AUTOMOBILE, AUTOMOBILE PLATED PART, AUTOMOBILE PLATED PART MOLD AND MANUFACTURING METHOD THEREOF
The application belongs to the technical field of automobile plated part, and in particular relates to an automobile, an automobile plated part, an automobile plated part mold and a manufacturing method thereof. The method for manufacturing automobile plated part mold comprises the steps of: establishing a first simulation model of the automobile plated part mold based on a set shape of the substrate of the automobile plated part; using the first simulation model to simulate injection process of the substrate to obtain a first simulation substrate; performing at least one modification processing on the first simulation model, so that a second simulation model thus obtained satisfies the following requirements: using the second simulation model to simulate the injection process of the substrate to obtain a second simulation substrate conforming to the set shape; manufacturing the automobile plated mold according to the second simulation model.
Injection molding warp prediction
Methods, systems, and apparatus, including medium-encoded computer program products, for injection molding warp prediction include: obtaining a mold model and measured shrinkage data for at least one material, predicting an amount of warpage for a part manufactured using the mold by computational simulation of an injection molding process, where the computational simulation uses an internal residual stress model for the part that uses calibrated values for both a coefficient of thermal expansion and an elastic modulus and/or a Poisson's ratio of the at least one material, in at least one direction, for at least thermal stress due to cooling and pressure compensation during and/or after a packing phase of the injection molding process, in accordance with the measured shrinkage data for the at least one material, and providing the amount of warpage predicted for the part manufactured using the mold.
Injection molding part with “zero draft” design and manufacturing methodologies
A method may comprise generating a first electronic model of a workpiece to be manufactured using an injection-molding process. The first electronic model may then be analyzed and the workpiece in the first electronic model may then be selectively distorted according to the analysis. A second electronic model of the distorted workpiece may then be generated. The workpiece may then be injection-molded within a mold generated using the second electronic model. Thereafter, the workpiece may be cooled such that the injection-molded workpiece gradually assumes the shape or substantially the shape of the workpiece in the first electronic model.
