Modes for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted. The dimensional ratios in the drawings do not necessarily match those in the description. The terms “upper”, “lower”, “front”, and “rear” are based on the illustrated state and are for convenience.

[0009] [Modeling System] FIG. 1 is a perspective view showing an initial state of a molding system including a core subset device according to an embodiment. The X direction (second direction) and Y direction (first direction) in the figure are horizontal directions, and the Z direction is a vertical direction. The X direction, Y direction, and Z direction are axial directions orthogonal to each other in a rectangular coordinate system of a three-dimensional space. Hereinafter, the X direction is also referred to as the front-rear direction, the Y direction as the lateral direction, and the Z direction as the up-down direction. The molding system 100 shown in FIG. 1 includes an upper mold (not shown) and a lower mold M, and molds a mold in which cores are arranged inside. The molding system 100 includes a molding machine 1 and a core subset device 10.

[0010] The molding machine 1 includes an upper frame 2, a lower frame 3, and a pair of frame guide members 4. In the initial state of the molding system 100 shown in FIG. 1, an upper mold and a lower mold M molded in the upper frame 2 and the lower frame 3 are arranged. The upper frame 2 and the lower frame 3 are arranged to face each other in the up-down direction. The upper mold and the lower mold M face each other in the Z direction in a state of being arranged in the upper frame 2 and the lower frame 3.

[0011] The upper frame 2 is a box-shaped frame body with openings at the upper end and the lower end, and has a space inside that can accommodate a model arranged on the upper surface of a pattern member (not shown). The pattern member is a plate member on which a model can be arranged. The model is arranged on at least one of the upper surface and the lower surface of the pattern member. The lower end of the upper frame 2 can abut, for example, on the upper surface of the pattern member. A sand inlet penetrating from the outside to the internal space is provided on the side wall of the upper frame 2. The lower frame 3 is a box-shaped frame body with openings at the upper end and the lower end, and has a space inside that can accommodate a model arranged on the lower surface of a pattern member. The upper end of the lower frame 3 can abut, for example, on the lower surface of the pattern member. A sand inlet penetrating from the outside to the internal space is provided on the side wall of the lower frame 3.

[0012] The frame guide member 4 is a rod member that guides the upper frame 2 and the lower frame 3, and extends in the vertical direction. The frame guide member 4 has, for example, a cylindrical shape. The upper frame 2 and the lower frame 3 are movably connected to the frame guide member 4. A cylinder 6 for driving the upper frame 2 in the vertical direction is connected to the upper frame 2. A cylinder 7 for driving the lower frame 3 in the vertical direction is connected to the lower frame 3. The cylinders 6 and 7 are, for example, hydraulic cylinders, air cylinders, or electric cylinders. The upper frame 2 and the lower frame 3 approach or separate from each other when at least one of the upper frame 2 and the lower frame 3 moves.

[0013] The upper frame 2 and the lower frame 3 approach each other when one or both of them move, and sandwich and connect the pattern member. The molding space of the aligned upper frame 2 and lower frame 3 is filled with sand from the sand inlet. The sand filled inside the upper frame 2 and the lower frame 3 is pressed toward the pattern member by an upper squeeze plate (not shown) and a lower squeeze plate (not shown). Thereby, the upper mold and the lower mold M are molded. After the upper mold and the lower mold M are molded, the upper frame 2 and the lower frame 3 are separated in the vertical direction, and the pattern member is carried out, whereby the molding system 100 returns to the initial state.

[0014] [Core setting device] The core setting device 10 is a device for setting cores (not shown) in the lower mold M disposed opposite to the upper mold. The core setting device 10 includes a holding jig 11, a support arm 12, a rotation mechanism 13, a forward and backward movement mechanism (second movement mechanism) 14, and a lateral movement mechanism (first movement mechanism) 15. The holding jig 11 has a holding surface 11a for holding the core. The holding jig 11 has a substantially rectangular parallelepiped shape with the holding surface 11a as one surface. The holding surface 11a has a rectangular shape. The thickness of the holding jig 11 (the length of the holding jig 11 in the direction perpendicular to the holding surface 11a) is shorter than the long side and the short side of the holding surface 11a. The holding jig 11 has, for example, suction means, and sucks and holds the core by the suction means. The holding jig 11 may have claw portions and hold the core by the claw portions.

