It can help operators to accurately control key indicators such as arc radius, center position and contour smoothness. It is widely used in machining scenarios with complex arc structures such as precision die cavities and cores.

[0003] When milling the arc surface in the mold groove, the generated iron filings will accumulate in the arc groove. The iron filings move at high speed under the drive of the cutting tool, scratching the side wall or bottom of the groove, damaging the surface roughness. At the same time, the scratches will become stress concentration points, indirectly affecting the dimensional stability of subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when existing milling machines mill the arc surface in the groove of a mold, the iron filings generated will accumulate in the arc groove, and the iron filings will move at high speed under the drive of the cutting tool, scratching the side wall or bottom surface of the groove, damaging the surface roughness, and the resulting scratches will become stress concentration points. Therefore, an auxiliary device for improving the accuracy of arc milling in molds is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mold milling arc machining accuracy auxiliary device, comprising a machining table, the machining table being fixedly installed on the drive end of a dual-axis adjuster, a mold holder and an arc groove chip removal auxiliary component being fixedly installed on the top surface of the machining table, the arc groove chip removal auxiliary component being disposed on one side of the mold holder, the arc groove chip removal auxiliary component comprising a mounting frame, a wind-powered impurity remover and a rotation adjustment component, an adjustment groove being provided inside the mounting frame, the wind-powered impurity remover being rotatably connected inside the adjustment groove, and the drive end of the rotation adjustment component being drively connected to one side of the wind-powered impurity remover.

[0006] Preferably, the wind-powered impurity remover includes a rectangular frame, a rotating shaft, two air outlet slots, and an air storage chamber. The rotating shaft is fixedly installed in the middle of the rectangular frame, and the two air outlet slots are symmetrically fixedly installed inside the rectangular frame. One end of each air outlet slot is fixedly connected to one end of the air storage chamber.

[0007] Preferably, the rotation adjustment assembly includes a drive assembly, a drive gear, and a transmission gear.

[0009] Preferably, the other end of the air storage chamber is fixedly connected to an air supply pipe.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, high-pressure gas is blown into the interior of the air-powered impurity remover by a blower and blown out from the air outlet of the air-powered impurity remover to blow out the iron filings inside the arc groove. This prevents the iron filings from accumulating inside the arc groove for a long time, ensuring that the cutting tool can accurately process the interior of the arc groove without being disturbed by the iron filings. After the iron filings are removed in time, the side wall and bottom surface of the processed arc groove will not have defects such as scratches or dents due to the scraping of the iron filings, ensuring that the surface roughness meets the high precision requirements of the mold.

[0011] 2. In this utility model, the drive motor drives the speed changer to work, and the speed changer drives the drive gear to rotate. Under the transmission of the transmission gear, the rotating shaft drives the rectangular frame to adjust the angle, so that the output end of the air outlet slot is adjusted accordingly. Iron filings are removed from the inside of the arc slot at fixed points, and the high-pressure airflow is directed to the dead corner, avoiding the problem of iron filings remaining in some areas under the traditional fixed air outlet method, and ensuring the cleanliness of each position in the arc slot.

Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an auxiliary device for milling arc machining accuracy of molds, including a machining table 1. The machining table 1 is fixedly installed on the drive end of the dual-axis adjuster 2. A mold holder 3 and an arc groove chip removal auxiliary component 4 are fixedly installed on the top surface of the machining table 1. The arc groove chip removal auxiliary component 4 is located on one side of the mold holder 3.

The drive end of the rotation adjustment component 43 is connected to one side of the wind-powered impurity remover 42.

[0017] The specific settings and functions of this embodiment are described below. When the milling machine processes the mold, iron filings will accumulate inside the arc groove. At this time, the blower blows high-pressure gas into the interior of the air-powered impurity remover 42 and blows it out from the air outlet of the air-powered impurity remover 42 to blow out the iron filings inside the arc groove. This prevents the iron filings from accumulating inside the arc groove for a long time, ensuring that the tool can accurately process the interior of the arc groove without being disturbed by the iron filings. After the iron filings are removed in time, the side wall and bottom surface of the processed arc groove will not form scratches, dents or other defects due to the scraping of iron filings, ensuring that the surface roughness meets the high precision requirements of the mold and reducing the workload of subsequent remedial processes such as grinding and polishing.

[0018] Example 2: Figure 1 - Figure 4As shown, the auxiliary device for milling arcs in molds according to this utility model includes a machining table 1, which is fixedly installed on the drive end of a dual-axis adjuster 2. A mold holder 3 and an arc groove chip removal auxiliary component 4 are fixedly installed on the top surface of the machining table 1.

The rotating shaft 422 is fixedly installed on the top surface of the machining table 1. The rotating adjustment assembly 43 includes a drive assembly 431, a drive gear 432, and a transmission gear 433. The drive end of the drive assembly 431 is fixedly connected to the center of the drive gear 432. The drive gear 432 and the transmission gear 433 mesh with each other.

[0019] The overall effect of this embodiment is that high-pressure gas enters the air storage chamber 424 through the air supply pipe, and then enters the two air outlet slots 423 through the air storage chamber 424 to blow away the iron filings inside the arc slots. When it is necessary to adjust the air outlet position of the air outlet slot 423, the drive motor drives the speed changer to work, and the speed changer drives the drive gear 432 to rotate. Under the transmission of the transmission gear 433, the rotating shaft 422 drives the rectangular frame 421 to adjust the angle, so that the output end of the air outlet slot 423 is adjusted accordingly, and the iron filings inside the arc slot are removed at fixed points. The high-pressure airflow is directed to the dead corner, avoiding the problem of iron filings remaining in some areas under the traditional fixed air outlet method, and ensuring the cleanliness of each position in the arc slot.

[0020] The usage and working principle of this device: When the milling machine processes the mold, the iron filings will accumulate inside the arc groove. At this time, the blower blows high-pressure gas into the interior of the air-powered impurity remover 42 and blows it out from the air outlet of the air-powered impurity remover 42 to blow out the iron filings inside the arc groove, so as to avoid the iron filings accumulating inside the arc groove for a long time and ensure that the tool can accurately process the interior of the arc groove.

[0021] High-pressure gas enters the air storage chamber 424 through the air supply pipe, and then enters the two air outlet slots 423 through the air storage chamber 424 to blow away the iron filings inside the arc slots. When it is necessary to adjust the air outlet position of the air outlet slot 423, the drive motor drives the speed changer to work, and the speed changer drives the drive gear 432 to rotate. Under the transmission of the transmission gear 433, the rotating shaft 422 drives the rectangular frame 421 to adjust the angle, so that the output end of the air outlet slot 423 is adjusted accordingly, and the iron filings inside the arc slot are removed at a fixed point.
