An embodiment of the utility model provides an anchor clamps for mold processing. When the mold is machined, the clamp is used for clamping and fixing the material to be machined, and then the material to be machined is machined so as to machine the required mold.

As shown in fig. 1 and 2, the clip of the present embodiment includes: two

chassis

3, 4, and four hoist assemblies 23.

During the mold machining, the

base plates

3, 4 are placed on the support table with their top surfaces facing upwards for supporting the hoisting assembly 23 and the part 22 to be machined. The

chassis

3, 4 has a low height, a large length and a large width, and is in the shape of a flat cube. This shape may enhance the stability of the

chassis

3, 4. The height refers to the length perpendicular to the support table, and the length and width refer to the length parallel to the support table.

Two hoisting assemblies 23 are fixed on each chassis, and the hoisting assemblies 23 are used for fixing the part 22 to be processed, so that the part 22 to be processed is in a suspended state relative to the chassis.

As shown in fig. 1, the hoist assembly 23 includes: supporting blocks and hoisting

pieces

6, 10, 15 and 19.

The

support blocks

5, 12, 13, 18 are cube shaped with a bottom surface resting on a top surface of the

chassis

3, 4 to secure the

support blocks

5, 12, 13, 18 to the

chassis

3, 4. Screw holes are arranged at the top ends of the supporting

blocks

5, 12, 13 and 18.

The hoisting

pieces

6, 10, 15 and 19 are disks, and two screw holes are formed in the same radial direction of the disks. The disks are respectively placed at the top ends of the supporting

blocks

5, 12, 13 and 18, one of the screw holes of the disks is respectively opposite to the screw holes at the top ends of the supporting

blocks

5, 12, 13 and 18, and the disks can be respectively fixed at the top ends of the supporting

blocks

5, 12, 13 and 18 through the matching of the

screws

7, 11, 14 and 20 and the screw holes.

When the jig shown in fig. 1 and 2 is used, four screw holes need to be formed in the back surface 2 of the member to be processed 22. The four screw holes are preferably symmetrical in position, and for example, for the cube-shaped member to be machined 22 in fig. 2, the four screw holes are located at the four corners of the back surface 2 of the member to be machined 22. The screw holes on the back surface 2 of the part 22 to be processed are symmetrically positioned, so that the stability of fixing the part 22 to be processed can be enhanced.

As shown in fig. 2, when the back surface 2 of the member to be processed 22 is processed by using the jig, first, the screw holes of the four hoisting assemblies are aligned with the four screw holes of the back surface 2 of the member to be processed 22, and the four disks are fixed to the back surface 2 of the member to be processed 22 by the four

screws

8, 9, 16, 17 through the engagement of the

screws

8, 9, 16, 17 with the screw holes. Since the four screw holes are located at the four corners of the back surface 2 of the member to be processed 22, the circular disks are also fixed at the four corners of the back surface 2 of the member to be processed 22, respectively.

Then, the supporting

blocks

5, 12, 13, 18 of the four hoisting assemblies are placed on the

chassis

3, 4 and fixed so that the positions of the four supporting

blocks

5, 12, 13, 18 correspond to the positions of the four discs, respectively. The position correspondence means that the space between the supporting

blocks

5, 12, 13 and 18 is matched with the space between the disks, so that the screw holes at the top ends of the supporting

blocks

5, 12, 13 and 18 are respectively opposite to the idle screw holes of the corresponding disks.

Finally, the four disks are respectively fixed at the top ends of the corresponding supporting

blocks

5, 12, 13 and 18 through the matching of the

screws

7, 11, 14 and 20 and the screw holes, so that the part 22 to be processed is fixed on the

chassis

3 and 4.

In this embodiment, as shown in fig. 3, when the back surface 2 of the to-be-processed member 22 is processed, since the back surface 2 of the to-be-processed member 22 is fixed on the disk, and the disks are fixed on the top ends of the supporting

blocks

5, 12, 13, and 18, respectively, and the heights of the supporting

blocks

5, 12, 13, and 18 are greater than the thickness of the to-be-processed member 22, the to-be-processed member 22 is suspended and suspended in a suspended state with respect to the

chassis

3 and 4, and is not in contact with the

chassis

3 and 4. The height and thickness both refer to the length in a direction perpendicular to the

chassis

3, 4.

As shown in fig. 4, when the front surface 1 of the member to be processed 22 is processed by using the jig, first, the screw holes of the disks of the four hoisting assemblies are aligned with the four screw holes of the back surface 2 of the member to be processed 22, respectively, and the four disks are fixed to the back surface 2 of the member to be processed 22 by using the four

screws

8, 9, 16, 17 through the cooperation of the

screws

The four disks are then placed on the

base plates

3, 4 and fixed so that the part 22 to be machined is fixed to the

base plates

3, 4 with the front side 1 facing upwards.

