Description

A kind of two-color keycap production mold, method and two-color keycap produced therewith

technical field

The invention relates to the production field of a two-color keycap, in particular to a production mold and method for a two-color keycap and the two-color keycap produced therein.

Background technique

At present, the general two-color keycap is first injected into a transparent keycap, then sprayed with a layer of silver oil, and then sprayed with black oil as the background color, and then laser engraved characters on it through laser engraving, because each character is different, in laser engraving Generally, it is a single operation. After the laser engraving is completed, the individual keycaps are installed on the keyboard cover one by one. This method of laser engraving characters mainly has the following disadvantages: both the characters and the background color are easy to fade after long-term use; when the keycap is installed into the keyboard cover, the process is complicated and error-prone.

Step 2, use the first injection nozzle set in the first color mold cavity to extrude the injection material of the first color from the first color storage device into the first injection cavity to form the first color with raised characters full-page keycaps;

Step 3: After the first color full-page keycap is formed and stabilized, separate the lower mold and the first upper mold and remove the first upper mold, keeping the first-color full-page keycap on the lower mold;

Step 4, press the lower mold and the second upper mold with each other by moving the mold clamping device, the upper raised characters of the full-page keycap of the first color and the top below the mold cavity of the second color;

Step 5, use the second injection nozzle set in the second color mold cavity to extrude the injection material of the second color from the second color storage device into the second injection cavity to form a second color package that wraps the raised characters. The top of the raised character on the full-page keycap of the first color is flush with the top of the full-page keycap of the second color.

The product produced according to the above-mentioned mold is a two-color keycap, and the two-color keycap includes a first-color keycap and a second-color keycap, and the first-color keycap is installed under the second-color keycap; The top of the one-color keycap is integrally formed with raised characters, and the top of the second-color keycap is provided with a character hole adapted to the raised characters, and the raised characters pass through the character hole and the second-color key The top of the cap is flush.

Further, the keycaps of the first color are transparent keycaps, and LED light-emitting lamps are arranged under the keycaps of the first color.

Compared with the prior art, the beneficial effect of the present invention is that the mold can carry out full-page injection molding of the two-color keycap, the injection plastic used can be any color, and even transparent injection plastic is used to make the characters transparent and convenient for characters to emit light , without laser engraving or printing, the two-color keycaps produced have the advantages of never fading and colorful, and will not pollute the environment; because it is full-page injection molding and full-page installation on the keyboard, there is no need for keycaps one by one Single installation greatly saves a lot of manpower, and there is almost zero error rate and no mistakes.
