Description
Technical field
The utility model belongs to the hot-extrusion mold technical field, is specifically related to a kind of glass of bar disjunctor forging hot extrude mould.
Background technology
The inaccessible mould of the hot extrude of prior art is in the course of the work because of the long quick heating of heated time, mould is under the higher state of temperature for a long time, learn that by the reality test this temperature can be up to 350 ℃-500 ℃, substantially exceed the temperature of hot die steel commonly used, cause intensity and the case hardness of core rod to decline to a great extent, wearing and tearing aggravate and early time discards, therefore make the core rod operating temperature of mould be in suitable and controlled state, guarantee the stability of mould strength and case hardness, prolong die life, reduce the consumption of die change number of times and core rod, enhance productivity, important in inhibiting reduces production costs, prior art also has pair hot-work die to carry out the scheme of cooling provision, is that cavity adds injection but it adopts, and this structure and cooling scheme exist efficient low, the deficiency of the even temperature poor controllability of inhomogeneous cooling, for the hot extrude workpiece of cup shell and rod body disjunctor, heat is concentrated, the easier promotion of core rod temperature, and prior art is difficult to meet the demands.
For example China Patent No. is 96230893.5, name is called the utility model patent of " heat forging die automatic water spray cooling valve ", a kind of automatic water spray cooling valve is disclosed, electromagnet by a relay starting, control the open and close of lift valve by boosting-rod, water spray cooling valve is by with the valve rod of rubber taper working face spool with valve body and the spring of conical valve seat, valve gap forms, water inlet is located at the valve seat lower end in the valve body, the water outlet duct is located on the valve seat conical surface, between valve rod and valve body, valve body and advancing, all be provided with sealing ring between titting water outlet, thereby can guarantee to be full of all the time cooling water in the water inlet pipe and water outlet pipe, and do not produce weeping.This automatic water spray cooling valve focuses on the architecture advances of water spray cooling valve, and fails attention for the mould inside cooling structure, still continues to use the scheme that cavity adds injection.
And for example China Patent No. is ZL200610073936.2, name is called the patent of invention of " lubricated and cooling die in forming technique; the device of forging die and instrument particularly ", a kind of injector head of constituting is disclosed, be used for and cooling die lubricated at forming technique, the device of forging die and instrument particularly, wherein be used for cooling medium, the transfer passage of compressed air and lubricant medium is positioned in the common and compact housing, but they extend with being separated from each other, and wherein disposed respectively nozzle to these flow channels that separate, this nozzle is used for especially the injection of lubricant medium or is used for the injection of cooling medium.This device adopts put-through channel and eject mechanism in order to take into account the function of Cooling and Lubricator, has equally that efficient is low, the deficiency of the even poor controllability of inhomogeneous cooling.
