  However, in the conventional charging method, as shown in FIG. 9B, the alloy 2 does not fall out of the cup 1 when the semi-solid slurry-like alloy 2 is taken out, or as shown in FIG. 9C. In addition, when the semi-solid slurry-like alloy 2 is introduced from the pouring port located at the upper end of the sleeve 7, the alloy 2 is in an upright state without being rolled over along the sleeve 7. There is a problem that it is difficult to automate casting by a die casting machine because it is impossible to supply the injection mold 8 into each of the fixed mold 5 and the movable mold 4 without being charged. It was.

  Therefore, the present invention was created in view of the conventional circumstances as described above, and charging from the pouring port (feeding port) at the upper end side of the sleeve of the semi-solid slurry alloy is performed from the fixed mold side. The die casting machine can be molded by separating the dropping operation of the semi-solid slurry alloy from the semi-solid slurry forming cup and the charging operation of the alloy from the fixed mold side. It is an object of the present invention to provide a die casting alloy charging method and a charging device that can be surely automated.

In order to solve the above-described problem, in the method of charging a die-cast alloy according to the present invention, the fixed mold 5 and the movable mold 4 are brought into contact with each other, and then inserted into the sleeve 7 that is inserted into the fixed mold 5. The semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 is supplied, and the injection tip 8 slides in the sleeve 7 so that the inside of each of the fixed mold 5 and the movable mold 4 is provided. A method for charging a die-cast alloy in which a semi-solid slurry-like alloy 2 is mold-clamped into a shape corresponding to the shape, and before the movable mold 4 is abutted against the stationary mold 5, a semi-solid slurry forming cup The semi-solid slurry-like alloy 2 that can be taken out from 1 is inserted from the front end side of the sleeve 7 on the abutting surface side of the stationary mold 5 that abuts the movable mold 4.
In the die-casting apparatus according to the present invention for carrying out this die-casting method, each of the fixed mold 5 and the movable mold 4 that can be brought into contact with each other, and the fixed mold 5 are provided so as to penetrate each other. And a sleeve 7 in which an injection tip 8 is slidable. A semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 is supplied into the sleeve 7, and the inside of the sleeve 7 is injected into the sleeve 7. A die casting machine having a die casting machine in which a semi-solid slurry-like alloy 2 is mold-clamped into a shape corresponding to the internal shape of each of a fixed die 5 and a movable die 4 that are abutted against each other by slidingly moving 8. An alloy charging device, which is taken out from the semi-solid slurry forming cup 1 on the front end side of the sleeve 7 on the abutting surface side of the stationary mold 5 that abuts the movable mold 4. There as having a semi-solidified slurry inserting means for inserting the alloy 2 (10, 12, 14) which.
The insertion means (10, 12, 14) sandwich the semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 at a predetermined position, and insert the tip of the sleeve 7 on the abutting surface side of the fixed mold 5 The chuck mechanism unit 10 composed of a pair of clamping pieces that are opened and closed by an air cylinder so as to be inserted and removed from the side can be provided by an insertion / removal robot 12 provided at the tip of the robot arm 11.
The insertion / removal robot 12 is provided with a ladle 9 that supports the alloy 2 and puts the alloy 2 into the semi-solid slurry forming cup 1 on the opposite side of the robot arm 11 from the attachment portion of the chuck mechanism 10. It can be attached.
A receiving portion 13 that supports and inserts the semi-solid slurry-like alloy 2 can be provided on the front end side of the sleeve 7 on the abutting surface side of the fixed mold 5.
The receiving portion 13 can be supported by a cylindrical lifting means 14 that can be lifted and lowered on the distal end side of the sleeve 7.
The sleeve 7 can be made of a low-hardness material such as ceramic, casting, or copper alloy.
The sleeve 7 can be shortened by a length corresponding to a portion that does not need to be pushed in until the alloy 2 hits the movable mold 4, that is, a length corresponding to the pushing length.

