Efficiency Cooling Channel at Core Side Incorporating with Baffle and Bubbler System

Machine learning aided design of conformal cooling channels for injection molding

“…To precisely predict the local part temperature however, the existing theoretical models are not sufficient. First, the resulting part surface temperature cannot be derived from 𝑇 𝑚 (𝑡) in equation (1)(2)(3)(4)(5)(6)(7)(8)(9)(10) or 𝑇 𝑚𝑠𝑢𝑟𝑓 (𝑡) in equation (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15), since they mainly reflect the thermal status of the mold during an injection molding cycle. Thus, it is impossible to utilize these theoretical models for a fast and accurate prediction of the local part temperature based on a given set of cooling channel design parameters.…”

“…Nevertheless, the limitation of the conventional drilling and casting process imposes constraints in designing complex and effective cooling channels. Traditionally, the cooling system of the injection molding machine is either designed with straight cooling channels [8], or an array of cooling baffles [9]. These conventional cooling channels are not necessarily conformal to the part geometry, which results in a longer production cycle time and poor quality of the part [10].…”
