注塑模具抛光加工时的注意事项!

来源:http://www.sdlqmj.com 日期:2019-09-28 发布人:admin 浏览次数:
注塑模具抛光有两个目的,一个是增加模具的光洁度,使模具出的产品的表面光洁,漂亮,美观,另一个是可以模具很容易脱模,使塑料不被粘在模具上而脱不下来。今天山东模具制造厂家就给大家讲一讲在进行注塑模具抛光加工时的一些注意事项,希望对大家有所帮助!
Injection mould polishing has two purposes. One is to increase the smoothness of the mould, so that the surface of the product produced by the mould is bright, beautiful and beautiful. The other is that the mould can be easily demoulded, so that the plastic can not be glued to the mould and can not be removed. Today, Shandong Mould Manufacturer will tell you about some matters needing attention in polishing injection moulds. I hope it will be helpful to you all! 
(1)部分工件可能有多件组拼在一起研光,要先分别研单个工件的粗纹或火花纹,后将所有注塑加工工件拼齐研至平滑。
(1) Parts of the workpiece may be polished by a combination of several parts. The rough or spark patterns of a single workpiece should be polished separately, and then all the injection-moulded workpieces should be polished to a smooth level.
(2)研粗纹时要按先难后易的顺序进行,特别一些难研的死角,较深底部要先研。
(2) When grinding rough lines, it should be done in the order of difficulty before ease. Especially for some dead corners which are difficult to grind, the deeper bottom should be studied first.
(3)为防止注意模具工件研出倒扣或有一些贴合面需保护的情况,可用锯片粘贴或用砂纸贴在边上,这样可得到理想的保护效果。
(3) In order to prevent the upside-down of the die workpiece or the need to protect some veneer, the saw blade can be used to paste or sandpaper can be used to paste on the edge, so that the ideal protection effect can be obtained.
(4)大平面或侧平面的工件,用油石研去粗纹后再用平直的钢片做透光检测,检查是否有不平或倒扣的不良情况出现,如有倒扣则会导致制件脱模困难或制件拉伤。

(4) For workpieces with large or side planes, the roughness is removed by grinding with oil stone and then the flat steel sheet is used for light transmission inspection to check whether there are any unfair or upside-down bad conditions. If there is upside-down, it will lead to difficult demoulding or parts pulling.
(5)如果工件的平面用铜片或竹片压着砂纸抛光,砂纸不应大过工具面积,否则会研到不应研的地方。
(5) If the surface of the workpiece is polished with sandpaper pressed with copper or bamboo sheets, the sandpaper should not be larger than the tool area, otherwise it will be developed where it should not be studied.
(6)研模具平面用前后拉动,拖动油石的柄尽量放平,不要超出25°,因斜度太大,力由上向下冲,易导致研出很多粗纹在工件上。
(6) Pull the surface of the grinding die back and forth, and pull the handle of the oil stone as flat as possible. Do not exceed 25 degrees. Because the slope is too large, the force is pushed up and down, which easily leads to a lot of coarse grain on the workpiece.
(7)当一新模腔开始加工时,应先检查工件表面,用煤油清洗干净表面,使油石面不会粘上污物导致失去切削的功能。
(7) When a new die cavity begins to be processed, the workpiece surface should be inspected and cleaned with kerosene so that the oil-stone surface will not stick to the dirt and lose the cutting function.
(8)研磨的工具形状应跟模具的表面形状接近一致,这样才能确保工件不被研变形。
(8) The shape of the grinding tool should be close to the surface shape of the die, so as to ensure that the workpiece is not abraded and deformed.
