Detailed Description

A non-limiting embodiment of the present invention will be described below with reference to fig. 1 to 19. Those skilled in the art may combine embodiments and/or features without undue experimentation. In addition, the synergistic effect resulting from the combination can also be understood by the person skilled in the art. Repetitive description between the embodiments is omitted in principle. The description of the invention is mainly for the purpose with reference to the drawings, and may be simplified for convenience of drawing.

In the following description, each feature described in relation to a method and/or jig for manufacturing a die-cast product section is understood not only as a combination with other features but also as an individual feature independent of other features. Individual features do not necessarily have to be combined with other features but are understood as separate individual features. All combinations of individual features are described which are redundant to a person skilled in the art and are therefore omitted. Individual features are indicated by the expression "a number of cases". The individual features are not, for example, effective only for the manufacturing method and/or jig of the die-cast product section illustrated in the drawings, but are rather general features that are also commonly used for manufacturing methods and/or jigs of other various die-cast product sections.

Fig. 1 is a diagrammatic view of a system 100 in accordance with an embodiment of the present disclosure. The system 100 includes: a die 30 for die-casting the die-cast integrated body 10; a chuck 40 for clamping the flow path portion 11 of the die-cast integrated object 10 and taking out the die-cast integrated object 10 from the die 30; and a jig 20 for separating the overflow 16, the overflow 17, the overflow 18, and the die cast product 15 from the die cast integral body 10. The movement path of the die cast integral unit 10 clamped by the clamping head 40 is indicated by a dashed arrow in fig. 1.

The die-cast integrated body 10 includes: the flow path portion 11, the one or more die-cast product portions 15 coupled to the flow path portion 11, and the one or

more relief portions

16, 17, and 18 (see fig. 2 and 3) coupled to at least the die-cast product portions 15. The flow path portion 11 of the die-cast integrated body 10 may include a runner portion 12 and a runner (runner) portion 13. The die-cast product portion 15 is a product or a product portion. Alternatively, the die-cast product section 15 is a semi-product or a semi-product portion.

In some cases, the die-cast product portion 15 is a metal part (metal parts) for a slide fastener (slide fastener). Specifically, the die-cast product portion 15 is a tab or a slider body. In some cases, the plurality of

overflow portions

16, 17, 18 are coupled to the respective die-cast product portions 15 at different positions. The

overflow portions

16, 17, and 18 shown in fig. 2 are named as a first end overflow portion 17, a second end overflow portion 18, and an intermediate overflow portion 16, respectively.

The die-cast product portion 15 is connected to the runner portion 13 via a gate (gate) portion 14. The intermediate overflow portion 16 is connected to the die cast product portion 15 via the gate portion 14. The first end relief portion 17 is connected to the die-cast product portion 15 and the runner portion 13 via the gate portion 14. The second terminal relief portion 18 is connected to the die-cast product portion 15 and the runner portion 13 via the gate portion 14. The gate portion 14 is a flow path portion connecting the flow path portion 13 and the die-cast product portion 15, a flow path portion connecting the overflow portion 16, the overflow portion 17, and the overflow portion 18 to the die-cast product portion 15, or a flow path portion connecting the overflow portion 16, the overflow portion 17, and the overflow portion 18 to the flow path portion 13. In other words, the gate portion 14 is not limited to the flow path portion connecting the runner portion 13 and the die-cast product portion 15.

The mold 30 includes a lower mold 31 and an upper mold 32. The lower mold 31 and the upper mold 32 may be a fixed mold or a movable mold. The mold 30 is opened by separating the upper mold 32 from the lower mold 31, separating the lower mold 31 from the upper mold 32, or a combination thereof. The mold 30 is closed by bringing the upper mold 32 close to the lower mold 31, or by bringing the lower mold 31 close to the upper mold 32, or by a combination of these. The lower die 31 and the upper die 32 are mounted on die mounting surfaces of a die-casting machine, not shown. The shorter cycle time of the die-casting (for example, the time required for the cycle C1, the cycle C2, and the cycle C3 of fig. 13) contributes to a reduction in the manufacturing cost of the die-cast product portion 15.

