压实式造型机的工作原理

压实式造型机的工作原理是利用气压或液压通过压头或模样对砂箱内的型砂施加压力来紧实型砂。其压强一般为0.25~0.4兆帕。这种造型机﹐使远离施压面的砂型紧实度差。20世纪50年代初出现了高压造型机﹐砂型平面上的压强在 0.7兆帕以上。高压造型化粪池模具 精密铸造 钢纤维 盐水注射机 风电基础模具 nsk轴承经销商 nsk轴承总代理 保定空调移机机的压头分为平压头﹑成形压头和多触头压头等几种结构形式。其中以高压多触头造型机应用最为广泛。
The working principle of compaction molding machine is to use air pressure or hydraulic pressure to apply pressure to the molding sand in the sand box through the indenter or pattern to compact the molding sand. The pressure is generally 0.25-0.4 MPa. This kind of molding machine makes the sand mold far away from the pressure surface have poor compactness. In the early 1950s, a high-pressure molding machine appeared, and the pressure on the sand mold plane was more than 0.7 MPa. The head of high pressure molding machine is divided into flat head, forming head and multi contact head. Among them, the high-voltage multi contact molding machine is the most widely used.
