[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides a polishing device for mold manufacturing, such as Figure 1-4 As shown, the polishing device includes a bracket 2 fixedly mounted on an equipment box 1 and a polishing assembly 3 mounted below the bracket 2. A baffle box 4 is provided on the equipment box 1, and a collecting mechanism 6 is provided inside the equipment box 1.

[0029] The lower end of the bracket 2 is provided with a splash-proof mechanism 5;

[0030] The collecting mechanism 6 includes a discharge channel 61 installed inside the equipment box 1 and a negative pressure fan 66 symmetrically arranged outside the discharge channel 61. The upper end of the discharge channel 61 is symmetrically provided with wind grooves 65, and the negative pressure fan 66 is located below the wind grooves 65. The upper end of the discharge channel 61 is provided with a protective component, and the protective component includes a slide rail frame 64 installed at the upper end of the discharge channel 61, and the upper end of the slide rail frame 64 is slidably connected with a cover 67.

[0031] Specifically, the discharge channel 61 is in the shape of a square cone, and the negative pressure fan 66 is installed on the outer side of the upper cone. The wind groove 65 opened in the discharge channel 61 is located at the installation position of the negative pressure fan 66. The slide rail frame 64 installed on the inner side of the discharge channel 61 surrounds the wind groove 65, and the cover 67 is slidably connected to the slide rail frame 64. When the cover 67 is close to the front of the equipment box 1, the wind groove 65 is in an open state. At this time, when the motor of the negative pressure fan 66 is driven, negative pressure will be generated and the debris at the upper end of the equipment box 1 will be adsorbed to the discharge channel 61 through the wind groove 65. When the cover 67 is close to the back of the equipment box 1, the cover 67 seals the wind groove 65. At this time, the coolant can be blocked by the cover 67 when it drips, so as to prevent the coolant from contacting the negative pressure fan 66.

[0032] A limiting slide groove 69 is provided at the upper end of the equipment box 1 , and a limiting guide plate 68 is installed at one end of the cover 67 , and the upper end of the limiting guide plate 68 is slidably connected to the limiting slide groove 69 .

[0033] Furthermore, a limit guide plate 68 is installed at one end of the cover 67 which is at a high position, and the limit guide plate 68 is slidably connected to the limit slide groove 69. The position of the cover 67 can be adjusted by moving the limit guide plate 68 located above the equipment box 1, and the negative pressure wind force can also be adjusted through the covered wind groove 65 area.

[0034] The splash-proof mechanism 5 comprises an articulated seat 54 mounted at the lower end of the bracket 2 and a connecting box 51 arranged at the base of the articulated seat 54 . A spray pipe 52 is mounted at the liquid outlet of the connecting box 51 , and a liquid guide tube 53 is mounted at the tail end of the connecting box 51 .

[0035] It should be noted that the liquid guide tube 53 is interspersed with the equipment box 1, and the bottom is located deep in the coolant. The connecting box 51 is mainly driven by a water pump and sprayed to the polishing area of ​​the workpiece through the spray pipe 52. The sprayed coolant can also avoid the splashing of debris, and play a role in dust and splash prevention.

[0036] A calibration chute 8 is provided on one side of the discharge channel 61 close to the feed chute 63, and the calibration chute 8 is located below the feed chute 63. A filter plate 62 is slidably connected to the calibration chute 8, and the filter plate 62 is movably interlaced with the front of the equipment box 1. A feed chute 63 is provided on the side of the discharge channel 61, and a discharge plate 7 is installed at the feed chute 63.

[0037] Furthermore, the filter plate 62 is aligned with the notch on the front side of the equipment box 1 and pushed in horizontally, and the two sides of the filter plate 62 are respectively located in the calibration chute 8 symmetrically opened in the discharge channel 61. When the filter plate 62 is pushed to the deepest point, the debris mixed into the coolant can be filtered. The filter plate 62 can be pulled outward later to clean up the debris, and after the discharge chute 63 opened in the discharge channel 61 completely covers the wind trough 65 with the cover 67, the negative pressure fans 66 on both sides are started. The generated wind force can accelerate the air circulation inside the equipment box 1, accelerate the drying of the filter plate 62, avoid the filter plate 62 from contacting the debris containing coolant for too long and causing corrosion, and improve the service life of the filter plate 62.

[0038] When in use, it is selected whether to use coolant to cool the polishing assembly 3 according to the different workpieces being polished, a discharge channel 61 is installed inside the equipment box 1, and a negative pressure fan 66 is installed at an inclined position outside the discharge channel 61. When polishing a workpiece, if the polishing workpiece does not need to cool the polishing assembly 3, the limit guide plate 68 is manually pushed to one side so that when the negative pressure fan 66 rotates, the generated debris can be sucked into the equipment box 1 and the discharge channel 61 through the wind slot 65, and the debris falls on the discharge plate 7 through the wind slot 65, and slides from the lower chute 63 to the filter through the inclined discharge plate 7. The coolant is collected at the plate 62. If the polished workpiece needs to use coolant, the limit guide plate 68 is manually moved, and the air groove 65 is sealed by the cover 67 to prevent the coolant and debris from contacting the negative pressure fan 66, thereby providing protection for the negative pressure fan 66. The coolant slides downward through the discharge channel 61, and the debris is filtered and collected by the filter plate 62. The coolant is stored at the bottom of the equipment box 1 through the filter plate 62. Through this collection method, the cover 67 can be flexibly moved according to the type of polished workpiece, to provide protection for the negative pressure fan 66 and increase the service life of the negative pressure fan 66.
