Abstract
The utility model relates to cast cleaning devices.Upper cavity and lower chamber fasten internal formation airtight cavity, and lower chamber connects compressed air inlet port, and upper cavity is equipped with exhaust outlet and pressure gauge, and the lower pointed tooth being arranged side by side is equipped with inside lower chamber, is equipped with upper pointed tooth arranged side by side inside upper cavity.The silica sand of casting exterior is under Condition for expansion, and silica sand cracking is loose, and upper pointed tooth, lower pointed tooth make molding sand further crack, and molding sand more easily removes cast(ing) surface.Multiple casting can be handled simultaneously, and work efficiency is high；Avoid damage of the impact force to casting；Worker's working strength is reduced simultaneously.
Description
Technical field
The utility model relates to cast processing unit (plant) technical field, and in particular to a kind of cast cleaning device.
Background technique
After the completion of present Foundry Works casting, need to carry out sand removal work to casting, existing frequently-used sand removal mode is first to use
Artificial hammer taps casting, loosens the molding sand in casting by the vibration of casting and falls, then removes molding sand with compressed air and do
Only, achieve the effect that remove molding sand, this mode worker's great work intensity, efficiency is lower, and there are security risks, especially to some
Spherical, cylindrical casting is difficult fixed casting, while grasping because manually tapping dynamics difficulty, is easy to damage casting, sand removal
Effect is undesirable.
Utility model content
Purpose of the utility model is to solve the above problems and provide a kind of structures to be simple and convenient to operate, shakeout is high-efficient
Cast cleaning device.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
Cast cleaning device, including upper cavity 1 and lower chamber 2, upper cavity 1 and lower chamber 2 fasten internal formation closed chamber
Body, lower chamber 2 connect compressed air inlet port 21, and upper cavity 1 is equipped with exhaust outlet 22, and exhaust outlet 22 is equipped with exhaust valve and pressure
Power table 23, which is characterized in that be equipped with pointed tooth 3 under semicircle arranged side by side inside lower chamber 2, lower pointed tooth 3 upward, upper cavity
1 inside is equipped with pointed tooth 4 in semicircle arranged side by side, and downward, upper 4 top of pointed tooth is equipped with compression bar 5 to pointed tooth 4 thereon, and compression bar 5 runs through
Upper cavity 1, the junction between compression bar 5 and upper cavity 1 are equipped with sealing ring 6, and screw buckle connects between compression bar 5 and upper cavity 1, pressure
Rotating handle is equipped at the top of bar 5.
Optimization, exhaust outlet 22 connect rubber air bag 7, and rubber air bag 7 is equipped with leakage port 71.
Working principle of the utility model is:
Casting is put into 4 top of upper pointed tooth of lower chamber 2, fastens lower chamber 2, and casting is set in airtight cavity, is passed through compression
Air makes cavity internal pressure reach 0.5MPa or more, and then moment opens exhaust valve, makes to form pressure difference, casting in airtight cavity
The molding sand on surface is loosened since pressure drop extruding cracks.Compression bar is rotated down, and upper pointed tooth 4 is pressed down against casting, and lower pointed tooth squeezes upwards
Die casting makes the molding sand of cast(ing) surface further crack, and molding sand more easily removes cast(ing) surface.
Compared with prior art, the advantages of the utility model are as follows:
The silica sand of casting exterior is under Condition for expansion, and silica sand cracking is loose, and upper pointed tooth, lower pointed tooth open molding sand further
It splits, molding sand more easily removes cast(ing) surface.Multiple casting can be handled simultaneously, and work efficiency is high；Impact force is avoided to casting
Damage；Worker's working strength is reduced simultaneously.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
