Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing, and more specifically relates to a die-casting machine template milling device. Background Art

[0002] After a die-casting machine has been used for a long time, the middle plate will have problems such as depression and unevenness due to the long-term pressure of the mold on the middle plate, which directly affects the quality of the die-casting and wastes die-casting materials. After this problem occurs, the die-casting machine is generally disassembled and the first plate and the middle plate are moved to large-scale machine processing equipment for re-correction and milling, and then reinstalled and debugged. The steps are similar to reinstalling a new die-casting machine. Especially when dealing with the templates of medium and large die-casting machines (with a clamping force of more than 1000t), the weight of the middle plate or the first plate is about 10 tons. Disassembly and installation are particularly difficult, time-consuming, and costly, so many medium and large die-casting machines can only be produced with problems. Utility Model Content

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0036] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0037] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0038] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0039] The die-casting machine includes a front plate, a rear plate, and a middle plate disposed between the front plate and the rear plate. The front plate and the rear plate are connected by guide columns. During the operation of the mold, due to the support of the middle plate, the mold will not deform. However, due to the long-term pressure exerted by the mold on the middle plate, after long-term use of the die-casting machine, problems such as middle depression and unevenness of the middle plate will occur, directly affecting the quality of die-castings and wasting aluminum materials. After this problem occurs, generally, the die-casting machine is disassembled, and the front plate and the middle plate are transported to large machining equipment for re-machining and milling, and then reinstalled and debugged. The steps are similar to reinstalling a new die-casting machine. The disassembly and assembly processes are complex, time-consuming, and costly, causing many medium and large die-casting machines to operate with problems and making it difficult to ensure the quality of die-castings.

[0040] To solve the above technical problems, the present utility model proposes a die-casting machine template milling and flattening device 100. This device can be installed on the guide columns 300 of the die-casting machine. Without disassembling the front plate and the middle plate, it can trim and mill the template 400 of the die-casting machine, solving problems such as long time consumption and high cost for trimming the template 400 caused by disassembly and assembly. Among them, the template 400 can be the middle plate, the front plate, etc.

[0041] Now, the die-casting machine template milling and flattening device 100 provided by the embodiments of the present utility model will be described.

[0042] Please refer to Figures 1 to 3 , the die-casting machine template milling and flattening device 100 is installed on the guide columns 300 of the die-casting machine. When it is necessary to mill the template 400, the die-casting machine template 400 milling and flattening device is directly installed on the guide columns 300 and is disposed close to the machining surface to be processed of the template 400. In this way, there is no need to disassemble and assemble the die-casting machine, improving the trimming efficiency of the template 400 and reducing the trimming cost of the template 400.

[0043] The die-casting machine template milling and flattening device 100 includes a main shaft 10, a feed assembly 20, and a cutter 30.

[0044] The main shaft 10 can output a rotational motion. By the rotation of the main shaft 10, the cutter 30 is driven to rotate around the central axis of the main shaft 10 to mill the machining surface to be processed of the template 400.

[0045] The feed assembly 20 can output linear motion, drive the tool 30 to perform a feeding motion, and change the position of the tool 30, so as to mill the entire surface to be machined. Among them, the direction of the feeding motion of the tool 30 is parallel or nearly parallel to the surface to be machined of the template 400.

[0046] The tool 30 is used to mill the template 400. When the die-casting machine template milling and flattening device 100 is installed on the guide column 300, the milling surface of the tool 30 faces the surface to be machined of the template 400, and thus the surface to be machined can be milled.

[0047] When the template 400 needs to be trimmed, first install the die-casting machine template milling and flattening device 100 on the guide column 300. While the main shaft 10 outputs a rotational motion, the feed assembly 20 moves the tool 30 according to a preset setting to perform Archimedes spiral milling, gradually repairing the surface to be machined into a flat surface.

