一、模具设计的基本问题注射成形必须具有各种各样的相关条件,而最本质的是塑料、注射机、模具这三个因素及其使用技术,换句话说,有成形技术,才可能进行注射成形。设计制品时,首先选定塑料,根据用料、成品尺寸、重量、质量要求以及预想的模具结构选用注射成形机。以注射成形机将熔融的塑料注入由安装在成形机上的模腔型板和模芯型板所构成的空隙内,待其冷固后即制成注射成形品。
First, the basic problems of mold design Injection molding must have a variety of related conditions, and the most essential is the plastic, injection molding machines, mold these three factors and their use of technology, in other words, there is a forming technique, it is possible Injection molding. Design products, first select the plastic, according to the use of materials, product size, weight, quality requirements and the expected mold structure selection of injection molding machine. Molten plastic is injected by an injection molding machine into a cavity formed by a cavity plate and a core plate mounted on a forming machine, and the resulting product is cooled to form an injection-molded product.
