Description

Technical Field

[0001] The present invention relates to the technical field of die-casting molds, and particularly to a die-casting mold for the production of electronic throttle valves. Background Art

[0002] Die-casting mold is a method of casting liquid die forging, a process completed on a dedicated die-casting forging machine. Its basic process is: the molten metal is first cast into the mold cavity at low speed or high speed. The mold has a movable cavity surface, which is pressurized and forged during the cooling process of the molten metal, eliminating the shrinkage cavity and porosity defects of the blank, and also making the internal structure of the blank reach the broken grains in the forged state. The electronic throttle valve is an important control component of an automobile engine, consisting of an engine, a speed sensor, a throttle valve, etc. The electronic throttle valve can accurately control the throttle opening, not only improving fuel economy, reducing emissions, but also obtaining satisfactory handling performance. On the other hand, it can integrate idle control, cruise control, and vehicle stability control, etc., simplifying the control system structure. Die-casting molding is also required in the production of the electronic throttle valve housing.

[0003] Due to long-term production, during the production process of die-casting molds, pollutants such as carbon deposition on the surface of the die-casting mold, residual release agent, lubricant dirt, and alloy chip shedding residues and dust accumulate on the mold, seriously affecting die-casting production. Therefore, we propose a die-casting mold for the production of electronic throttle valves. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a die-casting mold for the production of electronic throttle valves, including:

[0005] A mold plate, which is used to adapt the molten metal poured into the pouring groove to make its shape consistent with the required production shape, facilitating the production of different specifications of fittings using mold plates with different internal dimensions;

[0006] An elliptical block, which can support or release the support of the bottom of the mold plate by manual rotation, facilitating the disassembly, unloading, and size replacement of the mold plate at any time, and a mold table provided on the top of the elliptical block;

[0007] A bottom support column, which supports the bottom of the mold table and separates the bottom surface of the mold table from the ground by a certain distance, facilitating the staff to disassemble and replace the mold plate from below the mold table;

[0008] A cleaning device, which cleans the inner wall of the groove by scraping multiple times to prevent dirt such as debris and residues from remaining on the inner wall of the mold groove and affecting subsequent die-casting production;

[0009] The bottom of the mold table is rotatably connected to the top of the elliptical clamping block by a rotating bolt. Four elliptical clamping blocks are provided and evenly distributed at the bottom of the mold table. The bottom of the mold table is fixedly connected to the top of the bottom support column. Four bottom support columns are provided and evenly distributed at the bottom of the mold table;

[0010] Among them, the cleaning device includes:

[0011] A model scraping plate, the shape of which is set to be consistent with the outer contour of the mold. The overflowing metal material is separated in a break-off manner by the model scraping plate, preventing not only inconsistent forming shapes but also difficult discharging when the molten metal is accidentally poured out of the mold hole;

[0012] A mold hole is opened at the top of the mold table. Concave connecting plates are fixedly connected to both sides of the mold table. A motor is fixedly connected to the bottom inner wall of the concave connecting plate. The driving shaft of the motor is fixedly connected to an electric telescopic rod. The bottom of the electric telescopic rod is fixedly connected to a cleaning device. The inner wall of the mold hole is slidably connected to the outer surface of the mold plate;

[0013] An arc-shaped inclined groove is opened on the outer surface of the model scraping plate. The inclined angle arc edge of the arc-shaped inclined groove is set to facilitate material pre-storage and sliding, preventing excessive friction loss caused by too large a contact area during scraping by the model scraping plate and making it difficult to use for a long time. An abrasive mechanism is fixedly connected to the inner wall of the arc-shaped inclined groove. A scraping mechanism is fixedly connected to the inner wall of the arc-shaped inclined groove. The top of the model scraping plate is rotatably connected to an upper round block by a rotating bolt. Wave-shaped flexible plates are fixedly connected to the four sides of the upper round block. The metal material slag slides outward under the centrifugal force with the high-speed rotation of the wave-shaped flexible plates and falls off the top surface of the mold table, preventing a large amount of slag from remaining at the position near the mold hole on the mold table and affecting the subsequent die-casting effect. The wave-shaped flexible plate retracts to a wave shape and its length is less than the radius of the model scraping plate, preventing damage to the wave-shaped flexible plate caused by contact and extrusion between the mold table and the wave-shaped flexible plate when the model scraping plate moves downward;

[0014] Four abrasive mechanisms are provided and evenly distributed on the inner wall of the arc-shaped inclined groove. Four scraping mechanisms are provided and evenly distributed on the inner wall of the arc-shaped inclined groove. The top of the upper round block is fixedly connected to the bottom of the electric telescopic rod.

