高职院校塑料模具设计与制造课程思政生态建设与研究

With the comprehensive advancement of the fundamental education task of moral education, the curriculum ideological and political construction has become an important way for higher vocational colleges to implement the concept of three-complete education and the task of moral education. Higher vocational colleges should continue to promote the deep integration of professional course teaching and ideological and political elements, so as to build a full, full and all-round ideological and political education ecological environment for students. Taking the course of Plastic Mold Design and Manufacturing in higher vocational colleges as an example, this paper proposes the strategy of ideological and political ecological construction of Plastic Mold Design and Manufacturing course by analyzing the construction plan of ideological and political resource system of Plastic Mold Design and Manufacturing course, and then integrates value shaping, knowledge imparts and skills training to comprehensively improve the teaching quality and effect of the course.

Optimization of Trapezoidal Runner in Plastic Molding Based on MATLAB

The runner design is an important parts in plastic molding design. Its shape and dimensions have special effects on the molten plastic’s pressure, hot loss, injection speed, etc. At present, trapezoidal runner is used widely for better fluidity and lower assembly precision relatively compared with the circular runner. This paper uses the Fminsearch function of MATLAB and constructs an objective function based on the minimum length of the perimeter of the trapezoidal runner to optimize the trapezoidal runner section. The conclusion of this paper is that the perimeter of the trapezoidal runner is the shortest one when a equals c (shown as Fig.1), as well as the obtuse angle between a and c equals 120o. At this conditions, the volume of the molten plastic that flows through the runner section is maximum when the trapezoidal runner section area is given. The optimization results in the plastic mould design can used as the size or the constraints to drive the runner section in 3D CAD/CAM software, which can help the designer to get the trapezoidal runner section easily and quickly.

Automatic Side-Cores Construction in Injection Plastic Mold Design for Free-Form NURBS Surface Models

In computer-aided design for moldings, automatic generation of side-cores is a crucial design task that has an influence on the entire mold structure and manufacturing cost. This paper proposes a synthetic approach for creating the side-cores of free-form NURBS surface models. Based on the geometric properties of entities, surfaces of undercut features which are molded for side-cores are identified. After determining the withdrawal directions for each group of undercut’s surface features, the number of side-cores is optimized. The heads and the bodies of side-cores are finally obtained through the combination of the Boolean operation and 3D oriented extrusion. The algorithm is efficiently for both protruded and indented portions of undercut features. A complex industrial part is used to demonstrate the performance and robustness of the proposed algorithm. Since the approach is generic in nature, it is easy to be applied to any complex geometry in 3D mold design.

An extension of fuzzy TOPSIS approach based on centroid-index ranking method

The last few decades have seen a large number of methods for ranking fuzzy numbers; centroid-index based approaches are the most commonly used among them. However, there are some weaknesses associated with these centroid-indices. Therefore, this paper reviews several fuzzy numbers ranking methods based on centroid-indices and proposes a new centroid-index ranking method that is capable of effectively ranking various types of fuzzy numbers. The proposed centroid-index ranking method uses fuzzy TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) to solve multi-criteria decision making (MCDM) problems, where triangular fuzzy numbers express the ratings of each alternative and importance weight of each criterion. To avoid complicated calculations of fuzzy numbers, the normalized weighted ratings are defuzzified into crisp values to simplify the calculations of distances from each alternative to the ideal and to the negative ideal solutions. A closeness coefficient is defined to determine the ranking order of alternatives. The proposed method is applied to a parting surface evaluation and selection problem in plastic mold design, demonstrating its applicability and computational process. Key words: Ranking fuzzy numbers, centroid index, fuzzy TOPSIS, parting surface.
