and the production scale of precast slabs is also continuously expanding. Precast slabs are formed in corresponding forming molds. After being fixed and formed, the precast slabs need to be disassembled from the molds after being formed. The method of taking out the precast slabs is often to use a crane to hook the reserved hooks on the precast slabs and then pull upward to make the precast slabs脱离 the molds and transfer them to the specified positions. Since the formed precast slabs will adhere to the molds, the demoulding difficulty is relatively large, and local forces are applied to the precast slabs during the demoulding process, which is easy to cause damage to the precast slabs during demoulding.

[0022] Please refer to Figure 1-6 , an embodiment provided by the present utility model: A precast slab production mold that is easy to demold, including
[0023] A prefabricated shell 12, a "U"-shaped frame body 1 is fixedly installed below the prefabricated shell 12 by bolts, and lifting lead screws 2 and slide rods 29 are installed in parallel on both sides of the "U"-shaped frame body 1. The tops of the "U"-shaped frame bodies 1 on both sides of the prefabricated shell 12 are respectively installed with a first lifting motor 3 and a second lifting motor 13. The drive shafts of the first lifting motor 3 and the second lifting motor 13 are respectively connected to the lifting lead screws 2 on both sides of the "U"-shaped frame body 1. The first lifting motor 3 and the second lifting motor 13 are driven synchronously. A movable support plate 17 is arranged inside the "U"-shaped frame body 1 below the prefabricated shell 12, and both ends of the movable support plate 17 are connected to the lifting lead screws 2 and the slide rods 29 through bait blocks 14.
[0024] When the lifting lead screw 2 rotates, under the action of the thread, the movable support plate 17 moves up and down on the lifting lead screw 2 and the slide rod 29 through the bait block 14.
[0025] At the bottom inside the "U"-shaped frame body 1, there is a bottom plate 18. On the top of the bottom plate 18, there is a support groove 15, and the area of the support groove 15 is larger than the area of the movable support plate 17. At the positions corresponding to the prefabrication bins 4 on the top of the movable support plate 17, there are prefabrication grooves 16, and the prefabrication grooves 16 are used to prevent the frame structure required for manufacturing precast slabs.
[0026] The prefabrication bins 4 are evenly arranged inside the prefabrication shell 12, and inside the prefabrication shell 12 between adjacent prefabrication bins 4, there are movable bins 30. The movable bins 30 are communicated with the prefabrication bins 4, and on the side walls of the movable bins 30 facing the prefabrication bins 4, there are movable side plates 31 installed.
[0027] The first cross bar 22 and the second cross bar 26 are arranged in parallel on both sides of the top of the prefabrication shell 12, and at the positions on the top of the prefabrication shell 12 corresponding to the movable bins 30 below the first cross bar 22 and the second cross bar 26, there are openings 27. On the top of the movable side plates 31, there are two driving blocks 19 installed in parallel, and the two driving blocks 19 are respectively connected with the first cross bar 22 and the second cross bar 26.
[0028] Both ends of the first cross bar 22 and the second cross bar 26 extend into the protective housing 10 arranged at both ends of the top of the prefabrication shell 12, and at both ends of the first cross bar 22 and the second cross bar 26, there are pulley one 23 and pulley two 25 fixedly installed. A transmission belt 24 is fixedly connected between the first cross bar 22 and the second cross bar 26. On one side of the protective housing 10, there is a driving motor 11 installed, and the driving shaft of the driving motor 11 is fixedly connected with one end of the second cross bar 26.
[0029] At the positions corresponding to the movable bins 30 on the first cross bar 22 and the second cross bar 26, there are threaded sections 28. The threaded sections 28 are divided into thread one 20 and thread two 21, and the thread directions of the thread one 20 and the thread two 21 are opposite. The driving blocks 19 on the tops of the two movable side plates 31 inside the movable bin 30 are respectively connected with the thread one 20 and the thread two 21.
[0030] The driving motor 11 drives the second cross bar 26 to rotate. The second cross bar 26 drives the first cross bar 22 to rotate by means of the pulley two 25, the transmission belt 24 and the pulley one 23. The thread one 20 and the thread two 21 of the threaded section 28 rotate accordingly. Under the action of the threads, the driving blocks 19 are used to drive the movable side plates 31 to move towards the inside of the movable bin 30, so that the movable side plates 31 are separated from the solidified precast slab.
[0031] In the middle of the top of the prefabrication shell 12, there is a cross beam 8 horizontally installed through a hydraulic rod 6. At the positions corresponding to the prefabrication bins 4 on the bottom of the cross beam 8, there are ejector rods 9 installed, and the other ends of the ejector rods 9 all extend to the tops inside the corresponding prefabrication bins 4 and are fixedly connected with a stripping plate 5. At the middle position on the top of the cross beam 8, there is a vibration motor 7 installed.
[0032] The vibration motor 7 drives the cross beam 8, the top rod 9 and the stripping plate 5 to vibrate, so as to facilitate the separation of the formed prefabricated board from the side wall of the prefabricated bin 4 and to facilitate the stripping plate 5 to extrude the formed prefabricated board downward.

At this time, the movable support plate 17 is in contact with the bottom of the prefabricated shell 12, and the material of the prefabricated panel is injected into the interior of the prefabricated warehouse 4. After the prefabricated panel is solidified and formed, the driving motor 11 is started, and the driving motor 11 drives the cross bar 26 to rotate. The cross bar 26 uses the pulley 25, the transmission belt 24 and the pulley 1 23 to drive the cross bar 1 22 to rotate, and the thread 1 20 and the thread 2 21 of the thread segment 28 rotate accordingly. 19 drives the movable side plate 31 to move toward the inner side of the movable bin 30, so that the movable side plate 31 is separated from the solidified precast plate, and the vibration motor 7 is started. Then, the hydraulic rod 6, the lifting motor 1 3 and the lifting motor 2 13 are started synchronously. The vibration motor 7 drives the cross beam 8, the top rod 9 and the stripping plate 5 to vibrate. The hydraulic rod 6 drives the cross beam 8 to move downward, thereby driving the stripping plate 5 to extrude the formed precast plate downward, so that the precast plate is separated from the precast bin 4. The lifting motor 1 3 and the lifting motor 2 13 drive the two lifting screws 2 to rotate synchronously. Under the action of the thread, the movable support plate 17 moves downward on the lifting screw 2 and the sliding rod 29. Under the dual action of the stripping plate 5 and its own gravity, the precast plate is demoulded as the movable support plate 17 moves out of the precast bin 4.
