Two second barrier portions are provided corresponding to a total of two die-cast product portions.

Hereinafter, based on the description, the overflow part 16, the overflow part 17, the overflow part 18, and the die-cast product part 15 are separated from the die-casting integrated body 10, and are described more specifically. The runner portion 12 of the die-casting integrated body 10 is grasped by the chuck 40 and taken out from the mold 30, and is sequentially shifted to the first position P1 to the fourth position P4. The direction from the mold 30 to the first position P1 is horizontal, the direction from the first position P1 to the second position P2 is vertical, the direction from the second position P2 to the third position P3 is horizontal, and from the third The direction of the position P3 toward the fourth position P4 is a vertical direction.

As can be seen from FIG. 7 to FIG. 10, in the process of the die-casting integrated body 10 from the first position P1 to the second position P2, all of the overflow portion 16, the overflow portion 17, and the overflow portion 18 are removed from the die-casting integrated body 10. Remove. When the die-cast integrated body 10 is in the first position P1, neither of the overflow portion 16, the overflow portion 17, or the overflow portion 18 is dropped (see FIG. 7). When the die-cast integrated body 10 moves upward in the vertical direction toward the second position P2, first, the intermediate overflow portion 16 contacts the first obstacle portion 26, and the gate portion 14 is bent and dropped (see FIG. 8). When the die-cast integrated body 10 moves further upward in the vertical direction toward the second position P2, the second end overflow portion 18 contacts the first obstacle portion 28, and the gate portion 14 is bent and dropped (see FIG. 9). When the die-cast integrated body 10 moves further upward in the vertical direction toward the second position P2, the first end overflow portion 17 contacts the first obstacle portion 27, and the gate portion 14 is bent and dropped (see FIG. 10).

After all the overflow part 16, the overflow part 17, and the overflow part 18 are removed from the die-casting integrated body 10, the die-casting integrated body 10 moves from the second position P2 to the third position in the horizontal direction. At position P3, the die-casting integrated body 10 is moved from the third position P3 upward in the vertical direction to the fourth position P4. The reason why the die-casting integrated product 10 is moved from the second position P2 to the third position P3 is to arrange the die-cast product part 15 directly below the second obstacle part 25. The movement of the die-casting integrated product 10 from the third position P3 to the fourth position P4 is performed in order to remove the die-casting product part 15 from the die-casting integrated product 10.

It is not necessarily limited to this, and in some cases, the movement of the die-casting integrated body 10 from the second position P2 to the third position P3 is to move the die-casting integrated body 10 in the direction of taking out the die-casting integrated body 10 from the mold 30, It is performed after moving the separate die-casting integrated body 10 for the overflow part 16, the overflow part 17, and the overflow part 18, and before moving the separate die-casting integrated body 10 for the die-cast product part 15. It is assumed that the second obstacle portion 25 is positioned above the first obstacle portion 26, the first obstacle portion 27, and the first obstacle portion 28 in the vertical direction.

When the die-cast integrated body 10 is in the third position P3 (see FIG. 11), the die-cast product part 15 is still coupled to the flow path part 13. When the die-casting integrated product 10 moves upward in the vertical direction from the third position P3 toward the fourth position P4, the die-casting product portion 15 contacts the second obstacle portion 25 and drops (see FIG. 12).

Moving direction of the separated die-casting integrated body 10 for the overflow portion 16, the overflow portion 17, and the overflowing portion 18 and / or moving direction of the separated die-casting integrated body 10 for the separated die-casting product portion 15 and the die-casting integrated body 10 The removal direction from the mold 30 is different. It is facilitated to set the jig 20 as a stationary member or a fixed member.

Moving direction of the separated die-casting integrated body 10 for the die-cast product part 15 and separation of the die-casting integrated body 10 for the overflow part 16, the overflow part 17, and the overflow part 18 The moving directions are parallel. The simplification of the structure of the jig 20 is promoted.

