The whole process of UG plastic mold design, it is recommended to collect

1. Drawing requirements (standard format)

All drawings that need to be printed are in the "STD" printing format, and the drawing requirements for each drawing are described as follows:

(1). Ranking Chart

1. Use the ranking frame (PW2X40; PWA0; PWA1) and the ranking icon to note the format.

2. Express the parting surface clearly, the main mosaic structure, runner gate and mold base type.

3. Indicate the size and position of the mouth and the top rod hole pair and the screw.

4. Indicate the maximum size of the product positioning reference, the distance between the glue position and the material edge, the distance from the bottom of the material, the outer size of the large row, the maximum size of the front and rear mold materials, and the distance between each product and the minimum ejection stroke must be clearly expressed when multiple products are produced in a set of molds .

5. Indicate the main dimensions, total height, ejection stroke, size and depth of opening of the mold pit.

6. Mark the base angle of the front mold in the lower right corner of the length of the mold base
   

The back mold is at the lower left corner of the length of the mold base

7. Mark the size and position of the slingshot hole and hide it into the depth of the B plate.

8. Add □ for product positioning, add () for all reference dimensions.

9. The front inner mold is flat with the A plate, and the rear inner mold is 0.5 mm higher than the B plate.

10. The length of the tie rod should be calculated for the fine nozzle die.

11. The product must and can only be mirrored once, after which it can only be rotated and moved for each copy, and no mirroring is allowed. The stereo angle of view must not be mirrored.

12. The mold has a stop and a zero-out stop drawing and an open block diagram that require the mold factory to open the frame, and A4 printing.

13. Update the ranking. When one of the following situations occurs, the ranking needs to be updated in time: A. Check the mold blank material list.

B. The design department comes to the official blueprint or revise the plan.

C. Design changes.

14. After the official ranking is issued, the tube and steel bills will be issued immediately.

(2) Assembly drawing

1. Use assembly drawing frame (ZP2XA0; ZPA0; ZPA1) and assembly icon annotation format

2. The main consideration is to transport water and support the head.

3. Express all the structure of the mold clearly, and use a partial enlarged sectional view if necessary.

4. The gate must have an enlarged view of the part.

5. There must be a schedule.

6. Get out the parts list in time.

(3) Thimble diagram

1. Use part drawing frame (LJA0, A1, A2, A3, A4) and part drawing standard format (LJ, LJJ).

2. The line of the glue position (product, runner gate) part is indicated by No. 149 color, and the pen width is 0.05.

3. The base angle must be marked.

4. Call the AL-LXY toolbar to indicate thimble.

5. The thimble drawing should include all thread cutting and threading holes, and the size of the pin holes.

6. The supporting thimble must have a cross-sectional diagram to express the dimensions of the supporting position.

7. Sometimes in order to express clearly, it is necessary to print and mark separately, and at the same time, there must be a total thimble, tube, insert hole, thread cutting hole, oblique top straight, top picture

8. Water transportation must be considered and not contradictory. .

(4) Line cut drawing

1) Use part drawing frame (LJA0, A1, A2, A3, A4) and part drawing standard format (LJ, LJJ).

2) The line of the glue position (product, runner gate) is represented by color No. 149, and the pen width is 0.05.

3) The base angle must be marked.

4) The oblique top line cutting adopts a uniform marking format. 5) It is clearly stated whether to cut the inner mold or the insert.

6. When the mold material in the pool is cut together with the mold embryo, mark the center as the mold embryo center. When the inner mold is cut separately, the center of the mark is the center of the inner mold material; when the current mold or the back mold has more than one inner mold material for line cutting, it should be loaded into the A or B board and then line cut, and the center of the mark is the center of the mold base .

(5) Parts drawing

1. Use part drawing frame (LJA0, A1, A2, A3, A4) and part drawing standard format (LJ, LJJ)

2. Express all structures, standardize all the required dimensions of the addition.

3. If there is a base angle and water transport, the base angle and water transport must be drawn.

4. The diagonal top and the straight top head are drawn by the parting surface or the product zero line (to be specified), and at the same time, mark one to refer to the total length.

5. Note that the drawings are drawn in parallel, with large pieces first and small pieces second.

(6) Exploded view

1) Use part drawing frame (LJA0, A1, A2, A3, A4) and standard format of part drawing (LJ, LJJ)

2) The base angle must be marked.

3) Mark the outer dimensions and the distance between the main plane of the front and rear molds and the zero line of the product.