[0048] The die-casting machine template milling and flattening device 100 in the above embodiment includes a main shaft 10, a feed assembly 20, and a tool 30. The main shaft 10 can output a rotational motion to rotate the tool 30 to mill the template 400 flat. The feed assembly 20 can drive the tool 30 to approach or move away from the center of the template 400 to adjust the position of the tool 30. The die-casting machine template milling and flattening device 100 is installed on the guide column 300 of the die-casting machine, and the template 400 can be milled without disassembling the template 400, without disassembling and reinstalling the die-casting machine, and without readjusting the die-casting machine, solving the problems of complex disassembly and assembly, long time consumption, and high cost in milling the template 400.

[0049] In some embodiments of the present utility model, please refer to Figure 2 and Figure 3 , the main shaft 10 is configured to be connected to the guide column 300. The main shaft 10, the feed assembly 20, and the tool 30 are connected in sequence. The main shaft 10 is used to drive the feed assembly 20 and the tool 30 to rotate, and the feed assembly 20 is used to drive the tool 30 to perform linear motion. The housing part of the main shaft 10 is fixed to the guide column 300, so that the entire die-casting machine template milling and flattening device 100 is fixed to the guide column 300.

[0050] The main shaft 10, the feed assembly 20, and the tool 30 are connected in sequence. The feed assembly 20 only needs to drive the tool 30 to feed, and the load of the feed assembly 20 is small, and the motion is more stable.

[0051] In other embodiments of the present utility model, the feed assembly 20 is fixed to the guide column 300, and the feed assembly 20, the main shaft 10, and the tool 30 are connected in sequence. The power output end of the feed assembly 20 is connected to the main shaft 10, and the main shaft 10 is connected to the tool 30. In this embodiment, the main shaft 10 only needs to drive the tool 30 to rotate, and the load of the main shaft 10 is small. A main shaft 10 with a lower load-bearing capacity can be selected to reduce the part cost.

[0052] In some embodiments, referring to Figure 1 , the main shaft 10 is fixed to the guide column 300 through the cross beam 200. Specifically, the housing part of the main shaft 10 is fixed on the cross beam 200, and both ends of the cross beam 200 are respectively fixed on two adjacent guide columns 300. Through the setting of the cross beam 200, on the one hand, the connection between the die-casting machine template milling and flattening device 100 and the guide column 300 is made more stable, and on the other hand, the installation of the main shaft 10 is made more convenient.

[0053] In some embodiments, referring to Figure 2 and Figure 3 , the feeding assembly 20 includes a driver 21 capable of outputting rotational motion and a transmission assembly 22 capable of outputting linear motion. The driver 21 is connected to the main shaft 10. The power input end of the transmission assembly 22 is driven by the driver 21, and the power output end of the transmission assembly 22 is connected to the cutter 30. The housing part of the driver 21 can be fixedly connected to the main shaft 10, so that the entire transmission assembly 22 is fixed at the main shaft 10. The driver 21 is used to provide power, and the transmission assembly 22 is used to transmit power to the cutter 30. Specifically, the housing part of the driver 21 is connected to the main shaft 10. When the main shaft 20 works, it drives the entire feeding assembly 20 to rotate. When the driver 21 works, it outputs rotational motion, and the transmission assembly 22 converts the rotational motion into linear motion. The direction of the linear motion is the feeding direction of the cutter 30, driving the cutter 30 to achieve translational feeding.

[0054] By setting the transmission assembly 22 to change the form of power output, the cutter 30 can be driven to translate, and at the same time, the translational speed of the cutter 30 can be adjusted by reasonably designing the transmission ratio to match the rotational speed of the main shaft 10.

[0055] Optionally, the driver 21 is a motor, a motor, etc. capable of outputting rotational motion.

[0056] Optionally, referring to Figure 3 , the transmission assembly 22 includes a worm 221 driven by the driver 21 to rotate, a worm gear 222 meshing with the worm 221, a gear 223 synchronously moving with the worm gear 222, and a rack 224 meshing with the gear 223. The rack 224 is fixedly connected to the cutter 30. When the driver 21 works, it outputs rotational motion to drive the worm 221 to rotate. The worm gear 222 rotates under the driving action of the worm 221, and the gear 223 synchronously moves with the worm gear 222 to drive the rack 224 to move linearly.

