Abstract
A mold battery with provisions for separating one mold member from another by both rotating away and also translating away. A mold member comprises two wheels resting on two rails and a lower roller. While the mold member is rotated to an open angle stopped by the lower roller contacting a stop surface, yet the mold member can also be translated away by rolling along the rails. When joining mold members, a freedom of movement is provided which improves the seal. One embodiment comprises parallel guidance by wheels fixed on a common axle and turning in unison. One embodiment substitutes a fixed pin for the lower roller.
Claims9
A mold battery comprising:
- a. a mold member, having generally a planar shape, having a near edge and a far edge,
- b. an axle having a near end and a far end, which is rotatably connected to said mold member, wherein the near end is near the near edge and wherein the far end is near the far edge,
- c. a first wheel having a first outside diameter, said first wheel fixed on the near end, and
- d. a second wheel having a second outside diameter, which second outside diameter is substantially equal to the first outside diameter, said second wheel fixed on the far end,
- whereby it necessarily follows that, if the near edge of the mold member is moved by rolling it on the first wheel a first distance, then the far edge moves simultaneously on the second wheel a second distance which is substantially equal to the first distance.
A mold battery comprising:
- a. a mold member, having generally a planar shape,
- b. a first wheel rotatably connected to the mold member,
- c. a second wheel rotatably connected to the mold member,
- d. a near rail, having a first top surface on which the first wheel bears,
- e. a far rail, having a second top surface on which the second wheel bears,
- f. a stop surface, and
- g. a roller rotatably attached to the mold member wherein if the planar shape of the mold member is vertical, then the roller does not contact the stop surface, and wherein if the mold member is rotated an opening angle, then the roller contacts the stop surface, wherein the opening angle ranges between 2 and 80 degrees,
- whereby if the roller contacts the stop surface, then it necessarily follows that the mold member is stopped from rotating more than the opening angle, and whereby it necessarily follows that the mold member can translate while at the opening angle.
