Description
Technical field
The present invention relates to a kind of Casting Equipment.When particularly relating to a kind of foundry production that is used for mechanical industry and will dissolve good alloy solution and pour into the casting mold that metal makes, under the gravity effect, finish and fill type and solidify and obtain the gravity force casting machine of method for casting.
Background technology
At present, the good metallic solution pouring procedure majority that dissolves in the Casting Equipment is the pouring procedure of manual operation Dumpage type, and its labour intensity of this traditional methods is big, production efficiency is low and the difficult quality guarantee of foundry goods; At present a kind of employing being arranged also is the hydraulic pressure and the mechanically operated casting machine of purpose to reduce labor intensity and to boost productivity, as disclosed in the Chinese patent specification 990220647.8 " a kind of casting machine ", as shown in Figure 5, it is by comprising the casting ladle frame, topple over arm and topple over control device, it also comprises an operation control system, this system is by hydraulic power control system 1,2, worktable lifting mechanism 3, slew gear 4, manually auxiliary compensation arrangement 8 and cart walking mechanism 12 constitute, wherein, hydraulic power control system 2 is fixed on the vehicle frame 11, worktable lifting mechanism 3 is the billy gate formula, and by fixed mount, adjustable shelf and sprocket wheel are formed, fixed mount is installed in vehicle frame 11 front portions, slew gear 4 is a vertical shaft hinge bodies structure, be connected with workbench 9 and worktable lifting mechanism 3 respectively, the anterior interior and upper end of workbench 9 is respectively equipped with track, topple over arm 6 and be the sleeve bar type structure, divide into support, forequarter is equipped with roller under the support, manually auxiliary compensation arrangement 8 upper ends are vertical shaft type brakes, go up with the support of toppling over below the arm 6 and fix, the lower end is that both sides have the frame structure that moves wheel, cart walking mechanism 12 is a roller type, worktable lifting mechanism 3, slew gear 4, topple over arm 6, the motion of the brake of manually auxiliary compensation arrangement 8 is transmitted hydraulic power by hydraulic control system 2, and via controller 5 controls.
It is toppled over arm and topples over operating mechanism and controlled by an operation control system, this system is by worktable lifting mechanism, slew gear, manually auxiliary compensation arrangement and cart walking mechanism constitute, whole device is the travelling car formula, workbench can horizontally rotate by slew gear, liftable is toppled over scalable, the upset of arm again, thereby realizes the upset of casting ladle frame, each mainly moves and is the hydraulic machinery action and is aided with manual control, can finish the cast task accurately, flexibly, safely and efficiently.
Above-mentioned yet " a kind of casting machine " its shortcoming is because the metal die on its workbench of casting cycle is to vert simultaneously, thereby can not discharge the residual gas in the die cavity effectively, and the quality of foundry goods is difficult to guarantee equally.
Summary of the invention
Purpose of the present invention is exactly in order to overcome above-mentioned weak point of the prior art, a kind of residual gas that both can discharge effectively in the die cavity is provided, when reducing the metallic solution cast splash and eddy current with the quality that improves foundry goods, not only have simultaneously good to metal die cool off and mold cavity surface dip-coating function to improve die life but also to be convenient to the gravity force casting machine of the casting mold demoulding.
The gravity-type casting machine has been applied to casting industry abroad, all produce as the CMH company of the U.S., gondola IMR company, and their product all is all-hydraulic, Automatic Control, to put all automatic control of operations such as core, cast, cooling, inloading part, mold cleaning spray paint and finish, only need one man operation; Yet cost an arm and a leg one about seven, 80,000 dollars of imports.
The present invention effectively utilizes to finish under the gravity effect and fills type and solidify and obtain method for casting and be referred to as gravitation casting method, is called the permanent mold casting method again.The objective of the invention is under the medium and small manufacturing enterprise condition that especially labour of private enterprise is rich, labour cost is lower according to China's national situation, both had the performance requirement of external like product and only to be the operator increase to three people and its cost by a people only realizes that for the method for fractional steps gravity force casting machine of about 10 following structure of import equipment it comprises the dislocation roller devices of Working gantry, casting workbench, metal die, mould by providing a kind of.
Described Working gantry is one to have the closed-in construction of " П " font of sill and at least four footing, be provided with the frame that is fixedly clamped that is used to clamp described metal die above described " П " font Working gantry, what clamp adjustable shelf and clamp cylinder can be the casting workbench adjustable shelf that the center spins upside down along the pivot of the described frame that is fixedly clamped also, propping up below by the bearing pin pivot of described casting workbench adjustable shelf connects a piston rod that is used to spin upside down the cylinder of described workbench adjustable shelf, and the sill of the lower end of described cylinder by bearing pin and described Working gantry pivot mutually props up connection; The other end of described " П " font Working gantry fixedly installs a cooling casing, and a side of described cooling casing fixedly installs a support that has a bearing pin, and described bearing pin pivot props up and connects a cooling frame cylinder; The bottom of described cooling casing fixedly installs an agitator that is used to stir described metal die cooling water that has a motor.
