The knowledge contained within the mold is extensive, thus necessitating an introduction and explanation. Therefore, the editor will first summarize it as follows:

How to Reasonably Design Molding Structures?

What are cold rolling dies and hot rolling dies?

Since the summary above has been provided, let's now delve into the specific details. We hope this will be helpful and inspiring to all, thereby giving you a better understanding of molds.

How to reasonably design mold structures? To achieve this, the measures we can take generally include:

(1) Consider the rationality of mold guiding accuracy, the appropriateness of the cutting clearance, and whether the mold rigidity is suitable. Additionally, try to use combined molds as they are preferable.

(2) For formwork, it should have good rigidity to meet the strength requirements. Moreover, the templates should not be too thin; they should be appropriately thickened, but not overly thick.

(3) Aim for four guide pins to ensure optimal guidance and rigidity, which guarantees uniformity in the mold clearance and prevents collision.

(4) To minimize the adverse effects of press machines and other equipment on mold guide accuracy, the mold clamping should be reliable.

(5) During assembly, check the perpendicularity of the mold axis to the horizontal plane, as well as the parallelism between the top and bottom surfaces.

Cold rolled molds, which mainly include cold punching dies, wire drawing dies, stretching dies, embossing dies, thread rolling dies, rolling plates, cold heading dies, and cold extrusion dies, require high hardness, strength, toughness, and wear resistance in the steel used, along with other process performance requirements.

Hot rolled dies, which are categorized into forging, die forging, extrusion, and die casting, demand high-quality steel properties. They must ensure consistent mechanical properties across the entire cross-section, along with other specific requirements.
