随着生产的发展压铸产品愈来愈多样化,产品结构愈来愈复杂.生产中遇到不少由滑块成形的深型腔及大平面,这种由滑块成形的深型腔及大平面在开模、滑块返回的过程中由于拔模力的作用,往往易造成滑块成形的大平面变形及深型腔处的脱模困难问题.通常解决的办法是增大滑块成形部位的拔模斜度及大量使用涂料.但是,实际生产中某些产品不允许有过大的拔模斜度,而大量使用涂料又易造成铸件的气孔、欠铸、表面花纹等缺陷.最近我厂采用滑块成形深型腔顶出机构,成功地解决了这一问题.
With the development of production more and more diversified die-casting products, product structure more and more complex.Production encounters many of the deep cavity formed by the slider and the large plane, the slider formed by the deep cavity and large Plane in the mold, the slider return process due to the role of draft force, often easy to cause large deformation of the slider forming and deep cavity at the demoulding problems. The usual solution is to increase the slider forming parts Of the draft and extensive use of paint.However, the actual production of certain products do not allow excessive draft angle, and the heavy use of paint and easy to cause the pores of the casting, casting, surface patterns and other defects recently I The factory uses the slider to form the deep cavity ejector mechanism, successfully solved this problem.
