Abstract
A core molding method is a method of molding a core using a metal mold that is pressure-fed with mulled sand, and includes heating the metal mold such that the temperature of the metal mold reaches a temperature higher than a predetermined baking temperature, pressure-feeding the heated metal mold with the mulled sand, holding the temperature of the metal mold having been pressure-fed with the mulled sand at the baking temperature, and removing the core from the metal mold after the holding.
Claims10
A core molding method of molding a core using a metal mold pressure-fed with mulled sand, the method comprising:
- heating the metal mold such that a temperature of the metal mold reaches a temperature higher than a predetermined baking temperature;
- pressure-feeding the heated metal mold with the mulled sand;
- holding the temperature of the metal mold having been pressure-fed with the mulled sand at the baking temperature;
- and
- removing the core from the metal mold after the holding.
A core molding device for molding a core using a metal mold pressure-fed with mulled sand, the device comprising:
- the metal mold for baking the mulled sand;
- a pressure-feeding device configured to pressure-feed the mulled sand into the metal mold;
- a mold heat controller configured to control a temperature of the metal mold;
- a mold temperature sensor configured to measure the temperature of the metal mold;
- and
- a control unit connected to the pressure-feeding device, the mold heat controller, and the mold temperature sensor, wherein
- the control unit is configured to execute
- heating the metal mold using the mold heat controller such that the temperature of the metal mold reaches a temperature higher than a predetermined baking temperature,
- pressure-feeding the mulled sand into the heated metal mold using the pressure-feeding device,
- holding the temperature of the metal mold having been pressure-fed with the mulled sand at the baking temperature using the mold heat controller and the mold temperature sensor, and
- removing the core from the metal mold after the holding.