[0015] The support arm 12 is a member that supports the holding jig 11. The support arm 12 supports the holding jig 11 in a cantilever manner. The support arm 12 includes a first portion 12a connected to the holding jig 11 and a second portion 12b connected to the rotation shaft 13a of the rotation mechanism 13. The first portion 12a is provided so as to protrude from the side surface 11b of the holding jig 11. The side surface 11b is a surface adjacent to one short side of the holding surface 11a. The first portion 12a is connected to one end portion of the holding surface 11a in the short side direction on the side surface 11b and extends in a direction (Y direction) parallel to the rotation shaft 13a. The second portion 12b extends in a direction orthogonal to the rotation shaft 13a and connects the first portion 12a and the rotation shaft 13a.

[0016] The rotation mechanism 13 has a rotation shaft 13a parallel to the Y direction and a drive unit 13b. The drive unit 13b is a motor and rotationally drives the holding jig 11 about the rotation shaft 13a.

[0017] The forward and backward movement mechanism 14 moves the rotation mechanism 13 together with the holding jig 11 and the support arm 12 along the X direction. The forward and backward movement mechanism 14 has a rail member 14a and a cylinder 14b. The rail member 14a extends in the X direction. The rotation mechanism 13 is movably attached to the rail member 14a. The cylinder 14b moves the rotation mechanism 13 in the X direction along the rail member 14a. The cylinder 14b is, for example, an electric cylinder.

[0018] The lateral movement mechanism 15 moves the forward and backward movement mechanism 14, the holding jig 11, the support arm 12, and the rotation mechanism 13 along the Y direction. The lateral movement mechanism 15 includes a rail member 15a, a drive unit 15b, and a link mechanism 15c. The rail member 15a extends in the Y direction. The rotation mechanism 13 is movably attached to the rail member 15a. The drive unit 15b is a motor and moves the forward and backward movement mechanism 14 in the Y direction. Accordingly, the holding jig 11 moves between a position P2 (see FIGS. 2 and 3) and a position P3 (see FIGS. 4 and 5). The link mechanism 15c is connected to the drive unit 15b and the forward and backward movement mechanism 14. The drive unit 15b moves the forward and backward movement mechanism 14 in the Y direction along the rail member 15a by the link mechanism 15c.

[0019] [Operation of the Molding System] With reference to FIGS. 1 to 12, the operation of the molding system 100 will be described. In the initial state of the molding system 100 shown in FIG. 1, the holding jig 11 is disposed at a position P1 adjacent to the molding machine 1 in the X direction. At the position P1, the holding surface 11a faces upward and is kept parallel to the horizontal directions (the X direction and the Y direction). In the molding system 100, first, in the initial state, the step of placing the core on the holding surface 11a is performed by the operator. The working position of the operator is a position that sandwiches the holding jig 11 at the position P1 between the operator and the molding machine 1 in the X direction. The operator places the core on the holding surface 11a and operates the suction means to hold the core by the holding jig 11. The position P1 is provided in the front space (hereinafter, referred to as the "front space") in front of the molding machine 1 (the upper mold and the lower mold M). Here, the front of the molding machine 1 is the front of the molding machine 1 as viewed from the operator, and is the surface of the molding machine 1 facing the operator in the X direction. The front space is a space adjacent to the front of the molding machine 1 in the X direction. The working position of the operator is also provided in the front space.

[0020] Next, a process of retracting the holding jig 11 from between the molding machine 1 and the operator is performed. The process of retracting the holding jig 11 includes a process of rotating the holding jig 11 90° clockwise (hereinafter, "positive direction") when viewed from the negative side to the positive side in the Y direction, and a process of moving the holding jig 11 in the -Y direction. In the process of rotating the holding jig 11 90° in the positive direction, the holding jig 11 rotates about the rotation axis 13a of the rotation mechanism 13 while holding the core, and is moved from the position P1 to the position P2 shown in FIGS. 2 and 3. At the position P2, the holding surface 11a is arranged parallel to the Z direction and faces the space S between the upper frame 2 and the lower frame 3 in the X direction. The position P2 is also provided in the front space. Therefore, the process of rotating the holding jig 11 90° in the positive direction is performed in the front space.

