Description

Technical Field

[0001] This utility model relates to the field of machine tool structure technology, and in particular to a high-efficiency mold processing machine tool. Background Technology

[0002] Machine tools are machines used to manufacture machines; they are also called machine tools or machine tools, and are commonly referred to simply as machine tools. They are generally classified into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools, among others. Modern mechanical manufacturing employs many methods for processing mechanical parts: in addition to cutting, there are casting, forging, welding, stamping, and extrusion. However, parts requiring high precision and fine surface roughness generally require final machining on machine tools using cutting methods.

[0003] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts.

[0004] Existing patent CN202022819343.4 discloses a mold processing work platform that is easy to adjust, including a mounting box. Support columns are fixedly connected to the four corners of the bottom of the mounting box. Movable plates are fixedly connected to the bottom of the support columns. A support sleeve is fitted on the surface of the movable plate. A spring is fixedly connected to the bottom of the support sleeve. The top of the spring is fixedly connected to the movable plate.

[0005] This mold processing platform, through the coordinated use of its components, offers the advantage of easy adjustment, solving the problem of inconvenient mold adjustment on traditional mold processing worktables. Previously, molds often needed to be removed for adjustment and then repositioned, increasing workload and reducing processing efficiency. However, limitations remain, such as limited adjustment height and the need for manual adjustment of certain structures, like the turntable, resulting in low overall efficiency.

[0006] Existing patent CN116038354B discloses a CNC machine tool for combined turning, grinding, and milling. A drilling tool is inserted into one side of the drive shaft head, and a linkage machining mechanism is set on one side of the outer wall of the drilling tool. The linkage machining component includes a milling cutter on one side of the outer wall of the drilling tool and a grinding tool on the other side of the outer wall of the drilling tool. This allows for large-area milling and grinding operations on the workpiece without the need for tool changing. However, the relative positions of the milling cutter and the grinding tool in this patent cannot be changed, which significantly limits the machining capabilities.

[0007] Therefore, most mold processing machine tools currently suffer from low processing efficiency. Utility Model Content

[0040] Similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] Example 1

[0042] A high-efficiency mold processing machine tool, such as Figure 1 As shown, it includes a mold fixing structure and a lifting mechanism located at the lower part of the housing, and a processing mechanism located at the upper part of the housing. The processing mechanism is located above the mold fixing structure, and the lifting mechanism supports and adjusts the lifting of the mold fixing structure to adjust the distance between the mold and the processing mechanism.

[0043] The lifting mechanism includes a vertically arranged telescopic hydraulic cylinder 1. The lower part of the telescopic hydraulic cylinder 1 is fixedly connected to the housing, and one end is fixedly connected to the mold fixing structure. In this embodiment, two telescopic hydraulic cylinders 1 are provided, symmetrically arranged on both sides of the mold fixing structure. A shock absorption mechanism is provided between the two telescopic hydraulic cylinders 1, including a spring 2 and a damper 3, with the spring 2 sleeved on the outside of the damper 3.

[0044] The mold fixing structure includes a circular platform 4, comprising an annular fixing part 401 and a rotating part 402 inside the annular fixing part 401. A bearing is located at the center of the rotating part 402. A rotating mechanism is mounted on the platform 4, comprising a bevel gear disc 5 and a bevel gear 6. The bevel gear disc 5 is coaxially fixed to the lower surface of the rotating part 402. A motor that drives the bevel gear 6 is mounted on a support below the platform 4. The rotating mechanism drives the rotating part 402 to rotate, and the rotating part 402 drives the fixing part 401 to rotate synchronously. The rotating part 402 and the fixing part 401 are an integral structure.

[0045] The bevel gear disc 5 has a through hole in its center. One end of the damper 3 passes through the through hole and is rotatably connected to the rotating part 402 via a bearing. The other end of the damper 3 is fixedly connected to the housing. The damper 3 is a telescopic structure and moves under the drive of the telescopic hydraulic cylinder 1.

[0046] The upper surface of platform 4 is equipped with several fixing mechanisms for fixing molds. Each fixing mechanism includes a fixing plate 7, which is vertically and fixedly connected to platform 4. An electric telescopic rod 8 is installed inside the fixing plate 7 and connected to an L-shaped plate 9. A threaded rod 10 is threaded through the top of the L-shaped plate 9, and the L-shaped plate 9 is threadedly connected to the threaded rod 10. A pressure plate 11 is movably connected to the bottom of the threaded rod 10. The connection between the threaded rod 10 and the pressure plate 11 is movably connected by a bearing, which facilitates the rotation of the threaded rod 10.

[0047] The bottom of the L-shaped plate 9 contacts the upper surface of the platform 4. A friction pad is fixedly connected to the bottom of the pressure plate 11. The friction pad increases the friction between the pressure plate 11 and the mold, facilitating mold positioning. The electric telescopic rod 8 is activated to extend and retract, causing the L-shaped plate 9 to move laterally, bringing it into contact with the side wall of the mold for initial fixation.

[0048] A geared motor 12 is fixedly connected to the top of the threaded rod 10. The geared motor 12 drives the threaded rod 10 to rotate, and the threaded rod 10 drives the pressure plate 11 to move up and down, so that the friction pad at the bottom of the pressure plate 11 contacts the mold and fixes the mold.

[0049] The electric telescopic rods 8 of each fixed mechanism are connected in parallel to the same power source to control each set of electric telescopic rods 8. The geared motors 12 of each fixed mechanism are connected to the same controller, which can control each set of moving components individually or simultaneously, using existing control methods.

