毕业设计（论文） 说明书 设计题目：花盆注射模 专业 机械设计制造及其自动化 摘要 近些年来，在我国,模具工业的发展十分的快速。其中尤其是塑料注塑模的制品，随着模具制造业的发展，热流道技术也得到了十分广泛的应用。它具有质料来源广,价格对比下惠而不费,通性出色等表征。它在电脑、手机、汽车、电机、制造中具有的作用 把塑料原料放入料筒中加热熔化是注射成形的方法，采用一些加压工具，比如柱塞或者螺杆等等，使熔化的塑料经过喷嘴在较高压力的推动下注入模具的型腔中，经过冷却以及凝固等阶段，然后脱模，我们想要的塑料制品就诞生了。 我的毕业设计题目是花盆的注塑模，塑料花盆具有份量轻、色泽和图案丰饶、耐老化、强度较高、打造方便、价钱便宜等长处，完全可以取而代之陶土花盆、也是花盆毫无疑问的发展方向。 本文讨论了塑料花盆注塑模的设计规划过程，介绍了花盆注射模成型工艺，以及注射模具的结构和工作的原理。规定了分型面，浇口结构，顶出机构，选取了注射机，筹划了零件大小，归因于该产品企划为大批量推出，就此模具要有相当高注塑速率，来保证成本加盟。出于塑件工艺性能要求，注塑模中必须要有负责冷却的东西，在我的模具设计中也进行了统筹。 关键词: 热流道; 注射模; 花盆; 模具设计; Abstract In recent years,the rapid development of mold industry in china, especially in the plastic injection molding products,with the development of mold manufacturing ,hot runner technology has also been very wide range of applications,It has a wide source of raw materials ,relatively the low prices ,excellent performance characteristics ,It has a very important role in the manufacture of computers,automotive electrical ,household products , injection is the primary means of forming thermoplastic,therefore its widely used. Method of injection molding is the plastic material into the melted barrel,with a plunger or screw as a heating tool to melt at high pressure through the muzzle into the mold cavity after cooling and sdification stages of heating , Out from the mold ,a plastic products we want. My praduaction design topic is a pot of injection mold ,plastic flower pot has the advantages of light weight rich color patterns ,aging resistance high strength convenient manufacture and low price ,Is the ideal substitute of clay pots ,pots is the inevitable direction of development. The design process of the injection mould for the plastic flower pots are discussed in the paper ,the flower pot injection molding process and injection mold structure and working principle of determine the type face ,gate structure ejection mechanism .choice of injection molding machine ,design the part size . Because the product for mass production .S
