Description

Technical Field

[0001] This utility model belongs to the field of refractory brick mold technology, specifically a quick positioning and installation device for a pressure upper mold for refractory brick forming. Background Technology

[0002] Refractory bricks are a key industrial material with excellent high-temperature resistance and good resistance to chemical corrosion. They are usually made from refractory raw materials such as alumina, silica, and magnesia through high-temperature firing. They are widely used in the lining of high-temperature industrial kilns and reaction equipment in steel, cement, glass, ceramics and other industries. They can effectively resist thermal shock, mechanical wear and chemical corrosion in high-temperature environments, ensuring long-term stable operation of equipment and extending its service life.

[0003] In the production process of refractory bricks, the forming stage generally adopts a pressure forming process. First, the raw material powder is poured into the cavity of the lower mold. Then, the upper mold is driven downward by the pressure equipment. By continuously applying a specific pressure, the extrusion molding is completed, so that the loose powder is tightly bound into a green body with a certain strength and shape. In actual production, as the brick shape changes, the corresponding brick mold is replaced at any time to match the production requirements. The upper mold is installed by bolt fixing. That is, the connecting part of the upper mold is aligned with the reserved installation groove on the base, and then multiple sets of bolts are inserted into the screw holes in the groove for tightening. When replacing this installation method, the bolts must be loosened one by one. Bolts that are exposed to high temperature environment for a long time are prone to rust and seizing. Disassembly often requires repeated prying with tools such as wrenches and hammers, which is time-consuming, laborious and very troublesome. Therefore, it needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems. This invention provides a quick positioning and installation device for the upper mold of refractory brick forming pressure, which has the advantage of quick positioning and installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick positioning and installation device for a pressure upper mold for refractory brick forming, comprising a base, with mounting grooves provided inside the left and right ends of the base, an upper mold movably connected to the bottom of the base, connecting plates fixedly connected to the left and right sides of the top of the upper mold, the top of the connecting plates extending above the base and movably connected to the inner surface of the mounting grooves, side plates fixedly installed on the front and rear sides of the top of the base, a support plate fixedly connected between the side plates, a motor fixedly connected to the top of the support plate, a rotating shaft fixedly connected to the other end of the motor output shaft, a rotating rod fixedly sleeved on the outer surface of the rotating shaft, hinge rods hinged to the left and right ends of the rotating rods, a moving plate hinged to the other end of the hinge rods, the outer surface of the moving plate movably connected to the inner wall of the side plate, an insert fixedly connected to the outer side of the moving plate, the other end of the insert penetrating the connecting plate and extending to the outside of the connecting plate and movably sleeved to the inner wall of the connecting plate.

[0006] As a preferred embodiment of this utility model, a top plate is fixedly connected to the top of the side plate, and a first limiting rod is fixedly installed inside the inner side of the side plate, with the outer surface of the first limiting rod movably sleeved with the inner wall of the movable plate.

[0007] As a preferred embodiment of this utility model, fixing plates are fixedly installed on both the left and right sides of the top of the base, and the front and rear ends of the fixing plates are fixedly connected to the inner surface of the side plates.

[0008] As a preferred embodiment of this utility model, push plates are movably installed on both the left and right sides of the top of the base, the outer surface of the push plate is movably connected to the outer surface of the connecting plate, and the outer surface of the push plate is movably connected to the inner wall of the side plate.

[0009] As a preferred embodiment of this utility model, the push plate has a second limiting rod movably sleeved inside both the front and rear ends, and the left and right ends of the second limiting rod are fixedly connected to the inner wall of the side plate.

[0010] As a preferred embodiment of this utility model, a double-threaded rod is movably sleeved inside the side plate, and a rotating block is fixedly sleeved on the front side of the outer surface of the double-threaded rod.

[0011] As a preferred embodiment of this utility model, the front and rear sides of the outer surface of the double threaded rod are threaded with movable blocks, the bottom of the movable blocks is movably connected to the bottom of the base, and the interior of the left and right sides of the movable blocks is hinged with push-pull rods, the other end of the push-pull rods being hinged to the top of the push plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting up a connecting plate, a motor, a rotating rod, and insert blocks, allows for easy replacement of the upper mold. Starting the motor causes the rotating shaft to rotate, which in turn causes the hinge rod to move towards the two insert blocks via the moving plate, disengaging them from the connecting plate and releasing the upper mold from its fixing position. When installing the upper mold at the bottom of the base, simply insert the connecting plate into the base, start the motor to reverse the rotating shaft, and the insert blocks will then be inserted into the connecting plate to fix the upper mold, making it convenient for operators.

