Description
Technical field
The utility model belongs to automobile machine-shaping technical field, is specifically related to a kind of safe automobile air bag tear line shaped device.
Background technology
The body and mind impressions direct and driver and crew of the internal environment of automobile are closely related, and interior trim is stressed sense of touch, feel, comfortableness and sight etc.Semihard maceration matter instrument board is between epidermis and skeleton, to be filled with polyurethane foam, has both improved sense of touch, gives a kind of comfortable luxurious sensation of people, has the function of absorbing impact energy again simultaneously, is used on the medium-to-high grade car more.Along with people's to outward appearance, function and the security of automotive upholstery require increasingly high; The demand of attaching the gasbag-type instrument board strengthens; The instrument board of more and more vehicles is designed to seamless air bag instrument board; Both do not had visual attaching line, and can guarantee that again air bag normally opened, and processed an air bag tear line in instrument board reverse side air bag district and can from instrument board, rush out after the air bag blast guaranteeing.
At present, the reduction technology of seamless air bag instrument board is divided into integral type reduction and two kinds of patterns of multiple step format reduction usually.The former is that epidermis, froth bed and skeleton weaken simultaneously; The latter is that epidermis weakens separately, and froth bed and skeleton weaken simultaneously.Wherein the instrument board epidermis can pass through cryoprobe, hot cutter, laser or the reduction of other technology after moulding, forms tear line in the air bag zone, rush out during the explosion of air feed capsule, but these methods needs special equipment, and operation is many, and the cycle is long, and cost is higher.
The slush moulding epidermis is the forming temperature that the slush mold that will have surface detail earlier is heated to the slush moulding epidermis; Then with powder case and slush mold fastening; Through the rotation slush mold; Make slushing powder under the effect of gravity and heat, coating, fusion equably, adhere to the whole surface of die cavity, make epidermis through cooling and shaping.Slush moulding epidermis texture is evenly attractive in appearance, and is soft comfortable, and the epidermis internal stress is little, and thickness is even, has better elastic, resistance to ag(e)ing and low-shrinkage and mechanical performance.Therefore roto casting is being widely used in recent years.
Patent US20080315566A1 has introduced stealthy air bag door cover plate of a kind of fascia and manufacturing approach thereof; This patent is passed through moulding technology earlier; Utilize the feature templates in the mold cavity; At the inboard tear seam that forms of ground floor epidermis, tear seam extends from the inboard of epidermis laterally, but does not penetrate.Utilize delineation equipment on the inboard tear seam of epidermis, to carve tear line then, tear line continues to extend to the epidermis outside from the tear seam low side, but does not penetrate, and the residual thickness of score can accurate be controlled.The epidermal laceration wire shaped of utilizing this method to form has " H ", " V ", " I " type etc.But the shortcoming of this patent is that process is complicated, in mold cavity, has the feature templates, also will increase special delineation equipment, and cost is higher.
Patent US6139049A has introduced a kind of ultraviolet irradiation that utilizes the air bag cuticle region has been carried out the technology that photodissociation forms the air bag tear line.The instrument board characteristic that this method is produced is that photodissociation takes place the one side of epidermis at least easily; An important device is a ultraviolet generater; Regional in order to control the ultraviolet photodissociation of epidermis in technical process; Need select corresponding photodissociation auxiliary agent and photodissociation inhibitor for use, at the tear line that air bag zone formation needs, prevent the skin material photodissociation at non-air bag zone passage photodissociation inhibitor through the photodissociation auxiliary agent.The principle of photodissociation auxiliary agent and inhibitor all is through changing the wavelength realization that ultraviolet generater produces ultraviolet light.It is good that the air bag tear line that this technology forms is hidden property, but owing to increase ultraviolet generater, cost is higher.
Patent US5530057 and US5567357 have introduced a kind of method of utilizing raw material powder to make general safety air bag tear seam.Different with other regional epidermis raw materials of instrument board, the raw material that is used to make air bag zone epidermis contains filler, like glass microsphere or material with carbon element; Make the epidermis intensity in air bag zone less than other zones; Different qualities through epidermis forms the tear line of air bag, and the air bag tear seam that this method is made is disguised strong, but technological process is complicated; The cost of material is high, is difficult for large-scale promotion.
In sum, the epidermis tear line reduction technological process of existing fascia air bag zone is complicated, and is high to the requirement of equipment input, and the production cycle is longer.
The utility model content
The purpose of the utility model is exactly to overcome the defective of above-mentioned prior art and a kind of safe automobile air bag tear line shaped device is provided, with the new breakthrough that realizes that seamless air bag tear line is made.
For realizing above-mentioned purpose, the utility model provides a kind of safe automobile air bag tear line shaped device, comprises mould, and powder box also comprises post patch, anchor post, height adjuster, portable stanchion, clamping device, template.Post patch is installed on the powder box bottom; Anchor post is installed on the post patch; Portable stanchion is connected with anchor post through height adjuster; The bottom of portable stanchion is equipped with clamping device, connects template through clamping device, and template is precisely regulated through height adjuster to the distance H of mold bottom 3.
Height adjuster is the electronics display instrument, and intelligence is regulated the distance H 3 of template to mold bottom, and H3 is the residual thickness of tear line.
The diameter Q2 of portable stanchion is smaller or equal to the diameter Q1 of anchor post, to guarantee the firm, stable of whole pillar system.
Said template has multiple shape, is selected from " U ", " V ", " H ", " I ", " O ", " C ".
The cross-sectional width scope of said template is the 0.1-10 millimeter.
The cross-sectional width scope of said template further is preferably the 0.5-2 millimeter.
Said clamping device is preferably screw clamp means.
The innovative point of the utility model is:
(1) simplified epidermal laceration line reduction technological process, promptly in the epidermis forming process, accomplished reduction technology, shortened the cycle of reduction technology, reduced production costs;
(2) mould with become an individual system after powder box combines; Pivot; Whole system is because the support of anchor post and portable stanchion and unusual more stable and stronger; In case adjusted the system height with height adjuster, the thickness of tear line also can be controlled so, has realized seamless air bag tear line manufacturing new technology.
