Embodiments of the present invention working procedure is as follows: before starting working, and is placed on by mould on hotpress, adds raw material, hotpress startup work.Motor 1 starts, and oil pump 2 is started working.
Left position got by first selector valve 43, left position got by the 6th selector valve 4221.Liftout tank 35 starts, and ejects piston rod and moves downward, and prevents from ejecting piston rod and blocks mould and enter hotpress.
Left position got by first selector valve 43, left position got by the 5th selector valve 4212.Release cylinder 34 to start, pushing piston-rod advances fast, mould is drawn in hotpress inside.When mould is near precalculated position, meta got back to by one of them the 5th selector valve, and pushing piston-rod slows down, and is slowly drawn in by mould.
Right position got by first selector valve 43, right position got by the 3rd selector valve 4131.Fine setting cylinder 32 starts, and fine setting piston rod upwardly, adjusts the bolster keeping parallelism of mould.
Helper motor 5 and auxiliary oil pump 6 are opened, right position got by the first selector valve 43, right position got by the second selector valve 4121.Master cylinder 31 starts, main piston rod upwardly mould fast.And then right position got by the 3rd selector valve 4131, and fine setting cylinder works on, process mould bolster parallel of the motion that keeps up.
Start master cylinder venting: right position got by the first selector valve 43, right position got by the 3rd selector valve 4131, right position got by the second selector valve 4121, main cylinder piston-rod declines, and in fine setting cylinder maintenance decline process, mould bolster is parallel.Pause a little while, treat that gas is discharged.Helper motor 5 and auxiliary oil pump 6 are opened, right position got by the first selector valve 43, right position got by the second selector valve 4121, right position got by the 3rd selector valve 4131, and main cylinder piston-rod rises tight for mould conjunction.Circulation like this arrives the exhaust number of times of setting.
Helper motor 5 and auxiliary oil pump 6 are opened, right position got by the first selector valve 43, right position got by the second selector valve 4121, right position got by the 3rd selector valve 4131, and master cylinder 31 boosts to the sulfide stress of setting, when starting curameter.
Cure time arrives, and right position got by the first selector valve 43, right position got by the 3rd selector valve 4131, and left position got by the second selector valve 4121.Master cylinder bypass is switched to out oil condition, and because the pressure outside master cylinder 31 is greater than the pressure of master cylinder 31 internal liquid, master cylinder 31 only may not make mould bolster separately by the effect of gravity, and rate of descent is very slow.Right position got by first selector valve 43, left position got by the 4th selector valve 4141, left position got by second selector valve 4121, die sinking plunger upwards ejects, an active force is upwards applied to the fixed cross beam of on hotpress, the downward driven mold of reaction force help master cylinder plunger piston that crossbeam split cavity cylinder is downward, finally drops to bottom.
Right position got by first selector valve 43, right position got by the 5th selector valve 4212, and release cylinder 34 and start, mould is released outward toward hotpress by thruster piston rod fast.Time soon close to precalculated position, wherein one article of the 5th selector valve 4212 releasing cylinder shunt 4211 recovers meta, and mould is pushed into precalculated position at a slow speed by thruster piston rod.
Right position got by first selector valve 43, right position got by the 6th selector valve, and liftout tank 35 starts.Eject piston rod upwards product to be ejected.
Although describe embodiments of the present invention by reference to the accompanying drawings, those of ordinary skill in the art can make various distortion or amendment within the scope of the appended claims.
