In order to let more friends know the common knowledge of molds, the following plastic molds need to talk about the optimization planning of aluminum alloy kneading molds. To know the optimization planning of aluminum alloy kneading molds, you must know the type of kneading mold county. And assembly methods, classification of kneading molds, etc., mold components generally include molds, mold pads and mold supports or mold holders to fix them (when kneading hollow products, mold components also include needle tips, needle rear ends, core heads, etc.) . Depending on the structure of the kneader and the form of the mold base (vertical motion, traverse motion, rolling type, etc.), the mold assembly method is different.
 
Now let's take a look at several ways to classify the kneading molds. Kneading molds can be classified according to the following methods: First, according to the shape of the cross-sectional area of ​​the compacted area of ​​the mold hole, it can be divided into streamlined molds and double cone molds. Second, the types of products being kneaded can be divided into bar molds. , General solid mold, wall panel mold section profile and pipe mold, hollow profile mold, etc. Third, the number of holes in the technical mold can be divided into a single 7L mold and a porous mold. Fourth, according to the kneading method and process characteristics, it can be divided into hot kneading molds, kneading molds, back kneading molds, successive kneading molds, water cooling molds, wide molds and molds for vertical kneading machines. Cold kneading mold, mold for hydrostatic horizontal kneader; Fifth, according to the mold structure, it can be divided into overall mold, discrimination mold, removable mold, movable mold, tongue-type combination mold, plane split combination mold, mosaic mold , And frame mold, front mold and protective mold. Sixth point, according to the mold structure, it can be divided into a cone mold with an inverted cone, a round mold with a boss, a silver mold with a positive cone, a cone "central cone pressure ring mold with an inverted cone, Circle with inverted cone.
