Hydraulic automatic clamping mold

Abstract

The invention discloses a full-automatic hydraulic mold-clamping mold. The mold comprises annular seats, wherein disk-shaped molds are arranged inside the annular seats; annular inner cavities are formed in the disk-shaped molds; a middle barrel is vertically arranged in the middle of the molds; the middle part of the middle barrel is communicated with the annular inner cavities through annular notches; a cylinder piston rod at the bottom of the middle barrel extends into the middle barrel; a disk-shaped lower supporting base and an disk-shaped upper supporting base are arranged on the piston rod; the lower supporting base is propped against the bottom of the annular notches in the middle of the middle barrel; the upper supporting base is used for supporting the top of the annular notches in the middle of the middle barrel; clamping rings are mounted outside the annular seats in a concentric and sleeving way; a plurality of flanges extending into the clamping rings are formed in annular walls of the molds; a slide seat is fixed on each of the top of each flange and the inner annular wall at the top of each clamping ring; clamping blocks are arranged among the slide seats in a sliding way; a plurality of pressurized hydraulic cylinders are arranged on the outer walls of the clamping rings; and the piston rod of each pressurized hydraulic cylinder extends into each clamping ring and points to the clamping block on the corresponding flange.

Description

technical field [0001] The invention relates to the field of clamping molds, in particular to a hydraulic fully automatic clamping mold. Background technique [0002] During the tire processing process, the mold used to form the tire needs to be locked by the clamping device. Some of the prior art adopts the mode of screw fixing to lock the mold, and the screw needs to be loaded and unloaded in the use process, which is time-consuming and labor-intensive. There is also a mold that uses high-pressure water to lock the mold. During its use, sealing rings need to be installed on the inner and outer rings of the mold. Since it is in a vulcanized state for a long time, the sealing ring will be vulcanized along with the tire, and aging will occur after a long time of use. And the problem of poor sealing performance, resulting in thicker rubber edge of the tire. Contents of the invention [0003] Problems existing in the prior art. The invention provides a hydraulic automatic ...

AI Technical Summary

Problems solved by technology

Some of the existing technologies use screws to fix the mold, and the screws need to be installed and removed during use, which is time-consuming and labor-intensive.

There is also a mold that uses high-pressure water to lock the mold. During its use, sealing rings need to be installed on the inner and outer rings of the mold. Since it is in a state of vulcanization for a long time, the sealing ring will be vulcanized together with the tire, and it will age when it is used for a long time. and poor sealing performance, resulting in thicker rubber edges of tires
