End thread circle driving mechanism for die locking pressing plate

Abstract

The invention discloses an end thread circle driving mechanism for a die locking pressing plate. The end thread circle driving mechanism for the die locking pressing plate comprises an installation base body, a rod body and a gear ring. The installation base body is fixedly connected to a die or extends outwards from the die in the radial direction of the die, and a through hole perpendicular to the installation direction of the installation base body is formed in the installation base body. One end of the rod body is driven by external driving force so that the rod body can rotate in the axial direction of the rod body. The other end of the rod body penetrates through the through hole. A plurality of racks are further arranged on the side surface of the other end of the rod body in the axial direction of the rod body and distributed in the circumferential direction of the rod body at intervals. The side face of the gear ring is engaged with the racks of the rod body. The gear ring is driven by the rod body to move in the circumferential direction. The bottom of the gear ring is further matched with the die locking pressing plate in a threaded mode. Compared with the prior art, die locking of the die locking pressing plate can be achieved to the maximum extent; meanwhile, die locking synchronization of all die locking pressing plates can also be kept through unified external driving force under the condition that the multiple die locking pressing plates exist, and the overall die locking effect is improved.

Description

technical field [0001] The invention relates to a mold clamping mechanism used in the field of tire vulcanization equipment, in particular to an end face threaded ring driving mechanism used for mold clamping and pressing plates. Background technique [0002] In current tire vulcanizing equipment, the connection between the hot plate and the upper and lower molds is usually accomplished by means of screw connection. In order to facilitate the connection between the two, there is currently a clamping platen, which is installed on the grooves and protrusions in the form of U-shaped, E-shaped and other shapes of clamping platen. figure 1 Shown is a U-shaped clamping platen structure, the mold 1 is provided with a protrusion 11, and the hot plate 2 is provided with a groove 21, and the clamping platen 3 is clamped to the protrusion 11 and the groove 21 superior. [0003] However, in the use of the clamping platen, we also found that, through such as Figure 1-2 The mode of p...

[0003] However, in the use of the clamping platen, we also found that, through such as Figure 1-2 The mode of pushing the mold clamping platen by hand or locking the mold by screw 4 is all done by manpower, so it is difficult to fully lock the mold clamping platen into the mold and the hot plate, and when the mold When it is necessary to set up multiple clamping platens, the locking conditions between each clamping platen will cause asynchrony, so that the effect of the entire mold clamping is not good.
