Four layers circulating type hydraulic pressure vulcanizing machine

Abstract

The present invention relates to a four-layer circulated hydraulic pressure vulcanizing machine, and concretely the vulcanizing machine is used for vulcanizations of macromolecular materials such as rubber and plastic and especially is fit for the vulcanization of an inner tube of the tyre industry. The vulcanizing machine is characterized in that a double-stage oscillating cylinder and a single-stage oscillating cylinder are respectively fixed at a lower crossbeam; single-direction bearings are pressed into a driving chain wheel and respectively enclosed into the double-stage oscillating cylinder and the single-stage oscillating cylinder; driven chain wheels are respectively installed at the lower cross beam; a double-stage traction chain and a single-stage traction chain are respectively linked with the driven chain wheel; a lower-pressing standing post whisks into a plane bearing, a lifting plate and a hole of the lower crossbeam to be axially slip linked with the driven chain wheels; a lower-pressing accessory oil cylinder is installed on a floating board; an upper nipping hot board and an upper hot board are installed under the floating board and are linked with a piston rod of the lower-pressing accessory oil cylinder. The present invention can realize opening and closing a mould and costs little energy with a small occupied area and can lighten the labor intensity of the operators.

Description

technical field [0001] The invention relates to a four-layer circulating hydraulic vulcanizing machine, which is specifically used for vulcanizing polymer materials such as rubber and plastics, and is especially suitable for vulcanizing inner tubes in the tire industry. Background technique [0002] In the prior art, vulcanizers generally have two types, four-column type and cabinet type, and the number of working layers is mostly 1-3 layers. Because of the biggest characteristic of inner tube vulcanization, the product parts are thin and the vulcanization cycle is short. To achieve multi-layer vulcanization, the process conditions cannot be achieved. One, two, three, and four layers of mold closing will produce eight time differences from the first layer to the fourth layer, and the vulcanization time is calculated in seconds, so that the product of the first layer is either burnt out or the product of the fourth layer Lack of sulfur seriously affects the quality of its pr...

Because of the biggest characteristic of inner tube vulcanization, the product parts are thin and the vulcanization cycle is short. To achieve multi-layer vulcanization, the process conditions cannot be achieved. One, two, three, and four layers of mold closing will produce eight time differences from the first layer to the fourth layer, and the vulcanization time is calculated in seconds, so that the product of the first layer is either burnt out or the product of the fourth layer Lack of sulfur seriously affects the quality of its products, so it can only use multiple equipment on the first to second floors to meet its output, and multiple equipment will inevitably result in a large area, high energy consumption, and labor-intensive operators.
