浮盖塑件的注塑工艺及模具设计
摘  要
本文是关于浮盖模具的设计，里面对浮盖做了正确的工艺分析，同时也对注塑成型技术的发展过程和选取的注塑材料（PP）了简单的介绍。设计的内容包括分型面的设计、浇注系统的设计、侧向抽芯机构的设计,以及模架和注塑机的选取和校核。考虑到生产效率，经济性和生产效率等相关因素，模具采用一模两腔的模具结构，由于型腔结构较为复杂，采用组合式结构。型芯采用整体式结构，便于加工且节省成本。为使加工方便同时满足塑件成型，采用侧浇口形式。此模具的结构较为复杂，应用到了斜导柱滑块侧向抽芯机构，它是本次设计的重点。然后根据浮盖的结构特点设计了模具的成型零部件（型芯、型腔、滑块），脱模、复位及导向机构。模具是材料成型加工中的工艺装备，它是利用其特定形状去复制成型或复制加工具有一定形状和尺寸的工具。。浮盖在日常生产中是大批量投入生产的，应尽量减少开，合模取塑件过程中的手工操作，本次设计中采用自动开、合模和顶出机构。

Floating cap Injection Mold Design

ABSTRACT

This is the floating cap Injection Mold Design, floating cap inside of a correct analysis of the technology They are also injection molding technology development process and the selection of the injection material (PP) has made a brief introduction. The design includes the sub-surface design, the gating system design, lateral pulling mechanism of the design, and the die-injection molding machine and the selection and check. Taking into account production efficiency,economy and efficiency,and other related factors,the die using a two-cavity mold structure.As the cavity structure is more complex,using the combination structure. Core adoption of a whole structure,and facilitate the processing cost savings.To facilitate processing to meet molding plastic parts,using the form side gate. Die of this structure is more complex, application of the bevel-slider lateral pulling mechanism, which is the current focus of the design. According floating cap  design of the structural characteristics of the die molding parts (core, cavity and slider), ejection, reduction and oriented institutions. Mold is the Material Processing Technology equipment, It is using its special shape to copy or reproduce molding process with a certain shape and dimensions of the tool. Floating cap in the day-to-day production of large quantities of inputs for production, we should minimize the open, mold plastic parts for the process of hand. The design of automatic opening, mold and head out of institutions.
