Embodiment Construction

[0016] ①Cleaning treatment: Clean the surface of the mold with conventional detergents such as water, soap liquid or washing powder, and then degrease at a high temperature of 300-500°C (eg 300°C, 380°C, 420°C, 500°C) for 40 ~120 minutes (eg 40 minutes, 80 minutes, 120 minutes);

[0017] ②Sand blasting: Cool the mold treated in step ① to 80°C~100°C (for example, 80°C, 90°C, 100°C), perform surface sandblasting treatment, and use gas to remove dust from the mold surface;

[0018] ③Painting: Spray polytetrafluoroethylene paint evenly on the surface of the mold, and spray the paint in three times. After the first uniform spraying, dry it at 160°C-200°C, cool it to 30°C-50°C, and use air to spray the mold surface. Dust off, then spray a second coat evenly, followed by a third coat. The PTFE paint sprayed in the first pass is EK-1909BNK, the PTFE paint sprayed in the second pass is EK-3809M3, and the PTFE paint sprayed in the third pass is EK-3800C3. After spraying, heat and dry,...

Description

Technical field: [0001] The invention relates to a mold and a production method, in particular to a hot-press forming mold and a production method. Background technique: [0002] Existing hot press molding molds such as car roofs require the use of a release agent in the production process, and the surface is adhesive, the stability of the product size tolerance is poor, and the accuracy is difficult to guarantee. Invention content: [0003] The purpose of the present invention is to provide a reasonable structure, no adhesion on the mold surface, good stability of product size tolerance, high precision auto interior parts "Teflon" coating hot pressing molding mold and production method. [0004] Technical solution of the present invention is: [0005] A "Teflon" coating thermoforming mold for automotive interior parts, including a mold body, is characterized in that a polytetrafluoroethylene paint layer is coated on the surface of the mold body. [0006] A method for pr...
