Description

Technical Field

[0001] This utility model relates to the field of stamping production technology, and specifically to an auxiliary mold mounting device. Background Technology

[0002] In the stamping process of modern manufacturing, small and medium-sized presses and punches, as basic equipment, are increasingly facing limitations in their worktable structure and mold installation methods. Currently, most of these machines are equipped with fixed machine tool worktables, and the mold installation process mainly relies on a semi-manual operation mode assisted by forklifts. Specifically, during operation, the mold must first be lifted to the same height as the machine tool worktable using a forklift. Then, multiple workers push the mold from the forklift's forks to the edge of the machine tool worktable, and then move it laterally to the designated installation area.

[0003] During the process of transferring the mold from the forklift to the edge of the machine tool table, the forklift forks are prone to swaying up and down under the immense weight of the mold, and due to uneven force exerted by the workers, making it difficult to push the mold from the forklift to the machine tool table. Moreover, even after the mold is lifted from the forklift to the edge of the machine tool table, the workers still need to work together to push the mold to the designated installation area, which takes a lot of time and effort.

[0004] In other words, because fixed machine tool worktables lack active height adjustment capabilities, they cannot proactively adapt to the height of the molds on the forklift. When dealing with heavy molds, manual pushing operations usually require multiple people working together, which is difficult, time-consuming, and severely restricts production efficiency.

[0005] In addition, the contact surface between the forklift forks (i.e., fork arms) and the bottom surface of the mold is usually very rough, and the resulting sliding friction will cause greater resistance. Especially under heavy load conditions, this resistance will greatly increase the difficulty of moving the mold, further prolong the installation cycle and increase the labor intensity of the operators.

[0006] Furthermore, during the manual pushing of heavy molds, uneven force or operational errors by workers can easily lead to safety accidents such as mold tipping over or slipping, resulting in injuries.

[0007] Therefore, how to solve the above problems has always been a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing an auxiliary mold-loading device. This device effectively solves the operational difficulties encountered during mold loading and changing on a fixed worktable, and features low cost, simple structure, high reliability, and strong versatility.

[0009] The objective of this utility model is achieved through the following solution: An auxiliary mold-assembly device includes several auxiliary mold-assembly mechanisms, each of which includes a crossbeam for auxiliary mold assembly, a support column for connecting to the crossbeam, and a mounting block for connecting the crossbeam to a machine tool. During mold assembly, the mounting block is set on the side wall of the machine tool and connected to one end of the crossbeam. The other end of the crossbeam is connected to the support column, which can be freely adjusted in height so that the top surface of the crossbeam is flush with the top surface of the machine tool, so as to push the mold to the top surface of the machine tool.

[0010] Preferably, the support column includes a fixed support part and an adjustable support part. One end of the adjustable support part is connected to the crossbeam to provide support for the crossbeam. The other end of the adjustable support part is threadedly connected to one end of the fixed support part. The other end of the fixed support part is supported on the ground, so that the height of the support column can be freely adjusted by rotating the thread.

[0011] Preferably, the connection between one end of the crossbeam and the support column is a snap-fit ​​connection or a bolted connection.

[0012] Preferably, the connection between the mounting block and the crossbeam is a snap-fit ​​connection or a bolted connection.

[0013] Preferably, the crossbeam includes two opposing frame plates, with multiple roller shafts between the two frame plates, and each roller shaft is equipped with a roller for assisting in mold assembly.

[0014] Preferably, the crossbeam includes two opposing support plates, with an anti-reverse block between the two support plates to prevent the mold from retracting during the pushing process.

[0015] Preferably, a plurality of connectors are provided between the two frame plates of the crossbeam for fixing the two frame plates together.

[0016] Preferably, one side of the mounting block is used to fix it to the machine tool, and the other side of the mounting block is provided with a groove; The two brackets of the crossbeam are each provided with a protrusion at one end where they connect to the mounting block, for engaging with the groove to form a snap-fit.

[0017] The beneficial effects of this utility model are as follows: An auxiliary mold-assembly device includes several auxiliary mold-assembly mechanisms, each of which includes a crossbeam for auxiliary mold assembly, a support column for connecting to the crossbeam, and a mounting block for connecting the crossbeam to a machine tool. During mold assembly, the mounting block is set on the side wall of the machine tool and connected to one end of the crossbeam. The other end of the crossbeam is connected to the support column, which can be freely adjusted in height so that the top surface of the crossbeam is flush with the top surface of the machine tool, so as to push the mold to the top surface of the machine tool.

[0018] During mold installation, due to the large weight of the mold, the traditional forklift loading and unloading method has obvious defects. That is, the forklift forks (i.e., fork arms) are prone to vertical swaying under load, making it difficult for workers to transfer the mold stably between the forklift and the machine tool table, which greatly increases the difficulty of mold installation and operational risks.

