Description
Technical field
The utility model belongs to Shell Casting Technology field, and in particular to a kind of shell mould mould assembling dress fastened by screw
It sets.
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 are measured, thermal center lug is more, cast(ing) surface and interior
In quality requirement height, dimensional accuracy is high, is not allow for any casting flaw.So proper using shell mold process.Its
The productions such as its engineering machinery such as pump valve, hydraulic part, crankshaft batch is larger, dimension precision requirement is high, wall is thin and complex-shaped each
Kind alloy-steel 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
It is relatively large for measuring, and is also had small-sized.General small-sized, upper and lower two panels shell mould is tight by 2 bolts, nut and gasket mould assembling
Gu；And it is relatively large, upper and lower two panels shell mould is fastened by 4 or more bolts, nut and gasket mould assembling, and it is cumbersome,
Production efficiency is low, and bolt damage easy to wear when peeling, high production cost, is not suitable for mass industrialization, robot
Automated production, it is therefore desirable to which existing shell mould mould assembling clamp device is improved.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide one kind and are fastened by dedicated tapping screw
Shell mould mould closer, it is simple, reliable, convenient, save the production time, reduce production cost, meet mass industrialization, machine
Device people's automatic production line needs.
In order to solve the above technical problems, the technical solution of the utility model are as follows:
The shell mould mould closer fastened by screw, including cope shell, drag sheel and dedicated tapping screw, it is described on
Drag sheel is equipped at least two fastening protrusion, and the corresponding through-hole of upper drag sheel mould assembling, drag sheel are equipped on fastening protrusion
For die joint peripheral edge after gluing, upper drag sheel positions mould assembling, the dedicated tapping screw screwing device, including specific purpose tool
With dedicated tapping screw, dedicated tapping screw is screwed in each through-hole by specific purpose tool, and shell mould mould assembling fastening is rapidly completed
Process.
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, through-hole diameter is the 0.6-0.8 of dedicated tapping screw outer diameter
Times.
As advanced optimizing for the technical program, the dedicated tapping screw is the special designs spiral shell of specific use
Nail, using Type B A angular thread.
The beneficial effects of the utility model are:
The shell mould mould closer fastened by screw, the corresponding fastening protrusion being equipped with by upper drag sheel and logical
Dedicated tapping screw is quickly screwed into through-hole using specific purpose tool after upper drag sheel gluing positioning mould assembling, completes shell by hole
Type mould assembling fastening process.The troublesome operation process of existing bolt and nut fastening mould assembling is eliminated, it is simple, reliable, convenient, it saves
Production time, production cost is reduced, mass industrialization, robot automation's production line needs are met.
Detailed description of the invention
Specific embodiment of the present utility model 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 special
With tapping screw, 4- sand core.
Specific embodiment
The utility model is described in further 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, including cope shell (1), drag sheel (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 is after gluing
After positioning mould assembling with cope shell (1), in 8 upper lower through-hole (12) (22) on fastening protrusion (11) (21), use is dedicated
Tool screws in dedicated tapping screw (3) wherein from top to bottom, and 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 protecting
Under the premise of boss is demonstrate,proved 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) are screwed in wherein using specific purpose tool, then install additional and pour on cope shell
Cup etc., is rapidly completed the mould assembling fastening process of shell mould, is transported to designated position through automatic production line, robot passes through two sides
Snatch to casting station.
The above content is only to the utility model structure example and explanation, and affiliated those skilled in the art comes
It says, without departing from the concept of the present invention, various modifications and improvements can be made, these belong to this
The protection scope of utility model.