In this embodiment, when the front surface 1 of the to-be-processed member 22 is processed, the back surface 2 of the to-be-processed member 22 is fixed to the disk, and the disk is fixed to the

chassis

3, 4, so that the to-be-processed member 22 is suspended in the air with respect to the

chassis

3, 4 and does not contact with the

chassis

3, 4.

Therefore, when the mold is machined by using the clamp of the embodiment, no matter the front surface 1 or the back surface 2 of the part to be machined 22 is machined, the part to be machined 22 is suspended relative to the

chassis

3 and 4 and does not contact with the

chassis

3 and 4, so that the part to be machined 22 does not need to reserve process pins. In the processing process, the step of removing the process foot is not needed, so that the deformation of the back surface 2 of the part 22 to be processed caused by a large amount of heating and residual stress is avoided, the processing quality and the production efficiency of the die are improved, the material waste is reduced, and the generation cost is reduced.

In this embodiment, the

chassis

3, 4 may be made of magnetic material, so that the

chassis

3, 4 becomes a magnetic chuck. While the support blocks 5, 12, 13, 18 and the discs are of steel, for example 738H. When the back surface 2 of the member to be processed 22 is processed by a jig, the

base plates

3, 4 and the support blocks 5, 12, 13, 18 are fixed by magnetic force. When the front surface 1 of the member to be machined 22 is machined by a jig, the

chassis

3, 4 and the disk are also fixed by magnetic force.

The magnetic fixing device has the advantages that the fixing mode is simple, the dismounting is convenient, the

chassis

3, 4, the supporting

blocks

5, 12, 13, 18 and the disc do not need to be additionally processed, and the operation is very convenient when the positions of the supporting

blocks

5, 12, 13, 18 and the disc on the

chassis

3 and 4 need to be changed.

The present embodiment has been described above with reference to fig. 1 to 4, but the above description is merely exemplary, and the present embodiment is not limited thereto. For example:

the shape of the

chassis

3, 4 may also be other than a cubic shape, which may be a disc-like structure of other shapes. For example a disc, a disc-like structure with a square, oval, polygonal, triangular, parallelogram or irregular cross-section. The cross section is a section parallel to the support table.

The support blocks 5, 12, 13, 18 may also be other than cubic in shape, and may be in the form of cylinders, columns with a cross-section of square, oval, triangular, polygonal, or parallelogram. The cross section is a section parallel to the

chassis

3, 4.

Likewise, the

sling

6, 10, 15, 19 may be other than a disc, which may be of other shapes and configurations. Such as a disk-like structure having a rectangular, square, oval, polygonal, triangular, parallelogram, or irregular cross-section. The cross section is a section parallel to the

chassis

3, 4.

The fixing of the support blocks 5, 12, 13, 18 to the

chassis

3, 4 is also not limited to magnetic fixing, but other types of fixing are used, such as: screws, snaps, and the like. Likewise, the fastening of the

sling

6, 10, 15, 19 to the

support block

5, 12, 13, 18 and of the

sling

6, 10, 15, 19 to the part 22 to be machined are not limited to screw fastening, but other types of fastening can be used.

In the example of fig. 1 to 4, the jig comprises two

chassis

3, 4, each comprising two hoist assemblies 23, but the embodiment is not limited thereto. The number of the base plates and the hoisting assemblies 23 corresponding to each base plate is determined according to the shape of the part 22 to be machined. For example, the fixture may comprise three bases, one for each hoist assembly 23, which is adapted for use with a triangular part 22 to be machined. The three corners of the part 22 to be machined can be fixed to a base plate by means of a respective lifting assembly 23, so that the part 22 to be machined is lifted relative to the base plate.

In this embodiment, as shown in fig. 3, the height of the support blocks 5, 12, 13, 18 is 10mm to 20mm greater than the thickness of the member 22 to be machined. Both the height and the thickness refer to the length perpendicular to the

chassis

3, 4. Thus, after the hoisting assembly 23 hoists the part 22 to be processed, the distance between the part 22 to be processed and the

chassis

3 and 4 is 10mm-20 mm.

During the machining of the mold, iron pieces generated from the member to be machined 22 enter the gap between the member to be machined 22 and the

chassis

3, 4. If the heights of the supporting

blocks

5, 12, 13 and 18 are too small, the distance between the part 22 to be machined and the

chassis

3 and 4 is too small (less than 10mm), which may cause iron chips to contact the machined surface of the part 22 to be machined, and may cause the product to be scratched; if the height of the support blocks 5, 12, 13, 18 is too great (greater than 20mm), on the one hand material is wasted and on the other hand unstable fixing of the part 22 to be machined results. The height of the supporting

blocks

5, 12, 13 and 18 is 10mm-20mm larger than the thickness of the part 22 to be processed, so that the product can be prevented from being scratched and the part 22 to be processed is prevented from being fixed unstably.

The processing of the mold by using the jig of the embodiment includes:

step S1: the back surface 2 of the part 22 to be processed is placed on the

chassis

3, 4 with the back surface 2 facing upward, and the back surface 2 of the part 22 to be processed is roughly processed.

