Die Casting Mold Design

What Is Die Casting Mold Design?

Die casting die design refers to the design and manufacture of dies used to inject molten metal alloys into the die cavity to form the desired part shape in order to produce die casting parts. These molds usually consist of two main parts: the upper mold and the lower mold. During die casting, molten metal is injected into these molds and the formed parts are removed after cooling and solidifying.

The main goal of die casting mold design is to ensure the production of high quality, accurate size and accurate shape of die casting parts.

Factors To Be Considered In Die Casting Mold Design

01 Part Design Analysis

Before designing the mold, the design of the required die casting part needs to be analyzed. Understand the geometry, wall thickness, holes, slots, chamferes and other details of the part in order to properly design the mold cavity.

02 Mold Material Selection

Select the appropriate mold material, usually a special steel with good wear resistance, heat resistance and corrosion resistance. The choice of die material will affect die life and part quality.

03 Cavity Design

Based on the geometry of the part, design the cavity of the upper and lower die. Taking into account the shrinkage rate of the part and the expansion coefficient of the die material, it is ensured that the final part size meets the requirements.

04 Cooling System Design

The integrated cooling system in the mold is used to control the temperature of the mold surface, accelerate the solidification of the metal and reduce deformation. An optimized cooling system increases production efficiency and part quality.

05 Gating System Design

Design the metal injection system, including sprue, nozzle and overflow system, to ensure uniform metal injection into the mold cavity and prevent the entry of gases and impurities.

06 Exhaust System Design

Design suitable exhaust channels to ensure that the molten metal can discharge gas smoothly during the injection process and avoid the formation of pores. Die separation mechanism: The mechanism for separating the upper and lower die is designed so that it can be easily removed from the die after the part is formed.

07 Surface Treatment

Considering the appearance and surface quality requirements of parts, design appropriate mold surface treatment methods, such as sandblasting, electroplating, etc.

08 Size Control

Taking into account the mold cavity shape and shrinkage rate and other factors, the size of the mold cavity is properly adjusted to ensure that the size of the final molding part is accurate.

09 Mold Assembly And Commissioning

The upper and lower die are assembled on the die casting machine and commissioning is performed to ensure that the metal can be smoothly injected into the mold cavity and formed.

Our Factory And Facilities

3E owns high precision 3-, 4- and 5-axis imported machines which allow us to achieve tight tolerances. We have also invested in a material tester, so that we can verify the materials we use and make sure they are the correct ones for each project. And we can quickly get measurement results from our automotive coordinate measuring machine (CMM).
