Description

Technical Field

[0001] This utility model relates to the technical field of assembly and disassembly devices for injection systems, specifically an assembly and disassembly device for integrated and large-scale die-casting injection systems. Background Technology

[0002] A die-casting machine is a machine used for pressure casting. It injects liquid or semi-liquid metal at high speed into a die-casting mold cavity under high pressure, causing the metal to solidify and form a precision casting. Integrated die casting is a large-scale die-casting technology used to manufacture lightweight and simplified integrated body structures and battery structures for new energy vehicles. The die-casting machine's injection system (see attached image) Figure 6 The structure within the dashed box usually refers to the three parts: the material cylinder, the punch, and the injection rod. This part of a large die-casting machine typically has a large size and weight. However, the injection system of integrated and large die-casting machines is even larger in size and weight and has a more complex structure. Therefore, during maintenance, it is necessary to support and fix it during assembly and disassembly to assist in maintenance and replacement work.

[0003] When maintaining the injection rods in the injection system of a large die-casting machine, a simple bracket is usually used to suspend them in the air to facilitate assembly and disassembly maintenance. However, since the lengths and diameters of different injection rods are usually different, the same simple bracket cannot provide stable fixation for different injection rods. Some injection rods with mismatched dimensions may shake or slip during maintenance, causing inconvenience to the maintenance work and even causing personal injury. Therefore, in order to address the above problems, an integrated and large-scale die-casting injection system-specific assembly and disassembly device is proposed. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a dedicated assembly and disassembly device for integrated and large-scale die-casting injection systems. This device supports the injection rod through directional wheel sets and fixes it with a locking mechanism. During operation, the spacing between the directional wheel sets is adjustable, making it suitable for supporting and fixing injection rods of different diameters. The telescopic bracket can adjust its extension length, thus supporting the ends of injection rods of different lengths. Furthermore, the lifting platform can move up and down to meet the lifting requirements of injection heads of different sizes. This solves the technical problem in the prior art where the bracket cannot stably fix injection rods of different sizes, potentially causing the injection rod to shake or slip during maintenance.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An assembly and disassembly device for integrated and large-scale die-casting injection systems includes a support frame with several mounting beams fixedly mounted on it. Some of these beams have detachable directional wheel sets for supporting the injection rods. Because the spacing between the directional wheel sets is adjustable, it can support and fix injection rods of different diameters. A telescopic bracket, located at one end of the support frame, also has detachable directional wheel sets for supporting the injection rod ends. The telescopic bracket's adjustable extension length allows it to support injection rod ends of different lengths. A lifting platform, located at the other end of the support frame, also has detachable directional wheel sets for supporting the injection head. The lifting platform can move up and down, thus meeting the lifting requirements for injection heads of different sizes. A locking mechanism is used to press down and fix the injection rods.

[0007] In one possible implementation, the directional wheel assembly includes a fixed base plate with a hinge seat fixedly mounted on its upper end surface. Rollers are rotatably mounted on the hinge seat, which can lift and clamp the injection rod by the relatively arranged rollers, thereby fixing the rod. At the same time, the rollers can also reduce the friction with the outer wall of the rod, thus protecting the injection rod.

[0008] In one possible implementation, bolt holes are provided on the fixed base plate, and several sets of corresponding bolt holes are provided on the support frame, the telescopic bracket, and the lifting platform. The fixed base plate is connected to the above three components by bolts. The above structure allows the three directional wheel sets to be connected to different bolt holes, thereby realizing the adjustment of the position of the directional wheel sets to change the distance between the two rollers in the directional wheel sets to fit the injection rods of different diameters.

[0009] In one possible implementation, a groove is provided at one end of the support frame, and the telescopic bracket includes a C-shaped telescopic frame that is slidably disposed in the groove, on which a set of directional wheels is installed. Since the C-shaped telescopic frame can slide inward and outward, its outward extension length can be adjusted so that it can provide support for the ends of the injection rods of different lengths.

