Accompanying drawing explanation
Fig. 1: cross section structure schematic diagram of the present utility model.
Embodiment
As shown in Figure 1, interior differential adjustable automatic retarding oil cylinder, comprise differential type cylinder barrel 2, interior differential type piston rod 3 and adjustable interior differential lever 1, differential type cylinder barrel 2 has an inner chamber, and its left end is provided with an axial hole coordinated with interior differential type piston rod, and its right-hand member is provided with an axial hole coordinated with adjustable interior differential lever, interior differential type piston rod 3 is placed in differential type cylinder barrel and forms rodless cavity and rod chamber, its left end stretches out, and can move vertically, is provided with shoe cream room in interior differential type piston rod 3, adjustable interior differential lever 1 is positioned in differential type cylinder barrel 2 by adjustable mechanism, axial position is adjustable, its right-hand member stretches out, its left end stretches in the shoe cream room of interior differential type piston rod, differential type cylinder barrel 2 is provided with filler opening A, first oil outlet B and the second oil outlet C, filler opening A is connected with rodless cavity, first oil outlet B is connected with rod chamber, the axial location of adjustable interior differential lever 1 is provided with oil duct, the right-hand member of oil duct is connected with the second oil outlet C by radial direction oil hole, the left end of oil duct is connected with shoe cream room by radial direction oil hole, shoe cream room radial direction oil hole on interior differential type piston rod is connected with rod chamber.Filler opening A is connected to oil feed pump by oil pipe.First oil outlet B and the second oil outlet C is connected to fuel tank by oil pipe.
After pressure oil P enters rodless cavity from filler opening A, promote interpolation dynamic formula piston rod 3 travel forward, now an oil part for rod chamber flows into fuel tank from the first oil outlet B, some oil radial direction oil hole on interior differential type piston rod 3 enters shoe cream room, on adjustable interior differential lever 1, radial direction oil hole D enters oil duct again, finally flows into fuel tank from the radial direction oil hole of oil duct right-hand member through the second oil outlet C; Now interior differential type oil return speed is the fastest, when interior differential type piston rod 3 moves to a certain position, on adjustable interior differential lever 1, radial direction oil hole D is slowly blocked by interior differential type piston rod 3, the recirculating oil quantity of the second oil outlet C slowly reduces, interior differential type piston rod 3 motion speed slowly subtracts gets off until radial direction oil hole D is all blocked, the oil of rod chamber can only flow into fuel tank from the first oil outlet B, is now microinching.Can by regulating the position of adjustable interior differential lever 1, control the time period of slowing down, adjustable interior differential lever 1 more forward, interior differential type piston rod 3 will run to the oil return just starting to block radial direction oil hole D more, deceleration time is more late, in contrary, differential type piston rod 3 slows down more backward, can regulate according to actual needs.
Extrusion process requires that in cavity filling process, need one section of high speed fills type, at this moment wish that the piston motion speed of injection oil cylinder is very fast, but when injection stroke last section stroke wishes again speed to lower, on the one hand, reduce the impact reduction of inertia to mould and the mold use life-span is extended to the injury of mould, on the other hand, if when filling filling velocity or high speed when pattern chamber has soon been filled at a high speed, liquid aluminium liquid can spray from the mold joint of two moulds, at this moment the liquid aluminium liquid of high temperature spills and can hurt people, be exactly the quality of product that workpiece can produce that burr (overlap) affect workpiece in addition, general injection oil cylinder cannot accomplish deceleration, realize deceleration now much design be at the return opening of oil cylinder, electric proportional valve control system or servo-control system are installed to realize the control of return opening flow to realize deceleration, the relatively above-mentioned two kinds of modes of differential adjustable automatic retarding oil cylinder in the utility model, there is structure simple, easy for installation, cost is low, easy to adjust, the advantages such as low are required to the turbidity test of hydraulic oil.
It is to be understood that: the above is only preferred implementation of the present utility model; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
