[0002] Molds are very common in industrialized factories. There are many ways to produce molds, such as hot processing, casting, stamping, etc. Stamping is one of the most commonly used methods. The mold surface formed by stamping will have burrs, which need to be polished before it can be put into use. A grinding device will be used. However, the existing stamping mold grinding device has the following problems:

[0003] Existing stamping die grinding devices all place the die stamping parts on a workbench, fix them, and then grind and remove burrs. However, when using a grinder to remove burrs on the die, a large amount of dust will be generated. The dust includes solid metal powder, grinder debris, or a mixture of the two. During work, if the dust is not cleaned, the dust will not only cause serious harm to the safety of the workers, but also pollute the air, causing inconvenience for the workers to operate and impair their vision, thereby reducing the yield rate of mold production.

[0007] When the molds need to be polished in batches, the mold is driven by the control component to polish the mold, and then the air in the box is extracted through the dust suction component and the air outlet, and then the gas in the air is drawn in through the dust suction component and the air inlet, so as to achieve the purpose of dust removal and dust collection. Then, during the polishing process, the cleaning component will continue to work to remove the dust adhering to the inner wall of the box door, so that the staff can observe the polishing process more clearly and prevent accidents during the polishing process of the mold.

The rotation of the reciprocating screw will cooperate with the sliding rod to drive the brush to move along the direction of the axis of the reciprocating screw, thereby achieving the purpose of cleaning the glass box door. This will enable the staff to observe the polishing process more clearly and prevent accidents, thereby improving the yield rate of mold production.

[0015] The above-mentioned technical solution is adopted. In this solution, when the air containing dust enters the cylinder body through the air outlet and the second air inlet, the reciprocating motion of the piston plate will send the air containing dust into the collection box through the second air outlet and the air vent.

[0019] By adopting the above technical solution, a filter is fixedly connected to the inside of the first air inlet, which can intercept some impurities in the air and prevent the impurities from entering and affecting the operation of the device.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

When the motor is started, electricity will be transmitted to the rotating shaft to drive the rotating shaft to rotate. Then the rotation of the rotating shaft will drive the cam fixedly connected thereto to rotate. The rotation of the cam will come into contact with the pressure plate, thereby driving the piston plate to reciprocate with the cooperation of the spring. At this time, the reciprocating motion of the piston plate will cooperate with the second air inlet and the air outlet to draw the air with dust from the box into the collection assembly, and at the same time, the air outside the box will be drawn into the box through the first air inlet, the first air outlet and the air inlet. In this way, not only the dust generated by grinding in the box can be collected, but also the air entering the box from the outside can reduce the temperature of the mold when it is working.

[0037] When the starting motor 6 is working, it will transmit electricity to the rotating shaft to drive the rotating shaft to rotate, and then the rotation of the rotating shaft will drive the cam 19 fixedly connected to it to rotate. The rotation of the cam 19 will contact with the pressure plate 17, thereby driving the piston plate 15 to reciprocate with the cooperation of the spring 38. At this time, the reciprocating motion of the piston plate 15 will cooperate with the second air inlet 22 and the air outlet 12 to draw the dusty air from the box body 2 into the collection assembly, and at the same time, the air outside the box body 2 is drawn into the box body 2 through the first air inlet 20, the first air outlet 21 and the air inlet 11. In this way, not only can the dust generated by grinding in the box body 2 be collected, but the air entering the box body 2 from the outside can also reduce the temperature of the mold when it is working.

[0038] like Figure 5As shown, preferably, the control component includes a base 24, a transmission shaft 25 is rotatably connected inside the base 24, a rotating motor 26 is fixedly connected to the box body 2, the output end of the rotating motor 26 is fixedly connected to the transmission shaft 25, a gear 27 is fixedly connected to the transmission shaft 25, the gear 27 is symmetrically arranged, and racks 28 are fixedly connected to the first movable plate and the second movable plate 8, the racks 28 are symmetrically arranged, and the racks 28 are meshed with the gears 27.

[0039] When grinding is required, the rotating motor 26 can be started. The rotating motor 26 will change the distance between the first movable plate and the second movable plate 8 through the mutual cooperation between the gear 27 and the rack 28, so that the mold grinding mold 10 can be controlled more accurately, thereby improving the yield rate of the mold 10 production.

[0040] like Figure 3 As shown, preferably, the cleaning component includes a reciprocating screw 29, which is rotatably connected to the box body 2, one end of the reciprocating screw 29 is fixedly connected to the second pulley 30, the first pulley, the second pulley 30 and the transmission pulley are connected via a belt drive, a sliding rod 32 is fixedly connected inside the box body 2, a brush 31 is threadedly connected to the reciprocating screw 29, and the end of the brush 31 away from the reciprocating screw 29 is slidably connected to the sliding rod 32.