[0057] The cooperation between the worm 221 and the worm wheel 222 enables the transmission assembly 22 to achieve a high transmission ratio with a relatively small volume, and the transmission is stable, with low noise and a reverse self-locking function. The cooperation between the gear 223 and the rack 224 can achieve the linear motion of the tool 30, and the transmission accuracy is relatively high, making the motion of the tool 30 more precise.

[0058] Optionally, the meshing teeth on the gear 223 and the rack 224 can be straight teeth or helical teeth.

[0059] Optionally, the transmission assembly 22 includes a lead screw driven to rotate by a driver 21, a nut threadedly connected to the lead screw, and a guiding structure for guiding the nut, and the tool 30 is fixedly connected to the nut. The driver 21 outputs a rotational motion to drive the lead screw to rotate, and the nut seat moves linearly along the axial direction of the lead screw, thereby driving the tool 30 to move linearly. In this embodiment, the transmission assembly 22 may further include a gear assembly to adjust the transmission ratio of the transmission assembly 22.

[0060] In some embodiments, please refer to Figures 3 to 5 , the feed assembly 20 further includes a first bearing 251 and a rotating shaft 253. The rotating shaft 253 is coaxially arranged with the main shaft 10. The outer ring of the first bearing 251 is fixedly connected to the main shaft 10, and the inner ring of the first bearing 251 is fixedly connected to the rotating shaft 253. Both the worm wheel 222 and the gear 223 are fixed to the rotating shaft 253. The rotating shaft 253 is connected to the end of the main shaft 10 through the first bearing 251, so that the rotating shaft 253 is installed at the end of the main shaft 10 and is relatively independent of the rotation of the main shaft 10. When the driver 21 operates, the worm 221 drives the worm wheel 222 to rotate. Since both the worm wheel 222 and the gear 223 are fixed to the rotating shaft 253, the rotating shaft 253 and the gear 223 also rotate synchronously. Under the rotational support of the first bearing 251, the rotation of the rotating shaft 253 does not affect the movement of the main shaft 10, that is, the movement of the transmission assembly 22 and the movement of the main shaft 10 do not interfere with each other. Since the feed assembly 20 is integrally assembled on the main shaft 10, the rotation of the main shaft 10 can drive the entire feed assembly 20 to rotate around an axis perpendicular to the milling surface, thereby driving the tool 30 to rotate in a plane substantially parallel to the surface to be machined; at the same time, the tool 30 can achieve linear motion under the drive of the feed assembly 20. Furthermore, through the cooperation of the main shaft 10 and the feed assembly 20, the tool 30 can perform rotational and linear motions.

[0061] By fixedly connecting the worm wheel 222 and the gear 223 through the rotating shaft 253, the synchronous movement of the worm wheel 222 and the gear 223 is achieved. The rotating shaft 253 is installed on the main shaft 10 through the first bearing 251, which not only provides an installation position for the rotating shaft 253 but also does not affect the rotation of the main shaft 10.

[0062] In some embodiments, please refer to Figures 4 to 6, the feed component 20 further includes a slide base 23 and a slide table 24 slidably connected to the slide base 23. The driver 21 is fixed to the slide base 23, the slide base 23 is fixed to the main shaft 10, and the rack 224 is fixed to the side of the slide table 24 facing the slide base 23. When the main shaft 10 rotates, both the slide base 23 and the slide table 24 rotate accordingly. The slide table 24 can move relative to the slide base 23 driven by the rack 224, and the movement of the rack 224 is synchronized with that of the slide table 24.

[0063] By providing the slide base 23 and the slide table 24, the movement of the rack 224 can be guided to make the movement of the rack 224 more stable. At the same time, the slide base 23 can provide protection and installation positions for structures such as the transmission component 22, and the slide table 24 is convenient for providing protection and installation positions for the rack 224.

