The lower die assembly is mounted on the machine base 1 via a fixed base plate 3. The lower die assembly includes a lower die 14, which is connected to two sets of guide rails and guide sleeves 11 via a lower die base 13. The two sets of guide rails and guide sleeves 11 ensure that the lower die direction is uniform. When the pressing force is applied, the guide rails and guide sleeves 11 are pressed against the fixed base plate 3, reducing the force on the linear slide rail slider 7, making the linear slide rail slider 7 more durable, and the accuracy is not affected. A spring 12 is provided on the guide rail and guide sleeve 11, and the die entry slide plate 1... When the machine is in operation, the spring 12 is in the open state, the guide rail sleeve 11 does not contact the fixed base plate 3, and no friction is generated; the mold entry slide 10 is fixed below the guide rail sleeve 11, the mold entry slide 10 is placed on two sets of linear slider slide rails 7, and the rear of the mold entry slide 10 is connected to the feeding cylinder 8. The two sets of linear slider slide rails 7 are installed on the fixed base plate 3. There are two start buttons 5 and one emergency stop button 6 in front of the fixed base plate 3. The equipment will only operate when both start buttons 5 are pressed at the same time to avoid accidental hand entry into the equipment; the fixed base plate 3 is located on the table panel 2 above the machine base 1.

[0020] In this embodiment, an adjustable limiting member 4 is provided on each of the left and right sides of the feeding cylinder 8. The two adjustable limiting members 4 are respectively installed at the ends of the two sets of linear slider rails 7. The adjustable limiting members 4 can adjust the front and rear positions of the lower mold 14. By using two adjustable limiting members 4, it is ensured that the position of the mold entry slide 10 is consistent and the accuracy is high each time it moves.

[0021] In this embodiment of the high-precision semi-automatic pneumatic press, when the workpiece is placed on the lower mold 14, the start button 5 is pressed simultaneously with both hands, the feeding cylinder 8 is activated, which drives the mold entry slide 10 to enter the corresponding position inside the equipment along with the workpiece. The pressing cylinder 21 is activated, which drives the pressing mold slide 19 (driving the upper pressing mold 15) to complete the pressing action. The pressure is maintained for the set holding time. After completion, the pressing cylinder 21 returns to its position, the feeding cylinder 8 returns to its position, and the mold entry slide 10 (including the workpiece) is pulled out together, and the pressed workpiece is removed.
