Description
Technical field
The utility model relates to a kind of large-scale blow molding machine, particularly relates to a kind of large-scale blow molding machine folding mould oil cylinder structure.
Background technique
The clasp mould mechanism of large-scale blow molding machine requires that oil cylinder stroke is large, and will have very large locked mode pressure to ensure the shaping of blow-molded article after mould matched moulds puts in place, requires high in folding mould hourly velocity, and the oily flow of needs wants large, and pressure is low; Require during locked mode that oily flow is little, pressure is high.The closing mould mechanism of current domestic and international large-scale System of Hollow Blow Shaping Machine generally adopts two or three independent oil cylinders to work in coordination with low pressure and mass flow rapid mould opening-closing and high-pressure low-flow locked mode function at a slow speed, an oil cylinder performs rapid mould opening-closing, another or two oil cylinders perform locked mode at a slow speed, not only hydraulic system pipeline is complicated, and need system to provide high-pressure high-flow to meet folding mould and locked mode requirement, thus very powerful motor is needed to drive, observable index is larger, cost of production is high, the call that national energy-saving reduces discharging can not be responded, also have very large a part of merit to change into heat energy simultaneously, oil temperature is caused to raise, reduce the working life of oil cylinder.
Model utility content
Technical problem to be solved in the utility model is: the large-scale blow molding machine folding mould oil cylinder structure providing a kind of good energy-conserving effect.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: large-scale blow molding machine folding mould oil cylinder structure, comprise: oil cylinder body, piston rod is fastened in the oil cylinder body that cooperatively interacts with it by FERRULETYPE flange, oil cylinder ante-chamber and oil cylinder back cavity is provided with between described oil cylinder body and piston rod, piston oil pocket is provided with in described piston rod, the connecting tube described oil cylinder body being provided with the filler opening be connected with oil cylinder ante-chamber and being connected with oil cylinder back cavity, fuel reserve tank is connected with by connecting tube above described oil cylinder body, the oil cylinder passage be connected with piston oil pocket is provided with at the middle part of described oil cylinder body, described oil cylinder passage is connected with the return opening be arranged on oil cylinder body.
The utility model has the advantages that: above-mentioned large-scale blow molding machine folding mould oil cylinder structure; by the fuel reserve tank be arranged on above oil cylinder, idle switching is carried out to in-oil cylinder hydraulic oil; hydraulic system is only needed to provide the hydraulic oil of small flow high pressure power just can meet the normal work of large-scale blow molding machine clasp mould mechanism; energy consumption is little; reduce cost of production; reach energy-conservation object, in-oil cylinder hydraulic oil in use can not heat up simultaneously, extends the working life of oil cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model large-scale blow molding machine folding mould oil cylinder structure.
Structural representation when Fig. 2 is the utility model large-scale blow molding machine folding mould oil cylinder structure locked mode.
In figure: 1, oil cylinder body, 2, piston rod, 3, FERRULETYPE flange, 4, oil cylinder ante-chamber, 5, oil cylinder back cavity, 6, piston oil pocket, 7, filler opening, 8, connecting tube, 9, fuel reserve tank, 10, oil cylinder passage, 11, return opening.
Embodiment
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, shown in Fig. 2, large-scale blow molding machine folding mould oil cylinder structure, comprise: oil cylinder body 1, piston rod 2 is fastened in the oil cylinder body 1 that cooperatively interacts with it by FERRULETYPE flange 3, oil cylinder ante-chamber 4 and oil cylinder back cavity 5 is provided with between described oil cylinder body 1 and piston rod 2, piston oil pocket 6 is provided with in described piston rod 2, the connecting tube 8 described oil cylinder body 1 being provided with the filler opening 7 be connected with oil cylinder ante-chamber 4 and being connected with oil cylinder back cavity 5, fuel reserve tank 9 is connected with by connecting tube 8 above described oil cylinder body 1, the oil cylinder path 10 be connected with piston oil pocket 6 is provided with at the middle part of described oil cylinder body 1, described oil cylinder path 10 is connected with the return opening 11 be arranged on oil cylinder body 1.
As shown in Figure 1, when above-mentioned large-scale blow molding machine folding mould oil cylinder structure uses, when filler opening 7 oil-feed, return opening 11 oil return, the oil in oil cylinder back cavity 5 gets back to liquid tank 9 by connecting tube 8, and piston rod 2 is moved to the left, now oil pump small flow, little forced feed, energy consumption is little.
As Fig. 2, when return opening 11 oil-feed, filler opening 7 oil return, the oil in liquid tank 9 is got back in oil cylinder back cavity 5 by connecting tube 8, and piston rod 2 moves right, now oil pump small flow, and little forced feed, energy consumption is little.When locked mode, oil cylinder back cavity 5 is full of by idle oil, return opening 11 and filler opening 7 oil-feed, only needs very little flow and high pressure, thus realizes energy-conservation object.
