Ejection mechanism of precision die

Technical Field

The utility model relates to the technical field of precision dies, in particular to an ejection mechanism of a precision die.

Background

The precision injection mold is a device for obtaining a product having a certain shape after injecting a resin material into a metal mold. In fact, in order to control the temperature of the mold, the mold is provided with cooling holes, heaters, and the like for passing the refrigerant. The material which becomes melt enters the main runner, and is injected into the die cavity through the sprue. After the cooling stage, the mould is opened, the ejector rod in the injection molding and die casting mould is mainly used for separating the injection molded product from the male mould or the female mould, and when in injection molding or die casting, some living bodies are wrapped on the male mould or left in the female mould, and at the moment, the ejector rod is required to be ejected out to separate the living bodies from the male mould or the female mould;

the existing ejection mechanism of the die generally adopts a single ejector rod for ejection, and the single ejector rod is small in ejection pressure area, so that the existing ejection mechanism of the die is easy to damage when the die with high precision is ejected, the product quality of the die is reduced, the production cost is increased, the product quality is reduced, and the actual use is not facilitated.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, the present utility model provides a technical solution: including equipartition ejection mechanism, equipartition ejection mechanism is including shaping die cavity 1, hold frame 11, always move disc 12, ejector rod 13 and booster spring 14, wherein hold the frame 11 and fix in one side of shaping die cavity 1, always move disc 12 setting in the inside of holding frame 11, wherein ejector rod 13 evenly runs through the setting on shaping die cavity 1, booster spring 14 overlaps on ejector rod 13. The booster springs 14 are located inside the accommodating frame 11, and the number of the booster springs 14 may be smaller than the number of the ejector rods 13, and the ejector rods 13 are in a T-shaped arrangement.

The ejector rods 13 are arranged through the molding cavity 1, wherein the number of groups of the ejector rods 13 is nine. The ejector rods 13 bear the ejection of the die inside the molding die cavity 1 together, so that the die cannot be damaged, the ejector rods 13 move to eject the total moving disc 12 by means of gradual pressurization of air pressure, and therefore the die can be ejected and unloaded, and the die cannot be impacted suddenly and damaged, so that the quality of the die is effectively guaranteed.
