Plastic injection mould in molding the parts can be divided into the mouth, mandrel, filter, filter plate, shunt, and so on.
The following works of plastic products factory in changshu, in turn, to say the five kinds of plastic injection mould parts.
the first kind is the mouth of the plastic extrusion die mold design, and to a certain extent affect the melt extrusion machining stability and precision, by the physical principle of rheology, coupled with the experience in design and trial die correct finish off the process such as the die design.
the second is plastic extrusion die mandrel, role in molding mould products of inner hole, the hole forming, because will teach under compressive stress and bending stress, plastic extrusion die mandrel needs with machine guns compressive strength, hardness and wear resistance.
the third kind is the filter on the plastic injection mould, the commonly used material for stainless steel metal mesh, plastic seal is formed between extrusion mould machine and forming mould, filter blocking will interfere with the plastic material melt temperature, temperature drop after molding, can make the mold size change.
fourth one is the filter plate, plastic extrusion die is used to filter tiny suspended particles, need to use the bibulous rate is small, the corrosion resistance of polyethylene materials are difficult to stick to make the filter plate, can very good instead of the ceramic filter medium alkali resistance is not strong, and many other problems.
the fifth kind is plastic extrusion die shunt, can let the movement rule of plastic melt changes, by spiral change into linear motion, also can let the extrusion of plastic melt in the compression is more compact, makes plastic extrusion die material layer is thinner and more uniform plasticizing, enhance the strength of the finished product.
