Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a left-right continuous mold. Background Art

[0002] A progressive die, also known as a step-by-step die, is a cold stamping die that uses a strip of raw material to complete multiple stamping processes simultaneously on a die using several different stations in one stamping stroke of the press. The design of this die allows the material strip to move forward at a fixed step distance each time the stamping is completed until the entire product is completed;

[0003] In the production process of dishwasher hinges, the application of continuous molds is an efficient and stable production method. Raw materials in strip form, such as stainless steel strips, are prepared. Cutting, bending, punching and other stamping processes are carried out in sequence at multiple stations of the continuous mold to gradually process the raw materials into various parts of the dishwasher hinge. After each stamping is completed, the material strip moves according to the set distance for the next round of stamping.

[0004] After searching the prior art for "high-precision continuous mold", the announcement number is "CN211464509U". This device avoids shape deviation caused by sliding and ensures the processing quality of parts. However, during the stamping process, the temperature of the mold will increase due to contact with the material. Excessive mold temperature may cause unstable size of the stamped parts and affect the quality and precision of the processed parts.

[0005] Therefore, a left-right continuous die is proposed to solve the above problems. Utility Model Content
