Description

Technical Field

[0001] The utility model relates to the field of lifting devices, in particular to a mold lifting device. Background Art

[0002] During the artificial stone pressing process, the original crushed stone and powder are added with an organic binder and then transported into a mold. The mold is then transported to the pressing chamber by a mold trolley for further pressing. Once the artificial stone is formed, the mold is then transported out by the mold trolley to achieve the purpose of transporting the artificial stone. After the mold trolley transports the mold to the pressing chamber, the mold hoisting device transfers the mold from the mold trolley to the pressing chamber floor. After the artificial stone is formed by pressing, the mold hoisting device transfers the mold to the mold trolley for transportation out of the pressing chamber, completing the entire continuous pressing process.

[0003] The existing mold lifting device is mounted on the inner wall of the pressing chamber. Specifically, a guide seat is located on the inner wall of the pressing chamber, and a hook and a cylinder are both located on the guide seat. The cylinder drives the hook to slide on the guide seat, thereby achieving the hook's lifting and lowering. A hook is attached to the outer wall of the mold, and the hook is hung on the hook. When the hook is raised or lowered, the mold is raised or lowered. This mold lifting device has a complex structure and occupies a large space. In addition, the hook of the mold lifting device is subjected to torsion, resulting in high friction resistance between the hook and the guide seat, which is prone to wear and has a short service life.

[0029] To make the objectives, technical solutions, and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside, and outside that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model and do not specifically limit the present utility model.

[0030] Refer to Figures 1-5 , the present utility model discloses a mold 200 lifting device installed in a pressing chamber 100. The pressing chamber 100 is provided with a pressing cavity 101, including a lifting mechanism 1, a connecting seat 2 connected to the lifting mechanism 1, and a locking mechanism installed on the connecting seat 2. The lifting mechanism 1 is used to lift and lower the connecting seat 2. The connecting seat 2 is suspended in the pressing cavity 101, and the locking mechanism is used to connect the connecting seat 2 and the mold 200.

[0031] The lifting mechanism 1 is arranged at the top of the pressing chamber 100 to drive the connecting seat 2 to lift and lower within the pressing cavity 101.

[0032] The latch mechanism includes a driving mechanism 5 and a plug-in member 6 which are connected. The driving mechanism 5 drives the plug-in member 6 to connect or disconnect the mold 200 and the connecting seat 2; the lifting mechanism 1 can drive the mold 200 to lift and lower through the connecting seat 2.

[0033] The lifting mechanism of the mold lifting device of the present utility model is installed at the top of the pressing chamber. The lifting mechanism is connected to the connecting seat so that the connecting seat can lift and lower in the pressing cavity, and the mold is fixed to the connecting seat by using the latch mechanism installed on the connecting seat, thereby driving the mold to lift and lower. Compared with the existing lifting device installed on the inner side wall of the pressing chamber, it occupies less space in the pressing cavity, saves space, and will not interfere with the mold trolley. And it eliminates components such as hooks and guide seats, avoiding problems such as large frictional resistance and easy wear. Its structure is simple, cost-saving, and has a long service life.

[0034] Preferably, the lifting mechanism 1 is an oil cylinder, and the driving mechanism 5 is a cylinder, but it is not limited thereto.

[0035] Specifically, as Figure 2 、 4 shown, the connecting seat 2 includes a base portion 21, a lifting portion 22 and a latch portion 23 provided on the base portion 21. The lifting mechanism 1 is connected to the connecting seat 2 through the lifting portion 22, and the latch mechanism is connected to the connecting seat 2 through the latch portion 23. The lifting portion 22 is provided at the top of the base portion 21, and the latch portion 23 is provided at the bottom of the base portion 21. That is to say, the lifting mechanism is connected to the lifting portion, and the mold is connected to the latch portion. The lifting mechanism drives the connecting seat to lift and lower, thereby driving the mold to lift and lower. When the mold does not need to be lifted, the lifting mechanism can lift the connecting seat to the top of the pressing cavity, and at this time, it does not interfere with the mold and the mold trolley. Its structure is simple and reasonable, and it occupies less space.

[0036] Furthermore, the lifting mechanism is connected to the lifting portion 22 through a lifting connection assembly.

[0037] As Figures 1-4 shown, the lifting connection assembly includes a connecting member 3 and a fixing member 4. The connecting member 3 is preferably a pin shaft, and the fixing member 4 is preferably an open pin.

