When there are multiple inserts in the design of plastic injection molds, if you want to line them to cut by EDM machining, you usually line up multiple pieces of material together and then line cut by EDM works. The following are some points to pay attention to according to the situation of our factory Zhejiang Ceeto Mold Co.,Ltd.:
1. Do not exceed 200*200 for the placement material, convenient line cutting operation; 2. Distinguish between quenching material and soft material; 3. Is there any edge that can be ground directly without line cutting?
No. 1 Soft material placement
Line-cut alignment for insert material not quenched die: (Insert length. Width is greater than 10mm).
1. Insert processing principle is: first line cutting, after processing thimble. Screws. Water transport, then CNC machining;
2. Insert and insert are 2MM apart, the outer four sides of each 5MM margin;
3. Line cutting material to long. The width is not more than 200mm;
4. When one side of the length and width of the small insert is less than 10mm; Drill screws first, transport water, thimble, after CNC machining, the final line cutting, the placement according to the insert material as hard material;
5: Need to hit the benchmark code A in the upper left corner of the online cutting material as the benchmark.
No.2. Line cutting material placement with straight edge
For the line cutting alignment of the insert material is a soft mold:
1. For the insert with a straight edge, the straight edge can be placed against the edge of the line cutting material;
2. Leave 5MM line cutting margin on the other sides of the line cutting material, as shown in the figure:
3. Line-cut alignment for inserts with hard die material
1. In principle, the cutting amount between the insert and the insert should be 25~35MM, and the margin around the line cutting material should be 2~5MM;
2. For inserts with relatively high rubber level, the amount of cutting between inserts and inserts can be appropriately amplified;
3. For more special inserts, such as INS B. INSC.INSD.INS E in the sample figure, each insert;
4. Line cut material to length. The width is not more than 200mm;
5. Mark the reference code A in the upper left corner of the online cutting material.
No. 4. For inserts with three right Angle inserts (soft die)
1. For such inserts, multiple inserts can be combined to order materials, as shown in the figure, 0.5MM apart between each insert;
2. Cut out the entire irregular surface line during processing, and then cut out the insert line by line.
5. For the line cutting arrangement of the insert material is a hard mold:
1. When Z>=60mm, leave 35mm between insert and insert; 2. When Z<60mm, leave 22~25mm between the insert and the insert.
