Embodiment 2

[0045] In this embodiment, the ejector mechanism is a limit rod mechanism, which is arranged in the inner cavity of the mold, and includes a limit rod 7 and a limit cavity 8. One end of the limit rod 7 is threaded as a threaded connection part 71, and the other end has a convex The edge-shaped limit blank head 72 and the threaded connection part 71 are screwed and fixedly connected with the ejector plate 5 . When the injection mold of the present invention is a multi-layer injection mold, a limit rod mechanism is also respectively set between the movable template assembly and the intermediate plate assembly, and between the intermediate plate assembly and the fixed template assembly. If the mold opening stroke is small, the two directions The limit pull rod mechanisms on the top can be set relatively. If the mold opening stroke is large, in order to avoid increasing the thickness of the mold, the limit pull rod mechanisms in the two directions should be staggered. Wherein, the...

Abstract

The invention provides an injection mould with ejection and linkage mechanisms, thus providing a solution to problems of complex oil cylinder structure, high cost and low productivity which exist in present injection moulds employing an oil cylinder ejection mechanism. In the invention, two ejection mechanisms are installed. One end of the ejection mechanisms are connected to liftout plates on the side of the mould core, with the other end connected to one mould side where a cavity is located. The ejection mechanisms are directly driven by mould opening actions of the mould to power the liftout plates so as to eject products. Employing a mechanical structure, the ejection mechanisms of the injection mould are characterized by simple structure, low cost and short injection moulding cycle, and play a key role in achieving fast and efficient manufacturing for the injection mould.

Description

technical field [0001] The invention relates to the field of mold design, in particular to an injection mold with an ejection linkage mechanism. Background technique [0002] Usually, when molded products, the cavity of the single-layer mold is in the fixed mold part, the core is in the movable mold part, and the movable mold part needs to have an ejection action to achieve the purpose of ejecting multiple products. The mold of the multi-layer mold Both fixed and movable molds need to have ejection action to achieve the purpose of ejecting multiple products at the same time. At present, an oil cylinder mechanism is generally used to drive the ejector plate to complete the ejection of the product. The oil cylinder mechanism of the single-layer mold is fixed on the movable platen, and the oil cylinder mechanism of the multi-layer mold is fixed on the fixed and movable platen. The head of the oil cylinder is connected to the ejector plate. , all oil cylinders are connected to ...
