Abstract
The invention relates to a method for processing a cold-hot water pipe of a turbulent flow polyurethane (PUR) foaming mold of an automobile. The method mainly comprises the following steps of firstly performing mold flow analysis at an early stage of a mold design to find a deformation point and the deformation direction; then adding a plurality of water channels on the mold to apply cold water at an outward-deforming position of a water pipe product; and applying hot water at the inward-deforming position of the product to enable the product to produce reversible deformation, wherein the product does not deform after cooled. The method for processing the cold-hot water pipe of the PUR foaming mold of the automobile has the advantages of improving a shape-righting mode, dispensing with steps of roasting and manual shape righting, facilitating simplification of processing steps, being capable of effectively reducing the production cost and facilitating improvement of the quality of automobile turbulent flow products.
Description
Technical field
The present invention relates to the foaming mould process technology, relate in particular to a kind of hot water pipe processing method of automobile flow-disturbing PUR foaming mould.
Background technology
Automobile-used disturbing flow device refers to that generally car can produce and the ejusdem generis active force of lift under steam, and just opposite direction utilizes this downward power to offset lift on the vehicle body, thus ensured driving safety because.Because car body generally is an irregular streamline body, vehicle separates air, and air flows through from vehicle's surroundings, and after flowing through roof, this part air can begin to flow downward, and the flowing velocity of air-flow can determine according to the shape of the tailstock here; Such as, the tailstock is for more attractive in appearance, a lot of tailstock moulding are steeper all, so air velocity also can be faster, the effect that also will form as wing obtains lift upwards, and the effect of using spoiler is exactly to reduce suffered climbing power in the Vehicle Driving Cycle under the prerequisite that does not increase car body weight.Because how long the hot water pipe product of automobile flow-disturbing PUR foaming mould has 1 meter, width only has 70mm, product is out of shape easily, prior art is after product is processed, the product of distortion is put into baking box carry out high-temperature baking, then product is fixed on the anchor clamps orthopedicly, makes it eliminate distortion, thereby caused unnecessary loaded down with trivial details processing.
Summary of the invention
For above defective, the invention provides a kind of need not to enter baking and manually orthopedic, be conducive to simplify procedure of processing, can be effectively than the hot water pipe processing method of the automobile flow-disturbing PUR foaming mould of low production cost, with many deficiencies of solution prior art.
For achieving the above object, the present invention is by the following technical solutions:
A kind of hot water pipe processing method of automobile flow-disturbing PUR foaming mould mainly is comprised of following steps:
(1) at first, at Design of Dies in earlier stage, product is carried out mold flow analysis, find out deformation point and deformation direction;
(2) then, increase some water channels at mould, the water pipe product position that will outwards be out of shape first applies cold water; To apply hot water to enterolithic product position again, impel the product formation reversible deformation, indeformable after the product cooling.
The beneficial effect of the hot water pipe processing method of automobile flow-disturbing PUR foaming mould of the present invention is: in die design process, product is carried out mold flow analysis, find out its deformation point and deformation direction, then increase water channel at mould, with the product position that outwards is out of shape, add cold water, will be to enterolithic product position, heating water, impel the product formation reversible deformation, make after the product cooling indeformablely, improved mode orthopedic on the conventional brace, need not to enter baking and manually orthopedic, be conducive to simplify procedure of processing, can effectively than low production cost, be conducive to improve the quality of automobile flow-disturbing product.
Description of drawings
The below is described in further detail the present invention with reference to the accompanying drawings.
Fig. 1 is the hot water pipe machining sketch chart of the described automobile flow-disturbing of embodiment of the invention PUR foaming mould;
Fig. 2 is the hot water pipe process side view of the described automobile flow-disturbing of embodiment of the invention PUR foaming mould.
The specific embodiment
Shown in Fig. 1-2, the hot water pipe processing method of the described automobile flow-disturbing of embodiment of the invention PUR foaming mould mainly is comprised of following steps:
(1) at first, at Design of Dies in earlier stage, product is carried out mold flow analysis, find out deformation point and deformation direction;
(2) then, increase some water channels at mould, the water pipe product position that will outwards be out of shape first applies cold water; To apply hot water to enterolithic product position again, impel the product formation reversible deformation, indeformable after the product cooling.
Above embodiment is the more preferably specific embodiment a kind of of the present invention, the common variation that those skilled in the art carry out in the technical program scope and replace and should be included in protection scope of the present invention.
Claims (1)
1. the hot water pipe processing method of an automobile flow-disturbing PUR foaming mould is characterized in that, mainly is comprised of following steps:
(1) at first, at Design of Dies in earlier stage, product is carried out mold flow analysis, find out deformation point and deformation direction;
(2) then, increase some water channels at mould, the water pipe product position that will outwards be out of shape first applies cold water; To apply hot water to enterolithic product position again, impel the product formation reversible deformation, indeformable after the product cooling.
