Description
Technical field
The utility model relates to mould of die casting machine technical field, relates in particular to a kind of secondary ejecting mechanism for mould.
Background technology
The ejecting mechanism of the general employing of the Zinc alloy casting demoulding that existing horizontal hot chamber machine is produced.After die sinking, die casting machine discharge arm ejects, and discharge arm promotes mould stripper, by being connected to thimble on stripper along with stripper moves forward together.Thereby drive thimble to stretch out the pushing method that product is ejected to die.The finding thin for wall can cause thimble location conflicts, ejecting product distortion, easily broken, the easy snap gauge phenomenon of thimble.Owing to being subject to product design feature affects, an ejecting mechanism cannot arrange rational thimble and eject position.
Utility model content
The purpose of this utility model is to provide a kind of secondary ejecting mechanism for mould, to solve the defect of existing traditional ejecting mechanism, by increasing by twice top board, push pedal, stick up the winding machines such as top board, connecting rod and eject for twice, can not affect the outward appearance of product, structure and dimensional requirement, improve and eject distortion, snap gauge phenomenon.
To achieve these goals, the technical scheme that the utility model is taked is:
For a secondary ejecting mechanism for mould, be applied to the Thin wall zinc alloy-steel casting mould of horizontal hot chamber machine, described mould comprises moving platen and solid plate, and described moving platen has mavable module core, and described solid plate has fixed mold core, wherein:
Comprise push pedal, scraping wings, the first liftout plate, the second liftout plate, connecting rod, stick up top board, position-limit mechanism and thimble;
Described the first liftout plate is fixed in described push pedal, described the second liftout plate is arranged on described the first liftout plate, described stick up top board by a fulcrum be located at rotationally described the first liftout plate a side and described in stick up top board Plane of rotation perpendicular to described the second liftout plate, thereby the rotation that described position-limit mechanism sticks up top board for sticking up the displacement of top board one end described in limiting described in realizing;
Described connecting rod is fixed on described the first liftout plate, and described scraping wings is fixedly connected with described connecting rod, and described scraping wings and described the first liftout plate and described push pedal are connected as a single entity by described connecting rod;
Described thimble is fixed on described the second liftout plate.
The above-mentioned secondary ejecting mechanism for mould, wherein, the rationed marketing that is limited of described position-limit mechanism, described restriction pin is fixed on described mavable module core.
The above-mentioned secondary ejecting mechanism for mould, wherein, described fulcrum is not in described center of sticking up top board.
The above-mentioned secondary ejecting mechanism for mould, wherein, described mould also comprises mould pin, for the bottom support of described mould or padded.
Compared with prior art, advantage applies of the present utility model exists: twice ejecting mechanism ejects and make product separated with core rod by one section, and it is whole contact product and runner that pusher version promotes product, stressed even.By two sections, eject and be not subject to dynamic model and core rod to eject die under affecting product again.This mode can solve the problems such as distortion that product cannot thimble reasonable in design position causes because of reasons in structure, snap gauge effectively.
Accompanying drawing explanation
Fig. 1 is that the utility model is for the structural representation of the secondary ejecting mechanism of mould;
To be the utility model eject schematic diagram for the first paragraph of the secondary ejecting mechanism of mould to Fig. 2;
To be the utility model eject schematic diagram for the second segment of the secondary ejecting mechanism of mould to Fig. 3.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
The utility model, for the secondary ejecting mechanism of mould, is applied to the Thin wall zinc alloy-steel casting mould of horizontal hot chamber machine, and mould comprises moving platen 3 and solid plate 1, and moving platen 3 has mavable module core 12, and solid plate 1 has fixed mold core 14.Shown in Figure 1, the utility model secondary ejecting mechanism comprises push pedal 7, scraping wings 2, the first liftout plate 6, the second liftout plate 5, connecting rod 4, sticks up top board 8, position-limit mechanism and thimble 10.
The first liftout plate 6 is fixed in push pedal 7, the second liftout plate 5 is arranged on the first liftout plate 6, stick up Plane of rotation that top board 8 is located at rotationally a side of the first liftout plate 6 and stuck up top board 8 by a fulcrum O perpendicular to the second liftout plate 5, thereby position-limit mechanism sticks up the displacement of top board 8 one end for limiting, realize the rotation of sticking up top board 8.Connecting rod 4 is fixed on the first liftout plate 6, and scraping wings 2 is fixedly connected with connecting rod 4, and scraping wings 2 and the first liftout plate 6 and push pedal 7 are connected as a single entity by connecting rod 4.Thimble 10 is fixed on the second liftout plate 5.
In preferred embodiment of the present utility model, the position-limit mechanism rationed marketing 11 that is limited, limits pin 11 and is fixed on mavable module core 12.Wherein, fulcrum O can be in the center of sticking up top board 8, referring to diagram,
So the benefit of design is to make to stick up top board 8 can under the driving of an enough little power, be rotated.
Continuation is referring to diagram, further preferred, and this mould also comprises mould pin 9, for the bottom support of mould or padded.
In twice ejector mechanism die of the utility model, scraping wings 2 is used screw and connecting rod 4 to fix, and scraping wings 2 and liftout plate 6 and push pedal 2 are connected as a single entity.
When die sinking, the discharge arm of die casting machine ejects and promotes push pedal 7, and the scraping wings 2 that drives the first liftout plate 6 to connect moves, and the product 16 that manufacture is moved with scraping wings 2 with runner 15 position integral body, product 16 is separated with the core rod 13 of mould, realizes first paragraph and ejects.
After first paragraph has pushed up, the discharge arm of die casting machine continues to eject, promote push pedal 7, now, stick up top board 8 one end and push up spacer pin 11, stick up top board 8 other end perks, under the active force of lever principle, promote the second liftout plate 5, by the thimble 10 being fixed on the second liftout plate 5, runner 15 is ejected, product 16 links together with runner, product 16 also with runner 15 by the mavable module core 12 of ejection die completely.
In sum, use the utility model secondary ejecting mechanism, by stick up top board 8 and the second liftout plate and connecting rod 4, scraping wings 2 in original ejecting mechanism increase, realized segmentation and ejected.The utility model can solve the problems such as distortion that product cannot thimble reasonable in design position causes because of reasons in structure, snap gauge effectively.
The foregoing is only the utility model preferred embodiment; not thereby limit embodiment of the present utility model and protection domain; to those skilled in the art; should recognize that being equal to that all utilization the utility model descriptions and diagramatic content done replace and the resulting scheme of apparent variation, all should be included in protection domain of the present utility model.
