Abstract

The invention discloses an injection mold structure for high-gloss traceless automotive plastic products, which includes a bottom plate, the upper end of the bottom plate is symmetrically fixedly connected with two vertically arranged brackets, and the top ends of the two brackets are fixedly connected with a box body , a cavity is opened in the box. The present invention adopts the linkage design of the opening and closing of the upper mold and the box body. When the upper mold moves downward, the supporting block fixedly connected with it is driven by the ejector rod to move. After the supporting block moves, the connecting rod is driven to move according to the lever, and the connecting rod According to the movement of the lever, the baffle connected with it is driven to move upwards. At this time, the bellows is separated from the baffle, and the inlet pipe is connected to the steam output end of the external boiler. At this time, the steam enters the cavity, bellows, upper mold and lower mold. Complete a cycle and discharge from the exhaust pipe. Due to the cooling and heating effect of high-temperature steam, it can eliminate the welding marks on the injection mold, so that the injection molded product has a high-gloss and trace-free effect.

Description

technical field [0001] The invention relates to the technical field of injection molds for auto parts, in particular to an injection mold structure for high-gloss non-marking automotive plastic parts. Background technique [0002] Black high-gloss injection molding technology is applied to the development of mid-to-high-end models. The characteristics of this injection molding technology mainly include the following contents, core technology: high-gloss raw materials and high-gloss molds; main functions: use high-gloss raw materials and high-gloss molds to directly injection mold high-gloss parts without adding high-gloss paint Spraying, restore the most original material characteristics, giving people a feeling close to nature. However, the technical difficulties solved in the traditional technology are: due to the direct use of raw materials for injection molding, the requirements on the surface state of the parts are quite strict, and the generation of flow marks makes th...
