[0002] A display is usually also called a monitor. A display belongs to the I / O device of a computer, that is, an input and output device. It is a display tool that displays certain electronic files onto a screen through a specific transmission device and then reflects them into the human eye. According to different manufacturing materials, it can be divided into: cathode ray tube displays, plasma displays, liquid crystal displays, etc. The back of the display is usually processed by stamping dies. A stamping die is a special process equipment that processes materials into parts in cold stamping processing, called a cold stamping die. Stamping is a pressure processing method that applies pressure to materials using a die installed on a press at room temperature to cause separation or plastic deformation, thereby obtaining the required parts.

[0003] In the prior art, there are still certain deficiencies in the demoulding mechanism used in the processing of display backplanes. Traditional demoulding mechanisms usually use the method of ejecting for demoulding. When the workpiece is not completely cooled and formed, the ejector rod is likely to leave marks on the surface of the processed workpiece, increasing the defective rate of defective products. Content of the Utility Model

[0004] The purpose of the utility model is to provide a demoulding mechanism for a display backplane to solve the problem that traditional demoulding mechanisms usually use the method of ejecting for demoulding.

Inflatable demoulding ports are arranged at both ends of the bottom surface inside the stamping die cavity. An upper movable frame is arranged on the bottom surface of the lower die base. The upper movable frame is connected to a lower fixed frame through a return spring. The lower fixed frame is arranged above a bottom plate. Sealing top plates are arranged at both ends inside the lower fixed frame. The demoulding mechanism is arranged at the middle position inside the lower fixed frame.

[0006] In a further embodiment, the positions of the four corners on the outer sides of the lower fixed frame and the upper movable frame are all slidably connected through limit sliders and limit chutes, and the limit sliders are fixedly connected to the upper movable frame through threads.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. The demolding mechanism in this utility model adopts an inflatable method. This demolding method can play two roles. First, through the high-pressure air flow, the workpiece can be flushed and separated from the mold cavity to achieve the demolding effect, which has the function of demolding. Second, through the high-pressure air flow rate, the surface of the workpiece and the bottom surface of the mold cavity can be quickly cooled, enabling the workpiece to be quickly cooled and formed, which has the function of cooling. The demolding principle is simple, avoiding damage to the surface of the workpiece, being easier to operate, and the cross-section of the high-pressure inflatable port is a V-shaped structure. This structure can divide the inflatable port into two discharge routes, expanding the area covered by the air flow, enabling the air flow to be quickly distributed into the inflatable demolding port and accelerating the demolding speed.
