Abstract
A stackable molded part includes a runner portion that connects a plurality of parts, and a positioning portion that is formed on the runner portion, wherein the positioning portion protrudes in a shape of a column from the runner portion to at least one side in a stacking direction in which molded parts are stacked, wherein an end portion of the positioning portion of the molded part is engageable with an end portion of a positioning portion of another molded part that adjoins the molded part when these molded parts are stacked on top of each other, and wherein the positioning portion protrudes more than the plurality of parts in the stacking direction to the one side of the positioning portion.
Claims11
A stackable molded part comprising:
- a runner portion that connects a plurality of parts;
- and
- a positioning portion that is formed on the runner portion,
- wherein the positioning portion protrudes in a shape of a column from the runner portion to at least one side in a stacking direction in which molded parts are stacked,
- wherein an end portion of the positioning portion of the molded part is engageable with an end portion of a positioning portion of another molded part that adjoins the molded part when these molded parts are stacked on top of each other,
- wherein the positioning portion protrudes more than the plurality of parts in the stacking direction to the one side of the positioning portion,
- wherein a first engaging portion is formed on an outer periphery of the positioning portion, and
- wherein the first engaging portion is engageable with a second engaging portion that is formed on an inner periphery of a hole portion into which the positioning portion of the molded part is insertable, wherein the hole portion is formed in a top surface of a supporting fixture on which the molded part can be stacked and supported.
A molded part supporting structure comprising:
- a stackable molded part including a runner portion that connects a plurality of parts and a positioning portion that is formed on the runner portion, wherein the positioning portion protrudes in a shape of a column from the runner portion to at least one side in a stacking direction in which molded parts are stacked, wherein an end portion of the positioning portion of the molded part is engageable with an end portion of a positioning portion of another molded part that adjoins the molded part when these molded parts are stacked on top of each other, and wherein the positioning portion protrudes more than the plurality of parts in the stacking direction to the one side of the positioning portion;
- and
- a supporting fixture on which the molded part is stacked and supported,
- wherein the supporting fixture includes a top surface and a hole portion which is formed in the top surface and into which the positioning portion of the molded part is insertable,
- wherein a first engaging portion is formed on an outer periphery of the positioning portion, and
- wherein a second engaging portion engageable with the first engaging portion is formed on an inner periphery of the hole portion.
A molded part conveyance method for conveying a stackable molded part that is stacked on a supporting fixture, the molded part including a runner portion that connects a plurality of parts and a positioning portion that is formed on the runner portion, wherein the positioning portion protrudes in a shape of a column from the runner portion to at least one side in a stacking direction in which molded parts are stacked, wherein an end portion of the positioning portion of the molded part is engageable with an end portion of a positioning portion of another molded part that adjoins the molded part when these molded parts are stacked on top of each other, wherein the positioning portion protrudes more than the plurality of parts in the stacking direction to the one side of the positioning portion, wherein a first engaging portion is formed on an outer periphery of the positioning portion, and wherein a second engaging portion engageable with the first engaging portion is formed on an inner periphery of a hole portion into which the positioning portion of the molded part is insertable, wherein the hole portion is formed in a top surface of the supporting fixture on which the molded part can be stacked and supported, the molded part conveyance method comprising:
- inserting the positioning portion of the molded part into the hole portion formed in the top surface of the supporting fixture;
- and
- stacking the molded part on the supporting fixture.
