Abstract

The invention belongs to the technical field of dies, and particularly relates to a test method for an injection molding process of a newly developed die. According to the method, under the conditionthat a material physical property table and product information provided by a material supplier, production process requirements and die information are known, the injection molding process is pre-designed; continuous injection molding unsaturated die products are sampled and weighed on the premise that the products are not incompletely filled; when injection molding is the stablest, parameters such as a material temperature, a screw rotation speed, back pressure and suck back decompression are found; the freezing time of a pouring gate is found and determined through a weighing method, and the pressure maintaining time is selected; the optimum packing pressure is determined through the combination of weighing and size measurement; the shortest cooling time and die clamping force are determined by observing a plastic part. According to the method, the parameters are determined according to the requirements of the products and the production process, and the method strives for parameterstabilization. The die is adjusted to meet the requirements of the production process. The stablest injection molding parameters are found by the scientific method, so that the stability of later-stage production is ensured, and after the parameters are fixed, the injection molding production is very stable.

Description

technical field [0001] The technical field of molds of the present invention specifically relates to a newly developed mold injection molding process testing method. Background technique [0002] The existing method is: the tuner determines a range according to the material property table given by the material supplier. Debugging on the injection molding machine against the mold, and constantly adjusting the injection molding process based on experience to observe the product, so as to obtain a product that meets the requirements in appearance and size. At the same time record the molding process. [0003] Problems with existing methods: [0004] A. Determine the parameters according to the mold, let the parameters adapt to the mold, and the injection molding parameters cannot reach the most stable state. [0005] B. It is determined by the experience of technicians, and there are too many uncertainties. [0006] The production stability of injection molding parameters f...
