Description
Technical Field
The utility model relates to an injection mold's ejection mechanism, especially an injection mold's two-way secondary ejection mechanism.
Background
However, for the automobile interior trim plastic part product like L, under the influence of shape and structural characteristics, single ejection consistent with the mold opening direction cannot achieve the purpose of reliably and completely releasing the core mold of the ornament product, and auxiliary ejection crossed with the mold opening direction must be added to realize the purpose together so as to conform to the application of the injection molding manipulator (arm).
SUMMERY OF THE UTILITY MODEL
The utility model provides an injection mold bidirectional secondary ejection mechanism, sets up in order to solve above-mentioned technical problem, and its technical scheme is:
a main core mold and a side core mold assembly are installed in a core mold plate of the injection mold, and the injection mold bidirectional secondary ejection mechanism comprises a main ejection oil cylinder, a mechanical fastener, an upper top plate, a lower top plate, a bottom plate, a connecting block, a main core mold, a main thimble, a side core mold assembly, a core mold plate and a mandril. A main core mold and a side core mold assembly are assembled in the core mold, a main ejection oil cylinder is installed on the side wall of the core mold, an extension rod of the main ejection oil cylinder is connected with a connecting block, the connecting block is fixed on an upper top plate, a mechanical fastening machine is installed on the upper top plate, two rod pieces in the mechanical fastening machine are respectively fixed with a lower top plate and a bottom plate, the lower top plate is installed below the upper top plate and is in contact with the upper top plate, the bottom plate is arranged below the lower top plate and is in contact with the lower top plate, a main ejector pin and an ejector rod are movably installed in the core mold, the bottom of the main ejector pin is fixed with the lower top plate, and the top of; the side core die assembly comprises a side core die, a side top plate, a side thimble, a side base plate, a side ejection oil cylinder and a side ejection oil cylinder seat, wherein the side base plate is arranged on the left side of the side core die, the side base plate is hollow and is internally provided with the side top plate, the side top plate fixes the bottom of the side thimble, the top of the side thimble is inserted into the side core die, the side ejection oil cylinder seat is installed at the bottom of the side base plate, the side ejection oil cylinder is arranged on the inclined plane of the side ejection oil cylinder seat, and an extension rod of the side ejection oil cylinder penetrates through the side base plate and is connected with the side top plate; the bottom of the ejector rod is fixed with the upper top plate, and the top of the ejector rod is connected with the bottom of the side backing plate.
The method and principle of use are as follows:
after the mold is opened, under the action of the pulling force of the main ejection oil cylinder and the mechanical fastener, the upper ejector plate drives the ejector rod and the lower ejector plate to drive the main ejector pin to move upwards, the side core mold and the part of the ornament product formed in the main core mold are ejected synchronously, and when the mechanical fastener is released, the ejection is finished once, and the lower ejector plate stops moving upwards; and the upper top plate continues ejecting the side core mold, when the retraction distance of the main ejection oil cylinder reaches a set position, secondary ejection is completed, the upper top plate stops moving upwards, and the back-off on the ejected part of the ornament product is completely separated from the main core mold. Then, the side top plate drives the side ejector pin to eject out the part of the ornament product formed in the side core mold under the pushing of the side ejector oil cylinder until the lateral reverse buckle on the ornament product is completely separated from the side core mold. So far, the ornament product is subjected to integral demolding.
Before the die is closed, the side ejection oil cylinder is pulled back, the side ejector pins return to the side core die, then the main ejection oil cylinder pushes the upper top plate to drive the side core die to return, and after the mechanical fastener is closed, the upper top plate and the lower top plate drive the side core die and the main ejector pins to return synchronously until the extension distance of the main ejection oil cylinder reaches a set position.
Has the advantages that:
the bidirectional secondary ejection mechanism is additionally provided with independent lateral ejection on the basis of secondary ejection along the die opening direction, the ejection and return are stable, ordered and effective under the control of the bidirectional independent oil cylinder, the requirement of the injection molding automation of automobile ornaments similar to the shape of L is met, and the shape, structural integrity and high appearance quality stability of the ornament products are ensured.
