The mold 5 includes a lower mold 6 fixed on the base 4, two side molds 71 slidably mounted on the lower mold 6 in the left-right direction, and a paper surface on the lower mold 6. It is composed of two side molds 72 (only one is shown in the figure) slidably mounted in an orthogonal direction, and an upper mold 8 that can be raised and lowered. These lower mold 6, side mold 71, side mold 72 and a cavity 9 is formed between the upper mold 8.

As shown in FIG. 2, four gates 10 are opened on the cavity forming surface a of the lower mold 6, and the stalk 12 communicates with the runner 11 from which each gate 10 is derived via the sprue 13. ing.
Each gate 10 is formed in a drum shape, and a wire mesh screen 14 is disposed in an upper hole 10a formed in an inverted frustoconical shape.

As shown in FIGS. 3 and 4, each wire mesh screen 14 is formed in a substantially frustoconical shape, and includes an arc-shaped peripheral wall portion 15 that rises in a curved manner, and an end wall portion 16 that exists on the small-diameter end side of the arc-shaped peripheral wall portion 15. The large diameter end side of the arc-shaped peripheral wall portion 15 is opened. The end wall portion 16 includes an annular outer peripheral portion 17 and a small frustoconical convex portion 18 that continues to the annular outer peripheral portion 17 and protrudes toward the large-diameter end side. The outer diameter d1 at the large diameter end of the arc-shaped peripheral wall portion 15 is set larger than the inner diameter d2 (see FIG. 8A) at the large diameter end of the upper hole 10a.
Each wire mesh screen 14 is made by pressing a wire mesh made of a magnetic material attracted by a magnet. The wire mesh that is the material of the wire mesh screen 14 is composed of a plurality of copper wires and a plurality of steel wires in the form of a plain woven fabric.

5 to 7 show a wire mesh mounting device 20 for setting the mounted wire mesh screen 14 by pushing it into the upper hole 10a of the gate 10 of the mold 5. FIG.
As shown in FIG. 5, the wire netting device 20 includes a cylindrical body 21. The cylindrical body 21 is a cylindrical member that is formed of a nonmagnetic material such as an aluminum material and has a hollow portion 22 therein. The cylindrical body 21 is formed by integrally forming a bottom wall 23 and a peripheral wall 24. The bottom wall 23 is formed thinner than the peripheral wall 24, and a concave portion 25 is formed toward the inside. Here, the concave portion 25 is formed so as to be able to receive the small frustoconical convex portion 18 of the wire mesh screen 14.

  At the other end of the cylindrical body 21, a female thread portion 30 is formed at the inner periphery of the opening, and a lid 31 made of an aluminum material is screwed and fixed thereto. The lid 31 has a flange portion 32 formed with a boss portion 33 to be inserted into the cylindrical body 21, and a male screw portion 34 is formed on the outer periphery of the boss portion 33. It is fastened and fixed to the female screw portion 30 on the inner periphery of the opening. A grip portion 35 made of a steel material formed in an L shape is screwed and fixed to the flange portion 32 of the lid 31.

  Here, an air vent hole 36 is formed in the lid 31 to communicate the cavity portion 22 with the outside. Further, a retaining screw 37 is in contact with the boss 33 and screwed to the peripheral wall 24 of the cylindrical body 21. The air vent hole 36 ensures the circulation of the internal air in the cavity 22 by the movement of a magnet 41 described later.

The grip portion 35 includes a tip portion 38 that is bent at a right angle. A screw portion 39 that is screwed into the central portion of the flange portion 32 of the lid 31 is formed on the tip portion 38. The distal end portion 38 is screwed in until the hollow portion 22 in the lid 31 protrudes toward the bottom wall 23 side, and a lock nut 40 that is screwed into the distal end portion 38 is tightened from the outer surface side of the lid 31 so that the grip portion 35 is secured to the lid 31. It is fixed to.
Therefore, when the tip end portion 38 of the grip portion 35 adjusts the amount of protrusion into the cavity portion 22 by changing the tightening position of the lock nut 40, and the magnet 41 moves to the lid 31 side, the outer surface of the bottom wall 23. The influence of the attracting force of the magnet 41 can be adjusted.

