Description

Technical Field

[0001] The present invention relates to the technical field of mold transfer, and more specifically, to a mold transfer clamping device. Background Art

[0002] In the current mold transfer operation, the combination of overhead crane lifting and electric rail flat car is usually adopted. Using this method exposes many problems and disadvantages that cannot be ignored.

[0003] In terms of transfer efficiency, the operation process of overhead crane lifting is relatively cumbersome. Before each lifting, the operator needs to perform a series of preparatory work, including checking the status of the overhead crane equipment, confirming that there are no obstacles on the lifting route, etc. This process consumes a lot of time. Moreover, the lifting speed of the overhead crane is relatively slow, especially when lifting heavy molds, the speed will be further reduced to ensure safety. In addition, the overhead crane needs to frequently adjust its position and height during operation, and the positioning process takes a long time. Although the electric rail flat car runs relatively stably on the track, the track laying restricts its operating range. When encountering transfer tasks that require turning or crossing different areas, the mold often needs to be loaded and unloaded multiple times, increasing the transfer time.

[0004] In terms of stability, when the overhead crane is lifting, the mold is suspended in the air and is greatly affected by external factors such as the vibration during the operation of the overhead crane. When lifting large or irregularly shaped molds, the mold is prone to shaking, which not only increases the safety risk during the lifting process but also may cause the mold to collide and be damaged. The electric rail flat car runs on the track. If the track is worn, deformed, or the track connection is uneven, the flat car will jolt during operation, which will also affect the stability of the mold, causing the mold to be displaced or slip during transportation.

[0005] Therefore, how to provide a fixing device that can assist in mold transfer and improve the transfer efficiency and stability of the mold is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] An embodiment of the present invention discloses a mold transfer clamping device, including:

[0040] A support part 1, on the top surface of which a connection plate 13 is fixed, and the connection plate 13 can be bolted to the truss of the transfer device;

[0041] A clamping part 2, which includes a plurality of clamping columns 21 and positioning members 22; the plurality of clamping columns 21 are arranged in an array, and their upper ends are vertically slidably connected to the bottom surface of the support part 1, and the plurality of clamping columns 21 can clamp the mold; the plurality of positioning members 22 are detachably connected to the lower ends of the plurality of clamping columns 21 one by one, and the positioning members 22 can cooperate with the positioning table at the bottom end of the mold to support the mold;

[0042] A driving part 3, which is fixed to the bottom surface of the support part 1, and the output end of the driving part 3 is drivingly connected to the clamping column 21 to drive it to slide along the bottom surface of the support part 1.

[0043] In this embodiment, the support part 1 includes a support frame 11 and a support plate 12; the support frame 11 is a frame structure formed by a plurality of parallel cross beams and connecting beams; the support plate 12 is fixed to the top surfaces of the plurality of cross beams; the connection plate 13 is fixed to the top surface of the support plate 12.

[0044] As Figures 1 to 3 shown, there are three cross beams. The three cross beams are parallel and spaced apart on the same horizontal plane, and the three cross beams are connected into a frame structure by a plurality of connecting beams. The support plate is buckled and fixed to the top surfaces of the cross beams and the connecting beams, and the connection plate is fixed to the top surface of the support plate. The clamping device can be hoisted and transferred by connecting the connection plate to the truss of the transfer device and using the transfer device.

[0045] In some other specific embodiments, the number of the clamping columns 21 is four. The four clamping columns 21 are grouped in pairs and are symmetrically arranged at both ends of the bottom surface of the support part 1; a support beam 24 is fixed between the opposite side walls of each pair of the two clamping columns 21.

[0046] The clamping columns are arranged perpendicular to the cross beams. The upper ends of the four clamping columns are respectively located at the four corners of the two cross beams at the edges. The clamping columns are slidably connected to the bottom surface of the cross beams. The positioning members at the lower ends of the clamping columns can cooperate with the positioning table at the bottom end of the mold, and the positioning of the mold is realized through the positioning members to prevent the mold from having a horizontal displacement after being clamped by the clamping columns.