[0038] The lifting portion 22 includes a lifting block; the connecting member 3 is respectively inserted through the lifting block and the output end of the lifting mechanism 1, and the fixing member 4 is connected to the connecting member 3 to connect the connecting member 3, the lifting block and the lifting mechanism 1. The lifting block is provided with a lifting hole, the connecting member 3 is inserted through the lifting hole of the lifting block and the output end of the lifting mechanism 1, and then the fixing member 4 is inserted on the connecting member 3 to prevent the connecting member from detaching from the lifting block and the output end of the lifting mechanism, that is, to fix the connecting member, the lifting block and the lifting mechanism, thereby realizing the fixed connection between the connecting seat and the lifting mechanism.

[0039] Preferably, the number of the lifting blocks is two, and they are arranged in parallel. The output end of the lifting mechanism is placed between the two lifting blocks. The connecting piece passes through the two lifting blocks and the output end of the lifting mechanism, and the fixing piece is inserted into the connecting piece and clamped on one of the lifting blocks, so that the connecting piece cannot be separated from the lifting blocks and the output end of the lifting mechanism.

[0040] Furthermore, the locking portion 23 includes a locking block. As Figures 1-3 shown, the locking mechanism includes a locking seat 7, the locking seat 7 is fixedly installed on the locking block, and both the driving mechanism 5 and the plug-in member 6 are installed on the locking seat 7. That is, the driving mechanism and the plug-in member are fixedly installed on the locking block through the locking seat. The driving mechanism drives the plug-in member through the locking seat, so that the plug-in member, the locking block and the mold are connected or separated.

[0041] Preferably, as Figure 2 shown, the locking seat 7 is provided with a guiding cavity 71, the plug-in member 6 is arranged in the guiding cavity 71, and the driving mechanism 5 drives the plug-in member 6 to move in the guiding cavity 71, so that the plug-in member 6 can pass through the locking block and the mold 200. The shape of the locking seat 7 is a cylinder, and the guiding cavity 71 penetrates through both ends of the locking seat 7. The locking block is provided with a locking hole. One end of the locking seat is connected to the locking block, and the guiding cavity and the locking hole are communicated; the other end is connected to the driving mechanism, and the output end of the driving mechanism is placed in the guiding cavity and connected to the plug-in member. The plug-in member and the locking hole are arranged corresponding to each other. When the driving mechanism is started, its output end pushes the plug-in member out of the guiding cavity, passes through the locking hole and the hook of the mold, so that the locking block and the mold are connected, that is, the connecting seat and the mold are connected. When the connecting seat rises and falls, it drives the mold to rise and fall. When the driving mechanism is closed, its output end moves in the opposite direction, driving the plug-in member to move into the guiding cavity, so that the plug-in member is separated from the hook of the mold, thereby separating the mold and the connecting seat. At this time, the lifting mechanism drives the connecting seat to rise, and the mold leaves the pressing chamber under the action of the mold cart. Therefore, the utility model drives the plug-in member to move back and forth in the guiding cavity through the driving mechanism, so that the mold and the connecting seat are connected or separated.

[0042] Preferably, the number of the locking blocks is two, and they are arranged in parallel. The hook 201 of the mold 200 is placed between the two locking blocks, and the plug-in member 6 passes through the hook 201 and the two locking blocks, so that the hook and the locking block are connected, that is, the connecting seat and the mold are connected. When the plug-in member is driven away from the hook and one of the locking blocks, the connecting seat and the mold are separated, so that the connecting seat rising or falling will not drive the mold.

[0043] Preferably, as Figures 1-2 shown, the driving mechanism 5 is connected to the plug-in member 6 through a joint 8, and the joint 8 is arranged in the guiding cavity 71. The joint 8 is preferably a ball eye joint. The setting of the joint ensures the reliability of the connection between the driving mechanism and the plug-in member.

[0044] Furthermore, the utility model further includes a guiding assembly for guiding the connecting seat 2. The guiding assembly is installed on the top of the pressing chamber 100 and is connected to the connecting seat 2. The arrangement of the guiding assembly ensures that the connecting seat moves in a predetermined direction without deviation, thereby ensuring the stability and reliability of the mold lifting.

