Abstract

Official abstract text for this publication.

Provided is a method for manufacturing a mold used in an injection molding device. The manufacturing method includes: a first step of shaping a stacked body as a part of the mold by discharging a shaping material to stack layers on a base plate; and a second step of manufacturing the mold including a mold base, the base plate, and the stacked body by incorporating the base plate on which the stacked body is shaped inside an opening provided in the mold base.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for manufacturing a mold used in an injection molding device, the method for manufacturing a mold comprising: a first step of shaping a stacked body as a part of the mold by discharging a shaping material from a three-dimensional shaping device to stack layers on a base plate having a plurality of through holes, wherein communication holes communicating with at least one of the through holes are formed in the stacked body after the layers are stacked; and a second step of manufacturing the mold to include a mold base, the base plate, and the stacked body by incorporating the base plate on which the stacked body is shaped inside an opening provided in the mold base. 2. The method for manufacturing a mold according to claim 1 , wherein the stacked body shaped in the first step has a cavity. 3. The method for manufacturing a mold according to claim 2 , wherein in the first step, the stacked body having the cavity is shaped by cutting after the layers are stacked. 4. The method for manufacturing a mold according to claim 2 , wherein the plurality of through holes are defined in a surface on which the layers are stacked, and the stacked body shaped in the first step is formed with the communication holes communicating with the at least one through hole through the cavity. 5. The method for manufacturing a mold according to claim 1 , wherein the base plate on which the stacked body is shaped in the first step is further provided with a concave portion in a surface on which the layers are stacked. 6. The method for manufacturing a mold according to claim 1 , wherein the base plate on which the stacked body is shaped in the first step has a shape that fits into the opening of the mold base. 7. The method for manufacturing a mold according to claim 1 , wherein the shaping material used in the first step for shaping the stacked body has a resin as a main component. 8. The method for manufacturing a mold according to claim 1 , wherein a part of the shaping material enters the through holes, the through holes in turn exerting an anchoring effect to the stacked body. 9. The method for manufacturing a mold according to claim 1 , wherein the mold is configured to be attached to the injection molding device such that an ejector pin is inserted into the communication holes.