[0015] Furthermore, the abrasive mechanism comprises an arc-shaped penetration rod, the outer surface of which is sleeved with a threaded grinding block and slidably connected thereto, the threaded grinding block frictionally grinds and cleans the inner wall of the mold hole, preventing dust or slag particles that are not scraped off by the model scraper from remaining on the inner wall of the mold hole, thereby increasing the friction and damage of the contact between the parts and the mold hole, and the rotating threaded grinding block rotates out the slag accumulated in the annular arc bevel groove, thereby preventing excessive slag and other debris from accumulating deep in the inner wall of the annular arc bevel groove and being difficult to handle, circular through holes are provided at both ends of the threaded grinding block, and the threaded grinding block is convenient for rotation by providing a circular through hole with a radius larger than that of the arc-shaped penetration rod, To prevent the threaded round block from getting stuck when it is sleeved on the arc-shaped penetration rod and restricted by the arc of the arc-shaped penetration rod during rotation, the inner wall of the circular through hole is fixedly connected with a corrugated ring piece, and the corrugated ring piece completely blocks the inner wall of the circular through hole from both ends to prevent the slag in the annular arc bevel groove from filling the circular through hole, causing the threaded grinding block to be difficult to rotate due to excessive friction. Both ends of the arc-shaped penetration rod are fixedly connected to the inner wall of the annular arc bevel groove, four arc-shaped penetration rods are provided and evenly distributed on the inner wall of the annular arc bevel groove, multiple threaded grinding blocks are provided and evenly distributed on the arc-shaped penetration rod, and multiple corrugated ring pieces are provided and evenly distributed on the inner wall of the circular through hole.

[0016] Furthermore, the scraping mechanism includes an arc-shaped wave plate, which performs a second scraping cleaning on the inner wall of the mold hole to prevent the inner wall of the mold hole from still having residual slag particles caused by grinding of the threaded grinding block; the outer surface of the arc-shaped wave plate is fixedly connected with an arc-shaped brush, which performs friction cleaning on the surface of the rotating threaded grinding block to prevent the slag or dust particles attached to the surface of the threaded grinding block from increasing friction and being damaged and difficult to use for a long time; when the threaded grinding block rotates, it cooperates with the arc-shaped brush to move and comb the arc-shaped brush to prevent the arc-shaped brush from being used for a long time and causing the brushes to break apart. Too much material residue will affect the subsequent cleaning efficiency. An arc-shaped side hole is opened at the bottom of the arc-shaped wave plate. The fallen material residue and other debris are continuously discharged downward from the arc-shaped side hole along with the stirring, so as to prevent a large amount of material residue and dust removed by stirring from still accumulating between the arc-shaped wave plate and the inner wall of the annular arc bevel groove. The bottom of the arc-shaped wave plate is fixedly connected to the inner wall of the annular arc bevel groove. The arc-shaped wave plate is provided with multiple and evenly distributed on the inner wall of the annular arc bevel groove. The arc-shaped brush is provided with multiple and evenly distributed on the outer surface of the arc-shaped wave plate. The arc-shaped side hole is provided with multiple and evenly distributed on the bottom of the arc-shaped wave plate.

[0017] The present invention has the beneficial effects:

[0018] 1. The present invention allows the metal slag to slide outward under the centrifugal force as the corrugated soft plate rotates at high speed to separate from the top surface of the mold table, thereby preventing a large amount of slag from remaining on the mold table near the mold hole and affecting the subsequent die-casting effect. The threaded grinding block performs friction-type grinding and cleaning on the inner wall of the mold hole to prevent the dust or slag particles that are not scraped off by the model scraper from remaining on the inner wall of the mold hole and the increased friction of the contact between the parts. The arc-shaped wave plate performs scraping-type cleaning on the inner wall of the mold hole again to prevent the slag particles that are finely ground by the threaded grinding block from still remaining on the inner wall of the mold hole.

[0019] 2. The present invention provides a cleaning device, and the overflowed metal material is separated by a crushing method through the model scraper to prevent the poured metal liquid from accidentally overflowing the mold hole, which not only causes inconsistent forming shapes but also makes it difficult to unload the material. The beveled arc edge of the annular arc chute is arranged to facilitate the pre-storage and sliding of materials, and prevent the model scraper from having too large a contact area when scraping, resulting in excessive friction loss and difficulty in long-term use. The metal slag slides outward under the centrifugal force as the high-speed rotation of the corrugated soft plate separates from the top surface of the mold table, preventing a large amount of slag from remaining on the mold table near the mold hole and affecting the subsequent die-casting effect. The corrugated soft plate retracts to a waveform with a length less than the radius of the model scraper, preventing the mold table from contacting and squeezing the corrugated soft plate when the model scraper moves downward, causing damage to the corrugated soft plate.

