LCD segment screen as a commonly used display technology, has been widely used in various electronic devices. Mold opening is an important link in the production process of segmented screens. It involves the design, manufacturing and debugging of molds. This article will introduce in detail the process and precautions for segment screen mold opening.

1. Mold Design

Before opening the mold, mold design needs to be carried out. According to the specifications, size and design requirements of the segment code screen, the corresponding mold structure is designed. In the mold design, the following aspects need to be considered:

Mold material: Choose appropriate mold materials, such as steel, aluminum, etc., to meet the strength, durability and processing requirements of the mold.

Mold structure: Reasonably designed mold structure, including the number of mold cavities, layout, runner design, etc., to ensure that the mold can meet production requirements.

Mold accuracy: Ensure the manufacturing accuracy of the mold to obtain high-quality segment code screen products.

2. Mold Manufacturing

After completing the mold design, enter the manufacturing stage. 

The following points need to be noted at this stage:

Manufacturing process: According to the mold material and structure, select the appropriate manufacturing process, such as milling, EDM, etc.

Precision control: During the manufacturing process, the accuracy of the mold must be strictly controlled to ensure that the size and shape of each part conforms to the design.

Surface treatment: Polishing, coating and other treatments are performed on the surface of the mold to improve the wear resistance and corrosion resistance of the mold.

3. Mold Debugging

① After completing the mold manufacturing, debugging is required. The main purpose of this stage is to check whether the mold meets the design requirements and adjust relevant parameters to ensure the production of high-quality segment screens. During the debugging process, you need to pay attention to the following points:

② Check the mold accuracy: Conduct a detailed inspection of the mold to ensure that the size and shape of each part meet the design requirements

③ Mold trial: Verify whether the mold can produce qualified segment code screen products through mold trial. During this process, it is necessary to detect and evaluate the size, appearance, performance and other aspects of the segment code screen.

④ Parameter adjustment: According to the mold trial results, adjust the mold-related parameters to optimize the segmented screen products produced.

⑤ Recording and improvement: Record the data and problems in the debugging process in detail for subsequent analysis and improvement. At the same time, the mold design or manufacturing process is optimized and improved according to the actual situation to improve production efficiency and product quality.

4. Precautions

During the mold opening process, process parameters such as mold temperature, injection pressure, and injection speed must be strictly controlled to ensure that the segmented screen products produced meet the requirements.

During the debugging process, it is necessary to carefully observe the appearance and performance of the segment code screen product to discover and solve problems in a timely manner. At the same time, pay attention to safe operating procedures to avoid accidents.

During the production process, the mold must be inspected and maintained regularly to ensure that it is in good working condition. At the same time, attention should be paid to cleaning and maintaining the production environment to avoid impurities and pollutants from affecting the products.

To sum up, the mold opening process of segment code screen involves many links and factors. In order to obtain high-quality segment code screen products, it is necessary to strictly control the process parameters and quality requirements of each link. At the same time, attention should be paid to safe operating procedures and maintenance work to ensure the smooth progress of the production process.
