Mold structure for molding housing, method for molding housing, and housing

1. A method for molding a housing having a lance, the lance having a first projection for engaging a terminal and a second projection provided at a position nearer with an end of the lance than the first projection, comprising:

providing a mold including:

a first mold including a first member having a third projection; and a second mold including:

a second member having a first concave portion into which the third projection is inserted; and

a third member configured to be moved with respect to the second member, wherein the second member defines, with the first member, a first space where the housing is adapted to be formed,

wherein the third member defines, with the first member, a second space where the first projection and the second projection are adapted to be formed; and

wherein the second member extends further than the third member;

filling a material between the first mold and the second mold; dividing the first mold and the second mold;

displacing the third member with respect to the second member, so that the lance is bent, by urged from the third member at the second projection, into a space where the third projection of the first member has occupied before the dividing; and

separating the housing from the second member in a state that the lance is bent into the space.

2. The method as set forth in claim 1 , wherein:

the third member has a first part configured to form the first projection with the first member and a second part configured to form the second projection with the first member,

when the third member is displaced with respect to the second member, the second part urges the second projection so that the first part is allowed to be separated from the first projection.
