Injection molding frame veneer gluing method and device

Abstract

The invention relates to an injection molding frame veneer gluing method. An air exhaust device is utilized for carrying out outward exhausting on air exhaust holes, so that leather is attached to the inner side faces of cavities in lower moulds; molten injection molding materials are injected into the cavities through material injection holes; upper moulds are opened, and a formed frame is taken out; and meanwhile, the invention further relates to an injection molding frame veneer gluing device. The device comprises a machine table, and an intermittent-rotating annular rotating disc is arranged on the machine table; a plurality of injection moulds are arranged on the annular rotating disc at intervals, and an injection molding machine is arranged at the position, arranged on the center of the annular rotating disc, of the machine table; a material injecting station and an opening and closing mould station are arranged on the machine table, and the injection moulds comprise the upper moulds and the lower moulds; and the air exhaust holes leading to the bottoms of the cavities are formed in the lower moulds, and the material injection holes leading to the tops of the cavities are formed in the upper moulds. Frame injection molding and veneer gluing are carried out at the same time, the manufacturing technology is simplified, the use amount of glue is saved, the manufacturing cost is saved, and the method and device are suitable for frames with figures, and modeling is attractive.

Description

technical field [0001] The invention relates to a skinning method and device for an injection molding frame. Background technique [0002] At present, the method of pasting leather on the injection molding frame (such as injection molding photo frame, injection molding picture frame, etc.) is to directly glue the leather to the surface frame through glue. This method only uses the frame with a relatively simple structure. If there is a pattern When attaching the leather to the frame, the corresponding pattern cannot be formed on the leather. At the same time, this method of pasting the skin causes the manufacturing process of the frame to be complicated and the manufacturing cost is relatively high. Contents of the invention [0003] In view of this, the object of the present invention is to provide an injection molding frame skinning method which has a simple manufacturing process and effectively reduces manufacturing costs; meanwhile, the invention also provides an injec...
