Description

Technical Field

[0001] The invention relates to the field of large-scale mould transport equipment, and in particular to a transport equipment for injection moulds of automobile parts. Background Art

[0002] Auto parts molds are indispensable tools in the automotive manufacturing industry and are widely used in the production of various types of auto parts, such as manifolds, covers, oil-gas separators, etc. for automobile engines. Most of them are currently injection molded parts, that is, they are produced using the injection molding process. Different molds have different sizes and are usually placed on mold racks for storage, which is convenient for management and retrieval. For large parts molds, different equipment is required for transportation and storage. Usually, each storage rack corresponds to different transportation equipment, and the two need to be used in conjunction. It has high requirements for the storage rack. In addition to its own placement function, it also needs to have certain transportation and movement functions.

[0003] Therefore, in actual production, for a single storage rack with a placement function, traditional transportation equipment also needs to cooperate with other equipment for picking up and storing, which has a high cost of use and there are certain inconveniences in use. In addition, due to the large size and weight of large parts molds, manual cooperation is extremely laborious and has a high risk factor. Summary of the invention

[0004] The main purpose of the present invention is to provide a transfer device for an injection mold of an automobile part, which can effectively solve the problems in the background technology.

The workbench contains a driving force inside to enable the plurality of second rollers to rotate in the same direction at the same time.

[0006] The driving assembly includes a first gear, which is fixedly sleeved on the circular shaft of the first roller. A gear shaft is movably installed inside the support frame. The first gear and the gear shaft are connected through a first toothed belt transmission. The first gear, the gear shaft and the first toothed belt are all located inside the support frame, and a linkage assembly is arranged between the support frames.

[0007] The linkage assembly includes a plurality of second gears, which are movably mounted inside the mounting frame through a long rod, and are located between two adjacent support frames. The second gears movably penetrate the mounting frame and mesh with adjacent gear shafts, and the gear shaft inside the mounting frame close to the fixed transport area can be connected to the driving force transmission inside the workbench through a transmission toothed belt.

[0008] The height of the second gear is lower than the position of the gear shaft. Connecting plates are movably installed at both ends of the circular axis of the gear shaft. The connecting plates can rotate along the circular axis. The two ends of the long rod are movably installed on the surfaces of the two connecting plates respectively. A lifting assembly is installed inside the mounting frame for adjusting the height of the second gear.

[0009] The positioning assembly includes a limiting rod, which movably passes through each support frame. A connecting spring is fixedly installed between two adjacent support frames. The connecting spring is in a stretched state and is sleeved on the surface of the limiting rod.

[0010] There are multiple limit rods, which are equidistantly arranged on the surface of the support frame. There are multiple second gears fixedly sleeved on the surface of each long rod, which are respectively located between two adjacent limit rods.

[0011] The lifting assembly includes a support rod, which is against the surface of each long rod and is located below the long rod. A rotatable screw rod is arranged below the support rod, and the screw rod thread passes through a mounting frame. A power assembly is arranged below the mounting frame.

[0012] There are multiple support rods, which are equidistantly arranged on the surface of the long rod. The multiple support rods are fixedly connected by a mounting plate. A bearing is embedded on the lower surface of the mounting plate. The screw is fixedly installed inside the bearing. There are at least two screws.

[0013] The power assembly includes at least two third gears, both of which are fixedly sleeved on the surface of the screw, and the two third gears are connected by a second toothed belt transmission. A driving motor is arranged under one of the third gears, and the output shaft of the driving motor is fixed inside the third gear.

[0014] The driving motor, the third gear and the second gear are all installed inside the base frame. At least two square tubes are movably installed inside the base frame. The third gear is fixedly sleeved on the surface of the square tube. A square rod is fixedly installed on the lower end of the screw rod, and the square rod is movably inserted into the inside of the square tube.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by setting a base frame, a workbench, a first roller and a second roller, a worker moves the entire base frame to the front position of the storage rack, uses a gantry to lift the workbench, moves it to the position below the large mold that needs to be taken, and aligns the support frame between two adjacent fixed rods.

