Abstract
The invention discloses the device and process that a kind of new vacuum imports shaping big height difference product, gum-injecting port is arranged to the bottom of product, while injecting glue barrel is promoted to and product peak sustained height.The vacuum bagging skin of product minimum point places the height that a pressure inductor is used to control injecting glue barrel, if the registration of pressure inductor is more than 1000mbar, injecting glue barrel is then automatically controlled to decline to maintain inductor registration constant, the position of gum outlet and quantity, the position of gum outlet is set to be arranged at the peak of product according to the size of product.The present invention solves the problems, such as that the internal soundness that vacuum is imported caused by shaping big height difference product is non-uniform, solves the problems, such as, with height increase resin flow fronts injection pressure decay is imported, to have evaded product peak surface dry spot risk.
Description
Technical field
The present invention relates to the device and process that a kind of vacuum imports shaping big height difference product.
Background technology
Vacuum introducing technology（Vacuum infusion process), abbreviation VIP, in mould upper berth " dry " reinforcing material
（Glass fibre, carbon fiber, Sandwich materials etc.）, vacuum bag, and the vacuum in extraction system are then spread, is formed in mold cavity
One negative pressure, is pressed into resin in fibrous layer by the pipeline that overlays using the pressure that vacuum produces, and allows resin infiltration strengthening material
Material finally obtains required product full of whole mould.
Vacuum introducing technology is a kind of inexpensive composite liquid moulding process.Compared to traditional autoclave technique
For, vacuum introducing technology can be molded large-sized composite product from the limitation of autoclave size.Existing vacuum
Introducing technology is arranged at the least significant end of product when being molded big height difference product more gum-injecting port and injecting glue barrel, as resin is injected
Height increases, and the injection pressure of resin flow fronts will produce decay, and the decay of the highest point resin of product is the most serious.
Remaining injection pressure after decay moves on it could even be possible to being not enough to promotion resin, so may result in the interior of whole product
Portion's quality is very uneven, and dry spot risk occurs in the highest point that serious situation results even in product.
The content of the invention
Caused internal soundness problem of non-uniform, Yi Jisui during in order to solve vacuum importing shaping big height difference product
The problems such as importing height increases the decay of resin flow fronts injection pressure, and product peak surface easily produces dry spot.This hair
A kind of bright device and process for providing new vacuum and importing shaping big height difference product.
A kind of new vacuum imports shaping big height difference product device, including product, and product bottom sets gum-injecting port, note
Jiao Kou set injected rubber hose, injected rubber hose connection glue injection barrel, injecting glue barrel be located at on product peak sustained height, product is minimum
The vacuum bagging skin of point places a pressure inductor, for controlling the height of injecting glue barrel, if the registration of pressure inductor surpasses
1000mbar is crossed, then height controller automatically controls injecting glue barrel and declines to maintain inductor registration constant, finally, according to system
The size of part sets the position of gum-injecting port and quantity, the position of gum outlet to be arranged at the peak of product, and gum outlet connects out
Sebific duct, goes out the height of the sebific duct peak between and flushes.
A kind of new vacuum imports the technique of shaping big height difference product, and gum-injecting port is arranged to the bottom of product, note
Jiao Kou set injected rubber hose, injected rubber hose connection glue injection barrel, by injecting glue barrel be promoted to product peak sustained height, then,
The vacuum bagging skin of product minimum point places the height that a pressure inductor is used to control injecting glue barrel, if pressure inductor
Registration automatically controls injecting glue barrel and declines to maintain inductor registration constant more than 1000mbar, then height controller, finally,
The position of gum-injecting port and quantity, the position of gum outlet is set to be arranged at the peak of product according to the size of product, gum outlet
Sebific duct is connected out, goes out the height of the sebific duct peak between and flushes.
The present invention solves the problems, such as that the internal soundness that vacuum is imported caused by shaping big height difference product is non-uniform, solves
The problem of with height increase resin flow fronts injection pressure decay is imported, product peak surface dry spot wind is evaded
Danger.Meanwhile import glue filling device the present invention provides a kind of new vacuum, the device can with pressure inductor change from
It is dynamic to adjust injection height.

Embodiment
The present invention, but the not scope of limitation the claims in the present invention protection are further illustrated with reference to embodiment.
As shown in Figure 1, 2, a kind of new vacuum imports shaping big height difference product device, including product 2,2 bottom of product
Portion sets gum-injecting port 4, and gum-injecting port 4 sets injected rubber hose 7,7 connection glue injection barrel 5 of injected rubber hose, and injecting glue barrel 5 is located at product 2 most
On high point sustained height, the vacuum bagging skin of 2 minimum point of product places a pressure inductor 3, for controlling the height of injecting glue barrel
Degree, if the registration of pressure inductor 3, more than 1000mbar, height controller 8 automatically controls injecting glue barrel and declines to tie up
It is constant to hold inductor registration, finally, position and the quantity of gum-injecting port 4 are set according to the size of product, the position of gum outlet 4 is set
At the peak of product.Gum outlet 4 connects out sebific duct 6, goes out the height of sebific duct 6 peak between and flushes.
A kind of new vacuum imports the technique of shaping big height difference product, and gum-injecting port 4 is arranged to the bottom of product 2,
Gum-injecting port 4 sets injected rubber hose 7, and 7 connection glue injection barrel 5 of injected rubber hose, injecting glue barrel 5 is promoted to and the same height of product peak
Degree, then, the vacuum bagging skin of product minimum point place the height that a pressure inductor 3 is used to control injecting glue barrel, if pressure
The registration of power inductor automatically controls injecting glue barrel and declines to maintain inductor to show more than 1000mbar, then height controller 8
Number is constant, finally, sets the position of gum-injecting port 4 and quantity, the position of gum outlet 4 to be arranged at product most according to the size of product
At high point, the position of gum outlet 4 is arranged at the peak of product.Gum outlet 4 connects out sebific duct 6, goes out the height of sebific duct 6 therewith
Between peak flush.
