Description

Technical Field

[0001] This utility model relates to the field of mold processing equipment technology, and in particular to a vertical milling machine for processing mold surfaces. Background Technology

[0002] Molds are an indispensable basic process equipment in modern industrial production, and the precision and quality of their surfaces directly determine the quality of the final product. Vertical milling machines are commonly used equipment in mold manufacturing to process mold surfaces, cutting the workpiece with a milling cutter to obtain the required shape and size.

[0003] When machining molds with complex curved or inclined surfaces, simply relying on the movement of the milling cutter in a standard coordinate system is far from sufficient. In order for the tool to accurately cut to specific positions on the surface, it is usually necessary to adjust the mold workpiece itself to a suitable machining posture, that is, to adjust the angle of the workpiece relative to the tool.

[0004] Currently, this type of angle adjustment is typically achieved by attaching accessories such as a tilting table or a manual indexing plate to the milling machine's worktable. However, when a complex angle adjustment requiring both longitudinal tilting and lateral rotation is needed, the operator often has to combine multiple accessories or perform multiple tedious manual clamping and calibrations. This step-by-step, non-integrated adjustment method not only involves a complex operating procedure and consumes a significant amount of auxiliary time, but also allows for the accumulation of errors from multiple clamping and positioning operations, affecting the final machining accuracy and making it difficult to meet the demands of high-efficiency, high-precision machining of complex mold surfaces.

[0005] Therefore, this utility model proposes a vertical milling machine for machining mold surfaces to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a vertical milling machine for mold surface processing, which aims to improve the problem that existing equipment used for mold surface processing is difficult to conveniently achieve multi-degree-of-freedom compound angle adjustment when positioning the workpiece, resulting in low efficiency in processing complex curved surfaces.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a vertical milling machine for machining mold surfaces, comprising a fixed frame, a slide rail fixedly connected to the fixed frame, a cylinder cutting blade slidably connected to the slide rail; and a rotating assembly; The rotating assembly includes a fixed plate fixedly connected to the fixed frame. The rotating assembly also includes a fixed block, a first motor, a threaded rod, a second support frame, a gear, a guide plate, a cylinder, and a limiting plate. The first motor is fixedly connected to the fixed plate, and the threaded rod is drive-connected to the first motor. The second support frame is rotatably connected to the fixed plate, and the gear is fixedly connected to the second support frame. The threaded rod and the gear form a worm gear transmission mechanism. The guide plate is fixedly connected to the top of the second support frame. The first support frame is fixedly connected to the bottom of the second support frame, and the second motor is fixedly connected to the first support frame. The cylinder is mounted on the guide plate, and the limiting plate is connected to the piston rod end of the cylinder and slides along the guide plate.

[0008] Preferably, the vertical milling machine for machining mold surfaces further includes a circulation component, which includes a water pump and a water pipe connecting the water pump to the machining area of ​​the cylinder cutting tool.

[0009] Preferably, the circulation component further includes a collection frame located below the rotation component.

[0010] Preferably, the inside of the collection frame is provided with a filter screen for filtering the coolant.

[0011] Preferably, the circulation assembly further includes a filter cartridge located between the collection frame and the water pump inlet.

[0012] Preferably, the top opening of the collection frame is covered with a cover plate.

[0013] Preferably, a sealing strip is provided between the contact edge of the cover plate and the collection frame.

[0014] Preferably, the circulation component further includes a support block, and the water pump is fixedly mounted on the support block.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting up a rotating assembly integrating a first motor and a second motor, uses the first motor to achieve longitudinal angle adjustment of the mold via a threaded rod and gear transmission, and the second motor to directly drive the support structure to achieve lateral angle adjustment of the mold. This solves the problem in the prior art that it is difficult to achieve flexible and multi-dimensional composite angle adjustment when positioning the mold surface, resulting in low efficiency and difficulty in guaranteeing accuracy when processing complex curved surfaces. It achieves the effect of convenient and accurate longitudinal and lateral composite posture adjustment of the mold, significantly improving the flexibility of processing complex surfaces.

[0016] 2. This utility model, by setting up a circulation assembly consisting of a water pump, water pipe, collection frame, filter screen and filter cylinder, cools the cutting area while processing, and collects, filters and recycles the used coolant. This solves the problems of tool wear and affected processing quality caused by cutting heat during processing, as well as the waste and increased cost caused by single use of coolant. It achieves effective cooling of the processing area, while realizing the filtration and recycling of coolant, thereby ensuring processing quality, extending tool life and reducing production costs.

