However, there is a gap between the central clamp and the inner wall of the J-shaped conduit, which cannot achieve a good seal and cushioning. Therefore, there is an urgent need to produce a buffer ring, and a mold for producing the buffer ring is also urgently needed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a buffer ring mold.

[0004] The technical solution of this utility model is as follows:

[0005] A buffer ring mold includes an upper mold and a lower mold.

[0006] The inner ring and outer surface of the upper mold are both semi-circular arcs, the inner wall of the upper mold is provided with an arc-shaped groove, and the lower surface of the upper mold is provided with a ring of grooves.

[0007] Multiple cylinders are fixed on the lower mold. The bottom end of the cylinder is fixed to the lower mold, and the rest passes through the arc groove. A ring of convex strips is provided on the upper surface of the lower mold, and the convex strips are embedded in matching grooves.

[0008] After the upper and lower molds are connected, the area formed by the arc-shaped groove and the surface of the lower mold is the mold cavity.

[0009] Separation grooves are provided at the middle and both ends of the outer walls of the upper and lower molds.

[0010] The lower mold has a hole for the cylinder to pass through. A mounting base is fixed on the bottom surface of the lower mold at the edge of the hole. The mounting base has a threaded hole. One end of the cylinder is fixedly connected to a cylinder base. The cylinder base has a round hole. A fixing bolt passes through the round hole and is screwed into the threaded hole to fix the cylinder.

[0011] Both the upper and lower mold sidewalls are provided with lugs.

[0012] The cylindrical base is located in the groove on the bottom surface of the lower mold.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] It can quickly produce buffer rings, filling the gap in buffer ring production;

[0015] The upper and lower mold structures are reasonably designed, making injection molding convenient, and mold closing and demolding are also relatively easy. Attached Figure Description

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 8 The buffer ring mold shown includes an upper mold 1 and a lower mold 2.

[0026] The inner ring and outer surface of the upper mold 1 are both semi-circular arcs. An arc groove 11 is provided on the inner wall of the upper mold, and a groove 12 is provided on the lower surface of the upper mold.

[0027] The inner ring and outer surface of the lower mold 2 are both semi-circular arcs. Four cylinders 3 are fixed on the lower mold. The bottom end of the cylinder 3 is fixed to the lower mold, and the rest is located in the arc groove and the end passes through the arc groove. A ring of protrusions 21 is provided on the upper surface of the lower mold 2. The protrusions are embedded in the matching grooves. The cylinders 3 are used for the connecting holes of the forming buffer ring. The buffer ring can be fixed to the head of the central clamp by passing bolts through the connecting holes.

[0028] Furthermore, after the upper mold 1 and the lower mold 2 are connected, the area formed by the arc-shaped groove and the surface of the lower mold is the mold cavity. The injection material is injected into the mold cavity, and after cooling, a half buffer ring 6 is formed.

[0029] Furthermore, separation grooves 4 are provided at the middle and both ends of the outer walls of the upper and lower molds to facilitate the separation of the upper and lower molds.

[0030] Furthermore, the lower mold 2 has a hole 22 for the cylinder to pass through, and a mounting base 23 is fixed on the bottom surface of the lower mold at the edge of the hole. The mounting base has a threaded hole 24. One end of the cylinder 3 is fixedly connected to a cylinder base 31. The cylinder base has a round hole. The fixing bolt 32 passes through the round hole and is screwed into the threaded hole to fix the cylinder.

[0031] Furthermore, both the upper and lower mold sidewalls are provided with lugs 5 to facilitate the movement and separation of the upper and lower molds.

[0032] Furthermore, the cylindrical base 31 is located in the groove 25 on the bottom surface of the lower mold.
