Description

technical field [0001] The present application relates to the field of molds, in particular to a three-plate mold drawing mechanism. Background technique [0002] With the popularization and development of automobiles, people's enjoyment of automobiles has also increased, that is, people are paying more and more attention to whether automobiles can meet more needs. Automobiles are not only a means of transportation, but also a means of providing people with Tools for a comfortable life. In addition to the increasing demand for vehicle performance, vehicle interiors have also become a major concern. [0003] There are many types of existing automotive interior parts, most of which are cast and formed by injection moulds, while some more complex interior parts need to be cast and formed by using a three-plate mold. The three-plate mold generally includes a lower mold, an upper mold, a nozzle plate and a face plate. The injection molded product is located between the lower mo...
