Abstract
The utility model relates to a multiaspect core drawing device in a gravity diecasting, which is composed of a bottom board, hydraulic pressure core drawers and a diecasting pushing mechanism, wherein, the hydraulic pressure core drawers are fixed on the bottom board and are arranged correspondingly to the front, the back, the left, the right and the upper parts of the diecasting; the lower part of a diecasting is connected with the diecasting pushing mechanism through the bottom board. Casting cores in each direction can be drawn off through the control of the operation of the hydraulic pressure core drawers. The diecasting in a mould can be pushed out through the diecasting pushing mechanism to carry out the next casting after the core is drawn. The utility model can the complete large and complicated gravity diecasting needs multiaspect core drawing, and has the advantages of high work efficiency and low labour intensity.
Description
The utility model relates to the extraction device of casting spare core, particularly diecasting part multiaspect tube bundle extracting machine.
Diecasting since the power of loosing core require bigger, so to relatively more complicated cast member (hole, opening of different shape etc. are arranged in the foundry goods) the trouble of loosing core.Pressure casting machine can utilize its hydraulic pressure core-pulling device to carry out die to loose core, but its core-pulling device only can rectilinear motion, so can only extract the casting core of cast member both direction, the practicality of loosing core is not strong.To the multi-direction cast member of loosing core of need, now generally cast member is divided into several parts and casts respectively, loose core, and then be linked as an integral body.Time-consuming like this, take a lot of work, and the cast member mechanical performance is relatively poor.Monoblock cast is also arranged, the cast member that multiaspect is loosed core, but its core pulling method adopts and manually looses core in conjunction with hand tools, and it is low to form work efficiency, the shortcoming that labour intensity is big.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and providing a kind of can multiaspect loose core work efficiency height, the diecasting part multiaspect tube bundle extracting machine that labour intensity is low.
Solution of the present utility model is: diecasting part multiaspect tube bundle extracting machine comprises and the casting core-pulling device that is connected of core and the fixing base plate of core-pulling device, the front, rear, left and right and the equal correspondence of upper position that are characterized in cast member are provided with by the fixing hydraulic pressure core-pulling device of base plate, and the cast member ejecting mechanism that connects by base plate is arranged at the cast member bottom.The hydraulic pressure core-pulling device is connected with cast member, by controlling the motion of each hydraulic pressure core-pulling device, can simultaneously or extract the casting core of all directions separately out, after the casting core is extracted out, utilizes liftout attachment can eject the interior cast member of die.
In the solution of the present utility model: the hydraulic pressure core-pulling device can be fixed on the base plate by two stands, the hydraulic cylinder of hydraulic pressure core-pulling device is fixed on the two stands, the hydraulic cylinder two ends have loose core head and the connecting plate that is connected as a single entity and is moved by pull bar respectively, the head of loosing core is connected with the casting core, and slide in the dovetail groove of the sliding seat on being fixed on base plate, connecting plate is connected with piston rod, the outer dynamic control device of hydraulic cylinder.In the time of need loosing core, the head of loosing core is connected with the casting core, by power control unit piston rod is moved, and drives connecting plate and moves, and connecting plate drives the head of loosing core by pull bar and looses core, and makes the casting core move out die, finishes and looses core.This hydraulic pressure core-pulling device need be fixed on cast member top when loosing core, can fixedly vertical rod on base plate, and the fixing upper plate vertical in the vertical rod with base plate, the hydraulic pressure core-pulling device is fixed on the upper plate by two stands, and it is corresponding that its loose core head and top cast core.
The utility model advantage compared with prior art: because the utility model is fixed with the hydraulic pressure core-pulling device on the front, rear, left and right and the top of cast member, can extract the casting core of cast member all directions out by control hydraulic pressure core-pulling device, also can utilize ejecting mechanism that cast member is ejected mould after exhausting the casting core, cast next time, the utility model ability of loosing core is strong like this, can finish the multi-direction of complicated cast member and loose core, the efficient height, labor strength is low.
The utility model can further specify in conjunction with the accompanying drawings.