In the die casting alloy charging method according to the present invention configured as described above, the semi-solid slurry-like alloy 2 that can be taken out from the semi-solid slurry forming cup 1 is fixed so as to abut against the movable mold 4. Inserted from the front end side of the sleeve 7 on the abutting surface side of the mold 5, the movable mold 4 is abutted against the fixed mold 5, and at the same time, the injection tip 8 slides in the forward direction in the sleeve 7. Alloy 2 is mold-clamped.
On the other hand, in the die casting alloy charging device according to the present invention, the insertion means (10, 12, 14) is in the mold open state before the movable mold 4 is abutted against the fixed mold 5, and the fixed mold 5 is inserted. The semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 is inserted into the end of the sleeve 7 on the abutting surface side.
The ladle 9 of the insertion / removal robot 12 supports the alloy 2 and puts the alloy 2 into the semi-solid slurry forming cup 1, and the chuck mechanism 10 is located at a predetermined position from the semi-solid slurry forming cup 1. The semi-solid slurry-like alloy 2 taken out is sandwiched and inserted into the abutting surface side of the fixed mold 5. Also, it is put into a predetermined position by a robot for taking out.
The cylinder type lifting / lowering means 14 causes the receiving portion 13 to rise and advance toward the tip end side of the sleeve 7, and then inserts the semi-solid slurry-like alloy 2 into the tip end side of the sleeve 7. The molds 4 and 5 are lowered and retracted downward.
The sleeve 7 formed of a low-hardness material such as ceramic, casting, or copper alloy makes it possible to impart lubricity to the injection tip 8 that slides.
The short sleeve 7 shortens the operating stroke of the injection tip 8 in response to the need to push the alloy 2 until it hits the movable mold 4.

  According to the present invention, the charging of the semi-solid slurry-like alloy 2 from the inlet (pouring port) at the upper end of the sleeve 7 is changed to charging from the fixed mold 5 side, and the semi-solid slurry-like alloy 2 By separating the dropping operation from the semi-solidified slurry forming cup 1 and the charging operation of the alloy 2 from the fixed mold 5 side, the molding by the die casting machine P can be surely automated.

  That is, this is because the die-casting alloy charging method according to the present invention allows the semi-solid slurry-like alloy to be taken out from the semi-solid slurry forming cup 1 before the movable die 4 is abutted against the stationary die 5. 2 is inserted from the front end side of the sleeve 7 on the abutting surface side of the fixed mold 5 that abuts the movable mold 4, whereby the injection stroke in the sleeve 7 can be shortened, and half It is possible to prevent the surface oxide film portion unique to the solidified slurry-like alloy 2 from entering the product. Further, since the temperature of the inside of the short sleeve 7 rises evenly, there is an advantage that the material of the sleeve 7 having a high hardness as in the prior art is unnecessary, and the semi-solid casting has not been put into practical use until now. The spread becomes possible, and the castability can be stabilized.

  On the other hand, in the casting apparatus for die-casting alloy according to the present invention, the semi-solid slurry forming cup 1 is taken out to the front end side of the sleeve 7 on the abutting surface side of the stationary mold 5 that abuts the movable mold 4. Since the insertion means (10, 12, 14) for inserting the semi-solid slurry-like alloy 2 is provided, the conventional semi-solid slurry-like alloy 2 is charged from the upper inlet (pour-in port) of the sleeve 7 side. Can be easily changed to the charging from the fixed mold 5 side, and the dropping operation of the semi-solid slurry-like alloy 2 from the semi-solid slurry forming cup 1 and the charging of the alloy 2 from the fixed mold 5 side can be performed. The operations can be easily separated from each other, and the molding by the die casting machine P can be surely automated.

  The insertion means (10, 12, 14) sandwich the semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 at a predetermined position, and insert the tip of the sleeve 7 on the abutting surface side of the fixed mold 5 Since the chuck mechanism portion 10 is composed of a pair of clamping pieces that are opened and closed by an air cylinder so as to be inserted and removed from the side, the insertion / removal robot 12 provided at the tip of the robot arm 11 is used. Without installing a transfer mechanism, the semi-solid slurry-like alloy 2 can be easily transported to the end of the sleeve 7 on the abutting surface side of the fixed die 5 of the die casting machine, thereby reducing the equipment cost. In addition, the installation space can be reduced. Moreover, since it can be input by either an insertion-only machine or an extraction-only machine, or by an insertion / extraction machine that is used for both operations, the convenience can be improved.

  The insertion / removal robot 12 is provided with a ladle 9 that supports the alloy 2 and puts the alloy 2 into the semi-solid slurry forming cup 1 on the opposite side of the robot arm 11 from the attachment portion of the chuck mechanism 10. Since it is attached, the work of receiving (receiving) and supporting the alloy 2, the work of putting the alloy 2 into the semi-solid slurry forming cup 1, and the semi-solid slurry-like alloy 2 are grasped and the fixed mold 5 is held. It is possible to easily construct an automated system for carrying the sleeve 7 toward the front end side of the sleeve 7 on the abutting surface side.

  A receiving portion 13 that supports and inserts the semi-solid slurry-like alloy 2 is provided on the front end side of the sleeve 7 on the abutting surface side of the fixed die 5, so that the semi-solid slurry-like alloy 2 is attached to the sleeve 7. It can be reliably inserted into the distal end side.

