1、洛阳理工学院毕业设计（论文） I 窗框异型材挤出机头设计 摘 要 塑料窗框 具有传统 窗框 难以比拟的优异性能，是国家建设部推广使用的节能、环保型产品。目前已广泛用于各种建筑工程中，其发展空间很大，前景十分看好。本文是关于窗框异型材挤出机头的设计 ，设计 主要 包含两部分内容， 一 是 80 型推拉框挤出 机头和定型模 的设计 ,二 是 窗框异型材原材料配方的设计 。 其中挤出机头模具设计是该设计的重要内容，也是设计的难点。挤出机头模具的设计主要包括机头各部件外形和尺寸的设计以及定型模的设计。定型模的设计 主 要包括定型模腔的设计和定型模长度的设计 。 原材料配方设计 主 要包括 PVC 树脂

2、型号、稳定剂、改性剂、润滑剂、着色剂、加工助剂和填充剂 等 的选取和分配比例 。 关键词： PVC-U， 塑料异型材 ， 窗 框 ， 机头 ， 定型模 洛阳理工学院毕业设计（论文） II Design of Extruder Head Mold of the Window Frame Profiles ABSTRACT Plastic window frames has excellent performance that traditional window frames difficult to compare. It is so energy-saving and environment

3、-friendly as to becoming the product that ministry of our construction promotes its use. For the present, plastic window frames has been widely used in all kinds of architectural engineering, it has a bright future. This article is about the design of sash profile extruder head. The design consists

4、mainly of two parts. The first part includes sliding frame of 80 type extruder head and the design of stock mould. The second part includes the design of sash profiles raw recipe. Wherein the extruder head design is the important part of the design, but also the difficulty of the design. The design

5、of the extruder die for the various components includes the shape and size of the head design and sizing die design. The design includes sizing die cavity shape length of the mold design and the design of the type. Formulation materials include the selection and allocation ratio of PVC resin model, stabilizers, modifiers, lubricants, colorant, processing aids and fillers and so on.
