After the wear of the guide sleeve of the mold ejector pin, the resistance of the ejector pin movement increases, leading to bending and jamming, and the product ejector rate exceeds 15%. Daokedao adopts inner hole melting technology to melt Ni-P alloy coating on the inner hole of the guide sleeve, with a hardness of HRC55-58, a surface roughness of Ra0.06 μ m, and a 40% reduction in the resistance of the ejector pin movement. After repair, the clearance between the guide sleeve and the ejector pin is controlled at 0.005-0.01mm, and the bending rate of the ejector pin is reduced from 10% to 0.5%. The equipment is equipped with batch repair fixtures for guide sleeves, and a single shift can repair 50 sets, with a repair cost of only 20% of the new set. After being applied in a certain toy factory, the top injury rate of the product has decreased to 1%, the cost of replacing the top pin has been reduced by 80%, and the downtime of the mold has been shortened by 70%.
