Detailed description of the invention
It is described in further detail below in conjunction with the accompanying drawings and by way of example to the present invention.
The preparation method of a kind of large-scale vertical-parting self-curing mo(u)ld, chooses foundry goods cross section as vertical point according to foundry goods profile
Profile 3, typically chooses the maximum cross-section of foundry goods as vertical-parting face 3, easy typing, casting mold is divided into left and right two parts, root
The mould 18 with positioner is designed, by mould 18 and sandbox 13, to left and right according to foundry goods parting surface structure
Sand mold carries out flash mould, and the corresponding sand mold of mould positioner completing to leave on rear left and right sand mold by moulding fills
Join detent mechanism, the left and right sand mold of molding is carried out the casting mold cavity needed for mould assembling fastening is formed.Described herein with location dress
The positioner on mould 18 put can be alignment pin or hole, location, it is possible to as in figure 2 it is shown, according to the spy of foundry goods itself
Different structure carries out location i.e. core print 4 and positions.Owing to being affected by positioner on mould 18 when casting sand type, sand mold
Define the sand mold assembling detent mechanism adapted with mould positioner, it is thus possible to carry out left and right sand mold accurately
Assembling.
Mould forming surface is provided with anti-runout structure 8, and when preventing from casting, aluminum liquid goes out to overflow from die joint, runs away
Problem.Its principle be metal in flow process due to the appearance of knuckle, flow resistance increases, it is to avoid liquid metal enter one
Step flowing.Anti-runout structure 8 can be lenticular anti-runout structure 12 or beveled structure.
Anti-runout concaveconvex structure 12 width is 10mm～50mm, uses matched in clearance, and fit clearance is 0.5mm～1mm.
Anti-runout beveled structure knuckle height is 10mm～20mm.
Some baroque sand casting also need under casing and top box, and after the combination of left and right sand mold, upper and lower surface is due to also
Need to assembling with top box and under casing, so also requiring that parallel to each other, and keeping vertical with vertical-parting face.Therefore at mould
Arranging side plate 5, location-plate 6, baffle plate 7 on 18, side plate 5 is positioned at the symmetrical two ends of baffle plate 7, and location-plate 6 is positioned at baffle plate 7 additionally
Two symmetrical ends, the effect of location-plate 6 is contemplated to ensure that side plate 5 keeps vertically and horizontally.Location-plate 6, side plate 5 are equal with sandbox 13
Not contacting, side plate 5 relies on location-plate 6 and baffle plate 7 to position (positioning boss of side plate positions), side plate with the locating slot of baffle plate
5 with sandbox 13 end clearance be 0.5mm～1mm.Wearing plate 9 is arranged on the corner of mould 18 die joint, and in location
Plate 6 and the inner of side plate 5, and exceed baffle plate 7 forming surface 0.5mm～1mm, wearing plate 9 is used for lifting sandbox 13, makes sand face slightly
Higher than sandbox face, during the assembling of left and right casting mold, sand face is relied on to coordinate.
After the left and right casting mold made processes, utilizing assembling structure in casting mold location to be accurately positioned, sandbox is provided with casting mold assembling
The guider 17 assembling when casting mold combines guides, and it can position with baffle plate 7 when moulding, it is achieved 13, sandbox
The accurate placement put.Sandbox is i.e. ready for cast with the mould assembling such as under casing, top box fastening.
The preparation method of sand mold Fig. 1 shown in is presented herein below, as follows:
Step 1 is according to the construction features of casting structure, it is first determined the vertical-parting face 3 of casting mold.Vertical-parting face 3 is general
Choose at casting mold maximum cross-section, it is ensured that being convenient in demoulding of left and right casting mold.Choose at external arc maximum cross-section as left and right casting mold
Die joint.For reducing the number of core, inner circle forming surface is arranged in left-hand mold, such as Fig. 1.
Step 2, according to die joint position determined by step 1, analyzes the construction features of casting mold, the dress of appropriate design casting mold
Join location structure such as core print 4 to position, as shown in Figure 2.
Step 3, according to casting mold structure determined by step 2, appropriate design mould 18, mould 18 by side plate 5,
Location-plate 6, baffle plate 7 (dead head apperance etc.), wearing plate 9 and other supplementary structure etc. form, as shown in Figure 3.Wearing plate 9
Being arranged on the corner of baffle plate 7, use screw to be fixed on baffle plate 7, upper surface exceeds die joint 0.5mm, such as Fig. 4 institute
Show.Anti-runout structure 8 is arranged on the die joint of baffle plate forming surface both sides, and this example uses lenticular structure, and Breadth Maximum is
20mm, uses matched in clearance, and fit clearance is 0.5mm, as shown in Figure 5.
Step 4, according to casting mold structure, mould 18, sandbox 13 determined by step 3, positions sandbox 13 and fastens
On baffle plate 7, side plate 5 utilizes location-plate 6 and baffle plate 7 position and fasten, now, deposit between side plate 5 and sandbox 13 end face
Gap at 0.5mm.Air-set mold resin sand consolidation is inserted toward sandbox 13, molding after self-hardening sand solidifies, concrete such as figure
Shown in 6-7.
Step 5, the left and right casting mold made by step 4 is processed after, utilize assembling structure in casting mold location to be accurately positioned, sandbox
13 are i.e. ready for cast with the mould assembling such as under casing, top box fastening.
The invention is not limited in above-mentioned embodiment, any those skilled in the art can do numerous modifications and variations,
Without departing from the spirit of the present invention, all in scope of the claimed of the present invention.
