1, plastic mold embryo core crowded tight block design standards: plastic mold

1. In order to facilitate the distribution box, the mold of the long, wide size ≥ 300mm, must do compact block

2. Inner mold If you can not design baroclin, you need to put it in sketch meeting

3.C corner size according to the size of the mold surface, the minimum value of C13

4. According to the needs of mold structure and customer requirements

2, plastic mold embryo hanging hole provisions:

1. Plastic mold embryo board holes are required, 40 * 40 above plus four rings hole

2. Hanging hole size specifications, the following dimensions can lift the entire mold, the other according to the height of the plastic mold embryo itself to adjust

3 hanging hole depth requirements

4. Lifting hole not with slot, guide post holes and other interference

5. Rings holes in the plastic mold embryo should be designed to be symmetrical to each other, the same size. Ensure the mold is balanced when lifting. If the plastic mold embryo can not be done, can be taken in plastic mold embryo inlaid steel plate, column plus rings hole.

6. Design should also consider rings do not interfere with other accessories

3, back to the standard

1. Backstitch in ? 15 above the embryo embryo, two diagonal needle back in the diagonal attack.If the back needle and push plate fixed movement is four tapping. Tackling teeth on four back needles is for disassembly and assembly of the molds, since it has a sloped top.

2. back to the head size and thread size in the table below:

3. Plastic mold embryo length 1500mm and above, the need to design more than 6 needle back.

4. back to the needle tube to ensure that more than 30mm. If the tube is too long, need to avoid the air.

4, in the care division standards and scope

1 in the care division into the B plate 15 ~ 20mm, head care cup to tapping the end of the cup

2. plastic mold embryo in the diameter greater than or equal to embryo back needle.

3. Die in the following circumstances, the need to add in the care division:

① mold has a sloped top, straight top, push block and a thimble.

② mold has a second ejection structure.

③ front mold top.

④ plastic mold embryo size 3030 and above.

4 in the size of the Secretary, the size of the location design standards to avoid interference
