一种带有出料端辅助加热的陶瓷压铸机吸料泵
本专利技术属于陶瓷生产
,具体为一种带有出料端辅助加热的陶瓷压铸机吸料泵。
技术介绍
热压铸成型是陶瓷生产应用较为广泛的一种成型工艺,其基本原理是利用石蜡受热熔化和遇冷凝固的特点,将无可塑性的瘠性陶瓷粉料与热石蜡液均匀混合形成可流动的浆料,在一定压力下注入金属模具中成型,冷却待蜡浆凝固后脱模取出成型好的坯体。坯体经适当修整,埋入吸附剂中加热进行脱蜡处理,然后再脱蜡坯体烧结成最终制品。热压铸成型现已广泛应用于制造中小尺寸,形状复杂,精度要求较高的工业陶瓷产品,其设备投资小,生产规模可大可小,比较灵活。在压铸成型时,原料为半凝固状态,通常采用传统的压力泵,将原料泵入到模型腔内。受泵压的影响,被注入的原料可能在压力作用下产生气泡,使产品也产生气泡,影响压铸效果;同时,在泵腔内的原料出料时容易粘附在内壁上,是的出料缓慢甚至堵料。
