Mold with shape follow-up temperature control pipeline and manufacturing method thereof

Abstract

The invention provides a mold with a shape follow-up temperature control pipeline and a manufacturing method thereof. The manufacturing method comprises the steps that 1, the temperature distribution and change of the mold during cooling are simulated through computer-aided engineering; 2, a mold bottleneck position which is slowest in heat dissipation is calculated; and 3, according to the size dimension, the geometrical shape and the precise requirement condition of the position, the shape follow-up temperature control pipeline is manufactured in the mold by using the processing technology, and the shape of the shape follow-up temperature control pipeline is attached to the profile of the surface of the mold. According to the mold with the shape follow-up temperature control pipeline, a molded product can be quickly and uniformly cooled.

Description

technical field [0001] The present invention relates to a mold, in particular to a mold with a built-in complex conformal temperature control pipeline and a method for making it by direct metal laser sintering, diffuse welding, copper welding and thermal spraying techniques. Background technique [0002] Molds are usually used in high-temperature environments, such as die-casting, injection molding, and blow molding. Keeping the mold at an appropriate temperature can not only prolong the life of the mold, but also improve production efficiency and shorten the cycle time of product molding. Therefore, it is necessary to use control The temperature system maintains the mold temperature or takes away the heat of the molten material. The temperature control system generally uses media such as water, oil or steam to conduct heat conduction when the pipeline in the mold flows, so as to reduce or increase the temperature of the mold. The traditional manufacturing of temperature-co...

Problems solved by technology

The traditional manufacturing of temperature-controlled pipes relies on drilling or other traditional processing methods. However, this method can only produce straight pipes, and cannot manufacture complex temperature-controlled pipes that are close to the surface contour of the mold, and the drill bit may be broken when drilling long pipes, making the The entire mold is unusable

In addition, the distance between the temperature control pipe and the mold wall manufactured by the existing method is not uniform, which further leads to defects such as long cooling time of the finished product, formation of internal stress and warping of the finished product
