Description
Technical field
The invention belongs to compression mod field, be specifically related to a kind of forming mechanism for reverse drawing die structure of die casting.
Background technology
Along with the development of die industry, need to meet different special formed products and can utilize casting forming.And be subject at present the limitation of Design of Dies, can only complete by the mode of slide block or neutron the moulding of falling withdrawing pattern of product, once run in the structure of product, there is the many places structure of falling withdrawing pattern, while especially having the phenomenon of the structure of falling withdrawing pattern in the direction perpendicular to movable mold die face, because board space or mould structure are limit, and cannot use slide block or middle minor structure time, conventionally need to change the moulding of product to realize the smooth demoulding of product.This is the very big limitation of Die Casting Industry to formed product, is unfavorable for the development of Die-Casting Industry.
Summary of the invention
For overcoming the deficiencies in the prior art, the object of the present invention is to provide a kind of forming mechanism for reverse drawing die structure of die casting, can make the smooth demoulding in the structure of falling withdrawing pattern perpendicular in movable mold die joint direction, avoid limitting because of product-forming, and the problem that cannot be shaped by die casting mode.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of forming mechanism for reverse drawing die structure of die casting, comprise die casting machine, mould and manipulator and manipulator electrical control cubicles, described manipulator electrical control cubicles is controlled described manipulator running, on described mould, be provided with knock pin, described die casting machine is connected with a liftout plate by a pull bar, and described liftout plate is connected with a return plate; On described mould, slideway is set, on described slideway, is provided with a moulding of falling withdrawing pattern and inserts; Described return plate is inserted and is connected with the described moulding of falling withdrawing pattern by a connecting rod.
Further, described manipulator is connected with a source of the gas, and described source of the gas is controlled by described manipulator electrical control cubicles, and one end of a blowning installation connects described source of the gas, and the other end is connected on described mould, can aim at described slideway and blow.
Preferably, described blowning installation is connected on described mould by quick connector.
Further, on described mould, be also provided with the return limit switch of inserting, for detection of the described moulding of falling withdrawing pattern, insert whether be returned to the end.
Preferably, between described liftout plate and described return plate, pass through screw lock.
Preferably, described connecting rod is inserted and is connected by engage thread with the described moulding of falling withdrawing pattern.
Operation principle of the present invention is as follows:
After mould die sinking, die casting machine drives pull bar to travel forward, make liftout plate eject connecting rod travels forward together with return plate, connecting rod is also inserted the moulding of falling withdrawing pattern drive to travel forward, the moulding of falling withdrawing pattern is inserted with extrusion pin common ejecting product, at this moment mechanical hand is clamped the material cake of product, upwards mention product, then along the direction of vertical die face, product is taken out from mold cavity; And source of the gas will be upper from being dynamically connected when mechanical hand is clamped product, aim at the slideway place air blowing that the moulding of falling withdrawing pattern is inserted, the booty in slideway is blown out; After product takes out, die casting machine drives pull bar to move back, pull bar retracts liftout plate, because liftout plate and return plate are that return plate also will return, and at this moment drive connecting rod be gone back by screw lock, connecting rod is inserted and is connected with the moulding of falling withdrawing pattern, the moulding of falling withdrawing pattern is inserted return, and the return limit switch of will being inserted when the moulding of falling withdrawing pattern is inserted on earth induction is sent signal and made the closed die-cast product that starts of mould, then starts to carry out next one circulation; If but insert while not being returned to the end when the moulding of falling withdrawing pattern, the return limit switch of inserting will be responded to less than signal, and mould will stop can not matched moulds, with the Anti-bump moulding of falling withdrawing pattern, inserts and mould.
Compared with prior art, the present invention has following beneficial effect:
Forming mechanism for reverse drawing die structure of die casting of the present invention, can make the smooth demoulding in the structure of falling withdrawing pattern perpendicular in movable mold die joint direction, avoids limitting because of product-forming, and the problem that cannot be shaped by die casting mode.
The present invention realizes shaping and the demoulding of the product moulding of falling withdrawing pattern by the mode with movably the moulding of falling withdrawing pattern is inserted; Should the moulding of falling withdrawing pattern insert with extrusion pin forward-reverse; And for preventing that the moulding of falling withdrawing pattern from inserting stuckly in slideway in moving process, in the present invention, be provided with blowning installation; For preventing that the moulding of falling withdrawing pattern from inserting, do not retreat the situation bed die matched moulds that puts in place, the generation of the mould phenomenon of will wounding, whether the present invention has also designed the return limit switch of inserting and has detected slide block and retreat and put in place.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
