How to design internal thread injection molding products to be good?

Injection molding is a common production process, and internal thread injection molding products are one of the common products. However, the demoulding problem is always a difficult problem in the production process of internal thread injection molding products. Poor demoulding will not only affect product quality, but also may cause security risks. Therefore, this article will introduce the principle of internal thread injection molding product release and design optimization methods to help readers better understand and cope with this problem.

Let's take a look at the principle of internal thread injection molding product release. During the molding process of the internal thread injection product, the plastic melt is injected into the mold under high pressure, and the internal thread is formed after cooling. However, due to the influence of factors such as elastic deformation and friction of the plastic, the product may encounter difficulties when demoulding. Therefore, in order to improve the demoulding performance of internal thread injection products, some design optimization measures need to be taken.

Let's introduce some suggestions for design optimization of internal thread injection molding products. First of all, it is very important to choose suitable materials. Materials with a lower coefficient of friction are usually chosen, such as modified materials with added lubricants. Secondly, optimizing mold design is also the key. The mandrel diameter can be increased and the thread groove deepened, so that the product is easier to fall off. In addition, adjusting the processing technology is also an important means to improve the stripping performance. Through reasonable control of processing temperature, strengthen cooling and other measures to reduce the difficulty of product demoulding.

In practice, some auxiliary measures can also be taken to improve the demoulding performance of internal thread injection products. For example, the release slope can be set on the surface of the thread groove to reduce friction and improve the efficiency of the release. Or set an ejector device on the mandrel to help the product fall off smoothly.

The demoulding problem of internal thread injection molding products is a problem that needs to be paid attention to. By understanding its causes and taking corresponding design optimization measures and auxiliary measures, we can help manufacturers and consumers to better cope with this challenge and improve product quality and production efficiency. In the future, with the development of new materials and the improvement of processing technology, it is believed that the demoulding problem of internal thread injection products will be greatly improved.
