Description

High-efficient fashioned motorcycle clutch unites die casting die Technical Field The utility model belongs to the technical field of die casting dies, and particularly relates to a high-efficiency formed motorcycle clutch combined die casting die. Background In the production process of the motorcycle clutch, the die casting die is key equipment, the structural design of the die casting die directly influences the production efficiency and the product quality, and the existing motorcycle clutch die casting die has some defects, such as complex die structure, high manufacturing cost, unsmooth demoulding process, influence the production efficiency, poor adaptability to different types of clutches and low die universality. In addition, in the die casting process, the flow of the molten metal is uneven, so that the defects of air holes, shrinkage porosity and the like in the clutch parts are easily caused, and the product quality is influenced. Therefore, a new and efficient molding motorcycle clutch combination die casting mold is needed to solve these problems. Disclosure of utility model The utility model aims to provide an efficient formed motorcycle clutch combined die-casting die, which solves the problems of complex die structure, difficult demoulding, poor universality, unstable product quality and the like in the prior art. By optimizing the die structure, the production efficiency and the product quality are improved, and the production cost is reduced. In order to achieve the above purpose, the technical scheme adopted by the utility model for solving the technical problems is as follows: The utility model provides a high-efficient fashioned motorcycle clutch unites die casting die, includes upper die base and die holder, upper die base bottom fixedly connected with goes up the mould benevolence, die holder top fixedly connected with lower mould benevolence, go up the mould benevolence and form the die cavity after the die closing of lower mould benevolence, be equipped with in the upper die base and be used for pouring into the runner of molten metal into the die cavity, the runner includes the sprue and a plurality of branch runners with the sprue intercommunication, be equipped with the flow regulating block in the branch runner, be equipped with the branch discharge orifice in the flow regulating block, the flow regulating block passes through the bolt to be installed in the branch runner, be equipped with in upper die base and the die holder with the cooling water course of die cavity intercommunication.