It does not need to be used through the cooperation of multiple devices, which is more convenient and has lower costs. In the present invention, a connecting plate, a gear shaft, a second gear and a support frame are provided, and the connecting plate rotates. Since the distance between the second gear and the gear shaft is constant, the gear shaft will also rotate accordingly. However, the second gear will squeeze the unconnected gear shaft and ensure meshing at the same time, thereby changing the position of the gear shaft and further changing the distance between the support frames. This not only improves the scope of application, but also ensures that the same power source is used inside all the support frames, thereby saving usage costs. In the present invention, by arranging a screw rod, a support rod and a long rod, the rotation of the screw rod changes the height of the support rod, which will squeeze the long rod and change the position of the long rod. The screw rod is self-locking due to its own characteristics, and the structure is simpler and more convenient to use. In the present invention, by arranging square tubes and square rods, when the square tubes rotate, the square rods will be driven to rotate, thereby causing the screw rods to rotate and rise, driving the square rods to move as well. However, since the square rods are inserted into the inside of the square tubes, the movement of the workbench will not be affected. At the same time, the driving motor, the third gear and the second gear are all installed inside the base frame to prevent the workbench itself from having a large dead weight and reduce the load on the gantry.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0019] like Figure 1-9 As shown, a transfer device for an automobile parts injection mold comprises a movable chassis 1, such as Figure 2 As shown, rollers are installed at the bottom of the base frame 1 to facilitate its movement, and a workbench 2 and a gantry 3 are installed above the base frame 1. Figure 1 As shown, the gantry 3 is fixed on the top of the base frame 1, and the workbench 2 is placed on the top of the base frame 1. The workbench 2 runs through the inner side of the gantry 3 horizontally. The gantry 3 contains a driving force to make the workbench 2 move longitudinally. The workbench 2 is divided into two areas, namely a fixed transportation area and a mobile transportation area. The gantry 3 is located between the fixed transportation area and the mobile transportation area. A gap is set between the fixed transportation area and the mobile transportation area. The base frame 1 moves the workbench 2 to the position of the storage rack. By changing the height of the workbench 2, large molds of different heights can be taken. The mobile transport area includes a rectangular frame-shaped mounting frame 4, a plurality of support frames 5 are movably mounted inside the mounting frame 4, and in this embodiment, the number of the support frames 5 is set to seven, a first roller 6 is mounted inside the support frame 5, and each support frame 5 corresponds to a first roller 6, a driving component is mounted inside the mounting frame 4, and is used to rotate each first roller 6, and a positioning component is mounted on the surface of the support frame 5, and is used to fix the position of the support frame 5; The fixed transport area includes a plurality of second rollers 7, which are equidistantly arranged on the surface of the workbench 2. The heights of the first roller 6 and the second roller 7 are exactly the same. The workbench 2 contains a driving force inside so that the plurality of second rollers 7 rotate in the same direction at the same time.

[0020] In actual production, the storage rack is usually installed through multiple fixed rods and an external frame. Therefore, the staff moves the entire base frame 1 to the front position of the storage rack and uses the gantry 3 to lift the workbench 2. The driving force of the gantry 3 is a hydraulic device until it moves to the position below the large mold that needs to be taken, and aligns the support frame 5 between two adjacent fixed rods. At this time, when the workbench 2 moves upward again, the large mold can be lifted up. The cooperation of the first roller 6 and the second roller 7 can move the mold to the surface of the workbench 2. At the same time, the distance between the support frames 5 can also be adjusted according to the actual distance between the fixed rods of the storage rack, thereby expanding the scope of use.

[0021] The drive assembly includes a first gear 8, such as Figure 4 As shown, in the present embodiment, there are two first gears 8, which are symmetrically located at both ends of the first roller 6. The first gear 8 is fixedly sleeved on the circular axis of the first roller 6. A gear shaft 9 is movably installed inside the support frame 5. The first gear 8 and the gear shaft 9 are connected by a first toothed belt 10. There are also two first toothed belts 10, which ensure that during the rotation of the first roller 6, the two ends thereof are subjected to the same external force, thereby ensuring stability during use. The first gear 8, the gear shaft 9 and the first toothed belt 10 are all located inside the support frame 5. A linkage assembly is provided between the support frames 5, which ensures that the same power source is used inside all the support frames 5, thereby saving use costs.

