摘  要

    近年，模具行業(yè)結(jié)構(gòu)調(diào)整和體制改革步伐加大，主要表現(xiàn)在：大型、精密、復(fù)雜、長壽命、中高檔模具及模具標(biāo)準(zhǔn)件發(fā)展速度高于一般模具產(chǎn)品；塑料模和壓鑄模比例增大；專業(yè)模具廠數(shù)量及其生產(chǎn)能力增加等。模具成型具有優(yōu)質(zhì)，高產(chǎn)，低消耗，低成本的特點。塑料工業(yè)又是世界上發(fā)展最快的工業(yè)之一。在日常生活中幾乎每天都使用塑料制品，這些產(chǎn)品的大部分可由注塑成型的方法生產(chǎn)。 本文主要介紹了門把手注射模具設(shè)計，論述了塑料成形的工藝以及注塑的過程，并對注塑機進行了一些簡單的介紹。門把手注塑模具設(shè)計的主要過程有：塑料制品的工藝性分析，型腔數(shù)目的確定，注塑機的選擇以及模具的結(jié)構(gòu)設(shè)計。模具的結(jié)構(gòu)設(shè)計包括：澆注系統(tǒng)的設(shè)計，成型零件設(shè)計，導(dǎo)向機構(gòu)設(shè)計，齒輪脫模機構(gòu)設(shè)計，冷卻機構(gòu)設(shè)計以及排氣系統(tǒng)設(shè)計。此次門把手的設(shè)計采用一模兩腔，對模具的各部分零件進行了設(shè)計與計算，同時對模具的工作原理和工作過程，以及模具的使用與保養(yǎng)也進行了說明。

Abstract

　　　

　　　In recent years, mould industry structure adjustment and reform, which is mainly manifested in pace increase: big, precision, complex, long life, high-grade mould and standard mould development faster than average mould products; Plastic mold and die casting die ratio increases; Professional production factory quantity, and increased ability, etc. With high quality, the high yielding molds, low consumption, low cost characteristic. Plastic industry is the world's fastest-growing major industrial one. In everyday life almost everyday use plastic products,  most of these products by injection molding method production. This paper mainly introduces the plastic injection molding process, as well as the process of injection molding machine also carried out a number of brief. The main injection mold design process are: process analysis of plastic products, to determine the number of cavity, the choice of injection molding machine, as well as the structural design of mold. The structural design of mold include: the design of gating system, forming part design, design-oriented, Demoulding design, cooling design and exhaust system design. This article is designed to mold a three-plate mold cavity. Food basket due to the special shape, the mold sets out through the top of the differential, the paper of the various parts of the mold parts to the design and calculation. In this paper, the working principle of the mold and the work process, as well as the use and maintenance of molds are also described. In this paper, detailed design and assembly process.


Keywords：Door handles ； Injection mold design ； Process analysis ；mechanism design
