Background technology
Domestic this type of radiator grid is in order to make the automobile-exterior overall appearance at present, often make the radiator grid in its place ahead have glittering metallic luster, normally adopt electroplating technology in the prior art, cover the ABS substrate surface by current potential official post metal chromium ions, form the glittering grid in overhang surface, but electroplating cost is too high, and contaminated environment.Thereby insider's new alternative method of always concentrating on studies.
Although also have several different methods to form pattern or gloss at body surface, but because automobile grid total length is long, be about about 622mm, be special-shaped song structure again, as shown in Figure 1, its 21 protruding lattice of vertical bar are seen its two ends angle position near 90 degree rectangular shaped from the vertical face direction of grid, and 5 the protruding lattice and other the length variation in centre position are bigger, want to be formed uniformly on its surface the metal level not a duck soup.
Summary of the invention
At the defective of prior art, the purpose of this invention is to provide simple, the economic environmental protection of a kind of technology and guarantee that the radiator grid surface reaches the hot stamping method of aesthetic.
Method of the present invention comprises: grid is fixed on the anchor clamps, the silica gel mould is fixed in heat-generating disc goes to the bottom, and stamping systems occupy between silica gel mould and the grid, during thermoprint, stamping systems is transferred to being layered on grid surface, heat-generating disc was heated to at least 250 ends Celsius, and the heat-generating disc and the first silica gel mould move downward to the pressure of grid surface pressure-bearing silica gel mould then, treat that thermoprint finishes, on carry heat-generating disc and silica gel mould, tear the peel ply of stamping systems off, modify burr, get final product to such an extent that have a thermoprint grid of metallic luster.
The present invention can be divided into grid at least three grid sections, and each grid section cooperates one pair of silica gel mould and heat-generating disc respectively, and successively each grid section is carried out thermoprint in order.
Blocking point the best is 250 degrees centigrade.
The present invention adopts hot stamping process, and grid is divided into plurality of sections, and hot stamping equipment is also corresponding to be divided into some parts, every part scale is less, if a place damages, only needs to change corresponding part and need not change whole thermoprint mould, thereby from actual effect see the investment little, maintenance cost is low; Hot stamping process carries out on every part successively according to the curved surface structure of grid in addition, and the control of every part is simpler, and the qualification rate height is decorated and the selectivity decoration for the part, and the thermoprint operation is simple and free from environmental pollution to have the feature of environmental protection.

Fig. 2 is the side view of automobile radiators grid;
Fig. 3 is a hot stamping method schematic diagram of the present invention.
The specific embodiment
Since radiator grid product structure complexity, thereby adopt the segmentation hot stamping method, promptly adopt dull and stereotyped blanching seal technology, to the thermoprint one by one respectively of each thermoprint face.As shown in Figure 2,21 protruding lattice of radiator grid 1 are divided into three thermoprint faces 11,12 and 13 according to curvature, comprise two side section and interlude respectively.
When implementing thermoprint, as shown in Figure 3, at first thermoprint grid 1 is fixed on the anchor clamps 2.The pellosil 3 corresponding thermoprint faces that are used for thermoprint are also made three covers 31,32 and 33 respectively, and this three covers silica gel mould is separately fixed at the below of heat-generating disc 4, is stamping systems 5 between silica gel mould and the thermoprint face.During thermoprint, at first with the first thermoprint face 11 and the first silica gel mould, 31 position centerings, heating heat-generating disc to 250 degree centigrade, put down stamping systems 5, simultaneously the heat-generating disc and the first silica gel mould move downward to the pressure of the first thermoprint face, 11 pressure-bearing silica gel moulds, treat that thermoprint finishes, on carry heat-generating disc and silica gel mould, tear the peel ply of stamping systems 5 off, modify burr, get final product to such an extent that have first a thermoprint grid section of metallic luster.In like manner, can carry out thermoprint to second and third thermoprint face successively, thereby obtain second and third thermoprint grid section.
Described stamping systems 5 is an electrochemical aluminum foil.The order of thermoprint can be from any part.
The foregoing description divides three process to finish thermoprint, thereby but also grid can be divided into more multistage and divide more multiple working procedure to finish thermoprint.
The heating-up temperature of described heat-generating disc also can be 200 or 300 degrees centigrade, or other temperature between 200 to 300 degrees centigrade.
The present invention selects the segmentation hot stamping process for use, it is many that whole hot stamping process of the input ratio of its operation and mould wanted, but because the whole thermoprint face of this grid product is the shape of an irregular similar sphere, as pressing three thermoprints, promptly little each thermoprint reduction of area, especially the centre position obviously dwindles, because the thermoprint area dwindles, the degree of deformation that the injection moulding process of the thermoprint face after this dwindles produces lowers greatly with respect to whole face, the area of each thermoprint silica gel mould has also dwindled simultaneously, has reduced the degree of deformation of silica gel mould in manufacture process to a great extent.So the distortion of the actual thermoprint scope of grid and silica gel mould is all lowered as far as possible, has improved both applying degree when thermoprint, thereby improve the stability of thermoprint.Thereby from actual effect, this segmentation thermoprint input-output ratio is better.Simultaneously, when dividing three sections thermoprints, the manufacturing cost of each thermoprint silica gel mould reduces greatly than whole one, when when daily production, occurring damaging, only need to change the silica gel mould of damaged location, and need change whole silica gel mould when need not a whole thermoprint, so can save daily consumables cost.In addition, dwindle each thermoprint face and can increase the desirable hot stamping effects area that blocking film wraps up protruding lattice surface, because dwindle each thermoprint area, can imagine after spreading blocking film on the thermoprint face of each section, blocking film can wrap up thermoprint face and unruffled ideal effect scope can increase than whole (21 protruding lattice) thermoprint face, so the segmentation thermoprint can suitably increase the thermoprint scope.
Only in order to explanation and unrestricted the present invention, those skilled in the art should know that the present invention also has other replacement step to above embodiment, in not breaking away from category of the present invention, all should belong to protection scope of the present invention.