One cycle of die-casting includes: the mold 30 is closed, and the melt (molten metal) is supplied into the mold 30, the mold 30 is cooled, and the mold 30 is opened. The mold 30 may include: a flow path for the melt, a cavity (cavity) with a space communicating with the flow path, and an overflow with a space communicating with the cavity and/or the flow path. The flow path of the melt may include runners and channels. Melt flowing into the runner flows into the runner, and then into the mold cavity and/or the overflow. The melt inflow space flowing into each mold cavity is communicated to the overflow of each mold cavity. The runner and the cavity are in spatial communication via a gate. The runner and the overflow are spatially communicated through the gate.

The molten metal supplied to the mold 30 becomes solid by cooling of the mold 30. The die-cast product portion 15 of the die-cast integrated product 10 is a metal portion which flows into the cavity of the die 30 and is solidified. The

overflow portions

16, 17, and 18 of the die-cast integrated product 10 are metal portions that flow into the overflow of the mold 30 and are solidified. The flow path portion 11 of the die-cast integrated product 10 is a metal portion which flows into the flow path of the die 30 and is solidified. When the flow path of the die 30 includes a runner and a flow path, the flow path portion 11 of the die-cast integrated product 10 includes a runner portion 12 and a flow path portion 13. The gate portion 14 of the die-cast integrated product 10 is a metal portion which flows into the gate of the mold 30 and is solidified.

The gate has a small volume compared to the runner, cavity, overflow. The die cast product portion 15 can be easily separated from the die cast integral product 10 by breaking the gate portion 14. The same applies to the separation of the relief portion 16, the relief portion 17, and the relief portion 18 from the press-cast integrated product 10. In some cases, the mold 30 includes a gate for connecting the runner to the overflow, and the die-cast integrated product 10 includes a gate portion 14 for connecting the runner portion 13 to the overflow 17 and the overflow 18.

In some cases, the die cast product portions 15 are provided symmetrically with respect to the flow path portion 13 of the die cast integrated product 10. A plurality of

overflow portions

16, 17, and 18 are additionally provided symmetrically with respect to the flow path portion 13. In fig. 2, "a" is given to one side (upper side of the sheet of fig. 2) of the flow path portion 13, and "B" is given to the other side (lower side of the sheet of fig. 2) of the flow path portion 13. The die-cast product portion 15 on the a side and the die-cast product portion 15 on the B side are symmetrical with respect to the runner portion 13. The

overflow

16, 17, and 18 on the a side and the

overflow

16, 17, and 18 on the B side are symmetrical with respect to the flow path portion 13.

As described above, the collet 40 clamps the flow path portion 11 of the die cast integral product 10 and takes out the die cast integral product 10 from the die 30. The clip 40 clamps the flow path portion 11 of the die-cast integrated product 10 by any method such as grasping, suction, or adsorption. The system 100 includes a mechanism to move the chuck 40. The mechanism for moving the chuck 40 may include a first linear actuator and a second linear actuator. The first linear actuator moves the collet 40 in the direction of removal of the die cast integral unit 10 from the die 30. The second linear actuator moves the collet 40 in a direction intersecting with or orthogonal to the direction of taking out the die-cast integrated article 10 from the die 30. When the first linear actuator and the second linear actuator are ball screws, the screw shaft of one of the ball screws may be fixed to the nut of the other ball screw. In another case, the collet 40 is attached to the tip of a robot arm (robot arm) having links connected by joints. The pivoting or rotation of a certain link relative to the base or other links is performed based on instructions from the control section, and finally the change in the posture of the robot arm and the displacement of the chuck 40 are achieved.

