Abstract
Official abstract text for this publication.
A cavity includes a first cavity portion, and a second cavity portion that is formed between the first cavity portion and a runner and that corresponds to a baseboard. There is adopted a configuration in which a foamed admixture is supplied to the first cavity portion via the second cavity portion upon being supplied to the cavity via the runner. A collision portion with which the foamed admixture supplied to the cavity can collide before reaching the first cavity portion is formed at the second cavity portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A core molding device that molds a core including at least one core body and a baseboard, the core molding device comprising: a molding die that has a cavity complementary to the core, and a runner communicating with the cavity; and a material supply unit that supplies a foamed admixture to the runner of the molding die, wherein the cavity includes at least one first cavity portion corresponding to the at least one core body, and a second cavity portion that is formed between the at least one first cavity portion and the runner and that corresponds to the baseboard, the foamed admixture is supplied to the at least one first cavity portion via the second cavity portion upon being supplied to the second cavity portion via the runner, at least one collision portion with which the foamed admixture supplied to the cavity is configured to collide before reaching the at least one first cavity portion is formed at the second cavity portion, the at least one collision portion is formed such that the foamed admixture that has collided with the at least one collision portion bounces back toward the discharge port of the runner, the at least one collision portion has an opposite surface facing the discharge port of the runner, and the opposite surface is recessed in a direction away from the discharge port of the runner. 2. A core molding device that molds a core including at least one core body and a baseboard, the core molding device comprising: a molding die that has a cavity complementary to the core, and a runner communicating with the cavity; and a material supply unit that supplies a foamed admixture to the runner of the molding die, wherein the cavity includes at least one first cavity portion corresponding to the at least one core body, and a second cavity portion that is formed between the at least one first cavity portion and the runner and that corresponds to the baseboard, the foamed admixture is supplied to the at least one first cavity portion via the second cavity portion upon being supplied to the second cavity portion via the runner, at least one collision portion with which the foamed admixture supplied to the cavity is configured to collide before reaching the at least one first cavity portion is formed at the second cavity portion, the at least one collision portion includes a fixed die side collision portion and a movable die side collision portion, and the fixed die side collision portion and the movable die side collision portion are butted against each other.
