Mold Indentation Is A Hollow Area Contained Inside The Crate Mould
The mold indentation is a hollow region contained inside the Crate Mould(FURNITUREMOULD) into which the molten polymer is injected and allowed to cool. When a mold tool contains more than one stamp, it is called a multi-die tool.
The core forms the interior of the molded part and can be identified as a convex part that constitutes the stamp. The core is held or located in a plate called a core plate, and the mold half containing the core assembly is referred to as the core half of the mold. Due to the shrinkage characteristics encountered when the polymer is melt cooled, the cooling mold tends to shrink onto the core and away from the cavity wall once solidified. This characteristic contraction behavior allows the mold to remain on the core during the mold opening process for ejection purposes. Since the machine ejector system is located behind the moving platen of the forming machine, the half core of the mold is typically clamped to the moving platen of the machine during use.
The cavity forms the outer or display surface of the molded part and can be identified as a concave part that constitutes the stamp. Like the core, the cavity is held or located in its own template, the name of which is the cavity plate. The remaining half of the mold containing the cavity is referred to as the cavity half and is typically clamped to the stationary platen of the molding machine in front of the injection unit. The mold feed system is usually located in the half cavity of the mold because it is close to the machine injection unit.
Since the tool designer tends to position the ejection system in the half core and position the feed system in the half cavity, it is easy to understand the effect of the tool design on the chosen configuration of the molding machine. Therefore, the most commonly encountered machine design is the online 'configuration.
