Design method of extrusion die

In order to let more friends know the common knowledge of the mold, the following plastic molds have to talk about the optimization planning of aluminum alloy kneading molds. If you want to know the optimization planning of aluminum alloy kneading molds, you must know the type of kneading mold county. And assembly methods, kneading mold classification, 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 back ends, core heads, etc.) . Depending on the structure of the kneader and the form of the mold base (longitudinal, lateral, and rolling), the mold assembly method is different.

Now let’s take a look at the several ways to classify the kneading mold. The kneading molds can be classified according to the following methods: the first point, according to the cross-sectional shape of the die hole constriction area, can be divided into streamlined molds and double cone molds, etc.,

The second point, the types of products being kneaded can be divided into bar mold , General solid mold, wall plate mold variable section profile and pipe mold, hollow profile mold, etc. The third point, the number of technical die holes can be divided into single 7L die and porous die. Fourth, according to the kneading method and process characteristics, it can be divided into hot kneading molds, kneading molds, reverse kneading molds, successive kneading molds, water-cooled molds, wide spread molds and molds for vertical kneading machines. Cold kneading molds, molds for hydrostatic horizontal kneading machines; fifth point, according to the mold structure, it can be divided into integral molds, discerning molds, removable molds, movable molds, tongue combined molds, flat split combined molds, mosaic molds , And frame mode, front mode and protection mode. Sixthly, according to the shape of the mold, it can be divided into a cone mold with inverted cone, a round-shaped mold with a boss, a silver mold with a regular cone, and a cone-shaped “center cone pressure ring mold with an inverted cone, Circle with inverted cone.
