Description

Technical Field

[0001] The utility model relates to the technical field of lamp board processing, in particular to an injection mold used for lamp board processing. Background Art

[0002] The light board is the core component of the flat panel light, which is composed of LED lamp beads, circuit boards, power supplies and heat sinks. When the power is turned on, the LED lamp beads will emit light, which will pass through the light guide strips or reflective materials of the light board to evenly distribute the light to the entire lamp surface, thereby achieving lighting. The light board is usually fixed together with the flat panel light housing to ensure the stability and safety of the light board; injection molds generally refer to injection molding, which is also called injection molding, which is a molding method of injection and molding.

[0003] However, when the existing injection mold for lamp board processing is used, mold A and mold B must be closed together first. However, when mold A and mold B are closed together, mold B will generate impact force on mold A. Mold A is affected by the impact force for a long time, and a gap will be generated between mold A and mold B, which has a certain impact on the service life of mold A and mold B. At the same time, after the lamp board is formed in mold A and mold B, mold A and mold B need to be separated first, and then the staff needs to manually take out the formed lamp board. The operation steps are cumbersome, which has a certain impact on the efficiency of taking out the formed lamp board. Therefore, an injection mold for lamp board processing is provided.
