Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0022] Specifically, the convenient ejection assembly 7 includes an ejection rod 71, a limit spring 72, a movable rod 73, a connecting rod 75, a lifting block 76, a guide rod 77, a positioning spring 78, a shift block 79 and a fixed rod 710, wherein a guide rod 77 is arranged in the middle of the lower mold 6, the upper end surface of the guide rod 77 is sleeved with the limit spring 72, the bottom end of the limit spring 72 is arranged with the movable rod 73, the bottom end of the movable rod 73 is arranged with a lifting block 76, connecting rods 75 are symmetrically arranged on both sides of the lifting block 76, the bottom end of the connecting rod 75 is arranged with a shift block 79, the interior of the shift block 79 is penetrated by a fixed rod 710, the surface of the fixed rod 710 is sleeved with the positioning spring 78, and the upper end surface of the movable rod 73 is arranged with an ejection rod 71.

[0023] When the molded frame needs to be taken out by adopting the above technical scheme, the two sets of shift blocks 79 are pressed at the same time to make them slide along the fixed rod 710. At the same time, the positioning spring 78 is compressed and the connecting rod 75 lifts the lifting block 76 and rises along the guide rod 77. The lifting block 76 moves to lift the movable rod 73 and compresses the limit spring 72. At this time, the ejector rod 71 passes through the through hole at the bottom end of the frame mold groove 5 to eject the molded frame from the interior of the lower mold 6, thereby improving the convenience of product retrieval. When the shift block 79 is released, the positioning spring 78 resets to drive the shift block 79 to reset and the lifting block 76 is forced to fall back. The limit spring 72 resets to make the movable rod 73 abut against the surface of the limit block 74, thereby ensuring that the reset ejector rod 71 can block the through hole, thereby ensuring the quality of equipment use, improving the convenience of material retrieval, and saving human resources.

[0024] Specifically, a limiting block 74 is provided inside the lower mold 6 corresponding to the movable rod 73 , and a through hole is provided at the bottom end of the frame mold groove 5 corresponding to the ejection rod 71 .

[0025] By adopting the above technical solution, it is ensured that the top end of the ejection rod 71 is flush with the through hole after the movable rod 73 is reset, thereby improving the blocking effect and ensuring the quality of the frame.

[0026] Specifically, the connecting rod 75 is connected to one side of the shifting block 79 and the lifting block 76 through a pin shaft, and the surface of the shifting block 79 is provided with anti-slip grooves.

[0027] By adopting the above technical solution, it is ensured that after the shifting block 79 moves, the lifting block 76 can be pushed by the connecting rod 75, thereby improving the use quality of the equipment.

[0028] When this embodiment is in use: when it is necessary to take out the formed frame, the two groups of shift blocks 79 are pressed at the same time to make them slide along the fixed rod 710, and at the same time the positioning spring 78 is compressed and the connecting rod 75 lifts the lifting block 76 and rises along the guide rod 77, the lifting block 76 moves to lift the movable rod 73 and makes the limit spring 72 compressed. At this time, the ejector rod 71 passes through the through hole at the bottom end of the frame mold groove 5 to eject the formed frame out of the lower mold 6, thereby improving the convenience of product retrieval. When the shift block 79 is released, the positioning spring 78 resets to drive the shift block 79 to reset and the lifting block 76 is forced to fall back, and the limit spring 72 resets to make the movable rod 73 abut against the surface of the limit block 74, ensuring that the reset ejector rod 71 can block the through hole, thereby ensuring the quality of equipment use, improving the convenience of material retrieval, and saving human resources.

[0035] The working principle and use process of the utility model: when the utility model is used, when producing the frame of electronic products, it is necessary to use a mold to form the frame. Before production, the upper mold 2 and the lower mold 6 can be installed inside the splicing frame 16 for use, and the pull rod is pulled to make the clamping plate 12 rotate along the torsion spring 11, and then the clamping grooves in the upper mold 2 and the lower mold 6 correspond to the clamping plate 12 and the clamping plate 12 is loosened, and the torsion spring 11 is reset at this time so that the clamping plate 12 is inserted into the upper mold 2 and the lower mold 6, and then after the injection molding is completed, the two-way screw 13 is rotated to make the upper mold 2 and the lower mold 6 close to each other along the guide column 15, ensuring that the upper mold 2 and the lower mold 6 can be completely fitted, and the positioning pin 3 can be inserted into the positioning seat 4, to ensure the accuracy and stability of the equipment positioning, and improve the frame molding quality;

[0036] When it is necessary to take out the formed frame, the two sets of shift blocks 79 are pressed at the same time to make them slide along the fixed rod 710. At the same time, the positioning spring 78 is compressed and the connecting rod 75 lifts the lifting block 76 and rises along the guide rod 77. The lifting block 76 moves to lift the movable rod 73 and compresses the limit spring 72. At this time, the ejector rod 71 passes through the through hole at the bottom of the frame mold groove 5 to eject the formed frame out of the lower mold 6, thereby improving the convenience of product removal. When the shift block 79 is released, the positioning spring 78 resets and drives the shift block 79 to reset and the lifting block 76 is forced to fall back. The limit spring 72 resets and makes the movable rod 73 abut against the surface of the limit block 74, ensuring that the reset ejector rod 71 can block the through hole, thereby ensuring the quality of equipment use, improving the convenience of material removal, and saving human resources.