[0020] 3. The present invention provides an abrasive mechanism. The threaded grinding block is convenient for rotation by providing a circular through hole with a radius larger than that of the arc-shaped penetration rod, so as to prevent the threaded round block from being stuck when being sleeved on the arc-shaped penetration rod and being restricted by the arc of the arc-shaped penetration rod during rotation. The threaded grinding block performs friction grinding and cleaning on the inner wall of the mold hole, so as to prevent dust or slag particles that are not scraped off by the model scraper from remaining on the inner wall of the mold hole, thereby increasing the friction and damage of the contact between the parts and the threaded grinding block. The rotating threaded grinding block rotates out the slag accumulated in the annular arc bevel groove, so as to prevent excessive slag and other debris from accumulating deep in the inner wall of the annular arc bevel groove and being difficult to handle. The corrugated ring piece completely blocks the inner wall of the circular through hole from both ends, so as to prevent the slag in the annular arc bevel groove from filling up the circular through hole, thereby causing the threaded grinding block to be difficult to rotate due to excessive friction.

[0021] 4. The present invention provides a scraping mechanism, and the arc-shaped wave plate scrapes and cleans the inner wall of the mold hole again to prevent the inner wall of the mold hole from still having fine slag particles caused by the threaded grinding block remaining on the inner wall of the mold hole; the arc-shaped brush frictionally cleans the surface of the rotating threaded grinding block to prevent the slag or dust particles attached to the surface of the threaded grinding block from increasing friction and damage, making it difficult to use for a long time; when the threaded grinding block rotates, it cooperates with the arc-shaped brush to move and comb the arc-shaped brush to prevent the arc-shaped brush from being used for a long time, resulting in excessive slag being mixed between the brushes and affecting subsequent cleaning efficiency; the slag and other debris that slide down are continuously discharged downward from the arc-shaped side hole along with the moving, to prevent a large amount of slag and dust removed by the moving from still accumulating between the arc-shaped wave plate and the inner wall of the annular arc bevel groove.

Specific embodiments

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific purposes.

[0033] The first embodiment, please refer to Figures 1-4 , the present invention is a die-casting mold for the production of an electronic throttle, including:

[0034] The mold plate 1 is used to adapt the molten metal poured into the groove so that its shape is consistent with the required production shape;

[0035] The elliptical chuck 2 can support or release the support of the bottom of the mold plate 1 by manual rotation, and the mold table 3 arranged on the top of the elliptical chuck 2;

[0036] The bottom support column 4 supports the bottom of the mold table 3 and separates the bottom surface of the mold table 3 from the ground by a certain distance;

[0037] The cleaning device 9 cleans the inner wall of the groove multiple times by scraping cleaning;

[0038] The bottom of the mold table 3 is rotatably connected to the top of the elliptical chuck 2 through a rotating bolt. Four elliptical chucks 2 are provided and evenly distributed at the bottom of the mold table 3. The bottom of the mold table 3 is fixedly connected to the top of the bottom support column 4. Four bottom support columns 4 are provided and evenly distributed at the bottom of the mold table 3;

[0039] Among them, the cleaning device 9 includes:

[0040] The model scraping plate 901 is set to have a shape consistent with the outer contour of the mold;

[0041] A mold hole 5 is opened at the top of the mold table 3. Concave connecting plates 6 are fixedly connected to both sides of the mold table 3. A motor 7 is fixedly connected to the bottom of the inner wall of the concave connecting plate 6. The driving shaft of the motor 7 is fixedly connected to an electric telescopic rod 8. The bottom of the electric telescopic rod 8 is fixedly connected to the cleaning device 9. The inner wall of the mold hole 5 is slidably connected to the outer surface of the mold plate 1;

[0042] An arc-shaped inclined groove 902 is opened on the outer surface of the model scraping plate 901. An abrasive mechanism 903 is fixedly connected to the inner wall of the arc-shaped inclined groove 902. A scraping mechanism 904 is fixedly connected to the inner wall of the arc-shaped inclined groove 902. The top of the model scraping plate 901 is rotatably connected to an upper round block 905 through a rotating bolt. Wave-shaped flexible plates 906 are fixedly connected to the four sides of the upper round block 905;

