Abstract
The utility model provides a mandril quick-change structure, which comprises a mandril special for quick change, wherein a quick-change plug is sleeved at the lower end of the mandril special for quick change, a mould is connected at the upper end of the mandril special for quick change in a penetrating way, and a mandril fixing plate is connected at the lower end of the mandril special for quick change in a penetrating way; the utility model discloses use this mesostructure after, only need demolish solitary ejector pin quick change end cap and can realize the change of single ejector pin, in later stage maintenance mould, saved a large amount of manual works and time.
Description
Technical Field
The utility model relates to a ejector pin structure field of mould especially relates to ejector pin quick change structure.
Background
In the plastic mold and the die-casting mold, the ejector rod is mainly used for separating an injection-molded product from a male mold or a female mold. When in injection molding or die casting, some parts are wrapped on the male die or are left in the female die, and then the ejector rod is required to eject the parts out to separate the parts from the male die or the female die. In the cold die, a ram or ejector plate is used to eject the punched or bent piston or drawing piston out of the die.
However, in the arrangement process of the ejector rods of the large-scale low-pressure die, the ejector rods are arranged in a plurality and need to be replaced, and under the condition, the ejector rods are difficult to take out, so that a large amount of labor and time are wasted.
SUMMERY OF THE UTILITY MODEL
To the above defect of prior art, the utility model provides a ejector pin quick change structure, including special ejector pin 1 of quick change, the pot head is equipped with quick change end cap 2 under the special ejector pin 1 of quick change, 1 upper ends of the special ejector pin of quick change are worn to establish and are connected with mould 3, 1 lower extreme of the special ejector pin of quick change is worn to establish and is connected with ejector pin fixed plate 4.
Preferably, the upper end of the ejector rod 1 special for quick change penetrates through the mold 3 to the surface of the mold cavity 5 of the mold 3.
Preferably, the ejector rod 1 special for quick change and the die 3 are arranged perpendicular to each other.
Preferably, the special ejector rod 1 for quick change and the ejector rod fixing plate 4 are arranged perpendicular to each other.
Preferably, the quick-change plug 2 is located inside the ejector rod fixing plate 4 and is attached to the lower surface of the ejector rod fixing plate 4.
The utility model has the advantages that: after the structure is used, the replacement of a single ejector rod can be realized only by detaching the quick-change plug of the independent ejector rod, and a large amount of labor and time are saved in the later maintenance of the die.

Detailed Description
In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.
As shown in fig. 1-3, the present invention comprises: the special ejector rod 1 of quick change, the pot head that overlaps under the special ejector rod 1 of quick change is equipped with quick change end cap 2, the special ejector rod 1 upper end of quick change is worn to establish and is connected with mould 3, the special ejector rod 1 lower extreme of quick change is worn to establish and is connected with ejector rod fixed plate 4.
In use, the ejector rods of the large-scale low-pressure die are arranged, the ejector rods are positioned and fixed, and meanwhile, the easy-to-disassemble design provides convenience for the replacement of the follow-up ejector rods.
In the present embodiment, it is preferable that the upper end of the ejector rod 1 dedicated for quick change penetrates the mold 3 to the surface of the cavity 5 of the mold 3.
In the present embodiment, the ejector rods 1 dedicated for quick change and the mold 3 are preferably arranged perpendicular to each other.
In this embodiment, the ejector rod 1 dedicated for quick change and the ejector rod fixing plate 4 are preferably arranged perpendicular to each other.
After the structure is used, the replacement of a single ejector rod can be realized only by detaching the quick-change plug of the independent ejector rod, and a large amount of labor and time are saved in the later maintenance of the die.
The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
