The application of laser surface hardening technology in mold manufacturing can integrate design, material selection, mold making, inspection, repair and other technologies, greatly shortening the design and manufacturing cycle, reducing production costs, changing mold manufacturing methods, and finally integrating and improving the entire mold industry Level. The cross-section of the cooling channel is larger than 5mm. The positive pole of the power supply is connected to a plating pen as the anode during brush plating; the negative pole of the power supply is connected to the workpiece as the cathode during brush plating. The plating pen usually uses high purity The fine graphite block is used as the anode material, and the graphite block is wrapped with cotton and a wear-resistant polyester cotton sleeveIn addition, the increasing demand for advanced and complex high-end metal cutting machine tools (especially machining centers and compound machine tools) will further increase the sales of machine tool products.A few days ago, according to a study by Freedonia Group, an international industry research organization, China’s demand for machine tools will grow steadily at an annual growth rate of 9.7 per year, mainly due to the expected strong growth in the automotive, shipbuilding, aerospace, and power transmission and distribution industries.. Another driving factor for the growth in demand for machine tools can be attributed to the transition to using more environmentally friendly machine toolsAfter reducing the Blood collection mould of the coating, the influence of hot spots is weakened and the local cooling capacity of the mold is improved. , And even make the temperature difference gradually decrease, and then tend to stabilize; and when the mold wall thickness is large, the heat released by the alloy during solidification and cooling is the same, but at this time due to the increase of the mold wall thickness, the heat transfer As the capacity decreases, the temperature difference will gradually increase. The main reason is that the cooling capacity of the mold is affected by the comprehensive effect of its heat storage capacity and thermal conductivity