A magnet 41 is accommodated in the hollow portion 22 between the bottom wall 23 and the lid 31. As shown in FIG. 7, the magnet 41 is accommodated so as to be able to reciprocate only by inclining the bottom wall 23 side of the cylindrical body 21 or by tilting the lid 31 side up, and the magnet 41 is a stroke end on the lid 31 side. In this case, the contact portion 35 is restricted by being brought into contact with the tip portion 38 of the grip portion 35. Here, a gap is provided between the magnet 41 and the inner surface of the peripheral wall 24 of the cylindrical body 21, and the bottom wall 23 and the lid 31 side are moved by the movement of the magnet 41 inside the cylindrical body 21 together with the air vent hole 36 of the lid 31. A vacuum is applied so that the movement of the magnet 41 is not hindered.
When the magnet 41 is positioned at the stroke end on the bottom wall 23 side with the bottom wall 23 side down, the attracting force of the magnet 41 reaches the outer surface of the bottom wall 23 and the wire mesh screen 14 fragment on the outer surface of the bottom wall 23. 14 'can be attracted and held on the outer surface of the bottom wall 23, and when the magnet 41 is positioned at the stroke end on the lid 31 side with the lid 31 side down, the end surface and bottom of the magnet 41 on the bottom wall 23 side A clearance CL is provided between the inner surface of the wall 23 and the outer surface of the bottom wall 23 is set to be outside the influence range of the attractive force of the magnet 41 or to be less affected. Therefore, the clearance CL can be adjusted by the screwing amount of the tip portion 38 of the grip portion 35 into the lid 31.

  That is, when the magnet 41 is located at the stroke end on the lid 31 side, the gap CL is spaced from the outer surface of the bottom wall 23 and the magnet 41 so that the outer surface of the bottom wall 23 is When the air is blown to the outer surface of the bottom wall 23 by the nozzle 43 of the air blow 42 in this state, the size of the wire mesh screen 14 adhered to the outer surface of the bottom wall 23 is set. 'Can be blown away and removed.

  Here, when the magnet 41 is positioned at the stroke end on the bottom wall 23 side, the magnet 41 is pushed into the gate 10 while holding the wire mesh screen 14 on the bottom wall 23, but the wire mesh screen 14 is In the state of being pushed into 10, it is locked to the gate 10 by its own elastic force, and when the wire netting device 20 is pulled up, it will overcome the attractive force of the magnet 41 and remain in the gate 10. .

Next, the operation of the embodiment will be described.
When a robot or an operator grips the grip portion 35 of the wire netting device 20 and turns the bottom wall 23 downward as shown in FIG. 5, the magnet 41 moves to the bottom wall 23 side. Thereby, the attractive force of the magnet 41 reaches the outer surface of the bottom wall 23. In this state, the wire mesh mounting device 20 is moved to a place where a set container (not shown) of the wire mesh screen 14 (not shown) is installed, and the bottom of the wire mesh mounting device 20 is placed on the uppermost metal mesh screen 14 loaded on the set container. When the wall 23 is pressed, the concave portion 25 of the bottom wall 23 of the wire mesh mounting device 20 receives the small truncated cone shaped convex portion 18 of the wire mesh screen 14, and the top portion of the small truncated cone shaped convex portion 18 is attracted to the bottom wall 23 by the magnet 41. The wire mesh screen 14 is held by the wire mesh mounting device 20.

Then, the wire netting device 20 is moved above the gate 10 of the lower mold 6 of the low-pressure casting device 1 (FIG. 8A), and as shown in FIG. The wire mesh screen 14 held on the bottom wall 23 is inserted into the upper hole 10a of the gate 10 of the lower die 6 of the low-pressure casting apparatus 1, and the large diameter end side of the arc-shaped peripheral wall portion 15 of the wire mesh screen 14 is the tapered inner periphery of the upper hole 10a. The metal screen 14 is forcibly pushed into the upper hole 10a while being bent by the surface.
Then, the large diameter end of the arc-shaped peripheral wall portion 15 of the wire mesh screen 14 is elastically locked in the gate 10, and the wire mesh screen 14 is set on the gate 10. In this state, the wire mesh screen 14 is held by the gate 10 by its own elastic force.

  Then, as shown in FIG. 8C, when the wire mesh mounting device 20 is pulled out, the peripheral edge b of the arc-shaped peripheral wall portion 15 of the wire mesh screen 14 is crimped and locked to the inner peripheral surface of the upper hole 10a by its own elastic force. Therefore, the wire mesh screen 14 is set in the upper hole 10 a of the gate 10 of the lower die 6 of the low pressure casting apparatus 1 against the attracting force of the magnet 41.

Then, as shown in FIG. 7, when the lifted wire mesh mounting device 20 is tilted so that the bottom wall 23 is on the upper side, the magnet 41 accommodated in the cavity portion 22 strokes toward the lid 31 and the grip portion Stops in contact with the tip 38 of 35. At this time, even if the piece 14 ′ of the wire mesh screen 14 remains on the bottom wall, the magnet 41 moves to the stroke end on the lid 31 side, and the attracting force does not reach the outer surface of the bottom wall 23. Since the impact at the time of abutment against the tip end portion 38 of the gripping portion 35 acts at the stroke end on the lid 31 side, the fragment 14 ′ is peeled off from the outer surface of the bottom wall 23 and moved downward, and this is moved to the nozzle of the air blow 42. It can be easily removed by blowing away with 43.
When the cleaning of the wire mesh mounting device 20 is completed, the wire mesh mounting device 20 receives the next wire mesh screen 14, and the above-described operation is repeated.

