Abstract
The invention discloses a method for producing a sealing structure of an automobile skylight. The method comprises steps as follows: Step 1, prefabrication of a spring: the spring is made of 60Si2MnA; Step 2, production of a sealing structure body: the spring is placed into a mold according to the design requirement, rubber is injected into the mold by the aid of a rubber injecting machine, and the sealing structure body is produced through pressure maintaining, vulcanization and demolding; Step 3, detection of the sealing structure body: airtightness, waterproofness, pressure resistance and ageing resistance tests are performed on the produced sealing structure body; Step 4, the sealing structure body is mounted on an automobile skylight frame by the aid of a sealant. A slot is formed in the inner side surface of a first sealing strip, so that the condition that the service life of the first sealing strip is affected due to deformation caused by excessive extrusion during bending of the first sealing strip is avoided. The spring is fixedly arranged in a base and plays a role in assisting the sealing structure body in quickly recovering from deformation, and the condition that the airtightness is affected due to rubber ageing of the sealing structure body due to repeated deformation is avoided.
Description
Technical field
The invention belongs to automobile sealed technical field, be specifically related to a kind of method making Car Skylight Sealed Construction.
Background technology
Along with the fast development of auto-industry and the raising day by day of living standards of the people, people also focus on the traveling comfort of automobile, health consider the safety and reliability of automobile when buying automobile while more.Air conditioning for automobiles belongs to one of car comfort module, and the air-tightness of air conditioning for automobiles self has vital impact to heat pump performance and noise.
Skylight is installed on car roof, can effectively make car inner air flow, increases entering, for car owner brings health, comfortable enjoyment of fresh air.Vehicle dormer window simultaneously automotive window also can widen the vision, and is also usually used in the shooting demand of travelling shot shooting.Traditional vehicle dormer window is in the process used, adhesive tape is aging there will be drainage, its mainly aging reason in the extruding being subject to vehicle dormer window for a long time, the adhesive tape in skylight is sticked together, do not have the effect of waterproof, owing to being subject to the extruding of vehicle dormer window for a long time, the adhesive tape of vehicle dormer window is short for service life.
Summary of the invention
The object of the present invention is to provide a kind of method making Car Skylight Sealed Construction, solve vehicle dormer window sealing member easily aging, distortion in prior art, the technical matters of poor sealing performance.
In order to solve the problems of the technologies described above, the present invention takes following technical scheme:
Make a method for Car Skylight Sealed Construction, comprise the steps:
Step one, prefabricated spring, the material of described spring is 60Si2MnA;
Step 2, make hermetically-sealed construction body, spring is put into mould according to designing requirement, rubber injection machine is adopted to inject rubber in mould, and through pressurize, sulfuration, depanning is to hermetically-sealed construction body, described hermetically-sealed construction body comprises base and is arranged on the first sealing band and second sealing band on base top, described chassis interior is provided with spring, the length of the first sealing band is greater than the second sealing band, and the first sealing band bends to the second sealing band, the inner side of the first sealing band is provided with multiple notch, described notch is arc-shaped, described hermetically-sealed construction body is made up of poly-chloroprene rubber and natural rubber,
Step 3, inspection hermetically-sealed construction body, step 2 terminates rear needs and carries out air-tightness, water tightness, resistance to compression, antiageing test to made hermetically-sealed construction body, makes it meet design requirement;
Step 4, adopt sealant to be arranged on auto sunroof framework the hermetically-sealed construction body be up to the standards through step 3, and check the air-tightness between hermetically-sealed construction body and auto sunroof framework and water tightness.
When automobile skylight glass is opened, the first sealing band is in nature extended configuration; In automobile skylight glass closing process, the first sealing band thrust given by skylight glass, first sealing band bends to the second sealing band, when automobile skylight glass is closed completely, the outside face of the first sealing band and the interior side contacts of skylight glass, skylight glass extrudes the first sealing band and plays sealing function, and the end of the first sealing band contacts with the second sealing band.The inner surface of the first sealing band offers notch, avoids its transition in BENDING PROCESS extrude and be out of shape, affects its service life.By being fixedly installed spring in base, spring plays use Monday helping the fast quick-recovery deformation of hermetically-sealed construction body, and prevent because repeated deformation, hermetically-sealed construction body rubber is aging, affects air-tightness.
Further improvement, described first sealing band surface is globoidal structure, improves its deformation nature, if this surface is plane, be then out of shape larger in BENDING PROCESS, repeated deformation will speed up aging.
Further improvement, described second sealing band surface is globoidal structure, if this surface is plane, be then out of shape larger in BENDING PROCESS, repeated deformation will speed up aging.
Further improvement, described hermetically-sealed construction body base cross section is trapezoidal, and the both sides waist of described trapezoidal base is cambered surface.Three-dimensional-structure increases its stability, ensures sealing effectiveness.
The present invention compared with prior art, has following beneficial effect:
1, by sealing lip is arranged to echelon form, trapezoidal sealing band upper base is provided with arc edge sealing, and in trapezoidal sealing lip, be provided with multiple adhesive-proof strip, can prevent that adhesive tape is aging there will be drainage, after avoiding being subject to for a long time the extruding of vehicle dormer window, adhesive tape sticks together the drainage caused, and the service life further increasing vehicle dormer window sealing lip is short.
2, the inner surface of the first sealing band offers notch, avoids its transition in BENDING PROCESS extrude and be out of shape, affects its service life.
3, by being fixedly installed spring in base, spring plays use Monday helping the fast quick-recovery deformation of hermetically-sealed construction body, and prevent because repeated deformation, hermetically-sealed construction body rubber is aging, affects air-tightness.
