Description

Technical Field

[0001] The utility model relates to the technical field of injection mold processing, in particular to an auxiliary grinding device for injection mold processing. Background Technique

[0002] In the processing of injection molds, various auxiliary grinding devices are needed to improve the processing efficiency and quality. Among them, a grinding wheel grinding machine is a common grinding device.

[0003] The grinding wheel on the grinding wheel grinding machine needs to be replaced regularly. In the prior art, the grinding wheel is generally fixed by means of a cap being tightened. For this fixing method, during the use of the grinding wheel grinding machine, vibrations and impact forces will be generated, and these forces will affect the cap for fixing the grinding wheel, resulting in the cap being prone to loosening. When the grinding wheel becomes loose, the connection between it and the main shaft of the grinding wheel grinding machine will become unstable, thereby affecting the rotational balance of the grinding wheel. This may cause uneven wear of the grinding wheel during use, resulting in problems such as poor surface quality, low processing efficiency, and shortened service life of the grinding wheel.

[0004] Therefore, it is necessary to design an auxiliary grinding device for injection mold processing to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide an auxiliary grinding device for injection mold processing.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-4 , an auxiliary grinding device for injection mold processing, including a frame 1, a rotatable drive shaft 2 is installed on the frame 1, a grinding wheel 3 is installed on the drive shaft 2, two guide blocks are fixed on the drive shaft 2, two guide ports are opened on the grinding wheel 3, two opposite card slots 4 are opened on the grinding wheel 3, and a fixing component and a driving component are arranged on the drive shaft 2.

[0023] The fixing component includes two slots 51, a chamber 52, two card blocks 53, a first sliding plug 54, a first spring 55, a rod body 56 and two connecting rods 57. The two slots 51 and the chamber 52 are both opened on the drive shaft 2, and the two slots 51 are both communicated with the chamber 52. The chamber 52 and the drive shaft 2 are coaxially arranged. The two card blocks 53 are respectively slidably connected in the two slots 51. The first sliding plug 54 is hermetically slidably connected to the inner surface of the chamber 52. One end of the first spring 55 is connected to the inner surface of the chamber 52, and the other end is connected to the first sliding plug 54. The rod body 56 is fixed on the first sliding plug 54. One end of each of the two connecting rods 57 is rotatably connected to the rod body 56, and the other end of each of the two connecting rods 57 is respectively rotatably connected to the two card blocks 53. During the process of the drive shaft 2 driving the grinding wheel 3 to rotate, the two card blocks 53 will be stuck into the two card slots 4, and the two card blocks 53 and the two card slots 4 can play a role in fixing the grinding wheel 3.

[0024] The driving assembly includes a plurality of sealing cylinders 61, a plurality of second sliding plugs 62, a plurality of second springs 63 and a plurality of connecting pipes 64. The plurality of sealing cylinders 61 are all fixed on the driving shaft 2, and the plurality of sealing cylinders 61 are circumferentially and arrayedly distributed on the driving shaft 2. The plurality of second sliding plugs 62 are respectively and sealingly slidably connected to the inner surfaces of the plurality of sealing cylinders 61. One ends of the plurality of second springs 63 are respectively connected to the inner surfaces of the plurality of sealing cylinders 61, and the other ends are respectively connected to the plurality of second sliding plugs 62. One ends of the plurality of connecting pipes 64 are respectively communicated with the plurality of sealing cylinders 61, and the other ends are all communicated with the chamber 52. When the grinding wheel 3 stops rotating, the plurality of second sliding plugs 62 will reset under the action of the plurality of second springs 63, which enables the gas to flow back into the chamber 52 again. At this time, the first sliding plug 54 will also reset under the action of the first spring 55, and the two clamping blocks 53 will also approach each other and respectively move out of the two clamping grooves 4. Therefore, when the grinding wheel 3 is not rotating, the staff can directly remove the grinding wheel 3 from the driving shaft 2, which is convenient for quickly replacing the grinding wheel 3.

[0025] The specific working principle of the present utility model is as follows:

[0026] When the auxiliary grinding device for injection mold processing proposed by the present utility model is in use, when installing the grinding wheel 3, the staff sleeved the grinding wheel 3 on the driving shaft 2, aligned the two guiding blocks with the two guiding grooves. Then, a limiting ring is provided on the driving shaft 2. When the grinding wheel 3 contacts the limiting ring, the two clamping grooves 4 are exactly opposite to the two clamping blocks 53. Then, the staff starts the grinding machine, so that the driving shaft 2 drives the grinding wheel 3 to rotate. When the driving shaft 2 rotates, it can also drive the plurality of sealing cylinders 61 to rotate. Under the action of centrifugal force, the plurality of second sliding plugs 62 all move towards the direction away from the driving shaft 2 of the sealing cylinders 61. When the plurality of second sliding plugs 62 move, they can pump the air between the chamber 52 and the first sliding plug 54 into the plurality of sealing cylinders 61. When the air between the chamber 52 and the first sliding plug 54 is pumped out, the first sliding plug 54 moves under the action of negative pressure and drives the rod body 56 to move. When the rod body 56 moves, it can drive the two clamping blocks 53 to move away from each other through the two connecting rods 57, so that the two clamping blocks 53 are respectively inserted into the two clamping grooves 4. Based on the above process, during the process of the driving shaft 2 driving the grinding wheel 3 to rotate, the two clamping blocks 53 are clamped into the two clamping grooves 4, and the two clamping blocks 53 and the two clamping grooves 4 can play a role in fixing the grinding wheel 3. When the grinding wheel 3 stops rotating, the plurality of second sliding plugs 62 will reset under the action of the plurality of second springs 63, which enables the gas to flow back into the chamber 52 again. At this time, the first sliding plug 54 will also reset under the action of the first spring 55, and the two clamping blocks 53 will also approach each other and respectively move out of the two clamping grooves 4. Therefore, when the grinding wheel 3 is not rotating, the staff can directly remove the grinding wheel 3 from the driving shaft 2, which is convenient for quickly replacing the grinding wheel 3.

[0027] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
