Example explanation of continuous mold design standards for automotive hardware!

1.In the continuous mold, the initial test line position must ensure that the guide hole, step distance knife gap, and side blade false detection gap are punched out at the first station;

2.After the initial testing line is set up, it must be copied to all workstations according to the step spacing to ensure that there are no unilateral punching, cutting, or forming situations;

3. The minimum distance between the initial testing line and the first sequence punching hole cannot be less than 5MM (as shown in the following figure)

Template Design Standards

1. Board splitting principle: In order to facilitate processing and mold repair cost control, each cutting and punching template adopts a separate, multi block structure; To save materials, a multi piece splicing structure can be used. If the mold structure allows, there is no longer a requirement for hard material pads. For those with punched holes, hard material pads can be added locally.

2. Template requirements: Generally, DC53 steel is used, and the template thickness is taken according to the thickness (T) of the stamping material

3. Blade sharpening amount 3mm ≤ T ≤ 3 times the material thickness

A=1 degree, unless otherwise specified by the customer.

4. Template positioning and fixing requirements:

Screws: Generally, M10 or more screws are selected, with a minimum of two or more;

Joint sales: Select screws with a size of at least 10 in diameter;

Whether to add tooth extraction depends on customer requirements. For customers with specific appearance requirements, internal teeth or tooth extraction must be added for easy assembly and disassembly.

To ensure the amount of sharpening, the screw countersunk hole should have a minimum height of 5mm from the template surface to the screw head.

Screw hole diameter edge L ≥ 5mm; Special can achieve 3.0

The minimum edge margin L1 is ≥ 8mm.

5. Blade templates with 3D profiles: The principle is to reduce the amount of CNC machining and simplify it into simple flat machining, unless otherwise specified by the customer. Or reduce the bias by 2-3 times for rough machining
