[ detailed description ] embodiments
Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar functions throughout.
In the present invention, unless otherwise expressly specified or limited, the terms "assembled", "connected", and "connected", if any, are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integrally connected; or may be a mechanical connection; the two elements can be directly connected or connected through an intermediate medium, and the two elements can be communicated with each other. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.
The technical solution and the advantages of the present invention will be more clear and clear by further describing the embodiments of the present invention with reference to the drawings of the specification. The embodiments described below are exemplary and are intended to be illustrative of the present invention, but should not be construed as limiting the invention.
The utility model provides a preferred embodiment: as shown in fig. 1 to 4, a straight ejector rod and gasket structure comprises a straight ejector rod 10, a gasket 20 and a template 30, wherein the diameter of the gasket 20 corresponds to that of the straight ejector rod 10.
The straight ejector rod 10 is provided with a threaded hole 11, and the threaded hole 11 is connected with a mating screw 40; the mating screw 40 comprises an insertion rod 41 and a clamping head 42, and the diameter of the insertion rod 41 is matched with that of the threaded hole 11; the gasket 20 is assembled at the bottom of the straight ejector rod 10, and the gasket 20 is arranged between the bottom of the straight ejector rod and the clamping head;
the spacer 20 has a serial hole 21 and a escape hole 22, and the insertion rod 41 is inserted into the screw hole 11 through the serial hole 21; the diameter of the avoiding hole 22 is larger than that of the serial hole 21, the avoiding hole 22 is arranged in the middle of the gasket 20, the avoiding hole is respectively spaced from the top end face and the bottom end face of the gasket, and the weight of the gasket can be reduced by arranging the avoiding hole. The number of the gaskets is one or more, and the assembling height of the straight ejector rod is adjusted by adjusting the number of the gaskets.
The template 30 comprises a middle die 31 and a bottom die 32; the middle die 31 is provided with a connecting cavity 33, and the straight ejector rod 10 is connected into the connecting cavity 33; the upper part of the bottom die 32 is provided with a bearing cavity 34 for placing the gasket 20, and the height of the bearing cavity 34 is greater than the thickness of the gasket 20 so as to accommodate more gaskets; the bottom end of the bottom die 32 is provided with a containing cavity 35 for accommodating a chuck 42 of a mating screw, and a serial cavity 36 for accommodating a plug rod 41 of the mating screw is arranged between the containing cavity 34 and the containing cavity 35.
