技术领域 technical field
本发明涉及一种镶嵌式阀芯及其制造工艺。 The invention relates to an inlaid valve core and its manufacturing process.
背景技术 Background technique
原阀芯制作工艺包括：制造阀芯芯盒模具、阀芯外壳模具，所述二种模具均为覆模砂型；利用阀芯左芯盒模具以及阀芯右芯盒模具合型形成阀芯芯腔，此用于制作阀芯孔芯；利用阀芯左外壳模具以及阀芯右外壳模具合型生成左右阀芯外壳；将制备好的阀芯孔芯放入阀芯左外壳内，再合上右阀芯外壳合型形成阀芯型腔；合箱、浇注、后处理形成球墨铸铁材质阀芯成品。 The manufacturing process of the original valve core includes: manufacturing the core box mold of the valve core and the shell mold of the valve core, both of which are mold-covered sand molds; using the mold of the left core box of the valve core and the mold of the right core box of the valve core to form the core of the valve core Cavity, which is used to make the core of the valve core; use the mold of the left shell of the valve core and the mold of the right shell of the valve core to form the left and right shells of the valve core; put the prepared core of the valve core into the left shell of the valve core, and then close it The housing of the right spool is molded to form a spool cavity; the box is closed, poured, and post-processed to form a finished spool made of ductile iron.
此工艺直接制成的阀芯，阀芯上的阀芯滑槽一次浇注成形，生产效率较高，但由于直接浇注成形，滑槽精度差、表面粗糙，从而造成阀芯上下移动阻力增大及阀芯包胶时因阀芯两侧包胶厚度偏差，导致产品不合格。 The spool made directly by this process, the spool chute on the spool is formed by one-time casting, and the production efficiency is high. However, due to the direct casting, the chute has poor precision and rough surface, which causes the resistance of the spool to move up and down to increase. When the valve core is covered with rubber, the product is unqualified due to the deviation of the thickness of the rubber on both sides of the valve core.
