In order to make the objects, features and advantages of the present invention more apparent and understandable, the embodiments of the present invention will be described in detail and completely with reference to the accompanying drawings, and it is to be understood that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. It should be noted that when one component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present.

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

The embodiment of the utility model provides a pressure maintaining die which can effectively reduce the difficulty of detaching an upper die 1 from a positioning column 21 when the positioning column 21 is worn and bent.

Referring to fig. 1 to 5, the pressure maintaining jig includes an upper mold 1 and a lower mold 2, wherein the lower mold 2 is fixedly connected with a positioning column 21, and in an actual working process, the upper mold 1 can slide along the positioning column 21 to achieve mold closing and pressure maintaining or mold opening and workpiece taking;

in the present embodiment, the upper die 1 includes a main body 11, a position adjusting assembly 3 mounted on the main body 11, and a cover plate 12 mounted on the position adjusting assembly 3;

the position adjusting assembly 3 is used for adjusting the distance between the cover plate 12 and the main body 11, so that the main body 11 and the cover plate 12 form a positioning hole matched with the positioning column 21. It should be noted that, when the upper die 1 needs to be detached from the positioning post 21, the position adjusting assembly 3 is used to adjust the distance from the cover plate 12 to the main body 11, so that the cover plate 12 can be separated from the positioning post 21, which is equivalent to increasing the cross-sectional dimension of the positioning hole; the increase of the section size of the positioning hole is equivalent to the release of the positioning column 21 from the positioning hole, and the positioning column 21 is not clamped in the positioning hole any more, so that the difficulty of detaching the upper die 1 from the positioning column 21 is reduced.

Optionally, the position adjusting assembly 3 includes a plurality of positioning studs 31 mounted on the main body 11 and an adjusting nut 32 for adjusting the position of the cover plate 12, the plurality of positioning studs 31 are parallel to each other; the cover plate 12 is provided with mounting through holes corresponding to the positioning studs 31 one by one, the positioning studs 31 pass through the mounting through holes, and the adjusting nut 32 is mounted at one end of the positioning studs 31 passing through the mounting through holes. Wherein, the adjusting nut 32 is screwed with the positioning stud 31, and the adjusting nut 32 can push the cover plate 12 to move along the positioning stud 31, thereby adjusting the distance between the cover plate 12 and the main body 11. It should be noted that when the adjusting nut 32 is located at the set position, a positioning hole is formed between the adjusting cover 12 and the main body 11, and at this time, the adjusting cover 12 is slidably attached to the positioning post 21.

Optionally, the position adjustment assembly 3 further comprises an elastic member 33 compressively mounted between the cover plate 12 and the main body 11, one end of the elastic member 33 abuts against the cover plate 12, and the other end abuts against the main body 11. When the adjusting nut 32 moves in a direction away from the main body 11, the elastic force of the elastic member 33 pushes the cover plate 12 away from the main body 11, so that the positioning post 21 is disengaged from the positioning hole.

It should be noted that, due to the arrangement of the elastic member 33, when the upper die 1 is separated from the positioning column 21, the shape of the positioning hole can still be kept unchanged, so that an operator can conveniently reinstall the upper die on the positioning column 21, and the installation difficulty of the operator is reduced.

Optionally, a first groove 111 is provided on the side of the main body 11 close to the cover plate 12; a second groove 121 opposite to the first groove 111 is arranged on the side surface of the cover plate 12 close to the main body 11, and the first groove 111 and the second groove 121 can enclose to form a positioning hole;

the shapes of the first groove 111 and the second groove 121 are matched with the shape of the positioning column 21, so that the inner walls of the first groove 111 and the second groove 121 can be slidably attached to the surface of the positioning column 21.

In a specific embodiment, as shown in fig. 7, the cross section of the positioning column 21 is a perfect circle, the cross sections of the first groove 111 and the second groove 121 are both arc-shaped, and both the first groove 111 and the second groove 121 can be slidably fitted on the surface of the positioning column 21.

In another specific embodiment, as shown in fig. 8, the cross section of the positioning column 21 is rectangular, the first groove 111 and the second groove 121 are both V-shaped grooves, and the walls of the V-shaped grooves are both in sliding fit with the surface of the positioning column 21.

Optionally, as shown in fig. 6, a guide post 4 parallel to the positioning stud 31 is further mounted on the main body 11, the cover plate 12 is provided with a sliding through hole matching with the guide post 4, and the cover plate 12 is slidably mounted on the guide post 4; specifically, the cover plate 12 can only slide along the guide post 4, which avoids the situation that one end of the positioning hole has a larger size and the other end has a smaller size under the action of the elastic force of the elastic members 33, and is more convenient for an operator to install or dismantle the cover plate 12.

Optionally, the adjustment nut 32 is a wing nut that can be manually turned by an operator without the need for a workpiece. Therefore, tools are not needed for disassembling the upper die or assembling the upper die, and the position of the cover plate 12 can be conveniently adjusted by an operator.

Optionally, the elastic member 33 is a spring, and the spring is sleeved on the positioning stud 31. It should be noted that the spring may be mounted in other ways as long as one end of the spring abuts against the main body 11 and the other end abuts against the cover 12. The spring is sleeved on the positioning stud 31, so that the situation that the spring falls off can be effectively avoided.

The above-mentioned embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the same; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
