It is a mold device. Effect of the Invention

[0008] According to the present invention, the slide unit is attached to the fixed unit or the movable unit in a state where it is not attached to the fixed body frame structure and the movable body frame structure. Therefore, even if the external dimensions or arrangement of the slide unit are changed, there is no need to replace the fixed body frame structure and the movable body frame structure. This allows the parts of the mold device to be reused efficiently. In addition, in the development of the mold device, the number of times the parts of the mold device are manufactured can be reduced, so that the manufacturing period of the mold device can be shortened and development costs can be reduced. Furthermore, the fixed unit protrudes toward the movable mold side from the fixed body frame structure, and the movable unit protrudes toward the fixed mold side from the movable body frame structure. Therefore, the setting of the slide unit is not restricted by the shapes of the fixed body frame structure and the movable body frame structure. [Brief description of the drawings]

[0010] A mold apparatus 10 according to an embodiment of the present invention will be described below with reference to the drawings. The mold apparatus 10 according to this embodiment is used, for example, for die casting to cast vehicle parts. The mold apparatus 10 may also be used for casting other than die casting, injection molding, blow molding, etc. Furthermore, molded products formed by the mold apparatus 10 are not limited to vehicle parts.

[0011] 1 and 2, a mold device 10 includes a movable mold 12, a plurality of slide units 14, and a fixed mold 16. The movable mold 12 is movable in a direction approaching the fixed mold 16 (in the direction of arrow A1) and in a direction moving away from the fixed mold 16 (in the direction of arrow A2).

[0012] 3, in the mold apparatus 10, in a mold closed state, a cavity space 22 is formed by the movable unit 26 of the movable mold 12, the multiple slide units 14, and the fixed unit 122 of the fixed mold 16. A molded product is formed by filling the cavity space 22 with molten material.

[0013] In this embodiment, the mold device 10 is configured by combining a plurality of parts consisting of dedicated parts, semi-general parts, and general-purpose parts. Dedicated parts are all parts that are affected by changes in the shape of the molded product (product). In other words, dedicated parts are parts that can be used only when molding a molded product of a certain model. In other words, dedicated parts are parts that need to be replaced when the external dimensions of the cavity space 22 are changed, for example.

[0014] A semi-general purpose part is a mold part that is standardized to accommodate multiple types of molded products. A semi-general purpose part does not need to be replaced when the outer dimensions of the cavity space 22 are changed within a certain range. In other words, a semi-general purpose part is a part that needs to be replaced when the outer dimensions of the cavity space 22 are changed beyond a certain range. For example, the size of the cavity space 22 changes depending on the size of the molded product, and parts such as the connecting bars 38, 132, etc. are standardized according to the size and applied to each size.

[0015] Generic parts are parts that can be reused in any molding process. The smaller the ratio of dedicated parts, the shorter the manufacturing time and the lower the manufacturing costs of the mold device 10 that may be required to change the design of the molded product.

[0016] 2 to 4, the movable mold 12 includes a movable main body frame structure 24 and a movable part unit 26. The movable main body frame structure 24 is a member for attaching the movable part unit 26 to a movable platen. As shown in FIGS. 1, 2, 4 and 5, the movable main body frame structure 24 has a plurality of cavity bases 36 and a plurality of connecting bars 38.

[0017] As shown in Figures 1, 4 and 5, the movable body frame structure 24 is formed in a polygonal ring shape. Specifically, the movable body frame structure 24 is formed in a roughly rectangular ring shape. A part of the movable part unit 26 is inserted into the inner hole 32 of the movable body frame structure 24 (see Figure 3). Also, an extrusion plate 34 for releasing the molded product from the movable part unit 26 is disposed in the inner hole 32 of the annular base part 28 (see Figure 1).

[0018] The cavity base 36 includes a plurality of cavity bases 36 and a plurality of connecting bars 38. The cavity bases 36 are general-purpose products, and the connecting bars 38 are semi-general-purpose products.

[0019] The cavity bases 36 form each corner of the movable main body frame structure 24. In this embodiment, the cavity bases 36 include four cavity bases 36. The cavity bases 36 are formed in a block shape (see FIG. 1). The cavity bases 36 are formed with insertion grooves 40 into which the ends of the connecting bars 38 are inserted (see FIGS. 1, 2, and 5). The cavity bases 36 have a surface 41 facing the fixed mold 16 (arrow A1 direction) with a recess 42 for supporting the movable unit 26 (see FIG. 3).

