Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an adjustable magnesium alloy semi-solid injection unit base. Background Technology

[0002] Magnesium alloy semi-solid injection molding technology, with its advantages of high molding precision, uniform product performance, and high production efficiency, is widely used in the manufacturing of precision hardware, automotive parts, and electronic components. The alignment accuracy between the magnesium alloy semi-solid injection unit and the molding die directly determines the product molding quality. Traditional magnesium alloy semi-solid injection equipment bases are mostly fixed structures, capable only of simple forward and backward translation adjustments, unable to perform multi-dimensional adjustments such as angle rotation and height fine-tuning. In actual production, factors such as mold installation errors, equipment assembly deviations, and production vibrations can easily cause misalignment between the injection unit's outlet and the mold's inlet. Traditional bases cannot provide angle and height compensation adjustments, requiring repeated manual calibration and disassembly, resulting in extremely low adjustment efficiency, poor calibration accuracy, and severely impacting production cycle time and reducing product yield.

The lower base is equipped with a rotation drive assembly, which is connected to the upper base for driving the upper base to rotate horizontally relative to the lower base. An arc-shaped guide and limiting structure is matched between the upper base and the lower base to guide and limit the rotational movement of the upper base.

The upper base is equipped with a sliding guide assembly, and the magnesium alloy semi-solid injection unit is slidably mounted on the sliding guide assembly. A translation drive assembly is arranged between the frame and the magnesium alloy semi-solid injection unit.

[0005] Preferably, the rotary drive assembly includes a first hydraulic cylinder, which is fixedly mounted on the lower base. The telescopic end of the first hydraulic cylinder is hinged to the upper base for transmission.

[0007] Preferably, the lifting drive assembly includes at least one lifting cylinder, which is fixed at the edge of the lower base, and the lifting end of the lifting cylinder vertically penetrates the lower base and abuts against the bottom surface of the upper base.

[0008] Preferably, the magnesium alloy semi-solid injection unit includes a base and an injection device fixedly installed on the base. The base is connected to the sliding end of the sliding guide assembly. The base can slide synchronously with the sliding end, and the base drives the injection device to slide back and forth.

[0009] Further optimization involves the sliding guide assembly comprising two guide rails and multiple sliders.

The second hydraulic cylinders are arranged in the front-back direction. The fixed end of the second hydraulic cylinder is hinged to the base body, and the telescopic end of the second hydraulic cylinder is hinged to the molding die.

[0011] Further optimization involves the seat and the injection device being integrated or fixedly connected, with each slider corresponding to and connected to a seat, achieving multi-point uniform support.

[0012] Preferably, a wear-resistant lubrication support assembly is fitted between the mating surfaces of the upper base and the lower base.

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0022] This utility model provides an adjustable magnesium alloy semi-solid injection unit base, including a frame, on which a magnesium alloy semi-solid injection unit 1, a molding die 2, and a double-layer adjustable base 3 are mounted. Figure 1 As shown, the base 3 is divided into an upper base 31 and a lower base 32, which are arranged correspondingly. The magnesium alloy semi-solid injection unit 1 is installed on the upper surface of the upper base 31. The magnesium alloy semi-solid injection unit 1 and the molding die 2 are distributed and connected along the front and back direction of the upper base 31.

[0023] A rotating shaft 4 is installed through the center of the upper base 31 and the lower base 32, so that the upper base 31 can rotate relative to the center of the lower base 32. A rotation drive component 5 is provided at the front end of the lower base 32. The rotation drive component 5 is connected to the upper base 31 and is used to drive the upper base 31 to rotate horizontally around the rotating shaft 4. An arc-shaped guide and limit structure 6 is matched between the upper base 31 and the lower base 32 to guide and limit the rotation of the upper base 31, so that the rotation of the upper base 31 is more stable.

[0024] The lower base 32 is equipped with a lifting drive assembly 7. The drive end of the lifting drive assembly 7 abuts against the upper base 31 and is used to drive the upper base 31 to make vertical lifting movements relative to the lower base 32. The upper base 31 is provided with a sliding guide assembly 8, and the magnesium alloy semi-solid injection unit 1 is slidably connected to the upper base 31 through the sliding guide assembly 8; a translation drive assembly 9 is arranged between the frame and the magnesium alloy semi-solid injection unit 1, and the translation drive assembly 9 is used to drive the magnesium alloy semi-solid injection unit 1 to make a back-and-forth reciprocating sliding motion along the sliding guide assembly 8 so that the magnesium alloy semi-solid injection unit 1 can move closer to or away from the molding die 2.

[0025] Furthermore, the rotary drive assembly 5 includes a first hydraulic cylinder 51. The fixed end of the first hydraulic cylinder 51 is mounted on the lower base 32, and the telescopic end of the first hydraulic cylinder 51 is hinged to the side wall of the upper base 31. The telescopic end of the first hydraulic cylinder 51 extends and retracts in the left-right direction, used to drive the upper base 31 to rotate horizontally around the pivot 4. Figure 4As shown, the lower base 32 has an arc-shaped guide groove 61 with the rotating shaft 4 as the center. In this embodiment, there are two arc-shaped guide grooves 61, which are symmetrically distributed with the rotating shaft 4 as the center. The upper base 31 is fixedly connected to a guide post 62, which is inserted into the arc-shaped guide groove 61. When the upper base 31 rotates, the guide post 62 can slide along the arc-shaped guide groove 61, thus limiting and guiding the rotation stroke of the upper base 31, ensuring that the rotation angle of the upper base 31 is accurate and the operation is stable.