[0021] In the process of moving the holding jig 11 in the -Y direction, the holding jig 11 is moved from the position P2 to the position P3 shown in FIGS. 4 and 5 by the lateral movement mechanism 15. Thereby, the holding jig 11 retracts from between the molding machine 1 and the operator. The position P3 is provided in a space adjacent in the Y direction to the front space (hereinafter, "adjacent space"). That is, by the process of moving the holding jig 11 in the -Y direction, the holding jig 11 moves from the front space to the adjacent space. Subsequently, a process of moving the holding jig 11 in the X direction by the back-and-forth movement mechanism 14 is performed, and the holding jig 11 moves from the position P3 to the position P4 shown in FIG. 6. The position P4 is also provided in the adjacent space. While the holding jig 11 has retracted from between the operator and the molding machine 1 to the adjacent space, the operator visually inspects the upper mold and the lower mold M before setting the core. In the visual inspection, the presence or absence of foreign matter, chipping, etc. in the upper mold and the lower mold M is inspected.

[0022] Subsequently, a step of moving the holding jig 11 in the Y direction is performed. In the step of moving the holding jig 11 in the Y direction, the holding jig 11 is moved from the position P4 to the position P5 shown in FIGS. 7 and 8 by the lateral movement mechanism 15. At the position P5, the holding surface 11a faces the space S in the X direction. By moving the holding jig 11 from the position P3 to the position P4 in the previous step, the distance between the holding surface 11a and the space S is shorter at the position P5 than when it is not moved. The position P5 is also provided in the front space. That is, by the step of moving the holding jig 11 in the Y direction, the holding jig 11 moves from the adjacent space to the front space.

[0023] Subsequently, a step of rotating the holding jig 11 by 90° in the positive direction is performed. In the step of rotating the holding jig 11 by 90° in the positive direction, the holding jig 11 rotates about the rotation axis 13a of the rotation mechanism 13 while holding the core, and thus moves from the position P5 to the position P6 (core setting position) shown in FIG. 9. At the position P6, the holding jig 11 is disposed within the space S, and the holding surface 11a faces the upper surface Ma (product surface) of the lower mold M in the Z direction.

[0024] Subsequently, a step of raising the lower frame 3 together with the lower mold M toward the holding jig 11 by the cylinder 7 is performed. As a result, as shown in FIG. 10, the upper surface Ma of the lower mold M and the holding surface 11a of the holding jig 11 are in a proximate state. In this state, the holding jig 11 releases the holding of the core by stopping the operation of the suction means and sets the core on the lower mold M.

[0025] Subsequently, a step of lowering the lower frame 3 together with the lower mold M by the cylinder 7 is performed. As a result, as shown in FIG. 11, the lower mold M and the holding jig 11 are in a separated state in the Z direction.

[0026] Subsequently, a step of rotating the holding jig 11 in the direction opposite to the positive direction, that is, counterclockwise (hereinafter referred to as the "negative direction") by 180° when viewed from the negative side to the positive side in the Y direction, and a step of moving the holding jig 11 in the -X direction are performed in parallel. In the step of rotating the holding jig 11 by 180° in the negative direction, the holding jig 11 rotates about the rotation axis 13a of the rotation mechanism 13. The step of moving the holding jig 11 in the -X direction is performed by the forward and backward movement mechanism 14, and the holding jig 11 moves toward the operator. As a result, the holding jig 11 moves from the position P6 to the position P1 as shown in FIG. 12.

[0027] After the holding jig 11 moves outside the space S, the frame alignment step is started. Here, the lower frame 3 is lifted toward the upper frame 2 by the cylinder 7 to perform frame alignment. Subsequently, the mold is manufactured by removing the frame and performing mold extrusion.

[0028] [Summary of the Embodiment] According to the core subset device 10, the holding jig 11 rotates 90° about the rotation axis 13a of the rotation mechanism 13, thereby moving between the position P5 outside the space S and the position P6 where the holding surface 11a faces the upper surface Ma of the lower mold M in the Z direction. That is, the holding jig 11 moves between the front space and the space S only by rotational movement. Therefore, compared with the case where the core holding means is retracted from between the lower mold and the upper mold, and after rotating the direction in which the core holding means faces by 180° at the retracted position, the core holding means is advanced to the position between the lower mold and the upper mold as in the core subset device described in Patent Document 1, the holding jig 11 can be moved more efficiently and the core can be set. For this reason, it is possible to contribute to shortening the cycle time.

