Description
Technical field
The present invention relates to mould of die casting machine fields, and in particular to a kind of die casting machine cavity jacking structure.
Background technology
Die casting is a major class in mold.In recent years, with the rapid development of China's automobile, motorcycle industry,
Die Casting Industry has welcome the new period of development.But at the same time, also to the comprehensive mechanical property of die casting, service life and mold
More stringent requirements are proposed for structure etc..
Die casting is a kind of production process of precision, however the final size change of die casting can be influenced by having several factors but
Change.Change in size can be divided into linear change (mainly causing due to shrinking), the mobile dislocation between mold, die parting line, casting again
Part and mold warpage, die casting parameter, core pulling and draft angle etc..But there is any that must remember the variation of the final size of die casting only
It is to depend in part on mould and die accuracy, it also has close relationship with following factor：Mold in press casting procedure temperature it is normal
The structure etc. of fluctuation, injection temperature, cooling velocity, casting stress release and mold.To reduce the change in size of final products,
Production process is must be strictly controlled, mould structure is optimized.
In the prior art, all die casting machines all only have dynamic die liftout mechanism, many products be when needing cavity jacking
It tries every possible means on mold：Such as behind stationary mould for mould plate plus spring, cylinder ejector either dynamic model mandril increase back-off or by cunning
Block strength makes product stay in dynamic model etc. by force；These methods are no doubt effective, but increasingly complex, the thickness for often becoming mould structure
The thickness of change is big, and production stability is bad
Invention content
Shortcoming in for the above-mentioned prior art, the present invention provide a kind of die casting machine cavity jacking structure, structure
Simply, it automatically controls.
In order to achieve the above object, present invention employs following technical schemes：
A kind of die casting machine cavity jacking structure, including solid plate and the cover half that is fixed on solid plate, it is characterised in that：
There are one cavity jacking mechanisms for setting on the cover half, and the cavity jacking mechanism is by being fixed positioned on the solid plate
Multigroup nitrogen gas spring driving, every group of nitrogen gas spring is respectively connected with individual trachea, and is provided with list on each trachea
Only hand control valve or electrically-controlled valve.
Further, the cavity jacking mechanism includes top plate, and the roof movement is set to the recessed of the cover half bottom
In slot, the mandril that can be stretched into the cover half cavity is fixed on the top plate.
Further, the top plate corresponds to two groups of nitrogen gas springs, which acts simultaneously, described in pushing
Movement of roof.
Further, the electrically-controlled valve accesses the controller of die casting machine by signal control line, and each described automatically controlled
Valve is respectively arranged with number, and the controller can control the electrically-controlled valve of specified number.
Beneficial effects of the present invention include：Fixed mould structure is simple, using nitrogen gas spring, and with the online control of die casting machine, from
Dynamicization degree is high, and can not have to the position for changing driving mechanism, and arbitrary combination control meets the needs of different molds.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the vertical view of solid plate in the present invention；
Fig. 3 is the upward view of solid plate in the present invention.
Specific implementation mode
With reference to specific embodiment and attached drawing, present invention be described in more detail.
A kind of die casting machine cavity jacking structure as shown in Figure 1, including solid plate 1 and being fixed on solid plate 1 are determined
Mould 2.There are one cavity jacking mechanisms for setting on the cover half 2, and the cavity jacking mechanism is by being fixed positioned in the cover half
Multigroup nitrogen gas spring 3 on plate 1 drives.Every group of nitrogen gas spring 3 is respectively connected with individual trachea 4, and each trachea 4
On be provided with individual hand control valve or electrically-controlled valve.
Cavity jacking mechanism includes top plate 6 described in a kind of embodiment of the present invention, and the top plate 6 be movably set in it is described
In the groove of 2 bottom of cover half.The mandril 7 that can be stretched into 2 cavity of the cover half is fixed on the top plate 6.6 lower section of the top plate
Corresponding two groups of nitrogen gas springs 3, two groups of nitrogen gas springs 3 can act simultaneously, to push the movement of the top plate 6 to be transported in groove
It is dynamic, to drive mandril 7 to eject the workpiece in 2 cavity of cover half.
The switch valve on trachea 4 in the present embodiment is all made of the electrically-controlled valve, and the electrically-controlled valve passes through signal
Control line accesses the controller of die casting machine, and each electrically-controlled valve is respectively arranged with number, and the controller, which can control, to be referred to
The electrically-controlled valve for the number of delimiting the organizational structure.Top plate 6 has corresponded to two groups of nitrogen gas springs 3 in the present embodiment, then correspondence is opened in setting in the controller
The number of two groups of nitrogen gas springs 3 then only has the nitrogen gas spring 3 of this two groups specified numbers to act, and acts simultaneously, remaining
The nitrogen gas spring 3 for not controlling unlatching does not act then, keeps original contraction state.Nitrogen gas spring 3 is compared to ordinary elasticity
For part, has the characteristics that small, long lifespan, elasticity are big, stroke is long, do not need pretightning force, stable working, by compressed nitrogen
Gas is simple and easy to get as power source, at low cost.
It is provided for the embodiments of the invention technical solution above to be described in detail, specific case used herein
The principle and embodiment of the embodiment of the present invention are expounded, the explanation of above example is only applicable to help to understand this
The principle of inventive embodiments；Meanwhile for those of ordinary skill in the art, embodiment according to the present invention, in specific embodiment party
There will be changes in formula and application range, in conclusion the content of the present specification should not be construed as limiting the invention.
