The specific embodiment
Further set forth the present invention below in conjunction with accompanying drawing.
The method of a kind of rapid forming mold of the present invention comprises the steps: that (1) scribe the product entity prototype; (2) according to the product entity prototype, replicated product time prototype, inferior interior benevolence lid, and make low mold frame and upper bolster; (3) product time prototype, inferior interior benevolence lid are fixed in upper bolster, low mold frame and counterdie locked mode accessory are installed then; (4) moulding counterdie; (5) die sinking dismounting time interior benevolence lid; (6) upper bolster and the patrix locked mode accessory that unloads after next interior benevolence is covered is installed; (7) moulding patrix; (8) die sinking dismounting low mold frame, upper bolster and product time prototype obtain die needed.
In one embodiment of the invention, with reference to figure 1-4, product time prototype label is 21, and inferior interior benevolence lid label is 20, and the upper bolster label is 30, and the low mold frame label is 31.
In step (2), replicated product time prototype 21, inferior in benevolence lid 20 can adopt following dual mode: 1) by duplicating 1: 1 soft master mold of assembling replicated product time prototype 21, inferior in benevolence lid 20; (2) by electroforming master mold shell, assembling 1: 1 just master mold and replicated product time prototype 21, inferior in benevolence lid 20.Wherein, make described product time prototype 21, inferior in the material of benevolence lid 20 should adopt that heatproof more than 400 ℃, coefficient of thermal expansion are little, the strong and unyielding property of tool, easily cut the material of disassembling, for example, silicon rubber.
With reference to figure 5, in step (3), at first product time prototype 21, inferior interior benevolence lid 20 are fixed on the upper bolster 30; Then, with reference to figure 6, low mold frame 31 and locked mode accessory (not shown) are installed.Then, in step (4), with reference to figure 7, moulding counterdie 41.In the present invention, described counterdie 41 can be by mode moulding such as pressure injection, ejaculation, perfusions, wherein, described counterdie 41 used materials need 180 ℃ of normality constant temperature indeformable, be not stained with the material of glue, acid and alkali-resistance, the strong and unyielding property of tool, for example, nylon, plastic-steel, ABS materials such as (acrylonitrile-butadiene-styrene (ABS)s), perhaps low-melting-point metal such as tin, ashbury metal etc.
