Abstract
The invention discloses a casting die enabling a workpiece to be synchronously ejected in the die opening process. The casting die enabling the workpiece to be synchronously ejected in the die opening process mainly comprises a bottom board (1), a lower die (2), a top board (3), an ejection ring (4), returning rods (5), a lantern ring (6), an upper die (7), a die core (8), a screw (9), a screw (10), a screw (11), mandrels (12) and springs (13). The lower die (2) is fixed to the bottom board (1), the die core (8) is fixed to the lower die (2), and an ejection mechanism is placed in a cavity formed by the bottom board (1), the lower die (2) and the die core (8); the ejection ring (4), the returning rods (5) and the mandrels (12) are connected with the top board (3), each mandrel (12) is sleeved with the corresponding spring (13) which is placed in a counter bore in the bottom board (1), the mandrels (12), the springs (13) and the returning rods (5) are evenly distributed on the top board (3) according to the actual requirements, and therefore the die opening synchronous ejection mechanism is formed by the parts; the lantern ring (6) is connected to the lower die (2). When the upper die (7) is closed, the returning rods (5) are pressed downwards, pressure is transmitted to the springs (13) through the top board (3) and the mandrels (12), and therefore the springs (13) are compressed. When the upper die (7) is opened, the springs (13) extend, and ejection force is transmitted to the workpiece through the mandrels (12), the top board (3) and the ejection ring (4) so that the workpiece can be ejected synchronously when the die is opened.
Description
Technical field
The present invention relates to a kind of casting mould, relate to specifically the casting mould that a kind of die sinking synchronously ejects workpiece.
Background technology
In Foundry Production, workpiece ejected diversified mode.In the mould of upper lower open die, often use following pushing method: in die sinking process, utilize patrix that workpiece is taken out of, then the push rod by patrix ejects workpiece, takes off workpiece, and liftout attachment is not set on which counterdie.
There is certain defect in above-mentioned pushing method, when counterdie draft angle larger, required withdrawing pattern power hour, aforesaid way can be realized die sinking smoothly, yet, when counterdie draft angle less, when required withdrawing pattern power is larger, aforesaid way is just difficult to smooth die sinking, occurs that patrix cannot take workpiece out of or break the phenomenons such as workpiece weak part, cannot steady and continuous produce.This just need to increase liftout attachment on counterdie.
At present, the counterdie liftout attachment increasing on above-mentioned pushing method mainly contains hydraulic pressure and two kinds of modes of machinery.Because operating ambient temperature is very high, hydraulic cylinder must be arranged on mould outside, and structure is loaded down with trivial details, takes up room larger, and functional reliability is lower, and is difficult to guarantee that counterdie liftout attachment synchronously ejects when patrix is opened.One of mechanical system is by rigid member, mould opening force to be passed to counterdie liftout attachment when patrix is opened, realization ejects workpiece, when this mode can realize patrix unlatching, counterdie liftout attachment synchronously ejects, but, this complicated structure, part processing precision is had relatively high expectations, and matching requirements are also higher, and job stability is difficult to guarantee.Therefore, must improve counterdie liftout attachment, design a kind of reasonable, practical ejecting mechanism.
Summary of the invention
The object of the invention is for existing casting mould counterdie liftout attachment above shortcomings, provide a kind of die sinking having improved synchronously to eject the casting mould of workpiece.When this mould can be realized the unlatching of casting mould patrix effectively, counterdie liftout attachment synchronously ejects workpiece.
Technical scheme of the present invention is: described mould mainly comprises base plate, counterdie, top board, ejection ring, return bar, the collar, patrix, core rod, screw, axle and spring; Counterdie is fixed on base plate, and core rod is fixed on counterdie by screw, and ejecting mechanism is positioned in the cavity being formed by base plate, counterdie and core rod; Ejection ring, axle link together by screw and top board, spring housing is in axle, and be positioned in the counterbore of base plate, the utilization of return bar is threadedly connected on top board, described axle, spring and return bar according to actual needs on top board uniform several, these parts form the synchronous ejecting mechanism of die sinking together; Collar utilization is threadedly connected on counterdie.
Described ejection ring is tubular construction, is arranged in the annular groove of counterdie and core rod formation; Ejection ring adopts matched in clearance with contacting of counterdie, core rod, and the value of matched in clearance is at 0.1 ~ 0.2mm.The centre bore bottom of described counterdie is designed to " concavo-convex " structure, at the correspondence position of top board, offers scallop hole, top board is through in " concavo-convex " structure of counterdie.The collar is installed on counterdie, and after Ccope closing machine, collar upper surface and patrix laminating, play sealing function.Described spring adopts special high temperature resistant spring, can be in more than 400 ℃ environment steady operation for a long time.
During described Ccope closing machine, push back a bar downwards, by top board and axle, pressure is passed to spring, make spring-compressed.When patrix is opened, spring extends, and by axle, top board and ejection ring, ejecting force is passed to workpiece, synchronously ejecting workpiece while realizing die sinking.
Accompanying drawing explanation
Fig. 1 is the casting mould schematic diagram that die sinking synchronously ejects workpiece;
Fig. 2 is casting mould counterdie and the top board structure schematic diagram that die sinking synchronously ejects workpiece.
The specific embodiment
Below in conjunction with accompanying drawing, with regard to the specific embodiment, be elaborated.
Shown in Fig. 1, for die sinking synchronously ejects the casting mould schematic diagram of workpiece, mould mainly comprises base plate 1, counterdie 2, top board 3, ejection ring 4, return bar 5, the collar 6, patrix 7, core rod 8, screw 9, screw 10, screw 11, axle 12 and spring 13; Counterdie 2 is fixed on base plate 1, and core rod 8 is fixed on counterdie 2 by screw 11, and ejecting mechanism is positioned in the cavity being formed by base plate 1, counterdie 2 and core rod 8; Ejection ring 4 links together by screw 9 and top board 3, axle 12 links together by screw 10 and top board 3, spring 13 is enclosed within axle 12, and be positioned in the counterbore of base plate 1, return bar 5 utilizes and is threadedly connected on top board 3, described axle 12, spring 13 and return bar 5 according to actual needs on top board 3 uniform several, these parts form the synchronous ejecting mechanism of die sinking together; The collar 6 utilizes and is threadedly connected on counterdie 2.
