Mold design and manufacturing, what issues to pay attention to when designing high-precision plastic molds
The problems involved in the design and processing of high-precision plastic molds are a complex and critical field. When designing high-precision plastic molds, engineers need to pay attention to multiple aspects to ensure that the quality and performance of the final product meet expectations. This article will explore the key issues that need to be noted in the design and processing of high-precision plastic molds.
1. High precision plastic mold design engineers need to determine the mold structure and strictly regulate the product design process when conducting feasibility analysis on the plastic product drawings provided by customers.
This step is crucial as it directly affects the progress of subsequent work. Engineers need to complete this stage carefully and meticulously to save time on subsequent work.
2. It is also crucial to analyze the product development diagram based on precision injection mold design and prepare the required materials.
By preparing materials based on the product development diagram, efficiency and accuracy can be improved, errors can be reduced, and it is conducive to the rapid completion of design work.
When designing high-precision plastic molds, it is necessary to determine the mold opening direction and parting line position.
At the beginning of the design of each plastic product, it is necessary to determine its mold opening direction and parting line to minimize the core slider mechanism and minimize the impact of parting lines on the appearance. After determining the direction of mold opening, the design of the product should be as consistent as possible with the direction of mold opening to avoid core pulling, reduce seams, and extend the molding time.
4. Adjusting the draft angle of the mold appropriately can avoid problems such as white edges, deformation, and cracking at the top of the product.
When designing deep cavity structural products, the slope of the outer surface should be greater than that of the inner surface to ensure uniform product wall thickness, while also ensuring material strength and product opening time.
5. Different plastics have different wall thickness ranges, and exceeding these ranges can lead to problems such as prolonged cooling time and shrinkage.
Therefore, it is necessary to consider changing the product structure to address these issues. In addition, uneven wall thickness can lead to surface shrinkage, porosity, and fusion line problems. Reasonable use of reinforcing ribs can increase the stiffness of the product and reduce deformation.
In the process of designing and processing high-precision plastic molds, design engineers need to pay attention to the above issues to ensure the accuracy, efficiency, and excellent product quality of the mold design. Through meticulous planning and strict execution, potential problems can be effectively solved and the expected goals of the design can be achieved.
