How to improve the quality of zinc alloy die-casting molds
The alloys used in die castings of die casting molds are mainly non-ferrous alloys. As for ferrous metals (steel, iron, etc.), due to mold materials and other issues, they are currently seldom used. Aluminum alloys are widely used in non-ferrous alloy die castings, followed by zinc alloys. In order to improve the quality of zinc alloy die-casting molds, which aspects should be taken from?
[Die-casting mold] What aspects should be taken to improve the quality of zinc alloy die-casting molds
Due to the basic reasons that mold quality affects product quality, output, and cost, how can molds be produced with high precision, low cost, and high efficiency for a longer time and more molds? Parts are a major issue. When the mold structure is planned, try to be as compact as possible and easy to operate, and ensure that the mold parts have sufficient strength and rigidity; when the mold structure is allowed, the corners of the mold parts should be planned as rounded transitions as much as possible to prevent stress gathering ; In the planning, the scale of disassembly and assembly must be reduced when repairing a certain part, especially when the vulnerable parts are replaced, the scale of disassembly and assembly must be reduced as much as possible.
The mold making process is also a major part of ensuring the quality of the mold. The processing method and processing accuracy in the mold making process will affect the service life of the mold. The accuracy of each part directly affects the overall condition of the mold. In addition to the accuracy of the equipment itself, it is necessary to improve the processing methods of the parts and improve the technical level of the fitter in the mold grinding process to improve the processing accuracy of the mold parts. . The accurate use and protection of the mold is a major factor in improving the quality of the mold. The device debugging method of the mold should be appropriate. Under the condition of a warm runner, the power supply wiring must be accurate, and the cooling water circuit must meet the planning requirements. The mold is in production. The injection molding machine, The parameters of the die-casting machine and the press must be consistent with the planning requirements and so on.
