整理箱上盖的注塑模具设计-塑料注射模含NX三维、模流及10张CAD图+说明书

塑件三维内侧

基于CAD/CAM技术的整理箱上盖注塑模具设计
摘要
本次设计主要是根据指定的塑件产品进行建模，根据塑料制品的要求，设计出符合要求的塑件，参照一般塑件结构设计，画出塑件建模图纸，然后通过了解用途，分析工艺性、尺寸精度等，确定了选择ABS材料进行注塑生产，进行合理的模具结果的设计。
设计中的方案主要确定了塑件的分型面选择，确定好分型面后，根据塑件大小和结构特点进行型腔布局，本次设计采用了一模两腔的模腔数量，主要通过几种方案对比得到最佳布局方案，然后进行浇注系统的分型设计哦，选择合适的浇口和流道大小。完成浇注系统后，还需要设置冷却系统和顶出机构，冷却系统设计主要考虑的是冷却均匀，保证塑件成型周期满足要求，顶出系统需要满足塑件可以成功顶出，进行批量生产，不出现产品缺陷等，最终需要选择合适的模架大小等完成整个注塑模具的设计。并且对各种参数校核。进行各部件三维建模，和二维工程图得绘制，整理出计算过程和设计总结，完成整个设计。

Design of injection mold for top cover of packing case based on CAD / CAM Technology
Abstract
This design is mainly based on the specified plastic products for modeling, according to the requirements of plastic products, design the plastic parts that meet the requirements, refer to the general plastic structure design, draw the plastic modeling drawings, and then through understanding the purpose, analysis of technology, dimensional accuracy, etc., determine the selection of ABS materials for injection production, and design the reasonable mold results.
The first mock exam is mainly about the selection of the parting surface of the plastic parts. After the parting surface is determined, the layout of the cavity is made according to the size and structural characteristics of the plastic parts. The design adopts a number of two cavities with a single mold, and the best layout scheme is obtained through comparison of several schemes. Then, the design of the gating system is divided into the proper type, and the proper gate and runner size are selected. After the completion of the pouring system, the cooling system and ejection mechanism need to be set up. The cooling system design mainly considers the uniform cooling to ensure that the molding cycle of the plastic parts meets the requirements. The ejection system needs to meet the requirements that the plastic parts can be successfully ejected for mass production without product defects. Finally, the appropriate mold frame size needs to be selected to complete the design of the entire injection mold. And check all kinds of parameters. Carry out three-dimensional modeling of each component, draw two-dimensional engineering drawings, sort out the calculation process and design summary, and complete the whole design.
