Description

Technical Field

[0001] This utility model relates to the field of air spring mold technology, specifically a combined air spring mold. Background Technology

[0002] Air springs, as elastic elements that use compressed air as the elastic medium, are widely used in automotive suspensions, rail transportation, and construction machinery due to their adjustable load-bearing capacity and excellent shock absorption performance. Their core component is a rubber air bladder, which is typically formed through vulcanization molding.

[0003] Most air spring molds currently use an integrated structure. While this design can ensure structural stability during the molding process and has a lower overall processing difficulty, the cavity and frame of the integrated mold are fixedly connected. After the air spring is vulcanized, there is a strong adsorption force between the rubber product and the inner wall of the mold cavity. However, in actual production, there are obvious inconveniences in the demolding process. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides a combined air spring mold, comprising: a base plate 1 and a disc 2 mounted on the top of the base plate 1, and further comprising: multiple equally spaced strip-shaped openings 3 on the top outer wall of the disc 2, multiple equally spaced adjusting components 4 rotatably mounted on the inner wall of the strip-shaped openings 3, and outer templates 5 and inner templates 6 respectively mounted at the bottom ends of the adjusting components 4, multiple equally spaced inner mold parts 7 mounted on the top outer wall of the base plate 1, a motor 8 mounted above the disc 2, a drive bevel gear 9 mounted at the bottom of the output shaft of the motor 8, and a sealing component 10 mounted in the middle of the top outer wall of the base plate 1.

[0021] It should be noted that: the motor 8 drives the active bevel gear 9 to rotate, and through gear meshing, it drives the adjustment component 4 to move, causing the outer template 5 and the inner template 6 to move; the inner mold part 7 cooperates with the outer template 5 and the inner template 6 to form an air spring forming cavity, and the sealing component 10 ensures that the cavity is sealed during the vulcanization process, realizing a combined mold; after molding, the template is separated by the reverse action of the adjustment component 4, so that the various components of the mold are separated, realizing convenient demolding.

[0022] In a preferred embodiment, the adjusting assembly 4 includes a bidirectional threaded rod 401, a moving block 402 screwed to both ends of the bidirectional threaded rod 401, and a driven bevel gear 403 mounted on one end of the bidirectional threaded rod 401.

[0023] It should be noted here that the driven bevel gear 403 receives power from the driving bevel gear 9 and drives the bidirectional threaded rod 401 to rotate. The moving block 402 is screwed to the bidirectional threaded rod 401, converting the rotational motion of the threaded rod into its own linear motion, thereby driving the outer template 5 and the inner template 6 to move.

[0024] In a preferred embodiment, the threads at both ends of the bidirectional threaded rod 401 are in opposite directions, and the outer template 5 and the inner template 6 are respectively fixed to the bottom of the two moving blocks 402.

[0025] In a preferred embodiment, a plurality of driven bevel gears 403 are arranged in a ring around the driving bevel gear 9, and the driven bevel gears 403 mesh with the driving bevel gear 9.

[0026] It should be noted here that: because the threads at both ends of the bidirectional threaded rod 401 are reversed, when it rotates, it will drive the two moving blocks 402 to move towards each other or away from each other, thereby causing the outer template 5 and the inner template 6 to move closer or separate synchronously.

[0027] In a preferred embodiment, the sealing assembly 10 includes an electric push rod 1001 and an annular plate 1002 mounted on top of the electric push rod 1001.

[0028] It should be noted that during vulcanization molding, the electric push rod 1001 drives the annular plate 1002 to descend, which fits tightly with the outer mold 5, the inner mold 6 and the inner mold 7 to form a sealed cavity, preventing the rubber material from overflowing and maintaining the pressure required for vulcanization. After molding is completed, the electric push rod 1001 pushes the annular plate 1002 to rise, releasing the seal and facilitating subsequent demolding operations.

[0029] In a preferred embodiment, the inner template 6 and the inner template 7 are staggered.

[0030] It should be noted that: the inner templates 6 are separated by an inner mold piece 7, and the inner templates 6 will not obstruct each other during the process of moving inward through the adjusting component 4.

[0031] Working principle: Motor 8 drives the active bevel gear 9 to rotate. The driven bevel gear 403 receives the power from the active bevel gear 9 and drives the bidirectional threaded rod 401 to rotate. The moving block 402 is screwed to the bidirectional threaded rod 401, converting the rotational motion of the threaded rod into its own linear motion, which in turn drives the outer template 5 and the inner template 6 to move closer to each other. The inner mold part 7 cooperates with the outer template 5 and the inner template 6 to form an air spring forming cavity. The electric push rod 1001 drives the annular plate 1002 to descend, which fits tightly with the outer template 5, the inner template 6 and the inner mold part 7 to form a sealed cavity, preventing the rubber raw material from overflowing and maintaining the pressure required for vulcanization, thus realizing a combined mold.

[0032] After molding is completed, the electric push rod 1001 pushes the annular plate 1002 to rise, releasing the sealing state. The motor 8 drives the active bevel gear 9 to rotate in the opposite direction, so that the outer template 5 and the inner template 6 move away from each other, achieving convenient demolding.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
