Problems solved by technology

[0010] Aiming at the above technical problems, the present invention provides an injection mold manufacturing device and method with a conformal cooling pipe. While the mold is formed by using the SLM technology based on the layered manufacturing principle, the preformed conformal cooling pipe is embedded in the mold. In the mold cavity entity, it effectively solves the problem that in the existing solution, when the pipe arrangement is complex and the diameter is small, it is easy to cause metal powder blockage, which makes it difficult to clean the powder. problem of effect

Abstract

The invention discloses a manufacturing device and method for an injection mold with a conformal cooling pipeline. At first, a part of a mold cavity entity is machined by the adoption of an SLM technology based on a layered manufacturing principle, then a semicircular groove used for containing the conformal cooling pipeline is machined in a proper position inside the mold cavity entity, after metal powder in the groove is cleaned out, the conformal cooling pipeline is placed in the groove, metal powder in the first half of the pipeline is fused through the SLM technology finally, the conformal cooling pipeline can be embedded in the mold cavity entity accordingly, ultimately the method is repeated according to the depth of a mold cavity, and multiple layers of conformal cooling pipelines can be embedded in the mold cavity entity in a layered mode. Thus, the defect that conformal cooling pipelines of a mold are directly manufactured by the adoption of the SLM technology can be overcome, the cooling pipelines with the diameter less than 6 mm can be manufactured, meanwhile it is guaranteed that inner walls of the pipelines are smooth, cooling capacity of the mold and cooling evenness of plastic injection products can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, in particular to an injection mold manufacturing device and method with a conformal cooling pipeline. Background technique [0002] In the 1990s, Selective Laser Melting (SLM) technology emerged as a new rapid prototyping (RP) technology based on the principle of layered manufacturing. It uses a variety of metal powder materials as raw materials. After selectively melting the metal powder with a high-power laser, combined with rapid cooling and solidification technology, it can obtain non-equilibrium, supersaturated solid solution and uniform and fine metallographic structure. The formed parts The relative density can reach more than 99%, and the mechanical properties are equal to or even better than forged parts. Due to the use of this technology to manufacture complex metal parts that are difficult to manufacture by traditional methods, it has been increasingly valued by experts and...
