Problems solved by technology
[0003] The above-mentioned existing technical solutions have the following defects: in the process of processing the picture frame with the above-mentioned process, since the picture frame needs to be painted and colored after the initial molding, even if the paint on the surface of the picture frame is dry after drying, but due to the gold oil on the Due to the presence of color, there are still some oil stains on the surface of the frame. Although the frame is cleaned before the final packaging, in order to increase the production speed, the general frame manufacturer only cleans it once during the final cleaning process, resulting in the surface of the frame still remaining. There are more oil stains, and the cleanliness of the frame surface is poor, which in turn reduces the quality of the produced frame

Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0032] refer to figure 1 , is the production process of a kind of spectacle frame disclosed by the present invention, comprises the following steps:
[0033] Step S1, injection molding, select the corresponding plastic particles according to the material of the required frame and send the plastic particles to the extruder, melt them through the extruder and then transport them to the molding mold for preliminary molding.
[0034] Step S2, cooling, taking out the preliminarily formed mirror frame from the forming mold and putting it into cold water for 20-30 minutes, preferably 25 minutes in this embodiment.
[0035] Step S3, painting and coloring, spraying and coloring according to the color of the required picture frame; the spray paint used includes gold oil, isoamyl acetate, diaminodiphenylmethane, and according to the mass ratio, gold oil:isoamyl acetate...

The present invention relates to a production process of a picture frame, which comprises step S1, injection molding, step S2, cooling, step S3, spraying and coloring, step S4, drying, step S5, one-time cleaning, and the picture frame is immersed in a storage tank filled with cleaning liquid. In the pool, move the cleaning frame up and down to clean for 30-40 minutes. The cleaning liquid is phosphorus-free degreasing powder: water according to the mass ratio of 1:20-25. Step S6, the second rinse, the frame is immersed in water In the water storage tank, and move the cleaning frame up and down to rinse for 40-50min; Step S7, wash three times, the mirror frame is immersed in the storage tank containing the cleaning solution of phosphorus-free degreasing powder: water according to the mass ratio of 1:40-45, And move the cleaning frame up and down to clean for 15-20min; step S8, rinse for four times, immerse the frame into a water storage tank different from step S6, and move the cleaning frame up and down to rinse for 30-35min; step S9 ,drying. The invention can effectively remove the oil stain on the picture frame, ensure the cleanliness of the picture frame surface, and improve the production quality of the picture frame.
Description
technical field [0001] The invention relates to the technical field of glasses production, in particular to a production process of a picture frame. Background technique [0002] The existing spectacle frame production process generally consists of injection molding of raw materials, cutting nozzles, and grinding nozzles to form a preliminary shape, and then deploy primer, gold oil and other paints to spray paint and color the preliminarily formed frame, and then dry it to increase the brightness of the surface of the frame. After that, drilling and milling grooves are used to facilitate the installation of subsequent mirror feet, and finally cleaning, drying and packaging are carried out. [0003] The above-mentioned existing technical solutions have the following defects: in the process of processing the picture frame with the above-mentioned process, since the picture frame needs to be painted and colored after the initial molding, even if the paint on the surface of the ...
