Abstract
The invention discloses a camshaft housing precise casting method and special full-set tooling, comprising a housing precise casting special full-set tooling, and a camshaft housing casting mold, wherein a pouring system is fixedly arranged on a template of an iron trolley, a frame is sheathed on a seam allowance of the template, resin sand is filled in the frame of the trolley, the upper surface of the resin sand is scraped by a scraper, the trolley with the template is pushed in a carriage type resistance furnace along a track for heating within certain time so as to cure and form resin sand, and then is pulled out of the carriage resistance furnace along the track, a molding sand ejector rod of the trolley with the template and an adjusting screw bolt of a demolding mechanism are aligned and contacted with each other, a handle of a crank-link mechanism of the demolding mechanism is rotated to lift a lifting plate of a lifting mechanism under the action of an eccentric wheel, and the adjusting screw bolt fixedly arranged on the lifting plate drives the molding sand ejector rod for lifting, so that the cured housing and the mold are separated, and the cured housing is taken down after the frame is taken down and stored in a housing storage region. In the invention, a special full-set tooling applicable to precise casting of small-batch and various camshaft housings is designed and manufactured.
Description
Technical field
The present invention relates to precision casting of camshaft housing moulds blank special tooling manufacturing technology, specifically belong to a kind of precision casting of camshaft housing moulds method and Special complete tool.
Background technology
The precision casting of camshaft housing moulds blank has the advantages such as dimensionally stable, allowance are little, dense structure, and being widely used in material is the Engine Cam axis blank manufacturing of foundry goods.Foundry need be equipped with hot box shoot core machine and produce shell mould during batch production, and the shell mould casting production line is used for shell mould mould assembling, the casting of blank, and the disposable input of factory is large and be not suitable for the blank production of the many kinds of small lot.
Content of the present invention
The purpose of this invention is to provide a kind of precision casting of camshaft housing moulds method and Special complete tool, design, produce the Special complete tool for precision casting of camshaft housing moulds that is applicable to the many kinds of small lot.
The technical solution used in the present invention is as follows:
A kind of precision casting of camshaft housing moulds method and Special complete tool; comprise the shell mould Special complete tool for precision casting; the camshaft casing casting die; running gate system is installed on the template of the little car bottom plate of swage; the type frame is placed on the seam of template; fill with resin sand in the described dolly type frame; strike off upper plane with scraper plate; the template dolly pushed in the van-type resistance furnace along track heat a period of time; make the resin sand curing molding; again the template dolly is pulled out the van-type resistance furnace along track; molding sand push rod on the template dolly is alignd with the adjusting double-screw bolt of mould emptier, rotate the handle of the toggle of mould emptier, the lifter plate of elevating mechanism is risen; driving the molding sand push rod rises; the shell mould of having solidified is separated with mould, the shell mould that is cured is taken off after taking off the type frame, be placed on the shell mould storage area and deposit.
Described this frock is fixed with respectively mould emptier by both sides, workbench upper surface; mould emptier comprises the mould emptier axle; eccentric wheel; mould emptier axle supporting base; fore-set; the fore-set supporting base; lifter plate; the mould emptier axle sleeve is loaded on the mould emptier axle supporting base; be fixed with eccentric wheel on the mould emptier axle; one end suit mould emptier axle supporting base; the other end is fixed with handle; left; right eccentric wheel connects respectively left by the mould emptier axle; right handles; left; connected by connecting rod between the right handles; lifter plate is installed on the fore-set; be fixed with the adjusting double-screw bolt on the lifter plate; fore-set is set on the fore-set supporting base; fore-set is provided with roller, and roller contacts with eccentric wheel, when clockwise rotating handle; be installed in the fore-set on the eccentric wheel jack-up lifter plate on the mould emptier axle and regulate double-screw bolt; regulate double-screw bolt and align with molding sand push rod on the swage dolly and contact, the swage car wheel is located on the guide rail, and described mould emptier axle supporting base and fore-set supporting base are packed on the workbench.
Described shell mould Special complete tool for precision casting left and right sides template is placed upper and lower model simultaneously, the simultaneously moulding of upper and lower shell mould.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention designs the precision casting of camshaft housing moulds frock and need not to be equipped with hot box shoot core machine and produce shell mould, the dedicated pouring production line be need not lay and shell mould mould assembling, the casting of shell mould hot investment casting finished, greatly reduced the disposable input cost of foundry, the little car bottom plate of template and template, mould and template are all located with the screw connecting pin, be convenient for changing template and mould, the Foundry Production that can be used for many kinds of small lot precision casting of camshaft housing moulds blank has reduced cam shaft blank casting cost.