[0019] This utility model's height-adjustable auxiliary mold-loading device, by stably fixing it to one side of the machine tool, aligns the top surface of its crossbeam with the top surface of the machine tool. During mold installation, the forklift's forks can be inserted between the crossbeams to smoothly unload the heavy-duty mold onto the crossbeam of the auxiliary mold-loading device. This allows workers to apply less horizontal thrust compared to traditional transfer methods, significantly improving operational safety and work efficiency during mold installation and replacement, and providing an efficient and reliable solution for mold loading and unloading operations.

[0020] Preferably, the support column includes a fixed support part and an adjustable support part. One end of the adjustable support part is connected to the crossbeam to provide support for the crossbeam. The other end of the adjustable support part is threadedly connected to one end of the fixed support part. The other end of the fixed support part is supported on the ground, so that the height of the support column can be freely adjusted by rotating the thread.

[0021] By causing relative rotation between the adjusting support and the fixed support, the height of the support column can be dynamically adjusted. This design allows the auxiliary mold-setting device to be adapted to machine tools of different height specifications, thereby effectively improving the versatility of the device.

[0022] Preferably, the connection between one end of the crossbeam and the support column is a snap-fit ​​connection or a bolted connection, so as to facilitate disassembly and transportation.

[0023] Preferably, the connection between the mounting block and the crossbeam is a snap-fit ​​connection or a bolted connection, to facilitate disassembly and transportation.

[0024] Preferably, the crossbeam includes two opposing frame plates, with multiple roller shafts between the two frame plates, and each roller shaft is equipped with a roller for assisting in mold assembly.

[0025] This invention converts sliding friction into rolling friction by setting rollers between two plates, significantly reducing the coefficient of friction between the contact surfaces. This greatly reduces the resistance when operators push the mold, significantly shortening the installation time and improving installation efficiency in installation scenarios involving heavy molds.

[0026] Preferably, the crossbeam includes two opposing support plates, with an anti-reverse block between the two support plates to prevent the mold from retracting during the pushing process, thereby significantly improving the safety and reliability of the installation process.

[0027] Preferably, a number of connectors are provided between the two frame plates of the crossbeam, and the two frame plates are fixedly connected together during the molding process through these connectors.

[0028] This invention uses several connectors to fix two frame plates together, which not only effectively improves the load-bearing capacity of the crossbeam, but also ensures that the two frame plates are easily detachable, facilitating later maintenance.

[0029] Preferably, one side of the mounting block is used to fix it to the machine tool, and the other side of the mounting block is provided with a groove; The two brackets of the crossbeam are each provided with a protrusion at one end where they connect to the mounting block, for engaging with the groove to form a snap-fit.

[0030] This utility model, through the cooperation of grooves and protrusions, can effectively form a longitudinal positioning and anti-detachment structure, as well as a lateral limiting mechanism. While ensuring that the crossbeam is reliably connected to the machine tool in the vertical direction and avoiding detachment due to external forces, it can effectively resist the lateral thrust generated during mold installation and prevent the crossbeam from undergoing horizontal displacement or deflection.

Detailed Implementation

[0032] like Figures 1 to 6 As shown, an auxiliary mold-loading device includes several auxiliary mold-loading mechanisms. In practical applications, the number of mechanisms can be adaptively adjusted according to the width of the machine tool's worktable. Typically, the auxiliary mold-loading mechanisms are installed in pairs, and when arranged on the side of the worktable, the spacing between each mechanism must meet the following technical requirements: the spacing between two adjacent auxiliary mold-loading mechanisms should be compatible with the width of the forklift forks and the working position, ensuring that the forklift can accurately place the mold on the bearing surface of the auxiliary mold-loading device.

[0033] The auxiliary mold-assembly mechanism includes a crossbeam 1 for auxiliary mold assembly, a support column 2 for connecting to the crossbeam 1, and a mounting block 3 for connecting the crossbeam 1 to the machine tool 8, wherein: The crossbeam 1 includes two opposing support plates 101, with multiple roller shafts spaced apart between the two support plates 101. Each roller shaft is equipped with a roller 4, and each roller shaft is rotatably connected to the support plate 101. This arrangement allows the top surface of the crossbeam to have a low coefficient of friction, so that when the mold is placed on it, it can be easily pushed to facilitate mold loading.

[0034] Several connectors are provided between the two support plates 101 of the crossbeam 1 to fix the two support plates together. The presence of the connectors makes it easy to disassemble and maintain the two support plates.

[0035] Furthermore, an anti-reverse block 5, an anti-reverse block spindle 6, and an anti-reverse limiting shaft 7 are provided on the side away from the mounting block 3 between the two mounting plates 101 to prevent the mold from retracting during the pushing process. Specifically, the anti-reverse block 5 includes a blocking part 501 and a tail part 502. A connecting hole is provided on the side near the blocking part 501. An angle is designed on the top of the blocking part 501 so that when the mold is pushed in, after contacting the blocking part 501, the anti-reverse block 5 can rotate clockwise around the anti-reverse block spindle 6, thus not hindering the mold from being pushed in. The aforementioned anti-reverse limiting shaft 7 is located on the side of the tail part 502 near the machine tool so that when the mold retracts, the rotation angle of the anti-reverse block 5 is limited, thereby limiting the movement of the mold, which significantly improves the convenience, safety, and reliability of the installation process.

