Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3 The present invention discloses a precision grinding device for mold production. A motor 101 is fixedly connected to the bottom wall of the inner cavity of the outer shell 100, which drives the transmission shaft 102 to rotate. The transmission shaft 102 is rotatably connected to the bottom end of the outer shell 100, which drives the grinding head 103 to rotate. The top end of the transmission shaft 102 meshes with the output end of the motor 101, and the bottom end of the transmission shaft 102 is fixedly connected to the grinding head 103, which facilitates the grinding of the mold. For fine grinding, a fixed tube 104 is fixedly connected to the bottom end of the outer casing 100. The fixed tube 104 facilitates the limiting and guiding of the movement of the telescopic tube 105. The telescopic tube 105 is slidably connected to the inner wall of the fixed tube 104, allowing the telescopic tube 105 to slide within the inner wall of the fixed tube 104. A dust cover 106 is fixedly connected to the bottom wall of the telescopic tube 105, covering the area being ground by the grinding head 103 to prevent grinding debris and dust from flying. This facilitates subsequent suction cleaning. The outer wall of the dust cover 106 is evenly provided with suction ports, allowing for comprehensive dust suction and effectively preventing dust leakage. The suction ports facilitate dust extraction. A suction ring 107 is installed on the outer wall of the dust cover 106, allowing for the extraction of dust from the suction ports. A suction pipe 108 is fixedly connected to the top wall of the suction ring 107, facilitating the extraction of dust from the suction ring 107. The device is designed with a flexible hose for easy bending. A push spring 109 is fixedly connected to the bottom wall of the outer casing 100. The push spring 109 facilitates the movement of the dust cover 106, ensuring that the dust cover 106 always presses against the mold surface for protection. The bottom end of the push spring 109 is located on the top wall of the dust cover 106. The device can be installed on a position adjustment mechanism, which allows for easy adjustment of the device's position. This facilitates automatic precision grinding of the mold and improves the device's practicality.

[0021] In this embodiment: the mold to be processed is fixedly placed on the processing table, the dust suction pipe 108 is connected to the air pump, and the handheld device 100 is used for fine grinding. The motor 101 drives the transmission shaft 102 to rotate, and the transmission shaft 102 drives the grinding head 103 to rotate. The handheld device moves the grinding head 103 to the surface of the mold for grinding. The push spring 109 pushes against the dust cover 106, which helps to block dust. During grinding, the dust cover 106 is pressed against the surface of the mold. The dust suction pipe 108 sucks the inner wall of the dust suction ring 107, and the dust suction ring 107 sucks the air in the dust suction port. The dust generated during grinding is sucked through the dust suction port. This device can easily suck the dust generated at the grinding head 103 in real time, avoid dust leakage during grinding, and facilitate real-time and accurate dust suction at the grinding area.

[0022] The bottom wall of the dust cover 106 is evenly provided with ball grooves, and the inner wall of each ball groove is rotatably connected with a ball bearing 110. The ball bearing 110 facilitates rolling on the outer wall of the mold, avoiding friction and damage.

[0023] In this embodiment: the ball bearing 110 is set to facilitate movement on the surface of the mold, and the dust cover 106 drives the ball bearing 110 to move, so that the dust cover 106 can move with the position change of the grinding head 103. This makes it easy for the dust cover 106 to move with the grinding head 103, so that the dust cover 106 avoids friction on the surface of the mold and damage, which is beneficial to the service life of the device.

[0024] The inner wall of the fixed tube 104 is square, and the outer wall of the telescopic tube 105 matches the inner wall of the fixed tube 104.

[0025] In this embodiment, the inner wall of the fixed tube 104 is square to facilitate the limiting of the lifting and lowering of the telescopic tube 105, preventing the telescopic tube 105 from deflecting. This also helps to limit the lifting and lowering of the dust cover 106, preventing the dust cover 106 from deflecting, and facilitates the stable and smooth cleaning of dust generated during grinding.

[0026] A fastening bracket 111 is fixedly connected to the right side wall of the fixed tube 104. The fastening bracket 111 facilitates the locking and limiting of the vacuum tube 108. The vacuum tube 108 is located on the inner wall of the fastening bracket 111.

[0027] In this embodiment: by setting the fastening bracket 111, it is convenient to fasten and limit the suction pipe 108, so as to prevent the suction pipe 108 from falling off at will and affecting the grinding operation, which is beneficial to the fine grinding operation of the mold, thus demonstrating the practicality of the device.

[0028] The outer wall of the dust cover 106 is provided with a threaded groove. The dust suction ring 107 is screwed to the outer wall of the dust cover 106. A fixing ring 112 is fixedly connected to the outer wall of the dust cover 106. The fixing ring 112 facilitates the limiting and fixing of the rubber ring 113. The bottom wall of the fixing ring 112 is fixedly connected to the rubber ring 113. The rubber ring 113 has elasticity, which facilitates pushing the dust suction ring 107 and provides a reaction force to prevent the dust suction ring 107 from deflecting.

[0029] In this embodiment: rotating the dust suction ring 107 facilitates screwing the dust cover 106, and disassembling the dust suction ring 107 facilitates cleaning and maintenance, which helps to clear the airflow path and facilitates the device to suck up the dust generated during grinding.