[0064] In some embodiments, the driver 21 is fixed on the slide base 23. Specifically, the housing part of the driver 21 is fixed on the slide base 23, and the slide base 23 can provide an installation position for the driver 21.

[0065] In some embodiments, please refer to Figure 5 , the slide base 23 is fixedly connected to the main shaft 10. A flange is formed by radially extending outward at the end of the main shaft 10. The flange has mounting holes. The slide base 23 is fixed to each other through the mounting holes on the flange by means of threads and other connecting parts. Connecting the main shaft 10 and the slide base 23 through the flange can make the connection between the main shaft 10 and the slide base 23 more stable.

[0066] In some embodiments, please refer to Figures 3 to 5 , the worm 221, the worm gear 222 and the gear 223 are all arranged inside the slide base 23. The slide base 23 can protect the transmission component 22 and also provide support for the transmission component 22, making the transmission component 22 work more stably.

[0067] In some embodiments, please refer to Figure 5 , a first accommodation cavity 231 is formed on the side of the slide base 23 facing the main shaft 10, and a second accommodation cavity 232 is formed on the side of the slide base 23 facing away from the main shaft 10. The worm gear 222 is arranged in the first accommodation cavity 231, and the gear 223 is arranged in the second accommodation cavity 232. The first accommodation cavity 231 and the second accommodation cavity 232 are respectively arranged on opposite sides of the slide base 23. The first accommodation cavity 231 can be understood as a groove formed on the side of the slide base 23 facing the main shaft 10, and the second accommodation cavity 232 can be understood as a groove formed on the side of the slide base 23 facing away from the main shaft 10.

[0068] By respectively arranging the first accommodation cavity 231 and the second accommodation cavity 232 on opposite sides of the slide base 23, the worm gear 222 and the gear 223 can be conveniently installed inside the slide base 23, and the worm gear 222 and the gear 223 are protected by the slide base 23.

[0069] Optionally, refer to Figure 5 , a communication hole communicating the first accommodation cavity 231 and the second accommodation cavity 232 is formed in the sliding seat 23. The communication hole allows the rotating shaft 253 to pass through. A part of the rotating shaft 253 is located in the first accommodation cavity 231, and a part is located in the second accommodation cavity 232, so that the worm gear 222 and the gear 223 are respectively installed in the first accommodation cavity 231 and the second accommodation cavity 232.

[0070] Optionally, refer to Figure 5 , the feeding assembly 20 further includes a second bearing 252. The second bearing 252 is used to support the rotating shaft 253. The inner ring of the second bearing 252 is fixedly connected to the rotating shaft 253, and the outer ring of the second bearing 252 is fixed to the sliding seat 23. By providing the second bearing 252, the rotation of the rotating shaft 253 can be made more stable.

[0071] Optionally, both the first bearing 251 and the second bearing 252 support the rotating shaft 253. The first bearing 251 is installed on the main shaft 10 to support one end of the rotating shaft 253, and the second bearing 252 is installed on the sliding seat 23 to support the other end of the rotating shaft 253. The rotating shaft 253 has at least two support positions, reducing the radial runout of the rotating shaft 253.

[0072] Among them, the second bearing 252 can be arranged between the worm gear 222 and the gear 223, or arranged on the side of the gear 223 away from the worm gear 222.

[0073] In some embodiments of the present invention, refer to Figure 2 and Figure 6 , the sliding seat 23 has a first guiding portion, and the sliding table 24 has a second guiding portion. The first guiding portion and the second guiding portion are mutually engaged, and an installation space 242 for accommodating the rack 224 is formed between the first guiding portion and the second guiding portion. The mutual engagement of the first guiding portion and the second guiding portion makes the sliding of the sliding table 24 relative to the sliding seat 23 more stable, and further makes the feeding movement of the cutter 30 more stable. After the first guiding portion and the second guiding portion are mutually engaged, they are not completely adapted to each other. An installation space 242 for installing the rack 224 is reserved between the first guiding portion and the second guiding portion. The rack 224 is fixed to the second guiding portion of the sliding table 24 and is closer to the sliding seat 23, facilitating the mutual meshing of the rack 224 and the gear 223.

