Abstract
An ejector assembly for removing a molded part from a mold includes an ejector arm and mounting structure. The ejector arm has a first end with a tongue that extends partially into a cavity of the mold and an opposite second end with a handle that extends outwardly from the mold cavity. The mounting structure pivotally mounts the ejector arm to the top portion of the mold so that the ejector arm may be pivoted between an operating position and an ejection position.
Claims18
An ejector assembly for removing a molded part from a mold, the ejector assembly comprising:
- an ejector arm having a first end and an opposite second end;
- and
- a mounting structure for pivotally mounting the ejector arm to the mold, wherein the mounting structure allows the ejector arm to be pivoted between an operating position in which the first end of the ejector arm extends into a mold cavity of the mold during formation of a part in the mold and an ejection position in which the first end of the ejector arm is shifted out of the cavity to urge the part from the cavity, wherein the first end of the ejector arm includes a tongue that extends at least partially into the mold cavity when the ejector arm is in the operating position and the second end of the ejector arm includes an elongated handle that extends outwardly from the mold, wherein the tongue moves from the operating position to the ejection position when the handle is lifted.
An ejector assembly for removing a molded part from a mold, the ejector assembly comprising:
- an ejector arm having a first end and an opposite second end;
- a mounting structure for pivotally mounting the ejector arm to the mold, wherein the mounting structure allows the ejector arm to be pivoted between an operating position in which the first end of the ejector arm extends into a mold cavity of the mold during formation of a part in the mold and an ejection position in which the first end of the ejector arm is shifted out of the cavity to urge the part from the cavity;
- and
- a locking pin that extends through aligned holes in the ejector arm and the mounting structure for preventing pivotal movement of the ejector arm, wherein the locking pin may be removed from the aligned holes to permit the pivotal movement of the ejector arm.

An ejector assembly for removing a molded part from a mold, the ejector assembly comprising:
- an ejector arm having a first end and an opposite second end;
- a mounting structure for pivotally mounting the ejector arm to the mold, wherein the mounting structure allows the ejector arm to be pivoted between an operating position in which the first end of the ejector arm extends into a mold cavity of the mold during formation of a part in the mold and an ejection position in which the first end of the ejector arm is shifted out of the cavity to urge the part from the cavity and wherein the mounting structure includes a mounting bracket, the mounting bracket comprising:
- a pair of spaced apart mounting arms for securement to the top mold portion;
- and
- a pair of spaced apart legs to which the handle of the ejector arm may be pivotally secured.

An ejector assembly for removing a molded part from a mold, the ejector assembly comprising:
- an ejector arm having a first end and an opposite second end;
- and mounting structure for pivotally mounting the ejector arm to the mold, wherein the mounting structure allows the ejector arm to be pivoted between an operating position in which the first end of the ejector arm extends into a mold cavity of the mold during formation of a part in the mold and an ejection position in which the first end of the ejector arm is shifted out of the cavity to urge the part from the cavity and wherein the mold is a pallet mold and the part formed in the mold is a pallet.
An ejector assembly for removing a molded pallet from a mold, the mold having a top mold portion and a bottom mold portion that define a mold cavity, the ejector assembly comprising:
- an ejector arm having a first end with a tongue and an opposite second end with a handle;
- and
- a mounting bracket for pivotally mounting the ejector arm to the top portion of the mold so that the first end of the ejector arm and the tongue extend partially into the cavity of the mold and the opposite second end of the ejector arm and handle extend outwardly from the mold, wherein the mounting bracket allows the ejector arm to be pivoted between an operating position in which the first end and the tongue extend into the mold cavity during formation of a pallet in the mold and an ejection position in which the first end and the tongue are shifted from the cavity to urge the pallet from the cavity after the pallet is formed.
A mold for forming a pallet, the mold comprising:
- a top mold portion having a semi-cylindrical opening in one of its sides;
- a bottom mold portion having a semi-cylindrical opening in one of its sides that is aligned with the semi-cylindrical opening in the top mold to form a circular opening in the mold when the top mold portion is attached to the bottom mold portion;
- an ejector assembly for removing a molded part from the mold, the ejector assembly comprising:
- an ejector arm having a first end with a tongue and an opposite second end with a handle;
- and
- mounting structure for pivotally mounting the ejector arm to the top portion of the mold so that the ejector arm extends though the circular opening in the mold, the mounting structure permitting the ejector arm to be pivoted between an operating position in which the tongue extends into the mold cavity during formation of the pallet and an ejection position in which the tongue is shifted downwardly and out of the mold cavity to urge the pallet from the top portion of the mold.
