Description
Technical Field
[0001] The utility model belongs to the technical field of mold polishing, and particularly relates to a mold polishing device. Background Art
[0002] A mold polishing device refers to a mechanical device used for fine processing of the mold surface to improve its smoothness and accuracy. These devices usually include various types of polishing machines, auxiliary tools, and control systems, and can achieve efficient and high-quality polishing effects. The selection of mold polishing equipment should be determined according to specific polishing requirements, the complexity of the workpiece, and the surface quality standards to be achieved.
[0003] If the mold is unstable during the polishing process, over-polishing and under-polishing phenomena may occur, which are usually caused by unstable operation. The over-polishing phenomenon refers to the situation where the mold surface becomes overly smooth, even with micro-cracks or deformation, affecting the accuracy and service life of the mold, due to excessive polishing time, excessive polishing pressure, or improper use of the polishing tool. Therefore, how to keep the mold at the desired angle and stability during the polishing process is very important for mold polishing. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a mold polishing device that can improve work convenience and comfort by adjusting the front-back position and tilt angle of the mold.
[0005] The described mold polishing device includes a base, on which an air source is installed. The air outlet end of the air source is connected to a pneumatic grinding machine. A bottom plate is arranged on the base on the right side of the air source. The bottom plate is in a front-back sliding fit connection with the base. The right end of the bottom plate is hinged with a fixing plate. The right end of the fixing plate is hinged with the bottom plate, and the left end can swing up and down. Hydraulic cylinders are hinged on the front sides of the bottom plate and the fixing plate respectively. The cylinder bodies of the two hydraulic cylinders are hinged on the bottom plate and the fixing plate respectively, and the piston rods of the two hydraulic cylinders are hinged;
[0006] When the piston rod of the hydraulic cylinder hinged to the bottom plate shortens and the piston rod of the hydraulic cylinder hinged to the fixing plate elongates, the left end of the fixing plate swings upward;
[0007] Two clamping plates are arranged on the bottom plate at left-right intervals. From left to right, they are the first clamping plate and the second clamping plate. The second clamping plate is fixed to the right end of the fixing plate. The first clamping plate can move left and right along the fixing plate. A cylinder for driving the first clamping plate to move left and right is connected to the left side of the first clamping plate. The piston rod of the cylinder is connected to the first clamping plate;
[0008] A drawer in a drawer-type fit is installed at the right end of the base.
[0009] The air cylinder drives the first clamping plate to move to the right. The first clamping plate and the second clamping plate clamp the mold on the fixed plate, and can clamp molds of different models. By adjusting the up and down swing of the left end of the fixed plate through the hydraulic cylinder, the inclination of the fixed plate can be adjusted, which is convenient for further processing the mold from different angles. Slide the bottom plate back and forth to facilitate adjusting the distance between the mold and the operator, and further facilitate different operators to adjust the distance during mold processing; the drawer is convenient for storing items such as sanding paper and polishing agent.
[0010] Furthermore, a guide rail is longitudinally fixed on the base, and a slider that is slidably engaged with the guide rail in the front-back direction is fixed to the bottom of the bottom plate.
[0011] By sliding the slider along the guide rail back and forth, it is convenient to adjust the bottom plate back and forth.
[0012] Furthermore, columnar bosses are longitudinally fixed on the front and back sides of the bottom plate and the fixed plate. The bosses are hinged to the corresponding hydraulic cylinders through bearings. The boss on the fixed plate is the first boss, and the boss on the bottom plate is the second boss.
[0013] The bearing is fixed on the cylinder block of the corresponding hydraulic cylinder, and the first boss and the second boss are respectively inserted into the bearings on the corresponding hydraulic cylinders to achieve the hinge connection.
[0014] Furthermore, a first sleeve is longitudinally fixed to the right end of the fixed plate, and a second sleeve is longitudinally fixed to the bottom plate corresponding to the first sleeve. The first sleeve and the second sleeve are hinged through a pivot.
[0015] The first sleeve and the second sleeve are hinged together through a pivot, which not only realizes the up and down swing of the left end of the fixed plate, but also supports the right end of the fixed plate, making the fixed plate more stable during the up and down swing process.
[0016] Furthermore, a slot for mounting a pneumatic sander is fixed on the base on the right side of the bottom plate.
[0017] The slot is convenient for storing the pneumatic sander.
[0018] Furthermore, a hydraulic pump is installed on the base in front of the air source.
[0019] The output end of the hydraulic pump is connected to the input end of the hydraulic cylinder through a pipeline, thereby driving the piston rod of the hydraulic cylinder to extend and retract.
[0020] Furthermore, two sets of the guide rails and the sliders are arranged at intervals left and right.
[0021] The two sets of guide rails and sliders make the fixed plate more stable during the front-back sliding process.
[0022] Compared with the prior art, the utility model has the following beneficial effects:
[0023] The air cylinder drives the first clamping plate to move to the right. The first clamping plate and the second clamping plate clamp the mold on the fixed plate. Different types of molds can be clamped. By adjusting the front-back position and tilt angle of the mold, the work convenience and comfort can be improved. The tilt of the fixed plate is adjusted by the hydraulic cylinder to swing the left end of the fixed plate up and down, so as to adjust the tilt of the fixed plate, which is convenient for further processing the mold from different angles. The bottom plate slides back and forth to facilitate adjusting the distance between the mold and the operator, and further facilitates different operators to adjust the distance during mold processing; the drawer is convenient for storing items such as sanding paper and polishing agent.

[0060] As shown in Figure 1 and Figure 4 shown, a clamping groove 10 is welded on the right side of the top of the base 13. The clamping groove 10 is mainly used for clamping the pneumatic grinding machine 9. The clamping groove 10 with a "C"-shaped or square cross-section can be made according to the outer shape structure of the pneumatic grinding machine 9.
[0061] Step 2: Installation
[0062] As shown in Figure 1 shown, the hydraulic pump 17 and the air source 18 are installed at intervals front and back on the left side of the top of the base 13. As shown in Figure 3 shown, the air source 18 is installed at the rear side of the hydraulic pump 17, and the pneumatic grinding machine 9 is placed on the clamping groove 10;
