Automation of process of production of molds for manufacture of lip seals

Lip seals are used to ensure the tightness of the executive units of hydraulic systems. An important role for improving tightness is played by form of distribution diagrams of contact stresses, which excludes or reduces possibility of hydrodynamic pressure, as well as providing a return fluid leak in the sealing chamber. Currently used methods of production of contact seals, with the help of injection molds are based on the sizing of the GOST 14896-84 on the seals and the mold. However, the dimensions given in this document often do not guarantee the specified resource because it does not take into account the operating conditions. The paper describes a method of automation of process of production of molds for manufacture of lip seals, through the construction of parametric models of contact-type lip seals, which include the optimization of their design parameters and shape, according to the specific set conditions of subsequent operation, to provide a given guaranteed working capacity resource.