The separation of the overflow part and the die-cast product part synchronized with the die-casting will be described with reference to FIG. 13. In FIG. 13, M1 indicates a state of the mold 30. H (high) indicates the mold 30 in the closed state, and L (low) indicates the mold 30 in the open state. In M2, the H-level pulse (level pulse) indicates the falling timing of the overflow portion. In M3, the H-level pulse indicates the falling timing of the die-cast product portion 15. In M4, the H-level pulse indicates the timing at which the chuck 40 releases the runner 12. The horizontal axis of FIG. 13 is a time axis.

At time t1, the chuck 40 grasps the runner 12 of the die-casting integrated body 10 remaining in the lower mold 31 as a fixed mold. Between time t1 and time t2, the chuck 40 moves the grasped die-casting integrated body 10 away from the mold 30 in the horizontal direction. As a result, the die-cast integrated body 10 reaches the first position P1. Just before time t2, the chuck 40 starts to move the die-casting integrated body 10 from the first position P1 to the second position P2. Between time t2 and time t3, the intermediate overflow portion 16, the second end overflow portion 18, and the first end overflow portion 17 contact the first obstacle portion 26, the first obstacle portion 27, The first obstacle portion 28 falls down. At time t3, the die-cast integrated body 10 reaches the second position P2. Between time t3 and time t4, the die-cast integrated body 10 moves from the second position P2 to the third position P3. Just before time t4, the chuck 40 starts to move the die-casting integrated body 10 from the third position P3 to the fourth position P4. Between time t4 and time t5, the die-cast product part 15 comes into contact with the first obstacle part 26, the first obstacle part 27, and the first obstacle part 28 as the second obstacle part 25 having a different height and falls.

Between time t4 and time t5, after the die-cast product part 15 is dropped, the chuck 40 moves the die-cast integrated body 10 from the fourth position P4 to the fifth position P5 (refer to FIG. 1). It moves and releases the runner part 12 at the fifth position P5, so that the die-casting unit 10 drops. The released die-casting integrated body 10 is obtained by removing all of the die-casting product portion 15 and the overflow portion 16, the overflow portion 17, and the overflow portion 18. At time t6, the chuck 40 grasps the runner 12 of the die-casting integrated body 10 which is then die-casted by the mold 30. The description about time t6 to time t10 is the same as the description about time t1 to time t5, and is omitted.

As can be seen from the description, the overflow portion 16, the overflow portion 17, and the overflow portion 18 are separated from the die-casting body 10 in synchronization with the die-casting molding of the die-casting body 10 in the mold 30 and separated from the die-casting in the mold 30 The die-casting molding of the integrated body 10 separates the die-cast product part 15 from the die-cast integrated body 10 simultaneously. The chuck 40 taken out of the die-casting integrated product 10 from the mold 30 cooperates with the jig 20 to remove the overflow part and the die-casting product part from the die-casting integrated product 10. Even if the overflow part and the die-cast product part are removed from the die-cast integrated body 10 taken out from the mold 30, a delay in the die-casting molding cycle can be avoided or suppressed.

When the overflow part 16, the overflow part 17, the overflow part 18, and / or the die-cast product part 15 are separated from the die-casting integrated body 10, a die-casting forming step for another die-casting integrated body may be performed in the mold 30. FIG. 13 shows that when the mold 30 is closed in the cycle C2, the overflow portion falls from the die-casting integrated body 10 taken out from the die 30 in the cycle C1, and the die-casting product portion 15 falls from the die-casting integrated body 10. Even if the overflow part and the die-cast product part are removed from the die-cast integrated body 10 taken out from the mold 30, a delay in the die-casting molding cycle can be avoided or suppressed.