The jig 20 for separating the overflow 16, the overflow 17, the overflow 18, and the die-cast product 15 from the die-cast integrated product 10 includes: at least one first barrier 26, one first barrier 27, and one first barrier 28 provided so as to contact the

overflow

16, 17, and 18 of the die-cast integrated product 10 while the die-cast integrated product 10 is moving; and at least one second barrier portion 25 provided so as to contact the die-cast product portion 15 of the die-cast integral body 10 while the die-cast integral body 10 is moving. The terms first and second are used to distinguish between the obstacle for separating the relief portion 16, the relief portion 17, and the relief portion 18 from the die-cast integral product 10 and the obstacle for separating the die-cast product portion 15 from the die-cast integral product 10. The first and second do not mean the order of the first or second.

The jig 20 may include: the option is a base portion 22 to which the first and

second barrier portions

25, 26, 27, and 28 are fixed, and a plate (plate)21 on which the base portion 22 is disposed. The plate 21 includes an opening 21a for avoiding interference with the die-cast integrated body 10 which is clamped and moved by the clamp 40. In some cases, the pair of base portions 22 are disposed so as to sandwich the opening 21a of the plate 21. One base portion 22 included in the pair of base portions 22 is provided with first and

second barrier portions

25, 26, 27, and 28 that the die-cast product portion 15 on one side of the runner portion 13 should contact the

overflow portions

16, 17, and 18. The other base portion 22 included in the pair of base portions 22 is provided with first and

second barrier portions

25, 26, 27, and 28 that the die-cast product portion 15 on the other side should contact the overflow portion 16, the overflow portion 17, and the overflow portion 18 with respect to the runner portion 13.

The first barrier portion 26, the first barrier portion 27, the first barrier portion 28, and the second barrier portion 25 each include an extension portion extending so as to intersect or be orthogonal to the moving direction of the die-cast integrated object 10. Specifically, the first barrier 26, the first barrier 27, and the first barrier 28 include extensions extending so as to intersect or be orthogonal to the moving direction of the die-cast integrated object 10 for separating the overflow 16, the overflow 17, and the overflow 18. The second barrier portion 25 includes an extension portion extending so as to intersect or be orthogonal to the moving direction of the die-cast integral body 10 for separating the die-cast product portion 15.

The extensions of the first obstacle 26, the first obstacle 27, the first obstacle 28, and the second obstacle 25 may be positioned at different positions or heights in a certain direction. For example, when a certain direction is the vertical direction, the extension portion of the second barrier portion 25 is positioned higher or lower than the extension portions of the first barrier portion 26, the first barrier portion 27, and the first barrier portion 28. When the die-cast integral body 10 is supposed to move upward in the vertical direction, the extending portions of the second barrier portions 25 are positioned higher than the extending portions of the first barrier portions 26, the first barrier portions 27, and the first barrier portions 28. When the die-cast integrated product 10 is supposed to move downward in the vertical direction, the extending portions of the second barrier portions 25 are positioned lower than the extending portions of the first barrier portions 26, the first barrier portions 27, and the first barrier portions 28. In any case, the

first barrier portions

26, 27, 28 contact the

overflow portions

16, 17, 18 earlier than the second barrier portions 25 contact the die cast product portion 15.

It is assumed that the die-cast integral body 10 taken out of the die 30 takes various movement trajectories. The first and second blocking portions are disposed at appropriate positions corresponding to the movement locus of the die-cast integrated body 10. The relative positions of the die cast product portion 15, the relief portion 16, the relief portion 17, and the relief portion 18 in the die cast integrated product 10 are also considered. When the relative positions of the die-cast product portion 15 and the

relief portions

16, 17, 18 change in the die-cast integrated body 10, the relative positions of the first barrier portion 26, the first barrier portion 27, the first barrier portion 28, and the second barrier portion 25 can be changed.

When the first and second barriers 25 to 28 are arranged in this order in the direction of taking out the die cast integral unit 10 from the die 30, the

overflow

16, 17, and 18 can be easily separated from the die cast integral unit 10, and the die cast product 15 can be easily separated from the die cast integral unit 10. When the first and second blocking portions 25 to 28 are arranged in this order in the direction of taking out the die cast integral unit 10 from the die 30, the first and second blocking portions 25 to 28 are arranged at different positions or heights in a direction (for example, a vertical direction) orthogonal to the direction of taking out the die cast integral unit 10 from the die 30.