[0074] By fixing the rack 224 on the second guiding portion and arranging it at the joint of the first guiding portion and the second guiding portion, the structure of the milling and planing equipment can be made more compact, and the structural layout of the rack 224 and the gear 223 can be made more convenient.

[0075] In other embodiments, the rack 224 can also be fixed on other surfaces of the sliding table 24 (except the surface provided with the second guiding portion).

[0076] In some embodiments, the first guiding portion is a dovetail groove 233, and the second guiding portion is a dovetail block 241. An installation space 242 is formed by the inner wall of the dovetail groove 233 being recessed; alternatively, the installation space 242 is provided on the dovetail block 241; alternatively, a first notch is formed by the inner wall of the dovetail groove 233 being recessed, and a second notch is provided on the dovetail block 241, and the first notch and the second notch together form the installation space 242. In other embodiments, the first guiding portion is a dovetail block 241, and the second guiding portion is a dovetail groove 233. The formation of the installation space 242 can be referred to the above, and will not be elaborated here.

[0077] In some embodiments of the present utility model, the milling surface of the cutter 30 is parallel to the surface to be machined of the template 400. After the surface to be machined is milled by the cutter 30, it can be re-trimmed into a flat surface.

[0078] In some embodiments of the present utility model, the distance between the milling surface of the cutter 30 and the surface to be machined of the template 400 gradually decreases from the center to the edge of the template 400. After the template 400 is used under pressure for a long time, the middle part of the template 400 is recessed and the periphery is convex. The milling surface of the cutter 30 and the surface to be machined are arranged at an angle, so that the cutting amount in the middle part of the template 400 is small and the cutting amount around the template 400 is large, so as to compensate for the depression in the middle part of the template 400. The milling surface of the cutter 30 and the surface to be machined are arranged at an angle, which can reduce the overall cutting amount of the template 400 and improve the machining efficiency of trimming the template 400.

[0079] By adjusting the angle of the milling surface of the cutter 30, the cutting amount in the middle part and the edge of the template 400 can be changed, the overall cutting amount of the template 400 can be reduced, and it is applicable to trimming templates 400 with different damage degrees.

[0080] In some embodiments of the present utility model, please refer to Figure 2 , the die-casting machine template milling flat device 100 further includes a power supply and a controller. The power supply supplies power to the feeding assembly 20, and the controller communicates wirelessly with the control terminal. The power supply provides energy for the feeding assembly 20, so that the feeding assembly 20 outputs a linear motion. The controller is electrically connected to both the power supply and the feeding assembly 20. The controller can control the start and stop of the feeding assembly 20, the moving speed of the cutter 30, etc. Specifically, the control terminal issues an instruction, and the instruction includes the start and stop of the feeding assembly 20, the rotation speed of the driver 21, the working time of the driver 21, etc. The controller controls the driver 21 to execute the above instructions.

[0081] The controller communicates wirelessly with the control terminal, and can remotely control the feeding assembly 20. There is no need to design a cable to connect to the controller, which reduces the cables of the milling flat device and improves the operation safety.

[0082] In some embodiments, the control terminal can be a computer, a tablet, an operation panel, etc.

[0083] In some embodiments, the power supply is a charging power supply.

[0084] In some embodiments, both the power supply and the controller are disposed inside the control box 26. The control box 26 can protect both the power supply and the controller, and can also place the cables inside the control box 26.

[0085] Optionally, the control box 26 is fixed to the slide base 23. When the main shaft 10 is operating, the control box 26 rotates together with the slide base 23 to prevent the connection cable between the controller and the feed assembly 20 from being pulled.

[0086] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