[0010] In one possible implementation, a fixed channel steel is bolted to the support frame, on which a first diagonal brace is fixedly installed. A supporting channel steel is fixedly installed at the top of the first diagonal brace, and the supporting channel steel slides in contact with the C-shaped telescopic frame. This structural form can support the C-shaped telescopic frame with the first diagonal brace and the supporting channel steel, preventing it from being easily deformed by pressure during the extension process. Furthermore, the C-shaped telescopic frame has several mating holes, and the supporting channel steel and the C-shaped telescopic frame are fixedly connected by bolts passing through the mating holes. This fixing method allows the C-shaped telescopic frame to remain fixedly connected to the supporting channel steel even when it extends to different lengths.

[0011] In one possible implementation, the lifting platform includes a guide plate fixedly connected to the support frame, and a second diagonal brace is fixedly connected between the guide plate and the support frame. Several guide rods are slidably arranged on the guide plate, and a platform is fixedly connected to the top of the guide rods. A set of directional wheels is installed on the platform. Since the platform can move up and down to change its position, it can drive the set of directional wheels on it to move and support the injection heads of different sizes.

[0012] In one possible implementation, a screw jack is fixedly mounted on the guide plate, with the top of its lifting rod rotatably connected to the platform. A turntable is fixedly connected to the end of its drive rod, and a dial is rotatably connected to the turntable. When it is necessary to adjust the height of the platform, the turntable is rotated by the dial, thereby driving the screw jack to work and raise or lower the platform.

[0013] In one possible implementation, the locking mechanism includes a fixed foot with a threaded rod fixedly mounted thereon. A cover pressure arc plate is sleeved on the rod, and a locking nut is threaded onto the threaded rod. In addition, a soft rubber pad is attached to the lower end face of the cover pressure arc plate. When it is necessary to fix the injection rod, tightening the locking nut will press down the cover pressure arc plate so that it fits tightly against the injection rod, thus fixing the injection rod by pressing it down. Furthermore, the soft rubber pad can increase the friction between the cover pressure arc plate and the injection rod, improving the fixing effect, and also protecting the injection rod from scratches on its outer wall.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The assembly and disassembly device of this injection system supports the injection rod through a set of directional wheels and fixes the injection rod with a locking mechanism. During operation, the spacing between the directional wheels can be adjusted, so it can be used to support and fix injection rods of different diameters. The telescopic bracket can adjust its extension length, so it can lift the ends of injection rods of different lengths. In addition, the lifting platform can move up and down to meet the lifting needs of injection heads of different sizes. Attached Figure Description

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 As shown, the integrated and large-scale die-casting injection system assembly and disassembly device provided in this embodiment includes a support frame 1, on which several mounting beams 11 are fixedly installed. Some of the mounting beams 11 are detachably mounted with directional wheel sets 2, which are used to support the injection rod. Since the spacing between the directional wheel sets 2 is adjustable, it can be used to support and fix injection rods of different diameters. A telescopic bracket 3 is located at one end of the support frame 1, on which directional wheel sets 2 are detachably installed, to support the end of the injection rod. Since the telescopic bracket 3 can adjust its extension length, it can support the ends of injection rods of different lengths. A lifting platform 4 is located at the other end of the support frame 1, on which directional wheel sets 2 are detachably installed, to support the injection head. Since the lifting platform 4 can move up and down, it can meet the lifting requirements of injection heads of different sizes. A locking mechanism 5 is used to press down and fix the injection rod.

[0026] like Figure 1 - Figure 2 As shown, the directional wheel assembly 2 includes a fixed base plate 21, on the upper end face of which a hinge seat 22 is fixedly provided. Rollers 23 are rotatably mounted on the hinge seat 22. The rollers 23 arranged opposite to each other can lift and clamp the injection rod, thereby fixing the rod. At the same time, the rollers 23 can also reduce the friction with the outer wall of the rod, thus protecting the injection rod.

[0027] The fixed base plate 21 has bolt holes, and the support frame 1, the telescopic bracket 3 and the lifting platform 4 each have several sets of corresponding bolt holes. The fixed base plate 21 is connected to the above three components by bolts. The above structure allows the three directional wheel sets 2 to be connected to different bolt holes, thereby realizing the adjustment of the position of the directional wheel sets 2 to change the distance between the two rollers 23 in the directional wheel sets 2 to fit the injection rods of different diameters.