[0047] The shape of the positioning member is adapted to the shape of the positioning table of different molds. To facilitate the clamping of molds of different specifications, the positioning member is connected to the lower end of the clamping column by bolts, and different types of positioning members can be replaced to meet the use of the positioning tables of different types of molds.

[0048] To further optimize the above technical solution, the driving part 3 includes a cylinder 31 and a connecting member 32; the cylinder body of the cylinder 31 is fixed to the bottom surface of the supporting part 1; the connecting member 32 is fixed to the piston rod of the cylinder 31, and the connecting member 32 is fixed to the top surface of the supporting beam 24.

[0049] In this embodiment, there are two upper and lower supporting beams between adjacent clamping columns to ensure the synchronous sliding between the two clamping columns in each group and at the same time ensure the overall stability between the clamping columns; the cylinder body of the cylinder is fixed to the bottom surface of the middle cross beam, the piston rod faces the direction of the clamping column, the piston rod is fixed to the supporting beam through the connecting member, when the piston rod of the cylinder expands and contracts, it will drive the supporting beam to move synchronously, thereby realizing the sliding of the two clamping columns in each group, and realizing the sliding of the four clamping columns through two groups of cylinders. The cylinder can also provide a clamping force to ensure that the clamping column has enough force to clamp the mold and prevent the mold from shaking or displacing during the transportation process.

[0050] To further optimize the above technical solution, it further includes a fixing plate 4. The fixing plate 4 is L-shaped and has a horizontal plate and a vertical plate; the horizontal plate is bolted to the end of the bottom surface of the supporting part 1; the connecting member 32 is a Z-shaped plate, and the two horizontal plates of the connecting member 32 are respectively bolted to the top surface of the supporting beam 24 and clamped to the piston rod of the cylinder 31; the vertical plate of the connecting member 32 can abut against the vertical plate.

[0051] As Figure 4 shown, the fixing plate is an L-shaped plate. The horizontal plate of the fixing plate is bolted to the bottom surface of the connecting beam at the end and the position of the fixing plate corresponds to the connecting member; the connecting member is a Z-shaped plate, which has two horizontal plates and a vertical plate. The two horizontal plates are respectively bolted to the horizontal plate of the fixing plate and clamped to the piston rod; in this embodiment, a clamping member is fixed to the end of the piston rod of the cylinder. A "convex"-shaped card slot is opened at the end of the horizontal plate of the connecting member facing the piston rod. A circular card block is fixed to the end of the card block away from the piston rod, and the card block is clamped in the card slot to realize the fastening between the piston rod and the connecting member through the clamping method.

[0052] In some other specific embodiments, a buffer pad 5 is fixed to the side panel of the vertical plate opposite to the vertical plate.

[0053] The fixing plate limits the two sides of the expansion and contraction of the piston rod to prevent the piston rod from protruding from the supporting part, thereby preventing the occurrence of the situation that the clamping column slips off; a buffer pad is arranged between the connecting member and the fixing plate, and the buffer pad can prevent damage to the clamping device caused by vibrations, shaking, etc. during the operation of the air pipe, and improve the service life of the clamping device.

[0054] In other specific embodiments, to realize automatic control of the clamping device, a pneumatic electromagnetic control valve 33 is fixed on the bottom surface of the support part 1, and the pneumatic electromagnetic control valve 33 is connected to the oil chamber of the cylinder 31 through an air circuit; the pneumatic electromagnetic control valve 33 is connected to the control system in communication. A force sensor 23 is fixed on the positioning member 22; the force sensor 23 is connected to the pneumatic electromagnetic control valve 33 in communication.

[0055] The control system controls the pneumatic electromagnetic control valve to realize the extension and retraction of the cylinder piston rod, and uses the force sensor to feedback the clamping force of the clamping column, thereby realizing automatic control of the clamping operation of the clamping column. For example, by issuing tasks through the MES system, automatic grasping of the mold can be achieved.

