Manufacturer's requirements for mold making and material hardness

Sep 19, 2018

Stretching mold processing can produce various types of molds of different specifications and models, including ceramic molds. In the actual production process, materials must first be selected. The materials used in the processing of tensile molds are wear-resistant and high. Toughness and corrosion resistance can greatly enhance the service life of the mold.


Good ceramic mold structure design is based on the premise of a qualified tensile mold manufacturing, using qualified equipment, including CNC milling, EDM, fine carving, large drilling and wire cutting, milling machines and lathes for surface grinders, etc. . Many products must be used in the production of stamping dies or special-shaped molds, school molds and other molds produced with quality is very good.


For the processing on the mold, the hardness of the conjugate gear is the same as that of the contract tensile mold; for the stretch mold processing, the minimum hardness of the spur gear small gear should be 20-25HB higher than the maximum hardness of the conjugate gear. The minimum hardness of the pinion should be 40-50HB higher than the maximum hardness of the conjugate gear.


For the soft-hard tooth surface fit, if the pinion gear is surface-quenched, the large gear can be treated with nitriding, carburizing, etc. Taking the turbine reducer as an example, the hardness of the drive gear shaft is 285-320HB, the driven gear The hardness is 245-285HB.


These are all about mold making and material hardness requirements. They can be used as a reference for users to select materials and operating techniques to ensure that a qualified mold can be produced to provide a good foundation for producing high quality products.http://www.yxhgmould.com/
