The technical solution that the utility model solves the problems, such as is：A kind of universal Bending Mould coordinates including lower die, with lower die
Upper mold, the upper mold include core bar, R angle moulds, the core bar lower end is detachably connected with R angle moulds；
The R angle moulds be equipped with it is multiple, be respectively provided with the R angles of different size model numbers.
The form of several components assembling will be molded as in said program in a traditional entirety so that R angle moulds can be with
It is convenient to replace, can be with dismounting and change R angles when carrying out different R angles bendings, and do not have to replace core bar, increase versatility.
Further, open first cavity in top is equipped on R angle moulds, the first screw hole is equipped at the top of R angle moulds；
The fastener with being docked at the top of R angle moulds is further included, which includes the snap-gauge of a pair of of inverted L-shaped, two pieces of snap-gauge mirrors
As being symmetrical arranged into the portal structures of the second cavity with bottom-open, on each piece of snap-gauge with the first screw hole corresponding position
Equipped with the second screw hole；
Both sides are docked with snap-gauge at the top of R angle moulds, and the first cavity and the second cavity surround to form the chamber that top carries via；
The core bar lower end is equipped with connecting portion, which is set in chamber without deviating from, and connecting portion and chamber
Shape and size are identical, and core bar is pierced by from the top via of chamber；
Fastener is fixedly connected by screw also cross the second screw hole and the first screw hole with R angle moulds.
The effect of fastener is to fix core bar and R angle mould relative positions so that R angle moulds can link with core bar.
Further, the outer contour shape of the connecting portion is identical with the outer contour shape of R angle moulds, the outer profile of connecting portion
Size of the size for R angle mould outer profiles after scaled.
Connecting portion is designed to the shape identical with R angle mould outer profiles so that connecting portion also becomes a R angle in itself
Mould, its own can also be used separately as the upper mold of a certain specific size.
For the ease of bending, having heaters is all provided in the core bar and lower die.
The remarkable result of the utility model is：
1. by the form of several component assemblings is molded as in a traditional entirety so that R angle moulds can easily more
It changes, can be with dismounting and change R angles when carrying out different R angles bendings, and do not have to replace core bar.Replace it is convenient and efficient, efficient,
Versatility is increased, while also saves upper mold cost of manufacture.
2. due to being changed without core bar, then heater does not need to replace variation therewith, and manufacturing process is simple, and cost is also lower.
