[0020] ​​The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0021] As shown in Figure 1 , Figure 2 , Figure 3 A high-efficiency sealing type cement pole mold size head baffle disc, the cement pole mold is composed of an upper mold 1 and a lower mold 2, and feed openings are formed at both ends of the mold.

[0022] The feed openings are closed by the baffle disc 3, and the baffle disc 3 is attached to the end face of the mold to form a detachable sealing connection.

[0023] After the upper mold 1 and the lower mold 2 are combined, a complete pole forming cavity is formed, and the feed openings at both ends are used for injecting cement slurry.

[0024] The baffle disc 3 is installed at the feed opening and is fixed by means of bolts or buckles, so that the baffle disc is tightly attached to the end face of the mold.

[0025] Embodiment 1:

[0026] An annular groove 5 is formed on the outer side of the baffle disc, and a sealing ring 4 is installed in the groove;

[0027] After the sealing ring 4 is installed, its outer side slightly exceeds the outer side of the baffle disc 3, so that when the baffle disc 3 is closed with the mold, the sealing ring 4 can be fully deformed under pressure to form a sealing surface.

[0028] When the mold is closed and the baffle disc 3 is fixed, the sealing ring 4 will be extruded by the end face of the mold due to the excess of the outer side of the baffle disc 3, and will be elastically deformed.

[0029] The deformation of the sealing ring 4 fills the small gap between the baffle disc 3 and the mold, preventing the cement slurry from leaking from the feed opening and ensuring the sealing property of the cavity during pouring.

[0030] Embodiment 2:

[0031] A plurality of arc-shaped elastic blocks 6 are fixed at equal intervals in the annular groove 5, and the arc-shaped elastic blocks 6 are made of rubber or elastic plastic and have a deformation recovery capability;

[0032] A sealing ring 4 is sleeved on the outer side of the arc-shaped elastic blocks, so that the sealing ring 4 is in contact with the arc-shaped elastic blocks 6 and the inner wall of the annular groove 5 at the same time, and the stability of the sealing ring 4 is enhanced by the supporting action of the arc-shaped elastic blocks 6.

[0033] The arc-shaped elastic blocks 6 form an elastic supporting structure in the annular groove 5, and when the sealing ring 4 is extruded, the arc-shaped elastic blocks 6 are deformed synchronously, and the sealing ring is pushed back by the elastic force of the arc-shaped elastic blocks 6, so that the sealing ring is more closely attached to the end face of the mold.

[0034] The buffering effect of the arc-shaped elastic blocks 6 can offset the slight displacement of the mold due to vibration or pressure, avoid the wear or tearing of the sealing ring 4 caused by rigid extrusion, and further improve the sealing reliability.

[0035] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
