The content of the invention
The purpose of the utility model is to overcome the deficiencies in the prior art, it is proposed that a kind of combination of fan blade shaping
Formula mould pumping group, can effectively avoid resin and enters exhaust pipe, avoid resin from blocking bleeding point, and fast and easy changes, together
When also reduce replacement cost.
To achieve the above object, technical solution provided by the utility model is：A kind of combination of fan blade shaping
Formula mould pumping group, includes at least two mould pumping cells being connected in series, each mould pumping cells are by detachable
The upper and lower exhaust tube composition of connection, wherein, the top of the upper exhaust tube is formed with rib, the mould of fan blade shaping
Shape size and the counterbore that should be matched with the upper exhaust tube top of rib, the upper pumping with rib are provided with flange
Pipe top is placed in the counterbore, and the lower part of the upper exhaust tube through assembling top nut after the counterbore and is tightened, and passes through the spiral shell
Female rib with upper exhaust tube top is engaged clamping so that upper exhaust tube is fixed on mould flange, the upper exhaust tube
Lower part and the top of lower pumping pipe are connected through a screw thread, and the lower part of the lower pumping pipe is inside and outside nested type double pipe structure, this is interior
The outer tube top seal of outer nested type double pipe structure, bottom opening, inner tube is connected with upper exhaust tube, and extends downwardly outer tube, institute
The bottom for stating outer tube is detachably connected the container for being useful for collecting resin, and the both sides of the outer tube are connected with the pumping being connected and connect
Connector, is cascaded between mould pumping cells by respective pumping connector two-by-two, and two moulds of head and the tail are taken out
The external vacuum pump pumping of corresponding pumping connector of gas unit.
The container is the internal diameter see-through section consistent with outer pipe outside diameter, the bottom lock of the see-through section.
The utility model compared with prior art, has the following advantages that and beneficial effect：
1st, this sectional die pumping group firmly installs, good airproof performance, can increase or decrease mould pumping according to the actual requirements
Gas unit number.
2nd, effectively avoid resin from entering exhaust pipe, avoid resin from blocking bleeding point.
3rd, fast and easy changes, regular dismounting lower pumping pipe, removes bleeding point resin using burning, resin trap container can
Dismounting and change, when placing outdoor preservation, can directly dismantle lower pumping pipe, avoid corrosion.
Brief description of the drawings
Fig. 1 is the scheme of installation of sectional die pumping group.
Fig. 2 is the stereogram of mould pumping.
Embodiment
With reference to specific embodiment, the utility model is described in further detail.
Referring to the sectional die pumping group for the fan blade shaping that shown in Fig. 1 and Fig. 2, the present embodiment is provided, bag
At least two mould pumping cells 1 being connected in series are included, each mould pumping cells 1 are by the upper and lower pumping being detachably connected
Tracheae 11,12 forms, wherein, the top of the upper exhaust tube 11 is formed with rib 111, while the mould of fan blade shaping
Shape size and the counterbore that should be matched with the upper exhaust tube top 11 of rib 111 are provided with flange 2, it is described to carry rib
111 upper exhaust tube top 11 is placed in the counterbore, and the lower part of the upper exhaust tube 11 passes through fit on spiral shell after the counterbore
Mother 112 simultaneously tightens, and clamping is engaged with the rib 111 on upper exhaust tube top 11 by the nut 112 so that upper exhaust tube 11 is solid
Due on mould flange 2, the lower part of the upper exhaust tube 11 is connected (specifically with the top of lower pumping pipe 12 by internal and external threads
Upper exhaust tube 11 is equipped with external screw thread, and lower pumping pipe 12 is equipped with internal thread), the lower part of the lower pumping pipe 12 is inside and outside nesting
Formula double pipe structure, 121 top seal of outer tube of the inside and outside nested type double pipe structure, bottom opening, inner tube 122 and upper exhaust tube 11
Connection, and 121 certain length of outer tube (being usually 10mm) is extended downwardly, the bottom of the outer tube 121, which is detachably connected, to be useful for
The container 13 of resin is collected, in the present embodiment, the container 13 is specially the internal diameter transparent pipe consistent with 121 outside diameter of outer tube
Section, the bottom lock of the see-through section, the both sides of the outer tube 121 are connected with the pumping connector 123 being connected, two-by-two mould
It is cascaded between pumping cells 1 by respective pumping 123 connecting pipe of connector, and two mould pumpings of head and the tail
The corresponding pumping connector 123 of unit 1 is evacuated by the external vacuum pump of pipeline (being not drawn into figure).
The present embodiment combinations of the above formula mould pumping group installs mould by the way of being installed again after punching after the completion of punching
Have pumping cells, silica gel is applied on counterbore, then put upper exhaust tube into hole position, tighten nut, flat pattern face is scraped with structure glue, Gu
Change polishing, polishing are completed, with there is hole isolation film to seal bleeding point, to wind above at the external screw thread of exhaust tube using raw material band, lower pumping
Pipe is tightened, and is just completed the installation of mould pumping cells, is similarly sequentially completed the installation of each mould pumping cells again, finally by
The each mould pumping cells of placed in series, you can complete the installation of whole sectional die pumping group.
