Description

Technical Field

[0001] This utility model relates to the field of mold lifter technology, specifically a modular roller-type mold lifter. Background Technology

[0002] A roller-type mold lifter is a device that uses rollers to lift and move molds. It is a mold auxiliary device used in stamping, injection molding, and other equipment. It achieves the lifting and moving of the mold through a roller mechanism. It is installed on the machine platform to lift heavy molds, reducing the labor intensity of workers.

[0003] Chinese Patent Publication No. CN217315502U discloses a hydraulic roller type mold lifter, relating to the field of machining technology. It includes: a housing, multiple sets of roller mechanisms, each set equidistantly positioned horizontally within the housing, a hydraulic drive mechanism, also with multiple sets equidistantly positioned horizontally on the housing, and two lubrication mechanisms, each symmetrically positioned within the housing. Each lubrication mechanism can lubricate the roller mechanisms. This hydraulic roller type mold lifter, through the placement groove, spring, limiting block, and limiting hole, facilitates the installation and removal of the protective plate, avoiding the cumbersome installation and removal of the protective plate and the resulting difficulties in roller maintenance. Furthermore, through the mounting frame, lubricating sponge, lubrication pipe, and lubrication hole, the hydraulic roller type mold lifter lubricates the rollers, preventing them from failing to roll during use and affecting the movement of the mold.

[0004] Based on existing solutions and actual production and processing applications, the current modular roller-type mold lifters still have some problems, such as:

[0005] 1. The lubrication mechanism of the roller-type mold lifter is located inside the housing. When maintaining the lubrication mechanism, the protective mechanism and roller mechanism need to be disassembled before maintenance can be performed, which makes maintenance of the lubrication mechanism more difficult.

[0006] 2. Since the roller-type mold lifter has a complex structure, it is difficult to replace the internal structure of the mold lifter. Therefore, this utility model provides a modular roller-type mold lifter to solve the above-mentioned problems. Utility Model Content

[0007] The purpose of this utility model is to provide a modular roller-type mold lifter to solve the problems mentioned in the background art, where the lubrication mechanism of the roller-type mold lifter is located inside the housing. When maintaining the lubrication mechanism, it is necessary to disassemble the protective mechanism and the roller mechanism before maintaining the lubrication mechanism, which makes the maintenance of the lubrication mechanism difficult. Since the roller-type mold lifter is a complex structure, it is also difficult to replace the internal structure of the mold lifter.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a modular roller type mold lifter, including a mounting plate, which has a hydraulic cylinder body inside, and a housing is connected to the upper side of the hydraulic cylinder body;

[0009] Also includes:

[0010] The mounting block is installed on the upper left side of the mounting plate, and a connecting block is connected to the lower left side of the mounting plate. A module structure is connected to the right side of the mounting plate, and the module structure includes a fixing plate, a fixing rod, a fixing block, and a limiting rod. The fixing plate is installed on the upper right side of the mounting plate, and a fixing rod is connected to the upper side of the fixing plate. The fixing block is installed on the lower right side of the mounting plate, and a limiting rod is connected to the upper side of the fixing block.

[0011] A roller is installed inside a housing, and a pipe is connected to the upper outer side of the housing. A disassembly structure is connected to the upper side of the pipe, and the disassembly structure includes a limiting plate, a connecting block, and an installation rod. The limiting plate is installed on the upper side of the pipe, and a connecting block is connected to the upper outer side of the limiting plate. An installation rod is connected to the outer side of the connecting block.

[0012] Preferably, the mounting block and the fixing plate are slidably connected, and the vertical cross-sectional shape of the mounting block is a "T" shape.

[0013] Preferably, the fixing plate and the fixing rod are connected by a thread and the fixing plate limits the movement between the mounting block and the fixing plate.

[0014] Preferably, the connecting block and the fixing block are engaged, and the connecting block and the limiting rod are threaded.

[0015] Preferably, a connecting pipe is fixedly installed on the lower middle side of the pipeline, and a lubricating oil inlet pipe is connected to the outer side of the pipeline.

[0016] Preferably, the pipeline is connected to the lubricating oil inlet pipe via a quick-connect coupling.

[0017] Preferably, the limiting plate and the pipeline are connected by a snap-fit ​​connection, and the vertical cross-section of the limiting plate is an "L" shaped structure.

[0018] Preferably, the connecting block and the housing are interlocked, and the mounting rods are symmetrically distributed about the center line of the pipeline.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the modular roller type mold lifter is provided with a modular structure, which can modularize the roller type mold lifter, thereby allowing for the individual replacement of worn parts, and is provided with a disassembly structure, which can disassemble the pipeline, thereby enabling the pipeline to be replaced.

[0020] 1. By placing the mounting plate on the right side of the other, the mounting plate moves the mounting block and connecting block to the rearward side, causing the mounting block to slide rearward inside the fixed plate, thereby engaging the connecting block inside the fixed block. Rotating the fixing rod causes it to be threaded on the upper middle side of the fixed plate, thus threading the fixing rod inside the upper side of the mounting block. Rotating the limiting rod causes it to be threaded on the upper side of the fixed block, thus moving the limiting rod downward, thereby threading the limiting rod inside the upper side of the connecting block. This facilitates the assembly of the mounting plates, thereby facilitating the modularization of the mold lifter.

