模具成型需要注意的几点因素 There are several factors that need to be noted for mold forming 　　我国塑料护坡模具行业这几年来的总体发展水平良好,企业加工水平得到很大提高,出口创汇能力大大增强,既在国内市场抵抗住境外厂商的挤压,又在国际市场上表现出了较强的竞争力,这样的情况下,想要拥有这样的竞争力,我们还需要注意模具的质量,今天我们就给大家介绍一下U型槽模具成型的几点影响因素。 Slope protection mould industry in China over the past few years the good overall development level and enterprise level of processing is greatly improved, the capacity to earn foreign exchange through export increases greatly, both in the domestic market to resist foreign manufacturers of extrusion, and shown strong competitiveness in the international market, in this case, want to have such a competitive, we also need to pay attention to the quality of the mould, today we will introduce you to u-shaped slot mold forming several influencing factors. 　　模具的修饰对模具的销售好坏也有一定的影响,所以在修模时要注意对模具的修饰。如果使用机械式水平锯锯掉塑件的夹持边,在高度方向上,至少要有6~8mm的余量。其他的修整工作,如磨削、激光切削或射流,也必须留有余量。还需要注意的是刀口模切割线间的间隙最小,冲孔模修整时的分布宽度也很小。 The modification of the mould also has a certain effect on the sale of the mould, so pay attention to the modification of the mould when repairing the mold. If you use mechanical horizontal saws to cut off the side of the plastic, at least 6 to 8mm in the height direction. Other modifications, such as grinding, laser cutting or jet flow, must also be left over. It is also important to note that the gap between the cutting lines of the blade is the smallest, and the width of the punching die is very small. 　　收缩量是在制造吸塑成型的国家电力模具时一定要考虑到的因素。如果不能清楚地知道塑料的收缩率,则必须取样或用相似形状的模具通过试验来得到。不过你还要注意,通过这种方法只能得到收缩率,不能得到变形尺寸。 The shrinkage is a factor that must be taken into account when making the electric molds of the country that are moulded. If you do not know the shrinkage of plastic, you must sample or use a similar shaped mold to get it. But you also have to pay attention to the fact that you can only get shrinkage in this way, and you can't get the size of the deformation.
