Die casting draft angle

1. Mold design

Mold design is the starting link for the draft angle of die castings. In the design phase, the requirement for draft angle needs to be determined based on the shape, size, and purpose of the parts. A reasonable draft angle can ensure that the die-casting part can smoothly detach from the mold without damaging the surface quality of the part. In mold design, the angle and position of the draft angle need to be considered, usually determined based on the demolding direction and structural characteristics of the part.

2. Die casting process

The die-casting process is a key link in achieving draft angle. During the die casting process, metal materials are injected into the mold, forming a die casting within the mold. At this point, the effect of draft angle is to reduce the friction between the part and the mold, allowing the part to smoothly detach from the mold. In order to ensure the smooth progress of the die-casting process, it is necessary to reasonably control the temperature, injection rate, and pressure parameters of the metal material.

3. Metal materials

The selection of metal materials also has a significant impact on the draft angle. Different metal materials have different thermal expansion coefficients and flowability, which can affect the calculation and implementation of draft angle. When selecting metal materials, it is necessary to consider factors such as material processing performance, mechanical properties, and thermal properties to ensure smooth production and qualified quality of the parts.

4. Mold temperature

Mold temperature is another important factor affecting the draft angle. The temperature of the mold will affect the fluidity, filling ability, and cooling speed of the metal material, thereby affecting the realization of the draft angle. In actual production, it is necessary to select the appropriate mold temperature based on the characteristics of metal materials and molds to ensure the smooth demolding of parts and production efficiency.

5. Calculation of draft angle

The calculation of draft angle is a key step in achieving a reasonable draft angle. The size of the draft angle is usually determined based on the structural characteristics of the part, the performance of the metal material, and the design parameters of the mold. When calculating the draft angle, it is necessary to consider factors such as the shrinkage rate, demolding force, and friction coefficient of the part to ensure that the part can smoothly detach from the mold without causing damage to the surface quality of the part.

6. Draft angle inspection

Draft angle inspection is an important step in ensuring smooth demolding of parts. During the production process, it is necessary to regularly inspect the draft angle of the parts to check whether they can smoothly detach from the mold. If it is found that the parts cannot be demolded smoothly or the surface quality is damaged, it is necessary to adjust the mold or modify the draft angle in a timely manner to ensure the smooth production and qualified quality of the parts.

7. Mold wear

Mold wear is an important factor affecting the realization of draft angle. As the mold usage time prolongs, the surface of the mold will gradually wear out, which will affect the demolding effect and surface quality of the parts. In order to extend the service life of the mold, it is necessary to regularly inspect and maintain the mold, promptly repair worn parts, and maintain the mold in good condition.

8. Processing allowance

Processing allowance refers to the amount of metal material reserved during the processing of a part to ensure that the size and quality of the part meet the requirements. During the die casting process, the control of machining allowance also has a certain impact on the draft angle. If the machining allowance is too large, it will cause the parts to fail to demould smoothly; If the machining allowance is too small, it will cause the size and quality of the parts to not meet the requirements. Therefore, it is necessary to reasonably control the size of the machining allowance to ensure the production efficiency and qualified quality of the parts.
