济南模具加工需要注意的几点事项

济南模具加工是塑料加工工业中和塑料成型机配套,赋予塑料制品以完整构型和精确尺寸的工具。由于塑料品种和加工方法繁多,塑料成型机和塑料制品的结构又繁简不一,所以济南模具加工的种类和结构也是多种多样的。那么,我们在设计济南模具加工时,都需要注意哪些要点呢?Ji'nan mold processing is the plastic processing industry and plastic molding machine, plastic products to complete configuration and precise size tools. Because of the plastic varieties and processing methods of various plastic molding machine and plastic product structure is simplified, so Ji'nan mold type and structure is various. So, we in the design of Ji'nan mold processing, need to pay attention to what points?

1.开模方向。济南塑料模具的开模方向确定后,可选择适当的分型线,避免开模方向存在倒扣,以改善外观及性能。济南塑料模具的开模方向确定后,产品的加强筋、卡扣、凸起等结构尽可能设计成与开模方向一致,以避免抽芯减少拼缝线,延长模具寿命。Opening direction. Ji'nan plastic mold after the mold direction is determined, you can choose the appropriate parting line, to avoid the opening direction of the existing button to improve the appearance and performance. Ji'nan plastic mold parting direction, product rib, buckle, convex structure as much as possible consistent with the direction of mold design, in order to avoid pulling reduce joint line, prolongs the service life of the mould.

2.产品壁厚。济南模具加工的壁厚不均会引起气孔和熔接痕。济南塑料模具的壁厚不均会引起塑胶产品表面缩水。各种塑料均有一定的壁厚范围,一般0.5~4mm,当壁厚超过4mm时,将引起冷却时间过长,产生缩印等问题,应考虑改变产品结构。Product wall thickness. The uneven thickness of the die in Ji'nan will cause the pores and the weld marks. The uneven thickness of plastic mold in Ji'nan will cause the shrink of plastic products. All kinds of plastic has a certain thickness range of 0.5~4mm, when the wall thickness is more than 4mm, will cause the cooling time is too long, which reduce and other issues, should consider changing the product structure.

3.扣位。将济南模具加工的扣位装置设计成多个扣位同时共用,使整体的装置不会因为个别扣位的损坏而不能运作,从而增加其使用寿命,再是多考滤加圆角,增加强度。济南塑料模具的扣位相关尺寸的公差要求十分严谨,倒扣位置过多容易形成扣位损坏;相反,倒扣位置过少则装配位置难於控制或组合部份出现过松的现象。解决办法是要预留改模容易加胶的方式来实现。Buckle position. Ji'nan mold locking device design into a plurality of buckling and sharing, so that the overall device will not buckle because individual bit damaged and not operation, thereby increasing its service life, and is admitted to filter radius, increase strength. Ji'nan plastic mold buckle a size tolerance requirements are very strict, inverted position too easy to form buckling damage; on the contrary, the inverted position is too difficult to control the assembly position or combination part appeared loose phenomenon. The solution is to modify the mold to be easy to add glue to achieve.

4.脱模斜度。济南模具加工厂家认为,适当的脱模斜度可避免产品拉毛(拉花)。光滑表面的脱模斜度应该小于0.5度,细皮纹(砂面)表面大于1度,粗皮纹表面大于1.5度。适当的脱模斜度可避免产品顶伤,如顶白、顶变形、顶破。深腔结构产品设计时外表面斜度尽量要求大于内表面斜度,以保证注塑时模具型芯不偏位,得到均匀的产品壁厚,并保证产品开口部位的材料强度。Stripping slope. Ji'nan mold processing factory, draft the appropriate products to avoid picking (Garland). The smooth surface should be less than 0.5 degrees, and the fine grain (sand) surface is more than 1 degrees, and the coarse grain surface is more than 1.5 degrees. Appropriate stripping slope can avoid the product top injury, such as top white, top deformation, top broken. In the design of the deep cavity structure, the external surface slope should be greater than the inner surface slope, so as to ensure that the die core is not biased, and the uniform product thickness is obtained.
