The official production of automotive die-casting molds is a key link in the successful development of automotive die-casting parts, and the good design of the runnersystem is a prerequisite to ensure the normal production of automotive die-casting molds.
The design of the runner system has many factors that affect the quality of die-casting parts, especially for products with special requirements such as air tightness and surface roughness. These special requirements often become a key indicator for assessing the success of a car die-casting mold during mass production.
We have found in actual production that although there are many factors that affect the quality of special requirements for die-casting parts, the setting of the gate position is often a crucial aspect that cannot be ignored. Improper gate position setting can cause the overall scrapping of a mold or greatly reduce the life cycle of the mold.
The design of the gating system for die-casting parts needs to be carried out after analyzing the structure of the casting and determining various requirements. The general process of designing a pouring system is: selecting the position of the gate → considering the direction of guiding metal flow → dividing the number of gates → setting the shape and size of the gate → determining the cross-sectional area of the inner gate.
In the actual design of automotive die-casting molds, except for the selection of gate position being the first step to consider, the above sequence is only a rough step to consider, and the sequence is not very strict. In fact, these aspects are mutually influencing and constraining each other. When considering the latter step, it is likely that changes and adjustments will need to be made to the design already made in the previous step.
Therefore, it is necessary to comprehensively consider the specific situation and design a pouring system that meets the requirements.
