In this paper the lightweight design of grout mold bracket for forming equipment of pulp molding product was made by using the finite element analysis software Ansys. First, the parametric finite element model of bracket was built by APDL and the static analysis was carried out. The result showed that there was great surplus of strength on the bracket and latent capacity to be lightened. And then the allowable stress of the bracket was set as the state variable and the total mass of the bracket as the optimizing target, the first order optimization method was used to make the lightweight design based on Ansys Design Opt module. After optimization, the total mass of the bracket reduced by 33%, saving the cost of production. This research proposed the optimizing design scheme of grout mold bracket for forming equipment of pulp molding product.
