In the utility model, the material absorbing and pushing are directly completed in the upward and downward movement of the valve on the piston of the cylinder, the feeding speed and the working efficiency are improved, by adopting the structure, the defects of material clamping and leaking caused by a screw device are avoided, the material amount injected into the mold each time can be effectively ensured, the pressing quality is improved, and the structure is more compact.
Description
Technical field
The utility model relates to a kind of magnetic material wet type forming hydraulic press and inhales discharging device, contain top board, pillar, material cylinder, mould and charging basket, this top board is fixed on material cylinder top by pillar, be connected with the center oil cylinder between the piston of material cylinder and the top board, the lower surface of this material cylinder has charging aperture and the discharging opening that is connected with charging basket, mould side by side.
Background technology
Traditional magnetic material wet type forming hydraulic press is inhaled the moving blowing amount of inhaling of material cylinder of discharging device and is controlled inaccurate, it is serious to leak material, sometimes also must increase external force and carry out suction, usually adopt at material cylinder charging aperture and install screw feeder, material sucking valve, baiting valve device additional, long-time use easily gets stuck, leaks material, can't accurately control the inventory that is injected into mould, and the product quality that causes suppressing is difficult to guarantee, and material feeding is time-consuming, and production efficiency is low.
The utility model content
The technical problems to be solved in the utility model provide a kind of material feeding accurately and the magnetic material wet type forming hydraulic press of compact conformation inhale discharging device.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of magnetic material wet type forming hydraulic press is inhaled discharging device, contain top board, pillar, material cylinder, mould and charging basket, described top board is fixed on material cylinder top by pillar, be connected with the center oil cylinder between the piston of described material cylinder and the top board, the lower surface of described material cylinder has the charging aperture and the discharging opening of charging basket, mould connection side by side, it is characterized in that: be connected with the material valve between described material cylinder and charging basket, mould, described material valve is fixed on material cylinder side by installing rack.
Further, the pumping board of described material valve and is fixed on the installing rack by valve seat between charging and discharging mouth and charging basket, mould, has into blowing through hole on the described pumping board, and two ends are connected with unidirectional plunger piston fluid pressure cylinder respectively.
Advantage of the present utility model is: promote pumping board by unidirectional plunger piston fluid pressure cylinder, pumping board advance blowing through hole and charging aperture conducting, seal discharging opening simultaneously, move on the center oil cylinder pulling material cylinder piston, utilize pressure differential that material is sucked, close charging aperture by the unidirectional plunger piston fluid pressure cylinder of the other end again, the conducting discharging opening, material cylinder piston pushes connected mould with material.Directly finish absorption, the release of material in the process of on material cylinder piston, moving, moving down, material feeding speed and operating efficiency have been improved, adopt this structure, avoided using that the screw feeder device causes gets stuck, leaks shortcoming such as material, make that the inventory of each injection mould is effectively guaranteed, reached stable uniformity, it is compact more to have improved compacting quality and structure.
Description of drawings
Fig. 1 is that a kind of magnetic material wet type forming hydraulic press of the present utility model is inhaled the discharging device structural representation.
Fig. 2 is the vertical view that a kind of magnetic material wet type forming hydraulic press of the present utility model is inhaled discharging device.
The specific embodiment
As shown in Figure 1, 2, comprise top board 2, pillar 3, material cylinder 1, center oil cylinder 4, piston rod 9, charging aperture 5, discharging opening 6, charging basket 7, mould 8, material valve 10, installing rack 11, material valve 10 comprises pumping board 12, valve seat 13, unidirectional plunger piston fluid pressure cylinder 14,15.
Above-mentioned top board 2 is fixed on material cylinder 1 top by pillar 3, the piston of material cylinder 1 is as the cylinder body of center oil cylinder 4, the piston rod 9 of this center oil cylinder 4 is connected with top board 2, utilizes the upper and lower cavity pressure differential in the cylinder to promote the cylinder body of center oil cylinder 4 and expect that the piston of cylinder 1 moves.The lower surface of material cylinder 1 has charging aperture 5 and discharging opening 6, and wherein, charging aperture 5 is connected with charging basket 7, and discharging opening 6 is connected with mould 8.
For realizing the automatic suction blowing of material cylinder, we are expecting to be connected with material valve 10 between cylinder 1 and charging basket 7, the mould 8, and will expect that by installing rack 11 valve 10 is fixed on material cylinder 1 side.Its concrete structure is: as shown in Figure 2, the pumping board 12 of material valve 10 is between charging and discharging mouth 5,6 and charging basket 7, mould 8, and be fixed on the installing rack 11 by valve seat 13, have one and advance blowing through hole 16 on pumping board 12, two ends are connected with the unidirectional plunger piston fluid pressure cylinder 14,15 that promotes pumping board 12 respectively.
During use, the unidirectional plunger piston fluid pressure cylinder 14 of A end promotes pumping board 12 to be stopped behind certain position, makes that the blowing through hole 16 that advances on the pumping board 12 overlaps with charging aperture 5, and the sealing discharging opening.Then, center oil cylinder 4 promptly expects to move on the piston of cylinder 1, makes material cylinder 1 internal pressure step-down, under the effect of atmospheric pressure the material charging basket 7 in is sucked and expects in the cylinder 1, sealed by pumping board 12 owing to be access to the discharging opening 5 of mould 8, temporarily be kept in the material cylinder 1 so suck the material of material cylinder 1; After suction is finished, the unidirectional plunger piston fluid pressure cylinder 15 of B end is started working, the unidirectional plunger piston fluid pressure cylinder 14 that promotes pumping board 12 and A end moves to the A direction, make the blowing through hole 16 that advances on the pumping board 12 overlap with the discharging opening 5 that is connected mould 8, the cylinder body of center oil cylinder 4 moves down then, make the pressure of material cylinder 1 inside increase, material in the material cylinder 1 is pressed into mould 8, thereby realized automatic suction blowing, directly finish absorption, the release of material in the process of on material cylinder piston 9, moving, moving down, feasible material feeding speed to mould 8 is improved, and has improved operating efficiency.Adopt this structure, the free gap of the pumping board 12 of material valve 10 has realized transferring to the best, and reconditioning is convenient behind the sealing surface wear, effectively raises service life.
