Technical Field

[0001] The utility model relates to the technical field of presses, in particular to a mold fixing device for a press. Background Art

[0002] With the progress of the times, people's development speed is constantly improving, and the demand for the use of various steel plates is also increasing. The press drives the flywheel through an electric motor, and drives the crank-connecting rod mechanism through the clutch and transmission gear to move the slider up and down, driving the stretching die to form the steel plate. The fixing method of the die is particularly important for the forming of the steel plate, so a die fixing device for the press is required.

[0003] Existing press molds are mostly fixed by bolts and clamps in fixed positions. Due to the wide variety of molds, when fixing different molds, in order to achieve a better fixing effect, it is necessary to adjust the clamping points of the clamps on the molds. However, it is difficult for inexperienced workers to make precise adjustments to the clamping points of the clamps, which reduces practicality. Utility Model Content

[0005] Further preferably, the positioning assembly also includes a rotating crank, which is fixedly connected to one end of the double-threaded screw, and the side surface of the rotating crank is sleeved with an anti-slip sleeve. By installing the positioning assembly, the rotating crank can be used to allow the double-threaded screw to rotate in the movable groove, thereby driving the two movable bottom blocks on the side surface to move in opposite or reverse directions in the movable groove, so that the indicator arrow on one side can accurately indicate the distance on one side of the scale groove. When fixing different molds, less experienced workers can make corresponding adjustments to the movable bottom block according to the clamping point distance parameters recorded by the mold, thereby achieving effective clamping of different molds, thereby improving practicality.

The top of the locking screw is fixedly connected to a rotating disk, and the top of the rotating disk is clamped with a convenient rod. By installing the locking assembly, when the movable bottom block is adjusted according to the recorded parameters, the worker can support the fixing piece, and then use the convenient rod to drive the rotating disk and the locking screw, so that the front end of the fixing piece is pressed down to the mold to achieve fixation. At the same time, the non-slip rubber block increases the fixing effect, and the mortgage spring prevents the fixing piece from rotating and deviating, thereby improving the fixing effect.

[0007] Further preferably, the top of the stamping table is fixedly connected to a supporting plate, the two movable grooves are symmetrically opened on both sides of the supporting plate, and the two scale grooves are symmetrically distributed on both sides of the supporting plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] In the utility model, by installing the positioning component, the double-threaded screw can be rotated in the movable groove by turning the crank, thereby driving the two movable bottom blocks on the side surface to move in opposite or reverse directions in the movable groove, so that the indicator arrow on one side can accurately indicate the distance on one side of the scale groove. When fixing different molds, less experienced workers can make corresponding adjustments to the movable bottom block according to the clamping point distance parameters recorded by the mold, thereby achieving effective clamping of different molds, thereby improving practicality.