[0043] The abrasive mechanism 903 is provided with four and evenly distributed on the inner wall of the annular arc inclined groove 902. The scraping mechanism 904 is provided with four and evenly distributed on the inner wall of the annular arc inclined groove 902. The top of the upper round block 905 is fixedly connected to the bottom of the electric telescopic rod 8. When in use, a matching mold plate 1 is placed into the mold hole 5 of the mold table 3 from the bottom of the mold table 3, and then the elliptical block 2 is manually rotated until its top surface contacts the bottom of the mold plate 1. At this time, the molten metal is poured onto the mold plate 1 in the mold hole 5. After the molten metal cools and solidifies, the elliptical block 2 is rotated again from the bottom of the mold table 3 until the elliptical block 2 is completely separated from the contact with the mold plate 1. At this time, the mold plate 1 will fall downward from the mold hole 5 for discharging. After discharging is completed, the electric telescopic rod 8 is started to push the cleaning device 9 into the mold hole 5 for scraping and cleaning. The driving shaft of the electric telescopic rod 8 pushes the upper round block 905 downward. The downward movement of the upper round block 905 drives the bottom model scraping plate 901 to move downward. The shape of the model scraping plate 901 is set to be consistent with the inner wall of the mold hole 5. The model scraping plate 901 moves downward into the mold hole 5 and slides and scrapes the inner wall of the mold hole 5. When the molten metal poured into the mold hole 5 accidentally overflows the mold hole 5, after the overflowed part solidifies, it is located on the top surface of the mold table 3. When the mold plate 1 is removed from the mold hole 5, the solidified molten metal will not fall downward for discharging. At this time, the downward moving model scraping plate 901 contacts the solidified metal material and applies an increasing pressure to it until the part of the metal material located on the top surface of the mold table 3 is broken and separated from the metal material in the mold hole 5, and then the metal material will fall downward for discharging. The overflowed metal material is separated by being broken by the model scraping plate 901. After the model scraping plate 901 enters the mold hole 5, the abrasive mechanism 903 and the scraping mechanism 904 on the inner wall of the annular arc inclined groove 902 enter the inside of the mold hole 5 together and contact the inner wall of the mold hole 5. The arc edges at the top and bottom of the inner wall of the annular arc inclined groove 902 are both set as bevels. The bevel arc edge setting of the annular arc inclined groove 902 facilitates the pre-storage and sliding of materials. When the model scraping plate 901 moves downward until its top surface is flush with the top surface of the mold table 3, the model scraping plate 901 completely blocks the mold hole 5. At this time, the motor 7 is started to drive the electric telescopic rod 8 to rotate. The rotation of the electric telescopic rod 8 drives the upper round block 905 to rotate. The rotation of the upper round block 905 drives the corrugated soft plate 906 on the outer surface to rotate. The corrugated soft plate 906 is made of a plastic and deformable material. When the corrugated soft plate 906 rotates at a high speed, it extends outward to a nearly flat shape under the action of centrifugal force. When the corrugated soft plate 906 extends to a flat shape and rotates, it pushes the metal slag on the mold table 3 to rotate together. The metal slag slides outward under the action of centrifugal force with the high-speed rotation of the corrugated soft plate 906 until it separates from the top surface of the mold table 3. After the top surface of the mold table 3 is cleaned, the motor 7 is turned off to stop the rotation of the corrugated soft plate 906. After the corrugated soft plate 906 loses the action of centrifugal force, it retracts through the plastic material. The corrugated soft plate 906 retracts to a corrugated shape and its length is less than the radius of the model scraping plate 901.

[0044] For the second embodiment, please refer toFigures 1-9 , the present invention provides a die-casting mold for the production of an electronic throttle: the abrasive mechanism 903 includes an arc-shaped through rod 9031, and a threaded abrasive block 9032 is sleeved and slidably connected to the outer surface of the arc-shaped through rod 9031. Circular through holes 9033 are formed at both ends of the threaded abrasive block 9032, and a corrugated ring 9034 is fixedly connected to the inner wall of the circular through hole 9033. Both ends of the arc-shaped through rod 9031 are fixedly connected to the inner wall of the annular arc inclined groove 902. Four arc-shaped through rods 9031 are provided and evenly distributed on the inner wall of the annular arc inclined groove 902. A plurality of threaded abrasive blocks 9032 are provided and evenly distributed on the arc-shaped through rod 9031. A plurality of corrugated rings 9034 are provided and evenly distributed on the inner wall of the circular through hole 9033;