[0022] The linkage assembly includes multiple second gears 11, which are movably installed inside the mounting frame 4 through a long rod 12. The second gear 11 is fixedly connected to the long rod 12. The second gear 11 is located between two adjacent support frames 5. The second gear 11 movably passes through the mounting frame 4 and meshes with the adjacent gear shaft 9. The gear shaft 9 inside the mounting frame 4 near the fixed transport area can be connected to the driving force inside the workbench 2 through a transmission toothed belt. When one of the second gears 11 rotates forward, the gear shaft 9 meshing with it will reverse, and then the second gear 11 on the other side will also rotate forward, thereby ensuring that all the second gears 11 rotate forward. Since the second gear 11 is connected to the first roller 6 through the first toothed belt 10, the first roller 6 will also rotate forward, thereby ensuring that the rotation direction of all the first rollers 6 is exactly the same.

[0023] The height of the second gear 11 is lower than the position of the gear shaft 9, ensuring that the position of the gear shaft 9 can be squeezed and moved when the second gear 11 moves upward. Connecting plates 13 are movably installed at both ends of the circular axis of the gear shaft 9, and the connecting plates 13 can rotate along the circular axis. The two ends of the long rod 12 are movably installed on the surfaces of the two connecting plates 13 respectively. A lifting assembly is installed inside the mounting frame 4 for adjusting the height of the second gear 11. The second gear 11 and the connected gear shaft 9 are a whole.

[0024] When the distance between the support frames 5 needs to be adjusted, the connecting plate 13 is rotated. Since the distance between the second gear 11 and the gear shaft 9 is constant, the gear shaft 9 will also rotate accordingly. However, the second gear 11 will squeeze the unconnected gear shaft 9 and ensure engagement at the same time, thereby changing the position of the gear shaft 9 and further changing the distance between the support frames 5.

[0025] The positioning assembly includes a limit rod 14, which is fixedly installed inside the mounting frame 4. The limit rod 14 movably passes through each support frame 5 to ensure that the support frame 5 will not deviate when moving along the limit rod 14, and at the same time provide support force for the support frame 5 to ensure its stability when transporting large molds. A connecting spring 15 is fixedly installed between two adjacent support frames 5, such as Fig. 9 As shown, there are multiple groups of connecting springs 15 , and the connecting springs 15 are in a stretched state. The connecting springs 15 are sleeved on the surface of the limiting rod 14 .

[0026] When the second gear 11 rotates around the gear shaft 9 connected to it, the second gear 11 will squeeze the gear shaft 9 on the other side. At this time, the gear shaft 9 will move in the horizontal direction, driving the support frame 5 to move along the axial direction of the limiting rod 14. The distance between the two adjacent support frames 5 will also increase. At this time, the connecting spring 15 will be stretched again, and the rebound force of the connecting spring 15 can ensure the engagement of the gear shaft 9 and the second gear 11.

[0027] There are multiple limit rods 14, which are equidistantly arranged on the surface of the support frame 5. There are multiple second gears 11 fixedly sleeved on the surface of each long rod 12, which are respectively located between two adjacent limit rods 14 to ensure that the meshing force of the gear shaft 9 is uniform and stable. The lifting component includes a support rod 16, which is against the surface of each long rod 12. The support rod 16 is located below the long rod 12. A rotatable screw 17 is provided below the support rod 16. The screw 17 threadably penetrates the mounting frame 4. A power component is provided below the mounting frame 4. When the support rod 16 rises and moves, it will squeeze the long rod 12 to change the position of the long rod 12, thereby changing the position of the second gear 11. The height of the support rod 16 is changed by rotating the screw 17, and the screw 17 is self-locking through the characteristics of the screw 17 itself, so that the structure is simpler and more convenient to use.

