Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, and specifically to a grinding device for mold manufacturing. Background Technology

[0002] A mold is a tool used to make shaped objects. Different molds are composed of different parts. They mainly achieve the processing of the object's shape by changing the physical state of the material being molded. A mold grinding device is a device that performs grinding operations on the mold. Its main function is to grind the mold, making its rough surface smooth. With the development of technology, there are many types of grinding mechanisms on the market.

[0003] A search revealed that patent CN202222496220.0 discloses a grinding device for mold manufacturing. While this device, by pressing down the pressure rod, can disengage the ejector rod from the positioning groove and release the turntable's constraint, allowing direct rotation of the turntable to adjust the workpiece's grinding surface, it only allows adjustment of the critical grinding surface via turntable rotation and cannot adjust the grinding angle. This lack of grinding angle adjustment functionality can cause operational inconvenience. For example, grinding specific parts of a mold cannot be done directly with this device and requires other tools or methods, increasing complexity and time costs. Due to these limitations, the device is not highly adaptable to molds of different shapes and sizes, thus limiting its widespread application in mold manufacturing. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a grinding device for mold manufacturing, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A grinding device for mold manufacturing includes a base, on which a lifting screw and a guide module are mounted. A fixed seat is mounted on the base and limited by the lifting screw and the guide module. A grinding module is mounted on the fixed seat.

[0007] The guide module is provided with a fixing plate, a slider is installed on the back of the fixing plate, a slide rail is installed on the base, and the fixing plate is fixed on the base by the slider and the slide rail.

[0008] The fixed base is provided with a connecting plate, and a mounting plate is supported on the connecting plate by a support rod. A mounting seat is mounted on the mounting plate, and a grinding module is mounted on the mounting seat. A bracket is mounted on the connecting plate, and a long-shaft servo motor is mounted on the bracket. The long-shaft servo motor has transmission rods at both ends, and the transmission rods are inserted and fixed to the fixed plate.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the connecting plate adjusts the relative angle between the connecting plate and the fixed plate by rotating the transmission rod driven by a long-axis servo motor.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The long-axis servo motor boasts high-precision control, ensuring extremely accurate adjustment of the relative angle between the connecting plate and the fixed plate. This guarantees precise contact angle between the grinding surface and the mold surface, thereby improving grinding quality and efficiency. The servo motor employs closed-loop control, offering high stability and reliability. During angle adjustment, the long-axis servo motor maintains stable speed and torque output, avoiding angle adjustment errors caused by motor vibration or stalling. Driven by the long-axis servo motor, the relative angle between the connecting plate and the fixed plate can be flexibly adjusted. This design allows the grinding device to adapt to molds of different shapes and sizes, meeting diverse grinding needs.

[0013] Furthermore, the angle of the grinding module on the mounting plate is adjusted by a long-axis servo motor driving the connecting plate.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The long-axis servo motor boasts high-speed, high-precision motion control capabilities, ensuring accurate adjustment of the grinding module's angle. Through an internal encoder and controller, the servo motor converts its output into corresponding voltage and current signals, enabling fine adjustments to the grinding module's angle. Precise angle adjustment means a more accurate contact angle between the grinding surface and the mold surface, improving grinding uniformity and consistency. This helps reduce grinding defects caused by angle deviations, increasing mold yield and quality. Stable motion control means the grinding module can reach the required angle more quickly, shortening adjustment time. This helps improve production efficiency and reduces time wasted on angle adjustments. Driven by the long-axis servo motor, the connecting plate can flexibly adjust its relative angle to the fixed plate, enabling multi-angle adjustments of the grinding module. This design allows the grinding device to adapt to molds of different shapes and sizes, meeting diverse grinding needs.

[0016] Furthermore, the grinding module is equipped with a grinding machine and a pressure plate, and the grinding machine is clamped and fixed on the fixed base by the pressure plate and the mounting base.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] The grinder is securely fixed to the mounting base by the clamping action of the pressure plate and the mounting seat. This clamping method ensures that the grinder will not loosen or shift due to vibration or external forces during high-speed rotation and operation. The stable structure helps reduce errors and deviations during the grinding process, thereby improving grinding accuracy. The installation process of the grinder is relatively simple; it only needs to be placed on the mounting base and clamped in place by the pressure plate. This installation method saves installation time and costs, while also reducing the technical difficulty of the installation process. When the grinder needs to be replaced or repaired, it can be easily removed by simply loosening the pressure plate. This design makes the maintenance process more convenient, reducing maintenance costs and time.

[0019] Furthermore, a grinding head is installed at the output end of the grinding module.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] As the core component of the grinding module, the grinding head acts directly on the mold surface for fine grinding. Because grinding heads typically have high rotational speeds and cutting forces, they can quickly remove imperfections and uneven areas from the mold surface, thus improving grinding efficiency. The material and shape of the grinding head are customized according to the mold material and grinding requirements to ensure optimal grinding results. For example, polyurethane grinding heads feature high wear resistance, strong cutting force, and elastic polishing properties, reducing damage to the workpiece and increasing polishing speed during the polishing process. This customized grinding head ensures consistent and stable grinding quality.

