Description
Technical field
The utility model relates to the oil channel structures on a kind of injection forming machine, is specially the oil channel structures being synchronized to mode locking cylinder supercharging by injection piston power.
Background technology
The Jet forming machine oil circuit of current all-hydraulic locked mode all adopts first supercharging that clamping mechanism is locked, and then carries out the oil circuit of injection.There is a lot of drawback in this oil circuit: first, and in advance, pressurization time is elongated in supercharging, easily produces oil pressure and reveal, cause easily rising during injection mould; Secondly, make existing Jet forming machine add a pressurizing action, cause the molding time cycle elongated; Again, supercharging in advance, prevents oil pressure from revealing therefore required hydraulic part precision prescribed is high again, and manufacture difficulty is large, also invisiblely improves manufacturing cost.Above-mentioned disadvantage, constrains the Jet forming machine promotion and application of all-hydraulic clamping mechanism greatly.
Utility model content
For problems of the prior art, the purpose of this utility model is to provide the oil channel structures being synchronized to mode locking cylinder supercharging by injection piston power, can solve the problems of the technologies described above.
Above-mentioned purpose is achieved through the following technical solutions:
The oil channel structures of mode locking cylinder supercharging is synchronized to by injection piston power, include locked mode parts and penetrate platform parts, described locked mode parts comprise mode locking cylinder and Mode-Locking Cavity, described platform parts of penetrating include injection cylinder, injection piston, supercharging oil pocket and injection chamber, it is characterized in that: between described supercharging oil pocket and Mode-Locking Cavity, be provided with asphalt channel, asphalt channel is provided with check valve, utilize injection piston power by asphalt channel and check valve, the oil of supercharging oil pocket is pushed in Mode-Locking Cavity, realizes synchronous supercharging.
Adopt above-mentioned oil channel structures, tool has the following advantages:
1, be synchronized to mode locking cylinder supercharging with injection piston-advance power simultaneously, change the existing step needing supercharging in advance;
2, obviously can save the time of a pressurizing action, thus shorten the cycle of ejection formation;
3, not only reduce pressurization time, and pressurization time is just synchronous with injection, namely during injection, cavity pressure is larger, and boost pressure is also higher.Thus avoid completely because of pressurization time long generation pressure release and injection pressure larger, the mould phenomenon that rises of the relatively lower generation of boost pressure;
4, the hydraulic part needed for pressurizing action, only requires general precision thus can lower manufacturing cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is oil channel structures schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the oil channel structures of mode locking cylinder supercharging is synchronized to by injection piston power, include locked mode parts 1 and penetrate platform parts 2, described locked mode parts 1 comprise mode locking cylinder 11 and Mode-Locking Cavity 12, described platform parts 2 of penetrating include injection cylinder 21, injection piston 22, supercharging oil pocket 23 and injection chamber 24, asphalt channel 3 is provided with between supercharging oil pocket 23 and Mode-Locking Cavity 12, asphalt channel 3 is provided with check valve 31, and the oil of the powered supercharging oil pocket 23 that injection piston 22 advances synchronously pushes to realizing synchronous supercharging in Mode-Locking Cavity.
As shown in Figure 2, fundamental diagram of the present utility model, while oil pump 4 is energized work, S3 is energized, and makes oil pump 4 normal pressure pressure oil (below 175 kg/cm) enter Mode-Locking Cavity 12 by V3 valve P B3 chamber.When Mode-Locking Cavity 12 pressure reaches setting value, S3 power-off, S1 is energized, oil pump 4 normal pressure pressure oil is made to enter injection chamber 24 by V1 valve P A1, thus while promoting the reach of injection piston 22, supercharging oil pocket 23 pressure is forced to raise, until when being elevated to the normal pressure pressure being greater than Mode-Locking Cavity 12 setting, open check valve 31 and enter Mode-Locking Cavity 12, force locked mode die cavity 12 to be progressively increased to required high-pressure (below 300 kg/cm) from the pressure of setting normal pressure along with injection piston 22 moves forward, thus realize injection synchronization gain high-voltage lock mould power.At the end of injection, S1 power-off, S5 is energized, and the P A chamber of oil pump 4 pressure oil passage V2 valve enters melten gel motor 5, and the propulsive thrust of plastics when driving screw rod to rotate, move on to origin position after impelling injection piston 22.Oil pump oil return simultaneously enters supercharging oil pocket 23 through the T B of V2 valve, for the storage of pressurised oil is carried out in next circulation.Thus realize injection repeatedly successively, and have to the function of the synchronous supercharging of mode locking cylinder 11.
