Abstract
The utility model discloses primary-secondary module cylinder of an injection molding machine, which comprises a module-closing lower cover, a module-closing upper cover, a module-closing cylinder and a module-closing core shaft, wherein one end of the module-closing lower cover is provided with an A oil opening; the A oil opening is communicated with an A space which is arranged among the module-closing lower cover, the module-closing core shaft and the module-closing core shaft; one end of the module-closing upper cover is provided with a B oil opening; the B oil opening is communicated with a B space which is arranged among the module-closing upper cover, the module-closing core shaft and the module-closing cylinder; the module-closing cylinder is also internally provided with a quick core shaft; the quick core shaft is fixed on the module-closing lower cover through a connecting cover; the module-closing core shaft is sleeved on the quick core shaft; the module-closing core shaft is provided with a C oil opening; and the C oil opening is communicated with a C space between the module-closing core shaft and the quick core shaft. The primary-secondary module cylinder can fast open and close the module, and has the advantages of small volume and low manufacture cost, compared with the existing machine.
Description
Technical field
The utility model relates to a kind of parts of injection machine, specifically relates to the primary and secondary mould cylinder of injection machine.
Background technology
The existing hydraulic cylinder of injection machine is formed by closing the mould lower cover, close the mould loam cake, close the mould cylinder barrel and closing the core rod axle, in the time of need carrying out the Guan Mo action as shown in Figure 1, the oil-feed of A hydraulic fluid port, the oil return of B hydraulic fluid port is because the A space is bigger, when oil pump capacity fixedly the time, the time that oil-feed needs is long, and pass mould speed is slow.In order to solve the slow-footed problem of switch mould, normally increase the action that sub-cylinder body drives master cylinder by the outside, so, can cause the spatial volume of machine to increase undoubtedly, also can increase loss simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of primary and secondary mould cylinder that closes the fireballing injection machine of mould.
The technical scheme that its technical problem that solves the utility model adopts is: the primary and secondary mould cylinder of injection machine, comprise and close the mould lower cover, close the mould loam cake, close the mould cylinder barrel and close the core rod axle, mould lower cover one end is provided with the A hydraulic fluid port in the pass, described A hydraulic fluid port is communicated to and closes the mould lower cover, close the A space between core rod axle and the pass mould cylinder barrel, be provided with the B hydraulic fluid port at an end that closes the mould loam cake, described B hydraulic fluid port is communicated to and closes the mould loam cake, close the B space between core rod axle and the pass mould cylinder barrel, it is characterized in that, in the mould cylinder barrel of described pass, also be provided with quick mandrel, described quick mandrel is fixed under the Guan Mo by connection cover and covers, described pass core rod axle sleeve is on quick mandrel, be provided with the C hydraulic fluid port on the core rod axle of described pass, described C hydraulic fluid port is communicated to the C space of closing between core rod axle and the quick mandrel.
The beneficial effects of the utility model are: the primary and secondary mould cylinder of injection machine of the present utility model is owing to increased quick mandrel in closing the mould cylinder barrel, when closing mould, use instead from the oil-feed of C hydraulic fluid port, and the C space is littler than A space, and under the situation that oil pump capacity is fixed, the filling time in C space is than A space much less, therefore, the Guan Mo action is fast, compares and adopts the outside machine that sub-cylinder body drives the master cylinder action that increases, and has reduced the volume and the manufacturing cost of machine.
Description of drawings
Fig. 1 is the structural representation of existing mould cylinder;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
See figures.1.and.2, the primary and secondary mould cylinder of injection machine, comprise and close mould lower cover 1, close mould loam cake 3, close mould cylinder barrel 2 and close core rod axle 4, mould lower cover 1 one ends are provided with A hydraulic fluid port 8 in the pass, A hydraulic fluid port 5 is communicated to and closes mould lower cover 1, close the A space 5 between core rod axle 3 and the pass mould cylinder barrel 2, be provided with B hydraulic fluid port 9 at an end that closes mould loam cake 3, B hydraulic fluid port 9 is communicated to and closes mould loam cake 3, close the B space 6 between core rod axle 2 and the pass mould cylinder barrel 4, in closing mould cylinder barrel 3, also be provided with quick mandrel 11, mandrel 11 is fixed on by connection cover 12 and closes on the mould lower cover 1 fast, closing core rod axle 4 is enclosed within on the quick mandrel 11, be provided with C hydraulic fluid port 10 on pass core rod axle 4, C hydraulic fluid port 10 is communicated to the C space 7 of closing between core rod axle 4 and the quick mandrel 11.
Operation principle of the present utility model is: when closing the mould action fast, and 10 oil-feeds of C hydraulic fluid port, A hydraulic fluid port 8 utilizes vacuum to pass through the prefill valve oil suction, 9 oil returns of B hydraulic fluid port, because C space 7 is less than A space 5, oil pump capacity is fixedly the time, 7 filling times of C space are short, and the action of closing core rod axle 4 is fast.When closing up, close the prefill valve deceleration and steadily close up mould, to A space 5, form the large tracts of land high pressure, finish locked mode from the 8 pressurization oilings of A hydraulic fluid port to mould is approaching.When carrying out the die sinking action, A hydraulic fluid port 8 is opened and is drawn valve by prefill valve oil return, 10 oil returns of C hydraulic fluid port, because B space 6 is little, quick die sinking action is finished by a large amount of oil returns of prefill valve in the A space.