[0026] The lifting drive assembly 7 includes at least one lifting cylinder 71. In this embodiment, as shown... Figure 3 As shown, multiple lifting cylinders 71 are evenly spaced along the edge of the lower base 32. The lifting cylinders 71 are vertically arranged, and the fixed end of the lifting cylinder 71 is installed at the bottom edge of the lower base 32. The lifting end of the lifting cylinder 71 passes upward through the lower base 32 and tightly abuts against the bottom surface of the upper base 31. Through the extension and retraction of the lifting cylinder 71, the upper base 31 can be lifted to realize the lifting and lowering of the upper base 31. The upper base 31 drives the magnesium alloy semi-solid injection unit 1 to lift and lower as a whole, thereby completing the height fine adjustment to meet the docking requirements of molding dies 2 of different heights.

[0027] The magnesium alloy semi-solid injection unit 1 includes a base 11 and an injection device 12 fixedly installed on the base 11. The base 11 is fixedly connected to the sliding end of the sliding guide assembly 8. The base 11 can slide synchronously with the sliding end, and the base 11 drives the injection device 12 to slide back and forth.

[0028] Furthermore, the sliding guide assembly 8 includes a guide rail 81 and a slider 82. In this embodiment, there are two guide rails 81, which are symmetrically arranged on the left and right sides of the injection device 12 along the front-back direction of the top of the upper base 31. Multiple sliders 82 are installed on each guide rail 81 at intervals, and the sliders 82 slide in cooperation with the guide rail 81. The seat 11 of the injection unit is fixed on the top surface of the slider 82. The seat 11 is integrally formed or fixedly connected to the housing of the injection device 12. Each slider 82 is matched and connected to a seat 11 to achieve multi-point uniform support.

[0029] Furthermore, the translation drive assembly 9 consists of two second hydraulic cylinders 91, which are symmetrically arranged on the left and right sides of the injection equipment 12. The second hydraulic cylinders 91 are arranged in the front-back direction, with their fixed ends hinged to the seat body 11 and their telescopic ends hinged to the molding die 2. The second hydraulic cylinders 91 drive the seat body 11 and the injection equipment 12 to slide back and forth along the guide rail 81 to complete the injection docking and resetting actions.

[0030] Therefore, the symmetrical double second hydraulic cylinders 91 and double guide rails 81 combined with the multi-point slider 82 support structure make the injection unit move back and forth with uniform force and run smoothly without deviation or jamming. The stability of the equipment operation is greatly improved, which is suitable for the production needs of high-speed and high-precision semi-solid injection molding.

[0031] A wear-resistant and lubricating support assembly 10 is installed between the mating surfaces of the upper base 31 and the lower base 32. The wear-resistant and lubricating support assembly 10 is fixed on the upper base 31 or the lower base 32 to support and lubricate the relative moving contact surfaces of the upper base 31 and the lower base 32 to reduce friction and assist the rotation of the upper base 31.

[0032] Furthermore, the wear-resistant lubrication support assembly 10 includes a sliding friction block 101, an oil nozzle 102, and an oil groove 103. The upper base 31 or lower base 32 has a through hole penetrating the upper and lower end faces, and the sliding friction block 101 is embedded within the through hole. Figure 2 As shown, the top of the sliding friction block 101 passes through the through hole and is connected to the oil nozzle 102. The sliding friction block 101 is sandwiched between the upper base 31 and the lower base 32. Figure 5 As shown, an oil reservoir 103 is provided on the bottom end face of the sliding friction block 101. Its bottom end face abuts against the upper surface of the lower base 32 or the lower surface of the upper base 31. Lubricating oil is injected into the interior through the oil injection nozzle 102. The lubricating oil flows into the oil reservoir 103 and is retained. During the rotation of the upper base 31, the contact friction surfaces of the upper base 31 and the lower base 32 are continuously lubricated to reduce wear. At the same time, the sliding friction block 101 can bear part of the load and improve the structural stability of the base 3.

[0033] Therefore, by forming a continuous lubrication system through the grease nipple 102 and the bottom oil groove 103, the relative contact surfaces of the upper base 31 and the lower base 32 that rotate and rise and fall are lubricated for a long time, reducing mechanical wear, reducing the probability of equipment failure, and extending the service life of the equipment. At the same time, the sliding friction block 101 can play an auxiliary support role and improve the overall structural stability of the base 3.

[0034] When the equipment is working, the height of the magnesium alloy semi-solid injection unit 1 can be adjusted by lifting cylinder 71 according to the position deviation of molding mold 2, the horizontal angle of magnesium alloy semi-solid injection unit 1 can be adjusted by first hydraulic cylinder 51, and the magnesium alloy semi-solid injection unit 1 can be precisely pushed back and forth by second hydraulic cylinder 91. The multi-dimensional cooperation completes the precise docking of injection unit and molding mold 2. After docking, magnesium alloy semi-solid injection molding operation can be carried out. The whole process is convenient to adjust, highly accurate and stable in operation.

[0035] This utility model is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this utility model. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to this utility model falls within the protection scope of this utility model.
