Ring-type die cavity, is then shut off control valve, and charging cylinder drives casing drum return, and then compacting cylinder drives upper mold to move down, upper mold
Stretch between die sleeve and core rod and match with lower mold thus the PTFE raw material in circular die cavity is suppressed, then upper mold
Upper shifting, is fed again by casing drum, is suppressed again by upper mold, thus forms the cylindric PTFE seal pad of proper height
Blank, then ejects cylinder band moving-mould-core and die sleeve moves down simultaneously, then lower mold rises relative to core rod and die sleeve thus drives circle
Tubular PTFE seal pad blank stretches out outside circular die cavity, and then charging cylinder drives casing drum in lower mold, casing drum
Scraping wings moves thus pushes away at lower mold by cylindrical shape PTFE seal pad blank, then ejects cylinder band moving-mould-core and die sleeve
On retract position, casing drum can carry out the charging of next product, when scraping wings releases cylindric PTFE seal pad blank, bullet
Property block piece gear in the front side of cylindric PTFE seal pad blank, prevent cylindric PTFE seal pad blank from falling, receiver can be deposited
Put multiple cylindric PTFE seal pad blank.
The beneficial effects of the utility model are: using said structure, the automatization that can realize PTFE seal pad blank adds
Work, easy to operate, production efficiency is high, it is not necessary to cuts off, also will not collide, good product quality.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, a kind of PTFE seal pad blank compression molding device, including frame, described frame is provided with fixing seat
1, this fixing seat is vertically fixed with the lower mold 2 of hollow, be provided with in this lower mold can the core rod 3 of the upper and lower slip of the most described lower mold,
Be set with outside described lower mold can the die sleeve 4 of the upper and lower slip of the most described lower mold, the upper end phase of the upper end of this die sleeve and described core rod
Flushing, described core rod and die sleeve drive by ejecting cylinder 5 simultaneously, and described die sleeve extenal fixation has sliding seat 6, the upper end of this sliding seat
Flushing with the upper end of described die sleeve, the surface of described lower mold is provided with the upper mold 7 of hollow, and this upper mold is driven by suppressing cylinder 8
Thus move up and down, when described upper mold moves down, the lower end of described upper mold is stretched between described die sleeve and core rod, and described on
The inwall of mould 7 contacts with the outer wall of described core rod 3, and the outer wall of described upper mold contacts with the inwall of described die sleeve, described work
Dynamic seat 6 is provided with and is driven thus the casing drum 10 of forward and backward movement by charging cylinder 9, and this casing drum passes through charge pipe and mixer
Being connected, this casing drum is provided with charge pump, and the lower end of this casing drum is provided with charge door, adds described in when described casing drum moves forward
Material mouth is relative with described lower mold, and described charge door is provided with control valve, and being arranged over described casing drum of described sliding seat 6 is same
Moved further is also positioned at the scraping wings 11 of back upper place of described lower mold, and described scraping wings is circular arc, PTFE seal of preferably fitting
Pad blank.
Described sliding seat 6 be arranged over being positioned at the elastic block piece 12 of the front upper place of described lower mold, elastic block piece can select
Use steel wire.
The front of described sliding seat 6 is provided with receiver 13, is used for holding PTFE seal pad blank.
Vertically it is provided with lead 14 on described fixing seat 1, connects by being connected seat 15 between described compacting cylinder and upper mold,
