Porous ceramic sandwich injection molding method and device
The invention relates to a porous ceramic sandwich injection molding method, and relates to the technical field of injection molding. A porous ceramic sandwich injection molding method comprises the following steps that a first feed and a second feed are injected into a mold cavity, the starting time of injection molding of the second feed is later than the starting time of injection molding of the first feed, then cooling and demolding are conducted, and a porous ceramic green body is obtained; the first feed comprises 35 to 50 weight percent of quartz glass, 5 to 10 weight percent of a multiphase additive, 20 to 40 weight percent of a pore forming agent, 5 to 15 weight percent of a sintering aid and 5 to 15 weight percent of a binder; the second feed comprises 55 to 70 wt% of quartz glass, 4 to 8 wt% of a multiphase additive, 5 to 15 wt% of a pore forming agent, 5 to 15 wt% of a sintering aid and 5 to 15 wt% of a binder. The porous ceramic with different inner and outer layer structures is obtained through a sandwich injection molding method, the relationship between leakage prevention and the use taste of consumers is balanced, the porous ceramic has good leakage prevention, the use taste of the consumers is improved when the porous ceramic is used as a ceramic atomization core, and the use feeling of the consumers is improved.
本发明涉及一种多孔陶瓷夹心注射成型方法，涉及注塑成型技术领域。一种多孔陶瓷夹心注射成型方法，包含以下步骤：将第一喂料和第二喂料注塑进模具腔，所述第二喂料注塑的开始时间晚于第一喂料注塑的开始时间，后经冷却脱模，得到多孔陶瓷生坯；所述第一喂料包含，石英玻璃35‑50wt％，复相添加剂5‑10wt％，造孔剂20‑40wt％，助烧剂5‑15wt％，粘结剂5‑15wt％；所述第二喂料包含，石英玻璃55‑70wt％，复相添加剂4‑8wt％，造孔剂5‑15wt％，助烧剂5‑15wt％，粘结剂5‑15wt％。本发明通过夹心注射成型方法得到具有不同内外层结构的多孔陶瓷，平衡防泄漏性和消费者使用口感两者的关系，具有较好的防泄漏性，提高其作为陶瓷雾化芯应用时消费者的使用口感，提高消费者的使用感受。
