Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, and in particular to an anti-vibration milling machine for precision mold manufacturing. Background Technology

[0002] Precision molds are specialized tools used to manufacture high-precision, complex-shaped parts, encompassing various types such as injection molding, stamping, and die casting. They not only achieve micron-level dimensional accuracy, meeting the extremely high precision requirements of industries like aerospace and optical instruments, but also support innovative designs through the forming of complex structures such as three-dimensional curved surfaces and holes, such as mobile phone cases and precision mechanical parts. However, in precision mold manufacturing, milling machines are the core equipment. A milling machine is a machine tool that processes workpieces by rotating a milling cutter, primarily used for machining planes, grooves, gears, threads, and complex curved surfaces. Its machining methods include milling, drilling, and boring, and it is suitable for precision machining of various materials (such as metals, plastics, and composite materials). Through high-speed milling technology, it can efficiently machine complex mold cavities such as three-dimensional curved surfaces and concave-convex structures, replacing traditional manual mold repair.

[0003] An existing patent (application number 202122963119.7) discloses a high-efficiency anti-vibration milling machine for precision mold manufacturing, relating to the field of mold manufacturing technology. It includes a worktable with a main body at its top and vibration damping components on both sides of its bottom. This invention utilizes a telescopic component and rollers. When the motor operates, its output drives a screw to rotate. Since the screw is threadedly connected to a threaded plate, and the threaded plate is slidably connected to the movable groove via a limiting groove and a limiting plate, the threaded plate causes the first fixed seat to move horizontally. Because the screw's helix direction is opposite, the two sets of threaded plates move in opposite directions. The second horizontal plate is rotatably connected to the threaded plate via the first fixed seat, a connecting plate, and a first pin, and to the first horizontal plate via the second fixed seat and a second pin. This allows the rollers to gradually move downwards as both sets of threaded plates move outwards.

[0004] Furthermore, the aforementioned patent states that "most milling machines are bulky, occupy a large area, are inconvenient to move, and have poor vibration resistance, making them susceptible to their own vibration and environmental vibration, which leads to a decrease in machining accuracy and fails to meet the needs of today's industry and market."

[0005] In summary, existing milling machines generate vibration and sway during machining, which affects the stability of the machining process. In addition, milling machines lack adequate protective structures, and some of the chips generated during machining can fly forward and onto the workers, posing a certain safety risk. Utility Model Content

[0006] Based on this, it is necessary to address the technical issues that milling machines generate vibrations and swaying during machining, which affect machining stability. In addition, milling machines lack adequate protective structures, and some chips generated during machining can fly forward and hit workers, posing a certain safety risk. Therefore, a vibration-resistant milling machine for precision mold manufacturing should be provided.

[0007] An anti-vibration milling machine for precision mold manufacturing includes a milling machine bed. Two slots are formed at the front upper part of the milling machine bed, and a protective device is engaged in both slots. A milling machine body is mounted at the rear upper part of the milling machine bed. A weighted base is fixedly mounted at the middle of the left and right ends of the milling machine bed, and a clamping device is fixedly mounted on the upper end of each of the two weighted bases. The clamping device includes a fixed seat and a clamping plate. An electric telescopic rod is inserted and fixedly mounted on the right end of the fixed seat, and a connecting seat is fixedly mounted on the right end of the clamping plate. A fixing bolt is mounted at the front end of the connecting seat. The protective device includes a protective frame. An upper baffle is fixedly mounted at the front upper part of the protective frame. Handles are fixedly mounted at the middle of the left and right ends of the protective frame. An observation window is inserted and fixedly mounted at the front end of the protective frame. Locking blocks are fixedly mounted on the lower left and lower right ends of the protective frame.

[0008] In one embodiment, the clamping plate is fixedly mounted on the output end of the electric telescopic rod via a connecting seat, and the fixing seat is fixedly mounted on the upper middle part of the weighted base.

[0009] Before use, the electric telescopic rod needs to be connected to an external power source. By pushing the clamping plate on its output end, the two clamping plates can move closer to each other to clamp the workpiece to be processed. In addition, when it is necessary to clamp different types of workpieces, the connecting seat and clamping plate can be removed by loosening the fixing bolts, so that the corresponding clamping tool can be replaced to clamp different types of workpieces, thereby improving the practicality of the device.