[0028] There are multiple support rods 16, which are equidistantly arranged on the surface of the long rod 12. The multiple support rods 16 are fixedly connected by a mounting plate 18 to ensure that the surface of the long rod 12 is sufficiently supported. A bearing 19 is embedded on the lower surface of the mounting plate 18, and a screw 17 is fixedly installed inside the bearing 19. There are at least two screws 17. In this embodiment, Figure 6 The number of the screw rods 17 shown is four, which can be more stable when the position of the mounting plate 18 is self-locked, and prevent the rebound force of the connecting spring 15 from driving the gear shaft 9 to rebound and squeeze the position of the second gear 11 excessively.

[0029] The power assembly includes at least two third gears 20, such as Figure 8 As shown, there are four third gears 20, two third gears 20 are fixedly sleeved on the surface of the screw 17, and the two third gears 20 are connected by a second toothed belt 21. A driving motor 22 is arranged under one of the third gears 20, and the output shaft of the driving motor 22 is fixed inside the third gear 20. When the driving motor 22 is started, it drives the corresponding third gear 20 to rotate, and drives all the third gears 20 to rotate through the second toothed belt 21, so that all the screws 17 rotate.

[0030] The driving motor 22, the third gear 20 and the second gear 11 are all installed inside the base frame 1 to prevent the workbench 2 from having a large deadweight. At least two square tubes 23 are movably installed inside the base frame 1. The third gear 20 is fixedly sleeved on the surface of the square tube 23. A square rod 24 is fixedly installed at the lower end of the screw 17. The square rod 24 is movably inserted into the inside of the square tube 23. When the square tube 23 rotates, it will drive the square rod 24 to rotate, so that the screw 17 rotates and rises, driving the square rod 24 to move as well. However, since the square rod 24 is inserted into the inside of the square tube 23, it has a certain adjustment space. When the workbench 2 moves, the square rod 24 is directly moved out from the inside of the square tube 23, and is also directly stuck in the inside of the square tube 23 when falling back.

[0031] It should be noted that the present invention is a transfer device for an injection mold of an automobile part. When in use, the driving motor 22 is started, driving the corresponding third gear 20 to rotate, and driving all the third gears 20 to rotate through the second toothed belt 21, so that the square tube 23 rotates, which will drive the square rod 24 to rotate, so that the screw 17 rotates and rises, driving the mounting plate 18 to move, and the mounting plate 18 squeezes the long rod 12 through the support rod 16 to change the position of the long rod 12. When the second gear 11 rotates around the gear shaft 9 connected thereto, the second gear 11 will squeeze the gear shaft 9 on the other side. At this time, the gear shaft 9 will move in the horizontal direction, driving the support frame 5 to move along the axial direction of the limit rod 14, and the distance between the two adjacent support frames 5 will also increase. At this time, the connecting spring 15 will be stretched again, and the resilience of the connecting spring 15 can ensure the meshing of the gear shaft 9 and the second gear 11. The operator moves the entire base frame 1 to the front position of the storage rack, and uses the gantry 3 to lift the workbench 2. The driving force of the gantry 3 can use hydraulic equipment until it moves to the position below the large mold that needs to be taken, and aligns the support frame 5 between the two adjacent fixed rods. At this time, when the workbench 2 moves upward again, the large mold can be lifted up, and the second roller 7 is started, and the gear shaft 9 inside the support frame 5 close to it is driven to rotate through any transmission toothed belt, and the gear shaft 9 drives the second gear 11 connected to it to rotate. When the second gear 11 rotates forward, the gear shaft 9 meshing with it will reverse, and then the second gear 11 on the other side will also rotate forward, thereby ensuring that all the second gears 11 rotate forward. Since the second gear 11 is connected to the first roller 6 through the first toothed belt 10 transmission, the first roller 6 will also rotate forward, thereby ensuring that the rotation direction of all the first rollers 6 is exactly the same, and then the large mold is moved to the surface of the workbench 2.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
