Abstract

A mold system, mold opening apparatus, and method. The mold opening apparatus can include a mold carrier member, a vertical movement mechanism, a rotational movement mechanism, and one or more mold engagement mechanisms.

First claim

What is claimed is:

1 . A mold opening apparatus, comprising:
a mold carrier member, wherein the mold carrier member comprises: a first side, a second side opposite the first side; a front side, and a back side opposite the front side; a vertical movement mechanism coupled to the mold carrier member; a rotational movement mechanism coupled to the back side of the mold carrier member and adapted to rotate the mold carrier about a fixed axis with a synchronized angular displacement, wherein the rotational movement mechanism comprises a rotational locking member for inhibiting rotational movement during vertical displacement; and two or more mold engagement mechanisms, wherein the two or more mold engagement mechanisms are coupled to at least a portion of the mold carrier member, wherein the mold engagement mechanisms comprise first and second side engagement arms and a front end engagement arm arranged at different angular positions on the mold carrier member, such that the mold parts engage and disengage mold parts in a sequential manner during rotational displacement.

2 . The mold opening apparatus according of claim 1 , wherein the two or more mold engagement mechanisms comprise first and second mold side engagement mechanisms and a mold front end engagement mechanism, wherein the first mold side engagement mechanism is coupled to the first side of the mold carrier member, and the second mold side engagement mechanism is coupled to the second side of the mold carrier member, and wherein the mold front end engagement member is coupled to the front side of the mold carrier member.

3 . The mold opening apparatus of claim 2 , wherein the first and second mold side engagement mechanisms are adapted to horizontally shift towards and away from the respective first and second sides of the mold carrier member.

4 . The mold opening apparatus of claim 2 , wherein each of the first and second mold side engagement mechanisms is adapted to vertically shift towards and away from the mold carrier member.

5 . The mold opening apparatus of claim 2 , wherein the mold front end engagement mechanism is adapted to horizontally shift towards and away from the front end of the mold carrier member.

6 . The mold opening apparatus of claim 1 , wherein the rotational locking member is adapted to inhibit rotational movement of the rotational movement mechanism during vertical movement of the mold carrier member by the vertical movement mechanism.

7 . The mold opening apparatus of claim 2 , wherein the mold front end engagement mechanism comprises a mold lock engagement mechanism, and wherein the mold lock engagement mechanism is adapted to vertically shift to engage and disengage with a mold lock.

8 . The mold opening apparatus of claim 1 , further comprising a control unit, wherein the control unit is communicatively coupled to the vertical movement mechanism and the rotational movement mechanism and is adapted to control the vertical and rotational movement of the mold carrier member, and wherein the control unit is communicatively coupled to the two or more mold engagement mechanisms.

9 . The mold opening apparatus of claim 1 , wherein the two or more mold engagement mechanisms are coupled to at least one of the front side, the first side, or the second side of the mold carrier member.

10 . A mold opening apparatus, comprising:
a mold carrier member, wherein the mold carrier member comprises: a first side, a second side opposite the first side; a front side, and a back side opposite the front side; a vertical movement mechanism coupled to the mold carrier member; a rotational movement mechanism coupled to the mold carrier member; and two or more mold engagement mechanisms, wherein the two or more mold engagement mechanisms are coupled to at least a portion of the mold carrier member, wherein the two or more mold engagement mechanisms include one or more engagement arms that translate linearly in response to rotation of the mold carrier member and engage and disengage mold parts in a predetermined sequence.

11 . The mold opening apparatus of claim 10 , wherein the two or more mold engagement mechanisms comprise a first mold side engagement mechanism, a second mold side engagement mechanism, and a mold front end engagement mechanism, and wherein the first and second mold side engagement mechanisms are coupled to opposite sides of the mold carrier member and the mold front end engagement mechanism is coupled to a front side of the mold carrier member.

12 . The mold opening apparatus of claim 10 , wherein each of the mold engagement mechanisms includes an engagement arm adapted to translate linearly between an engaged position and disengaged position in response to rotation of the mold carrier member.

13 . A mold opening apparatus, comprising:
a mold carrier member, wherein the mold carrier member comprises: a first side, a second side opposite the first side; a front side, and a back side opposite the front side; a vertical movement mechanism coupled to the mold carrier member; a rotational movement mechanism coupled to the back side of the mold carrier member and adapted to rotate the mold carrier about a fixed axis with a synchronized angular displacement, wherein the rotational movement mechanism comprises a rotational locking member for inhibiting rotational movement during vertical displacement; and one or more mold engagement mechanisms, wherein the one or more mold engagement mechanisms are coupled to at least a portion of the mold carrier member, wherein each mold engagement mechanism includes a shiftable arm having a distal end configured to engage a portion of a mold, and wherein the arm is mechanically linked to rotational displacement of the mold carrier member such that the engagement or disengagement occurs during rotation.

14 . The mold opening apparatus of claim 13 , wherein the rotational movement mechanism includes a gear linkage operatively connected to the one or more mold engagement mechanisms to synchronize rotational displacement with engagement or disengagement of mold parts.

15 . The mold opening apparatus of claim 13 , further comprising a control unit communicatively coupled to the vertical movement mechanism, the rotational movement mechanism, and the one or more mold engagement mechanisms, wherein the control unit is adapted to coordinate vertical and rotational displacement with engagement and disengagement of the mold parts.
