Simple and easy twice distance-determination push-out device

Abstract

The invention discloses a simple and easy twice distance-determination push-out device, which comprises a cold charge head pushing plate (1), a pushing column (11), a product pushing plate (2) and a distance determination hook (3). The simple and easy twice distance-determination push-out device is composed of the cold charge head pushing plate, the pushing column, the product pushing plate and the distance determination hook. The cold charge head pushing plate is disposed above the product pushing plate, and the center of the bottom of the cold charge head pushing plate is provided with the pushing column. The pushing column slides to penetrate through the product pushing plate, the distance determination hook is fixedly arranged on the edge of the cold charge head pushing plate, a distance determination gap is reserved between the distance determination hook and the product pushing plate for hook connection. During a demoulding process, a tail pushing column of an injection moulding machine pushes the pushing column, the cold charge head pushing plate and a cold charge head pushing rod to enable a cold charge head to be separated from a product first. When the cold charge head pushing plate travels to the completion distance determination gap, the technical scheme that the product pushing plate and a product pushing rod of the distance determination hook push the product to be separated overcomes defects in the prior art that structure is complicated, manufacture period is long and cost is high, and achieves the purposes of simplifying structure, shortening work period and lowering cost.

Description

technical field [0001] The invention relates to an ejection device of an injection mold, in particular to a simple secondary fixed-distance ejection device used for ejecting an injection mold with a set stroke distance in two stages. Background technique [0002] The secondary fixed-distance ejection of the injection mold means that the injection mold can automatically separate the main gate, runner, and cold head of the sub-gate from the injection molded product during ejection and demoulding to realize automatic production. That is, it is necessary to separate the product from the cold material head first, and then push the product and the movable mold core to be demolded. There are many types of secondary fixed-distance ejection mechanisms for injection molds in the prior art, such as a three-plate mold with a stripper plate. The structure is complex, the manufacturing period is long, and the cost is high; therefore, the prior art has the problems and shortcomings of a co...
