中文摘要: |
注塑机合模部件的双曲肘机构中的大销轴和轴套容易磨损,甚至互相啮合损坏,从而影响合模部件的使用寿命。
为此设计了新型注塑机大销轴旋转机构,即把大销轴由“死固定”改为“活固定”,允许大销轴相对每个轴套360。自由旋
转。采用这种新型机构,大大减少了大销轴和轴套的磨损,以及互相啮合的可能性,延长了合模部件的使用寿命。 |
英文摘要: |
The most easily damaged parts are the bigger axis pin and the axle sleeve in the double toggle mechanism of an
assembly part of the injection molding machine. The abrasion of bigger axis pin and the axle sleeve. or even the mutual
meshing damage may cause harm to the service life of mold-closing parts. In order to solve the above-mentioned issues.
a new rotational structure of bigger axis pin in an injection molding machine was designed. By changing the
" inextricable" fixation method to a " flexible" one that allowed the bigger axis pin to be rotated (0-360 degree) freely
around each corresponding axle sleeve. the abrasion of bigger axis pin and the axle sleeve and the mutual meshing
possibility could be greatly reduced, and a longer service life of the mold-closing parts was achieved. |