[0029] Since the core subset device 10 includes the lateral movement mechanism 15 that moves the holding jig 11 along the Y direction outside the space S, the holding jig 11 can be moved to a position separated from the molding machine 1. Therefore, the operator can easily visually inspect the upper mold and the lower mold M. Therefore, the workability of the operator can be improved.

[0030] When the holding jig 11 is retracted from between the molding machine 1 and the operator, it rotates 90° in the positive direction in the front space (moves from position P1 to position P2). Also, when the holding jig 11 is moved from the space S to outside the space S, it rotates 180° in the negative direction using the space from the space S to the front space (moves from position P6 to position P1). In this way, the holding jig 11 does not need to rotate 180° only in the front space. Therefore, in the present embodiment, the operating range of the holding jig 11 in the front space can be made as narrow as possible. As a result, the workability of the operator can be further improved, contributing to shortening the cycle time.

[0031] The holding jig 11 moves along the Y direction by the lateral movement mechanism 15 in a state where the holding surface 11a is arranged parallel to the Z direction. The thickness of the holding jig 11 is smaller than the long side and the short side of the holding surface 11a. Therefore, compared with the case of moving the holding jig 11 with the holding surface 11a facing the Z direction, the space in the X direction required for the movement of the holding jig 11 can be suppressed.

[0032] The core subset device 10 includes a forward and backward movement mechanism 14 that moves the holding jig 11 along the X direction. For this reason, the rotation radius of the holding jig 11 can be shortened, so that the distance between the upper mold and the lower mold M can be minimized. As a result, the stroke of the upper mold and the lower mold M becomes shorter, so that the time required for mold alignment and the like can be shortened. Therefore, productivity is improved.

[0033] The forward and backward movement mechanism 14 moves the holding jig 11 along the X direction at a position P3 where the holding jig 11 is separated from the space S in the Y direction. For this reason, while the operator visually inspects the upper mold and the lower mold M, the holding jig 11 can be moved along the X direction in the adjacent space. Therefore, the cycle time is shortened and productivity is improved.

[0034] Although various exemplary embodiments have been described above, various omissions, substitutions, and changes may be made without being limited to the above-described exemplary embodiments.

[0035] In the embodiment, the core setting device 10 was exemplified, but the core subset device 10 may be used in addition to the molding system 100. The core subset device 10 may be used, for example, in a casting system including a casting machine, and cores may be set in a lower mold (drag) disposed opposite to an upper mold (cope).

[0036] (First Modification Example) The core setting device 10 may not include the forward and backward movement mechanism 14. In this case, the rotation radius of the holding jig 11 may be adjusted so as to be able to move between the position P1 and the position P6 by 180° rotation. Also, in this case, the operation method of the molding system 100 does not include the step of moving the holding jig 11 in the X direction by the above-described forward and backward movement mechanism 14. That is, after the holding jig 11 moves in the order of the position P1, the position P2, and the position P3, it waits at the position P3 until the visual inspection of the upper mold and the lower mold M by the operator is completed without moving to the position P4. Subsequently, the step of moving the holding jig 11 in the Y direction is performed. Thereby, the holding jig 11 moves from the position P3 to the position P2. Subsequently, the step of rotating the holding jig 11 90° in the positive direction is performed. Thereby, the holding jig 11 moves from the position P2 to the position P6. Subsequently, after setting the cores in the lower mold M in the same manner as in the embodiment, the step of rotating the holding jig 11 180° in the negative direction is performed. Thereby, the holding jig 11 moves from the position P6 to the position P1 as shown in FIG. 12. Thereafter, the molding system 100 may operate in the same manner as in the embodiment.

[0037] (Second Modification Example) The shaping system 100 may operate as follows. For example, the step of retracting the holding jig 11 from between the shaping machine 1 and the operator may not include the step of rotating the holding jig 11 by 90° in the forward direction. That is, in the step of retracting the holding jig 11 from between the shaping machine 1 and the operator, without rotating the holding jig 11, while keeping the holding surface 11a parallel to the horizontal direction (X direction and Y direction), the holding jig 11 may be moved from the position P1 in the -Y direction. While the holding jig 11 is retracted from between the shaping machine 1 and the operator to the adjacent space, the operator visually inspects the upper mold and the lower mold M before setting the core. Subsequently, the step of moving the holding jig 11 in the Y direction is performed. Thereby, the holding jig 11 moves from the adjacent space to the position P1. Subsequently, the step of moving the holding jig 11 from the position P1 in the X direction by the forward and backward movement mechanism 14 is performed. Thereby, the holding jig 11 approaches the shaping machine 1. Subsequently, the step of rotating the holding jig 11 by 180° instead of 90° in the forward direction is performed. Thereby, the holding jig 11 moves to the position P6. Thereafter, the shaping system 100 may operate in the same manner as in the embodiment. Note that the step of moving the holding jig 11 from the position P1 in the X direction by the forward and backward movement mechanism 14 is not essential and may not be performed.

