Description
Technical field
The utility model relates to automatic Casting Equipment field, the hollow template of especially a kind of automatic moulding machine.
Background technique
Sand casting is one of most widely used production method in casting industry, suitable for steel, iron and a variety of has coloured gold
Belong to.When horizontal parting moulding machine is applied to the manufacture of clay sand mold, have many advantages, such as that high production efficiency, quality are stablized.Its principle is
Clay-bonded sand is blown into the upper and lower sandbox equipped with mold using compressed air, using external force compression moulding, then takes out mold,
Upper and lower sand mold is accurately positioned to merge and forms complete sand mold.
The falsework of horizontal parting moulding machine is single-layer double-side template, during clay-bonded sand is blown into sandbox, because of air
It is big to flow obstructed or mould high and low fall, blocks when penetrating sand, causes sand mold filling not enough to enrich, part occurs
Sand is lacked, is easy to generate incrustation, burr at the parting line of cast article, influences product quality.
Utility model content
The purpose of the utility model is to overcome the above technological deficiency, propose that a kind of improvement penetrates sand Airflow and moves situation,
The hollow template of automatic moulding machine big in mould high and low fall, that sand shot has the place blocked to be equipped with exhaust apparatus.
The utility model is adopted the technical scheme that by its technical purpose of realization: a kind of automatic moulding machine hollow mould
Plate, including a moulding mould and a falsework, it is characterised in that: the moulding mould is arranged in the falsework, institute
The upper plate, center and lower plate that falsework includes one group of movable connection are stated, is surrounded in one between the upper plate, center and lower plate
Cavity body between the upper plate and center and between lower plate and center, is additionally provided with pattern plate bolster seam allowance；The upper plate with
In lower plate, the moulding mould periphery be equipped with venthole；
Be additionally provided with through-hole in the center side, be connected with air inlet pipe on the outside of the through-hole, the through-hole connection it is described into
Tracheae and the hollow cavity.
Preferably, the frame section of the center is step, so that reserving the hollow of 10-15MM between upper plate and lower plate
Layer.
Preferably, it is connected by screw bolts between the upper plate, center and lower plate.
Preferably, the venthole on the upper plate and lower plate corresponds.
The beneficial effects of the utility model are: the falsework of original horizontal parting moulding machine is made into Double-layer Opening
Design, is changed to two-sided single side for original single-layer double-side template, reserves the hollow of 10-15MM between two layers of template in installation process
Layer, then big in mould high and low fall, sand shot has the place installation exhaust apparatus blocked, is realized with this in air-flow sand shot
Airflow direction is guided, solves the problems, such as scarce husky, the raising sand mold Forming Quality of clay sand in the initial state, raising casting
Product quality.
Detailed description of the invention
Fig. 1 is the utility model overall top view.
Fig. 2 is air inlet pipe sectional view.
Fig. 3 is through hole section figure.
Fig. 4 is the utility model overall perspective view.
In the figure, it is marked as 1, moulding mould；2, falsework；20, hollow cavity；21, upper plate；22, center；23 lower plates；
24, pattern plate bolster seam allowance；25, venthole；3, through-hole；4, air inlet pipe.
Specific embodiment
Embodiment is described further the utility model with reference to the accompanying drawing.
Embodiment one
It is as shown in Figs 1-4: a kind of hollow template of automatic moulding machine, including a moulding mould 1 and a falsework 2, institute
It states moulding mould 1 to be arranged in the falsework 2, the falsework 2 includes upper plate 21, the center of one group of movable connection
22 and lower plate 23, the frame section of the center 22 is step, using high-strength between the upper plate 21, center 22 and lower plate 23
Degree is bolted, so that a hollow cavity 20 is surrounded between the upper plate 21, center 22 and lower plate 23, in the upper plate 21 in
Between frame 22 and between lower plate 23 and center 22, it is additionally provided with pattern plate bolster seam allowance 24；On the upper plate 21 and lower plate 23, institute
It states 1 periphery of moulding mould and is equipped with venthole 25；
It is additionally provided with through-hole 3 in 22 side of center, air inlet pipe 4 is connected on the outside of the through-hole 3, the through-hole 3 is connected to
The air inlet pipe 4 and the hollow cavity 20, and the venthole 25 in the upper plate 21 and lower plate 23 corresponds.
The working principle and the course of work of the utility model are as follows:
Upper plate 21, center 22 and lower plate 23 are connected firmly by present apparatus high-strength bolt；Using external vacuum pump, pass through
Pipeline connects air inlet pipe 4, and via through holes 3 aspirate hollow cavity 20, so that forming certain negative pressure in hollow cavity 20, passes through ventilation
Hole 25, so that 1 surrounding of moulding mould generates certain negative pressure, the sand when automatic moulding machine penetrates sand molding, around moulding mould 1
The degree of packing of son will significantly improve, and greatly reduce caused by automatic moulding machine blows unevenly blast around mold and lack husky casting
Make the defect of rear more iron, the overlap for reducing casting mould parting line is too many, too big etc. casting flaws, can make mold by this device
Surrounding close-over surface hardness reaches 80 ~ 90g/mm2, substantially improves the effect of machine molding.
The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of variation.But it is all without departing from the content of the technical scheme of the utility model, the technology according to the utility model is real
Matter any simple modification, equivalent variations and remodeling to the above embodiments, still fall within the guarantor of technical solutions of the utility model
Protect range.