[0019] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1-6 This utility model provides an embodiment of a vertical milling machine for machining mold surfaces, including a fixed frame 1, which serves as the mounting base for the entire device, providing stable installation and support for the main body of the equipment. A slide rail 2 is fixedly connected to the fixed frame 1, and a cylinder cutting blade 3 is slidably connected to the slide rail 2. The cylinder cutting blade 3 can move smoothly along a preset trajectory of the slide rail 2 to perform cutting machining on the mold surface. The vertical milling machine for machining mold surfaces also includes a rotating component 4, which is mounted on the fixed frame 1 and used to coordinate the combined adjustment of the angle and position of the mold surface to be machined. Specifically, the rotating component... Component 4 includes a fixing plate 410 serving as the mounting base, which is fixedly connected to the fixing frame 1. A fixing block 403 is fixedly connected to the fixing plate 410 for securely clamping the mold. The rotating component 4 has two independent adjustment mechanisms inside, used for longitudinal and lateral angle adjustments respectively. The first adjustment mechanism includes a first motor 404 fixedly connected to the fixing plate 410, and a threaded rod 408 with one end connected to the output end of the first motor 404. A second support frame 407 is rotatably connected to the fixing plate 410, and a gear 409 is fixedly connected to the second support frame 407. The threaded rod 408 and the gear 409 constitute a worm gear transmission mechanism. When the first motor 404 drives the threaded rod 408 to rotate, the meshing transmission between the threaded rod 408 and the gear 409 can drive the second support frame 407 to rotate around the rotation connection point with the fixed plate 410. The guide plate 402 is fixedly connected to the top of the second support frame 407, so the guide plate 402 can achieve overall longitudinal angle adjustment as the second support frame 407 rotates. The second set of adjustment mechanisms includes a first support frame 405 fixedly connected to the bottom of the second support frame 407, and an output end connected to the first support frame 405. The fixedly connected second motor 406 directly drives the first support frame 405 to rotate when it starts. Since the first support frame 405 is fixedly connected to the second support frame 407, the rotation of the first support frame 405 will further drive the guide plate 402 to adjust its lateral angle. In addition, the cylinder 411 is mounted on the guide plate 402, and the limiting plate 401 is connected to the piston rod end of the cylinder 411. Through the extension and retraction of the cylinder 411, the limiting plate 401 can slide precisely along the surface of the guide plate 402, providing guidance for the movement of the mold and realizing fine-tuning of its position. The circulation component 5 includes a support block 503 and a water pump 502 fixed to the support block 503. The outlet of the water pump 502 is connected to a water pipe 501, the other end of which extends to the processing area of ​​the cylinder cutting tool 3 to deliver coolant to the cutting point. The vertical milling machine for mold surface processing is also equipped with a collection frame 505 for collecting waste liquid. The collection frame 505 is located below the rotating component 4 to receive and collect coolant flowing down from the processing area and carrying impurities. A filter screen 507 is provided inside the collection frame 505. The filter screen 507 is used for… The coolant undergoes preliminary impurity filtration. To prevent external debris from falling in and internal coolant from splashing out, a cover plate 506 is provided at the top opening of the collection frame 505, and a sealing strip 508 is provided between the contact edge of the cover plate 506 and the collection frame 505 to enhance the sealing effect. After the coolant is initially filtered by the filter screen 507, it flows out of the collection frame 505 and enters the filter cylinder 504 for further purification. The outlet of the filter cylinder 504 is connected to the inlet end of the water pump 502 through a pipeline, realizing the filtration and reuse of the coolant. To achieve coolant collection and filtration, the circulation assembly 5 further includes a collection frame 505 located below the rotating assembly 4, and a filter screen 507 is disposed inside the collection frame 505 for preliminary filtration of the coolant. As a further preferred embodiment, for finer purification, the circulation assembly 5 also includes a filter cylinder 504 located between the collection frame 505 and the inlet of the water pump 502, for further purification of the coolant filtered by the filter screen 507. As another preferred embodiment... In order to prevent contamination and liquid leakage, a cover plate 506 is provided at the top opening of the collection frame 505, and a sealing strip 508 is provided between the contact edge of the cover plate 506 and the collection frame 505. The sealing strip 508 can enhance the tightness of the connection between the cover plate 506 and the collection frame 505. As another preferred embodiment, in order to ensure the operational stability of the water pump 502, the circulation assembly 5 also includes a support block 503. The water pump 502 is fixedly installed on the support block 503, and the support block 503 provides a stable installation base for the water pump 502.

[0021] Working principle: Before processing the mold surface, the entire equipment is first securely installed on the work site using the fixed frame 1, and the mold to be processed is fixed on the fixed block 403 of the rotating component 4. When it is necessary to adjust the processing posture of the mold, the first motor 404 is started. The first motor 404 drives the threaded rod 408 to rotate. Since the threaded rod 408 and the gear 409 form a worm gear transmission mechanism, the rotation of the threaded rod 408 will drive the gear 409 to rotate, thereby causing the second support frame 407, which is fixedly connected to the gear 409, to rotate around the rotation connection point with the fixed plate 410. The top guide plate 402 changes its longitudinal tilt angle accordingly; simultaneously or separately, the second motor 406 is started, and the output end of the second motor 406 directly drives the first support frame 405 to rotate. Through the fixed connection between the first support frame 405 and the second support frame 407, the entire guide plate 402 is driven to adjust its lateral angle. Through the coordinated or independent work of the first motor 404 and the second motor 406, the composite adjustment of the longitudinal and lateral posture of the mold is realized. After the angle is determined, the limit plate 401 can be pushed along the surface of the guide plate 402 for precise linear position fine adjustment by extending and retracting the drive cylinder 411. During the processing, the cylinder cutting blade 3 slides along the slide rail 2 to cut the mold surface with the adjusted posture. At the same time, the circulation component 5 starts working, and the water pump 502 supported by the support block 503 starts, which transports the clean coolant in the filter cylinder 504 to the cutting area of ​​the cylinder cutting blade 3 through the water pipe 501 to cool down the blade and the mold. The used coolant, carrying the chips and impurities generated during processing, flows into the collection frame 505 below. The cover plate 506 and sealing strip 508 on the top of the collection frame 505 can prevent coolant from splashing out and debris from entering. The filter screen 507 inside the collection frame 505 performs the initial filtration of the coolant, filtering out larger particles of impurities. The coolant that has passed the initial filtration continues to flow into the filter cylinder 504 for secondary purification. The purified coolant is then drawn back by the water pump 502, thus realizing the recycling of the coolant.
