Abstract
Foamed instrument panel peripheral sealing technique is related to automotive upholstery processing technology.Mainly solve existing foamed instrument panel peripheral sealing technique there are material leakage, lack the problems such as material and invent.Instrument board front porch area uses the sealing means of soft seal, and gas-flow closure item is placed in foaming mould U-type groove；The both ends of gas-flow closure item are inserted on inflation core port；Foaming mould is heated, epidermis being adsorbed on cover half in epidermis laying to cover half, instrument board framework being placed on epidermis, dynamic model and cover half mold, instrument board arranged on left and right sides copper billet is pressed on epidermis under cylinder drive, and inside is withstood on by dynamic model and plays sealing function on instrument board framework.Sealing function can be played by being crimped in sealing bar close to major and minor driving side position by foaming mould active and inactive mold interaction force.It can be pressed onto front of dash after gas is full of in sealing strip, play sealing function.Advantage be foamed products will not material leakage, do not occur lack material the problems such as.
Description
Technical field:
The present invention relates to automotive upholstery processing technology, the peripheral sealing work that is specifically related in foamed instrument panel process
Skill.
Background technique:
High to automobile interior decoration quality and feel requirement since automobile industry rapidly develops, for medium-to-high grade car-shaped, foaming is
Indispensable technique, foamed forming process are as follows: epidermis is formed by roto casting, and slush moulding epidermis after molding is put into
In foaming mould, epidermis is adsorbed on cover half by adsorption function, is then placed in skeleton, foaming mould molding is being sent out later
It steeps and injects polyhydric alcohol conjugate material and isocyanates (being commonly called as A material, B material) in mold, there are also a small amount of catalyst, by chemically reacting,
Foaming is carried out in a mold.
Existing foamed instrument panel peripheral sealing technique there are periphery material leakage, occur bubble, lack material etc. product defects.
Summary of the invention:
Technical problem to be solved by the invention is to provide one kind will not material leakage, do not occur bubble, lack material etc. product quality problems
Foamed instrument panel peripheral sealing technique.
Above-mentioned purpose is achieved in that
One, instrument board front porch area uses the sealing means of soft seal.
Specific method is: opening U-type groove to the foaming mould being located at instrument board front porch area, gas-flow closure item is placed on
In U-type groove；The silicone tube and silica gel strip that gas-flow closure item is nested together by two form, and the outer diameter positioned at the silicone tube of outside is
10 millimeters, internal diameter is 7 millimeters；Selecting the cross section that diameter is 6.7 millimeters is that the petal silica gel strip of four leaves is mounted on silicone tube
It is interior；The both ends of gas-flow closure item are inserted on inflation core port；
Two, instrument board arranged on left and right sides is sealed using copper billet (sliding block), i.e., hard sealing.Close to major and minor steering position using hard close
Envelope.
Specific method is: before being foamed, will first be cleaned out in mold cavity with high pressure air blowing, is added later with water
When foaming mould is heated to 45 DEG C or so by heat, (cover half has adsorption hole) in epidermis laying to foaming mould cover half passes through
Epidermis is adsorbed on cover half by adsorption function, and then instrument board framework is placed on epidermis, and dynamic model is under cylinder promotion and fixed
Mould molding is to together, and instrument board arranged on left and right sides copper billet starts to move to instrument panel under cylinder drive later, and copper billet is pressed in
On epidermis, inside is withstood on instrument board framework by dynamic model, under interaction force, can play sealing function.
Close to major and minor driving side position, foaming mould active and inactive mold interaction force is directly leaned on, is crimped in sealing bar
Play sealing function.
When foamed material is filled into epidermis and instrument board framework, it may occur that chemical reaction generates gas, at this time sealing strip
In non-working condition, after gas is discharged by front of dash, inert gas is filled into sealing strip at this time, and sealing strip starts
It works, after gas is full of in sealing strip, front of dash can be crimped onto, sealing strip plays sealing function.
The invention has the advantages that foamed products will not material leakage, do not occur bubble, lack material etc. product quality problems, improve produce
Quality.
Specific embodiment:
One, instrument board front porch area uses the sealing means of soft seal.
Specific method is: opening U-type groove to the foaming mould being located at instrument board front porch area, gas-flow closure item is placed on
In U-type groove；The silicone tube and silica gel strip that gas-flow closure item is nested together by two form, and the outer diameter positioned at the silicone tube of outside is
10 millimeters, internal diameter is 7 millimeters；Selecting the cross section that diameter is 6.7 millimeters is that the petal silica gel strip of four leaves is mounted on silicone tube
It is interior；The both ends of gas-flow closure item are inserted on inflation core port；
Two, instrument board arranged on left and right sides is sealed using copper billet (sliding block), i.e., hard sealing.Close to major and minor steering position using hard close
Envelope.
Specific method is: before being foamed, will first be cleaned out in mold cavity with high pressure air blowing, is added later with water
When foaming mould is heated to 45 DEG C or so by heat, (cover half has adsorption hole) in epidermis laying to foaming mould cover half passes through
Epidermis is adsorbed on cover half by adsorption function, and then instrument board framework is placed on epidermis, and dynamic model is under cylinder promotion and fixed
Mould molding is to together, and instrument board arranged on left and right sides copper billet starts to move to instrument panel under cylinder drive later, and copper billet is pressed in
On epidermis, instrument panel is withstood on instrument board framework by dynamic model, under interaction force, can play sealing function.
Close to major and minor driving side position, foaming mould active and inactive mold interaction force is directly leaned on, is crimped in sealing bar
Play sealing function.
When foamed material is filled into epidermis and instrument board framework, it may occur that chemical reaction generates gas, at this time sealing strip
In non-working condition, after gas is discharged by front of dash, inert gas is filled into sealing strip at this time, and sealing strip starts
It works, after gas is full of in sealing strip, front of dash can be crimped onto, sealing strip plays sealing function.