[0038] (Third Modification Example) As described above, in the second modification example, the step of moving the holding jig 11 in the X direction by the forward and backward movement mechanism 14 is performed after the holding jig 11 has moved from the adjacent space to the position P1. In contrast, in the third modification example, the step of moving the holding jig 11 in the X direction by the forward and backward movement mechanism 14 is performed while the holding jig 11 is retracted from between the operator and the shaping machine 1 to the adjacent space. In the third modification example, while the operator is visually inspecting the upper mold and the lower mold M, the holding jig 11 can be moved in the X direction in the adjacent space, so the cycle time is shortened and the productivity is improved. The third modification example is equivalent to the second modification example in other respects.

[0039] (Fourth Modification Example) The shaping system 100 may operate as follows. For example, the step of retracting the holding jig 11 from between the shaping machine 1 and the operator may not include the step of rotating the holding jig 11 90° in the positive direction. That is, in the step of retracting the holding jig 11 from between the shaping machine 1 and the operator, the holding jig 11 may be moved from position P1 in the -Y direction while keeping the holding surface 11a parallel to the horizontal directions (X direction and Y direction) without rotating the holding jig 11. Subsequently, in the adjacent space, the step of rotating the holding jig 11 90° in the positive direction is performed. As a result, the holding jig 11 moves to position P3. Subsequently, in the adjacent space, the step of moving the holding jig 11 in the X direction by the forward and backward movement mechanism 14 is performed. As a result, the holding jig 11 moves from position P3 to position P4. While the holding jig 11 is retracted from between the shaping machine 1 and the operator to the adjacent space, the operator visually inspects the upper mold and the lower mold M before setting the core.

[0040] Subsequently, the step of moving the holding jig 11 in the Y direction from the adjacent space is performed. As a result, the holding jig 11 moves from position P4 to position P5. Subsequently, the step of rotating the holding jig 11 90° in the positive direction is performed. As a result, the holding jig 11 moves from position P5 to position P6. The holding surface 11a faces the upper surface Ma of the lower mold M in the Z direction. Thereafter, the shaping system 100 may operate in the same manner as in the embodiment. Note that the step of moving the holding jig 11 in the X direction by the forward and backward movement mechanism 14 is not essential and may not be performed. Also, in the adjacent space, the step of rotating the holding jig 11 90° in the positive direction and the step of moving the holding jig 11 in the X direction may be performed in the reverse order.

[0041] (Fifth Modification Example) In the embodiment, the working position of the operator is provided in the front space, but the working position may be provided in an adjacent space, for example. In this case, in the initial state of the molding system 100, the holding jig 11 is not at the position P1 in the front space, but at a position in the adjacent space, which is adjacent to the working position of the operator in the X direction. With the holding jig 11 arranged at this position, the operator causes the core to be held by the holding jig 11. Subsequently, the operator moves from the adjacent space to the front space and visually inspects the upper mold and the lower mold M before setting the core. Subsequently, the operator moves outside the movable range of the core setting device 10.

[0042] Subsequently, a step of moving the holding jig 11 in the Y direction is performed. As a result, the holding jig 11 moves from the adjacent space to the position P1. This step is performed with no operator outside the movable range of the core setting device 10. For example, the push button for operating the core setting device 10 is provided outside the movable range of the core setting device 10. In addition, the core setting device 10 is configured to operate after confirming with an area sensor or the like that there is no operator outside the movable range of the core setting device 10.

