Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example (b): referring to fig. 1-4, a 5G mobile phone motherboard SMT press-fit carrier includes an upper die 11 and a lower die 12, a vertical column 21 is fixed on the lower die 12 along a position perpendicular to the upper surface of the lower die 12, a strip-shaped press block 23 is rotatably connected to the upper end of the vertical column 21, and a through hole 13 having a size equal to that of the press block 23 is formed in the upper die 11; after the pressing block 23 passes through the through hole 13, the pressing block 23 is rotated, and the pressing block 23 abuts against the upper surface of the upper die 11. Utilize the length and the width difference of briquetting 23 for briquetting 23 rotates certain angle after, briquetting 23 will contradict like this at the upper surface of last mould 11, go up mould 11 and lower mould 12 and can't throw off, only when briquetting 23 and through-hole 13 overlap completely, go up mould 11 and lower mould 12 and just can throw off, and whole in-process only needs to rotate 90 degrees with briquetting 23 and just can realize the dismouting of going up mould 11 and lower mould 12, makes the dismouting that goes up mould 11 and lower mould 12 can be quick.

Referring to fig. 1 to 4, four columns 21 and four compacts 23 are uniformly arranged on the lower mold 12. A T-shaped connecting rod 22 penetrates through the upright post 21 along the axial direction of the upright post 21, and a pressing block 23 is fixedly connected with the upper end of the connecting rod 22. A threaded sleeve 26 is embedded on the lower die 12 along the direction perpendicular to the upright post 21, a spring 25 and a steel ball 24 are arranged in the threaded sleeve 26, the steel ball 24 is abutted against the connecting rod 22, a limiting hole 27 matched with the steel ball 24 is formed in the connecting rod 22, and when the rotating pressing block 23 rotates to enable the limiting hole 27 to be abutted against the steel ball 24, the spring 25 pushes the steel ball 24 to be matched in the limiting hole 27.

Referring to fig. 2 to 5, since there are four pressing blocks 23, only when all the pressing blocks 23 coincide with the through holes 13, the pressing blocks 23 can pass through the respective through holes 13, the upper die 11 and the lower die 12 can be attached, and the pressing blocks 23 can rotate, it is difficult to ensure that all the pressing blocks 23 correspond to the respective through holes 13; the spring 25 pushes the steel ball 24 to enable the steel ball 24 to abut against the connecting rod 22, when the pressing block 23 is overlapped with the through hole 13, the steel ball 24 is abutted to the limiting hole 27, the connecting rod 22 rotates to overcome the elastic force of the spring 25, the pressing block 23 is prevented from rotating, and the pressing block 23 cannot shake in the assembling process of the upper die 11 and the lower die 12 and always keeps the overlapped state with the through hole 13. When the upper die 11 and the lower die 12 are assembled, the pressing block 23 is manually driven to rotate.

Referring to fig. 2-5, a wedge surface is formed on a surface of the pressing block 23 contacting the upper die 11, and a wedge 31 for guiding the pressing block 23 to rotate is fixed on an upper surface of the upper die 11. After the pressing block 23 rotates, the wedge surface contacts with the surface of the wedge 31, so that pre-tightening force can be applied to the upper die 11, and a gap between the upper die 11 and the lower die 12 is prevented.

Referring to fig. 2 to 5, a stopper 33 is fixed to the upper surface of the upper mold 11, when the pressing block 23 abuts against the stopper 33, the pressing block 23 stops rotating, and magnets 32 are embedded in the abutting surfaces of the stopper 33 and the pressing block 23. When the pressing block 23 rotates 90 degrees after passing through the through hole 13, the magnet 32 on the pressing block 23 is attached to the magnet 32 on the stopper 33, so that the pressing block 23 can rotate reversely by overcoming the attraction of the magnet 32, and the position of the pressing block 23 cannot be changed in the process of attaching the upper die 11 and the lower die 12.

The implementation principle of the above embodiment is as follows: firstly adjusting all the pressing blocks 23 to enable all the pressing blocks 23 to be overlapped with the through holes 13, rotating the pressing blocks 23 after the upper die 11 and the lower die 12 are attached, enabling the lower surfaces of the pressing blocks 23 to be abutted against the upper surface of the upper die 11, and fixing the upper die 11 and the lower die 12 together; when the upper die 11 and the lower die 12 need to be disassembled, the pressing block 23 is rotated reversely, so that the pressing block 23 and the through hole 13 are overlapped, and the upper die 11 and the lower die 12 can be separated.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