In some cases, the direction of taking out the die-cast integrated product 10 from the die 30 is a direction that coincides with or extends along a horizontal direction orthogonal to the vertical direction. The first and second obstacles 25 to 28 are disposed at different positions or heights in the vertical direction.

In some cases, the plurality of

first barriers

26, 27, and 28 include at least a pair of

first barriers

26, 27, and 28 provided with a space therebetween through which the flow path portion 13 included in the flow path portion 11 for press-casting the integrated object 10 passes. The plurality of second barriers 25 include at least one pair of second barriers 25 provided with a space therebetween through which the runner 13 of the integrated product 10 is to be press-cast. The plurality of

first barriers

26, 27, and 28 may be arranged symmetrically with respect to a space through which the runner 13 included in the flow path 11 for the press-casting of the integrated object 10 passes. The plurality of second barriers 25 may be symmetrically arranged with respect to a space through which the runner 13 for press-casting the integrated object 10 passes.

When the runner 13 moves, the

overflow portions

16, 17, and 18 symmetrically provided with respect to the runner 13 contact the

first barrier

26, 27, and 28 provided so as to partition the movement space of the runner 13, and are separated from the die-cast integrated body 10. The relief portion 16, the relief portion 17, and the relief portion 18 separated from the press-cast integral product 10 can fall downward in the vertical direction following the gravity. When the runner section 13 moves, the die-cast product sections 15 symmetrically provided with respect to the runner section 13 contact the second barrier section 25 provided so as to partition the movement space of the runner section 13, and are separated from the die-cast integrated body 10. The die cast product portion 15 separated from the die cast integral body 10 can be dropped in the vertical direction downward following the gravity. The

overflow

16, 17, 18 and the die cast product portion 15 are separated at different timings. Therefore, the overflow portion 16, the overflow portion 17, the overflow portion 18, and the die-cast product portion 15 are not necessarily limited to this, and they can be separately managed by dropping them into different cases. The die cast product portion 15 separated from the die cast integral body 10 is optionally ground and burrs caused by parting lines of the die are removed.

When the

overflow portions

16, 17, and 18 are asymmetrically provided with respect to the flow path portion 13, the

first barrier portions

26, 27, and 28 are asymmetrically provided with respect to the movement space of the flow path portion 13. In the case where the die-cast product portion 15 is disposed asymmetrically with respect to the flow path portion 13, the second barrier portion 25 is disposed asymmetrically with respect to the movement space of the flow path portion 13.

Each of the first barrier portion 26, the first barrier portion 27, the first barrier portion 28, and/or the second barrier portion 25 may be a flat plate member bent at least one portion. The contact timing and the contact position of the first barrier 26, the first barrier 27, the first barrier 28 with the relief portion 16, the relief portion 17, and the relief portion 18, and the contact timing and the contact position of the second barrier 25 with the die-cast product portion 15 can be easily set.

The first barrier portion 26, the first barrier portion 27, the first barrier portion 28, and/or the second barrier portion 25 may be L-shaped members 23 fixed to the base portion 22, respectively. The L-shaped member 23 includes a first flat plate 23d and a second flat plate 23e, and is bent between the first flat plate 23d and the second flat plate 23 e. The wide side surface of the first plate 23d is placed and fixed on the side surface of the base portion 22. The end of the first flat plate 23d abuts on the main surface of the plate 21. The main surface of the plate 21 is one of a pair of surfaces that define the thickness of the plate 21. The second plate 23e extends in a direction perpendicular to the vertical direction and away from the base portion 22. The die-cast product portion 15, the overflow portion 16, the overflow portion 17, and the overflow portion 18 contact the second flat plate 23e of the L-shaped member 23. The length of the second plate 23e is set so that the die-cast product portion 15, the relief portion 16, the relief portion 17, and the relief portion 18 contact and fall more reliably. By appropriately setting the length of the first flat plate 23d, the height of the second flat plate 23e in the vertical direction can be appropriately set.