[0022] Furthermore, the base is provided with a pad, and the pad is located directly below the grinding head.

[0023] The beneficial effects of adopting the above-mentioned further solutions are:

[0024] During operation, the grinding head experiences high-speed friction with the mold surface, generating significant cutting force and heat. If the grinding head acts directly on the base, the base surface is likely to be damaged due to prolonged wear. The shim design effectively isolates the grinding head from the base, protecting the base from wear and extending its lifespan. The shim design also allows for easy adjustment of the grinding head height to accommodate the grinding needs of different molds. By changing shims of different thicknesses or heights, the distance between the grinding head and the mold surface can be easily adjusted, ensuring that the grinding operation is performed within the appropriate range. This adjustability enhances the flexibility and adaptability of the grinding operation.

[0025] This invention provides a grinding device for mold manufacturing. It has the following beneficial effects:

[0026] This device achieves height adjustment of the fixed base through a lifting screw and guide module, allowing the grinding module to be flexibly adjusted according to different mold heights and shapes, ensuring the accuracy and stability of the grinding operation. The slider and slide rail design in the guide module provides stable guidance for the fixed base, ensuring smooth operation during lifting, lowering, and angle adjustment, and avoiding grinding errors caused by shaking.

[0027] The angle of the grinding module can be adjusted by rotating the connecting plate and transmission rod via a long-axis servo motor, thus meeting the grinding needs of different parts of the mold. This design increases the flexibility and adaptability of the device, making the grinding operation more efficient and precise. The design of the grinding module ensures that the grinding head can stably contact the mold surface, and through precise adjustment and control, high-precision grinding results can be achieved.

[0036] 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.

[0037] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0038] Example 1

[0039] A grinding device for mold manufacturing includes a base 1, on which a lifting screw 2 and a guide module 3 are mounted. A fixed seat 4 is mounted on the base 1 and limited by the lifting screw 2 and the guide module 3. A grinding module 5 is mounted on the fixed seat 4. The guide module 3 has a fixed plate 303, and a slider 302 is mounted on the back of the fixed plate 303. A slide rail 301 is mounted on the base 1. The fixed plate 303 is limited on the base 1 by the slider 302 and the slide rail 301. A pad 101 is provided on the base 1 and is located directly below the grinding head 503. When the grinding head 503 is working, it will rub against the mold surface at high speed, generating a large cutting force and heat. If the grinding head 503 acts directly on the base 1, the surface of the base 1 may be damaged due to prolonged wear. The design of the pad 101 can effectively isolate the grinding head 503 from the base 1, thereby protecting the base 1 from wear and extending its service life. The design of the shim 101 also allows for easy adjustment of the height of the grinding head 503 to accommodate the grinding needs of different molds. By replacing the shims 101 with different thicknesses or heights, the distance between the grinding head 503 and the mold surface can be easily adjusted, ensuring that the grinding operation is performed within the appropriate range. This adjustment function helps to improve the flexibility and adaptability of the grinding operation.

