Description

A kind of knock-out barrel collected convenient for molding sand
Technical field
The present invention relates to Casting Equipment field, specially a kind of knock-out barrel collected convenient for molding sand.
Background technique
Casting is a kind of common metal heat processing technique, i.e., by Metal Melting at pouring into the casting made of molding sand after liquid In mould, after liquid metals in the type chamber in mold after cooled and solidified, in order to obtain casting, need molding sand from cast(ing) surface point It leaves and, existing method is the vibration generated using shakeout and impact to complete knockout, compared to vibrating type sand-dropping machine, rolling There is cylinder shakeout dust and noise to be easy to control, the good advantage of working condition, therefore application is more and more extensive, but in roller knockout In the process, casting is difficult to cool down, and the molding sand fallen from casting is difficult to collect.
Summary of the invention
The purpose of the present invention is in view of the above problems, provide it is a kind of convenient for molding sand collect knock-out barrel, be easy to collect Molding sand is convenient for casting mold cooling simultaneously.
In order to achieve the above object, the technical solution adopted by the present invention is that: it includes pedestal, pedestal upper center interval It is provided with support base, is provided with roller above the support base, the roller both ends open, wherein one end is set as feed end, The other end is set as discharge end, and internal screw thread is provided on the inner wall of rotary drum, and the pedestal upper end is provided with for driving roller The driving mechanism rotated;Clearance hole is disposed in discharge end side on the cylinder wall;The support base upper end It is provided with the outer tube of both ends open, the roller is set in outer tube, is provided with axis between the cylinder outer wall and outer tube wall It holds, external screw thread is provided on the cylinder outer wall, the externally threaded outer diameter is adapted with outer tube diameter, the internal screw thread and outer Screw thread it is oppositely oriented, the outer tube bottom wall is provided with clearance hole in the distal side of discharge end;The pedestal upper end is open in outer tube End two sides are provided with bracket, the ventilation duct of inner hollow are provided between two side stands, the ventilation duct passes through roller, described logical Spray head is disposed on air hose side wall in one section in roller, the spray head passes through the discharge pipe and ventilation duct on ventilation duct side wall Inside connection.
Further, the pedestal upper end is provided with discharging guide plate below roller discharge end.
Further, the outer tube lower end is provided with sediment outflow bucket in the exit of clearance hole.
Further, outer diameter is greater than both ends outer diameter in the middle part of the ventilation duct.
Further, a circle is provided on the ventilation duct side wall for protecting the protection ring of spray head.
Further, the cross section of the protection ring is minor arc shape, and the spray head is located on the inside of protection ring.
Further, air guide ring is provided on the ventilation duct side wall, the air guide ring cross section is arc, air guide ring end It holds to inner wall of rotary drum and extends, and air guide ring is stacked with protection ring, the spray head is between air guide ring and protection ring.
Further, it is provided with siding on the inner wall of rotary drum, the siding is along roller axially setting and to the axis of roller Line extends.
Further, the roller discharge end internal diameter is less than feed end internal diameter, and inner wall of rotary drum is to justify in discharge end side Taper.
Beneficial effects of the present invention: the casting mold of cooled and solidified enters in roller from feed end, then under the drive of driving mechanism Roller starts turning, and casting mold rolls along internal screw thread to advance, and during rolling, casting mold is ceaselessly collided with cylinder wall, from And molding sand is fallen down from casting;When casting mold moves to roller discharge end side, the molding sand that is separated from casting from Clearance hole is fallen in outer tube, by pushing on cylinder outer wall with the oppositely oriented external screw thread of internal screw thread, so that molding sand and casting It separates and towards charging end motion, it is unified after the external screw thread of cylinder outer wall rolls to be dropped out from clearance hole, convenient for collecting molding sand.
1, ventilation duct passes through roller, and the air-flow of the generations such as air blower is sprayed along ventilation duct from spray head, uses air-cooled for casting Type cooling reduces water resource and utilizes compared to common water-spraying control mode, it is easier to which it is raw to reduce enterprise for later collection molding sand Produce cost;Casting strikes spray head in the process of movement in order to prevent, is provided with protection ring in pipe outer wall of divulging information, spray head is located at The inside of protection ring, to avoid being knocked, and protection ring is set as arc, and the impact resistance energy of protection ring is improved by arc Power;Meanwhile when molding sand enters on the inside of protection ring, molding sand can fall on the inside of protection ring along the arc inner wall of protection ring Out;In order to ensure the air-flow of spray head blowout can blow to the casting mold mobile in inner wall of rotary drum, the arc of protection ring is minor arc, convenient Air-flow is blown in roller, and spray head, between protection ring and air guide ring, the air-flow sprayed from spray head passes through the guiding of air guide ring Effect is flowed towards inner wall of rotary drum.
2, with casting mold, ceaselessly rolling is advanced in roller, and the molding sand of casting periphery, which is not cut off, to be fallen, when casting mold moves to When discharge end, the volume of entire casting mold is reduced with falling for molding sand, and molding sand is loosely many, no longer needs to cast at this time When type picture just enters roller from feed end, need biggish impact force that could complete knockout, at this time in order to protect casting will not be because It hits and damages, roller discharge end internal diameter is less than feed end internal diameter, to reduce the amplitude that casting mold is fallen in discharge end side, reduces Impact force protects casting will not damage to a certain extent;Simultaneously in order to enable impact force with molding sand the gradual change of falling Process, inner wall of rotary drum are cone in discharge end side.
