[0024] like Figure 1-4 As shown, a technical solution provided by the utility model:

[0025] A demoulding device for a mold for precision parts processing, comprising a base 1, a top plate 2 is arranged at the upper end of the base 1, the four corners of the base 1 and the top plate 2 are fixedly connected by columns 3, a mounting seat 4 is arranged between the upper and lower ends of the four columns 3, a hydraulic cylinder 7 is further arranged at the middle of the top end of the top plate 2, and the output shaft of the hydraulic cylinder 7 is fixedly connected to the top mounting seat 4; an upper mold 5 and a lower mold 6 are respectively arranged on the same side of the two mounting seats 4, a mounting mechanism is arranged between the mounting seat 4 and the upper mold 5 and the lower mold 6, and the mounting mechanism includes a movable groove 8, and the movable groove 8 is provided with a plurality of movable grooves. At the four corners of the mounting seat 4, a hand wheel 9 is provided on one side of the middle of the mounting seat 4, and a bidirectional screw 10 is provided on one end of the hand wheel 9 located on the inner side of the mounting seat 4, and movable bars 11 are movably installed at both ends of the bidirectional screw 10, and plug rods 12 are provided at both ends of the same direction of the two movable bars 11, and positioning blocks 13 are provided at the four corners of the upper mold 5 and the lower mold 6 near the mounting seat 4, and a slot 14 is provided in the middle of the positioning block 13, and baffles 15 are provided on both sides of the middle of the mounting seat 4, and a spring 20 is provided between the top plate 2 and the mounting seat 4 located outside the column 3;

[0026] In this embodiment, when the upper mold 5 is pressed down, the workpiece presses the ejector block 17, and the ejector block 17 drives the ejector rod 19 to compress the spring 2 18. When the upper mold 5 is lifted, the compressed spring 2 18 lifts the ejector rod 19 and controls the ejector block 17 to demold the workpiece from the lower mold 6, thereby achieving the purpose of facilitating demolding.

[0027] like Figure 3 and Figure 4As shown, both sides of the upper mold 5 and the lower mold 6 are provided with demoulding mechanisms, and the demoulding mechanisms include side grooves 16. The upper mold 5 and the lower mold 6 are provided with side grooves 16 at both ends of the same side, and a top block 17 is movably installed inside the side grooves 16. A plurality of springs 18 are provided inside the lower part of the upper mold 5 and the lower mold 6 near the side grooves 16, and a top rod 19 is provided at the top of each of the plurality of springs 18, and the top of the top rod 19 is fixedly connected to the top block 17;

[0028] In this embodiment, when removing the lower mold 6, turn the handwheel 9 on one side of the bottom mounting seat 4, the handwheel 9 controls the rotation of the bidirectional screw 10, and after the bidirectional screw 10 rotates, it controls the two movable bars 11 to move toward each other. When the two movable bars 11 move toward each other, they drive the insertion rod 12 to withdraw from the slot 14 in the middle of the positioning block 13, and then lift the positioning blocks 13 at the four corners below the lower mold 6 from the four movable grooves 8, thereby achieving the purpose of facilitating quick replacement.

[0029] Working principle: During processing, the workpiece is placed on the upper end of the lower mold 6 and is lifted by the two top blocks 17, and then the hydraulic cylinder 7 is started. The hydraulic cylinder 7 controls the upper mounting seat 4 to press down, and the mounting seat 4 controls the upper mold 5 to press down, so that the workpiece is stamped and formed. When the upper mold 5 is pressed down, the workpiece presses the top block 17, and the top block 17 drives the top rod 19 to compress the spring 2 18. When the upper mold 5 is raised, the compressed spring 2 18 lifts the top rod 19 and controls the top block 17 to demold the workpiece from the lower mold 6; if it is necessary to replace the upper mold 5 or the lower mold 6, just turn the handwheel 9 at the corresponding position. For example, when disassembling the lower mold 6, turn the handwheel 9 on one side of the bottom mounting seat 4, and the handwheel 9 controls the bidirectional screw 10 to rotate. After the bidirectional screw 10 rotates, it controls the two movable bars 11 to move toward each other. When the two movable bars 11 move toward each other, they drive the insertion rod 12 to withdraw from the slot 14 in the middle of the positioning block 13, and then lift the positioning blocks 13 at the four corners below the lower mold 6 from the four movable grooves 8.