[0050] The processing mechanism includes a rotating disk 13, which is rotatably connected to the housing via a bearing 3. A rotating mechanism 2 is connected to the lower surface of the rotating disk 13. The rotating mechanism 2 includes a bevel gear disk 2 14 and a bevel gear 2 15. The bevel gear disk 2 14 is coaxially fixed on the rotating disk 13. A motor 2 that drives the bevel gear 2 15 to rotate is provided on a bracket 2 on the housing.

[0051] A mounting bracket 16 is fixedly provided below the rotating disk 13. In this embodiment, six mounting brackets 16 are arranged in a circular array, with one mounting bracket 16 located at the center of the circle. A base 17 is provided below the mounting brackets 16, and the structure of the base 17 is as follows: Figure 2 As shown, the chassis 17 is a regular hexagon, and the diameter of the inscribed circle of the chassis 17 is larger than the diameter of the circle formed by the mounting bracket 16. In fact, the chassis 17 is a regular hexagonal disk shape, and the underlying machining components are not visible in its top view. This is to better illustrate the structure. Figure 2 The location of the processing components is shown in the diagram.

[0052] A groove 18 is formed on the chassis 17 from the midpoint of the side of a regular hexagon to the center of its inscribed circle. Above the groove 18 is a moving component for controlling the movement of the processing component, which includes a motor and a ball screw 19. The slider 20 on the ball screw 19 is connected to the processing component through the groove 18.

[0053] Each set of three moving components has three motors connected to a controller. The controller can control each set of moving components individually or simultaneously, using existing control methods. To determine whether the three motors of each set of moving components are moving synchronously, the signal from each motor can be sent to six high-speed input ports of a PLC for real-time monitoring and comparison. The synchronization of the motors is monitored by checking for consistency.

[0054] Processing components such as Figure 3 As shown, it includes a mounting plate 21, which is vertically arranged. The mounting plate 21 is fixedly connected to the slider 20. As the moving component drives the slider 20 to move, the mounting plate 21 also moves accordingly. The width of the slide groove 18 is smaller than the width of the mounting plate 21, and the slide groove 18 plays a limiting role for the mounting plate 21.

[0055] A lifting plate 22 is provided on the side of the mounting plate 21, and a lifting structure is provided on the mounting plate 21 to drive the lifting plate 22 to rise and fall. The lifting structure includes a second ball screw 23, the two ends of which are fixedly connected to the mounting plate 21. A fourth motor is provided on the mounting plate 21 to drive the second ball screw 23 to rotate, and the lifting plate 22 is slidably connected to the second ball screw 23. Under the action of the fourth motor, the second ball screw 23 drives the lifting plate 22 to rise and fall, thereby bringing the cutter head assembly 24 close to the mold to process the mold.

[0056] A sliding plate 25 is provided on the side of the lifting plate 22, and a lifting element is provided on the lifting plate 22 to drive the sliding plate 25 to rise and fall. The lifting element is a cylinder 26, which is fixed to the lifting plate 22. The telescopic rod of the cylinder 26 is fixedly connected to the sliding plate 25. Vertical guide rails are provided on the lifting plate 22, located on both sides of the cylinder 26, and guide grooves adapted to the guide rails are provided on the sliding plate 25. The extension and retraction of the cylinder 26 drives the cutter head assembly 24 to rise or fall, thereby performing deep processing on the mold surface. The cutter head assembly 24 is fixed to the sliding plate 25.

[0057] Example 2

[0058] The high-efficiency mold processing machine tool processing method in Example 1 can use multiple cutting heads to process the mold simultaneously, including the following steps:

[0059] S1. Place the mold to be processed on the platform 4, start the electric telescopic rod 8, the electric telescopic rod 8 drives the L-shaped plate 9 to move towards the mold until it contacts the side wall of the mold; start the reduction motor 12, the reduction motor 12 drives the pressure plate 11 to move towards the mold until the friction pad contacts the mold, so that the mold is completely fixed.

[0060] S2. Start the telescopic hydraulic cylinder 1 to move the platform 4 toward the processing mechanism, so that the mold is close to the processing mechanism.

[0061] S3. Start the rotating mechanism one and adjust the position of the mold corresponding to the different cutter head assemblies 24. Or start the motor two and adjust the cutter head assembly 24 to the position corresponding to the mold.

[0062] S4. Start the cutter head assembly 24, and the cutter head rotates; start the cylinder 26, and the cylinder 26 drives the cutter head assembly 24 to rise and fall; start the third motor, and the third motor drives the cutter head assembly 24 to move laterally; start the second motor, and the second motor drives the cutter head assembly 24 to perform circular motion; start the first rotating mechanism, and the mold rotates, adjusting the position of the corresponding cutter head assembly 24.

[0063] S5. Through the coordination between the control methods of the cutting head assembly 24 and the mold in steps S2 to S4, the mold can be processed at different positions and synchronously processed in a circumferential array.

[0064] Therefore, this utility model employs a high-efficiency mold processing machine tool, using a telescopic hydraulic cylinder combined with a spring damper for shock absorption to achieve mold height adjustment, making the adjustment process more stable and forming the basis for synchronous height adjustment and mold fixation. A geared motor drives a threaded rod to move the pressure plate up and down, which is more efficient than existing manual rotation adjustment and also allows for synchronization of adjustments between fixed components and with height adjustment. A horizontal ball screw is used to adjust the horizontal position of the processing mechanism, and a chassis is provided to make the movement process more stable. The position of each processing mechanism can be controlled independently, allowing for more precise simultaneous processing of the mold by multiple cutter assemblies, effectively improving mold processing efficiency. The cutter heads of the processing mechanism can be set to different cutter heads, avoiding tool changes during idle strokes, resulting in high tool changing efficiency and further improving mold processing efficiency.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
