The utility model is simple in structure, easy to use.Forcing press when work, move under the effect that ejects cylinder of supporting plate under it, during the slide block backhaul, many push rods move in jogger hole corresponding to mould bottom, eject manufactured goods or the crude product of shaping, only have guiding mechanism of the present utility model to work this moment, and remainder is not worked.When needing to take out push rod, hydraulic oil enters in the plunger case from the plunger turnover oilhole road of liftout tank, move on the plunger case, until the buffer stopper on its top touches till the working plate downside of travelling table, liftout tank drives supporting plate so that move on the push rod and stretch out travelling table, can take out very easily or change push rod, reduce workman's labour intensity, improve operating efficiency.The utility model is arranged in the moveable platform of press, not be used in melt pit to be set in the sending area of travelling table cylinder or oil cylinder are installed good looking appearance and protected liftout tank to avoid its accident impaired.
Advantage and disadvantage of the present utility model will be for illustration and explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is structural representation of the present utility model, and push rod stretches out from the working plate upside among the figure;
Fig. 2 is the A-A cutaway view of Fig. 1, and push rod is removed among the figure.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises travelling table 1, travelling table 1 two ends are provided with the vehicle frame 11 that travelling table can be shifted out the forcing press body, be provided with respectively liftout tank 2,3 one-tenth rectangular arrangements of many push rods on 1 four jiaos of downsides of moveable platform of press, push rod 3 upper ends can pass travelling table platen 12, supporting plate 4 is positioned at the travelling table inboard and is arranged on many push rods 3 lower ends, polylith backing plate 5 is separately fixed on the supporting plate 4, backing plate 5 positions are corresponding with push rod 3 lower ends, and push rod 3 lower ends are bearing on the supporting plate 4 by backing plate 5.
Liftout tank 2 is plunger case, be positioned at travelling table platen 12 downsides, comprise plunger 21, plunger case 22 and sealing ring 23, plunger 21 lower ends are fixed on the lower plate 111 that is welded on vehicle frame 11 lower ends by several securing members, plunger case flange 221 ports are sleeved on downwards on the plunger 21, plunger case terminal port flange 221 is fixed on supporting plate 4 downsides, be connected by sealing ring 23 slipper seals between plunger case 22 and the plunger 21, the sealing ring 23 of the present embodiment adopts Yx type hole sealing ring, long working life, good sealing effect.Buffer stopper 24 is fixed on plunger case 22 tops, and the buffer stopper 24 of the present embodiment adopts rubber to make, and has avoided rising on plunger case 22 tops bump travelling table platen 12 downsides, thereby has effectively protected liftout tank 2, plays good cushioning effect.Turnover oilhole road 211 extends upward from plunger 21 lower ends and passes plunger 21 upper end end faces, does not need to arrange specially in addition the turnover oil pipe, simplifies the structure, and has improved the reliability of liftout tank 2 work.
