摘要 本次的产品名称为KF235接线端子它是生活中常见的塑件塑料产品，拿到产品以后需要用UG进行三维建模，产品壁厚比较均匀，适合中大批量生产，然后再分析该产品的特性特征，它的用途、作用以及它的结构特征怎么做，然后结合它在生活的用途和性能、以及结合材料的特性确定该产品的材料为ABS(增强)。 分析完产品本身以后首先需确定该产品的分型面，这一步至关重要，通常采用产品最大端面处为分型面。然后再用UG测量出该产品的最大尺寸多少，结合实际确定出一模几腔满足实际加工要求，经过综合分析为一模四腔的型腔布局，布局规则和均匀，然后选择合适的模架即可。流道尽可能的设计在塑件中间，保证其良好的充填性，本次采用潜伏浇口。本次设计的产品难度和结构一般，就利用分型面自然排气，不用单独设计排气系统。再者，水道也要设计得均匀的冷却产品，不可离流道太近，再者就是水道和产品距离需要大于5mm。本次设计顶杆分布均匀顶出塑件，可以在塑件脱模之后的质量得到保证。设计完了以后就对模具进行参数校核，然后确定各个结构之间配合是否符合设计要求，对比，不符合要求的微作调整。然后检查完成以后就导出二维图在CAD里面进行标注，整理图档。 关键词：三维建模;模架；注塑模具设计；校核 Abstract The
name of this product is kf235 termi
nal block, which is a commo
n plastic product i
n our life. After getti
ng the product, we
need to use UG for three-dime
nsio
nal modeli
ng. The wall thick
ness of the product is relatively u
niform, which is suitable for medium a
nd large-scale productio
n. The
n we a
nalyze the characteristics of the product, its use, fu
nctio

nd its structural characteristics, a
nd the

ne its use a
nd performa
nce i
n our life, as well as the bo
ndi
ng materials The material of the product is ABS (rei
nforced). After a
nalyzi
ng the product itself, the first step is to determi
ne the parti
ng surface of the product, which is very importa
nt. Usually, the largest e
nd face of the product is used as the parti
ng surface. The
n the first mock exam is made the first mock exam of the product, a
nd the UG is used to measure the maximum size of the product. The cavity is calculated to be a four cavity mold with regular layout a
nd u
niform layout. The ru
n
ner should be desig
ned i
n the middle of the plastic part as far as possible to e
nsure its good filli
ng performa
nce. The late
nt gate is used this time. The difficulty a
nd structure of the product i
n this desig
n are ge
neral, so the parti
ng surface is used for
natural exhaust i
nstead of separate desig
n of exhaust system. Moreover, the water cha
n
nel should be desig
ned to eve
nly cool the product,
not too close to the flow cha
n
nel. Moreover, the dista
nce betwee
n the water cha
n
nel a
nd the product should be greater tha
n 5mm. I
n this desig
n, the ejector bars are eve
nly distributed to push out the plastic parts, which ca
n e
nsure the quality of the plastic parts after demouldi
ng. After the desig
n is completed, the parameters of the die are checked, a
