  毕业设计 茶杯塑件塑料注射模具设计 共56页,18604字 附工艺卡、零件图、装配图
   摘 要
   随着社会的发展,人们的生活水平不断得到提高,人们的生活观念正在发生巨大的变化,由原来的物质享受逐渐转变为精神方面的享受,在此之中,喝茶,品茶,评茶已经在社会上广泛流传,特别对老年人来说,对此道的认识尤为深刻。
   饮茶不但是传统饮食文化,同时,由于茶中含有多种抗氧化物质与抗氧化营养素, 对于消除自由基有一定的效果。因此喝茶也有助防老,具养生保健功能,每天喝三两杯茶可起到防老的作用。茶叶中含有多种维生素和氨基酸,喝茶对于清油解腻,增强神经兴奋以及消食利尿也具有一定的作用。
   常言道,美食还须美器配。喝茶也须有精美的茶具。茶杯就是人们喜欢的一种,茶杯的种类、大小应有尽有。喝不同的茶用不同的茶杯。近年来更流行边喝茶边闻茶香的闻香杯。根据茶壶的形状、色择,选择适当的茶杯,搭配起来也颇具美感。为便于欣赏茶汤颜色,及容易清洗,杯内面最好上釉,而且是白色或浅色。对杯子的要求,最好能做到“握”、“拿”舒服,“就口”舒适,“入口”顺畅。
   本次设计的茶杯为塑料产品,结构简单,尺寸适中,属薄壁壳体塑件,本产品除了可以当茶具外,用作刷牙杯子也是不错的选择。在当今社会,刷牙基本已成为人们每天必不可少的组成部分,对盛牙膏,牙刷的工具以杯子为主,人们在此方面一般不是很讲究,大部分以塑料杯子为主,就像我所设计的杯子就是人们喜欢的一种。
   本产品由于外形尺寸不是很大,考虑到生产的效率及产品的成本问题,最好用一模多穴,注塑机尽量选用注塑量比较大的。注塑机选用比较常用的 G54-S200/400型螺杆式注射机,考虑到本注塑机的最大注塑量及所设计塑件的 体积及投影面积,经判定适合用一模四穴(具体内容见后面本塑件型腔数目和分 布的计算),又本塑件侧向没有孔和槽,模具不需要设计侧分型与抽芯机构。但 由于塑件高度较高,为了节省浇道凝料,决定用双分型面注塑模。由于茶杯对外观要求比较严,不允许有推出痕迹,推出机构决定用推板推出。
   结果表明:本次设计无论是在注塑机的选用上,还是在模架,每次分模的数量及推出机构的设计上,都采用了比较合理的选择。我相信,以此模具生产的产品一定能够达到以最低的投入,达到最高的效益的效果。

   Abstract
   With the development of society, the people’s living standards have continued to improve, people’s life concept is undergoing tremendous changes, from the enjoyment the commentary widespread in the community, especially the older people, understanding this, and especially profound.
   Tea is not only the traditional food culture, at the same time ,because tea contains a variety of antioxidants and antioxidant nutrients, the elimination of free radicals have some effect. Therefore tea will also help to old age, a health care function, the three drank two glasses of tea every day can play the role of old age. Tea contains a variety of vitamins and amino acids, tea tired of the Qingyou, enhance nerve excitability and Xiaoshi diuretic but also has a certain role.
   As the saying goes, but also the United States for food distribution. Tea should also have a fine tea. People like teacups is a kind of the type of cup, the size of everything. Drink different with different cup of tea. In recent years more and more popular side of the tea-Wen Wen-Cha-xiang Cup. According to the teapot shape, colors election, the selection of appropriate cup, with up are also full of beauty. In order to facilitate the appreciation of tea color, and easy to clean, the best glazing glass inside, and is white or light-coloured. On the request of the cup, would be best to "hold", "using" uncomfortable, "I" comfort, "Entrance" smooth.
   The design of the cup for plastic products, simple structure and modest size, is a thin-walled plastic shell of this product in addition to the tea, cups used for brushing is a good choice. In today’s society, people brush their teeth every day has become a basic essential component of the Super toothpaste, toothbrush tools to the main cup, people in this area generally is not very particular about, most consisting mainly of plastic cups, like I designed the cup is that the people have a favorite.
   This product is not great because of Dimensions, taking into account the efficiency of production and the cost of products, it is best to use a multi-point mode, the injection molding machine to use than the larger injection. Injection Molding Machine G54-S200/400 use the more common type screw injection molding machine, taking into account the largest injection molding machine and the design of injection molding plastic parts and the size of the projected area, as determined suitable for a four-point (see details Plastic Parts cavity behind the number and distribution of the calculation), and the plastic parts lateral groove and had no holes, mold design does not require side typing and core-pulling mechanism. However, a high degree of higher plastic parts, in order to save runner condensate expected, decided to use the double-surface injection mold. Because of the cup relatively strict appearance requirements, does not allow any launch marks, the agency decided to launch push plates introduced.
   The results show that: the design of both in the selection and injection molding machine, or in the mold base, the amount of each sub-model and the introduction of the design, use a more reasonable choice. I believe that this mold products will be able to reach a minimum investment, achieve the highest efficiency results.
