Description

Technical Field

[0001] The utility model relates to the technical field of cement brick production equipment, in particular to a limiting mold for cement brick production and processing. Background Art

[0002] In the process of cement brick production, a molding device is needed to extrude the raw materials of cement bricks into the required shape of cement bricks, and then perform other operations such as firing for subsequent production:

[0003] During the processing and production of cement bricks, the raw materials of cement bricks are very sticky and there is a lot of residual material on the top of the mold when loading. As a result, the service life of the mold is not long and the mold needs to be replaced frequently. However, the connection of the mold is still fixed by fixing bolts, which makes the subsequent disassembly very complicated and requires additional tools. At the same time, when the punch head is punching the raw materials in the mold, long-term work can easily cause the punch head to shift, which makes the subsequent punching easy to be damaged, affecting the production effect.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: Figure 1-4 As shown, the utility model provides a limit mold for cement brick production and processing, including a gantry 1, a processing mold 11 is installed at the bottom of the gantry 1, a hydraulic cylinder 12 is fixedly installed on the top of the gantry 1, and a punch head 13 is provided at the output end of the bottom of the hydraulic cylinder 12 and directly above the processing mold 11. A first mounting plate 2 is fixedly provided at both ends of the upper surface of the processing mold 11, and a second mounting plate 21 is provided directly above the first mounting plate 2. Two symmetrically distributed mounting grooves 24 are opened on the upper surface of the first mounting plate 2, and a mounting block 22 corresponding to the mounting groove 24 is fixed on the lower surface of the second mounting plate 21. A positioning groove 23 is provided on the mounting block 22, and grooves 25 are provided at both ends of the two mounting grooves 24 inside the first mounting plate 2. A moving block 26 is slidably provided in the groove 25, and a positioning rod 27 is fixed to the side of the moving block 26 facing the adjacent groove 25. A long rod 28 is provided on the outer side wall of the first mounting plate 2, and two thread grooves 29 are symmetrically arranged with two threads at both ends of the long rod 28. A connecting block 261 is fixed on the side of the moving block 26 close to the long rod 28, and the connecting block 261 is threaded on the thread groove 29. The electric rod 14 is installed at the middle end of the upper surface of the second mounting plate 21.

[0018] A protective plate 3 is fixedly installed on one side of the first mounting plate 2 close to the long rod 28. The long rod 28 and the connecting block 261 are both located inside the protective plate 3. The protective plate 3 can protect the long rod 28 and the connecting block 261 to prevent the raw materials from adhering to the inside of the production device and affecting its use when the production device is working.

[0019] The cam 33 is fixed to one end of the long rod 28, and the end of the long rod 28 away from the long rod 28 passes through the protective plate 3 and is fixed with a rotating wheel 32. The outer surface of the rotating wheel 32 is fixed with an anti-slip strip. The rotating wheel 32 can facilitate the staff to drive the long rod 28 to rotate, thereby improving the convenience of operation; a clamping block 33 is provided on the outside of the rotating rod 31, and a clamping plate 34 is fixed on the side wall of the first mounting plate 2 close to the clamping block 33, and the clamping block 33 can be clamped in the clamping plate 34; the outer wall of the rotating rod 31 is fixed with a ring-shaped long strip 35, and the clamping block 33 is movably inserted on the long strip 35. The long strip 35 is set so that the clamping block 33 can drive the rotating rod 31 to rotate together. At the same time, the clamping block 33 can move on the rotating rod 31 to disengage from the clamping plate 34, ensuring that the rotating rod 31 can rotate freely.

[0020] A vertically arranged limit rod 15 is fixed at both ends of the upper surface of the second mounting plate 21, and a limit block 16 is fixed on the side wall of the top of the punching head 13 near the limit rod 15. The limit block 16 movably passes through the limit rod 15. The set limit block 16 and the limit rod 15 can ensure that the punching head 13 and the processing mold 11 are stably maintained in a vertical state to prevent the bottom from shifting during stamping, resulting in abnormal stamping; a limit strip 17 is fixed on the outside of the limit rod 15, and the limit strip 17 can pass through the limit block 16 together with the limit rod 15. The set limit strip 17 can further increase the stability of the punching head 13 when it moves up and down.

[0021] Working principle: When the processing mold 11 needs to be replaced during use, the staff can first pull the clamping block 33, and then directly rotate the rotating wheel 32. The rotating wheel 32 drives the long rod 28 to rotate through the rotating rod 31. The connecting blocks 261 with threads on the threaded grooves 29 at both ends of the long rod 28 drive the moving block 26 to move backward at the same time, so that the positioning rod 27 on the moving block 26 is disengaged from the positioning groove 23 on the mounting block 22. At this time, the fixation of the second mounting plate 21 will be directly cancelled. Then the staff can control the electric rod 14 to drive the second mounting plate 21 to move upward, and finally separate the first mounting plate 2 and the second mounting plate 21, completing the disassembly of the processing mold 11. After unloading, the new processing mold 11 is placed under the punch head 13, and the electric rod 14 is controlled to move downward so that the mounting block 22 on the second mounting plate 21 is inserted into the mounting groove 24 provided on the first mounting plate 2. Then, the rotating wheel 32 is rotated in the opposite direction, so that the two adjacent moving blocks 26 can move toward each other, so that the positioning rod 27 on the moving block 26 is inserted into the positioning groove 23 in the mounting block 22, completing the final fixation between the first mounting plate 2 and the second mounting plate 21. After the installation is completed, the clamping block 33 is clamped into the clamping plate 34, so that the rotating rod 31 and the long rod 28 are both stopped, preventing the rotating rod 31 from driving the long rod 28 to rotate arbitrarily and causing wire back.

[0022] The limiting block 16 and the limiting rod 15 can ensure that the punch head 13 and the processing die 11 are kept in a stable vertical state, thereby preventing the bottom from shifting during punching and causing abnormal punching.

[0023] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
