真空吸塑成型模具的设计包括了批量大小、成型设备、精度条件、几何形状设计、尺寸稳定性及表面质量等内容。
The design of vacuum suction moulds includes batch size, moulding
equipment, precision conditions, geometric design, dimensional stability
and surface quality.
1、批量的大小实验用,模具产量小时,可采用木材或树脂进行制造。但是,如果实验用模具是为了获得制品有关收缩、尺寸稳定性及循环时间等的数据时,应该使用单型腔模具来实验,且能保证其能在生产条件下运用。模具一般用石膏、铜、铝或铝-钢合金制造,很少用到铝-树脂。
1. For batch size experiments, if the output of the mould is small, it
can be manufactured with wood or resin. However, if the experimental die
is used to obtain the data of shrinkage, dimensional stability and
cycle time of the product, the single cavity die should be used for the
experiment, and it can be used under production conditions. Moulds are
usually made of gypsum, copper, aluminium or aluminium-steel alloys, and
Aluminium-Resin is seldom used.
2、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
检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 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。
2. In geometric design, dimensional stability and surface quality are
often considered comprehensively. For example, product design and
dimensional stability require the use of negative dies (concave dies),
but products with higher surface gloss require the use of positive dies
(punches), so that plastic parts orderers will take these two points
into account, so that products can be produced under optimal conditions.
Experience has proved that design that does not meet the actual
processing conditions is often a failure.