[0036] Mounting block 3 is disposed on the side wall of machine tool 8 and connected to one end of crossbeam 1. The connection between mounting block 3 and crossbeam 1 is a snap-fit ​​or bolted connection, which is essentially a detachable connection for easy disassembly and transportation. One side of mounting block 3 is used to fix it to machine tool 8, and the other side of mounting block 3 is provided with a groove 301. The ends of the two support plates 101 of crossbeam 1 that are connected to mounting block 3 are provided with protrusions 1011 for engaging with groove 301 to form a snap-fit. A limiting part 1012 is also provided on the protrusion 1011. The limiting part 1012 abuts against the corresponding step surface in groove 301, so that crossbeam 1 will not move horizontally during use.

[0037] The other end of the crossbeam 1 is connected to the support column 2, which can be freely adjusted in height so that the top surface of the crossbeam 1 is flush with the top surface of the machine tool 8, so as to push the mold to the top surface of the machine tool 8.

[0038] The connection between the crossbeam 1 and the support column 2 is a snap-fit ​​connection or a bolted connection, which is essentially a detachable connection for easy disassembly and transportation. In this embodiment, a snap-fit ​​part 2021 is provided at the top of the adjusting support part 202. When in use, the snap-fit ​​part 2021 snaps into the crossbeam 1 to restrict the lateral movement of the crossbeam 1 during use.

[0039] The support column 2 includes a fixed support part 201 and an adjustable support part 202. One end of the adjustable support part 202 is connected to the crossbeam 1 to provide support for the crossbeam 1. The other end of the adjustable support part 202 is threadedly connected to one end of the fixed support part 201. The other end of the fixed support part 201 is supported on the ground, so that the height of the support column 2 can be freely adjusted by rotating the thread.

[0040] In other words, in this embodiment, the number of auxiliary mold-mounting mechanisms is flexibly configured according to the width parameters of the machine tool worktable during installation. The mounting block 3 is reliably installed on the side of the machine tool worktable using screw fastening, while the support column 2 is positioned on the side of the punch press worktable. The first protrusion 1011 at one end of the crossbeam 1 is embedded from top to bottom into the groove 301, and the other end is stably engaged in the engaging part 2021. By adjusting the distance between the support column 2 and the machine tool worktable, the crossbeam 1 is ensured to be fully engaged, and the height of the support column 2 is adjusted to make the crossbeam 1 flush with the height of the machine tool worktable.

[0041] The usage process of this utility model is as follows: During the installation or replacement of molds, the forklift's forks are used to move the molds above the crossbeam 1. The forks are then lowered so that they can pass through the gaps between the auxiliary mold-loading mechanisms from top to bottom, placing the molds onto the crossbeam 1. Subsequently, the workers only need to push the molds to move them from the crossbeam 1 to the worktable.

[0042] Based on the rotating structure design of the anti-retraction block 5, when the mold is pushed in, the anti-retraction block 5 is subjected to the pushing force of the mold, and its blocking part 501 rotates clockwise along the anti-retraction block spindle 6 to ensure that the mold can be smoothly introduced; when the mold is disengaged, the anti-retraction block 5 hangs down naturally under the action of gravity, and its blocking part 501 protrudes from the upper surface of the crossbeam 1 to form protection; if the mold retracts, the anti-retraction block 5 immediately rotates counterclockwise along the anti-retraction block spindle 6 until it forms rigid contact with the anti-retraction limit shaft 7, thereby effectively preventing the mold from sliding and forming a reliable anti-retraction protection mechanism.

[0043] In summary, the aforementioned auxiliary molding device, through its modular design, can be flexibly configured according to machine tool specifications, enabling quick and simple installation. Furthermore, the height-adjustable support column 2 structure can adapt to the worktable height of different machine tool models, significantly improving the device's versatility. In addition, this device adopts a detachable structural design, allowing for quick disassembly when not in use, facilitating storage and transportation, and effectively saving operating space.

[0044] Comparative experiments have confirmed that, compared with the traditional forklift direct loading and unloading method, this method not only significantly reduces the number of personnel required for mold installation but also shortens the single installation time of the mold by at least 10 minutes, greatly improving production efficiency and reducing production costs. Most importantly, using this invention for mold installation virtually eliminates safety accidents such as mold tipping or slipping caused by uneven force or operational errors during the installation process, significantly reducing the labor intensity of workers while greatly ensuring their occupational safety.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications made to the present utility model by those skilled in the art without departing from the spirit of the present utility model shall fall within the protection scope of the present utility model.
