Which Structure Does The Plastic Mold Consist Of?

- Jul 04, 2019-

Plastic molds are generally composed of mold parts, mold cores, auxiliary parts, auxiliary systems, auxiliary settings, and dead angle processing mechanisms.


1. Mold base: Generally, we don't need our design. We can order directly from the standard mold base manufacturer, which greatly saves the time required to design the mold, so it is called the standard mold base of plastic mold. It forms the most basic part of the plastic mold.


2, mold kernel: mold part is the core part of the plastic mold, it is the most important part of the mold. The molded part of the plastic product is inside the mold core, and most of the time is also processed on the mold core. However, compared to some relatively simple molds, it has no mold part and the product is formed directly on the template. Most of the early plastic molds were so, relatively backward.




3, auxiliary parts: plastic mold commonly used auxiliary parts are positioning ring, nozzle bushing, thimble, grab pin, support column, ejector guide pillar guide sleeve, garbage nails, etc., some of which are standard parts, can Order directly when ordering the formwork, and some need to be designed by yourself.


4. Auxiliary system: The auxiliary system of plastic mold has the following four: pouring system, ejection system, cooling system and exhaust system. Sometimes, because the plastic material used needs to be heated at a high temperature, some heating systems exist in some molds.


5, with the help of settings: plastic mold with the help of the ring hole, KO hole (top stick hole) and so on.


6, dead angle treatment structure: When the plastic product has a dead angle, the mold will have one or more structures to deal with dead angles. Such as sliders, inclined tops, hydraulic cylinders, etc. In most books in China, the mechanism for dealing with dead ends is called the "spinning mechanism".
