DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a bottom mold structure of a spinning mold, comprising

[0021] A bottom mold body 1, an annular bottom groove 11 provided on the bottom surface of the bottom mold body 1, a bottom mold connecting seat 2 connected to the bottom of the bottom mold body 1, and an annular boss 21 welded and fixed to the top surface of the bottom mold connecting seat 2 and inserted into the inner side of the annular bottom groove 11. The bottom mold connecting seat 2 is fixed to the spinning machine by a plurality of fixing bolts in advance to ensure installation stability;

[0022] The plug-in disassembly mechanism 3 includes a plug-in structure, a positioning structure and a blocking structure;

[0023] The plug-in structure includes a T-shaped slot 32 extending through the side of the bottom mold body 1, a socket 33 extending through the surface of the annular boss 21, and a T-shaped plug block 31 inserted into the inner side of the T-shaped slot 32. The end of the T-shaped plug block 31 extends through the socket 33, and the T-shaped plug block 31 itself is limited by a locking structure, which can realize rapid assembly between the bottom mold body 1 and the bottom mold connecting seat 2, and at the same time facilitate subsequent operators to quickly remove the bottom mold body 1 for replacement.

[0024] Among them, the positioning structure includes a slide groove 34 provided inside the bottom mold connecting seat 2, an inner slider 35 and a spring 36 provided inside the slide groove 34, a limiting clamp rod 37 welded and fixed to the top surface of the inner slider 35, and a limiting clamp hole 38 penetrating through the surface of the T-shaped plug block 31. The top end of the limiting clamp rod 37 penetrates into the limiting clamp hole 38, which can stably limit the T-shaped plug block 31 to ensure the connection stability between the bottom mold body 1 and the bottom mold connecting seat 2. The positioning structure also includes a side groove 39 provided on the outer surface of the bottom mold connecting seat 2, a side shift block 310 provided inside the side groove 39, and a side shift block 310 fixed to the side shift block The pull rod 311 on the top surface of 310, the top end of the pull rod 311 passes through the slide groove 34 and is fixed to the bottom surface of the inner sliding block 35, so that the subsequent operator can put his hand into the side groove 39 to pull down the side shift block 310, so that the pull rod 311 moves down with the inner sliding block 35, and the spring 36 is gradually compressed. Finally, as the side shift block 310 is pulled down, the top end of the limit rod 37 moves out of the limit hole 38, and the limit on the T-shaped plug block 31 can be released. At this time, the T-shaped plug block 31 can be pulled out to release the connection between the bottom mold body 1 and the bottom mold connecting seat 2, thereby realizing the rapid replacement of the bottom mold body 1.

[0025] A rod hole is formed between the slide groove 34 and the side groove 39 , and the rod hole corresponds to the pull rod 311 , so as to facilitate the smooth penetration and subsequent sliding of the pull rod 311 .

[0026] Among them, the inner end of the T-shaped slot 32 is communicated with the annular bottom groove 11, so that the T-shaped plug block 31 can be smoothly inserted. The bottom surface of the bottom mold body 1 is provided with a bottom hole corresponding to the position of the limit rod 37, and the bottom hole is communicated with the T-shaped slot 32, so that the top end of the limit rod 37 can pass through smoothly. The top surface of the bottom mold connecting seat 2 is provided with a top hole communicated with the slide groove 34, and the top hole corresponds to the limit rod 37, so that the top end of the limit rod 37 can be smoothly popped out later.

[0027] Example 2

[0028] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that a blocking structure can be provided to prevent foreign objects from entering the side groove 39 during daily use.

[0029] Specifically, the blocking structure includes a rubber sealing plate 312 rotatably mounted on the outer surface of the bottom mold connecting seat 2, and the rubber sealing plate 312 covers the side groove 39, which is used to cover and block the side groove 39 during daily use to prevent the entry of foreign objects from the outside. To pull down the side shift block 310 later, it is only necessary to rotate the rubber sealing plate 312 away from the side groove 39. An integrated rubber protrusion 313 is provided on the inner side of the bottom end of the rubber sealing plate 312. Both are made of rubber material and will undergo elastic deformation when squeezed. The rubber protrusion 313 is squeezed into the side groove 39, which is used to limit the rubber sealing plate 312 to prevent the rubber sealing plate 312 from rotating away from the side groove 39 by itself.

[0030] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
