In the design of injection molds, the selection of the parting surface is undoubtedly a crucial aspect. Parting surfaces come in various forms, commonly including horizontal, stepped, angled, and irregular. The design of the parting surfaces directly impacts the quality of the molded parts and the smoothness of the processing. Therefore, we must carefully consider and prudently choose the parting surface. Designers at Yize Mold base their selections on the following key dimensions.
Consider whether the molded parts can be easily and smoothly ejected from the injection mold
An ideal parting surface location should ensure that the molded parts do not get stuck in the mold cavity during ejection and that the plastic parts remain on the moving mold plate side during mold separation, facilitating the design and implementation of the ejection mechanism.
Selection of the parting surface should strive to simplify the structure of the injection mold as much as possible
During the design process, we should comprehensively consider and choose parting surfaces that can make the mold structure simpler and easier to manufacture. A good parting surface can reduce production costs and improve production efficiency.
Venting of gases within the injection mold cavity is also an aspect that cannot be ignored
Gas venting mainly relies on the design of venting grooves on the parting surface. Therefore, it should be strategically placed at the end of the flowing melt. The parting surface should ensure smooth gas venting and avoid adverse effects on the quality of the molded parts.
Ensuring the quality of the molded parts is the primary premise of injection mold design
Regardless of how the parting surface is selected, it must be ensured that the quality of the mold itself and the molded parts meets the established standards. The quality of the mold is an unshakable principle in any injection mold design.
Selection of the parting surface should also fully and reasonably utilize existing equipment
During the design process, we should fully consider the compatibility between the injection mold and the equipment, and choose parting surfaces that can perfectly match the equipment to fully leverage the equipment’s performance and improve production efficiency.
