Universal Mold Construction Commentary
In the plastic injection molding industry, there are many types of Molds. Generally, we can divide them in 3 big sections.
1.Two Plate Mold
When opening the mold after ejection, we can tell the mold in two parts core side and cavity side easily. The mold has only one parting line, and product parting line located between core side and cavity side. Look at the picture below for more details.
2.Three Plate Mold
When opening the mold after ejection movement, we can see 2 parting lines on the mold. First between top plate and runner stripper plate, second between cavity and core side, it is easy to tell the different with 2 plated mold. Look at the picture below for more details.
General mold construction
We can have a straight look at the picture below, the components of mold are:
1. Top plate (plate 1)
2. Striper plate (plate 2)
3. Runner plate (plate 10)
4. Cavity plate (plate 3)
5. Core plate (plate 4)
6. Spacer Block (plate 6)
7. Bottom plate (plate 9)
8. Ejector plate (plate 7)
9. Ejector retainer plate (plate 8)
For the rapid tooling, the mold structure was simplified by using manual insert and MUD system, it can has shorter turn around.
