Environmental technology:  

Most of the traditional magnets are made according to the way of calcination forming or bonding forming. Although they have high magnetic properties, they are not easy to form high-precision products with complex structures.  With the development of plastic granulation technology and the tendency of mold magnetization technology more and more magnets are made by injection molding process.  Compared with the calcination method, the production of magnets by injection molding process has the advantages of high precision product specifications, good impact toughness, complex product appearance and easy multi-pole trend, and high production and manufacturing efficiency. In recent years, suppliers of plastic magnetic particles have gained a rapid development trend.  

Although the processing technology of injection molding has many advantages in making magnets, it is unknown that the shrinkage of the diameter of the product after the molding of the traditional cooling mold is inconsistent along the radial direction, that is, the poor symmetry of the diameter of the product in the radial direction endangers the practical effect.  

In view of this, the invention provides a new injection processing magnet cooling mold, the supplier of plastic magnetic mold to get rid of the above technical deficiencies.  

Technical completion factors:  

The utility model has the effect of giving a magnet cooling mold for injection molding, so as to obtain a product with good diameter and radial symmetry, which solves the above technical shortcomings.  

In order to accomplish the above purposes, one of the technical specifications of the utility model is as follows:  The cooling mold, injection molding processing magnet it contains cavities, professional plastic magnetic ferrite installation in the cavities in the core and the cavities and the core arranged in the inner chamber products, the mould kernel multiple unrelated circular cooling channel is set up, each of the above the cooling channels around the product inside the cavity field along the inner cavity uniform radial distribution,  Each cooling passage is provided with an inlet and an outlet.  

The cooling channel comprises a first cooling channel, a second cooling channel, a third cooling channel and a fourth cooling channel successively distributed in the mould from top to bottom.
