Detailed Description

The present utility model will now be described in further detail with reference to the drawings and examples, wherein it is apparent that the examples described are only some, but not all, of the examples of the utility model. Embodiments and features of embodiments in this application may be combined with each other without conflict. All other embodiments, based on the embodiments of the utility model, which would be apparent to one of ordinary skill in the art without inventive effort are within the scope of the utility model.

It should be noted that, in the embodiment of the present utility model, directional indications (such as up, down, left, right, front, and rear … …) are referred to, and the directional indications are merely used to explain the relative positional relationship, movement conditions, and the like between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.

In addition, "a plurality of" means two or more. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed by the utility model.

Examples: the novel aluminum pipe demoulding device comprises a punch body 1, a valve core 2, a first vent hole 3, a second vent hole 4 and a compressed air hole 5, wherein a hole 6 is formed in one end of the punch body 1, the punch body 1 is located in the hole 6, the valve core 2 is movably filled in the hole 6, a plurality of first vent holes 3 are uniformly formed in one side of the periphery of the valve core 2 on the punch body 1, a plurality of second vent holes 4 are uniformly formed in one side of the inside of the valve core 2 on the punch body 1, the first vent holes 3 are located on one side of the outside of the second vent holes 4, compressed air is required to be introduced into the center of one end of the valve core 2 in the punch body 1 when the aluminum pipe is removed for demoulding, a cavity caused by rapid demoulding is supplemented, flat pipes and oval pipes are avoided, the common vent holes are cut into rectangular air grooves on the cylindrical surface of the valve core, and the valve core is blocked and the valve core is usually pushed out slowly.