FIG. 14 illustrates a method for manufacturing a die-cast product part on one side of the present disclosure. A method for manufacturing a die-casting product part includes: integrally forming a die-casting product by die-casting with a mold 30; Step (S1) for removing the object 10 from the mold 30; contact the at least one first obstacle portion 26, the first obstacle portion 27, the first obstacle portion 28 with the overflow portion 16, the overflow portion 17, and the overflow portion 18 and Step (S2) of moving the die-casting integrated body 10 in a manner of separating the die-casting integrated body 10; and after the overflow portion 16, the overflow portion 17, and the overflowing portion 18 are separated from the die-casting integrated body 10, the die-casting product portion 15 contacts at least A step of moving the die-casting unit 10 such that the second obstacle 25 separates from the die-casting unit 10 (S3).

The removal of the overflow part 16, the overflow part 17, the overflow part 18, and the die-cast product part 15 from the die-casting integrated body 10 is facilitated and taken out continuously from the mold 30. The chuck 40 for allowing the die-casting integrated body 10 to be taken out of the mold 30 is allowed to be diverted. In some cases, the movement of the die-cast integrated body 10 occurs by the movement of the chuck 40 that clamps the flow path portion 11 of the die-cast integrated body 10. The chuck 40 can clamp the runner section 12 included in the flow path section 11, but it is not necessarily limited to this.

The manufacturing method of the die-casting part includes the step (S4) of releasing the die-casting integrated body 10 as an option. The chuck 40 releases the runner portion 12, so that the die-casting integrated body 10 can be released from the chuck 40. The die-cast integrated body 10 released from the chuck 40 includes the flow path portion 11 only, but is not necessarily limited thereto.

FIG. 15 shows a case where three pairs of die-cast product portions 15 are coupled to the common flow channel portion 13. Even in this case, in the same manner as described above, the overflow part 16, the overflow part 17, and the overflow part 18 are separated based on the movement of the die-casting integrated body 10, and then the die-cast product part 15 is separated. Thus, the same effects as described above are obtained. The number of the overflow part 16, the overflow part 17, and the overflow part 18 also increases in accordance with the increase in the number of die-cast product parts 15. The jig 20 includes a first obstacle portion and a second number which increase correspondingly. Obstacles 25, 26, 27, 28. The number of the die-cast product parts 15 included in one die-cast integrated body 10 is arbitrary. The same applies to the number of overflow parts corresponding to the increase of the die-cast product part 15.

As shown in FIGS. 16 and 17, in some cases, the first obstacle portion 26, the first obstacle portion 27, the first obstacle portion 28, and the second obstacle portion 25 are pillar portions protruding from the base portion 22, respectively. The first obstacle portion 26, the first obstacle portion 27, the pillar portion of the first obstacle portion 28, and the pillar portion of the second obstacle portion 25 are extension portions each extending so as to intersect or orthogonal to the moving direction of the die-cast integrated body 10. Or include extensions. The cross-sectional shape of the pillar portion may be circular, polygonal, or other shapes. Pillar portions are arranged two-dimensionally on the base portion 22, and a specific pillar portion is selectively used in order to drop the overflow portion 16 and the die-cast product portion 15 respectively. FIG. 17 shows the use of a column portion in which diagonal hatching is selectively used. The amount of protrusion of the selected column portion from the base portion 22 is set so that contact with the overflow portion 16 or the die-cast product portion 15 occurs. The amount of protrusion of the unselected column portion from the base portion 22 is set so that contact with the overflow portion 16 or the die-cast product portion 15 does not occur. It is not necessarily limited to this, and the two-dimensional arrangement of the pillar portions may be configured by arranging the rows of the pillar portions arranged in the vertical direction in a column direction (horizontal direction) orthogonal to the vertical direction. It is not necessarily limited to this, and the outline of the two-dimensional arrangement of the pillar portions is rectangular. The cross-sectional area or the arrangement density of the pillar portion can be appropriately set according to the application.

As shown in FIGS. 18 and 19, it is assumed that only the die-cast product portion 15 on the A side of the flow channel portion 13 and the overflow portion 16, the overflow portion 17, and the overflow portion 18 are formed, and only those corresponding to the A side are used. In the case of a part of the jig 20.
