Description

A mold clamping structure for machining

Technical Field

The utility model belongs to the technical field of machining die fixing, and in particular relates to a machining die clamping structure.

Background Art

Machining dies refer to the processing of forming and blanking tools, and also include shearing dies and die-cutting dies. Usually, the die consists of two parts: the upper die and the lower die. The steel plate is placed between the upper and lower dies, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the die is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed with dies.

When making a mold, the mold is usually clamped by a mold clamping structure before making the mold. However, the existing mold clamping structure is usually bidirectional clamping or uses an electric cylinder to push a fixed ring to enclose and clamp, resulting in an inability to adjust the clamping shape and an inability to adapt to molds of different shapes.

The utility model discloses a mold clamping structure for machining. The mold is clamped and fixed at multiple angles by a clamping device to prevent the mold from slipping. The mold is fixed by rotating different screws to make extrusion rods in different directions drive the extrusion head to move toward the mold, thereby adapting to molds of different shapes.

DETAILED DESCRIPTION

As shown in Figures 1 and 2, the utility model is a clamping structure for a machining mold, comprising a base 1, a clamping device 2 is connected to the upper part of the base 1, and the clamping device 2 is used to fix the mold. There are multiple clamping devices 2 and they are evenly arranged around the upper part of the base 1, so that different molds can also be clamped and fixed. The clamping device 2 includes: a fixed block 21, a rotating block 22, a screw 23, an extrusion block 24, an extrusion rod 26, a spring 25 and a clamping block 27. The fixed block 21 is fixedly connected to the upper part of the base 1, and the screw 23 passes through the fixed block 21 and is threadedly connected to the fixed block 21. The screw 23 is controlled to move horizontally by rotating the screw 23. The rotating block 22 is fixedly connected to one end face of the screw 23, and the rotating block 22 is connected to a handle 5. The other end of the screw 23 is rotatably connected to the extrusion block 24, and a telescopic rod 7 is connected between the extrusion block 24 and the fixed block 21, and the extrusion block 24 can be prevented from rotating by the telescopic rod 7. The extrusion block 24 is hollow inside, and one end of the extrusion rod 26 passes through the extrusion block 24 and is slidably connected to the extrusion block 24, so that the extrusion rod 26 can be retracted into the extrusion block 24. The upper end of the extrusion rod 26 is connected to the extrusion head 3, and the extrusion head 3 is made of rubber to prevent scratching the mold. The spring 25 is located between the extrusion head 3 and the extrusion block 24. There are two springs 25 and they are respectively located on both sides of the extrusion rod 26. The spring 25 can achieve a force unloading effect. The extrusion block 24 is provided with a slot 6, and one end of the clamping block 27 extends into the slot 6 and is rotatably connected to the extrusion rod 26. The clamping block 27 is arranged in an arc shape, so that when the extrusion head 3 contacts the mold, the extrusion rod 26 is pressed down, and the clamping block 27 fixes the mold. The other end of the clamping block 27 extends out of the slot 6, and the slot 6 is rotatably connected to the rotating shaft 4. There are two rotating shafts 4 located on both sides of the slot 6, and the two rotating shafts 4 are connected to the clamping block 27. The rotating shaft 4 is fixedly connected to the clamping block 27.

The working process of the above scheme is as follows: when the mold needs to be clamped and fixed, the screw 23 drives the extrusion block 24 to move toward the mold by turning the handle 5. At this time, the telescopic rod 7 moves together with the extrusion block 24 to prevent the extrusion block 24 from rotating. When the extrusion head 3 conflicts with the mold, the extrusion rod 26 is forced to extend into the extrusion block 24, and the spring 25 is forced to retract to relieve the pressure. At this time, the clamping block 27 rotates, and one end of the clamping block 27 conflicts with the mold, thereby improving the stability of the clamping device 2.

The above scheme has the following beneficial effects: the mold is clamped and fixed at multiple angles by the clamping device 2 to prevent the mold from slipping; the extrusion rods 26 in different directions are driven by rotating different screws 23 to move the extrusion head 3 toward the mold, thereby fixing the mold and adapting to molds of different shapes; when the extrusion head 3 contacts the mold, the spring 25 is forced to retract to achieve the purpose of unloading the force to prevent damage to the mold; when the extrusion head 3 contacts the mold, the extrusion rod 26 is pressed down to cause the clamping block 27 to rotate to resist the mold, thereby further improving the clamping stability of the mold.

Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
