Abstract

The invention relates to a method for designing a conformal cooling channel of an injection mold based on additive manufacturing technology, including designing the main structure of the mold, designing a core and cavity with a conformal cooling channel, and simulating and checking whether the design of the conformal cooling channel is reasonable three phases. The path of the conformal cooling channel provided by the present invention is completely based on the surface features of the core or cavity, or in other words, is completely based on the surface features of the plastic part. Compared with the traditional straight-through cooling water channel and baffle cooling water channel, the average distance between the cooling water channel and the plastic parts is closer, the cooling effect is better, and the cooling area is more uniform, which can effectively prevent the plastic parts from warping caused by uneven cooling. out of shape.

Description

technical field [0001] The invention relates to the technical field of injection mold design, in particular to a method for designing a conformal cooling channel of an injection mold based on additive manufacturing technology. Background technique [0002] The traditional mold design method is to design the dimensions of the mold, the number and location of the gates, the ejection mechanism, the shape and location of the cooling water channel, and then determine the part drawings of each part and the general assembly drawing of the mold based on experience, and finally process the parts , assembly, trial mode. During the mold trial process, if the plastic part cannot be made, the mold needs to be repaired; if the plastic part can be made, the size of the plastic part should be measured, if the size does not meet the requirements, the mold will be repaired again, and so on until the plastic part until the dimensions meet the requirements. During the mold trial process, the ...
