Quick release die-casting mold ejection mechanism

Abstract

The invention discloses a quick-detachable die-casting mold ejection mechanism, which includes an ejector rod, a concave block, a fixing nut and an ejector plate. The ejector rod includes a first connector and a second connector; the first connector One end of a connector close to the second connector is provided with a first card slot and a first locking threaded hole, and the end of the second connector close to the first connector is provided with a second card slot and a second locking screw hole ; The concave block includes an integrally formed first card platform, a card platform connecting part and a second card platform; the end of the second connector away from the first connector is integrally formed with a screw; the ejector plate passes through The fixing nut is locked on the second connecting head. The invention can effectively solve the problem that the sliding teeth of the screw are locked and difficult to disassemble, and the ejector rod and the ejector plate are easy to replace and disassemble, which can greatly improve the die-casting efficiency, reduce the efficiency of mold replacement, and also reduce the time for abnormal stop operation.

Description

technical field [0001] The invention belongs to the technical field of die-casting molds, and more specifically relates to a die-casting mold ejection mechanism. Background technique [0002] The die-casting mold is a metal mold used to form castings in the die-casting forming process. After the die-casting is formed, it is necessary to use the ejector rod of the ejector mechanism to push the injection-molded product out of the die-casting mold for demoulding. [0003] refer to figure 1 , the ejector mechanism of the existing die-casting mold includes an ejector rod 1a, a lock nut 1b, a screw washer 1c, an ejector plate 1d and a connecting bolt 1e, wherein the ejector rod 1a is provided with a certain length of internal thread, and the connecting bolt 1e extends into the inside of the ejector rod 1a after passing through the screw washer 1c, the ejector plate 1d and the lock nut 1b, thereby locking the ejector plate 1d and the ejector rod 1a together; since the ejector mec...

Problems solved by technology

[0003] refer to figure 1 , the ejector mechanism of the existing die-casting mold includes an ejector rod 1a, a lock nut 1b, a screw washer 1c, an ejector plate 1d and a connecting bolt 1e, wherein the ejector rod 1a is provided with a certain length of internal thread, and the connecting bolt 1e extends into the inside of the ejector rod 1a after passing through the screw washer 1c, the ejector plate 1d and the lock nut 1b, thereby locking the ejector plate 1d and the ejector rod 1a together; since the ejector mechanism of the die-casting mold is working , the ejector plate 1d will drive the ejector rod 1a to move together through the connecting bolt 1e. When the ejector rod 1a is working, the external thread of the connecting bolt 1e and the internal thread of the ejector rod 1a will pull each other, so that the connecting bolt 1e and the ejector rod 1a are subjected to a large pulling force. Under the action of the pulling force, the thread on the connecting bolt 1e and the ejector rod 1a will be deformed and slipped, causing the connecting bolt 1e and the ejector rod 1a to be locked in a large area. If it is fixed together, it is not easy to disassemble and install. If the ejector rod 1a needs to be replaced, the downtime will be longer, which will directly affect the production efficiency of die casting and cause the production capacity to fail to meet the standard.
