[0001] The present invention relates to the technical field of mold processing, and in particular to a grinding machine for mold raw materials. Background Art

[0002] A grinding machine for mold raw materials is a device used for finely grinding mold materials, mainly for grinding mold raw materials such as metals, ceramics, plastics, etc. into the required fineness or surface quality. Such a device usually consists of a grinding disc, grinding medium, drive system, etc. Through the actions of rotation, pressure, friction, etc., the mold raw materials interact with the grinding medium, thereby achieving the grinding of the materials.

[0003] During the grinding process, the grinding machine for mold raw materials usually generates waste chips. These waste chips are mainly generated by the friction, cutting, and particle shedding of the materials during the grinding process. The accumulation of waste chips on the grinding surface may lead to uneven contact between the grinding medium and the raw materials, thereby affecting the grinding effect and producing an uneven surface. It may also contaminate the grinding medium, reduce its grinding efficiency, and may cause scratches or irregular grinding marks on the surface, thereby affecting the final accuracy and finish.

[0004] In response to the waste chips generated by grinding, some existing grinding machines are equipped with special cleaning devices, including using a vacuum cleaner to suck up the waste chips, or cleaning the surface of the machine tool with a scraper, etc. However, it is difficult for the vacuum cleaner to accurately cover the surface of the raw materials and cannot ensure the timely removal of the waste chips generated on the surface of the raw materials at any time, resulting in poor cleaning effect. Moreover, the scraper cannot clean the surface of the machine tool during the grinding process, reducing the processing efficiency. Summary of the Invention

Detailed implementation manners

[0018] The present invention will be further described in detail below in conjunction with the drawings and the implementation manners: As Figure 1 , 2 , 3 and 7 show a mold raw material grinding machine, including a machine tool housing 1, a bracket 3 is connected to the machine tool housing 1, a grinding mechanism 4 is connected to the inner end of the bracket 3, an air pump 5 is connected to the outer end of the grinding mechanism 4, a processing table 2 is connected to the upper part of the inner wall of the machine tool housing 1, the bracket 3 is arranged directly above the processing table 2, the output end of the grinding mechanism 4 is directed downward, a plurality of chip removal holes 6 which are densely arranged and communicated with the inner cavity of the machine tool housing 1 are formed in the processing table 2, and a fan 10 is connected to the bottom of the inner wall of the machine tool housing 1.

[0019] The mold raw material grinding machine is a device used for finely grinding mold materials. It is mainly used to grind mold raw materials such as metals, ceramics, plastics, etc. into the required fineness or surface quality. During the grinding process of the mold raw material grinding machine, waste chips are usually generated. The accumulation of waste chips on the grinding surface may lead to uneven contact between the grinding medium and the raw material, thus affecting the grinding effect, resulting in an uneven surface, and may also contaminate the grinding medium, reducing its grinding efficiency, and may cause scratches or irregular grinding marks on the surface, thereby affecting the final precision and finish. Currently, some grinding machines are equipped with special cleaning devices, including using a vacuum cleaner to suck up waste chips, or cleaning the machine surface with a scraper, etc. However, the vacuum cleaner is difficult to precisely cover the raw material surface and cannot ensure the timely removal of waste chips generated on the raw material surface at any time, resulting in poor cleaning effect. And the scraper cannot clean the machine surface during the grinding process at the same time, reducing the processing efficiency.

[0020] The grinding mechanism in this solution includes a first grinding feeding pipe 41, a second grinding feeding pipe 42, a grinding clamping ring 43, a grinding chuck 44, and a connecting column 45 for connecting an air pump 5. The first grinding feeding pipe 41 and the second grinding feeding pipe 42 are usually responsible for feeding raw materials in stages. The first grinding feeding pipe 41 is used for feeding large-particle raw materials in the rough grinding stage, while the second grinding feeding pipe 42 is used for supplementing fine particles or auxiliary materials in the fine grinding stage to ensure the precise control of the grinding process; the grinding clamping ring 43 is mainly used to fix the grinding disc or seal the connection part to prevent loosening or dust leakage, and is usually made of wear-resistant materials; the grinding chuck 44 is similar to a clamping mechanism, used to fix the raw material or grinding tool to be ground, and realizes uniform grinding through rotary drive. Some designs may also support adjusting the clamping force or angle to adapt to workpieces of different shapes. These components work together to complete the entire process from raw material feeding, fixing and clamping to fine grinding, ensuring the efficient and precise processing of mold raw materials.

[0021] In this solution, the processing table 2 is used to place the mold raw materials to be processed, the grinding mechanism 4 is used to grind the raw materials, and the support 3 is provided with a moving mechanism for driving the grinding mechanism 4 to move, which can be an electric track or an electric push rod, so that the grinding mechanism 4 can grind the raw materials at a specified position. The working principles of the above-mentioned grinding mechanism 4 and the moving mechanism are both known prior arts, which are well-known and widely used by those skilled in the art, so no detailed description will be given here. During the process of grinding the raw materials by the grinding mechanism 4, the user starts the air pump 5 to send an air flow with appropriate intensity to the surface of the raw materials, so as to blow off the waste chips generated at the grinding place from the surface of the raw materials and make them fall onto the processing table 2. At the same time, the user starts the fan 10 inside the machine tool housing 1. The fan 10 can be set as a centrifugal fan, which can provide a relatively high wind pressure and flow rate. Through the fan 10, the air inside the machine tool housing 1 can be effectively extracted, so that a negative pressure is formed in the inner cavity of the machine tool housing 1. As a result, the air above the processing table 2 will continuously pour into the inner cavity of the machine tool housing 1 through a plurality of chip discharge holes 6, and then suck the waste chips falling on the surface of the processing table 2 into the inner cavity of the machine tool housing 1 in time, avoiding the accumulation of waste chips on the processing table 2 or their dispersion into the air. Such a setting can clean the waste chips on the surface of the raw materials and the surface of the processing table 2 in a timely and effective manner without affecting the grinding work.

