Problems solved by technology

[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 the frame is attached to the leather, 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 high.

Embodiment Construction

[0019] A skinning method for an injection molding frame, comprising an injection mold with an upper mold and a lower mold, a cavity for injection molding a frame is formed between the upper mold and the lower mold, and a hole leading to the bottom of the cavity is opened on the lower mold Air extraction holes, the upper mold is provided with a material injection hole leading to the top of the cavity; and the following steps are carried out: (1) Open the upper mold, and lay a layer of leather on the lower mold; (2) Close the upper mold; ( 3) Use air extraction equipment to pump air out of the air hole to make the leather fit the inner side of the cavity on the lower mold; (4) Inject molten injection molding material into the cavity through the injection hole; (5) Open the upper mold mold, take out the formed frame, and trim the excess leather fringe along the edge of the frame.

[0020] In this embodiment, the injection molding material is rubber or plastic, and the air extract...

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.

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...
