A kind of die casting water cooling integral material cylinder
Technical field
The utility model relates to a kind of die casting water cooling integral material cylinder, and the optimization of the material cylinder structure design particularly in microdiecast Design of Dies, belongs to precision die manufacture technology field.
Background technology:
In the design of die casting, the design of material cylinder there are two kinds of schemes usually: one, die casting self has individual sprue bush, then form with the material cylinder on die casting machine the space that stores liquid metals, this material cylinder versatility is good, but there is the error of axiality and dimensional accuracy between the material cylinder on the sprue bush of die casting and die casting machine, to expect between cylinder that two different degrees of wear also directly have influence on the service life of material cylinder simultaneously; Enterprise's monolith cylinder of adopting each mould to have to adapt with it for this reason; During use, because monolith cylinder to run into the high flow rate working environment of high temperature, high pressure and metal usually near die joint end, therefore conventional cooling water extends its service life.
The utility model provides a kind of die casting water cooling integral material cylinder, adopt region use recirculated water cooling material cylinder being produced to localized hyperthermia, reach overall thermally equilibrated effect, thus realize the service life and the guarantee stable production process that extend material cylinder, improve the qualification rate of die life and die casting.
Summary of the invention
A kind of die casting water cooling integral material cylinder is made up of material cylinder, gate end water jacket, pouring slot water jacket, tank four part; Described mould gate end water jacket, tank is in " M " font, and the import and export of material cylinder two ends cooling water are all in the bottom direction of mould; Described pouring slot water jacket, tank is in " bow " font, and the import and export of cooling water are all near end, and the angle that " bow " font tank is accounting for the material cylinder domain is no more than 180 degree; Described gate end water jacket, pouring slot water jacket materials'use 45# Steel material make, and adopt interference fit, assemble by the technique of hot jacket with material cylinder.
A kind of die casting water cooling integral material cylinder is work like this: material cylinder is near the cooling procedure of mould gate end: in press casting procedure, the import and export of material cylinder two ends cooling water are all in the bottom direction of mould, the water inlet pipe water of die joint end enters the second hoop current downflow after flowing in material cylinder and being divided into two strands of semicirculars to join upward to top, entering the 3rd ring, enter Fourth Ring in upper end, under to water outlet behind bottom; The pouring slot place cooling procedure of material cylinder: the import and export of cooling water are all near end, it is the flowing of " bow " font in the tank of current between material cylinder and water jacket, the angle that " bow " font tank is accounting for the material cylinder domain is no more than 180 degree, because water-cooled need for the more severe Lower Half of condition of work.
Use usefulness of the present utility model: owing to have employed gate end water jacket, pouring slot water jacket die casting water cooling integral material cylinder technology, better can solve in production process and expect that cylinder produces the region use water-cooled of localized hyperthermia, reach overall thermally equilibrated effect, thus realize the service life and the guarantee stable production process that extend material cylinder, improve the qualification rate of die life and die casting.

Detailed description of the invention
As shown in Figure 1, 2, a kind of die casting water cooling integral material cylinder is made up of material cylinder 1, gate end water jacket 2, pouring slot water jacket 3, tank 4 four part; Described gate end water jacket 2, tank 4 is in " M " font, and the import and export of material cylinder 1 two ends cooling water are all in the bottom direction of mould; Described pouring slot water jacket 3, tank 4 is in " bow " font, and the import and export of cooling water are all near end, and the angle that " bow " font tank is accounting for material cylinder 1 domain is no more than 180 degree; Described gate end water jacket 2, pouring slot water jacket 3 materials'use 45# Steel material make, and adopt interference fit, assemble by the technique of hot jacket with material cylinder.