[0040] Example 2

[0041] To facilitate adjustment of the grinding angle of the grinding module 5, for example, as shown... Figures 1 to 4As shown, the present invention further includes: a fixed base 4 with a connecting plate 403, a mounting plate 401 supported by a support rod 405 on the connecting plate 403, a mounting seat 402 mounted on the mounting plate 401, and a grinding module 5 mounted on the mounting seat 402. The grinding module 5 includes a grinding machine 501 and a pressure plate 502. The grinding machine 501 is clamped and fixed to the fixed base 4 by the pressure plate 502 and the mounting seat 402. The grinding machine 501 is firmly fixed to the fixed base 4 by the clamping action of the pressure plate 502 and the mounting seat 402. This clamping method ensures that the grinding machine 501 will not loosen or shift due to vibration or external force during high-speed rotation and operation. The stable structure helps to reduce errors and deviations in the grinding process, thereby improving grinding accuracy. The installation process of the grinding machine 501 is relatively simple; it only needs to be placed on the mounting seat 402 and clamped and fixed by the pressure plate 502. This installation method saves installation time and cost, and also reduces the technical difficulty in the installation process. When the grinder 501 needs replacement or repair, it can be easily removed by simply loosening the pressure plate 502. This design makes maintenance more convenient, reducing maintenance costs and time. The output end of the grinding module 5 is equipped with a grinding head 503. As the core component of the grinding module 5, the grinding head 503 directly acts on the mold surface for fine grinding. Because the grinding head 503 typically has a high rotational speed and cutting force, it can quickly remove imperfections and uneven parts from the mold surface, thereby improving grinding efficiency. The material and shape of the grinding head 503 are customized according to the mold material and grinding requirements to ensure optimal grinding results. For example, polyurethane grinding heads 503 have strong wear resistance, high cutting force, and elastic polishing properties, which can reduce damage to the workpiece and increase polishing speed during the polishing process. This customized grinding head 503 ensures consistent and stable grinding quality. The angle of the grinding module 5 on the mounting plate 401 is adjusted by the long-axis servo motor 407 driving the connecting plate 403. The long-axis servo motor 407 has high-speed, high-precision motion control capabilities, ensuring precise adjustment of the angle of the grinding module 5. Through an internal encoder and controller, the servo motor converts the output into corresponding voltage and current signals, thereby achieving fine adjustments to the angle of the grinding module 5. Precise angle adjustment means that the contact angle between the grinding surface and the mold surface can be more accurate, thus improving the uniformity and consistency of grinding. This helps reduce grinding defects caused by angle deviations, improving the yield and quality of the mold. Stable motion control means that the grinding module 5 can reach the required angle more quickly, thus shortening the adjustment time. This helps improve production efficiency and reduce the time wasted on angle adjustments. Driven by the long-axis servo motor 407, the connecting plate 403 can flexibly adjust the relative angle with the fixed plate 303, thereby achieving multi-angle adjustment of the grinding module 5.This design allows the grinding device to adapt to molds of different shapes and sizes, meeting diverse grinding needs. A bracket 406 is mounted on the connecting plate 403, and a long-axis servo motor 407 is mounted on the bracket 406. The long-axis servo motor 407 has transmission rods 404 at both ends, which are inserted and fixed to the fixed plate 303. The connecting plate 403 adjusts the relative angle between itself and the fixed plate 303 by rotating the transmission rods 404 driven by the long-axis servo motor 407. The long-axis servo motor 407 has high-precision control capabilities, ensuring very accurate adjustment of the relative angle between the connecting plate 403 and the fixed plate 303. This ensures accurate contact angle between the grinding surface and the mold surface, thereby improving grinding quality and efficiency. The servo motor uses closed-loop control, exhibiting high stability and reliability. When adjusting the angle, the long-axis servo motor 407 maintains stable speed and torque output, avoiding angle adjustment errors caused by motor vibration or stalling. Driven by the long-axis servo motor 407, the connecting plate 403 can flexibly adjust its relative angle with the fixed plate 303. This design allows the grinding device to adapt to molds of different shapes and sizes, meeting diverse grinding needs.

[0042] Working principle:

[0043] When the height of the grinding module 5 needs to be adjusted, the lifting screw 2 is rotated, causing the fixed seat 4 to move up and down along the lifting screw 2, thereby achieving the purpose of height adjustment. The lifting screw 2 is driven to rotate by a motor or other drive device. Due to the threaded engagement between the screw and the nut, the rotational motion is converted into the linear motion of the nut. This motion allows the fixed seat 4 to move up and down along the lifting screw 2, thereby adjusting the height of the grinding module 5. The guide module 3 consists of a slide rail 301 and a slider 302, which fit tightly together to ensure the stability of the fixed seat 4 during the lifting process. The slider 302 slides up and down along the slide rail 301, providing stable guidance and support for the fixed seat 4.

[0044] When the angle of the grinding module 5 needs to be adjusted, the long-axis servo motor 407 is activated, driving the connecting plate 403 (and the grinding module 5) to rotate relative to the fixed plate 303 via the transmission rod 404 until the desired angle is reached. The long-axis servo motor 407 is connected to the fixed plate 303 via the transmission rod 404, and its rotation drives the connecting plate 403 (and the grinding module 5 mounted on the connecting plate 403) to rotate relative to the fixed plate 303. This rotation method achieves the adjustment of the angle of the grinding module 5. The transmission rod 404, acting as a bridge connecting the long-axis servo motor 407 and the fixed plate 303, transmits torque and force. It ensures that the rotation of the long-axis servo motor 407 is accurately converted into the rotation of the connecting plate 403 (and the grinding module 5). The connecting plate 403 supports and fixes the grinding module 5 and is connected to the long-axis servo motor 407 via the bracket 406. The bracket 406 provides stable support and a suitable mounting position for the long-axis servo motor 407.

[0045] After adjusting the height and angle, start the grinder 501, causing its output end (grinding head 503) to rotate at high speed to grind the mold surface. By controlling parameters such as the rotation speed, pressure, and grinding time of the grinder 501, the desired grinding effect can be obtained. The grinder 501 is the core component of the grinding module 5, and it is fixed to the mounting base 4 by the pressure plate 502 and the mounting base 402. When the grinder 501 is working, its output end (grinding head 503) rotates at high speed to grind the mold surface. The pressure plate 502 is used to fix the grinder 501 to the mounting base 402 to ensure the stability and reliability of the grinder 501 during the grinding process.