It is assumed that the height of the second barrier portion 25 in the vertical direction is higher than the height of the first barrier portion 26, the first barrier portion 27, and the first barrier portion 28 in the vertical direction (see fig. 6). The overflow 16, the overflow 17, and the overflow 18 are easily separated from the die-cast integral product 10, and the die-cast product 15 is easily separated from the die-cast integral product 10. It is assumed that the spacing W26, the spacing W27, and the spacing W28 of the space between the pair of first obstacles 26, the first obstacles 27, and the first obstacles 28 are different from the spacing W25 of the space between the pair of second obstacles 25.

The number of first obstacles may depend on the number of overflows. The number of the second barrier portions may depend on the number of the die-cast product portions. One first barrier portion or a plurality of first barrier portions is provided corresponding to one overflow portion. One second barrier portion or a plurality of second barrier portions is provided corresponding to one die-cast product portion. In the case of fig. 4, six first barriers are provided corresponding to the total of six relief portions. Two second barrier portions are provided corresponding to the total of two die-cast product portions.

Hereinafter, based on the above description, the relief portion 16, the relief portion 17, the relief portion 18, and the die cast product portion 15 are more specifically described with respect to being separated from the die cast integral body 10. The runner portion 12 of the die-cast integral body 10 is gripped by the collet 40 and taken out of the die 30, and sequentially displaced to a first position P1 to a fourth position P4. The direction from the mold 30 to the first position P1 is the horizontal direction, the direction from the first position P1 to the second position P2 is the vertical direction, the direction from the second position P2 to the third position P3 is the horizontal direction, and the direction from the third position P3 to the fourth position P4 is the vertical direction.

As can be seen from fig. 7 to 10, all of the

overflow portions

16, 17, and 18 are removed from the die cast unitary body 10 in the process of the die cast unitary body 10 reaching the second position P2 from the first position P1. When the die-cast integral product 10 is at the first position P1, the overflow portion 16, the overflow portion 17, and the overflow portion 18 do not fall (see fig. 7). When the die cast integral product 10 is moved upward in the vertical direction toward the second position P2, the intermediate relief portion 16 first comes into contact with the first barrier portion 26, and the gate portion 14 is bent and dropped (see fig. 8). When the die-cast integral object 10 is further moved upward in the vertical direction toward the second position P2, the second terminal relief portion 18 comes into contact with the first barrier portion 28, and the gate portion 14 is bent and falls (see fig. 9). When the die-cast integral product 10 is further moved upward in the vertical direction toward the second position P2, the first terminal relief portion 17 comes into contact with the first barrier portion 27, and the gate portion 14 is bent and falls (see fig. 10).

After all the

overflow portions

16, 17, and 18 are removed from the die-cast unitary body 10, the die-cast unitary body 10 is moved from the second position P2 to the third position P3 in the horizontal direction, and then the die-cast unitary body 10 is moved from the third position P3 to the fourth position P4 in the vertical direction upward. The die-cast integral object 10 is moved from the second position P2 to the third position P3 in order to dispose the die-cast product section 15 directly below the second barrier section 25. The movement of the die cast integral unit 10 from the third position P3 to the fourth position P4 is performed to remove the die cast product portion 15 from the die cast integral unit 10.

In some cases, the movement of the die-cast integral unit 10 from the second position P2 to the third position P3 is performed after the movement of the die-cast integral unit 10 for separating the

overflow portion

16, 17, and 18 and before the movement of the die-cast integral unit 10 for separating the die-cast product portion 15, by moving the die-cast integral unit 10 in the direction of taking out the die-cast integral unit 10 from the mold 30. Assume a case where the second obstacle portion 25 is positioned vertically above the first obstacle portion 26, the first obstacle portion 27, and the first obstacle portion 28.

