Specific embodiment

A kind of hot pressing die suitable for multiple-die press, is shown in Fig. 2~Fig. 4：It includes upper bolster 1, die shoe 2, upper die plate 3rd, lower template 4, lower template 4 is supported on die shoe 2, and the center of lower template 4 is provided with V-type indent knife on alongst Groove 5, the minimum intersection of V-type indent cutter groove 5 caves in downwards a straight trough 6 with width, and the lower section of upper bolster 1 is fixed with Template 3, the lower surface of the both sides length direction of upper die plate 3 is fixed with respectively the thick positive stop strips 7 of 8mm, and upper die plate 3 corresponds to V-type The surface of indent cutter groove 5 be disposed with length direction arrangement under convex V-knife 8, under convex V-knife 8 point of a knife 9 towards straight trough 6 Centrage arrange, under convex V-knife 8 the matched moulds state of point of a knife 9 under can be built in completely in V-type indent cutter groove 5, upper die plate 3, lower mould It is respectively arranged with the length direction of plate 4 in some through holes 10 being arranged in parallel, through hole 10 and is fitted with heating rod 11, plus Hot pin 11 is used to heat mould, reaches hot pressing temperature.

Upper die plate 3 corresponds to down the installation position of the cutter hub 12 of convex V-knife 8 and is provided with mounting groove 13, mounting groove 13 it is upper Portion is wide opening structure 14, under the cutter hub 12 of convex V-knife 8 be flush-mounted in corresponding mounting groove 13；

The thick FR4 plates 15 of 2mm are respectively disposed with the upper surface of upper bolster 1, the lower surface of die shoe 2, its be used for it is heat-insulated, Ensure safety；

The point of a knife 9 of the thickness of positive stop strip 7 convex V-knife 8 under guaranteeing is deep in V-type indent cutter groove 5 rear and V-type indent cutter groove 5 inwall leaves gap H, and gap H is the thickness of material；

The width of straight trough 6 is 0.3mm, it is ensured that be not in bright border phenomenon during wheat drawing hot pressing；

The concrete numerical value for extending out angle [alpha] cutter head angle β of convex V-knife 8 with of V-type indent cutter groove 5 is according to pressing readjustment Angle is adjusted design, it is ensured that hot-forming product meets design requirement.

Its operation principle is as follows：Mould is heated beforehand through heating rod 11, the wheat of rubberizing is drawn along length Direction enters the upper surface for being laid in lower template 4, and the length direction two ends that wheat is drawn are flattened, and afterwards upper bolster 1 drives upper die plate 2nd, the downward actuation of convex V-knife 8 under, under the point of a knife 9 of convex V-knife 8 push towards treating bending length line, the both sides that wheat is drawn form folding Kinking structure, the outer length direction two ends of bending region are default scrap area, and Mai Lajuan adopts leapfrog bending, institute after bending The product of generation has by microtome or plectrum machine plectrum blanking because the minimum intersection of V-type indent cutter groove 5 caves in downwards One straight trough 6 with width, straight trough guarantees bending part without bright border.

The specific embodiment of the present invention has been described in detail above, but content is only the preferable enforcement of the invention Example, it is impossible to be considered as the practical range for limiting the invention.All impartial changes made according to the invention application range Change and improve etc., all should still belong within this patent covering scope.
