Description

Technical Field

[0001] The utility model relates to the technical field of display screen processing, in particular to a display screen pressing mould. Background Art

[0002] When processing and assembling electronic devices with screens, the screen needs to be pressed to ensure that the circuits on the back of the screen are completely fitted.

[0003] Currently, commonly used screen pressing technologies mainly include manual pressing and pneumatic pressing. However, no matter manual pressing or pneumatic pressing, most of the time, the screen is in single-point contact during pressing, that is, pressure is applied at a single point on the screen. Therefore, the pressure on the screen is concentrated on the connection between the hand or the cylinder and the screen, resulting in uneven force at various locations during screen pressing. The position of the screen close to the hand or the cylinder is subjected to greater pressure and is easily damaged, while the position of the screen far away from the hand or the cylinder is subjected to less pressure, resulting in insufficient screen fit after pressing. At the same time, when the existing display screen pressing mold is used, when the display screen is placed in the pressing chamber for pressing, there is no buffering force between the molds during the pressing process, which can easily lead to damage to the pressing.

[0004] Therefore, the utility model provides a display screen pressing mold. Utility Model Content

[0005] In view of the defects in the prior art, the display screen pressing mold provided by the utility model can solve:

[0006] When the existing display screen pressing mold is used, the force on different parts of the screen is uneven during pressing. The screen near the hand or the cylinder is subjected to greater pressure and is easily damaged, while the screen away from the hand or the cylinder is subjected to less pressure, resulting in the problem of insufficient fit of the screen after pressing.

[0010] Furthermore, the upper mold structure includes an upper mold body and an inner pressure plate at its inner side, a spring rod is fixedly connected between the inner pressure plate and the upper mold body, a pressure plate opening is opened on the surface of the upper mold body, a pressing rubber pad is fixedly connected to the bottom end of the inner pressure plate, and a positioning seat is fixedly arranged on the top surface of the inner pressure plate.

[0011] Furthermore, the pressing cavity is rectangularly opened in the center of the surface of the bottom mold, and the outer positioning cavity is opened in a "loop" shape along the outer side of the pressing cavity, and the pressure plate opening is trapezoidally opened.

[0012] Furthermore, the upper mold body is arranged in an "M" shape as a whole, with its two ends of the bottom protruding vertically downward, and the middle section of the bottom is arranged horizontally, and the two ends of the bottom of the upper mold body are embedded in the external positioning cavity at the same time, and the inner pressure plate is arranged in a rectangular pressure plate and embedded in the pressing cavity at the same time.

[0013] Furthermore, multiple groups of spring rods are arranged, which are located at the bottom corners of the inner pressure plate and the upper mold body, and the pressed rubber pads are arranged in the shape of rectangular rubber plates along the surface of the inner pressure plate.

[0014] Furthermore, the positioning seat is arranged along the top surface of the inner pressure plate in an "X"-shaped seat protrusion.

[0015] Furthermore, the auxiliary pressing plate is arranged in an "X" shape as a whole and is embedded with the positioning seat.

[0030] The upper mold body 9 is set in an "M" shape as a whole, with its two ends of the bottom protruding vertically downward, and the middle part of the bottom is set horizontally. The two ends of the bottom of the upper mold body 9 are embedded in the external positioning cavity 8 at the same time, and the inner pressure plate 11 is set in a rectangular pressure plate and embedded in the pressing cavity 7 at the same time. Multiple groups of spring rods 14 are arranged, located at the inner pressure plate 11 and the bottom end corners of the upper mold body 9. The pressing pad 12 is arranged in a rectangular rubber plate along the surface of the inner pressure plate 11. The upper mold body 9 is used to ensure the positioning and pressing of the bottom mold 6 and the entire upper mold structure 5. The inner pressure plate 11 cooperates with the pressing pad 12 on its surface to achieve the effect of preliminary positioning and pressing of the external display screen in the pressing cavity 7. The spring rod 14 is used to provide a buffer between the inner pressure plate 11 and the upper mold body 9.

[0031] During the pressing operation, the external display screen is placed in the pressing cavity 7, and then the first hydraulic rod 2 is started to drive the entire upper mold structure 5 to descend, so that the inner pressure plate 11 is embedded in the pressing cavity 7, so that the inner pressure plate 11 preliminarily positions and presses the external display screen.
