Description

Automobile core rod die with optimized exhaust performance Technical Field The utility model relates to the technical field of automobile core rod dies, in particular to an automobile core rod die with optimized exhaust performance. Background The automobile core rod is a precision molding part in key components such as an automobile engine, a gearbox and the like, is generally manufactured by adopting a die casting process and is used for forming a complex internal cavity structure, in the die casting process, the function of an exhaust system is important, the automobile core rod can effectively exhaust air in a cavity and gas brought by metal liquid, the defects of air holes, cold insulation and the like are avoided, the smoothness of metal liquid filling is ensured, and the compactness of castings is improved. However, the vent hole of the traditional die is easy to cause flaws on a workpiece, when molten raw materials easily permeate into the vent hole channel under high pressure to form flash, the workpiece needs to be polished later, the aperture of the vent hole channel is usually smaller to reduce the flaws, but the vent hole channel with smaller aperture causes slower air discharge speed of a cavity to affect the working efficiency, and in view of the problems, the application provides the automobile core rod die with optimized vent performance. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides an automobile core rod die with optimized exhaust performance. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides an automobile core rod mould with optimize exhaust performance, includes the base, the top surface sliding connection of base has the footstock, the top surface fixed mounting of base has the bed die, the bottom surface fixed mounting of footstock has the mould, install ejection mechanism in the bed die, the top surface of going up the mould is fixed and the intercommunication has the intercommunication seat, the outside of intercommunication seat is fixed and the intercommunication has a plurality of blast pipes, a plurality of the blast pipes are fixed jointly and the intercommunication has the ring canal, sealing sliding connection has first closing plate in the intercommunication seat, the top fixed mounting of intercommunication seat has first electric telescopic handle, and the bottom of first electric telescopic handle and the top surface fixed connection of first closing plate, the subassembly of breathing in is installed to the top surface of footstock, and the subassembly of breathing in is linked together with the ring canal.
