Abstract
The invention discloses a sand mold machining device for a hollow casting, and relates to the technical field of casting machining. The sand mold machining device comprises a sand box, an upper mold, a lower mold, a first air cylinder controlling the upper mold to ascend and descend, a second air cylinder controlling the lower mold to be opened and closed, a sand mold conveying plate, a third air cylinder controlling the sand mold conveying plate to rotate and a fourth air cylinder controlling the sand mold conveying plate to stretch and retract. A sand feeding pipe is vertically arranged in the center inside the sand box. A compressed air inlet is formed in the side wall of the sand box. The top of the sand box is provided with a sand inlet communicated with the sand inlet pipe. The first air cylinder is fixed to the portion above the sand box through a door-shaped support, the upper mold is controlled to ascend and descend by means of a supporting rod and a connecting plate, a sand mold cavity is formed after the upper mold and the lower mold are closed, and the fourth air cylinder is fixed to a guide rod of the third air cylinder. Automatic machining of the sand mold can be achieved, the compactness of the sand mold can be improved, the integrity of the sand mold structure can be ensured, and the conveying efficiency can be improved.
Description
Technical field：
The present invention relates to Mechanical processing of casting technical field, and in particular to a kind of sand mold processing unit (plant) of hollow casting.
Background technology：
Sand casting, is the casting method that foundry goods is produced in sand mold.Steel, iron and most of non-ferrous alloy castings all can use
Sand mould casting method is obtained.Because the Modeling Material used by sand casting is cheap and easy to get, Casting mold manufacturing is easy, the single-piece to foundry goods
Production, produce by batch and produce in a large number and adapt to, for a long time, the basic technology always in Foundry Production.In sand mold casting
In making technique, it is necessary first to manufacture molding sand mould, the dimensional accuracy of molding sand mould will directly affect the quality of foundry goods.Traditional handicraft
It is that first metal die is put into sandbox, then molding sand is added in sandbox, then sand compaction is made by manual compression molding sand.This
The mode of kind haves the shortcomings that big labour's input amount, inefficiency and sand compaction control are uneven, is not suitable for high-volume
Production.
The content of the invention：
The technical problem to be solved be provide a kind of sand compaction it is high, automation hollow casting sand
Type processing unit (plant).
The technical problem to be solved is realized using following technical scheme：
A kind of sand mold processing unit (plant) of hollow casting, including sandbox, upper die and lower die, the first cylinder of mould lifting in control,
3rd cylinder and control sand mold of second cylinder, sand mold transfer plate and the transfer plate rotation of control sand mold of the lower mould opening and closing of control is passed
The 4th cylinder for sending plate flexible, the sandbox inside center is vertically provided with sand-feeding tube, and sandbox side wall is provided with compressed air inlet,
Sandbox top is provided with the sand inlet communicated with sand-feeding tube, and first cylinder is fixed on sandbox top, then profit by door shaped stent
With pole and the upper mould lifting of connecting plate control, sand mold chamber is formed after the upper mould and lower mould closure, the 4th cylinder is fixed on
On the guide rod of the 3rd cylinder.
3rd cylinder is rotary cylinder.
The sand inlet is in up-narrow and down-wide truncated cone-shaped structure.
The invention has the beneficial effects as follows：The present invention realizes the closure of sand mold mould by the first cylinder and the second cylinder, then
Molding sand is entered into sand mold chamber by sand-feeding tube using compressed air, the automation processing of sand mold is realized, the degree of packing of sand mold is improved,
And be removed from the molds in the molding sand for processing by the 3rd cylinder, the 4th cylinder and sand mold transfer plate, it is ensured that sand mould structure
Complete and raising transmission efficiency.

Specific embodiment：
In order that technological means, creation characteristic, reached purpose and effect that the present invention is realized are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
As shown in figure 1, mould liter on a kind of sand mold processing unit (plant) of hollow casting, including sandbox 1, upper mould 2, lower mould 3, control
The 3rd of first cylinder 4 of drop, the second cylinder 5 of the lower mould opening and closing of control, sand mold transfer plate 6 and the transfer plate rotation of control sand mold
The 4th flexible cylinder 8 of cylinder 7 and control sand mold transfer plate, sandbox inside center is vertically provided with sand-feeding tube 9, sets on the wall of sandbox side
There is compressed air inlet 10, sandbox top is provided with the sand inlet 11 communicated with sand-feeding tube, and the first cylinder is solid by door shaped stent 12
Sandbox top is scheduled on, pole 13 and the upper mould lifting of the control of connecting plate 14 is recycled, after upper mould and lower mould closure sand mold chamber 15 is formed,
4th cylinder is fixed on the guide rod 16 of the 3rd cylinder, and the 3rd cylinder is rotary cylinder, and sand inlet is in up-narrow and down-wide truncated cone-shaped
Structure.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification this
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes
Change and improvement is both fallen within scope of the claimed invention.The claimed scope of the invention by appending claims and its
Equivalent thereof.