[0043] Subsequently, in the front space, a step of rotating the holding jig 11 180° in the positive direction is performed. As a result, the holding jig 11 moves to the position P6. Thereafter, the molding system 100 may operate in the same manner as in the embodiment. Note that, between the step of moving the holding jig 11 in the Y direction and the step of rotating the holding jig 11 180° in the positive direction, a step of moving the holding jig 11 in the X direction from the position P1 by the back-and-forth movement mechanism 14 may be performed. Also, before the step of moving the holding jig 11 in the Y direction, a step of moving the holding jig 11 in the X direction by the back-and-forth movement mechanism 14 may be performed in the adjacent space.

[0044] (Sixth Modification Example) As described above, in the fifth modification, the step of rotating the holding jig 11 by 180° in the positive direction in the front space is performed. On the other hand, in the sixth modification, the step of rotating the holding jig 11 by 90° in the positive direction in the adjacent space and the step of rotating the holding jig 11 by 90° in the positive direction in the front space are performed. The sixth modification is equivalent to the fifth modification in other respects. In the sixth modification, while the operator is visually inspecting the upper mold and the lower mold M, the step of rotating the holding jig 11 by 90° in the positive direction in the adjacent space is performed. As a result, the holding jig 11 moves to the position P4. Subsequently, the operator moves outside the movable range of the core setting device 10.

[0045] Subsequently, the step of moving the holding jig 11 in the Y direction is performed. As a result, the holding jig 11 moves from the adjacent space to the position P5. This step is performed by the same interlock control as in the fifth modification in a state where there is no operator outside the movable range of the core setting device 10. Subsequently, in the front space, the step of rotating the holding jig 11 by 90° in the positive direction is performed. As a result, the holding jig 11 moves from the position P5 to the position P6. Thereafter, the molding system 100 may operate in the same manner as in the embodiment.

[0046] [Summary of Embodiments of the Present Disclosure] The present disclosure includes the following aspects.

[0047] (Clause 1) A core setting device according to an aspect of the present disclosure is a core setting device that sets cores in a lower mold disposed opposite to an upper mold in the vertical direction, and includes a holding jig having a holding surface for holding the cores, a rotation mechanism having a rotation axis parallel to a first direction orthogonal to the vertical direction and rotationally driving the holding jig, and a first moving mechanism for moving the holding jig along the first direction outside the space between the upper mold and the lower mold. The holding jig moves between outside the space and a core setting position where the holding surface faces the upper surface of the lower mold in the vertical direction by rotating about the rotation axis.

[0048] In this insert set device, the holding jig moves between the outside of the space between the upper mold and the lower mold and the insert set position by rotating about the rotation axis. That is, the holding jig can move between the outside of the above space and the insert set position inside the above space only by rotational movement. Since the holding jig can be moved efficiently in this way to set the inserts, it can contribute to shortening the cycle time. Further, in this insert set device, since the holding jig can be moved to a position separated from the upper mold and the lower mold, an operator can easily perform visual inspection of the upper mold and the lower mold. Therefore, the workability of the operator can be improved. Furthermore, the holding jig does not need to rotate 180° in the front space between the upper and lower molds. In the front space between the upper and lower molds, there may be provided a work position where an operator sets the inserts in the insert holding means or visually inspects the lower mold and the upper mold. Even in this case, since the operating range of the insert set device in the front space between the upper and lower molds can be made as narrow as possible, the workability of the operator can be further improved.

[0049] (Article 2) In the insert set device according to Article 2, the holding jig may move along the first direction by the first moving mechanism in a state where the holding surface is arranged parallel to the vertical direction. In this case, if the thickness of the holding jig is smaller than the size of the holding surface, the space required for the movement of the holding jig can be suppressed as compared with the case of moving the holding jig with the holding surface facing the vertical direction.

[0050] (Article 3) The insert set device according to Article 1 or 2 may further include a second moving mechanism that moves the holding jig along a second direction orthogonal to the vertical direction and the first direction. In this case, since the rotation radius of the holding jig can be shortened, the distance between the upper mold and the lower mold can be minimized. As a result, the strokes of the upper mold and the lower mold are shortened, so that the time required for mold alignment and the like can be shortened. Therefore, productivity is improved.

[0051] (Article 4) In the core subset device according to Item 3, the second moving mechanism may move the holding jig along the second direction at a position where the holding jig is separated from the space in the first direction. In this case, the holding jig can be moved along the second direction while an operator visually inspects the upper mold and the lower mold. Therefore, the cycle time is shortened and the productivity is improved.