[0010] In one embodiment, the protective frame is snapped onto the front upper part of the milling machine bed by a locking block.

[0011] After the workpiece is clamped and before grinding, the protective frame on the protective device is snapped into two slots on the milling machine bed by the clip blocks. Through the design of the protective frame and its upper baffle, the chips generated during processing can be blocked, preventing the chips from flying forward to the workers. Moreover, the installation and disassembly of the protective frame is also relatively convenient due to the snap-fit ​​installation method.

[0012] In one embodiment, a worktable is fixedly installed at the middle of the upper part of the milling machine bed, and a buffer pad is fixedly installed at the lower end of the milling machine bed.

[0013] The milling machine bed is made of artificial marble, which has a low coefficient of thermal expansion. Through resin and mineral particle composite curing, the material has high rigidity. Under long-term load, its plastic deformation is less than that of cast iron beds by 30%. The internal multiphase structure can absorb more than 60% of vibration energy, suppressing high-frequency resonance between the spindle and the tool during machining and reducing surface roughness. In addition, a buffer pad is set at the lower end of the milling machine bed for further cushioning. At the same time, weighted bases are added to both ends of the milling machine bed. By reasonably adding weight to the bed base, the inertia is increased to suppress vibration.

[0014] In one embodiment, the upper baffle is inclined at a 45-degree angle, and there is a gap between the upper baffle and the milling machine body.

[0015] The upper baffle is designed with a 45-degree angle to further shield the flying debris generated during processing.

[0016] In one embodiment, the shape and size of the card block are adapted to the card slot, and the card block and the card slot are in sliding engagement.

[0017] In one embodiment, the cushioning pad is made of rubber; the milling machine bed is made of artificial marble.

[0018] In one embodiment, the protective frame is a U-shaped plate structure, and the position of the milling machine body is adapted to the clamping device.

[0019] In one embodiment, the handle is a U-shaped plate structure, and the two handles are symmetrically arranged on the protective frame.

[0020] In one embodiment, the lower end of the weighted base is flush with the lower end of the cushioning pad.

[0021] The aforementioned anti-vibration milling machine for precision mold manufacturing uses an electric telescopic rod on the clamping device to push the clamping plate on its output end, allowing the two clamping plates to come closer together and clamp the workpiece to be processed. Furthermore, when different types of workpieces need to be clamped, the connecting seat and clamping plate can be removed by loosening the fixing bolts, allowing for the replacement of the corresponding clamping tool, thus improving the practicality of the device. After the workpiece is clamped but before grinding, the protective frame on the protective device is engaged with two slots on the milling machine bed by a locking block. The design of the protective frame and its upper baffle effectively blocks the chips generated during processing, preventing them from flying forward to the operator. Moreover, the installation and removal of the protective frame are relatively convenient. The aforementioned anti-vibration milling machine for precision mold manufacturing uses artificial marble as the material for its machine bed. This material has a low coefficient of thermal expansion, is cured by combining resin and mineral particles, and has high rigidity. Under long-term load, its plastic deformation is less than that of a cast iron machine bed by 30%. Its internal multiphase structure can absorb more than 60% of vibration energy, suppressing high-frequency resonance between the spindle and the cutting tool during machining and reducing surface roughness. In addition, a buffer pad is provided at the lower end of the machine bed for further cushioning. At the same time, weighted bases are added to both ends of the machine bed. By reasonably increasing the weight of the machine bed base, the inertia is increased to suppress vibration. Attached Figure Description

[0031] Please refer to the following: Figures 1 to 4 This utility model provides a vibration-resistant milling machine for precision mold manufacturing, including a milling machine bed 1. Two slots 6 are formed at the front upper part of the milling machine bed 1, and a protective device 3 is engaged in both slots 6. A milling machine body 4 is mounted at the rear upper part of the milling machine bed 1. A weighted base 5 is fixedly mounted at the middle of both the left and right ends of the milling machine bed 1. A clamping device 2 is fixedly mounted on the upper end of each of the two weighted bases 5. The clamping device 2 includes a fixed seat 20 and a clamping plate 21. The fixed seat 20 is located on the right... An electric telescopic rod 22 is fixedly installed at one end of the clamping plate 21, and a connecting seat 23 is fixedly installed at the right end of the clamping plate 21. A fixing bolt 24 is installed at the front end of the connecting seat 23. The protective device 3 includes a protective frame 30. An upper baffle 34 is fixedly installed at the front of the upper end of the protective frame 30. Handles 31 are fixedly installed at the middle of the left end and the middle of the right end of the protective frame 30. An observation window 33 is fixedly installed at the front end of the protective frame 30. A locking block 32 is fixedly installed at the left end and the right end of the lower end of the protective frame 30.