[0021] 2. By rotating the mounting rod, the mounting rod is threaded onto the outside of the connecting block, causing the mounting rod to move upwards. This allows the mounting rod to separate inside the housing. Pulling the limiting plate upwards causes the limiting plate to slide the connecting block upwards, thus separating the connecting block from the upper side of the housing. This, in turn, separates the limiting plate from the upper side of the pipeline. Pulling the pipeline upwards further separates the pipeline and connecting pipe from inside the housing, facilitating the disassembly and replacement of the pipeline.

[0022] 3. The lubricating oil enters the pipeline through the lubricating oil inlet pipe, and drips onto the outside of the roller through the connecting pipe installed on the lower side of the pipeline. This lubricates the roller and the housing. The hydraulic cylinder set in the middle of the mounting plate lifts the housing. When the mold moves, the mold drives the roller to rotate in the middle of the housing, which facilitates the movement of the mold. Attached Figure Description

[0033] 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.

[0034] Please see Figure 1-9 This utility model provides a technical solution: a modular roller-type mold lifter, comprising a mounting plate 1, a hydraulic cylinder body 2, a housing 3, a roller 4, a mounting block 5, a fixing plate 6, a lubricating oil inlet pipe 7, a fixing rod 8, a connecting block 9, a fixing block 10, a limiting rod 11, a pipeline 12, a connecting pipe 13, a limiting plate 14, a connecting block 15, and a mounting rod 16. In operation, the specific details are as follows... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9As shown, mounting plate 1 is fixedly mounted on the upper left side of the mounting plate 1, connecting block 9 is fixedly mounted on the lower left side of the mounting plate 1, fixing plate 6 is fixedly mounted on the upper right side of the mounting plate 1, fixing rod 8 is movably mounted on the upper middle side of the fixing plate 6, fixing block 10 is fixedly mounted on the lower right side of the mounting plate 1, and limiting rod 11 is movably connected on the upper middle side of the fixing block 10. When mounting plate 1 is manually placed to the right of another mounting plate 1 and pushed backward, the mounting plate 1 causes the mounting block 5 and connecting block 9 to slide backward under the pushing force. This allows the mounting block 5 to slide backward within the fixing plate 6 to a suitable position, thereby enabling the connecting rod 9 to slide backward. Connecting block 9 is engaged inside fixing block 10. Tightening fixing rod 8 causes fixing rod 8 to be threaded on the upper middle side of fixing plate 6, thereby causing fixing rod 8 to move downward and then threaded on the upper side of mounting block 5. Tightening limiting rod 11 causes limiting rod 11 to be threaded on the upper middle side of fixing block 10, thereby causing limiting rod 11 to move downward under the thread action between limiting rod 11 and fixing block 10, and then threaded on the upper side of connecting block 9, which facilitates the assembly of mounting plates 1 and facilitates the modularization of the lifting device.

[0035] Specific examples Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, a pipe 12 is movably installed on the upper middle side of the housing 3, a connecting pipe 13 is installed on the lower middle side of the pipe 12, a limiting plate 14 is connected to the upper end of the pipe 12, a connecting block 15 is fixedly installed on the outer side of the upper end of the limiting plate 14, and an installation rod 16 is connected to the outer side of the connecting block 15. Tightening the installation rod 16 causes the installation rod 16 to be threadedly connected to the outer side of the connecting block 15. Under the action of the thread between the installation rod 16 and the connecting block 15, the installation rod 16 moves upward, thereby separating the installation rod 16 inside the housing 3. Then, manually pulling the limiting plate 14 upward causes the limiting plate 14 to drive the connecting block 15 to slide upward, thereby separating the connecting block 15 on the upper side of the housing 3. This causes the limiting plate 14 to separate on the upper side of the pipe 12. Then, manually pulling the pipe 12 upward causes the pipe 12 to drive the connecting pipe 13 to separate inside the housing 3, which facilitates the disassembly and replacement of the pipe 12.

[0036] Specific examples Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, a hydraulic cylinder 2 is fixedly installed inside the middle of the mounting plate 1, a housing 3 is fixedly installed on the upper side of the hydraulic cylinder 2, a roller 4 is movably connected inside the housing 3, and a lubricating oil inlet pipe 7 is fixedly installed on the outside of the pipeline 12. The hydraulic cylinder 2, which is located inside the middle of the mounting plate 1, lifts the housing 3. When the mold moves, the mold drives the roller 4 to rotate inside the middle of the housing 3, which facilitates the movement of the mold. After lubrication, the lubricating oil enters the pipeline 12 through the lubricating oil inlet pipe 7, and drips onto the outside of the roller 4 through the connecting pipe 13 located on the lower side of the pipeline 12. This lubricating oil lubricates the roller 4 and the housing 3, making it convenient to lubricate the roller 4.
