Description
Technical field
The present invention relates to die casting technical field, more particularly to a kind of casing ejecting structure for die casting.
Background technology
Common casing ejecting structure ejects casing from pin as shown in Fig. 2, directly promote casing by push plate, this
In kind of mode of operation, the length of casing and pin can be very long, and when operation can not control ejecting force very well, be easy to cause product damage
It is bad, simultaneously because casing and pin are long, casing and pin service life can be greatly reduced, to solve the above-mentioned problems, design
A kind of new casing ejecting structure is necessary.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of casing ejecting structure for die casting, have structure
Simply, length reduction easy for installation, easily disassembled, by arranging push rod, pin and casing, so as to avoid thrust excessive
And damage of product is caused, while the features such as also increase the service life of pin and casing.
The technical solution adopted by the present invention to solve the technical problems is：A kind of casing for die casting is provided to eject
Structure, including mold core, die holder and upper mounted plate, embedded on the die holder to be equipped with mold core, the die holder lower disposed has
Through hole, the through hole are located at below mold core, and through hole lower end is equipped with pin fixed plate, vertically-mounted in the pin fixed plate to have
Pin is equipped with casing push plate in the pin fixed plate, the set being socketed on pin is equipped in the casing push plate
Pipe, is equipped with push plate below the die holder, the vertically-mounted push rod for having upper end mutually to be pushed up with casing push plate in the push plate.
The push plate upper surface is equipped with the upper mounted plate of fixed push rod.
The through hole of the pin fixed plate lower face installation pin is equipped with the plug of fixator pins.
The pin fixed plate is connected with die holder by pin, is adopted between the through hole of the plug and pin fixed plate
It is threadedly coupled.
The casing push plate lower face is disposed with the casing fixed plate of embedded pin dead plate upper end Middle face, described
It is connected between casing fixed plate and casing push plate by attachment screw.
It is mutually pushed up with casing push plate through pin fixed plate and casing fixed plate the push rod upper end.
Old-fashioned structure is long due to casing ejection in process of production, and casing, pin are easily stuck, and spare part is of large quantities,
Of high cost and replacement is frequent, seriously affects normal production.New construction drives casing push plate by the conversion of power using mandril push plate
Play the role of casing ejection, do not allow since casing, cotter length are short in production process it is flexible, in casing active procedure just not
Can be stuck, the service life of casing and pin is considerably increased, improves productive temp.
Advantageous effect：The present invention relates to a kind of casing ejecting structures for die casting, have simple in structure, installation side
Just length reduction, easily disassembled, by arranging push rod, pin and casing, product is caused so as to avoid thrust excessive
Damage, while the features such as also increase the service life of pin and casing.

Specific embodiment
With reference to specific embodiment, the present invention is further explained.It is to be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, people in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Scope.
Embodiments of the present invention are related to a kind of casing ejecting structure for die casting, as shown in Fig. 1-2, including
Mold core 1, die holder 2 and upper mounted plate 3, on the die holder 2 insertion mold core 1 is installed, 2 lower disposed of die holder has logical
Hole, the through hole are located at 1 lower section of mold core, and through hole lower end is equipped with pin fixed plate 12, pacifies vertically in the pin fixed plate 12
Equipped with pin 5, casing push plate 10 in the pin fixed plate 12 is installed, is equipped with and is socketed in the casing push plate 6
Casing 6 on pin 5,2 lower section of the die holder are equipped with push plate 4, vertically-mounted in the push plate 4 to have upper end to be pushed away with casing
The push rod 9 on 10 phase top of plate.
4 upper surface of push plate is equipped with the upper mounted plate 3 of fixed push rod 9.
The through hole of 12 lower face of the pin fixed plate installation pin 5 is equipped with the plug 13 of fixator pins 5.
The pin fixed plate 12 is connected with die holder 2 by pin, and the plug 13 is logical with pin fixed plate 12
Using threaded connection between hole.
10 lower face of casing push plate is disposed with the casing fixed plate 11 in the middle part of embedded 12 upper surface of pin fixed plate,
It is connected between the casing fixed plate 11 and casing push plate 10 by attachment screw.
9 upper end of push rod passes through pin fixed plate 12 and casing fixed plate 11 and 10 phase top of casing push plate.
Embodiment
When needing to deviate from casing 6, start push plate 4 first, push plate 4 promotes push rod 9, and the upper end of push rod 9 promotes
Casing push plate 10, casing push plate 10 promote casing 6 so that and casing 6 is separated with pin 5, compared with the structure of script, this structure profit
With push rod 9 and push plate 4 casing push plate 10 is driven to play the role of casing 6 to eject, due to casing 6,7 length of pin in production process
It is short do not allow it is flexible, would not be stuck in 6 active procedure of casing, considerably increase the service life of casing 6 and pin 5, improve life
Produce beat.