When the die-cast integral unit 10 is at the third position P3 (see fig. 11), the die-cast product portion 15 remains coupled to the flow path portion 13. When the die cast integral body 10 moves upward in the vertical direction from the third position P3 toward the fourth position P4, the die cast product portion 15 contacts the second barrier portion 25 and falls (see fig. 12).

The direction of movement of the die-cast integral object 10 for separating the

overflow

16, 17, 18 and/or the direction of movement of the die-cast integral object 10 for separating the die-cast product 15 is different from the direction of removal of the die-cast integral object 10 from the mold 30. The jig 20 is facilitated to be a stationary member or a fixed member.

The moving direction of the die-cast integral object 10 for separating the die-cast product portion 15 is parallel to the moving direction of the die-cast integral object 10 for separating the

overflow portions

16, 17, 18. The simplification of the structure of the jig 20 is promoted.

Referring to fig. 13, the separation of the relief portion and the die-cast product portion in synchronization with the die-cast molding is described. In fig. 13, M1 represents the 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, an H level pulse (level pulse) indicates the fall timing of the overflow portion. In M3, the H-level pulse indicates the falling timing of the die-cast product part 15. In M4, an H-level pulse indicates the timing at which the collet 40 releases the runner portion 12. The horizontal axis of fig. 13 is a time axis.

At time t1, the collet 40 grips the runner portion 12 of the die-cast integral product 10 remaining in the lower die 31 as the fixed die. Between time t1 and time t2, the collet 40 moves the gripped die cast integral piece 10 in the horizontal direction away from the die 30. As a result, the die-cast one-piece object 10 reaches the first position P1. Just prior to time t2, the collet 40 begins to move the die cast unitary body 10 from the first position P1 toward the second position P2. Between time t2 and time t3, intermediate overflow portion 16, second tip overflow portion 18, and first tip overflow portion 17 contact first obstacle portion 26, first obstacle portion 27, and first obstacle portion 28 of different heights in this order and fall. At time t3, the die-cast integral body 10 reaches the second position. Between time t3 and time t4, die-cast integral object 10 moves from the second position to third position P3. Just before time t4, the clamping head 40 begins to move the die cast integral unit 10 from the third position P3 to the fourth position P4. Between time t4 and time t5, die-cast product portion 15 falls while contacting first barrier portion 26, first barrier portion 27, and first barrier portion 28 as second barrier portion 25 having different heights.

After the die cast product portion 15 falls between time t4 and time t5, the collet 40 moves the die cast integral unit 10 from the fourth position P4 to the fifth position P5 (see fig. 1), and releases the runner portion 12 at the fifth position P5, whereby the die cast integral unit 10 falls. The released die cast integral product 10 is obtained by removing all of the die cast product portion 15, the overflow portion 16, the overflow portion 17, and the overflow portion 18. At time t6, the clip 40 grips the runner portion 12 of the die-cast integral product 10 which is then die-cast by the die 30. The description of the time t6 to the time t10 is the same as that of the time t1 to the time t5, and is omitted.

As is apparent from the above description, the overflow portion 16, the overflow portion 17, and the overflow portion 18 are separated from the die-cast integral body 10 in synchronization with the die-cast integral body 10 in the die 30, and the die-cast product portion 15 is separated from the die-cast integral body 10 in synchronization with the die-cast integral body 10 in the die 30. The clip 40 for taking out the die-cast integrated body 10 from the die 30 cooperates with the jig 20 to remove the overflow portion and the die-cast product portion from the die-cast integrated body 10. Even if the overflow portion and the die-cast product portion are removed from the die-cast integrated product 10 taken out from the die 30, delay in the die-casting molding cycle can be avoided or suppressed.

