What are the advantages of surface painting of plastic molding parts? Painting the surface of the plastic injection molding parts can ensure the brightness of the plastic products. Because plastic products themselves are difficult to reflect light. Therefore, the plastic parts look darker. If there are leather lines on the surface of the plastic parts, it will be even darker. Therefore, in order to seek the beautiful appearance of plastic products, a layer of paint will be sprayed on the surface of plastic parts. This ensures the brightness of the plastic products. Painting the surface of plastic parts can reduce the scrap rate of plastic products. The scrap rate of white plastic products has always been a headache in the injection molding industry. If the surface is painted, it will cover up the shortcomings of the products and reduce the scrap rate of the products. Plastic part painting: it is very useful to paint the surface of plastic parts with requirements. But painting is another process for injection molded parts. The cost will be increased. How to solve the problems in plastic molds processing? In the process of processing plastic molds, We are most worried about some common shortcomings, Which will directly lead to the application function of the workpiece and even make the workpiece unable to be used here. Therefore, we must try our best to avoid some deficiencies when processing molds. The following suggestions are provided for this problem: 1.Reasonably select and trim the grinding wheel. The white corundum grinding wheel is better. Its function is hard and brittle, and it is prone to new cutting edges. Therefore, the cutting force is small and the grinding heat is small. It is better to use the medium particle size in the particle size, such as 46 ~ 60 mesh. It is better to select the medium soft (ZR1, Zr2 and R1, R2) in the hardness of the grinding wheel, that is, the grinding wheel with coarse particle size and low hardness, which has good self excitation and can reduce the cutting heat. It is very important to select an appropriate grinding wheel during fine grinding. In view of the high vanadium and molybdenum status of die steel, Gd single crystal corundum grinding wheel is more suitable. When processing cemented carbide and high quenching hardness data, diamond grinding wheel with organic binder is preferred. The grinding wheel with organic binder has good self grinding performance and the workpiece roughness can reach Ra0 two 渭 m. In recent years, with the application of new data, CBN (cubic boron nitride) grinding wheel shows very good machining effect. The effect of finishing machining on NC forming grinder, coordinate grinder and CNC Internal and external grinder is better than that of other kinds of grinding wheels. In the grinding process, pay attention to the timely dressing of the grinding wheel and adhere to the sharpness of the grinding wheel. When the grinding wheel is passivated, it will slip and knead on the surface of the workpiece, resulting in the surface burn of the workpiece and the decrease of strength. 2.The cooling and smoothing liquid shall be reasonably used in die processing, the three effects of cooling, washing and smoothing shall be brought into play, the cooling and smooth cleaning shall be adhered to, and then the grinding heat shall be controlled within the allowable range to avoid thermal deformation of the workpiece. Improve the cooling conditions during grinding, such as selecting oil immersed grinding wheel or internal cooling grinding wheel. When the cutting fluid is introduced into the center of the grinding wheel, the cutting fluid can directly enter the grinding area to play an effective cooling effect and avoid the surface burn of the workpiece. 3.The quenching stress after heat treatment is reduced to the lowest limit. Because the quenching stress and network carbonization are arranged under the effect of grinding force, the phase transformation is arranged, which is very easy to cause cracks in the workpiece. For precision dies, in order to eliminate the residual stress of grinding, low temperature aging treatment should be carried out after grinding to improve the durability. 4.To eliminate grinding stress, the mold can also be immersed in 260 ~ 315 鈩?salt bath for 1.5min, and then cooled in 30 鈩?oil. In this way, the hardness can be reduced by 1hrc and the residual stress can be reduced by 40% ~ 65%. 5.For the precision grinding of precision die with scale tolerance within 0.01mm, attention should be paid to the influence of ambient temperature and constant temperature grinding is required. According to the calculation, when the temperature difference of 300mm long steel parts is 3 鈩? the data is 10.8 渭 About M, (10.8 = 1.2 脳 three 脳 3. 1.2 deformation per 100mm 渭 M / 鈩?, the influence of this factor should be fully considered in each finishing process. 6.Electrolytic grinding is selected to improve the manufacturing accuracy and appearance quality of the die. During electrolytic grinding, the grinding wheel scrapes off the oxide film instead of grinding metal, so the grinding force is small and the grinding heat is small. Grinding burr, crack, burn and other phenomena will not occur. Generally, the surface roughness can be better than Ra0 sixteen 渭 m锛?In addition, the wear of grinding wheel is set to be small. For example, when grinding cemented carbide, the wear amount of silicon carbide grinding wheel is about 400% ~ 600% of the weight of cemented carbide. When electrolytic grinding is used, the wear amount of grinding wheel is only 50% ~ 100% of that of cemented carbide. 7.The grinding quantity shall be reasonably selected, and the fine grinding method with small radial feed and even precision grinding shall be selected. If the radial feed rate and grinding wheel speed are properly reduced and the axial feed rate is increased, the contact area between grinding wheel and workpiece is reduced, the heat dissipation conditions are improved, and then the progress of surface temperature is effectively controlled.
