A mold slider release mechanism

Abstract

The invention discloses a mold sliding block unlocking mechanism, which comprises an upper mold core, a lower mold core and a slider demoulding assembly; Components; hanging grooves, screw sinking grooves and inserting rod sinking grooves are set on the movable plate, hanging blocks are set on the upper mold core; countersunk head guide nails are set on the backing plate; the upper end of the inserting rod has a countersunk The countersunk head structure enters the sinking groove of the insertion rod; the elastic movable end of the elastic ejector part cooperates with the movable plate; when the upper mold core is opened, the elastic ejector part can automatically push the movable plate upwards by one end distance, and the movable plate will bring the insertion rod upward The insertion rod is separated from the hole where the workpiece is formed, and the separation of the insertion rod is carried out synchronously with the mold opening action, which improves the mold opening efficiency; and when the upper mold core continues to move upwards, the hanging block will also cooperate with the inclined surface to drive the slider to come off. The mold assembly slides outward, which further improves the mold opening efficiency and ensures the stability of the slide block mold opening.

Description

technical field [0001] The invention relates to a mold sliding block unlocking mechanism, which belongs to the technical field of injection molds. Background technique [0002] Injection mold is a commonly used device in industrial production. Plastic products are processed and produced by injection molding, and some plastic products have a hollow structure on the side. It is necessary to use side sliders in the mold core to assist in molding, and in the parts where the sliders are formed There is also a hole structure. At this time, it is necessary to insert the hole structure forming rod in the slider; but when such a structure is opened, the insertion rod needs to be separated from the injection molded workpiece before the slider can be drawn out, while the existing separation The mechanism needs to be separated step by step, which leads to low mold opening efficiency and cannot meet production needs. Contents of the invention [0003] In view of the above-mentioned ex...
