造型是铸造生产中的一个重要环节。尤其手工操作的长件、薄件类铸件质量得不到保证,且劳动强度大,工作效率低。经改造成功的四缸震式造型机则是采用多缸气动与机械联动微振。适宜于制造细,长类纺织机械铸件。通过几年来生产实践证明:提高工作效率5倍,并保证了铸件质量。效益显著,受到中小型纺机厂铸造车间改 Modeling is an important part of casting production. In particular, the quality of long-manufactured and thin-piece castings cannot be guaranteed, and the labor intensity and work efficiency are low. The rebuilt four-cylinder shock-type molding machine uses multi-cylinder pneumatic and mechanical linkage micro-vibration. It is suitable for producing fine and long textile machinery castings. Through several years of production practice has proved: to improve work efficiency five times, and to ensure the quality of castings. Significant benefits, changed by the small and medium-sized textile machinery foundry