[0056] The control system in this embodiment can realize automatic positioning. The control system can realize accurate placement of the mold at the predetermined position on the positioning piece, and the positioning block of the mold and the positioning piece are precisely matched; at the same time, it can realize one-key start, automatically complete the preparation work such as device self-inspection and lifting path planning, and greatly save the preliminary preparation time. Moreover, its lifting and running speed can be precisely controlled according to the weight and size of the mold, and the transfer speed can be maximized while ensuring safety. In the multi-task transfer scenario, the automation system can reasonably arrange the transfer order according to the preset task priority, avoid equipment idle waiting, and further improve the overall transfer efficiency.

[0057] The control system starts with one button, and the device automatically completes a comprehensive self-check of the equipment, covering key components such as mechanical structure, electrical system, force sensor, etc. The core of this technology is to build an efficient self-checking logic algorithm to quickly and accurately determine whether each part of the equipment is in normal operation, ensuring the reliability of the equipment before transportation.

[0058] Based on the mold location information, transfer destination and on-site spatial layout, the spatial analysis algorithm is used to automatically plan the optimal lifting path. This path planning needs to take into account factors such as obstacle avoidance and equipment operation restrictions to improve transfer efficiency.

[0059] In addition, on the one hand, the control system can grasp the fixing status of the mold and the operating status of the clamping device in real time through the intelligent fixing and monitoring system; on the other hand, it reduces the manual operation links, reduces the safety risks caused by human negligence or improper operation, and ensures the safety of operators and molds.

[0060] In some other specific embodiments, a series of standardized fixing modules can be designed for molds of different shapes, sizes, and weights, including the size and shape of the positioning parts, the height of the clamping columns, the position of the cylinders, and the telescopic amount of the piston rods. These modules can be quickly assembled and replaced through specific connection methods to achieve precise fixation of various molds. The key lies in designing a general and stable connection structure and the shape of the fixing modules adapted to different molds.

[0061] In this embodiment, a slide rail 14 is fixed to the bottom surface of the support part 1; a slider 25 slidably connected to the slide rail 14 is fixed to the upper end of the clamping column 21.

[0062] The length of the slide rail is adaptively designed according to the telescopic amount of the piston rod and the structural dimensions of the mold. Through the cooperation of the slide rail and the slider of the clamping column, and by utilizing the telescopic movement of the piston rod of the cylinder, the clamping column can slide along the slide rail.

[0063] To further optimize the above technical solution and prevent the clamping column from slipping off the slide rail, stoppers 15 are fixed to both ends of the slide rail 14.

[0064] The working process of the clamping device in this embodiment is as follows:

[0065] Preparation stage: Use the transfer equipment to move the clamping device near the mold placement position, and check whether all parts of the device are working properly, such as whether the positioning is accurate, whether the clamping part is flexible, whether the buffer pads and stoppers are in good condition, etc.

[0066] Positioning stage: Transport the mold under the clamping device, align the positioning table on the mold with the positioning part at the lower end of the clamping column, and initially position the mold on the clamping device. At this time, the positioning part will limit the mold in the horizontal direction.

[0067] Clamping stage: Start the cylinder, move the piston rod along the direction of the cylinder and gradually approach the mold, and apply sufficient clamping force to the mold. The magnitude of the clamping force is feedback through the force sensor to ensure that the mold will not displace during the transfer process.

[0068] Transfer stage: Firmly connect the clamping device to the truss of the transfer equipment through the connecting piece. After confirming the reliable connection, start the transfer equipment and transfer the mold together with the clamping device to the designated location.

[0069] Unloading stage: After reaching the designated position, place the mold at the unloading position, move the piston rod along the direction away from the cylinder, separate the mold from the clamping device, and complete the transfer and fixation work of the mold.
