Mold locking mechanism of dual-mold vulcanizing machine

Abstract

The invention discloses a mold locking mechanism of a dual-mold vulcanizing machine. The mold locking mechanism comprises a sector-shaped inner gear, a sector-shaped outer gear, a guiding shaft and a poking rod, wherein the sector-shaped inner gear is fixed on a cross recess base; the sector-shaped outer gear is meshed with the sector-shaped inner gear; the lower end of the guiding shaft is fixedly connected with the sector-shaped outer gear; one end of the poking rod is provided with a sleeve; the guiding shaft is arranged in the sleeve; the other end of the poking rod is provided with a handle; the guiding shaft can slide up and down in the sleeve and is connected with the sleeve by a guiding flat key; the upper surface and the lower surface of the sector-shaped inner gear are respectively provided with a limiting plate; and the sector-shaped outer gear is clamped by the two limiting plates which are in sliding contact with the surface of the sector-shaped outer gear. The mold locking mechanism disclosed by the invention has the advantages that the structure is simple, and the installation and the debugging are easy; all part supports do rotating and lifting movement, no translation is caused, and the wear among parts is small, so that the service life is long and the movement accuracy can be maintained at a relatively high level all the time; and the locking is in place, so that the probability of falling of molds is reduced.

Description

technical field [0001] The invention relates to a locking mechanism, in particular to a mold locking mechanism of a double-mode vulcanizer. Background technique [0002] In the current existing technology, the clamping mechanism of the hydraulic double-mode vulcanizer adopts the relative movement of the cross chuck and the cross groove seat, and locks the cross chuck and the cross groove seat to realize the connection and locking of the mold and the oil cylinder. . Because the cross chuck is connected with the mold, the cross chuck is fixed, and the guide shaft on the cross groove seat is moved by the fork to make the cross groove seat rotate, so as to realize the locking of the chuck and the groove seat and the movement of the guide shaft The track is a circular arc. In order to ensure the connection between the shift fork and the guide shaft, a long groove is arranged in the middle of the shift fork, and the fixed shaft of the shift fork is installed in the long groove. ...

AI Technical Summary

Problems solved by technology

[0003] This kind of mold locking mechanism has complex structure, many moving parts, difficult debugging, it is more laborious to pull the shift fork, each part is prone to wear and tear, and it is easy to cause the locking not in place, and there is a danger of mold falling off during production.

Since the guide shaft moves up and down with the cross groove seat, only one section of the guide shaft is fixed. When the fork moves the guide shaft, the guide shaft is also prone to bending or even bending, which affects the locking accuracy or causes damage.
