Abstract
The utility model discloses the two bar extrusion oil cylinder of a kind of transfer mold, comprise the cylinder body of back-end closure, be fixed on the end cap of cylinder body front end, piston rod and piston, described cylinder body at least has the inner chamber of two axis being parallel, piston rod to be arranged in described inner chamber and to stretch out outside cylinder body, piston is fixed on described piston rod rear end and internal chamber wall is slidably matched, the confession oil duct that cylinder body is provided with main oil inlet hole, is communicated with main oil inlet hole, described is provided with between oil duct and described inner chamber the branch road oil duct providing hydraulic oil to realize piston rod movement to inner chamber.The utility model by arranging two or more inner chambers in cylinder body, and in inner chamber relative set piston, piston rod, multiple plug or slide block can be connected thus, promotion plug or slide block stretch into transfer mold inner chamber liquid towards die-casting material and carry out squeeze job, thus simplify the overall structure of oil cylinder, improve operating efficiency.
Description
Technical field
The utility model relates to the two bar extrusion oil cylinder of a kind of transfer mold.
Background technique
During die casting operation, for improving the internal quality of casting, reducing casting defect, usually needing liquid towards die-casting material to carry out extrusion operation, make cast-internal structure organization more tight.Extrusion operation many employings oil cylinder pushing plug or slide block stretch in liquid die-casting material, because the die castings structure had is comparatively complicated, two or more plug or slide block need be adopted to extrude simultaneously, now adopt the words of single only conventional oil cylinder, promote two or more plug, then need to arrange link in addition, plug or slide block are linked to be entirety and synchronously push in dies cavity, oil cylinder certainly will be caused integrally-built complicated.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, a kind of simplified structure is provided, realize multiple plug or slide block simultaneously liquid towards die-casting material carry out the two bar extrusion oil cylinder of transfer mold of squeeze job.
The utility model solves the technological scheme that its technical problem adopts: the two bar extrusion oil cylinder of a kind of transfer mold, comprise the cylinder body of back-end closure, be fixed on the end cap of cylinder body front end, piston rod and piston, described cylinder body at least has the inner chamber of two axis being parallel, piston rod to be arranged in described inner chamber and to stretch out outside cylinder body, piston is fixed on described piston rod rear end and internal chamber wall is slidably matched, cylinder body is provided with main oil inlet hole, what be communicated with main oil inlet hole supplies oil duct, described is provided with between oil duct and described inner chamber the branch road oil duct providing hydraulic oil to realize piston rod movement to inner chamber.
Preferably, described inner chamber is two that arrange up and down, and the corresponding inner chamber of piston rod is arranged.
Further, the guide sleeve guiding the steady movement of piston rod is provided with between described end cap and piston rod.
The beneficial effects of the utility model are: the utility model by arranging two or more inner chambers in cylinder body, and in inner chamber relative set piston, piston rod, multiple plug or slide block can be connected thus, promotion plug or slide block stretch into transfer mold inner chamber liquid towards die-casting material and carry out squeeze job, thus simplify the overall structure of oil cylinder, improve operating efficiency.
Accompanying drawing explanation

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
The two bar extrusion oil cylinder of a kind of transfer mold as shown in Figure 1 and Figure 2, comprise the cylinder body 1 of back-end closure, be fixed on the end cap 2 of cylinder body 1 front end, piston rod 3 and piston 4, be provided with the guide sleeve 9 guiding the steady movement of piston rod 3 between described end cap 2 and piston rod 3, piston rod 3 and guide sleeve 9 endoporus are slidably matched.
Described cylinder body 1 has the inner chamber 5 of two axis being parallel, one end is set in described inner chamber 5 respectively and stretches out piston rod 3 outside cylinder body 1, piston 4 is fixed on described piston rod 3 rear end and inner chamber 5 wall is slidably matched, cylinder body 1 is provided with main oil inlet hole 6, what be communicated with main oil inlet hole 6 supplies oil duct 7, described for being provided with the branch road oil duct 8 providing hydraulic oil to realize piston rod 3 to move to inner chamber 5 between oil duct 7 and described inner chamber 5, hydraulic oil enters cylinder body 1 by main oil inlet hole 6, through shunting to two branch road oil ducts 8 for oil duct 7 simultaneously, then enter the synchronous piston 4 that promotes of two inner chambers 5 to move, piston rod 3 drives plug or slide block to realize the squeeze job of liquid towards die-casting material,
The utility model by arranging two or more inner chambers 5 in cylinder body 1, and in inner chamber 5 relative set piston 4, piston rod 3, multiple plug or slide block can be connected thus, promotion plug or slide block stretch into transfer mold inner chamber liquid towards die-casting material and carry out squeeze job, thus simplify the overall structure of oil cylinder, improve operating efficiency.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