Step S2: the front 1 of the part 22 to be processed is upward and is fixed on the

chassis

3 and 4 through the hoisting assembly 23, the part 22 to be processed is in a suspended state relative to the

chassis

3 and 4, and the front 1 of the part 22 to be processed is subjected to rough processing and finish processing in sequence.

Step S3: the back 2 of the part 22 to be processed is upward and fixed on the

chassis

3 and 4, and the back 2 of the part 22 to be processed is polished.

In step S1, the back surface 2 of the member to be processed 22 is first placed directly on the

base plates

3 and 4 with the back surface 2 facing upward, and the back surface 2 of the member to be processed 22 is roughly processed.

Then, eight screw holes 21 are processed at the edge of the back surface 2 of the member to be processed 22, as shown in fig. 6. These screw holes 21 are used for fixing the

sling

6, 10, 15, 19. Of the eight screw holes 21, four screw holes are located at four corners of the back surface 2 as corner screw holes for the rectangular member to be processed 22. And the other four screw holes, wherein two screw holes are positioned between the screw holes at the two corners and at the edge of the long edge of the back surface 2. The other two screw holes are positioned between the screw holes at the other two corners and the edge of the other long edge of the back surface 2 is formed into edge screw holes.

In step S2, as shown in fig. 4, first, the

sling

6, 10, 15, 19 is fixed to the back surface 2 of the member to be processed 22. The four disks are fixed at four corners of the back surface 2 of the part to be processed 22 respectively by utilizing the matching of screw holes and screw holes.

And then, turning the part 22 to be processed and the discs integrally, enabling the front surface 1 of the part 22 to be processed to face upwards, and fixing the four discs on the

chassis

3 and 4 through magnetic force, so that the front surface 1 of the part 22 to be processed faces upwards and is fixed on the

chassis

3 and 4. At this time, the disk supports the member to be machined 22, and a gap is left between the member to be machined 22 and the

base plates

3 and 4, so that the member to be machined does not contact the

base plates

3 and 4.

Next, the front surface 1 of the member to be processed 22 is subjected to rough machining and finish machining in this order.

After the front surface 1 is roughly processed, the part 22 to be processed is subjected to aging treatment and then to finish processing. The aging treatment comprises the following steps: the member 22 to be worked is left at room temperature to release its stress, and the roughly worked member 22 is deformed in this process. After the aging treatment is completed, the front surface 1 is finished, and all the processes of the front surface 1 are completed, and the finished front surface 1 is shown in fig. 7.

In step S3, the back surface 2 of the to-be-processed member 22 is fixed to the

hangers

6, 10, 15, and 19, and then the

hangers

6, 10, 15, and 19 are fixed to the support blocks 5, 12, 13, and 18, respectively, so that the back surface 2 of the to-be-processed member 22 faces upward and is fixed to the

chassis

3 and 4.

As shown in fig. 2, first, the member to be processed 22 and the disk are turned over as a whole from the state shown in fig. 4 with the back surface 2 of the member to be processed 22 facing upward.

Then, the four

support blocks

5, 12, 13, 18 are fixed to the

chassis

3, 4 so that the support blocks 5, 12, 13, 18 correspond to the four disk positions, respectively.

And the four disks are respectively fixed on the corresponding supporting

blocks

5, 12, 13 and 18 through

screws

7, 11, 14 and 20, so that the back 2 of the part 22 to be processed faces upwards and is fixed on the

chassis

3 and 4. At this time, the supporting

blocks

5, 12, 13, 18 and the disk lift the member to be machined 22, and a gap is left between the member to be machined 22 and the

chassis

3, 4, without contacting the

chassis

3, 4.

After the component 22 to be machined is fixed, first finishing of the rear side 2 is carried out. The disk is fixed to each of four corners of the back surface 2, and the four corners and the area in the vicinity thereof are referred to as a first area, and the area other than the first area of the back surface 2 is referred to as a second area. The first finishing process distributes finishing to only the second area.

After the first finishing processing is finished, the part 22 to be processed is detached from the four disks, the four supporting

blocks

5, 12, 13 and 18 and the positions of the corresponding disks are moved and fixed at the positions opposite to the four side screw holes on the back 2 of the part 22 to be processed. As shown in fig. 8, the four disks are fixed to the corresponding screw holes by

screws

8, 9, 16, and 17, respectively, so that the back surface 2 of the member to be processed 22 faces upward and is fixed to the disks. This frees up the first area of the first finishing unprocessed.

And finally, performing secondary finish machining on the first area of the back surface 2 to finish the whole machining process.

Therefore, in the processing method of the embodiment, the process foot does not need to be reserved for the part 22 to be processed, and the step of removing the process foot is not needed in the processing process, so that the deformation of the back surface 2 of the part 22 to be processed caused by a large amount of heating and residual stress is avoided, the processing quality and the production efficiency of the die are improved, the material waste is reduced, and the generation cost is reduced.
