In prior art, Chinese patent CN201730898U discloses a kind of oil cylinder carrying cooling unit, described oil cylinder is fixed on one piece of cooling plate, cooling plate forms return flow line, return flow line is provided with water inlet tap and water outlet, and oil cylinder is lowered the temperature by cooling plate, and this cooling unit is arranged on the outside of oil cylinder, cooling-down effect is very limited, do not reach the object to oil cylinder effective temperature-reducing, therefore, be necessary to be improved.
Summary of the invention:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of cooling oil cylinder, and have good cooling effect, long service life, cost is low, the simple advantage of structure.
Technology solution of the present utility model is as follows: a kind of cooling oil cylinder, comprise the cylinder body be fixedly installed on high temperature template, described cylinder interior is provided with piston, the central authorities of described piston end surface are fixedly connected with piston rod, one end face of described cylinder body is fixedly installed end cap, one end of piston rod extends to end cap outside, between described piston rod and piston, Sealing is provided with between piston and cylinder body and between piston rod and end cap, described piston rod is provided with deep hole near one end of end cap, intake pipe is provided with in described deep hole, described intake pipe one end to be inserted in described deep hole and to keep certain spacing with the bottom end of deep hole, the other end extends to the outside of piston rod by flange, it is also provided with outlet pipe to the end face that described flange is fixedly installed on piston rod, be connected on flange outside described outlet pipe.
Preferred as technique scheme, the spacing of the water outlet of described intake pipe and the bottom end of deep hole is 20mm.
Preferred as technique scheme, described deep hole is arranged on the non-operative end of piston rod, and the working end of described piston rod acts on the ejector plate of mould.
Preferred as technique scheme, described flange is threaded with between piston rod.
Preferred as technique scheme, described Sealing is oil sealing and seal ring.
Preferred as technique scheme, described cylinder body is bolted and is arranged on high temperature template.
The beneficial effects of the utility model are: by arranging a deep hole in the non-operative end of piston rod, in described deep hole, an intake pipe is installed, the feed-water end flange of water pipe arranges an outlet pipe simultaneously, a circulating water cooling system can be formed like this at the piston rod inner of oil cylinder, ensure that the Sealing around piston rod is in low temperature environment all the time, thus ensure that the sealing of oil cylinder is not easy to produce oil leakage phenomenon, if re-use inlet seal part in this kind of situation, then both greatly can strengthen the working life of oil cylinder, reduce its user cost.
