Multicoloured label sheet forming method

Abstract

The invention discloses a forming method for multi-color mark, it produces at least a pattern plate with at least one set of mold, and the pattern plate has a lining board and pattern unit with the different color to the lining and fixed on the lining board. Then a forming mold is produced, the mold has a bottom mold and a top mold which can cover the bottom one. When the pattern plate is embedded in the bottom mold, and the top mold is filled with back glue board billet, the forming mold can be carried on with hot pressing; the multi-color mark can be acquired after the mold is opened, and the multi-color mark plate has a back glue board, at least one pattern plate on the board with different color.

Description

technical field [0001] The invention relates to a label sheet made of a thermosetting plastic material, in particular to a molding method of a multi-color label sheet. Background technique [0002] Such as figure 1 As shown, the steps of generally making label sheets by needle injection include: (1) preparing a forming mold 1 and a plurality of syringes 2, the forming mold 1 has at least one cavity group 101, and the previously prepared The slurry is loaded in syringe 2. (2) Manually operate the injector 2 to inject the slurry into specific cavity groups 101 . (3) Cleaning up the slurry overflowing in the cavity group 101 in the unspecified position. (4) Carry out a curing operation, and solidify the slurry injected into the cavity group 101 . (5) Cooling. (6) Take out the semi-finished product. (7) Trimming the rough edges. (8) Finished products. [0003] When it is desired to make a label sheet of multi-color combination, the operation steps (2) to (4) can be repea...

AI Technical Summary

Problems solved by technology

[0005] 1. Labor consumption: filling the slurry is completely manual operation, and it must be a technical manual operation

[0006] 2. For the dimple group 101 with extremely small operation surface, it is necessary to use a needle body with a very small aperture, and even observe it with a magnifying glass, and when injecting, the needle body and the forming mold will cause mutual damage

[0007] 3. For the small cavity group 101 on the operation surface, the operator can only fill the slurry at a rough position, and the amount and force of the squeezed slurry are completely determined by the operator's experience. For non-specific cavity groups 101, it is still necessary to use rags, brushes, foam, needles, etc. to clean up the spilled parts, which is quite troublesome to operate and the production capacity is low

[0008] 4. The eye fatigue intensity of operators is high, and young people with good eyesight are generally hired, and because it is easy to cause lifelong damage to eyesight, the turnover rate of operators is high