[0032] The clamping plate 21 is fixedly installed on the output end of the electric telescopic rod 22 via the connecting seat 23, and the fixing seat 20 is fixedly installed on the upper middle part of the weighted base 5.

[0033] Before use, the electric telescopic rod 22 needs to be connected to an external power source. By pushing the clamping plate 21 on its output end through the electric telescopic rod 22, the two clamping plates 21 can move closer to each other, thereby clamping the workpiece to be processed. In addition, when it is necessary to clamp different types of workpieces, by loosening the fixing bolts 24, the connecting seat 23 and the clamping plate 21 can be removed, so that the corresponding clamping tool can be replaced to clamp different types of workpieces, thereby improving the practicality of the device.

[0034] The protective frame 30 is secured to the front of the upper end of the milling machine bed 1 by a locking block 32; the handle 31 is a "U"-shaped plate structure, and two handles 31 are symmetrically arranged on the protective frame 30; the protective frame 30 is a "U"-shaped plate structure, and the position of the milling machine body 4 is adapted to the clamping device 2; the shape and size of the locking block 32 are adapted to the slot 6, and the locking block 32 and the slot 6 slide together.

[0035] After the workpiece is clamped and before grinding, the protective frame 30 on the protective device 3 is snapped into the two slots 6 on the milling machine bed 1 by the snap-fit ​​block 32. Through the design of the protective frame 30 and the upper baffle 34 on it, the chips generated during processing can be blocked, preventing the chips from flying forward to the workers. Moreover, the installation and disassembly of the protective frame 30 are also relatively convenient due to the snap-fit ​​installation method.

[0036] A worktable 40 is fixedly installed in the middle of the upper end of the milling machine bed 1, and a buffer pad 41 is fixedly installed in the lower end of the milling machine bed 1; the lower end of the weight base 5 is flush with the lower end of the buffer pad 41; the buffer pad 41 is made of rubber; the milling machine bed 1 is made of artificial marble.

[0037] The milling machine bed 1 is made of artificial marble, which has a low coefficient of thermal expansion. It is cured by composite curing of resin and mineral particles, resulting in high material rigidity. Under long-term load, its plastic deformation is less than that of cast iron beds by 30%. Its internal multiphase structure can absorb more than 60% of vibration energy, suppressing high-frequency resonance between the spindle and the tool during machining and reducing surface roughness. In addition, a buffer pad 41 is provided at the lower end of the milling machine bed 1 to further buffer the vibration. At the same time, weighted bases 5 are added to both ends of the milling machine bed 1. By reasonably adding weight to the bed base, the inertia is increased to suppress vibration.

[0040] This utility model provides a vibration-resistant milling machine for precision mold manufacturing. First, the electric telescopic rod 22 on the clamping device 2 pushes the clamping plate 21 on its output end, so that the two clamping plates 21 can come closer to each other and clamp the workpiece to be processed. In addition, when different types of workpieces need to be clamped, the connecting seat 23 and the clamping plate 21 can be removed by loosening the fixing bolt 24, so that the corresponding clamping tool can be replaced, improving the practicality of the device. Next, the protective frame 30 on the protective device 3 is engaged by the locking block 32 into the two slots 6 on the milling machine bed 1. Through the design of the protective frame 30 and the upper baffle 34 on it, the chips generated during processing can be blocked, preventing the chips from flying forward to the workers. Moreover, the installation and removal of the protective frame 30 are also relatively convenient. Furthermore, the milling machine bed 1 is made of artificial marble and a buffer pad 41 is provided at the lower end, which can further buffer the impact. At the same time, a weighted base 5 is added to both ends of the milling machine bed 1. By reasonably adding weight to the bed base, the inertia is increased to suppress vibration.
