Abstract
The present invention is a kind of Multi-point floating pressing device of shell mould bonding contact.After shell mould point two panels is made, operated through lower core etc., finally by glue on shell mould die joint by two panels shell mould mould assembly, when the larger die joint of shell mould easily deforms out-of-flatness, die joint is typically compressed using compressing method, but shell mould is single face-formed, and back is rough, stress is extremely uneven everywhere for die joint during compression, and gap is also inconsistent.The present apparatus is pressed in opposite directions with position in shell mould die joint back Multi-point floating, each depression bar respectively the liquid plasticses in by same floating case in depression bar end top pressure, energy adjust automatically extension elongation, and pressure is consistent, the big portion of die joint of shell mould is compressed by uniform pressure, make the contact of shell mould die joint uniform seamless, casting appearance and size error is controlled.
Description
Technical field
The special purpose device that die joint bonding compresses in the manufacture of foundary industry shell mould.
Background technology
The gas heating autoclino of German bold and unconstrained freeze-frame company import, it is mounted split pattern shaping, template area is up to 700
× 600, the increasingly automated equipment of shell mould thickness is controlled according to the precoated sand heat time.Due to being single face-formed, sand grains is not
It is heating and curing by mould molding, is that the shell mould back side just turns into precoated sand and dissipates heap by heat cure by heat cure with Gas Infrared baking
Natural completed state and it is rough.When two panels shell mould die joint split, die joint easily cooling strain, and make die joint it
Between produce gap, after being so bonded with glue, in use, molten iron will ooze out from die joint gap, in cast(ing) surface shape
Into irregular overlap, while it can also make casting profile variation, the scale error increase of casting.
In pouring molten iron, although pressurizeing iron in shell mould, foundary weight crosses that catheresis is little, and foundary weight can damage by pressure as overweight
Shell mould, so the die joint closeness of contact of shell mould mould assembly is a common problem.
The content of the invention
The purpose of the present invention is a kind of Multi-point floating pressing device of shell mould die joint bonding contact.For shell mould die joint
It is rough outside rectangular flange side, with die joint flange shape identical more bar floating casees up and down, the opposite working face of casing
On be provided with it is double intersect multiple strut kongs, depression bar is averagely often arranged installs one every 30mm, the full liquid plasticses of storage in casing, by
The strict density of adjustment lid control liquid plasticses, when the shell mould of bonding is lain in pressing device, casing divides upper and lower surface pressure
During to shell mould, the depression bar on casing working face just pushes down shell mould die joint flange, each depression bar in the end face of box house,
During compression, while extruded by liquid plasticses in casing, extension elongation can be automatically adjusted, and keep pressure consistent, casing is by rising
Sending down abnormally ascending cylinder, which drives, to be separated and closes, and is applied pressure, shell mould die joint each point is extruded by uniform pressure, is promoted point
Type face is in close contact.
The technical scheme is that more bar floating casees under being installed on base, working face is provided with strut kong on casing.Pressure
Depression bar is installed in rod aperture, stores full liquid plasticses, bottom installation and adjustment lid in casing, base both sides are fixed with guide pillar, on guide pillar
Portion's fixed cross beam, crossbeam middle part installation lift cylinder, the upper more bar floating casees of cylinder lower piston bar connection, there is fixation casing both sides
Guide pin bushing, guide pin bushing can slide up and down on guide pillar, and working face is provided with strut kong, more bars under strut kong neutralizes to upper more bar floating casees down
Floating case installs depression bar with position in opposite directions, and full liquid plasticses, upper bottom portion installation and adjustment lid, upper more bar floating case both sides are stored in casing
Equipped with conveying support plate, shell mould can be placed on supporting plate.
The distinguishing feature of the present invention be when pressing device compresses to shell mould, due to depression bar in casing simultaneously by
To the extruding of liquid plasticses, the height of depression bar can automatically adjust, and just make the hackly surface each point at the die joint back side of shell mould
It can be extruded simultaneously by uniform pressure, the whole die joint of shell mould is all compressed by constant pressure, not at omission, more will not
Bad local shell mould is squeezed, effectively improves the mould assembly precision of shell mould.
Described liquid plasticses add plasticizer by epoxy resin and curing agent is made.

Embodiment
More bar floating casees 10 under being installed on base 1, more bar floating casees 10 are provided with strut kong, strut kong upward on working face
It is middle that depression bar 9 is installed, full liquid plasticses 11 are stored in casing, bottom half mounting and adjusting lid 7, the both sides of base 1 are fixed with guide pillar
2, the top fixed cross beam 3 of guide pillar 2, the middle part of crossbeam 3 installation lift cylinder 4, the upper more bar floating casees of the lower piston of lift cylinder 4 connection
5, guide pin bushing 6 is fixed in the casing both sides of upper more bar floating casees 5, and guide pin bushing 6 can be slided freely up and down on guide pillar 2, upper more bar floating casees 5
Strut kong is provided with working face directed downwardly, more bar floating casees install depression bar 9 with position in opposite directions under strut kong neutralizes, and are stored in casing full
Liquid plasticses 11, casing top mounting and adjusting lid 7, upper more both sides of bar floating case 5 are equipped with conveying support plate 8, can put on conveying support plate 8
Put shell mould 12.
