A kind of extrusion casting machine
Technical field
The invention belongs to metallic article manufacturing technology field, particularly a kind of extrusion casting machine.
Background technology
At present, the technology of common die casting machine is quite ripe, and existing considerable recoverable amount, the injection mode of common die casting machine is broadly divided into three kinds, be respectively: its injection power is consistent with the mold clamping force direction and much smaller than mold clamping force, correlation technique is quite ripe when the horizontal injection mode of horizontal matched moulds, vertical matched moulds vertical injection mode, horizontal matched moulds vertical injection mode, preceding two kinds of clamping system injections, a kind of injection mode in back influences very little because not need to push feeding injection power less relatively.
Extrution casting technique further improves mechanical castings, forming ability, avoids even eliminates defectives such as bleb, shrinkage cavity with respect to traditional die carter artistic skill, reach purposes such as nearly moulding to the greatest extent, have Forming Quality preferably, be widely used in the demanding castings production of security performance such as automotive hub in developed country such as Japan-US.
And extrusion casting machine has only the ability that there are research and development in countries such as Japan, Switzerland and make at present, and it is identical that extrusion casting machine is compared the matched moulds part-structure with common die casting machine, generally adopts the Hydraulic Double toggle to drive.Its difference is the injection part, and what comparatively generally adopt at present is a kind of swing type injection mechanism, and this kind structure is comparatively complicated; Another kind is fixed injection chamber, and it adopts electromagnetic pump to water soup, and price is then comparatively expensive.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of extrusion casting machine is provided, this extrusion casint function realizes that preferably injection chamber waters the action of docking of soup and injection chamber and mould, and mould fills type, injection feeding function, and is convenient to dismounting and maintenance.

Compared with prior art, the invention has the beneficial effects as follows:
(1) the present invention is owing to make the injection mechanism body drive under the driving of oil cylinder at it, be moved horizontally to the mould correspondence position along guide rail, thereby can easily realize that injection chamber waters the action of docking of soup and injection chamber and mould, promptly the mode with injection mechanism body horizontal rectilinear motion breaks through the technical bottleneck of watering soup and mould contraposition, make foundry goods its have the cavity filling of injection feeding preferably energy;
(2) be connected on the connecting plate of frame by connecting bolt owing to injection body bracing frame among the present invention, be convenient to the dismounting and the maintenance of injection mechanism assembly;
(3) the present invention adopts oleo-gear and relevant hydraulic electric control system to realize the accurate contraposition of injection chamber and mould, guarantee the accurate contraposition performance of injection chamber and mould, make the metal of injection chamber water soup can accurately injection to mould, guarantee foundry goods mechanical property and processability preferably.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in detail:
Fig. 1 is an extrusion casting machine structural representation of the present invention;
Fig. 2 is the structural representation of injection mechanism assembly among the present invention;
Fig. 3 is the vertical view that the injection mechanism assembly is connected with the oleo-gear assembly among the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of extrusion casting machine of the present invention, comprise frame 1, be installed in the template system on frame 1 top and be installed in the injection mechanism assembly of frame 1 lower position, described template system comprise solid plate 2, with the moving platen 3 of solid plate 2 matched moulds, be connected with moving platen clamping 4 on the described moving platen 3, also be connected with adjustable formwork 23 on the moving platen clamping 4; Described injection mechanism assembly comprises injection mechanism body 5, injection mechanism body bracing frame 6, place injection chamber 7 on the injection mechanism body 5, be used for the injection punch head 8 of injection mo(u)lding, described injection mechanism body bracing frame 6 is provided with voltage supply and penetrates the guide rail 9 that mechanism body 5 moves horizontally, and a side of injection mechanism body 5 is connected with and drives the injection mechanism body driving oil cylinder 21 that injection mechanism body 5 moves along guide rail 9 horizontal linears.Drive oil cylinder 21 by the injection mechanism body and drive the injection mechanism assemblies and be moved horizontally to the position at mould 24 places, can better realize the action of docking of the soup work of watering of injection chamber 7 and injection chamber 7 and mould 24 along guide rail 9.
In addition, described injection mechanism assembly is connected on the frame 1, specifically with dismountable connected mode: described injection mechanism body bracing frame 6 is fixed on the connecting plate 11 of frame 1 by connecting bolt 10.By this dismountable separate type, to realize the dismounting and the maintenance work of injection mechanism assembly, simplified its installation, dismounting and maintenance process widely, reduce maintenance cost.
In the present invention, have insulation, heat-proof quality preferably in order to make injection chamber 7 interior metals water soup, to guarantee its mould molding effect preferably, the periphery of described injection chamber 7 is disposed with electric heating courage 12 and heat-insulating internal container 13 from the inside to the outside, chamber is the heating clamber that is used to heat between described electric heating courage 12 and injection chamber 7 outer walls, the chamber that forms between described heat-insulating internal container 13 and the electric heating courage 12 be used to be incubated, heat insulation vacuum chamber, be provided with the electric heating tube 14 that is used for the molten soup of heating of metal in the described heating clamber.
In the present invention, in order to make between injection punch head 8 and its driving oil cylinder 22 piston rods hot preferably isolation effect is arranged, and the deflection deformation that produces when injection punch head drives oil cylinder 22 piston rod pressurizeds is to the influence of piston rod construction stability, the lower position of described injection punch head 8 is provided with brace summer 15, described injection punch head driving oil cylinder 22 inversions that are used to drive injection punch head 8 motions, the piston rod that this inverted injection punch head drives oil cylinder 22 is connected with injection punch head 8 by described brace summer 15, and the outside of this brace summer 15 also is provided with brace summer fairlead 16.
As shown in Figure 3, for injection chamber 7 is docked with the accurate of mould 24, one side of described injection mechanism body 5 is provided with two groups of oleo-gear assemblies, described oleo-gear assembly comprises oleo-gear 17, damper positioning sleeve 18 and locking nut 19, damper holder 20, described oleo-gear 17 is connected on the injection mechanism body bracing frame 6 by damper positioning sleeve 18 and locking nut 19, damper holder 20, and it places the injection mechanism body to drive the opposite side position of oil cylinder 21.When driving oil cylinder 21 driving injection mechanism bodies 5, the injection mechanism body on guide rail 9, does rectilinear motion, when running into oleo-gear 17, electric-control system receives telecommunications command injection mechanism body and drives oil cylinder 21 decelerations, when running into oleo-gear positioning sleeve 18 at last, its speed is reduced to zero (injection mechanism body driving this moment oil cylinder 21 flows are zero), thereby realizes that injection chamber docks with the accurate of mould 24.
