Molding method of cooling system of rapid heating die

Abstract

A forming method for a cooling system of a rapid heating mold comprises: preparing a solid cooling waterway object (30) of a default cooling waterway, the solid cooling waterway object (30) comprising multiple interconnected attachment portions (31) and multiple subbranch portions (32); placing the solid cooling waterway object (30) into a container (40) provided with a perfusion groove (41), and the attaching the attachment portions (31) onto a groove bottom surface (411) of the perfusion groove (41); preparing a perfusion material, and perfusing the perfusion material into the perfusion groove (41) of the container (40) to form a mold fixing layer (50) of the solid cooling waterway object (30) after cooling; and taking out the mold fixing layer (50), heating the mold fixing layer (50), enabling the solid cooling waterway object (30) to be in a gas state or a liquid state, and discharging the object in the gas state or the liquid state, so as to form a cooling waterway (52) corresponding to the solid cooling waterway object (30). Accordingly, a cooling waterway in any form can be formed on the mold upon needs, and the effects that the cooling waterway is easy to treat and the heat dissipation temperature of the mold is uniform are achieved.

Description

technical field [0001] The invention relates to a rapid heating mold, in particular to a cooling system molding method for a rapid heating mold. Background technique [0002] Generally, when the mold is used in plastic injection molding, aluminum alloy casting, magnesium alloy casting and other processing operations, the rapid heating system on it can improve the production quality of the mold processing and reduce the mold production cycle. [0003] For example, when the mold is used in plastic injection molding, in order to make the plastic melt for molding smoothly injected into the sprue of the mold, maintain a stable flow and avoid premature cooling of the plastic melt, so before the mold is closed and injected , Through the rapid heating system, the male mold or the female mold is preheated to a predetermined temperature, so that the plastic melt can flow into the mold cavity reliably and smoothly, and then it is cooled and formed. [0004] Similarly, with the cooling...

Problems solved by technology

[0005] Because the mold fixing layer 11 and the mold layer 12 of the upper mold 10 are all made of steel, and the mold fixing layer 11 is formed first, and then the mold fixing layer 11 is processed with the cooling water channel 111, therefore, the processing is very Difficult, and cannot conform to the complex three-dimensional geometric shape or the mold surface 121 of the mold layer 12 that is a free-form surface, so that the cooling water channel 111 is not easy to approach the mold surface 121 of the mold layer 12, so that the heat dissipation temperature on the surface of the upper mold 10 is not easy to be uniform