  Since the receiving portion 13 is supported by a cylinder lifting / lowering means 14 that can be moved up and down on the sleeve 7 distal end side, the semi-solid slurry-like alloy 2 is moved after the receiving portion 13 is moved up and advanced toward the sleeve 7 distal end side. The sleeve 7 can be easily inserted into the front end side of the sleeve 7, and after the alloy 2 is inserted, the receiving portion 13 is lowered and retracted to the lower side of the two molds 4 and 5, thereby joining the two molds 4 and 5 together. On the other hand, the mold clamping operation can be easily performed without any obstacle.

  Since the sleeve 7 is formed of a low-hardness material such as ceramic, casting, or copper alloy, it can provide lubricity to the injection tip 8 that slides. That is, while the conventional sleeve 7 material is a hardened member, the impact of heat is reduced. Therefore, the sleeve 7 can be made of ceramic, casting, copper alloy, etc., thereby providing lubricity. It becomes possible to improve.

  Since the sleeve 7 is shortened by a length corresponding to a portion that does not need to be pushed until the alloy 2 hits the movable mold 4, the operation stroke of the injection tip 8 can be shortened.

The present invention is not limited to the structure / shape indicated by the reference numeral.

  The best mode for carrying out the present invention will be described below with reference to the drawings. The symbol P shown in the drawing represents a semi-solid slurry of a meltable alloy such as an aluminum alloy in a semi-solid forming apparatus (not shown). 2 is a die casting machine for casting the alloy 2 after it is made into a shaped alloy 2. As shown in FIGS. 1 and 2, the die casting machine P is disposed so as to penetrate the fixed mold 5 and the fixed metal mold 5 and the movable mold 4 that can be brought into contact with each other. The injection tip 8 is configured to include a sleeve 7 that is slidable in the front-rear direction.

  Further, the semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 is supplied into the sleeve 7, and the injection tip 8 slides in the sleeve 7, so that the fixed metal abutted against each other. The semi-solid slurry-like alloy 2 is mold-clamped in a form corresponding to the internal shape of each of the mold 5 and the movable mold 4.

  The fixed mold 5 is integrated by a fixed die plate 6, and a sleeve 7 is disposed so as to penetrate from the rear end face side of the fixed die plate 6 to the front end face of the fixed mold 5, and injection is performed inside the sleeve 7. The chip 8 can slide. The sleeve 7 is formed in a tubular shape by a relatively low hardness material such as ceramic, casting, or copper alloy, and has a length corresponding to a portion that does not need to be pushed in until the alloy 2 hits the movable mold 4. The operation stroke of the injection tip 8 can be shortened by making it short, that is, a length corresponding to the length to be pushed in.

  The movable mold 4 is integrated by the movable die plate 3 and can be moved to a position where it abuts against the abutting surface of the fixed mold 5 by a driving means (not shown). Further, a projecting pressing mold 4A for mold clamping is projected on the abutting surface side of the movable mold 4, and when the molds 4, 5 are abutted against each other, The protruding pressing mold 4 </ b> A is fitted to the front end side of the sleeve 7 on the abutting surface of the fixed mold 5.

  Also, an insertion means for inserting the semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 into the sleeve 7 front end side on the abutment surface side of the fixed mold 5 that abuts the movable mold 4. (10, 12, 14). As a specific example of the insertion means (10, 12, 14), an insertion / removal robot 12 is used as shown in FIG. In other words, the insertion / removal robot 12 has a chuck mechanism portion 10 formed of a pair of clamping pieces that are driven to open and close by an air cylinder at the tip of the robot arm 11. In addition, in order to draw up the alloy 2 and put the alloy 2 into the semi-solid slurry forming cup 1 at a position on the opposite end side of the chuck mechanism 10 on the same tip side of the robot arm 11. The ladle 9 is provided.

  The ladle 9 is made of a heat-resistant cup 1 having a volume capable of accommodating a predetermined amount of alloy 2 therein, and the outer wall near the opening of the cup 1 is connected to one end of the rotation axis at the tip of the robot arm 11. It is installed in a state where it joins. Therefore, when the rotating shaft rotates in a horizontal state, the opening of the ladle 9 can also rotate around the rotating shaft, and for this reason, a semi-solid slurry state formed by a semi-solid molding machine (not shown). When the alloy 2 is received (received) and the ladle 9 supporting the alloy 2 rotates, the alloy 2 in the ladle 9 can be discharged.

  The chuck hand mechanism has an attachment piece of a predetermined length having one end attached to the rotating shaft and a clamping portion on the other end. The sandwiching portion includes a pair of first sandwiching piece and second sandwiching piece, and the first sandwiching piece and the second sandwiching piece are provided in a direction perpendicular to the longitudinal direction of the mounting piece, Among these, the substantially center position of one clamping piece is being fixed to the other end side of the attachment piece. And this clamping part can open and close a pair of 1st clamping piece and 2nd clamping piece with the air cylinder driven with the compressed air supplied from the piping laid along the robot arm 11 Thus, the semi-solid slurry-like alloy 2 can be sandwiched.

