Embodiment 1

[0025] Example 1, see figure 1 , an embodiment of the ultra-fine LED display mask in the embodiment of the present invention includes a mask main body 1, and the mask main body 1 is provided with a plurality of through holes 11, and the through holes 11 are facing the positions of the lamp beads in the LED display screen. The mask main body 1 The length and width are both 50.12mm. The wall thickness of the light hole frame 12 of each through hole 1 is 0.1mm, while the overall thickness of the mask main body 1 is 0.45mm, the through holes 11 are arranged in a matrix, and the size of each light hole frame 12 is 1.14×1.14mm. Therefore, the LED display screen mask forms an ultra-fine grid, which can largely avoid black spots and mosaic phenomena, making the display screen more beautiful and clear.

Embodiment 2

[0026] Embodiment 2, in order to achieve the LED display screen mask of the specification in Embodiment 1, this embodiment designs a special molding mold, and the flow channel of the mold is designed as an H-shaped multi-point glue feeding method, and the mask is integrally formed into a grid structure . Such as figure 2 , image 3 and Figure 4 As shown, the mold includes a sprue 2 and a runner 3 connected to each other. The sprue 2 is H-shaped, and there are several runners 3 arranged in parallel with each other, and each runner 3 is distributed with several gates. 4.

[0027] There are preferably 10 runners 3 in this embodiment, and 10 gates are evenly distributed on each runner 3 . The number of runners 3 and the number of gates 4 on each runner 3 in this embodiment are only used to explain the design of the runners of the mold, and are not limited thereto. In order to meet the requirements of masks of different specifications, the number of runners and the gates dis...

Embodiment 3

[0030] Embodiment 3, based on the mold in above-mentioned embodiment 2, this embodiment provides a kind of molding method of LED display screen mask, such as Figure 5 shown, including steps:

[0031] S1. Filling glue into the prefabricated mold; wherein, the prefabricated mold includes an H-shaped main channel and a plurality of parallel runners, and each runner is evenly distributed with several gates;

[0032] S2. Controlling the mold to pour glue from multiple gates of each runner;

[0033] S3. Curing to form an LED display mask with an integrated grid structure.

[0034] In this embodiment, the molding method of multi-point injection of ultra-fine flow channels not only ensures the uniformity of filling, but also produces less nozzle material, shortens the molding cycle, reduces production costs, and provides guarantee for mass production.

Abstract

The embodiment of the invention discloses an ultrafine LED (Light Emitting Diode) display screen mask and a molding method thereof. The ultrafine LED display screen mask comprises a mask main body, wherein the mask main body is integrally molded into a grid structure by adopting a multi-point glue feeding manner of an H-type runner mold; the mask main body is provided with a plurality of through holes; the through holes are aligned to positions of lamp beads in an LED display screen; the thickness of a lamp hole framework wall of each through hole is 0.1mm; the size of each lamp hole frameworkis 1.14*1.14mm and the whole thickness of the mask main body is 0.45mm. Compared with the prior art, the ultrafine LED display screen mask has the advantages that an ultrafine grid of the LED mask isrealized and the width of the lamp hole framework wall is only 0.1mm, so that black spot and mosaic phenomena are avoided to a great extent and a picture of the display screen is more beautiful and clear. An ultrafine runner multi-point glue feeding technology ensures the uniformity of filling, a few of drainage opening materials are produced, the molding period is shortened and the production cost is reduced; and guarantees are provided for large-batch production.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an ultra-fine LED display screen mask and a forming method thereof. Background technique [0002] With the rapid development of LED technology, LED display screens are increasingly favored by people due to their advantages of thinness, energy saving, and environmental protection. LED masks play a role in protecting LEDs and have a great impact on display effects. important components. Most of the LED display screen masks have a grid structure, and the frame width of the existing masks is mainly between 0.2-0.4mm. At present, the LED pixel pitch has been designed to P1.2, and the corresponding requirements for the mask are more refined, so as to meet the requirements of more beautiful and colorful images. Since the width of the lamp hole of the LED mask and the overall thickness of the mask are extremely small, injection molding problems such as unsaturated glue, def...
