Application of CAE Technology in Injection Mould Design

The process of mold design is generally like this: from the user to the plastic product drawing (which may be two-dimensional or three-dimensional), the mold design engineer considers the appropriate structure according to the type, characteristics and shape of the product. That is, the plastic Pieces can be formed by using what kind of mold structure. In this process, the structural design engineer also needs to select the type, size, gate type, quantity, size, location of the runner and determine the number and size of the runner according to some specific requirements of the product. In addition to being structurally sound, the designed mold is also feasible in terms of casting and cooling systems.

Obviously, mold design is very demanding on structural design engineers. He not only has experience in structural design, but also has a lot of knowledge in molding materials and molding processes, or the success or failure of the design depends largely on the experience of the mold designer. Even though the design engineer has good experience in mold design, he still faces many new problems, because the actual product is often kaleidoscopic. Sometimes subtle changes or specific product requirements can make an existing experience unavailable, or even if available, it cannot be verified prior to actual testing. This leads to an important design-correction-redesign feature of the mold design process. How to reduce the number of cycles in the process so that the initial design achieves or approximates the combined result is of great significance in practice.

CAE analysis is an ideal tool to solve the above problems. The reason is that the tool is based on a relatively accurate mathematical model and thus can approximate the results of actual production practice. In addition, the computational speed allows multiple gating and cooling systems to be executed before the actual test. Evaluate until optimization, thereby shortening design and manufacturing cycles and improving quality.
