Problems solved by technology

However, if an oil-based release agent is poured into a hollow tube in a high-temperature state, a new problem arises: the release agent that comes into contact with the surface of the hollow tube is released earlier than the release agent that flows in the center of the tube. When heated, the heating state of the release agent tends to become unbalanced, and the properties such as the viscosity of the oil-based release agent tend to change
[0006] If the metal powder layer is irradiated with a laser beam at an equal scanning interval and the scanning speed is adjusted and melted and solidified to form a low-density region composed of continuous fine pores, there will be a continuity of pores in places where the layer thickness is thicker. Sex prone to uneven tendencies
Therefore, if the layer thickness of the low-density region is increased, it will be difficult to control the inflow rate of the release agent, and unevenness will be observed in the seepage of the release agent.
In addition, in order to improve the manufacturing efficiency of the mold itself, there is a problem that the layer thickness of the molten and solidified mold part needs to be reduced.

Abstract

[Problem] To provide a mold, a molding system, and a mold manufacturing method which make it possible to easily and effectively spread mold release components of a mold release agent onto an inner surface of a mold without degrading the mold release agent, even with oil-based mold release agents, and which can achieve high manufacturing efficiency. [Solution] A pair of molds for molding a molded product in a gap therebetween is caused to be provided with a liquid path portion and a liquid infiltration layer configured by melting and solidifying metal powders, and a mold release agent is caused to be infiltrated into the gap. Specifically, the liquid infiltration layer is caused to be a thin layer having, at a high density, a liquid infiltration tube which is communicated with the molded surface and has a minute diameter. The liquid path portion is caused to have a 3D mesh structure having a meshed thin shaft, and is arranged along the liquid infiltration layer. The mold release agent is distributed while being in contact with the 3D mesh structure, thereby exerting such an advantageous effect that the mold release agent is not heated unevenly, and deterioration thereof is suppressed. When a form is adopted in which melting and solidifying are not performed with an axial direction of the thin shaft horizontal, this is preferable because easy melting and solidifying are achieved without breaking the thin shaft.

Description

technical field [0001] The present invention relates to a mold capable of suppressing the amount of the mold release agent used even if it is an oil-based mold release agent, and wherein the mold release component of the mold release agent is easily and effectively spread on the inner surface of the mold. Moreover, it relates to the molding system which can suppress the usage-amount of a release agent and shorten molding work by having the said mold. Moreover, it also relates to the mold manufacturing method which can manufacture the mold which can make the surface of a mold easy to infiltrate a mold release agent with high manufacturing efficiency. Background technique [0002] The mold is used as a frame for forming a resin molded product or a metal molded product. Conventionally, in order to allow the molded product to be released from the mold smoothly, a mold release agent was sprayed on the inner surface of the mold every time the molded product was cast, and the mold...
