Embodiment Construction
[0012] The present invention will be further described below in conjunction with drawings and embodiments.
[0013] Such as figure 2 As shown, a positioning sleeve for the central mechanism of a vulcanizing machine includes an upper platen 1 , a lower clamping plate 2 , a capsule 3 , a cylinder 4 and a positioning sleeve 5 .
[0014] Such as figure 2 As shown, the lower clamping plate 2 is fixed on the vulcanizer 6, the upper clamping plate 1 is arranged above the lower clamping plate 2, and it and the lower clamping plate 2 are arranged along the horizontal direction; the capsule 3 is cylindrical, and its two ends are respectively sealed and connected to the upper clamping plate 1 , On the lower clamping plate 2, the capsule 3, the upper pressing plate 1, and the lower clamping plate 2 form an airtight air bag chamber 31.
[0015] The cylinder body 41 of cylinder 4 is installed on the side of lower clamping plate 2 away from capsule 3, as figure 2 As shown, the piston r...

The invention discloses a positioning sleeve for a vulcanizing machine center mechanism. The problems that an existing positioning sleeve is poor in applicability, high in manufacturing difficulty andhigh in production cost are solved. An upper pressing plate is horizontally arranged above a lower clamping plate in a spaced mode, the two ends of a capsule are in sealed connection with the upper pressing plate and the lower clamping plate, a piston rod of an air cylinder penetrates through the lower clamping plate to extend into the capsule and is connected with the upper pressing plate, the positioning sleeve comprises a first supporting sleeve, a second supporting sleeve and two positioning copper sleeves arranged on the piston rod in a sleeving mode, and the first supporting sleeve andthe second supporting sleeve are in threaded connection. The free ends of the first supporting sleeve and the second supporting sleeve are provided with containing cavities. The positioning copper sleeves are fixed in the containing cavities and are in sliding connection with the piston rod. The connection length of the first supporting sleeve and the second supporting sleeve is changed through threaded connection between the first supporting sleeve and the second supporting sleeve, and therefore production requirements of base bodies with different heights can be met. The positioning sleeve is good in applicability, low in manufacturing difficulty and low in production cost.
Description
technical field [0001] The invention relates to equipment used for rubber vulcanization, in particular to a positioning sleeve for a central mechanism of a vulcanizing machine. Background technique [0002] We know that the central mechanism of the tire vulcanizing machine is also called the bladder control mechanism, and its main function is to extend into the interior of the tire blank to shape the carcass and maintain the curing environment. At present, the central mechanism of a tire vulcanizer usually includes a horizontally arranged upper platen, a horizontally arranged lower clamping plate, a bladder sealed and connected between the upper platen and the lower platen, and a vertically arranged air cylinder, wherein the cylinder of the air cylinder The body is fixed on the lower clamping plate, and the piston rod of the cylinder penetrates the lower clamping plate into the capsule and is connected with the upper pressing plate. The piston rod of the air cylinder is tel...
