Description

Technical Field

[0001] The utility model belongs to the technical field of molds, in particular to a rapid prototyping mold. Background Art

[0002] Rapid prototyping molds, also known as rapid molds, are a method of manufacturing molds through rapid prototyping technology, which can significantly shorten the mold manufacturing cycle and reduce manufacturing costs.

[0003] Molds are various molds and tools used in industry to obtain the required products by methods such as injection molding, blow molding, die-casting or forging, stamping, etc. Molds are divided into metal molds and non-metal molds according to different materials. The structure of the mold is generally divided into two parts: the movable mold and the fixed mold. In the stamping process, the sheet to be stamped is placed between the movable mold and the fixed mold, and pressure is applied to the sheet to make it plastically deformed, so as to obtain the workpiece of the required shape and size. After stamping the sheet for a long time, the mold will generate heat.

[0004] In existing rapid prototyping molds, friction will occur between the mold and the sheet during the stamping process, and the heat generated by the deformed sheet will also be transferred to the mold, causing the mold to heat up. When the mold is overheated, it will affect the structural strength of the mold, causing the mold to age faster and affecting the service life of the mold.