  When the wire mesh screen is set in the gate 10 of the mold 5 as described above, the mold 8 is clamped and gas is applied to the surface of the molten metal 44 heated and held in the crucible 2 as shown in FIG. By applying pressure, the molten metal 44 is raised in the stalk 12 and fed through the sprue 13, the runner 11, and each gate 10 to supply the molten metal to the cavity 9. Then, impurities such as oxides in the molten metal 30 are collected by each wire mesh screen 14.

  According to the above embodiment, the magnet 41 is stroked toward the bottom wall 23, the small frustoconical convex portion 18 of the wire mesh screen 14 is received in the recess 25 of the bottom wall 23, and the wire mesh screen 14 is applied to the bottom wall 23 by the magnetic force of the magnet 41. The bottom wall 23 is pushed into the gate 10 of the mold 8, and the metal screen 14 adsorbed on the bottom wall 23 is locked and set in the gate 10 of the mold 5 by elastic force. Thereafter, leaving the wire mesh screen 14 in the mold 5, the wire mesh mounting device 20 is separated from the gate 10, the cylinder 21 is tilted to move the magnet 41 away from the bottom wall 23, and the wire mesh screen 14 adhered to the outer surface of the lid 31. The fragments 14 ′ and the like can be cleaned by the nozzle 43 of the air blow 42.

  Therefore, when the wire mesh screen 14 is set, the wire mesh screen 14 is adsorbed through the bottom wall 23 made of an aluminum material that is not adsorbed by the magnet 41, so that the gate can be easily separated from the magnet 41 only by the elastic force of the wire mesh screen 14. Accordingly, the problem that the wire mesh mounting device 1 cannot attach the wire mesh screen 14 to the gate 10 of the mold 5 and returns while remaining on the bottom wall 23 can be eliminated.

Further, even if a piece 14 ′ or the like of the wire mesh screen 14 remains in the wire mesh mounting device 1 after the wire mesh screen 14 is set in the mold 5, it is not affected by the attracting force of the magnet 41 or is not affected. Since it can remain on the outer surface of the bottom wall 23, it can be easily removed by the nozzle 43 of the air blow 42 reliably.
Then, when the cylinder 21 is tilted and the magnet 41 moves to the lid 31 side and comes into contact with the distal end portion 38 of the grip portion 35, the fragments 14 ′ and the like attached to the outer surface of the bottom wall 23 are removed from the bottom wall 23. Since it can be peeled off and dropped to the lower side of the bottom wall 23, even the stuck piece 14 ′ can be easily removed away from the bottom wall 23 by the nozzle 43 of the air blow 42.
Here, the magnet 41 that has come into contact with the tip portion 38 of the grip portion 35 is attracted to the tip portion 38 of the grip portion 35 that is a steel material. The magnet 41 is attracted to the tip portion 38, and this attracting force is such that the magnet 41 can be easily separated from the bottom wall 41 when the bottom wall 23 is directed downward.

  Then, each movement of a series of processes for mounting and cleaning the metal mesh screen 14 by the metal mesh mounting device 20 is not wasteful, and the work can be performed with a small number of processes by using the elastic force of the metal mesh screen 14 itself. That is, by lowering the wire mesh mounting device 20, the wire mesh screen 14 is pushed into the gate 10 of the mold 5, and by lifting the wire mesh mounting device 20, the wire mesh screen 14 is mounted on the mold 5. By simply tilting the bottom wall 23 upward, the piece 14 ′ of the wire mesh screen 14 attached to the bottom wall 23 can be dropped below the outer surface of the bottom wall 23. Can be installed.

In addition, since the magnet 41 is brought into contact with the distal end portion 38 of the gripping portion 35, the piece 14 ′ of the wire mesh screen 14 attached to the bottom wall 23 can be released from the attached state to the bottom wall 23. In a further cleaning operation, it becomes easy to remove the pieces 14 'and the like of the wire mesh screen 14, and the product quality can be improved.
And since the fragment | piece 14 'of the metal-mesh screen 14 adhering to the bottom wall 23 with air using the nozzle 43 of the air blow 42 which is the existing equipment can be removed easily, the cleaning operation of the metal-mesh mounting device 20 is easy to perform.

  In addition, this invention is not restricted to embodiment mentioned above, For example, although the air blow 42 was demonstrated as an example as a cleaning means, a brush and a marking hair can also be used.
