Novel secondary-class structure shock insulation support vulcanization mould

Abstract

The invention discloses a novel secondary-class structure shock insulation support vulcanization mould, which comprises an upper mould, forming blocks, a lower mould and a central spindle, wherein twoforming blocks are arranged between the upper mould and the lower mould and are respectively provided with a semicircular inner cavity; two sides of each forming block are respectively fixedly provided with a connecting sheet; the two forming blocks are fixedly connected through the connecting sheets and bolt bars; slot positions used for containing the forming blocks are respectively arranged inthe upper mould and the lower mould; the central spindle is inserted into hole positions on the center of a circle of the upper mould and the lower mould; a glue discharging block is also arranged inthe hole position of the lower mould. The novel secondary-class structure shock insulation support vulcanization mould has the beneficial effects of simple structure, reasonable design, good use effect, good vulcanization performance, good product integrality, simple and attractive structure construction, material saving, high repeated use ratio and long service life.

Description

technical field [0001] The invention is a novel vulcanization mold for a second-class building shock-isolation support. Background technique [0002] At present, the known manufacturing method of the rubber shock-isolation bearing used for building shock-isolation is to stack the thin rubber layer and the thin steel plate layer, and there are holes in the middle of the thin rubber layer and the thin steel plate layer, and insert radially positioned steel rods ( Mandrel), the whole is put into a steel mold and molded by high temperature and pressure vulcanization. The mold generally consists of a ring-shaped outer mold, a columnar radially positioned steel rod inner mold, and upper and lower molds. The manufacturing method and mold are suitable for manufacturing natural rubber shock-isolation supports, high-damping rubber shock-isolation supports, lead-core rubber shock-isolation supports and other rubber shock-isolation supports. However, due to various factors such as tim...

Problems solved by technology

However, due to various factors such as time-consuming unloading, cumbersome operation, and uneven vulcanization due to uneven temperature in various parts of the internal rubber vulcanization, the rubber shock-isolating bearing produced by this manufacturing method and mold is produced. It is difficult to ensure that the bearing has a beautiful appearance. Under the action of vertical pressure, the bearing often lacks rubber, which affects the quality of the rubber seismic bearing.
