Description
Technical Field
The utility model relates to a casting core making machine technical field especially relates to a novel sand shooting mechanism of core making machine.
Background
The core making machine is one of important equipment for core sand molding in the casting industry, and the working principle is as follows: the core making machine drives all parts of the core box to open and close, and the mixed core sand is shot into the core box through compressed air; subsequently, the catalytic gas is introduced into the core box, and the core sand is hardened in a short time to meet the process and production requirements and ejected and removed from the core box.
The problem that prior art exists is mainly, at the in-process that compressed air jets into the core box with the core sand that has mixed, seals shooting barrel through the apron, because the tectorial membrane sand is the dry and scattered graininess, it is serious just to run sand a bit of gap, and conventional means is sealed the gap of baffle through adding to establish the sealing washer, and the sealing washer is very damaged with the tectorial membrane sand under the impact of air current, and damaged sealing washer also runs sand very easily. The sand running not only influences the working environment of workers, but also greatly improves the production cost.
Disclosure of Invention
An object of the utility model is to prior art not enough, and provide a novel sand shooting mechanism of core making machine, it seals the intercommunication mouth that advances of shooting a sand section of thick bamboo through the sealed awl of cylinder drive back taper structure, and is sealed effectual, the effectual sand that runs that has prevented.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel sand shooting mechanism of core making machine, includes a sand section of thick bamboo, a sand section of thick bamboo comprises sand section and sand shooting section, sand section with be provided with the intercommunication mouth between the sand shooting section, sand section of thick bamboo upper portion is provided with the cylinder, the telescopic shaft of cylinder runs through sand section with sand shooting section, the fixed sealed awl that is provided with the back taper structure of lower extreme of telescopic shaft, sealed awl with the intercommunication mouth is inconsistent, sand section and sand hopper intercommunication, sand shooting section lateral part is provided with admission valve and discharge valve, the bottom of sand shooting section is provided with penetrates the mouth.
Preferably, the sand adding hopper is communicated with the sand adding hopper through a sand adding pipe, and a gate plate is arranged at the bottom of the sand adding hopper.
Preferably, a return spring is arranged between the sealing cone and the nozzle, and if the air is stopped or the sealing cone breaks down and is in an open state, the sealing cone can be reset under the action of the return spring to seal the additional communication port.
Preferably, the sand adding section is positioned above the sand shooting section, and the sand adding section and the sand shooting section are separated by a partition plate.
The utility model has the advantages that: the utility model provides a novel sand shooting mechanism of core making machine, including a sand section of thick bamboo, a sand section of thick bamboo comprises sand section and sand shooting section, sand section and sand shooting section realize the grit separation, the two is sealed through the sealed awl of back taper structure, the cylinder piston moves down when sand is added to the sand shooting section, sealed awl is opened, the grit gets into sand shooting section lower part, add sand and finish, the cylinder air inlet is closed, the piston shifts up under compressed air and reset spring effect, sealed awl is sealed and is added the intercommunication mouth, make sand shooting section upper and lower two parts grit part separately, it is sealed effectual, equipment surface cleaning is clean, no sand running phenomenon has created good operational environment for the workman simultaneously.
