Technical field
The invention belongs to Shell Casting Technology fields, and in particular to a kind of shell mould mould closer and side by screw fastening
Method.
Background technique
Shell moulded casting is a kind of sand mould casting method of precision, it is sand in coating phenolic resin to be heating and curing or cold core
Box sand aerating solidification, on metal form formed certain thickness (general 6-12mm) shell shell mould, reach required for intensity and
Rigidity.Sand core is placed in shell mould, upper and lower two panels shell mould bolt or clamp assembly mould assembly constitute casting mold.
Automobile turbocharger turbine case casting structure is complex, is in single, double runner three-dimension curved surface streamline construction, weight
Several kilograms to tens kilograms, the main wall thickness 4-5mm of volute, and wall thickness became uneven, thermal center lug is more, cast(ing) surface and inherent matter
Amount requires height, and dimensional accuracy is high, is not allow for any casting flaw.So proper using shell mold process.Other works
The productions such as journey machinery such as pump valve, hydraulic part, crankshaft batch is larger, dimension precision requirement is high, the thin and complex-shaped various conjunctions of wall
Golden casting is also suitable for shell moulded casting production method.
In shell moulded casting production process, general one mould of shell arrangement 2 or one-mold multiple-member, shell mould size and mould assembling weight
To be relatively large, also have small-sized.General small-sized, upper and lower two panels shell mould is by 2 bolts, nut and gasket mould assembling fastening
It can；And it is relatively large, upper and lower two panels shell mould passes through 4 or more bolts, nut and gasket mould assembling fastening, cumbersome, production
It is automatic to be not suitable for mass industrialization, robot for low efficiency, and bolt damage easy to wear when peeling, high production cost
Metaplasia produces, it is therefore desirable to improve to existing shell mould mould assembling clamp device.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of shell moulds fastened by dedicated tapping screw
Mould closer, it is simple, reliable, convenient, the production time is saved, production cost is reduced, it is automatic to meet mass industrialization, robot
Metaplasia producing line needs.
In order to solve the above technical problems, the technical solution of the present invention is as follows:
The shell mould mould closer fastened by screw, including cope shell, drag sheel and dedicated tapping screw, it is described upper and lower
Shell mould is equipped at least two fastening protrusion, and the corresponding through-hole of upper drag sheel mould assembling, drag sheel parting are equipped on fastening protrusion
For face peripheral edge after gluing, upper drag sheel positions mould assembling, the dedicated tapping screw screwing device, including specific purpose tool and dedicated
Tapping screw, dedicated tapping screw are screwed in each through-hole by specific purpose tool, and shell mould mould assembling fastening process is rapidly completed.
As advanced optimizing for the technical program, the upper and lower shell mould fastening protrusion and through-hole thereon are corresponding, and
The diameter of through-hole is less than the outer diameter of dedicated tapping screw.
As advanced optimizing for the technical program, the dedicated tapping screw is that the self tapping of specific use designs spiral shell
Nail, using Type B A angular thread.
4, a kind of shell mould mould assembling method fastened by screw, comprising the following steps:
1) using resin-coated sand shell mould machine or cold-box core making machine production cope shell and drag sheel, using overlay film sand shell core machine system
Make inner cavity sand core；
2) spraying of upper drag sheel type chamber is coated, and dried；Inner cavity sand core dip-coating is simultaneously dried；
3) mould assembling is positioned along joint sealing glue, upper drag sheel is uniformly beaten in drag sheel die joint peripheral edge；
4) in the corresponding through-hole of upper drag sheel, dedicated tapping screw is screwed in by it using specific purpose tool from top to bottom
In, then install sprue cup etc. additional on cope shell, complete shell mould mould assembling fastening process.
The beneficial effects of the present invention are:
This by screw fasten shell mould mould closer and method, the corresponding fastening protrusion being equipped with by upper drag sheel
And dedicated tapping screw is screwed into through-hole after upper drag sheel gluing positioning mould assembling using specific purpose tool by through-hole from top to bottom,
Complete shell mould mould assembling fastening process.The troublesome operation process of existing bolt and nut fastening mould assembling is eliminated, it is simple, reliable, convenient,
The production time has been saved, production cost is reduced, has met mass industrialization, robot automation's production line needs.
Detailed description of the invention
A specific embodiment of the invention is described in further detail with reference to the accompanying drawing.
Fig. 1 is the cross-sectional view of the shell mould mould closer fastened by screw.
Fig. 2 is the top view of Fig. 1.
Wherein, 1- cope shell, 11- fastening protrusion, 12- through-hole, 2- drag sheel, 21- fastening protrusion, 22- through-hole, 3- are dedicated
Tapping screw, 4- sand core.
Specific embodiment
Present invention is further described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1 and Figure 2, a kind of shell mould mould closer fastened by screw and method, including cope shell (1), lower casing
Type (2) and dedicated tapping screw (3), cope shell (1) and drag sheel (2) periphery are equipped with 8 corresponding fastening protrusions (11)
(21), fastening protrusion (11) (21) is equipped with 8 corresponding through-holes (12) (22), and drag sheel (2) die joint peripheral edge edge is beaten
After positioning mould assembling with cope shell (1) after glue, in 8 upper lower through-hole (12) (22) on fastening protrusion (11) (21), using special
Dedicated tapping screw (3) is screwed in wherein from top to bottom with tool, shell mould fastening mould assembling process is rapidly completed.
Since sand mold shell mould is relatively wooden or metal material is more crisp, intensity is lower, so dedicated tapping screw must be used
(3), the drilling on shell mould fastening protrusion in advance is needed, and aperture is less than the outer diameter of screw, screw pitch is greater than general screw, is guaranteeing
Under the premise of boss is not by squeeze crack, the fastening mould assembling power of screw is improved.
Drag sheel, inner cavity sand core, dedicated tapping screw, specific purpose tool and sprue cup etc. in preparation.
On mass industrialization, robot automation's production line, first the automatic snatch of robot by cope shell (1), under
Shell mould (2) type chamber sprays respectively to be coated, and enters through the drying of formula drying oven；Each chamber sand is manually placed into drag sheel (2)
Core (4), Robot drag sheel (2) peripheral edge reposition mould assembling, then on each fastening protrusion (11,21) along joint sealing glue is played
Through-hole (12,22) in manually dedicated tapping screw (3) is screwed in wherein, then on cope shell from top to bottom using specific purpose tool
It installs sprue cup etc. additional, the mould assembling fastening process of shell mould is rapidly completed, is transported to designated position through automatic production line, robot passes through
Two sides snatch to casting station.
The above content be only to structure of the invention example and explanation, for affiliated those skilled in the art,
Under the premise of not departing from the invention design, various modifications and improvements can be made, these belong to protection of the invention
Range.
