目前,厨卫行业市场前景广阔,市场规模巨大,未来3-5年仍然保持年均10%以上的增长速度,由于厨卫行业利润空间大,但行业品牌集中度低,尚未形成大规模的领导品牌,随着市场竞争的口益激烈,各大厨卫企业都面临着巨大的发展机遇。厨卫产品中,面盆飞边属于一大类产品,包括水槽、洗盆、沥水篮等,随着厨卫市场竞争的口趋激烈,面盆飞边落料产品的高端化趋势口益明显,特别是随着人们消费水平的提高,他们需要品质更为优异、更具时尚化、人性化的产品,因此,对面盆飞边落料的生产以及模具制造提出了更高的要求。
本文对首先冲压件的工艺分析,完成工艺方案的确定。然后对零件排样图的设计,完成材料利用率的计算。再进行冲裁工艺力的计算和冲裁模工作部分的设计计算,对选择冲压设备提供依据。最后对主要零部件的设计和标准件的选择,为本次设计模具的绘制和模具的成形提供依据。通过前面的设计方案画出模具各零件图和装配图。

At present, the kitchen industry market prospects are bright, the market size is huge, the next 3-5 years still maintain an average annual growth rate of more than 10%, due to kitchen and toilet industry profit margins, but the industry brand concentration is low, has not yet formed a large-scale leadership Brand, with the fierce competition in the market, the major kitchen and toilet enterprises are facing a huge opportunity for development. Kitchen and toilet products, the basin flash is a large class of products, including the sink, wash basin, drain basket, etc., with the kitchen and the market competition in the mouth of the intense, the edge of the basin flashing products, high-end trend of obvious benefits, especially With the improvement of people's consumption level, they need to be more excellent quality, more fashionable, user-friendly products, therefore, the side of the basin flash blanking production and mold manufacturing put forward higher requirements.
In this paper, the first stamping process analysis, to complete the process to determine the program. And then the design of the layout of the parts to complete the calculation of material utilization. And then the calculation of the punching process and punching die part of the design calculation, to provide the basis for the choice of stamping equipment. Finally, the design of the main parts and the choice of standard parts for the design of the mold design and mold to provide the basis for the formation. Through the previous design plan to draw the mold parts and assembly drawings.
