Description

Technical Field

[0001] The utility model relates to the technical field of die-related equipment, and more specifically, to a die pre-ejecting mechanism. Background Art

[0002] A die is various molds and tools used in industrial production to obtain required products by methods such as injection molding, blow molding, extrusion, die casting, or forging, smelting, stamping, etc. In short, a die is a tool for making formed articles, and this tool is composed of various parts, and different dies are composed of different parts.

[0003] This structure can realize the pre-ejection of the ejector plate during the mold opening process, and can also realize that the ejector plate does not reset after ejection, but resets during the mold closing process. In this way, some mold actions with special requirements can be realized. Previously, to achieve similar actions, either a flexible mechanism such as a spring was used, the disadvantage of which is that it will become fatigued and unreliable after a long time of use; or a mechanism such as a cylinder was used, the disadvantages of which are that it occupies a large space, has a small force, and the action is unreliable. For this reason, we propose a die pre-ejecting mechanism. Summary of the Utility Model

[0004] Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a die pre-ejecting mechanism. When the mold opening action is performed in the utility model, the reset rod is installed on the fixed mold and moves along with the fixed mold; when the ejector plate is ejected, when the dial block presses against the side surface of the slider, the slider can only move horizontally under the pressure of the guide rail, driving the stop block to move. The stop block pops out under the action of the spring and falls into the square hole of the wear-resistant plate to lock the mechanism from the inside. The top block is installed in the vertical groove of the guide rail and can only move up and down. The horizontal movement of the slider pushes the top block to move downward. When the mold closing action is performed, the reset rod moves together with the fixed mold to close the mold. When it presses the stop block into the slider, the mechanism is unlocked, and then the mold continues to close. The top block moves upward to push the slider to move and reset, and the mold closing is completed.
