[0002] Precision milling of the mold blank is a key process in mold manufacturing. It refers to machining the mold blank to the required dimensions, shape and surface quality through high-precision milling, laying the foundation for subsequent cavity machining or polishing.

[0003] When performing precision milling on a mold blank, a precision milling machine is used. However, when a general precision milling machine processes a mold blank, the milling cutter produces steel chips when cutting the blank. These steel chips will fly in the direction of rotation of the milling cutter and may fly onto the moving guide rail of the precision milling machine, causing the guide rail to get stuck and affecting the normal operation of the precision milling machine. Utility Model Content

[0004] To address the shortcomings of existing technologies, when a milling cutter removes a blank, it generates steel chips. These chips can fly off in the direction of the milling cutter's rotation and may land on the moving guide rail of the milling machine, causing the guide rail to jam and affecting the normal operation of the milling machine. This invention proposes a milling device for blanks.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a precision milling device for mold blanks, including a single-head precision milling machine body, the single-head precision milling machine body including a machine body, a threaded guide rail fixedly connected to the top of the machine body, a movable table movably connected to the surface of the threaded guide rail, a gantry clamping table fixedly connected to the top of the movable table, a mold blank body movably connected to the top of the movable table, a cutting machine fixedly connected to the surface of the machine body, and a collecting mechanism provided on the surface of the movable table;

[0022] 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 scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a precision milling device for mold blanks. (Refer to...) Figure 1 and Figure 5 A precision milling device for mold blanks includes a single-head precision milling machine body 1. The single-head precision milling machine body 1 includes a machine body 101. A threaded guide rail 102 is fixedly connected to the top of the machine body 101. A movable table 103 is movably connected to the surface of the threaded guide rail 102. A gantry clamping table 105 is fixedly connected to the top of the movable table 103. A mold blank body 2 is movably connected to the top of the movable table 103. A cutting machine 104 is fixedly connected to the surface of the machine body 101. A collecting mechanism 3 is provided on the surface of the movable table 103.

[0025] The collection mechanism 3 includes a collection box 301, the bottom of which is fixedly connected to the top of the moving platform 103. A screening box 312 is movably connected to the inner cavity of the moving platform 103, and a coarse screen 313 is fixedly connected to the inner side of the screening box 312.

[0026] Reference Figure 5A fine screen 314 is fixedly connected to the inner side of the screening box 312. The fine screen 314 is located at the bottom of the coarse screen 313. By setting the fine screen 314, after the coarse screen 313 filters out the larger steel chips, the fine screen 314 can block the small steel chips. This allows the water that falls back into the inner cavity of the collection box 301 to be filtered, so that the water pumped by the second water pump 309 in the collection box 301 is relatively clean. This avoids the situation where the water pumped by the second water pump 309 contains steel chips and is eventually sprayed out by the bellows 304, which would affect the cutting accuracy of the milling cutter in the cutting machine 104 in cutting the mold body 2.

[0027] Reference Figure 4 and Figure 5 The top of the screening box 312 is fixedly connected with a snap-fit ​​block 310. There are two snap-fit ​​blocks 310. The surface of the snap-fit ​​block 310 is movably connected to the surface of the collection box 301. The snap-fit ​​block 310 sets a limit effect on the placement of the screening box 312 in the inner cavity of the collection box 301, and also makes it convenient for the staff to take the screening box 312 out of the inner cavity of the collection box 301 through the snap-fit ​​block 310.

[0028] Reference Figure 1 and Figure 3 A guide plate 305 is fixedly connected to the surface of the cutting machine 104. The guide plate 305 is arc-shaped. The guide plate 305 blocks and protects the steel chips cut from the die blank body 2 by the rotation direction of the milling cutter in the cutting machine 104, preventing the steel chips from flying everywhere. Finally, the steel chips can be guided by the guide plate 305 to the inner cavity of the sieve box 312 in the collection box 301 and collected.