[0022] As Figures 6-7 shown, a tray 7 whose inner wall bottom is slidably connected to the bottom of the inner wall of the machine tool housing 1 and whose shape matches the inner cavity thereof, the outer end of the tray 7 abuts against the inner wall of the machine tool housing 1, the bottom end of the tray 7 covers the output end of the fan 10, and one end of the tray 7 extends to the outside of the machine tool housing 1 and is connected with a handle. A through hole whose shape matches the output end of the fan 10 is opened at the center position of the bottom end of the inner wall of the tray 7, the through hole and the output end of the fan 10 are arranged at the same vertical position, and a net plate 8 is covered and connected to the inner wall of the through hole.

[0023] In this solution, the waste chips sucked into the inner cavity of the machine tool housing 1 can fall into the tray 7 for collection. The user can pull the handle to take out the tray 7 from the machine tool housing 1, which is convenient for centralized treatment of the collected waste chips. When the tray 7 is located in the inner cavity of the machine tool housing 1, the net plate 8 covers the output end of the fan 10, playing an isolating role between the waste chips and the fan 10. The net plate 8 can be made of a metal mesh, which can effectively prevent the waste chips from being sucked into the fan 10 and damaging the internal structure of the fan 10, and at the same time will not affect the air flow.

[0024] As Figures 4-5 shown, the inner cavity of the chip discharge hole 6 is set in a funnel shape with a large upper part and a small lower part.

[0025] In this solution, the inner cavity of the chip discharge hole 6 is set in the shape of a funnel with a larger upper part and a smaller lower part, which can increase the size of the upper opening of the chip discharge hole 6, making it easier for waste chips to enter the inner cavity of the chip discharge hole 6. At the same time, the lower part of the chip discharge hole 6 maintains a narrow channel to prevent air from entering with too large a flow rate, avoiding the situation where the inner cavity of the machine tool housing 1 fails to form a negative pressure in time. Moreover, the chip discharge hole 6 being set in the shape of a larger upper part and a smaller lower part can accelerate the air flowing through the chip discharge hole 6, enhancing the suction force formed by the air on the surface of the processing table 2 and promoting the rapid entry of waste chips into the inner cavity of the machine tool housing 1.

[0026] As Figure 6 shown, a pair of symmetrically arranged intercepting plates 9 are connected to the inner wall of the machine tool housing 1. The intercepting plates 9 are arranged between the processing table 2 and the tray 7. There is a gap between the pair of intercepting plates 9, and the remaining sides of the pair of intercepting plates 9 except for the mutually approaching ends are in contact with the inner wall of the machine tool housing 1. The intercepting plates 9 are inclined downward towards the center position of the inner cavity of the machine tool housing 1, and the surface of the intercepting plates 9 is coated with an electrostatic coating. A power source is connected to the inner cavity of the machine tool housing 1, and both of the pair of intercepting plates 9 are connected to the power source.

[0027] During the grinding process of this solution, the user activates the power source to energize the pair of intercepting plates 9. The coating of the electrostatic material will cause an electric field to form on the surface of the intercepting plates 9, and the waste chip particles will become charged due to their interaction with the electric field, causing these particles to be attracted to the surface of the intercepting plates 9, forming a dust collection effect. This setting can prevent waste chips from flying in the machine tool housing 1 and temporarily concentrate most of the waste chips on the intercepting plates 9, avoiding excessive waste chips accumulating on the mesh plate 8 and causing blockage. When the grinding work is completed, the user turns off the power source and the blower 10, and the waste chips on the intercepting plates 9 will slide down along the inclined surface of the intercepting plates 9 into the tray 7.

[0028] The specific implementation process is as follows: In use, the user places the raw materials to be ground on the surface of the processing table 2, and grinds the raw materials through the grinding mechanism 4. During the grinding process, the user simultaneously starts the air pump 5, the power supply connected to the intercepting plate 9 inside the machine tool housing 1, and the fan 10. The air pump 5 conveys an air flow of appropriate intensity to the surface of the raw materials, blows the waste chips generated at the grinding area off the surface of the raw materials, and makes them fall onto the processing table 2. The fan 10 can extract the air inside the machine tool housing 1, creating a negative pressure in the inner cavity of the machine tool housing 1. As a result, the air above the processing table 2 will continuously pour into the inner cavity of the machine tool housing 1 through a plurality of chip discharge holes 6, sucking the waste chips that have fallen onto the surface of the processing table 2 into the inner cavity of the machine tool housing 1 in a timely manner. An electric field will be formed on the surface of the energized intercepting plate 9, concentrating the sucked waste chips on the surface of the intercepting plate 9. Some waste chips will continue to fall into the tray 7. The mesh plate 8 can isolate the waste chips to prevent them from being sucked into the fan 10. When the grinding work is completed, the user turns off the power supply and the fan 10. The waste chips on the intercepting plate 9 will slide down along the inclined surface of the intercepting plate 9 into the tray 7. The user can pull the handle to take out the tray 7 from the machine tool housing 1, and then centrally process the collected waste chips.

[0029] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
