Vulcanized mould for secondary-class building seismic isolation support

Abstract

The invention discloses a vulcanized mould for a secondary-class building seismic isolation support. The mould comprises an upper mould, a lower mould, two molding blocks, rubber discharging blocks, hoisting blocks and a mandrel, wherein the hoisting blocks are arranged surrounding the outer parts of the upper mould and the lower mould; the upper mould and the lower mould are connected through the molding blocks; the two molding blocks are connected through a bolt rod; the rubber discharging blocks are arranged on the upper mould and the lower mould; and the two ends of the mandrel are respectively connected with the rubber discharging block of the upper mould and the rubber discharging block of the lower mould. The mould has a simple structure, is reasonable in design, is simple and convenient to operate, has good vulcanizing property, has good integrity and use security, is attractive in appearance, is convenient to separate and replace, costs less time and saves materials; the mould is high in repeating utilization ratio, low in using cost, and long in service life; and the manufactured support has higher quality and can meet production demands of people.

Description

technical field [0001] The invention relates to a mold, in particular to a vulcanized mold for a second-class building shock-isolation bearing. Background technique [0002] At present, the known manufacturing method of the rubber seismic isolation bearing used for building seismic isolation is to stack a thin rubber layer and a thin steel plate layer, and there is a hole 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, the rubber...

Problems solved by technology

However, the rubber shock-isolating bearing produced by this manufacturing method and the mold has the following disadvantages: first, it is time-consuming when unloading the mold; second, the operation is cumbersome; , leading to uneven vulcanization, it is difficult to ensure that the rubber bearing has a beautiful appearance, and under the action of vertical pressure, the bearing often lacks glue, which affects the performance of the rubber bearing quality, which brings inconvenience to people's use
