6. The boding pad sharing method of claim 5, wherein the step of configuring the MCM to have the first die and the second die comprises:
implementing the first die comprising no option pad configured for a bonding option in the MCM.
7. The boding pad sharing method of claim 5, wherein the step of configuring the MCM to have the first die and the second die comprises:
implementing the first die comprising a processor core in the MCM.
8. The boding pad sharing method of claim 5, wherein the step of configuring the MCM to have the first die and the second die comprises:
implementing the second die utilizing a memory die having a device identification based on the bonding status of the option pad;
and the step of configuring the first die to perform the predetermined function according to the bonding status of the option pad comprises:
utilizing the first die to access the device identification and then perform the predetermined function corresponding to the device identification.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for molding using a flask unit to be incorporated in a flaskless molding machine that has a pair of pressing members for pressing molding sand, wherein the flask unit is adapted to be the flaskless molding machine for simultaneously making an upper mold and a lower mold, wherein said flask unit has two flasks for holding said molds, respectively, such that said flasks are turnable in the vertical plane while each flask approaches, and retreats from, the other one, each flask comprising a body that defines an opening in which a sand mold is to be molded and each having an inlet for introducing said molding sand into said opening, two mounting members, each integrally provided on opposite sides of each body of each flask for mounting said flasks on a pair of connecting arms that integrally connect one flask to another flask to form said flask unit so that the one flask and the other flask can be moved between a position where they are opposed to, and a position spaced apart from, each other by sliding the mounting members of each body of each flask along the connecting arms, while the bodies are supported at both their opposite sides by said connecting arms, wherein said connecting arms are arranged on a centerline of said opposite sides of said bodies of said flasks such that the connecting arms are opposed to each other, and
wherein each body or each mounting member of each flask has an engaging member for engaging an actuator outside of said flask such that a force or forces from said actuator can be transmitted to said flask, said method comprising the steps of:
moving the flasks of the flask unit toward each other from the spaced apart position to the opposed position by sliding said opposed mounting members of the body of each flask along said connecting rods of the flask unit;
defining a pair of molding spaces by inserting each pressing member into each opening of the body of said two flasks of said flask unit;
introducing molding sand into said pair of molding spaces through said inlets of said bodies;
moving said flask unit back and forth between a position where said defining step is carried out and a position where said introducing step is carried out; and
molding a half-mold in each flask of said flask unit to form a pair of half-molds by pressing said introduced molding sand with said pressing members,
wherein said molding step is carried out while said flask unit is being moved back to said defining step position.
2. The method of claim 1, including a step of moving said pair of half-molds in said flasks to a position where a core is to be fitted within each half-mold after said molding step.
3. The method of claim 1, including a step of moving said pair of half-molds in said flasks to a position where a mold formed from said pair of half-molds is removed from the flask unit.
4. The method of claim 1, wherein said defining step simultaneously defines said pair of molding spaces.
5. The method of claim 1, wherein said defining step defines one molding space and the other molding space of the pair of molding spaces at different times.
6. The method of claim 1, wherein said defining step is completed before said introducing step.
7. The method of claim 1, wherein said introducing step includes at least one additional defining step.