(6) Parting diagram (3D)

1) The product positioning must be exactly the same as the ranking chart.

2) It is required to make a runner to fill the bone and column positions.

3) Due to the rotten picture, the parting surface cannot be transferred to the mold first within the required time.

4) When there is a front mold row position, pay attention to the mating surface of the row position slope and the A plate slope to avoid 0.5mm clearance.

▲At the same time, it is necessary to pay attention to the requirements for map modification proposed by other departments:

a>. Listen with an open mind and determine whether it is desirable. Be cautious when changing the map.

b>The design department must be cautious when making changes to the drawings. Check carefully to see if the changes are reasonable. When problems are found, they should be dealt with quickly and communicated in time. Any changes to the drawings must be signed and confirmed by the design department and recorded with the change statistics table. Changes to drawings. 2. Drawing management and progress control

(1) Internal drawing management

1. Material list: Put it in the material list folder according to the model number.

2. Inner mold material list of mold base: Put it in the material order folder by date.

3. Models: Put them in each folder one by one according to the product name and the order of layout. The models of each set of models are as follows:

Ranking diagram→exploded diagram→assembly diagram→thimble diagram→line cutting diagram→part diagram, etc.

4. Product 2D assembly drawing: put it in the product assembly drawing folder (including assembly drawing, color drawing, mold construction sheet).

5. Internal data: in the data folder (put design standards, management plans, etc.).

6. Empty table: placed next to the printer.

7. The layout schedule and schedule are placed in a folder.

Precautions:

1. The bill of materials must be clearly filled out: the mold number, mold name, date, maker, and copper material ordered must indicate what material is used and whether it is CNC used. Check carefully after ordering.

2. Write clearly your name, date, drawing name version, number of sheets on the drawing receipt.

3. The material list and drawing receipt are not allowed to be punched. The drawing receipt is bound together with the upper right corner of the receipt and the upper left corner of the drawing when binding.

At the same time, all drawings sent to the workshop must be signed by the team leader or supervisor, and white drawings are not allowed to the workshop.

three. Computer graphics management

One﹑

Unified and unified use of custom program menus (standard parts menu and new Tools menu), call standard blocks (such as mold base, thimble, screw, slingshot, schedule, etc.), call frame in M005\f\tk uniformly And the attached print format and label format.

2. The storage location of drawing files is managed in a unified way. Each drawing file is placed on the D: disk of the computer. The directory is the abbreviation of the initial letter of the designer's name. (For example: Philip is D:\flp ; Nokia D:\njy)

3. Naming and placement of drawing files

1>The mold drawing file is named: XX XXX ―― name

Year serial number name

The names in the naming of the mold drawing files are shown in Table 1

(Such as: 01234 - CDM indicates that the name of the 234th mold set in 2001 is CD door)

The part drawing is named: assembly, ranking-CDM.dwg

Row position-HW.dwg

Inclined roof-XD.dwg

Shovel Chicken-CJ.dwg

Thimble――――― DZ.dwg

2>. Placement of drawing files. If the example listed above is a CD206 image file drawn by Philip, then the file on Philip’s computer

D:\flp\CD206\01234 –CDm\CDM.dwg

\HW1.dwg

\ XD.dwg

\CJ.dwg

It is recommended that all the drawing files be in one drawing file, i.e. the row position, diagonal top and other drawings are all merged in CDM.dwg.

3> The drawing file placement of Pro\E is consistent with the above requirements (placed in the same directory).

Place the Pro\E drawing file in the example above in D:\flp\CD206\01234- CDM\ 4. Place the public drawing file

1). The common image files are currently placed uniformly in MO5\f\Desigm\Product Model\The old and new documents are distinguished by the date directory name.

Example: The image file of MO5\f\Desigm\CD206\010720\ was placed on July 20, 2001.

2).CNC igs, parting drawing and Pro/E drawing are unified in MO5\f\CNC\product model\mold name\. (E.g.: MO5\f\CNC\CD206\01234 -CDM\CORE.igs... )

3). After each model is completely completed, the supervisor will arrange all the graphics files of that model to MO5\f\data backup\product model\.

For example: MO5\f\Data Backup\CD206\01234—All the pictures of CDM\CD door.

After each model of product is put into production: All mold drawings of this model must be carved into 2 CDs and saved. The relevant drawings in the designer’s computer can be deleted by the supervisor after 3 months of production. The computer drawings are not allowed to be deleted.
