Manufacturing method of silicon carbide mold for glass molding and silicon carbide mold
The invention belongs to the technical field of silicon carbide molds, and particularly relates to a manufacturing method of a silicon carbide mold for glass molding and the silicon carbide mold. The manufacturing method comprises the following steps: blank molding: performing mold dry pressing molding to obtain a silicon carbide mold sleeve and a mold core blank; mold sleeve blank processing: processing upper and lower planes, an outer circle, an exhaust hole and an inner hole; mold core blank processing: processing upper and lower planes, a mold core body outer circle and a step outer circle, and roughly machining an aspheric surface part; sintering at high temperature: sintering and densifying the mold sleeve blank and the mold core blank; mold sleeve finish machining: carrying out finish machining on upper and lower planes and inner and outer circles, and machining cylindricity; mold core half machining: preliminarily machining upper and lower planes, the mold core body outer circle and the step outer circle ; coating a mold core: depositing silicon carbide on an aspheric surface part; mold core finish machining: carrying out finish machining on the upper plane and the lower plane of the coated mold core, the mold core body outer circle and the step outer circle, and subjecting the aspheric surface part to finish machining; and mold core coating: coating the surface of the aspheric surface part, wherein the coating material is a material beneficial to glass demolding.
本申请属于碳化硅模具技术领域，具体涉及一种玻璃模造用碳化硅模具的制造方法及碳化硅模具，制造方法包括如下步骤：素胚成型：模具干压成型得到碳化硅模套和模仁素胚；模套素胚加工：加工上下平面、外圆、排气孔和内孔；模仁素胚加工：加工上下平面、模仁本体外圆和台阶外圆，并粗加工非球面部分；高温烧结：将模套素胚和模仁素胚烧结致密化；模套精加工：上下平面、内外圆精加工，并加工圆柱度；模仁半加工：上下平面、模仁本体外圆和台阶外圆初步加工；模仁镀层：非球面部分沉积碳化硅；模仁精加工：镀层后模仁的上下平面、模仁本体外圆和台阶外圆精加工，非球面部分精加工；模仁镀膜：非球面部分表面镀膜，镀膜材料为利于玻璃脱模的材料。
