Abstract

The invention discloses an injection mold conformal cooling channel topology generation method based on an equal cross section. Design of a conformal cooling channel is related to the appearance of aninjection product model. The two-dimensional cross section is adopted for representing the three-dimensional model exterior characters of an injection product, and the complexity degree of design ofthe conformal cooling channel is lowered. Meanwhile, by integrating injection mold cooling system design knowledge and curve offset and fairing and other algorithms, the degree of dependence on the experience of design engineers is lowered, and the design efficiency and design quality of the conformal cooling channel are improved.

Description

technical field [0001] The invention relates to the field of injection molds and conformal cooling, in particular to a method for generating topology of injection mold conformal cooling channels based on equidistant sections. Background technique [0002] With the rapid development of 3D printing technology, conformal cooling has been more and more widely used in injection molds for consumer electronics, home appliances, and auto parts. Injection mold conformal cooling channels (Conformal Cooling Channels) means that the topology of the cooling channels changes with the surface of the injection mold cavity. The cooling channel and the cavity surface always maintain a certain distance. Strong control force can achieve fast and uniform cooling. [0003] At present, the generation of conformal cooling channels mainly relies on the manual operation of design engineers. The design process is cumbersome, long-term, and depends on the experience of engineers. Improving the genera...