[0029] Reference Figure 4 A second water pump 309 is fixedly connected to the surface of the collection box 301. The input end of the second water pump 309 is fixedly connected to the inner cavity of the collection box 301. A connecting pipe 303 is fixedly connected to the output end of the second water pump 309. One end of the connecting pipe 303 is fixedly connected to a water storage box 302. The surface of the water storage box 302 is fixedly connected to the surface of the gantry clamping platform 105. A first water pump 308 is fixedly connected to the top of the water storage box 302. An output pipe 306 is fixedly connected to the output end of the first water pump 308. A corrugated pipe 304 is fixedly connected to the surface of pipe 306. It is used in conjunction with water storage box 302, connecting pipe 303, output pipe 306, first water pump 308 and second water pump 309. Water can be drawn from the inner cavity of collection box 301 by second water pump 309, and then guided to the inner cavity of water storage box 302 through connecting pipe 303. Finally, it is drawn by first water pump 308, and then guided to the inner cavity of corrugated pipe 304 through output pipe 306 and sprayed on the position where the milling cutter and the mold body 2 in the cutting machine 104 are in contact.

[0030] Reference Figure 4 Two fixing blocks 307 are fixedly connected to the surface of the output tube 306. The surface of the fixing block 307 is fixedly connected to the surface of the gantry clamping table 105. The fixing blocks 307 provide a fixed support for the output tube 306, preventing the output tube 306 from shaking for a long time during operation and improving the stability of the output tube 306 during operation.

[0031] Reference Figure 4 The input end of the first water pump 308 passes through the water storage box 302 and is fixedly connected to the extraction pipe 311. One end of the extraction pipe 311 is located at the bottom of the inner cavity of the water storage box 302. The extraction pipe 311 is designed to prevent the first water pump 308 from failing to extract water from the bottom of the inner cavity of the water storage box 302 when the water level inside the water storage box 302 is too low. Since one end of the extraction pipe 311 is located at the bottom of the inner cavity of the water storage box 302, it can help the first water pump 308 extract water from the bottom of the inner cavity of the water storage box 302.

[0032] Working principle: When precision milling of the mold blank is required, the mold blank body 2 is placed on the surface of the moving table 103, and then the output end of the cylinder in the gantry clamping table 105 contacts the surface of the mold blank body 2 to clamp it. Then, by starting the cutting machine 104, the precision milling cutter in the cutting machine 104 rotates and contacts the surface of the mold blank body 2. Then, through the operation of the threaded guide rail 102, the threaded rod of the threaded guide rail 102 drives the moving table 103 to slide on the surface of the threaded guide rail 102, thereby causing the mold blank body 2 to slide on the surface of the precision milling cutter of the cutting machine 104, and precision milling is performed on the mold blank body 2. The above is the existing technology and will not be elaborated further. When the precision milling cutter cuts the surface of the mold blank body 2, the cut steel chips will... As the milling cutter rotates, the spatter may splash onto the surface of the thread guide 102, potentially affecting the sliding of the moving table 103 on the thread guide 102 surface. Therefore, a guide plate 305 is fixedly connected to the surface of the cutting machine 104. Guided by the guide plate 305, the splashed steel chips are guided into the collection box 301 and collected in the inner cavity of the screening box 312. When the milling cutter cuts the mold blank body 2, high temperatures are generated. To avoid the high temperature affecting the accuracy of cutting the mold blank body 2, water can be added to the inside of the collection box 301 before milling the mold blank body 2. The water inside the collection box 301 is then extracted by the operation of the second water pump 309 and guided to the water storage box 3 through the connecting pipe 303. 02. Water is stored internally. When the milling cutter finishes the surface of the mold blank body 2, the first water pump 308 starts working. The input end of the first water pump 308 draws water from the water storage box 302 through the extraction pipe 311 and outputs it to the inner cavity of the output pipe 306 through its output end. Finally, the water is sprayed onto the cutting position of the mold blank body 2 by the milling cutter through the bellows 304 to cool it down. The bellows 304 is made of stainless steel corrugated material, and due to its characteristics, it can be twisted at a suitable angle and fixed, making it convenient to adjust the water spray position. A portion of the used water flows back into the collection box 301 and the inner cavity of the sieve box 312, where impurities in the water are filtered through the coarse screen 313 and the fine screen 314. The clean water will fall into the bottom of the collection box 301 and continue to be drawn by the second water pump 309 for recycling. When the inner cavity of the screening box 312 is filled with steel filings, the operator can lift the locking block 310 after the single-head milling machine body 1 stops working. The locking block 310 will drive the screening box 312 out of the inner cavity of the collection box 301 and pour out the steel filings. Then, the screening box 312 will be put back into the inner cavity of the collection box 301 until the surface of the locking block 310 contacts the surface of the collection box 301 to prevent the screening box 312 from falling to the bottom of the collection box 301. The locking block 310 also makes it easy for the operator to take the screening box 312 out of the inner cavity of the collection box 301.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
