Plastic parts containing metal inserts are increasingly used in the automotive, military, and aerospace industries. This type of part effectively combines the advantages of plastics and metals, which not only improves the strength, rigidity, and wear resistance of the parts, but also makes the parts partially insulated, while reducing the overall weight and meeting the requirements of lightweighting. Elimold has accumulated a variety of patents over the years of engaging in injection molding services. The following are the details of the patents we have obtained.
Patent for the design of a large injection mold for the front section frame of an automobile with an insert
CAE technology was used to analyze the injection molding of the front section frame of an automobile with metal inserts, and a 10-point pouring scheme for the hot runner was determined, and possible problems that may occur during the injection of plastic parts were predicted. Combining the simulation analysis results and the structural characteristics of the plastic parts, a large injection mold for a sequential valve hot runner with one mold and one cavity was designed. The “inclined guide column + slider + side core” mechanism and the hydraulic core pulling mechanism were used to solve the demoulding difficulty caused by the large number of undercuts inside and outside the plastic parts and the large core pulling area; the problem of plastic parts sticking to the large slider was solved by designing a mechanical mechanism of “H-shaped block + hook + floating block”; an anti-fall mechanism was designed in the side core pulling structure located at the top, which is safe and reliable; the “top roller + nitrogen spring” combination method was used to drive and reset the ejection mechanism, which is highly efficient; each mechanism has an independent cooling circuit, and the mold temperature is uniform; the inserts are fixed by molding parts, ejector rods and strong magnets, and the positioning is simple and reliable. After the mold was put into production, it ran smoothly and the quality of the plastic parts met the requirements.