[0041] When the starting motor 6 rotates, the belt and the pulley will cooperate with each other to drive the reciprocating screw 29 fixedly connected to the two pulleys to rotate. The rotation of the reciprocating screw 29 will cooperate with the slide rod 32 to drive the brush 31 to move along the axis of the reciprocating screw 29, thereby achieving the purpose of cleaning the glass door 3. This will enable the staff to observe the polishing process more clearly and prevent accidents, thereby improving the yield rate of the mold 10 production.

[0042] like Figure 2 As shown, preferably, the collecting assembly includes a collecting box 33 , a vent 34 is fixedly connected to the top of the collecting box 33 , a protective net 35 is fixedly connected to the top of the collecting box 33 , and a collector 37 is slidably connected inside the collecting box 33 .

[0043] When the dusty air enters the cylinder 14 through the air outlet 12 and the second air inlet 22, the reciprocating motion of the piston plate 15 will send the dusty air into the collection box 33 through the second air outlet 23 and the air vent 34, and the air will overflow through the protective net 35, and the dust will remain in the collector 37, thereby achieving the purpose of collecting dust.

[0044] like Figure 1 As shown, based on Example 1, the utility model provides a technical solution: preferably, the rack 28 is fixedly connected with limited position teeth.

[0045] In this embodiment, a limit tooth is fixedly connected to one end of the rack 28 because when the rack 28 and the gear 27 are meshed with each other, overload of the gear 27 may cause the rack 28 and the gear 27 to be disengaged, thereby affecting the working efficiency of the device.

[0046] like Figure 2 As shown, based on Example 2, the utility model provides a technical solution: preferably, a filter is fixedly connected to the interior of the first air inlet 20 .

[0047] In this embodiment, a filter is fixedly connected to the inside of the first air inlet 20 to intercept some impurities in the air, thereby preventing the impurities from entering and affecting the operation of the device.

[0048] The working principle of the batch grinding device for processing the stamping die 10 will be described in detail below.

[0049] like Figure 1-5As shown, when the mold 10 needs to be polished in batches, the mold 10 is polished by driving the mold through the control component, and then the air in the box 2 is extracted through the dust suction component and the air outlet 12, and then the gas in the air is sucked in through the dust suction component and the air inlet 11, so as to achieve the purpose of dust removal and dust collection, and then in the process of polishing, the cleaning component will keep working to remove the dust adhering to the inner wall of the box door 3, so that the staff can observe the polishing process more clearly and prevent accidents from happening to the mold 10 during the polishing process. When the starter motor 6 is working, it will transmit electricity to the rotating shaft to drive the rotating shaft to rotate, and then the rotation of the rotating shaft will drive the cam 19 fixedly connected thereto to rotate, and the rotation of the cam 19 will contact the pressure plate 17, thereby driving the piston plate 15 to reciprocate under the cooperation of the spring 38. At this time, the reciprocating motion of the piston plate 15 will cooperate with the second air inlet 22 and the air outlet 12 to extract the air with dust from the box body 2 to the collection assembly, and at the same time, the air outside the box body 2 will be sucked into the box body 2 through the first air inlet 20, the first air outlet 21 and the air inlet 11. In this way, not only can the dust generated by grinding in the box body 2 be collected, but the air entering the box body 2 from the outside can also reduce the temperature of the mold when it is working. When grinding is required, the rotating motor 26 can be started, and the rotating motor 26 will change the distance between the first moving plate and the second moving plate 8 through the mutual cooperation between the gear 27 and the rack 28, so that the mold grinding mold 10 can be more accurately controlled, thereby improving the yield rate of the mold 10 production. When the starter motor 6 rotates, the reciprocating screw 29 fixedly connected to the two pulleys will rotate through the cooperation between the belt and the pulley. The rotation of the reciprocating screw 29 will cooperate with the slide bar 32 to drive the brush 31 to move along the axis of the reciprocating screw 29, thereby achieving the purpose of cleaning the box door 3 made of glass material. This will enable the staff to observe the grinding process more clearly, prevent accidents, and thus improve the yield rate of the mold 10. When the air with dust enters the cylinder body 14 through the air outlet 12 and the second air inlet 22, the reciprocating motion of the piston plate 15 will send the air with dust into the collection box 33 through the second air outlet 23 and the vent 34, and the air will overflow through the protective net 35, and the dust will remain in the collector 37, thereby achieving the purpose of collecting dust. The reason why the limited position teeth are fixedly connected at one end of the rack 28 is that when the rack 28 and the gear 27 are meshed with each other, the gear 27 movement overload may cause the rack 28 and the gear 27 to be de-toothed, thereby affecting the working efficiency of the device. By fixing a filter screen inside the first air inlet 20, some impurities in the air can be intercepted to prevent the impurities from entering and affecting the operation of the device.

[0050] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