[0013] 2. This utility model, by setting a push plate, a double threaded rod, a rotating block and a push-pull rod, when the insert block is inserted into the interior of the connecting plate, the rotating block is rotated, which causes the double threaded rod to drive the two moving blocks to move in opposite directions. This push-pull rod pushes the push plate to contact the outer surface of the connecting plate, thereby pushing the connecting plate to move until the two connecting plates contact the two push plates respectively. This allows the upper mold to be centered and positioned by the connecting plate. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 5 As shown, this utility model provides a quick positioning and installation device for a pressure upper mold for refractory brick forming. It includes a base 1, with mounting grooves 2 opened inside both the left and right ends of the base 1. An upper mold 3 is movably connected to the bottom of the base 1. Connecting plates 4 are fixedly connected to the left and right sides of the top of the upper mold 3. The top of the connecting plates 4 extends to the top of the base 1 and is movably connected to the inner surface of the mounting grooves 2. Side plates 12 are fixedly installed on the front and rear sides of the top of the base 1. A support plate 5 is fixedly connected between the side plates 12. A motor 6 is fixedly connected to the top of the support plate 5. A rotating shaft 7 is fixedly connected to the other end of the output shaft of the motor 6. A rotating rod 8 is fixedly sleeved on the outer surface of the rotating shaft 7. A hinge rod 9 is hinged to both the left and right ends of the rotating rod 8. A moving plate 10 is hinged to the other end of the hinge rod 9. The outer surface of the moving plate 10 is movably connected to the inner wall of the side plate 12. An insert block 11 is fixedly connected to the outer side of the moving plate 10. The other end of the insert block 11 passes through the connecting plate 4 and extends to the outside of the connecting plate 4 and is movably sleeved with the inner wall of the connecting plate 4.

[0018] When the insert 11 is inserted into the interior of the connecting plate 4, it can fix the upper mold 3, allowing the upper mold 3 to be installed at the bottom of the base 1. When the upper mold 3 needs to be replaced, the motor 6 can be started, causing the rotating shaft 7 to drive the rotating rod 8 to rotate, which in turn causes the hinge rod 9 to drive the two moving plates 10 to move in opposite directions, thereby causing the insert 11 to move inward and disengage from the interior of the connecting plate 4, thus releasing the fixing effect on the upper mold 3. At this time, the operator can replace the upper mold 3.

[0019] The top of the side plate 12 is fixedly connected to the top plate 13, and the inner side of the side plate 12 is fixedly installed with a first limiting rod 14. The outer surface of the first limiting rod 14 is movably sleeved with the inner wall of the movable plate 10.

[0020] When the movable plate 10 moves, it will move along the outer surface of the first limiting rod 14, thereby limiting the movable plate 10 and making the movable plate 10 move more stably from left to right.

[0021] Among them, fixing plates 15 are fixedly installed on the left and right sides of the top of the base 1, and the front and rear ends of the fixing plates 15 are fixedly connected to the inner surface of the side plate 12.

[0022] There are two fixing plates 15, and the two fixing plates 15 are the same size.

[0023] Push plates 16 are movably installed on both the left and right sides of the top of the base 1. The outer surface of the push plate 16 is movably connected to the outer surface of the connecting plate 4, and the outer surface of the push plate 16 is movably connected to the inner wall of the side plate 12.

[0024] When the two push plates 16 move in opposite directions, they can push the connecting plate 4 to move, thereby enabling the upper mold 3 to be centered and positioned through the connecting plate 4.

[0025] The push plate 16 has a second limiting rod 17 movably sleeved inside both the front and rear ends, and the left and right ends of the second limiting rod 17 are fixedly connected to the inner wall of the side plate 12.

[0026] By setting a second limiting rod 17, the second limiting rod 17 can limit the push plate 16, so that the push plate 16 can move along the outer surface of the second limiting rod 17.

[0027] The side plate 12 is internally fitted with a double threaded rod 18, and a rotating block 19 is fixedly fitted on the front side of the outer surface of the double threaded rod 18.

[0028] The operator can rotate the rotating block 19 to drive the double threaded rod 18 to rotate. The threads on the front and back sides of the outer surface of the double threaded rod 18 are in opposite directions.

[0029] Among them, the front and rear sides of the outer surface of the double threaded rod 18 are threaded with moving blocks 20. The bottom of the moving blocks 20 is movably connected to the bottom of the base 1. The interior of the left and right sides of the moving blocks 20 is hinged with push-pull rods 21. The other end of the push-pull rods 21 is hinged to the top of the push plate 16.

[0030] When the double threaded rod 18 rotates, it will drive the two moving blocks 20 to move towards each other, thereby pushing the push plate 16 to move through the push-pull rod 21, so that the push plate 16 contacts the outer surface of the connecting plate 4.

[0031] Working principle and usage process of this utility model: When the operator needs to replace the upper mold 3, first, start the motor 6 to make the rotating shaft 7 drive the rotating rod 8 to rotate. This allows the moving plate 10 to move towards each other under the limiting action of the first limiting rod 14 through the hinge rod 9. This causes the insert block 11 to disengage from the interior of the connecting plate 4, thereby releasing the fixing effect on the upper mold 3. At this time, the operator can remove the upper mold 3. When installing, insert the corresponding connecting plate 4 at the top of the upper mold 3 into the interior of the base 1 through the mounting groove 2. Then, start the motor 6 to make the rotating shaft 7 reverse, so that the insert block 11 is inserted into the interior of the connecting plate 4, thereby completing the installation of the upper mold 3.

[0032] After the upper mold 3 is installed, the rotating block 19 is rotated to cause the double threaded rod 18 to drive the two moving blocks 20 to move towards each other. This causes the push plate 16 to move through the push-pull rod 21. When one of the push plates 16 contacts the outer surface of one of the connecting plates 4, it can push the connecting plate 4 to move until the two push plates 16 contact the two connecting plates 4 respectively. At this time, the upper mold 3 will be centered and positioned.
