介绍球墨铸铁盖板模具的设计

来源:http://www.kpp647.com添加时间:2016-09-23 16:29:09

一、塑件表面,就成型材料能够包住的范围而言,塑件可见面的表面结构应在与模具接触处成型。如果可能的话,塑件的光洁面不要与模具表面接触。就像采用阴模制造浴盆和洗衣盆的情况。

On the surface of the plastic part, the forming material can cover the range, the plastic part can meet the surface structure should be in contact with the mold. If possible, the plastic parts of the light cleansing do not contact with the mold surface. As the female mold manufacturing tub and the washing basin.

二、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。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,这些都是要注意的。

Two, modified, if the use of mechanical level plastic clamping saw sawed off the edge, in the height direction, there should be at least 6 ~ 8mm margin. Other finishing works, such as grinding, laser cutting, or jet, must be left with a margin. The gap between the minimum cutting edge cutting, trimming punching die when the distribution width is small, these are to be noticed.

三、几何形状设计,设计时,经常要综合考虑尺寸稳定性及表面质量。例如,制品设计和尺寸稳定性要求采用阴模(凹模),但是表面要求光泽度较高的制品却要求使用阳模(凸模),这样一来,塑件订购方会综合考虑到这两点,以使制品能在最佳条件下进行生产。经验证明,不符合实际加工条件的设计往往是失败的。

Three, geometry design, design, often to consider the size stability and surface quality。 For example, product design and dimensional stability requirements by die (die), but the surface products require a high gloss mold is required (punch), so that the plastic parts of the ordering party will consider these two points, so that the products can be produced under optimal conditions。 Experience has proved that the design does not conform to the actual processing conditions are often the failure of。

四、尺寸稳定,在成型过程中,塑件与模具接触的面要比离开模具部分的尺寸稳定性更好。如果日后由于材料刚度的需要要求改变材料厚度,可能导致要将阳模转换为阴模。塑件的尺寸公差不能低于收缩率的10%。

Four, the size is stable, in the process of forming, plastic parts and mold contact surface than to leave the mold part of the dimensional stability is better. If the day after due to the stiffness of the material required to change the material thickness, may lead to male into female die. The dimensional tolerance of the plastic part can not be less than 10% of the shrinkage rate.
