正确地确定塑料护坡模具成型零件的尺寸:成型零件是确定制件形状、尺寸和表面质量的直接因素,关系甚大,需特别注意。计算成型零件尺寸时,一般可采用平均收缩率法。对精度角高并需控制修模余量的制件,可按公差带法计算,对于大型精密制件,最好能用类比法,实测塑件几何形状在不同方向上的收缩率进行计算,以弥补理论上难以考虑的某些因素的影响。
It is necessary to determine the shape, size and surface quality of the
molded parts, and the relationship is very important. Generally, the
average shrinkage method can be used when calculating the dimensions of
forming parts. For high precision Angle and repair the mold spare parts,
which shall be controlled according to tolerance zone method to
calculate, for large precision parts, had better use analogy method, the
measured parts geometry calculation is made of shrinkage in different
directions, to make up for in theory is difficult to consider the
influence of some factors.
设计的塑料护坡模具应当制造方便:设计塑料护坡模具时,尽量做到使设计的模具制造容易、造价便宜。特别哪些比较复杂的成型零件,必须考虑是采用一般的机械加工方法加工还是采用特殊的加工方法加工。若采用特殊的加工方法,那么加工之后怎样进行组装,类似问题在设计塑料护坡模具时均应考虑和解决,同事还应考虑到试模以后的修模,要留有足够的修模余量。
The design of plastic slope mould should be convenient to make: when
designing plastic slope mould, make it easy and cheap to make the mould
designed. In particular, which are more complex forming parts, it is
necessary to consider whether the general mechanical processing method
is used for processing or the processing of special machining methods.
If the use of special processing methods, the processing after
assembling, a similar problem in slope protection design plastic mold
should be considered and solved, colleagues also should take into
account the test after repair the mold, should have enough repair
allowance.
充分考虑塑件设计特色,尽量减少后加工:尽量用模具成型出符合塑件设计特点的制件,包括孔、槽、凸、凹等部分,较少浇口、溢边的尺寸,避免不必要的后加工。但应将护坡模具设计与制造的可行性与经济性综合考虑。防止片面性。
After fully considering the plastic parts design features, to minimize
processing: use molding parts out of accord with the characteristics of
plastic parts design, including hole, slot, convex and concave part,
less the size of the gate, overflow, avoid unnecessary after processing.
However, the design and manufacturing feasibility and economy of the
slope mould should be considered. Prevent one-sided.
设计的塑料护坡模具应当效率高、安全可靠:这一要求涉及到塑料护坡模具设计的许多方面,如浇注系统需充模块、闭模块,温调系统效果好,脱模机构灵活可靠,自动化程度高。
Slope protection design of plastic mold should be of high efficiency,
safe and reliable: the request involves many aspects of slope protection
plastic mould design, such as pouring system need to charge module, the
module closed, temperature regulating system effect is good, demoulding
mechanism is flexible and reliable, high degree of automation.
