[0020] like Figure 1-Figure 4 As shown, the earphone die-casting mold proposed by the utility model comprises a lower mold 1, an upper mold 2 and an upper mold structure;
[0021] The upper mold 2 is arranged on the lower mold 1 and is detachably connected; the lower mold 1 is provided with a first cavity 6 and a second cavity 7; the upper mold 2 is provided with a feed port 5; there are two feed ports 5, one is located above the first cavity 6, and the other is located above the second cavity 7; the upper mold structure includes a semi-cylinder 12 and an upper module 13; the semi-cylinder 12 and the upper module 13 are both provided with multiple; the semi-cylinder 12 and the upper module 13 are both arranged on the upper mold 2; the semi-cylinder 12 and the upper module 13 are both abutted against the lower mold 1; the upper module 13 is provided with a pressing groove 14; there are multiple pressing grooves 14.
[0022] The lower mold 1 is provided with a latch hole 4; the upper mold 2 is provided with a latch 3; a plurality of latches 3 and latch holes 4 are provided; the latch 3 is embedded in the latch hole 4, and the lower mold 1 is clamped with the upper mold 2.
[0023] An ejection rack 8 is slidably disposed on the lower mold 1 ; two ejection racks 8 are provided, one ejection rack 8 is located below the first cavity 6 , and the other ejection rack 8 is located below the second cavity 7 .
[0024] An elastic member 9 is provided on the lower mold 1 ; two elastic members 9 are provided; two ends of the elastic member 9 are connected to the lower mold 1 and the ejection frame 8 respectively.
[0025] A second mounting block 11 is disposed on the lower mold 1 .
[0026] A first mounting block 10 is disposed on the upper mold 2 .
[0027] In this embodiment, the lower mold 1 and the upper mold 2 are first installed on the die-casting equipment. First, the upper mold 2 is installed on the fixed and immovable component by means of the first installation block 10, and the two feed ports 5 are connected to the pressure component. Then, the lower mold 1 is installed by means of the second installation block 11, and the lower mold 1 is installed on the movable component, so that the upper mold 2 and the lower mold 1 can be connected and separated, and a pushing component is installed at the ejection frame 8 to push the ejection frame 8 to move. After the installation is completed, the lower mold 1 and the upper mold 2 are overlapped, and then the pressure component is used to push the two molds respectively. The material is pressed into the feed port 5 so that the material quickly fills the first cavity 6 and the second cavity 7. After the material in the first cavity 6 and the second cavity 7 is cooled and formed, the lower mold 1 is moved to release the clamping connection between the lower mold 1 and the upper mold 2, so that the lower mold 1 and the die-casting are away from the upper mold 2, and then the two ejection racks 8 are pushed. The ejection racks 8 eject the die-castings in the first cavity 6 and the second cavity 7 from the lower mold 1. The ejection racks 8 return to their original positions under the action of the elastic member 9, and the two die-castings fall into the blanking box prepared in advance. The two die-castings are aligned and placed as shown in the figure. Figure 5 The die-casting part shown in the figure, then the lower mold 1 is moved to its original position, so that the lower mold 1 and the upper mold 2 are aligned and engaged again, and then the die-casting can be continued, which is simple, fast and efficient; wherein, the latch 3 and the latch hole 4 have a guiding function, and whether the latch 3 can be embedded in the latch hole 4 can determine whether the lower mold 1 and the upper mold 2 are aligned and engaged, thereby also knowing whether the die-casting can be normal.
