Description

A kind of core making machine blasting unit installs structure
Technical field
The present invention relates to the parts of a kind of metal casting machine, it is specifically related to a kind of blasting unit to core making machine and positions and the device of fast assembling-disassembling.
Background technology
In casting technique, preparing the fixed of core and penetrate in a core making machine, head is fixed on directly over core box with penetrating to penetrate chamber. In common structure, the chamber of penetrating of cylinder shape is fixed on top rack, penetrate head to be fixed on and penetrate the lower end in chamber, penetrate for penetrating sand plate bottom head, usually, blasting unit is adopted to realize core sand and the isolation of air inlet and exhaust-duct, blasting unit is cylindrical structural, is installed on and penetrates in chamber, and through adding, sand butterfly valve connects sand hopper at blasting unit top, blasting unit and penetrate between the wall of chamber and general to adopt circumference seal form, bottom by penetrating sand plate fix through blasting unit support bar. During installation, relying on artificial upwards insertion by blasting unit to penetrate chamber, the sealed strip sealed by circumference and the frictional force penetrated between the wall of chamber make blasting unit not drop, and then install and penetrate sand plate, utilize the installation locking force penetrating sand plate to compress through blasting unit support bar and support blasting unit, complete blasting unit and install. During dismounting, after first penetrating the dismounting of sand plate, manually blasting unit is hauled out and penetrate chamber, complete blasting unit dismounting.
In the industrial production, usually, when per tour is started shooting, blasting unit is in place, by blasting unit dismounting cleaning during shutdown.
In technique scheme, because needing artificial lift to install, general blasting unit material adopts lightweight material, such as special nylon. Owing to blasting unit adopts circumference sealing, sealing position circular degree is required high. Usually, after blasting unit uses for some time, producing distortion penetrating, cause blasting unit circumference sealing deleterious under sand air flue reactive force, artificial insertion is installed and dismounting difficulty. Simultaneously, it may also be useful to the time is more long, circumferential deformation is more serious, and sealing effect even can be made to lose efficacy, and after causing admission passage, exhaust line to enter sand, penetrates sand component damage.
Consequently, it is desirable to the installation structure of blasting unit improved, so that the sealing of blasting unit is more reliable, facilitate the handling of blasting unit simultaneously.

Above, described locating mechanism utilizes tumbler pin that the top flange of blasting unit is spacing, more upwards oppresses blasting unit support bar by penetrating sand plate, blasting unit is pressed in and penetrates in chamber. When installing blasting unit, manually upwards being inserted by blasting unit and penetrate chamber, press controlling organization, make driving mechanism action, tumbler pin inward after putting in place, blasting unit is hung on tumbler pin. Install again and penetrate sand plate, rely on blasting unit lower support bar to support sealing, complete blasting unit and install. During dismounting blasting unit, sand plate is penetrated in first dismounting, then makes driving mechanism action by controlling organization, and tumbler pin is outwards retracted in orienting sleeve, and blasting unit unloads.
In technique scheme, described driving mechanism can be various ways, such as pneumatic, hydraulic pressure, magnetic control, electronic etc., the corresponding control device that described controlling organization is then and driving mechanism coordinates. Preferred technical scheme, described driving mechanism is cylinder, and described controlling organization is Pneumatic valve. This Pneumatic valve can be hand-operated pneumatic control valve, and described hand-operated pneumatic control valve is fixedly connected on through mounting plate to be penetrated on head. Pressing hand-operated pneumatic control valve, drive cylinder locking, blasting unit is hung on tumbler pin, unclamps hand-operated pneumatic control valve, drives cylinder to unclamp, and blasting unit unloads.
In technique scheme, described first sealed structure is, at the upper surface of the top flange of blasting unit, offer the first annular seal groove, being embedded with the first annular sealing strip in described first annular seal groove, blasting unit top flange forms flat seal between internal surface at the bottom of the first annular sealing strip and permanent seat cylinder.
Described 2nd sealed structure is, at the upper surface of the bottom flange of blasting unit, offered second ring sealing groove, in described second ring sealing groove, be embedded with second ring sealed strip, blasting unit bottom flange through second ring sealed strip and penetrate head top board between form flat seal.
Preferred technical scheme, is provided with two blasting unit support bars, and the bottom flange circumference of the described relative blasting unit of blasting unit support bar is uniformly distributed.
In technique scheme, described blasting unit support bar is fixedly connected on bottom blasting unit on flange, with core making machine penetrate sand plate compression fit.
Or, what described blasting unit support bar was fixedly connected on core making machine penetrates on sand plate, with flange compression fit bottom blasting unit.
Preferred technical scheme, is provided with locating mechanism described in three groups, and described locating mechanism is uniformly distributed along the barrel circumference of permanent seat.
Further technical scheme, the lower end of described blasting unit is fixedly connected with pull bar.
Owing to technique scheme is used, the present invention compared with prior art has following advantage:
1. the present invention is by arranging flange, utilizes the end face of blasting unit to seal, and forms flat seal form, compared with circumference of the prior art sealing, it is possible to handling difficulty problem after effectively avoiding blasting unit to be out of shape, seals more reliable simultaneously.
2. the present invention is by arranging permanent seat and locating mechanism, tumbler pin is utilized to carry out blasting unit hanging location, then sand plate is penetrated in installation, can not by the constraint of circumference sealing-ring when blasting unit passes in and out, easy to loading and unloading, and sealed structure can not produce detrimentally affect by handling process.
