Abstract
According to one embodiment, a housing is formed by using a pair of metal molds. The housing includes a first wall, second walls projecting from the first wall, and bosses projecting from the first wall. A molten material is filled into a molding space defined between the metal molds, and thereby a molded article having a shape corresponding to the housing is molded. The molded article has a plurality of first pin-receiving portions serving as the bosses, and a plurality of second pin-receiving portions projecting from the second walls. The first and the second pin-receiving portions are pushed by a plurality of ejector pins, and thereby the molded article is ejected from the metal molds.
Claims14
A method of forming a housing having a plurality of peripheral walls attached to a top wall that is positioned under components contained within the housing, the method comprising:
- preparing a pair of metal molds;
- filling a molten material into a molding space defined between the metal molds, and thereby molding a molded article having a shape corresponding to the housing, the molded article having a plurality of pin-receiving portions formed in a planar orientation and as part of a partition wall that is different than any of the plurality of peripheral walls, the partition wall being formed as an unitary piece of the housing and projecting upwardly from an internal surface of the top wall;
- and
- ejecting the molded article from the metal molds by pushing the pin-receiving portions of the molded article by a first plurality of ejector pins.
A method of forming a housing including an end wall and a plurality of peripheral walls extending from the end wall and surrounding a component, the method comprising:
- filling a molten material into a molding space defined between a plurality of metal molds to create a molded article having a shape corresponding to the housing, the molded article including a first plurality of pin-receiving portions formed in a planar orientation part of a partition wall that is surrounded by the plurality of peripheral walls, the partition wall being formed as an unitary piece of the housing and projecting upwardly from an internal surface of the end wall;
- and
- ejecting the molded article from the metal molds by pushing the first plurality of pin-receiving portions of the molded article by a plurality of ejector pins.
A method of forming a housing including a top wall and a plurality of peripheral walls extending from the top wall, the method comprising:
- filling a molten material into a molding space defined between a plurality of metal molds to create a molded article having a shape corresponding to the housing, the molded article including at least one pin-receiving portion formed as part of a partition wall surrounded by the plurality of peripheral walls, the partition wall being formed as an unitary piece of the housing and projecting upwardly from an internal surface of the top wall;
- and
- ejecting the molded article from the metal molds by pushing the at least one pin-receiving portions of the molded article by corresponding ejector pins.
