It is not that injection, casting mechanism are different.The pressure chamber of hot press chamber die casting machine is closely linked to be an entirety with smelting furnace, and is cold-pressed chamber pressure
The pressure chamber of casting machine is to separate with smelting furnace.
The shot piston of die casting machine injection cylinder is used to connect injection rod to carry out injection effect, and the connection of shot sleeve rear portion increases
Cylinder pressure, pressurized cylinder are used to connect fuel tank, and fuel tank is provided with magnetic valve, and PLC controls the opening and closing of magnetic valve, to control hydraulic pressure
Oil enters back into shot sleeve into pressurized cylinder, and hydraulic oil driving shot piston is stretched.Injection rod front end connects injection plunger, injection
Head is for injection high temperature metal liquid, and injection plunger directly contacts high temperature metal liquid, such as metal aluminium liquid temperature has 700 degree
Left and right, so the temperature of injection plunger can be very high, injection plunger temperature can be conducted to injection rod again, cause injection rod temperature to raise, institute
To need to cool to injection rod.Each hydraulic unit of die casting machine is required for using hydraulic oil, and hydraulic oil is exactly to utilize liquid
The hydraulic medium that the hydraulic system of body pressure energy uses, played in hydraulic system energy transmission, wear-resistant, system lubrication, anti-corrosion,
Antirust, cooling etc. act on.So hydraulic oil can take substantial portion of frictional heat out of, hydraulic fluid temperature is caused to raise, hydraulic pressure
Oil temperature, which reaches 60 DEG C, will make it that hydraulic effect is undesirable, so needing to cool down hydraulic oil.At present to injection rod and
The cooling of hydraulic oil is cooled down each with single recirculated cooling water, and cooling line arrangement is complicated.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of pressure of die casting machine
Penetrate bar hydraulic oil joint cooling structure.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of injection rod hydraulic oil joint cooling structure of die casting machine, including shot sleeve and the injection work for being arranged on shot sleeve
The injection rod of stopper rod front end, injection rod front end connection injection plunger, the injection rod be both ends open hollow tube, an openend
The heat dissipation head for connecting injection plunger is connected with, the radiating block of heat dissipation head is put in hollow tube, and some through holes are provided with radiating block,
Hollow tube side wall is provided with a pair of elongated slots arranged along hollow tube length direction, is provided with elongated slot and is divided into hollow tube cavity
Under two-part dividing plate, cavity connection in top penetrates the water inlet adapter of hollow tube, lower cavity connection penetrating clapboard and hollow tube
Water outlet pipe, water inlet adapter connection is arranged on the delivery port of radiator coil tube in fuel tank, radiator coil tube water inlet connection water source
Place.
Further, the dividing plate both sides have the right angle notch opened up along its length, and rubber spacer is provided with notch.
Further, the one end of the injection rod away from heat dissipation head is sealed with cover plate.
Further, the heat dissipation head setting tool has fin.
Further, the heat dissipation head is made of copper.
The beneficial effects of the utility model are：Cooling water first radiates into radiator coil tube to hydraulic oil, after being heated
Cooling water temperature compared to heat dissipation head temperature it is also very low, so from radiator coil tube come out cooling water again from water inlet adapter enter
Heat dissipation head is radiated in hollow tube, is intake and is circulated from hollow tube upper cavity toward heat dissipation head and flow to bottom from heat dissipation head through hole
Cavity is discharged from water outlet pipe again, is arranged compared to pipeline is saved before.
Brief description of the drawings：
Fig. 1 is the structural representation of the utility model one embodiment；
Fig. 2 is the injection rod schematic side view of the utility model one embodiment；
Fig. 3 is the structural representation of another embodiment of the utility model.
Embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