[0028] like Figure 2 As shown, the support frame 1 has a groove at one end, and the telescopic bracket 3 includes a C-shaped telescopic frame 31 that is slidably disposed in the groove. A set of directional wheels 2 is installed on it. Since the C-shaped telescopic frame 31 can slide inward and outward, its outward extension length can be adjusted so that it can support the ends of the injection rods of different lengths.

[0029] In addition, a fixed channel steel 32 is bolted to the support frame 1, on which a first diagonal brace 33 is fixedly installed. A supporting channel steel 34 is fixedly installed at the top of the first diagonal brace 33. The supporting channel steel 34 slides in contact with the C-shaped telescopic frame 31. This structure can support the C-shaped telescopic frame 31 with the first diagonal brace 33 and the supporting channel steel 34, preventing it from being easily deformed by pressure during the extension process. Furthermore, the C-shaped telescopic frame 31 has several mating holes 311. The supporting channel steel 34 and the C-shaped telescopic frame 31 are fixedly connected by bolts passing through the mating holes 311. This fixing method allows the C-shaped telescopic frame 31 to remain fixedly connected to the supporting channel steel 34 even when it extends to different lengths.

[0030] like Figure 3 As shown, the lifting platform 4 includes a guide plate 41 fixedly connected to the support frame 1, and a second diagonal brace 42 is fixedly connected between the guide plate 41 and the support frame 1. Several guide rods 43 are slidably arranged on the guide plate 41, and a platform 44 is fixedly connected to the top of the guide rods 43. A set of directional wheels 2 is installed on the platform. Since the platform 44 can move up and down to change its position, it can drive the set of directional wheels 2 on it to move and play a supporting role for the injection heads of different sizes.

[0031] In order to drive the platform 44 to rise and fall as required, a screw jack 45 is fixedly installed on the guide plate 41. The top end of the lifting rod is rotatably connected to the platform 44, and the drive rod end is fixedly connected to the turntable 46. A dial 47 is rotatably connected to the turntable 46. When it is necessary to adjust the height of the platform 44, the turntable 46 is rotated by the dial 47, which in turn drives the screw jack 45 to work and raise or lower the platform 44.

[0032] like Figure 4As shown, the locking mechanism 5 includes a fixed foot 51, on which a threaded rod 52 is fixedly mounted. A cover pressure arc plate 53 is sleeved on the rod, and a locking nut 54 is threadedly connected to the threaded rod 52. In addition, a soft rubber pad 55 is attached to the lower end face of the cover pressure arc plate 53. When it is necessary to fix the injection rod, tightening the locking nut 54 can press down the cover pressure arc plate 53 so that it fits tightly with the injection rod, thus pressing down and fixing the injection rod. Furthermore, the soft rubber pad 55 can increase the friction between the cover pressure arc plate 53 and the injection rod, improve the fixing effect, and also protect the injection rod from scratches on its outer wall.

[0033] The working principle and usage process of this utility model:

[0034] The assembly and disassembly device of the injection system supports the injection rod through the directional wheel set 2 and fixes the injection rod with the locking mechanism 5. In the specific operation, the spacing between the directional wheel sets 2 is adjustable, so it can be used to support and fix injection rods of different diameters. The telescopic bracket 3 can adjust its extension length, so it can lift the ends of injection rods of different lengths. The lifting platform 4 can move up and down to meet the lifting requirements of injection heads of different sizes. The support frame 1, telescopic bracket 3 and lifting platform 4 are all provided with several sets of bolt holes. The fixed base plate 21 of the directional wheel set 2 is connected to the above three parts by bolts. The above structure allows the directional wheel sets 2 at the three locations to be connected to different bolt holes, thereby realizing the adjustment of the position of the directional wheel set 2 to change the spacing between the two rollers 23 in the directional wheel set 2 to fit injection rods of different diameters.

[0035] The telescopic bracket 3 includes a C-shaped telescopic frame 31 that is slidably disposed in a groove, on which a set of directional wheels 2 are installed. Since the C-shaped telescopic frame 31 can slide inward and outward, its outward extension length can be adjusted so that it can support the ends of the injection rods of different lengths.

[0036] When the height of the platform 44 needs to be adjusted, the turntable 46 is rotated by the pivot 47, which in turn drives the screw jack 45 to lift or lower the platform 44, thereby driving the directional wheel set 2 on it to move and support the injection heads of different sizes.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
