Description
Technical field
The present invention relates to a kind of hollow box body and its forming method, specifically a kind of hollow box body with foaming layer
And its forming method, belong to hollow box body technical field.
Technical background
Automobile plastic fuel tank has prominent advantage, particularly lightweight, higher product with respect to metal fuel tank
The aspects such as configuration design degree of freedom, substituted metal fuel tank substantially.With the reinforcement of social environment protective awareness, people are to vapour
The requirement also more and more higher of garage's industry energy-saving and environmental protection, in recent years, plug-in hybrid-power automobile and stroke-increasing electric automobile are gradually
Become the study hotspot of each main engine plants.But, generally, plug-in hybrid-power automobile and stroke-increasing electric automobile only by
Motor-driven, electromotor is chronically at off position, with the exchange of day and night temperature change and fuel tank internal heat, combustion
Fuel in fuel tank, such as gasoline, the larger temperature difference can be produced, thus leading to higher fuel-steam pressure, in some cases even
Up to 35kpa.Now, with respect to the voltage endurance capability of metal fuel tank, performance is particularly not enough, is in a disadvantageous position for plastic fuel tank.With
When, because plug-in hybrid-power automobile and stroke-increasing electric automobile do not start electromotor for a long time, background noise reduces, and leads to fire
The noise that oil rocks generation in fuel tank is easy to be delivered on vehicle body by oil tank wall, is perceived by passenger, and then reduces client
Drive to experience.Therefore, work out a kind of heat-insulated, sound insulation, pressure, and light-weighted plastic fuel tank is extremely urgent.
At present, the main solution of each plastic fuel tank manufacturer has:
1) pass through to insert reinforcing member inside fuel tank, to improve the inner pressure resistant ability of fuel tank, but the method cannot
Meet fall-down test and the pv performance test of fuel tank simultaneously；
2) by producing many walled oil tanks, the performances such as rigid, the heat-insulated, sound insulation of fuel tank are improved.As:
A the us20110215102a1 patent of (), ti company application, describes a kind of fuel tank with inside and outside wall, inwall with
Outer wall section connects, to provide the gap between inside and outside wall, outer wall and inwall priority by tubular parison formation.The method produces
Cycle is very long, and is extremely difficult to expected conception by tubular parison, inner wall shape also more difficult control.
B the de102011113845a1 patent of (), kautex company application, describes a kind of fuel oil with protective case
Case, this protective case is that advance comprising is good, and it must contain outer layer (fiber-reinforced layer) and hard foamed layer, and protective case is in parison
Blanking is put in mould half module by robot before completing.This method increase the manufacturing cost of fuel tank body, and fuel tank
Weight also greatly improve.Further, since protective case is well prepared in advance, it is impossible to ensure relatively when boning with fuel oil tank shell
Good interlayer adhesion；Protective case is put in mould half module, can stop the steam vent on mould half module, leads to protective case and parison
Between gas be difficult to discharge, leave a large amount of bubbles in protective case and fuel oil tank shell bonding part；Protective case cannot be realized to fuel oil
The full parcel of case, must leave gap at fuel tank half line, lead to still have heat exchange phenomenon at this it is impossible to reach very well
Effect of heat insulation.
