Description
Technical field
The utility model relates to die casting technical field, in particular to a kind of local extrusion device for mold.
Background technique
Die casting be by liquid or semi-liquid metal, high pressure effect under, be at a high speed filled into the type chamber of compression mod, and
A kind of method of casting is quickly solidified and obtained under stress.In press casting procedure, general wall thickness is in liquid metal solidification mistake
Cheng Zhonghui generates hole in inside because of shrinking, and we term it shrinkage cavities for these holes.Shrinkage cavity can be to the mechanical performance of product
It has an impact, reduces the performance of part, or even scrap casting.When two that need locally to be squeezed on casting local spacing
When closer, two individual extrusion oil cylinders can not be installed simultaneously to carry out local extruding.
Utility model content

In pressing sleeve cylinder, double piston-rod driving cylinder is installed on die holder, and there are two piston rod, each piston rods for double piston-rod driving cylinder tool
It is sequentially connected with each squeeze pin.
Further, each squeezes sleeve and uses staged sleeve, and one section of close die cavity is interior on staged sleeve
Internal diameter of the diameter compared with another section is small, and squeeze pin uses stepped shaft compatible with staged sleeve diameter.
Further, the double piston-rod driving cylinder is using hydraulic cylinder or cylinder or motor.
Further, the die holder is equipped with mounting groove, and the two sides of double piston-rod driving cylinder are connected with fixed block, fixed block
It is equipped with perforation, screw rod is arranged in perforation, and one end of screw rod is connected with sliding block, and the other end is bolted with nut, and sliding block is slidably
Ground is set in mounting groove, tightening nuts, and double piston-rod driving cylinder can be fixed on to the predetermined position in mounting groove.
The utility model is used for the local extrusion device of mold, by installing double piston-rod driving cylinder, dual-active in module
Two piston rods of stopper rod driving cylinder are sequentially connected with two squeeze pins respectively, since two piston rods are installed on same cylinder body
On, compact-sized, convenient for interior installation in a limited space, and the spacing of two piston rods is smaller, is able to achieve constant speed reciprocating in the same direction
Movement enables squeeze pin two extrusion positions closer to spacing to carry out local extruding, improves product quality.
Detailed description of the invention
Fig. 1 is broken section structural schematic diagram of the utility model for the local extrusion device of mold.
Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear
