Problems solved by technology

[0003] The existing flexible mold has the following defects in use: first, the lower steel ring is directly fixed to the lower chuck, and when vulcanizing tires of the same size and different specifications, the lower steel ring needs to be removed from the lower chuck, and then the lower steel ring of the corresponding specification is selected. The ring and the lower chuck are fixed for use, and the lower side plate must be replaced accordingly. The operation is cumbersome, time-consuming and laborious, and the utilization rate of the workpiece is reduced; secondly, during t...

Method used

As shown in Figure 2, a kind of active mold for tire building vulcanizing machine comprises lower chuck 2 and upper chuck 3 that are connected with vulcanizing machine central mechanism 1 respectively, and lower chuck 2 and upper chuck 3 pass through respectively The bolts are fixedly connected with the transition plate 4 and the upper steel ring 5, the lower chuck 2 and the transition plate 4 clamp the bottom edge of the capsule 6, and the upper chuck 3 and the upper steel ring 5 clamp the top edge of the capsule 6. The outer side of the disc 4 is provided with a lower steel ring 7, the bottom edge of the transition disc 4 is matched with the lower steel ring 7, and the lower steel ring 7 is fixedly installed on the lower side plate 8, and the lower side plate 8 is then installed on the base table panel 9. After the tire is vulcanized, the water cylinder of the central mechanism 1 of the vulcanizing machine is extended, the superheated water in the bladder 6 is discharged, the bladder 6 is stretched, and then the lower chuck 2 and the transition plate 4 are lifted up to release the tire from the mold. , and then the tire unloading trolley drags the tire, the water cylinder 1 of the central mechanism of the vulcanizing machine descends and resets, and the trolley turns the tire onto the conveyor belt.

Abstract

The invention provides an adjustable mold for a tyre molding vulcanizing machine. The adjustable mold comprises a lower chuck and an upper chuck, which are connected with a vulcanizing machine central mechanism; the lower chuck and the upper chuck are fixedly connected with a transition disc and an upper steel ring by bolts respectively; the lower chuck and the transition disc are used for clamping a clamping edge part of the bottom of a capsule; the clamping edge part at the top of the capsule is clamped by the upper chuck and the upper steel ring; a lower steel ring is arranged on the outer side of the transition disc; the edge of the bottom of the transition disc is matched with and in butt joint with the lower steel ring; and the lower steel ring is fixedly mounted on a lower side plate. The lower chuck is connected with the lower steel ring by the transition disc; the lower steel ring is directly and fixedly mounted on the lower side plate; the transition disc and the lower chuck are hoisted along with the vulcanizing machine central mechanism; firstly, the transition disc does not need to be detached when tyres with the same size and different specifications are vulcanized, and only the lower steel ring and the lower side plate need to be replaced; the operation is simple, the time and labor are saved and the utilization rate of workpieces is high; and secondly, the matched part of the lower steel ring and the lower side plate is intact and lossless, and the vulcanized tyres do not have the defects of rubber edges or bulges so that the quality of the tyres is guaranteed.

Example Embodiment

[0011] In order to clearly illustrate the technical characteristics of this solution, the following describes the present invention in detail through specific implementations and in conjunction with the accompanying drawings.
[0012] Such as figure 2 As shown, an active mold for a tire building vulcanizing machine includes a lower chuck 2 and an upper chuck 3 respectively connected to the central mechanism 1 of the vulcanizer. The lower chuck 2 and the upper chuck 3 are respectively connected to the transition plate 4 and The upper steel ring 5 is fixedly connected, the lower chuck 2 and the transition disk 4 clamp the bottom clamping edge of the capsule 6, and the upper chuck 3 and the upper steel ring 5 clamp the top clamping edge of the capsule 6. Steel ring 7, the bottom edge of the transition plate 4 and the lower steel ring 7 are mated and oppositely connected. The lower steel ring 7 is fixedly installed on the lower side plate 8, and the lower side plate 8 is then installed on the base table panel 9. When the tire is vulcanized, the water cylinder of the central mechanism 1 of the vulcanizer is extended, the superheated water in the bladder 6 is discharged, the bladder 6 is stretched, and then the lower chuck 2 and the transition disk 4 are lifted to remove the tire from the mold , And then the unloading trolley drags the tires, the central mechanism 1 of the vulcanizer lowers the water tank to reset, and the trolley turns the tires onto the conveyor belt. Connect the lower chuck 2 and the lower steel ring 7 through the transition plate 4, and the lower steel ring 7 is directly fixed and installed on the lower side plate 8. The transition plate 4 and the lower chuck 2 are lifted and lowered together with the central mechanism 1 of the vulcanizer. When vulcanizing tires of the same size and different specifications, there is no need to disassemble the transition disc 4, just replace the lower steel rim 7 and the lower side plate 8. The operation is simple, time-saving and labor-saving, and the utilization rate of the workpiece is high. 2 During the lifting process of the central mechanism 1 of the vulcanizing machine, even if the mating part of the transition disk 4 and the lower steel ring 7 is worn and bruised, the mating part of the transition disk 4 and the lower steel ring 7 is located inside the lower steel ring 7. It will be in direct contact with the tire and will not affect the quality of the tire. However, this design allows the lower rim 7 to be fixedly installed on the lower side plate 8, ensuring that the joint between the lower rim 7 and the lower side plate 8 is intact. 7 The matching place with the lower side plate 8 will directly contact the tire, and the tire will not have defects such as rubber edges or bumps after vulcanization, which ensures the quality of the tire.
[0013] The above-mentioned specific implementation manners should not be regarded as a limitation to the protection scope of the present invention. For those skilled in the art, any alternative improvements or changes made to the implementation manners of the present invention fall within the protection scope of the present invention.
[0014] Anything not described in detail in the present invention is the well-known technique of those skilled in the art.
