一. Electric car fender injection mold
1.The technical core of fender mold
Precise parting surface design:
In our electric car fender injection mold, we fully consider the machining processability of the moving and fixed mold core, as well as the reasonable arrangement of the latent gate and the location of the sprue system. Through accurate calculation and simulation analysis, the optimal parting surface is set to ensure that during the injection process, the plastic can fill the cavity evenly and smoothly, which will not affect the dimensional accuracy and appearance of the plastic part, avoiding the generation of flying edges, and allowing the plastic part to remain completely in the moving mold for the subsequent ejection operation.
2.Optimized pouring system:
With the help of advanced Moldflow software for flow analysis, the optimal number and position of latent gates are precisely determined. To meet the stringent requirement of not allowing the opening of sprue on the outer surface of the fender of the electric car so as not to affect the appearance. And at the end of the main flow channel and manifold, the cold material holes are carefully set up to effectively prevent the gate from being blocked by the cold material on the front surface of the molten plastic, which guarantees the continuity and stability of the injection molding process.
3.Efficient demolding mechanism:
We have designed a unique hook rod for counter-pulling, so that the sprue system can be smoothly detached from the gate sleeve. When designing the guide pillar, we strictly ensure that the moving mold core enters the fixed mold core only after the guide pillar enters the guide sleeve first, which effectively avoids the collision and damage of the molds in the process of opening and closing the molds. The whole demolding mechanism is equipped with spring ejector reset system, which ensures smooth and reliable ejector action, and greatly improves the production efficiency and product quality.
二、 the strict process of mold manufacturing
1.Selection of raw materials: The selection of raw materials undergoes strict quality testing to ensure that their chemical composition and physical properties meet the high standard requirements, providing a reliable guarantee for the subsequent processing and manufacturing.
2.Precision machining process:Using advanced CNC machining equipment and technology, each part of the mold is processed with high precision. From rough milling six sides, grinding reference, drilling and tapping, to CNC roughing and CNC finishing, each process is carried out in strict accordance with the process requirements to ensure the dimensional accuracy and surface quality of the parts.
3.Fine molding and assembly:In the process of mold matching, the size and shape of key parts are strictly checked to ensure that no interference occurs during assembly.
