Injection mold with quick forming function for refrigerator plastic pieces

Abstract

The invention provides an injection mold with a quick forming function for refrigerator plastic pieces. The injection mold comprises a mounting frame, a fixed mold part, a movable mold part, a mounting shaft, a first driving mechanism and a film cutting assembly; the fixed mold part comprises a fixing plate and two fixed mold plates; the two sides of each fixed mold core are provided with a film unwinding roller and a film winding roller correspondingly; the movable mold part comprises a moving plate, a second driving mechanism and two movable mold plates, and the second driving mechanism is connected with the moving plate; the two movable mold plates are mounted at the bottom end of the moving plate and correspond to the two fixed mold plates; the movable mold plates are provided with mold cavities matched with the fixed mold cores; the film cutting assembly comprises a first connecting plate, a third driving mechanism and a film cutting frame capable of corresponding to the fixed mold cores; and the third driving mechanism is mounted on the first connecting plate, the film cutting frame is matched with the fixed mold cores, and the bottom of the film cutting frame is provided with retractable annular cutting knives. According to the injection mold, by arranging the film cutting assembly and a paint spraying assembly, before injection molding, thin films are attached to the fixed mold cores, and patterns or words are formed by spraying paint on the thin films through the paint spraying assembly.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a rapid-molding injection mold for refrigerator plastic parts. Background technique [0002] At present, there are several traditional processing methods for surface decoration of refrigerator injection-molded plastic components to form patterns or characters: 1. Printing directly on the surface of plastic components, including silk screen printing, pad printing or hot stamping; 2. Film panel sticking method, The film panel (decorative panel) that is to be printed with decorative graphic patterns in advance is directly pasted on the outer surface of the plastic component with pressure-sensitive adhesive (ie sticker); 3. Paint spraying to make the decorative surface; 4. Use laser Carving to form a decorative surface; 5. Make a decorative surface by electroplating; 6. Use water transfer printing and batch coating to make a decorative surface. The above-mentioned methods al...

AI Technical Summary

Problems solved by technology

The above-mentioned methods all carry out surface decoration after the injection molding of the plastic parts is completed. The decorative patterns and characters produced are all on the surface of the plastic parts, which makes the product easy to be scratched or worn during use, and has a long-term impact on the life of the product. Convenience and normal use produce a certain degree of adverse effects