[0045] The scraping mechanism 904 includes an arc-shaped wave plate 9041. An arc-shaped brush 9042 is fixedly connected to the outer surface of the arc-shaped wave plate 9041. An arc-shaped side hole 9043 is formed at the bottom of the arc-shaped wave plate 9041. The bottom of the arc-shaped wave plate 9041 is fixedly connected to the inner wall of the annular arc chute 902. A plurality of arc-shaped wave plates 9041 are provided and evenly distributed on the inner wall of the annular arc chute 902. A plurality of arc-shaped brushes 9042 are provided and evenly distributed on the outer surface of the arc-shaped wave plate 9041. A plurality of arc-shaped side holes 9043 are provided and evenly distributed at the bottom of the arc-shaped wave plate 9041. When in use, after the model scraping plate 901 enters the die hole 5, the thread grinding block 9032 on the inner wall of the annular arc chute 902 contacts and rubs against the inner wall of the die hole 5. The arc-shaped through rod 9031 fixed to the inner wall of the annular arc chute 902 penetrates through the thread grinding block 9032. The thread grinding block 9032 is provided with a circular through hole 9033 with a radius larger than that of the arc-shaped through rod 9031 to facilitate the rotation of the thread grinding block 9032. The thread grinding block 9032 in contact with the inner wall of the die hole 5 rotates as the model scraping plate 901 moves downward. The thread grinding block 9032 performs a frictional grinding and cleaning on the inner wall of the die hole 5. The thread grinding block 9032 is always in contact with the inner wall of the annular arc chute 902 during rotation. The rotating thread grinding block 9032 transfers the slag accumulated in the annular arc chute 902 out together. Both ends of the waveform ring plate 9034 are respectively arranged on the inner walls of two adjacent circular through holes 9033 and completely block the circular through holes 9033. The waveform ring plate 9034 completely blocks the inner walls of the circular through holes 9033 from both ends. When the model scraping plate 901 moves downward, it drives the arc-shaped wave plate 9041 on the inner wall of the annular arc chute 902 to move together. The arc-shaped wave plate 9041 is always in contact with the inner wall of the die hole 5 during movement. The arc-shaped wave plate 9041 performs a secondary scraping and cleaning on the inner wall of the die hole 5. The arc-shaped brush 9042 on the outer surface of the arc-shaped wave plate 9041 is always in frictional contact with the surface of the thread grinding block 9032. The arc-shaped brush 9042 performs a frictional cleaning on the surface of the rotating thread grinding block 9032. When the thread grinding block 9032 rotates, it drives the arc-shaped brush 9042 and the arc-shaped wave plate 9041 in contact with it to move. When the thread grinding block 9032 rotates, it cooperates with the arc-shaped brush 9042 to move and comb the arc-shaped brush 9042. When the arc-shaped wave plate 9041 moves, the slag, dust and other sundries attached to its surface slide downward along the path of the arc-shaped wave plate 9041. The sliding slag and other sundries are continuously discharged downward from the arc-shaped side hole 9043 along with the movement. When the model scraping plate 901 moves below the die hole 5, the slag, dust and other sundries accumulated in the annular arc chute 902 are discharged obliquely to the outside through the bevel angle.

