Fig. 5 shows the vulcanizer that the utility model proposes with the form of semi-section;

Fig. 6 is a cross-sectional view of the diaphragm device in the vulcanizing machine proposed by the present invention.

As shown in Figures 5 and 6, the diaphragm vulcanizer of the present invention includes a frame member 30, a diaphragm device 33, an upper steam cabinet 31, a middle steam cabinet 32, a lower steam cabinet 34, a hydraulic device 35 and a pipeline system. The frame member 30 is formed by fastening an upper supporting plate 301 , a base 302 and a column 303 through keys and bolts. The diaphragm device 33 is connected between the upper and lower steam cabinets 31, 34 and includes telescopic cylinders, upper and lower pressure pads, capsules, and moulds, and its specific structure will be described later. The lower end of the capsule 3 is fixed on the hot plate 29 of the lower steam cabinet, the upper end of the capsule 3 is fixed on the top of the telescopic cylinder, and the telescopic control of the plunger in the telescopic cylinder realizes shrinkage, straightening, vacuuming, shaping and other technological requirements of the capsule. Telescopic cylinder is also fixed on the hot plate of lower steam cabinet 34. Molds 1,2 are respectively fixed in upper and lower steam cabinets 31,34. Lower steam cabinet 34 is connected with the oil cylinder plunger of hydraulic device 35 by a push plate. The oil cylinder is fixed in the base. When the vulcanizer of the utility model is working, a certain pressure of oil is injected into the oil cylinder through the hydraulic station, so that the plunger supports the lower steam cabinet 34 and rises vertically to realize the processes of mold closing, inflation and pressurization, shaping, and vulcanization. After the vulcanization is completed, the plunger is retracted, the mold is opened, and the middle steam cabinet descends by its own weight, and finally stops on the equidistant positioning plate. The tire can be removed by pulling it out from the tire. Reinstall the new embryo, the oil cylinder works, the mold is closed, the telescopic cylinder is lowered, the bladder shrinks into the tire, and then the next process is completed by inflating and shaping, closing the membrane, reshaping, and vulcanizing.

Since the cooperation between the mold and the steam cabinet and the driving of the hydraulic device to the steam cabinet belong to the prior art, it will not be described in detail, and only the novel diaphragm device proposed by the utility model will be described in detail below.

Fig. 6 shows a cross-sectional view of the diaphragm device of the present invention, and its left and right parts respectively show two states of the diaphragm device. Its left half is the closed mold state, wherein the plunger of the telescopic cylinder does not stretch out and the capsule shrinks; its right half (upper mold is not shown) is the open state, wherein the plunger of the telescopic cylinder stretches out Whereas the capsule is straightened.

The telescopic cylinder is composed of a cylinder block 16, a lower plunger 17, and an upper plunger 19 located in the lower plunger 17. The sealing rings 20, 21, and 22 are respectively used to ensure that the cylinder block, the upper and lower plungers and the hot plate 29 of the steam cabinet and the sealing between them. The gland 14 covers the cylinder block 16 and is fixed thereon by screws 15 . Screw 13 fixes the whole telescopic cylinder on the lower steam cabinet hot plate 29. The upper mold 2 and the lower mold 1 are respectively fixed on the hot plate 29 of the upper and lower steam cabinets. The capsule 3 positioned in the mold has an upper end and a lower end, and its lower end is sandwiched between a lower backing plate 5 and a lower pressing plate 4 and is fixedly connected with them by bolts 27 and nuts 28 . Stud bolt 23, nut 24 are fixed on the lower steam cabinet hot plate 29 of the lower end of capsule 3 and lower pressing plate and lower backing plate. The lower pressing plate 4 cooperates with the lower mold 1 to be compressed on the hot plate 29 of the steam cabinet through an inclined plane. The interior of the lower backing plate 5 is provided with a channel communicating with the interior of the bladder for supplying the medium required in the vulcanization process. The rubber ring 12 is used to ensure the sealing between the lower backing plate 5 and the steam cabinet backing plate 29 . The upper end of the capsule 3 is clamped between the upper backing plate 6 and the upper pressing plate 7, and the upper backing plate 6 is fixed on the top of the upper plunger 19 by bolts 18. After the lower plunger 17 and the upper plunger 19 stretch out from the cylinder body 16, the upper end of the capsule 3 moves up thereupon, so that the capsule is pulled out from the embryo (not shown in the figure) due to being straightened (see Fig. 6 right side part), and when the upper and lower plungers are retracted in the cylinder block 16. The upper end of the capsule 3 descends, and the capsule retracts so that it can just penetrate into the newly placed embryo (not shown in the figure) (see the left part of Fig. 6). The upper mold 2 is pressed against the upper pressing plate 7 through an inclined surface. The backing plate bushing 11, screw 10, bushing 9 and pressing block 8 on the upper pressing plate 7 form a quick loading and unloading pressing plate device, which can be quickly removed by turning the quick loading and unloading pressing block 8, unscrewing the bolt 18 and the nut 24. Press the backing plate down, and then the capsule 3 can be unloaded very conveniently and quickly. The sealing ring 25 is arranged between the upper and lower pressure plates, and is used to ensure the sealing when the two plates cooperate.

Tests have proved that the utility model has the following advantages compared with the prior art:

1. Compact structure and low production cost. Compared with the four-mode tire shaping vulcanizing machine with the same production capacity, the volume can be reduced by two-thirds, the weight can be reduced by two-thirds, and the cost can be reduced by two-thirds.

2. High production efficiency. Compared with the bladder three-layer vulcanizing machine, it can realize the internal shaping of the tire and the automatic loading and unloading of the bladder, so the additional equipment is omitted, the time used for a process is shortened, and the safety of production is improved at the same time.

3. The service life of the capsule can be extended and the replacement of the capsule becomes very easy.

Although the utility model has been described above by the form of the embodiment. But the utility model is not limited thereto, and those skilled in the art can also improve, modify or improve it within its spirit and scope.
