热水袋塞盖的注塑模具设计-塑料注射模含23张CAD图+说明书

塑件三维

中国的模具工业作为一个新型且独立的制造业，正处于快速发展阶段，未来模具工业发展前程极宽广。21世纪以来，各个行业都得到了十分高速的发展，在此之中，模具行业根据市场的实际情况以及各个商品的需求，迅速孕育而生并脱颖而出。本文重点陈诉的是热水袋塞盖的注塑模具设计。
本文设计的塑件为热水袋塞盖，要求结构简单，并且带有小孔和外螺纹，大批量的生产，所以生产时要研讨出成本最少的方案。塞盖涉及的精度不高，塑件外表可以有分型面痕迹。综上情况，该设计没有选用齿轮、齿条自动脱螺纹的构造，而是选用了斜导柱带动侧滑块使之注塑成型。此塞盖选用一模两腔三板式，规划了两个分型构造，进料用点浇口，顶管式的顶出装置，瓣合式的构造，并用斜导柱带动侧滑块分型。根据上边所陈诉的元素，设计的子详细方案在接下来文章有详细的说明和验证。
塞盖塑件是一模两腔且左右对称式结构，为了缩短周期，降低生产难度，选用四个一模一样的滑块组成该结构。这样设计使得模具构造简单，分布均匀，有益于加工。

Abstract
The molding trade of China is an independent and late-model manufacturing, it is in a fast developing stage very much,its development prospect is very vast.The future of the mold industry is very broad.Since twenty-first Century, all industries have developed at a very high speed,in this case, according to the actual situation of the market as well as the needs of various commodities,mould industry quickly nurtured and born, and stand out.This paper mainly introduces the design of injection mould for hot water bag cork.
In this paper, the design of plastic parts for the hot water bag cover. Because the demand requires structure is very simple, and plastics has small holes and external threads, and large quantities of plastic parts ,Therefore, we should consider reducing costs as much as possible during production.Plug has not high accuracy. The surface of the plastic part can be marked with parting surface. In a word to reduce the spend of the manufacture,the design does not use gear with the wheel, rack to break off shedding structure automatically.Instead, the oblique guide column is used to drive the side slider to make injection molding .This cover mold uses a mould and two cavity structure and three plate to get into material. Two types of parting structure, feed point gate, pipe jacking device and sandwich structure are designed ,the side guide block is driven by oblique guide column.According to the above report elements, the design scheme is illustrated and validated in detail in the next article.
The plastic plug is a mould and two cavity and symmetrical structure, in order to shorten the cycle, reduce the production difficulty, with four of the components of the structure of the slider as like as two peas.This design makes the mold simple structure, evenly distributed, use ful for processing.

Key words: Mold, Plastics piece , Point gate,Slanting guide post