  The insertion / removal robot 12 has a multi-axis joint structure, and a plurality of arms are sequentially connected to a base installed on the installation surface, and each arm is bent and bent by the axial joint of the connection portion. By performing each operation such as rotation, the wrist can be controlled to move three-dimensionally within a predetermined range. Further, instead of using such an insertion / removal robot 12, the chuck mechanism unit 10 of a dedicated loading machine may be used. In addition, it is also possible to input either by an insertion-only machine or an extraction-only machine, or by an insertion / extraction machine that combines both operations.

  Further, as shown in FIG. 3, a semi-solid slurry-like alloy 2 is supported on the lower edge portion of the sleeve 7 tip opening on the abutting surface side of the fixed mold 5 from the sleeve 7 tip opening to the inside of the sleeve 7. Alternatively, a dedicated mold 15 provided with a substantially semi-cylindrical receiving portion 13 that can be inserted into the housing may be used. At this time, when the molds 4 and 5 are abutted against each other, the receiving portion 13 is placed below the projecting pushing mold 4A on the abutting surface side of the movable mold 4 so that the receiving part 13 does not strike the movable mold 4. Is formed with a recessed portion to which the receiving portion 13 can be inserted.

  Further, as shown in FIG. 4, the receiving portion 13 may be supported by a cylinder lifting / lowering means 14 that can be lifted / lowered on the distal end side of the sleeve 7 on the abutting surface side of the fixed mold 5. That is, in the cylinder type lifting means 14, the piston rod is driven up and down by compressed air by an air cylinder, and the receiving portion 13 is attached to the upper end of the piston rod. The air cylinder itself is disposed on the lower side of the abutting surface of the fixed mold 5, and the position where the receiving portion 13 faces the lower edge of the sleeve 7 distal end and the position where the air cylinder retracts to the lower side of the fixed mold 5. It can be moved freely between.

  Thus, when the semi-solid slurry-like alloy 2 is inserted into the tip end of the sleeve 7 of the fixed mold 5, it is directly inserted into the fixed mold 5 by the chuck mechanism 10 of the above-described insertion / removal robot 12. Depending on conditions such as the shapes of the molds 4 and 5 and the size of the alloy 2, the dedicated mold 15 having the receiving portion 13 may be used to receive the alloy 2 in the fixed mold 5, or the cylinder type lifting / lowering means 14 It is possible to insert the alloy 2 into the tip end of the sleeve 7 using the receiving portion 13 using the.

  Next, an example of use and operation of the best mode configured as described above will be described. As shown in FIG. 6, a meltable molten alloy such as an aluminum alloy is formed by a semi-solid forming apparatus (not shown). After the alloy 2 is formed, the alloy 2 is supported by the ladle 9 of the insertion / removal robot 12, and the alloy 2 is put into the semi-solid slurry forming cup 1. Then, the semi-solid slurry forming cup 1 is grasped by the chuck mechanism 10 of the insertion / removal robot 12 and then transported to the designated position, and the cup 1 is inverted to drop the semi-solid slurry alloy 2 (step 1). ).

  The semi-solid slurry-like alloy 2 taken out from the semi-solid slurry forming cup 1 is gripped by the chuck mechanism 10 of the insertion / removal robot 12 as the insertion means (10, 12, 14) (step 2). The slurry taken out by the chuck mechanism unit 10 enters the fixed die 5 when the movable die 4 and the fixed die 5 are fully opened, and the chuck mechanism unit 10 enters the fixed die 5. The semi-solid slurry-like alloy 2 is inserted into the tip end of the sleeve 7 of the fixed mold 5 (step 3).

  When the insertion is completed, the movable die plate 3 moves closer to the fixed die plate 6 to tighten both the molds 4 and 5, and the movable mold 4 pushes the semi-solid slurry alloy 2 into the sleeve 7 to complete the loading. (Step 4).

  When both molds 4 and 5 are tightened, the injection tip 8 moves forward in the sleeve 7 and the semi-solid slurry-like alloy 2 is pressed from the rear side by the injection tip 8 so that the fixed die 5 abutted against each other. Then, the semi-solid slurry-like alloy 2 is mold-clamped in a form corresponding to the internal shape of each movable mold 4 to complete the casting (step 5).

  Thus, the insertion means (10, 12, 14) of the present invention once removes the semi-solid slurry-like alloy 2 from the semi-solid slurry forming cup 1 and securely removes it from the chuck mechanism of the insertion / removal robot 12. The semi-solid slurry-like alloy 2 is directly inserted into the sleeve 7 from the tip end of the sleeve 7 of the fixed mold 5 after being gripped by the portion 10, so that the molding can be surely performed.
