Ceramic spring forming die

陶瓷弹簧成型模具

Abstract

This utility model discloses a ceramic spring mould which can greatly simplify process of the ceramic spring and is characterized in that: the utility model comprises a flexible internal model and two external models, wherein the flexible internal model is a hollow sealed cylindrical body, the outer wall of which is provided with internal model spiral grooves and the shapes of which fit the shape of the ceramic spring to be made; an internal model of the hollow sealed cylindrical body is provided with stomata; the two external models are two symmetric hemicyclic bodies which can form a circle with a diameter matching the external diameter of the flexible internal model; the inner wall of the two external models are provided with external model spiral grooves which match the internal model spiral grooves in the outer wall of the flexible internal model; in a place of the inner wall of one external model which is correspondent to the topmost external model spiral groove, a grouting groove is provided;, the bottom of the grounting groove is communicated with the topmost external model spiral groove, while the top perforates the top end of the external model. The utility model can ensure the blank density and shapes of the ceramic spring and improve quality of the ceramic spring.
本实用新型公开了可使陶瓷弹簧的生产工艺大为简化的陶瓷弹簧成型模具,其特征是它由柔性内模和两外模组成,柔性内模为一中空封闭柱状体,其外壁上设有与所要制作的陶瓷弹簧形状相吻合的内模螺旋凹槽,且中空封完备状体内模上设有气孔,两外模为对称的半圆环形体,它们合起后的总内径与柔性内模外径相吻合,且它们的内壁均设有与柔性内模外壁上内模螺旋凹槽相吻合的外模螺旋凹槽,且在一外模的内壁对应最上一道外模螺旋凹槽的位置向上开有注浆槽,该注浆槽下端与最上一道外模螺旋凹槽相连通,其上端通出外模的上端面。有利于保证陶瓷弹簧的坯体密度和形状,提高陶瓷弹簧的制造质量。
