接水盒注射成型工艺及模具设计
 
摘 要： 此设计题目为一个冰箱的接水盒，此塑件在技术要求方面要求不高，所以模具设计的精度也不需要太高。通过对不同设计方案的对比。最终确定设计方案为：（1）分型面选在零件高度为5㎜的地方。（2）模具设计为一模两腔式的制件布局。（3）模具浇口采直浇口，使模具容易分型。（4）模具的推件机构采用推杆推出。（5）模具的型芯和型腔都设计为整体式。
由于设计能力有限，设计过程中有还存有许多不足之处：模具的选材、材料的利用率……等，这些因素都影响模具整体的经济性。此方案不一定为最佳方案，但经过精确的计算和校核，此套模具能够加工出所需要的合格制件，再加上制件的精度要求不是很高，所以此模具可以投入生产使用。

      DESIGN PROCESS AND MOID INJECTION MOLDING
WATER BOX
 
 ABSTRACT：This design topic is a box of collected water. The plastics are not requested very strict in technique .Based on different projects I choose the later project: First, the parting surface is choose at a high degree of 5mm .Second,there are two mold cavities in this mold .Third,the gate of mold choose pin-point gate ,for this the mold should have to increase one parting surface .Forth,the ejector equipments of the mold is choose ejector plate.
Because my ability of design is limited ,the design still contains many places to be corrected ,such as choose the material of the mold 、the utilization of the material ……these factors will influence the economic of the mold .So this project is mot the best one,but after calculation and check figures accurately.This mold can make out qualified products and be used in factory.
