1. a kind of molding production method of resin protection shell for digital product, includes the following steps:

  • The first step coats at least one layer of semi-solid preparation epoxide resin material and at least one layer of fibrous material, forms the object of layer structureMaterial;

    Second step is handled using mould heat pressure, and mold includes upper die and lower die, the cooling system and control system that upper mold is arranged in,Movable heat-generating disc is provided between upper die and lower die, lower die is provided with movable mold core, and movable mold core is provided with location hole, will be resistance toThe silica gel piece or silica gel of high temperature are mounted on movable mold core, and the material that the first step is completed is placed on to the silica gel piece or silica gel sheath of lower dieOn, then shaped sheet is placed on to the top of material again;

    Third step controls heat-generating disc by control system and reaches above movable mold core, and heat-generating disc temperature is maintained at 180~400DEG C, baking time is 10~30s, softens shaped sheet, and after baking time, heat-generating disc retracts automatically, then mold again,Upper mold pushes, and the dwell time is 10~30s, and upper mold rises after molding, by molding protection shell for digital product together with movable mold coreIt takes out together;

    Protection shell for digital product and activity mold core that third step completes are put into the high temperature resistant bag of sealing, resistance to height by the 4th stepWarm bag passes through vacuumize process, and movable mold core sum number code product protection shell is made to reinforce setting;

    Or third is clamped by jigThe protection shell for digital product to complete and movable mold core are walked, movable mold core sum number code product protection shell is made to reinforce setting;

    5th step, puts movable mold core sum number code product protection shell into oven again and carries out second and solidify, and curing time is 20~60 minutes, the temperature in oven maintained 80~150 DEG C, made protection shell for digital product curing molding;

    6th step cuts protection shell for digital product using CNC machine or laser cutting machine, deburring cut hole, will be digitalProduct protection shell is separated with movable mold core, is then reused polissoir or is manually polished protection shell for digital product, thrownLight grinds off the burr of protection shell for digital product, and protection shell for digital product finished product is made.