When the

overflow

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

Fig. 14 describes a method for manufacturing a die-cast product section on one side of the present disclosure. The method for manufacturing the die-cast product portion includes: a step (S1) of taking out the die-casting integrated object (10) die-cast by the die (30) from the die (30); a step (S2) of moving the die cast integral product 10 so that the overflow part 16, the overflow part 17, and the overflow part 18 contact at least one of the first obstacle 26, the first obstacle 27, and the first obstacle 28 and are separated from the die cast integral product 10; and a step (S3) of moving the die cast integral body 10 so that the die cast product portion 15 contacts the at least one second obstacle portion 25 and separates from the die cast integral body 10 after the overflow portion 16, the overflow portion 17, and the overflow portion 18 separate from the die cast integral body 10.

The removal of the

overflow

16, 17, 18 and the die cast product portion 15 from the die cast integral product 10 is promoted continuously with the removal of the die cast integral product 10 from the mold 30. The clip 40 is allowed to be transferred to the die casting integrated object 10 taken out from the die 30. In some cases, the movement of the die cast integrated product 10 is caused by the movement of the collet 40 that clamps the flow path portion 11 of the die cast integrated product 10. The collet 40 can clamp the runner portion 12 included in the flow path portion 11, but is not necessarily limited thereto.

The method of manufacturing the die-cast product portion includes a step (S4) of releasing the die-cast integrated product 10 as an option. The clip 40 releases the runner portion 12, thereby allowing the die cast integral body 10 to be released from the clip 40. The die-cast integrated product 10 released from the collet 40 includes only the flow path portion 11, but is not necessarily limited thereto.

Fig. 15 shows a case where three pairs (pairs) of die-cast product portions 15 are coupled to the common runner portion 13. In this case as well, the die cast product portion 15 is separated after the

overflow portions

16, 17, and 18 are separated based on the movement of the die cast integrated product 10, as described above. Thus obtaining the same effect as described. The number of the

overflow portions

16, 17, 18 increases in accordance with the increase in the number of the die-cast product portions 15. The jig 20 includes a correspondingly increased number of first and

second barrier portions

25, 26, 27, 28. The number of die-cast product portions 15 included in one die-cast integrated body 10 is arbitrary. The same applies to the number of overflow portions that increase in response to an increase in the die cast product portion 15.

As shown in fig. 16 and 17, in some cases, each of the first barrier portion 26, the first barrier portion 27, the first barrier portion 28, and the second barrier portion 25 is a pillar portion protruding from the base portion 22. The pillar portions of the first barrier portion 26, the first barrier portion 27, and the first barrier portion 28, and the pillar portion of the second barrier portion 25 are respectively extended portions extending so as to intersect or be orthogonal to the moving direction of the die-cast integral body 10, or include extended portions. The cross-sectional shape of the pillar portion may be circular, polygonal, or other shapes. A column portion is two-dimensionally arranged in the base portion 22, and a specific column portion is selectively used for dropping of each of the overflow portion 16 and the die-cast product portion 15. Fig. 17 shows that the pillar portions hatched with diagonal lines are selectively used. The amount of protrusion of the selected pillar portion from the base portion 22 is set so as to contact the relief portion 16 or the die-cast product portion 15. The amount of protrusion of the unselected pillar portion from the base portion 22 is set so as not to contact the relief portion 16 or the die cast product portion 15. The two-dimensional arrangement of the pillar portions is not necessarily limited to this, and may be configured such that the columns of pillar portions arranged in the vertical direction are arranged in a column direction (horizontal direction) orthogonal to the vertical direction. The outline of the two-dimensional arrangement of the pillar portions is not necessarily limited to this. The cross-sectional area or arrangement density of the pillar portions can be appropriately set according to the application.

As shown in fig. 18 and 19, it is assumed that only the die-cast product portion 15 on the a side of the flow path portion 13 is molded with the relief portion 16, the relief portion 17, and the relief portion 18, and only the portion of the jig 20 corresponding to the a side is used.

Based on the teachings, one of ordinary skill in the art may apply various modifications to the embodiments. The reference signs in the claims are for reference and shall not be construed as limiting the scope of the claims.
