模具设计要点
模具设计要点
Key Points of Die Design
1、模具材料的选择:因为水泥件在成型时,模具在强烈震动,水泥会对模具产生很大的摩擦。因此,该模具必须要有很好的耐磨性和较高的硬度,根据这些条件选择使用聚丙烯颗粒或者强度更好的ABS材料。

1. Selection of die material: Because when the cement parts are forming, the die is shaking strongly, and the cement will cause great friction to the die. Therefore, the die must have good wear resistance guanjian.37ix.com.cnmojuggb.37ix.com.cnbaozhuangmo.37ix.com.cnmojujg.37ix.com.cnmojublg.37ix.c

2、根据生产厂家要求的产品密度及生产原料的主要性能及配比,确定该产品的压缩率为25%
2. According to the density of the product required by the manufacturer and the main properties and proportions of the raw materials, the compression rate of the product is determined to be 25%.
3、在工艺结构.上模腔和吊梁之间采用独特的非焊接式结构,使模腔更富有弹性,抗震性和疲劳能力大大加强。
3. The unique non-welded structure between the upper die cavity and the suspension beam makes the die cavity more elastic, and the aseismic and fatigue capabilities are greatly enhanced.
4、模腔、型芯与上压板之间配作加工,保证周边间隙为0.6~1mm,以确保产品的外形尺寸、质量的稳定。
4. Machining the die cavity, core and upper pressure plate to ensure the surrounding clearance of 0.6-1 mm, so as to ensure the stability of the product's shape, size and quality.
5、因该产品各尺寸无精度要求,同时空心部位已设计有较大的脱模斜度,因此设计该产品的型芯、型腔时所有尺寸都采用名义尺寸。
5. Because there is no precision requirement for each dimension of the product, and the hollow part has been designed with a larger demoulding slope, all dimensions of the core and cavity of the product are nominal.
