Description
Technical field
Injection mold field is the utility model is related to, more particularly to a kind of charging runner improved mould.
Background technology
Mould be in industrial production being molded, being blow molded, extruding, die casting or obtain the methods of forging forming, smelting, punching press
The various moulds and instrument of required product.
With reference to figure 6, mould typically includes die holder plate 1, stripper plate 2, solid plate 3, moving platen 4 successively, in die holder plate 1, takes off
Sprue bush 9 is provided with flitch 2, the feed channel 13 connected with sprue bush 9 is provided with the upper surface of solid plate 3, material is most laggard
Enter and formed into the mold cavity 12 on moving platen 4.
When needing feeding, because the rod-like element connected between moving platen and solid plate by interference is relatively fixed, thus
When pulling moving platen and solid plate, the material on the feed channel on solid plate is first separated with product；It is then dynamic when pulling again
During template, due to removing product on solid plate and stripper plate, while the waste material on the sprue puller set on stripper plate is removed.
It is used to that after directly penetrating solid plate sprue bush will be connected, it is necessary to open up extra feed channel as seen from the figure and determines
Mold cavity connection on die, thus when mold cavity quantity is more, the number of paths of the feed channel on solid plate increases, and enters
Material road increasing number causes waste material caused by feed channel of the material on solid plate equally to increase, and causes many unnecessary waves
Take.
Utility model content
The purpose of this utility model is to provide a kind of charging runner improved mould, has and reduces on solid plate Shang Liao roads