[0046] When the present invention is in operation, a suitable mold plate 1 is placed into the mold hole 5 of the mold table 3 from the bottom of the mold table 3, and then the elliptical block 2 is manually rotated until its top surface contacts the bottom of the mold plate 1. At this time, the molten metal is poured onto the mold plate 1 in the mold hole 5. After the molten metal cools and solidifies, the elliptical block 2 is rotated again from the bottom of the mold table 3 until the elliptical block 2 is completely separated from the contact with the mold plate 1. At this time, the mold plate 1 will drop downward from the mold hole 5 for discharging. After the discharging is completed, the electric telescopic rod 8 is started to push the cleaning device 9 into the mold hole 5 for scraping cleaning. The driving shaft of the electric telescopic rod 8 pushes the upper circular block 905 downward. The movement of the upper circular block 905 drives the bottom model scraping plate 901 to move downward. The shape of the model scraping plate 901 is set to be consistent with the inner wall of the mold hole 5. The model scraping plate 901 moves downward into the mold hole 5 and slides and scrapes the inner wall of the mold hole 5. When the molten metal poured into the mold hole 5 accidentally overflows the mold hole 5, the solidified part of the overflowed molten metal is located on the top surface of the mold table 3. After the mold plate 1 is removed from the mold hole 5, the solidified molten metal will not drop downward for discharging. At this time, the downward-moving model scraping plate 901 contacts the solidified metal material and applies an increasing pressure to it until the part of the metal material on the top surface of the mold table 3 is broken and separated from the metal material in the mold hole 5, and then the metal material will drop downward for discharging. The overflowed metal material is separated by being broken by the model scraping plate 901. After the model scraping plate 901 enters the mold hole 5, the abrasive mechanism 903 and the scraping mechanism 904 on the inner wall of the arc-shaped inclined groove 902 enter the inside of the mold hole 5 and contact the inner wall of the mold hole 5. The arc edges at the top and bottom of the inner wall of the arc-shaped inclined groove 902 are both set as bevels. The bevel arc edge setting of the arc-shaped inclined groove 902 facilitates the pre-storage and sliding of materials. When the model scraping plate 901 moves downward until its top surface is flush with the top surface of the mold table 3, the model scraping plate 901 completely blocks the mold hole 5. At this time, the motor 7 is started to drive the electric telescopic rod 8 to rotate. The rotation of the electric telescopic rod 8 drives the upper circular block 905 to rotate. The rotation of the upper circular block 905 drives the corrugated soft plate 906 on the outer surface to rotate. The corrugated soft plate 906 is made of a plastic and deformable material. When the corrugated soft plate 906 rotates at a high speed, it extends outward to a nearly flat shape under the action of centrifugal force. When the corrugated soft plate 906 extends to a flat shape and rotates, it pushes the metal slag on the mold table 3 to rotate together. The metal slag slides outward under the action of centrifugal force along with the high-speed rotation of the corrugated soft plate 906 until it detaches from the top surface of the mold table 3. After the top surface of the mold table 3 is cleaned, the motor 7 is turned off to stop the rotation of the corrugated soft plate 906. After the corrugated soft plate 906 loses the action of centrifugal force, it retracts through the plastic material. The corrugated soft plate 906 retracts to a corrugated shape and its length is less than the radius of the model scraping plate 901. After the model scraping plate 901 enters the mold hole 5, the threaded grinding block 9032 on the inner wall of the arc-shaped inclined groove 902 contacts and rubs against the inner wall of the mold hole 5. The arc-shaped through rod 9031 fixed to the inner wall of the arc-shaped inclined groove 902 penetrates through the threaded grinding block 9032.The thread grinding block 9032 is facilitated to rotate by opening a circular through-hole 9033 with a radius larger than that of the arc-shaped through-rod 9031. The thread grinding block 9032 in contact with the inner wall of the die hole 5 rotates as the model scraper 901 moves downward. The thread grinding block 9032 performs frictional grinding and cleaning on the inner wall of the die hole 5. When the thread grinding block 9032 rotates, it is always in contact with the inner wall of the annular arc chute 902. The rotating thread grinding block 9032 transfers the slag accumulated in the annular arc chute 902 out together. Both ends of the corrugated ring piece 9034 are arranged on the inner walls of two adjacent circular through-holes 9033 and completely block the circular through-holes 9033. The corrugated ring piece 9034 completely blocks the inner walls of the circular through-holes 9033 from both ends. When the model scraper 901 moves downward, it drives the arc-shaped wave piece 9041 on the inner wall of the annular arc chute 902 to move together. When the arc-shaped wave piece 9041 moves, it is always in contact with the inner wall of the die hole 5. The arc-shaped wave piece 9041 performs secondary scraping and cleaning on the inner wall of the die hole 5. The arc-shaped brush 9042 on the outer surface of the arc-shaped wave piece 9041 is always in frictional contact with the surface of the thread grinding block 9032. The arc-shaped brush 9042 performs frictional cleaning on the surface of the rotating thread grinding block 9032. When the thread grinding block 9032 rotates, it drives the arc-shaped brush 9042 and the arc-shaped wave piece 9041 in contact with it to move. When the thread grinding block 9032 rotates, it cooperates with the arc-shaped brush 9042 to move and comb the arc-shaped brush 9042. When the arc-shaped wave piece 9041 moves, the slag, dust and other sundries attached to its surface slide downward along the path of the arc-shaped wave piece 9041. The sliding slag and other sundries are continuously discharged downward from the arc-shaped side hole 9043 along with the movement. When the model scraper 901 moves below the die hole 5, the slag, dust and other sundries accumulated in the annular arc chute 902 are discharged outward through the bevel angle.,
