Internal and external synchronous heating type shock insulation rubber support die

Abstract

The invention discloses an internal and external synchronous heating type shock insulation rubber support die. The internal and external synchronous heating type shock insulation rubber support die comprises a die body. The die body comprises multiple die plates, an upper flange plate, a lower flange plate, core rods and multiple framework plates. The upper flange plate, the lower flange plate andthe multiple die plates cooperate to define a die cavity, the lower ends of the core rods are connected with the lower flange plate, the upper ends of the core rods are connected with the upper flange plate, the framework plates are connected to the core rods in a sleeving manner, the multiple framework plates are evenly distributed in the die cavity at intervals, electromagnetic heaters are arranged on the outer walls of the core rods, the die plates are of hollow structures, passageways are formed in the die plates, and a circulating heat conducting medium flows in the passageways. The electromagnetic heaters are arranged in the die cavity and cooperate with the circulating heat conducting medium of the peripheral die plates for heating, the phenomena that the periphery and the upper face and the lower face of a shock insulation rubber support are over-cured, and an inner core is still raw can be effectively avoided, and the product quality is effectively improved.

Description

technical field [0001] The invention relates to a mould, in particular to an inner and outer synchronous heating type shock-isolation rubber bearing mould. Background technique [0002] With the large-scale construction of highways and railway bridges in our country, as well as the reconstruction work after major earthquakes in some areas of the country, the use of seismic isolation rubber bearings as a major component of earthquake resistance for bridges and building buildings has also increased sharply. [0003] At present, during the vulcanization and molding process of the vibration-isolation rubber bearing, the phenomenon that the periphery and the upper and lower sides of the vibration-isolation rubber bearing are prone to overvulcanization, and the inner core of the vibration-isolation rubber bearing is not cooked, therefore, urgently needs to be solved. Contents of the invention [0004] The purpose of the present invention is to solve the above problems and provid...
