Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly stated or limited, the terms "mounted," "connected" and "connected" are to be understood broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected, mechanically connected, electrically connected, directly connected, indirectly connected through an intermediate medium, or connected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The crosshead pressing plate easy to detach shown in fig. 3-5 comprises a left half body 501 and a right half body 502, the left half body 501 and the right half body 502 are connected in an abutting mode and are circular, a plurality of countersunk holes 503 are formed in the left half body 501 and the right half body 502 respectively, a wrench extends into a window 201 formed in the middle body 200, and can screw down or screw down screws penetrating the countersunk holes 503 in the left half body 501 or the right half body 502. The line of the contour of the contact surface of the left half 501 and the right half 502 is projected on a plane perpendicular to the contact surface in a straight line.

When the old plunger 600 needs to be removed from the front end of the guide cylinder 400 without removing the middle body 200, a wrench can be inserted into the window 201 formed in the middle body 200, the screws on the countersunk holes 503 of the left half body 501 and the right half body 502 are respectively screwed down, the left half body 501 and the right half body 502 can be taken out from the window 201, and the old plunger 600 is naturally separated from the front end of the guide cylinder 400 and is pulled out from the front end of the lower die head 100. When a new plunger 600 needs to be replaced, the operation is reversed, and the operation is very convenient.

Embodiment 2 is the same as embodiment 1 except that projections of the contour lines of the abutment surfaces of the left half-body 501 and the right half-body 502 on a plane perpendicular to the abutment surfaces are V-shaped as shown in fig. 6 to 7. Therefore, the left half body 501 and the right half body 502 can be mutually nested, the flatness of the abutting surface of the column head of the plunger 600 is enhanced, and the stability and the sealing performance are improved.

Example 3 is the same as example 1 except that projections of the contour lines of the abutment surfaces of the left half-body 501 and the right half-body 502 on a plane perpendicular to the abutment surfaces are zigzag as shown in fig. 8 to 9. Therefore, the left half body 501 and the right half body 502 can be nested with each other, the flatness of the contact surface of the plunger 600 column cap is enhanced, and the stability and the sealing performance are improved.

Example 4 is the same as example 1 except that the contour lines of the abutment surfaces of the left half-body 501 and the right half-body 502 are projected in a bow shape on a plane perpendicular to the abutment surfaces, as shown in fig. 10 to 11. Therefore, the left half body 501 and the right half body 502 can be subjected to mortise-tenon insertion, the flatness of the column cap abutting surface of the plunger 600 is enhanced, and the stability and the sealing performance are improved.

The invention has not been described in detail in order to avoid obscuring the invention in view of the prior art or the common general knowledge in the field.
