Description
Technical field
The present invention relates to a kind of self-floating foundary weight, be specifically related to a kind of self-floating foundary weight for spacing core assembly pouring device.
Background technology
In the time that core group is carried out to core assembly pouring, except the mo(u)ld top half of core group can be subject to molten metal effect and on lift, the side type of core group can be subject to the effect of molten metal and swollen type too, so before cast, carry out the precautionary measures that prevent from lifting on mo(u)ld top half with the swollen type of side type.
Traditional mode is first to use C type clamp that sand mold clamping sides (or is used to sandbox, core group is put into), place again foundary weight in the above, then pour into a mould, after casting solidification, take off again foundary weight and C type clamp (or sandbox), existing technical method is all that the measure of the swollen type of prevention is divided into two procedures (above compression, clamp side), so more loaded down with trivial details in the time of operation, especially the operation of clamping sides time (add C type clamp or use sandbox) is than compressing numerous and diverse many of operation (bleeding off pressure iron) above, no matter be cast before clamping prepare or cast after dismantlement work be all very inconvenient, affect production efficiency.
Chinese invention patent CN2336895Y discloses a kind of sand-mould compressing iron clamping apparatus of the hulling modelling production line for the production of foundry goods, by driving lever, left link-type clamping mechanism and right connecting rod clamp mechanism and left clamping plate and right clamping plate composition, left, right clamping plate respectively with a left side, one end of right connecting rod clamp mechanism is connected, left, the other end of right connecting rod clamp mechanism is all connected with driving lever, driving lever is crossbeam, although this invention can realize preferably simultaneously, the mo(u)ld top half of sand mold compresses and the clamping of side type, but this invention complex structure, consumptive material is many, and in the time realizing the clamping of side type, must rely on external force to realize driving lever is pressed on foundary weight, simple and easy not.
Chinese invention patent CN 1015782B discloses in cast, solidify with cooling period and provide a kind of device of foundary weight and lateral support for what there is horizontal parting line without case sand mold part, this device comprises a foundary weight and clamping plate, the bottom surface of mo(u)ld bottom half is placed in a delivery instrument, this device also comprises substantially L-shaped arm, the arm of these two " L " shapes is arranged in the same vertical plane through sand mold part relative to one another, and in a horizontal plane, laterally mutually stagger and place, and be rotatably attached to foundary weight in position, although this invention can realize preferably simultaneously, the mo(u)ld top half of sand mold compresses and the clamping of side type, but clamping plate need attached fixed structure just can be clamped in sand mold side type, the equal more complicated of structure and manufacturing process.
Summary of the invention
The object of this invention is to provide a kind of self-floating foundary weight, this self-floating foundary weight can be realized the clamping of the compression of mo(u)ld top half and the side type of core group of core group simultaneously, and simple in structure, easy to make, need to be by external force, only rely on the deadweight of foundary weight just can realize the clamping of compression and the core group side type of core group mo(u)ld top half simultaneously.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of self-floating foundary weight for spacing core assembly pouring device, comprise foundary weight body, also comprise self-floating clamp mechanism, it is described before floating clamp mechanism comprises, after, left, right symmetrically arranged clamping device, each described clamping device comprises upper holder block, side pressing block and linkage structure, described linkage structure is movably connected on described foundary weight body, described upper holder block is connected on described linkage structure and under the Gravitative Loads power of described foundary weight body and vertically applies vertical active force and bear vertical reaction force, described side pressing block is connected in along continuous straight runs on described linkage structure and under described vertical reaction force and applies horizontal applied force and bear horizontal reacting force.
Further technical scheme, described linkage structure is clamp lever, described clamp lever is articulated and connected on described foundary weight body and rotates in perpendicular, the below that one end of described clamp lever extends to described foundary weight body forms the first lever arm, the below that the other end of described clamp lever extends to described the first lever arm forms the second lever arm, described upper holder block is connected on described the first lever arm and rotates in perpendicular, and described side pressing block is connected on described the second lever arm.
Further technical scheme, described the first lever arm has first arm of force, described the second lever arm has second arm of force, described upper holder block and the first lever arm have the first weight summation, described side pressing block and the second lever arm have the second weight summation, and the product of described the first weight summation and first arm of force is greater than the product of described the second weight summation and second arm of force.
Further technical scheme, described clamp lever is articulated and connected and in perpendicular, is rotated on described foundary weight body and take described the first rotating shaft as fulcrum by the first rotating shaft, described upper holder block is articulated and connected and is rotated in perpendicular in described the first lever arm and take described the second rotating shaft as fulcrum by the second rotating shaft, and described side pressing block is by adjustable being fixedly connected on described the second lever arm and can described the 3rd rotating shaft being that fulcrum is whole in the modulation of perpendicular inward turning of the 3rd rotating shaft.
Because technique scheme is used, the present invention compared with prior art has following advantages: in the time that foundary weight body presses down, make the Gravitative Loads power of foundary weight body drive upper holder block to compress the mo(u)ld top half of core group by linkage structure, make the reaction force that upper holder block is subject to drive side pressing block to clamp the side type of core group by linkage structure simultaneously, therefore can be in the time realizing the compression of mo(u)ld top half of core group the side type of Automatic-clamping core group, realization is spacing to core assembly pouring device (core group), in the time producing, only need an operation that bleeds off pressure iron can guarantee to compress mo(u)ld top half and clamp side type simultaneously, swell while avoiding pouring into a mould.So just can cancel original side clamp operation, reduce operational sequence, accelerate productive temp.