[0045] Specifically, as Figure 2 shown, the connecting seat 2 further includes a guiding portion 24 provided on the base portion 21, and the guiding portion 24 includes a guiding block. As Figures 1-3 shown in FIGS. 4 and 5, the guiding assembly includes a guiding sleeve 9, a guiding shaft 10 and a fastening member 11. The guiding sleeve 9 is fixedly installed on the top of the pressing chamber 100. One end of the guiding shaft 10 is inserted through the guiding sleeve 9, and the other end is fixedly connected to the guiding block through the fastening member 11. When the connecting seat moves up and down, it drives the guiding shaft to move up and down. The guiding shaft moves up and down in a predetermined direction under the limiting action of the guiding sleeve, thereby ensuring that the connecting seat moves up and down in a predetermined direction.

[0046] Preferably, the central axes of the guiding sleeve 9 and the lifting mechanism 1 are arranged parallel to each other, ensuring that the guiding direction of the guiding sleeve is the same as the driving direction of the lifting mechanism, and further ensuring that the connecting seat moves up and down in a predetermined direction.

[0047] Wherein, the guiding block is provided with a guiding hole, and the guiding shaft 10 is inserted through the guiding hole and fixed to the guiding block through the fastening member 11. The fastening member 11 is preferably a nut. The guiding block and the guiding shaft 10 are perpendicularly connected to each other.

[0048] It should be noted that the base portion 21 includes a base block; the lifting block, the locking block and the guiding block are perpendicularly connected to each other through the base block. The lifting block is arranged on the top of the base block and is perpendicularly connected to the base block; the locking block is arranged at the bottom of the base block and is perpendicularly connected to the base block; the lifting block and the locking block are perpendicularly connected to each other through the base block; the guiding block is arranged on the side of the base block, and the guiding block and the base block are in the same plane. That is, the guiding block is perpendicularly connected to the lifting block and the locking block respectively.

[0049] Preferably, as Figure 2As shown, the latch mechanism further includes a first sensor 12 and a second sensor 13 mounted on the drive mechanism 5. The first sensor 12 is disposed near the output end of the drive mechanism 5, and the second sensor 13 is disposed away from the output end of the drive mechanism 5. The first sensor 12 and the second sensor 13 are respectively used to detect the operating state of the drive mechanism 5. When the drive mechanism starts and its output end extends, the plug-in member connects the connecting seat and the mold. The first sensor detects this state and sends a signal to the control system. At this time, the control system controls the lifting mechanism to start, lift the connecting seat, and then drive the mold to lift; when the drive mechanism is closed and its output end contracts, the plug-in member retracts, the connecting seat and the mold are separated, the second sensor detects this state and sends a signal to the control system. At this time, the control system controls the lifting mechanism to start and only lift the connecting seat.

[0050] Preferably, the first sensor 12 and the second sensor 13 are respectively magnetic switches.

[0051] Preferably, the present invention further includes a travel switch (not shown in the figure) disposed in the pressing chamber 100. The travel switch is used to detect the position of the mold trolley 300, so as to further control the operation of the mold lifting mechanism. The travel switch can adopt the structure of the existing technology and will not be introduced in detail here.

[0052] It should be noted that as Figure 3 shown, the number of the mold lifting mechanisms is four, which are respectively disposed at the four corners of the mold 200 and move synchronously to ensure the stable and reliable lifting and lowering of the mold.

[0053] The specific working process is as follows: as Figures 1-5 shown, the mold trolley 300 transports the mold 200 into the pressing cavity 101. The lifting mechanism 1 drives the connecting seat 2 to descend, and then the drive mechanism 5 starts. The plug-in member 6 connects the connecting seat 2 and the mold 200. The lifting mechanism 1 drives the connecting seat 2 to rise, and the mold trolley 300 leaves the pressing cavity 101. The lifting mechanism 1 drives the connecting seat 2 to descend, the drive mechanism 5 is closed, and the plug-in member 6 leaves, separating the connecting seat 2 and the mold 200. The lifting mechanism 1 drives the connecting seat 2 to rise again.

[0054] After pressing is completed, the lifting mechanism 1 drives the connecting seat 2 to descend, the drive mechanism 5 starts, the plug-in member 6 connects the connecting seat 2 and the mold 200, and the lifting mechanism 1 drives the connecting seat 2 to rise. The mold trolley 300 enters the pressing cavity 101 again. The lifting mechanism 1 drives the connecting seat 2 to descend, the drive mechanism 5 is closed, and the plug-in member 6 leaves, separating the connecting seat 2 and the mold 200. The lifting mechanism 1 drives the connecting seat 2 to rise again. Finally, the mold trolley 300 transports the mold 200 away.

[0055] In summary, the present utility model provides a mold lifting device, which has a simple structure, occupies a small space, and has a long service life.

[0056] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
