生产中，经常会有遇到各种各样的问题，这其中产品毛边的问题就是非常常见，同时也是比较难处理的问题点之一，接下来我们一起来看下涌永硅橡胶 20 年工厂车间老师傅给大家分析下影响产品毛边的有哪几大因素。 In the production of rubber products , there are often encountered various problems. Among them, the problem of burrs is very common, and it is also one of the more difficult problems. Next, let's take a look at Yongyong silicone rubber. In the past 20 years, the master of the factory workshop gave you an analysis of the major factors affecting the burr of the product.
出现在模具分型线上，也就是合模线上，如果配模的时候，上下模配的不是很好，间隙过大，生产的时候就会导致产品毛边变厚或变大，另外因为毛边是靠模具本身自拆沟，来实现毛边与产品的分离。 The first is the mold. The mold is called the industrial mother. The quality of the mold directly determines the quality of the product. The burrs of rubber products often appear on the mold parting line, that is, the mold clamping line. It is not very good, the gap is too large, and the burr of the product will become thicker or larger during production. In addition, the burr is separated from the product by the mold itself. Therefore, the design of the self-demolition of the mold is also one of the key factors affecting the burr of the product. Otherwise, the burr will be jagged after being separated from the product.
165-185 摄氏度之间，特殊情况基本也不会差异太大。 The second point is that the reasonable setting of molding parameters will also affect the burr of the product. It is necessary to set the appropriate molding temperature according to different rubber materials, which is generally set between 165-185 degrees Celsius, and there will be basically no difference in special circumstances. It's too big. In addition, a reasonable clamping pressure must be set according to the size of the mold.
Secondly, some rubber products can't tear off the burrs immediately after molding. After the products are sufficiently cooled, the burrs should be removed. There are also burrs that need to be removed when the product is still hot. This must be determined according to the actual situation. result oriented.
