摘要

肥皂盒在我们的生活中非常的普遍，几乎每家都要用到。市场上也有各种各样的肥皂盒，形状各异，有些是把肥皂盒做成水果造型，有些是动植物造型，来吸引顾客的目光，以引发人们的购买欲。此次设计的肥皂盒的结构较简单，但在设计时考虑其应用,还相应的做了些曲面,所以曲面结构较多,计算也就较多.在生活中,我们把肥皂放在盒上的时候，常常会因肥皂盒积水而使肥皂软化掉，这样就会降低肥皂的使用寿命。也有些肥皂盒在下盖底部打孔，使水容易流出，但是这类肥皂盒的缺点是，会因下面漏水，把房间里弄的湿湿的。此次设计的肥皂盒是在上盖上打孔，肥皂放在上盖上，这样水会沿孔斜度往下盖流，水积在下盖里，上下盖之间有一定的距离保证一定的时间里水不会满到上盖的肥皂上，积水手动倒掉即可，这样即保证了肥皂的利用率，又保证了房间的清洁。

优点是：结构简单，提高肥皂的使用寿命；缺点是:积在下盖的积水需人工手动倒出。此次设计是以上盖为主，下盖为辅。在上盖的设计中主要要解决以下几个问题：1、肥皂放在上盖上时，以点接触，设计六个椭圆突出,支撑肥皂，使肥皂和盒子之间以点接触；2、上盖上还要开一个槽，使水可以沿着曲面流人下盖；3、设计浇口时要注意上盖上表面的精度，不能在表面上留有印痕；4、在设计推出机构时要注意推杆放置的位置，放在下表面，不能影响上表面的表面精度；5、在开模时需保证塑件留在型腔上，用推杆顶出。设计中，辅以下盖的装配图。

Abstract

Soapbox in our lives is very common, almost every home to be used. On the market, there are a variety of soap box, shapes, some of the soap box made of fruit shape, some of the shapes of animals and plants, to attract customers attention to trigger people's desire to purchase. Relatively simple structure of the design of the soap box, but in consideration when designing their applications, but also do some surface, the surface structure more to calculate it more in life, we put the soap on the box time, often due to soapbox stagnant water leaving the soap to soften out, this will reduce the life of the soap. Also some soap box next to cover the bottom of the punch to make the water easy to outflow, but the drawback of this type of soapbox is leaking due to the following room neighborhood wet. Between the design of the soap box is covered in the drilling, soap placed on the cover so that the water flow down along the Taper cover, water plot next Gehry, the upper and lower cover a certain distance to ensure a certain time will not be full of water atop the soap, water can be drained manually, which is to ensure the soap utilization, while ensuring the cleanliness of the room.

The advantages are: simple structure, and improve the life of the soap; disadvantages are: plot the next cover of the water need to manually poured. The design is more than cover the main, supplemented by under cover. In the design of the superstructure is mainly to solve the following problems: a soap placed on the cover to the point contact, design six oval prominent support soap, to the point contact between the soap and boxes; Close the also a slot open, so that the water can cover along the surface inflow; 3, the design gate to cover the surface of the accuracy, prints can not be left on the surface;, design and market institutions attention to the push rod placed on the lower surface, can not affect the upper surface of the surface accuracy; need to ensure, in the mold plastic parts remain in the cavity and top out with his putter. Design, the following auxiliary cover assembly drawing.
