Description

Technical Field

[0001] This utility model relates to the technical field of block forming equipment, and in particular to a block forming machine demolding synchronization device. Background Technology

[0002] A vibration compressor is a machine that uses materials such as sand, gravel, and fly ash with a small amount of cement to produce new types of wall blocks. These new concrete blocks have the characteristics of high strength, easy construction, good wall surface flatness, and fast construction efficiency. The compaction vibratory press includes a vibration system, an upper mold assembly, a main hydraulic cylinder assembly, and a mold frame fixing frame. Concrete raw materials enter the mold frame above the vibration table via guide rails in a material cart. The mold frame is fixed on two side mold frame fixing seats, which can slide up and down via guide column assemblies to accommodate mold frames of different heights. If the heights of the two side mold frame fixing seats are inconsistent, the mold frame will tilt, resulting in inconsistent heights of the vibrated and compressed blocks, leading to poor product quality. Furthermore, concrete raw materials may fall into the vibration system through the gap between the mold frame and the support plate on the vibration table. Existing compaction vibratory presses typically install a synchronization device to ensure stable mold frame height. This synchronization device includes two rotatably mounted synchronous shafts, gears on the two synchronous shafts, and racks meshing with the gears. The racks are connected to the mold frame. When the mold frame is raised or lowered, the synchronous shafts, gears, and racks force the mold frame to maintain a consistent height. However, after long-term operation, the racks in existing synchronization devices may deform under stress, causing them to lose proper meshing with the gears. Additionally, the tight connection between the racks and the mold frame in existing synchronization devices makes adjustment difficult. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a block molding machine demolding synchronization device, which can ensure the meshing of the rack and gear by adjustment.

[0004] The technical solution adopted in this utility model is: a block molding machine demolding synchronization device, including a synchronization gear, a synchronization frame, and two parallel synchronization shafts. Each synchronization shaft has a synchronization gear installed at both ends, and the ends of the two synchronization shafts on the same side are connected by the synchronization frame. The synchronization frame includes an adjustment frame, a connecting rod, a demolding ejector rod, and two parallel racks. The tooth surfaces of the two racks are arranged opposite each other, and the two racks mesh with the synchronization gears on the corresponding synchronization shafts. The connecting rod is connected to the lower end of the two racks, and the demolding ejector rod is connected to the upper end of the two racks. The position of the racks on the connecting rod and the demolding ejector rod is adjustable. Adjusting bolts are installed in pairs at both ends of the adjustment frame, and the adjusting bolts at both ends of the adjustment frame abut against the outer side of the two racks.

[0005] Preferably, the adjusting frame has a first waist hole at both ends, and the rack has a threaded hole at the corresponding position. A first positioning bolt passes through the first waist hole and the threaded hole.

[0006] Preferably, the top two sides of the demolding ejector pin are provided with second waist holes, and the second waist holes are provided with second positioning bolts. The end of the second positioning bolt is threaded into the top of the rack at the corresponding position.

[0007] Preferably, the connecting rod has a third waist hole at each end, and a third positioning bolt is provided in the third waist hole. The end of the third positioning bolt is threaded into the bottom of the rack at the corresponding position.

[0008] Preferably, L-shaped connecting rods are fixed to both ends of the adjusting frame, the adjusting bolt passes through the L-shaped connecting rods, and a locking nut is fitted on the adjusting bolt.

[0009] Preferably, the two synchronous shafts are set at the same height, and the demolding ejector rod and the connecting rod are installed in parallel.

[0010] The beneficial effects of this utility model are as follows: The block forming machine demolding synchronization device of this utility model has an adjustable rack. The position of the rack on the connecting rod and the demolding top rod is adjustable. The position of the rack is adjusted by the adjusting frame so that the rack can abut against the gear after deformation, ensuring stable meshing. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings:

[0015] like Figure 1 and Figure 2As shown, this embodiment provides a block forming machine demolding synchronization device, including a synchronization gear 2, a synchronization frame, and two parallel synchronization shafts 1. The two synchronization shafts 1 are set at the same height, and a synchronization gear 2 is installed at both ends of each synchronization shaft 1. The ends of the two synchronization shafts 1 on the same side are connected by the synchronization frame. The synchronization frame includes an adjustment frame 6, a connecting rod 4, a demolding ejector rod 5, and two parallel racks 3. The tooth surfaces of the two racks 3 are arranged opposite each other, and the two racks 3 respectively mesh with the synchronization gear 2 on the corresponding synchronization shaft 1. The connecting rod 4 is connected to the lower end of the two racks 3, and the demolding ejector rod 5 is connected to the upper end of the two racks 3. The demolding ejector rod 5 and the connecting rod 4 are installed in parallel. The position of the racks 3 on the connecting rod 4 and the demolding ejector rod 5 is adjustable. Adjusting bolts 602 are installed in pairs at both ends of the adjustment frame 6, and the adjusting bolts 602 at both ends of the adjustment frame 6 respectively abut against the outside of the two racks 3.

[0016] In this embodiment, the positions of the two racks 3 can be adjusted. By adjusting the position of the adjusting bolt 602, the position of the racks 3 can be positioned so that the two racks 3 can mesh with the corresponding gears 2, and the position of the racks 3 can be adjusted so that the two racks 3 on the corresponding sides remain parallel.

[0017] In this embodiment, the adjusting frame 6 has first waist holes at both ends, and the rack 3 has threaded holes at corresponding positions. First positioning bolts 7 are inserted into the first waist holes and the threaded holes. The demolding ejector rod 5 has second waist holes on both sides of its top. Second positioning bolts 8 are installed in the second waist holes, and the ends of the second positioning bolts 8 are threadedly engaged with the top of the rack 3 at corresponding positions. The connecting rod 4 has third waist holes at both ends, and third positioning bolts are installed in the third waist holes. The ends of the third positioning bolts are threadedly engaged with the bottom of the rack 3 at corresponding positions. When adjusting the rack 3, firstly, the first positioning bolts 7, second positioning bolts 8, and third positioning bolts are loosened to allow the rack 3 to move. Then, the positions of the adjusting bolt 602 and the rack 3 are adjusted so that the rack 3 and the gear 2 maintain a tight fit, and the adjusting bolt 602 abuts against the rack 3. Finally, the first positioning bolts 7, second positioning bolts 8, and third positioning bolts are tightened to fix the rack 3 and the adjusting frame 6. In this embodiment, the rack 3 is installed in a detachable manner for easy maintenance and replacement.

[0018] In this embodiment, L-shaped connecting rods 601 are fixedly connected to both ends of the adjusting frame 6, and the adjusting bolt 602 passes through the L-shaped connecting rod 601. A locking nut 603 is fitted on the adjusting bolt 602. When adjusting the position of the adjusting bolt 602, the position of the locking nut 603 needs to be adjusted.

[0019] In this embodiment, the block forming machine demolding synchronization device is used by installing the synchronous shaft 1 on the base of the vibration press. The demolding ejector rods 5 at both ends of the synchronous shaft 1 are connected to the corresponding mold frame fixing seats by spot welding. When the mold frame fixing seats are raised and lowered, they drive the demolding ejector rods 5 at both ends of the synchronous shaft 1 to move. The rack 3 drives the gear 2 to rotate, and the corresponding synchronous shaft 1 also rotates. The two synchronous shafts 1 ensure that the mold frame fixing seats on both sides of the vibration press operate synchronously and remain on the same plane.