[0020] As shown in Figures 1 and 5, the connecting bars 38 form each side of the movable body frame structure 24. The connecting bars 38 connect adjacent cavity bases 36. The connecting bars 38 are, for example, rectangular column members. The connecting bars 38 may be cylindrical members or may be formed in a tubular shape. Each side of the movable body frame structure 24 may be formed by one connecting bar 38 or by multiple connecting bars 38.

[0021] The cavity base 36 is formed so that multiple types of connecting bars 38 with different lengths from one end to the other end (axial lengths) can be detachably attached. Therefore, the length of each side of the cavity base 36 can be easily changed by replacing the semi-generalized connecting bars 38 without replacing the general-purpose cavity base 36. The connecting bars 38 having an axial length corresponding to the external dimensions of the movable unit 26 are attached to the cavity base 36.

[0022] 2 and 4, each of the multiple cavity bases 36 is provided with a guide pin 30. The guide pin 30 is inserted into a guide bush 126 (described later) of the fixed mold 16. This allows the movable mold 12 to be accurately positioned with respect to the fixed mold 16 when the movable mold 12 is brought close to the fixed mold 16. The guide pin 30 and the guide bush 126 form a guide portion.

[0023] The guide pin 30 is a general-purpose product. The guide pin 30 may be detachable from the cavity base 36, or may be fixed to the cavity base 36 so as not to be detachable. The guide pin 30 protrudes from the cavity base 36 toward the fixed mold 16 (in the direction of the arrow A1) (see FIG. 2). The guide pin 30 is formed in a cylindrical shape. The guide pin 30 may be formed in a rectangular column shape or a cylindrical shape.

[0024] 4 and 6, the movable unit 26 is detachable from the movable body frame structure 24. The movable unit 26 has a movable cavity member 44, a flow diverter 46, a cavity back plate 48, and a cavity frame 50. The movable cavity member 44, the flow diverter 46, and the cavity back plate 48 are dedicated products, and the cavity frame 50 is a semi-general-purpose product.

[0025] A cavity surface 54 is formed on a surface 52a of the movable cavity member 44 facing the fixed mold 16 (in the direction of the arrow A1). As shown in Figs. 3 and 6, an outwardly protruding locking protrusion 56 is provided on the outer circumferential surface of the movable cavity member 44. The locking protrusion 56 extends in an annular shape so as to surround the movable cavity member 44 (see Fig. 6). The movable cavity member 44 is formed with a plurality of arrangement recesses 58 in which some of the plurality of slide units 14 are arranged. The diverter 46 is attached to the movable cavity member 44.

[0026] The cavity back plate 48 supports the movable cavity member 44. The cavity back plate 48 is formed in a flat plate shape. The back surface 52b of the movable cavity member 44 comes into contact with the cavity back plate 48. The planar dimensions of the cavity back plate 48 are larger than the planar dimensions of the back surface 52b of the movable cavity member 44. As shown in FIG. 3, the corners of the cavity back plate 48 are disposed in the recess 42 of the cavity base 36 of the movable body frame structure 24. The cavity back plate 48 comes into contact with the bottom surface 59 of the recess 42 of the cavity base 36.

[0027] As shown in Figs. 4 and 6, the cavity frame 50 is a member for attaching the movable cavity member 44 to the movable main body frame structure 24. The cavity frame 50 is formed in a polygonal ring shape so as to surround the movable cavity member 44. Specifically, the cavity frame 50 is formed in a roughly rectangular ring shape. A part of the movable cavity member 44 is inserted into an inner hole 60 of the cavity frame 50. As shown in Fig. 3, the corners of the cavity frame 50 are inserted into the recesses 42 of the cavity base 36. The cavity frame 50 is attached to the cavity base 36 of the movable main body frame structure 24 so that the locking protrusions 56 of the movable cavity member 44 are sandwiched between the cavity back plate 48 and the cavity frame 50.

[0028] As shown in Fig. 4 and Fig. 6, the multiple slide units 14 are detachable from the movable unit 26. Specifically, the multiple slide units 14 are detachable from the positions corresponding to the respective sides of the cavity frame 50. Note that, as shown in Fig. 2 and Fig. 3, the slide units 14 are not attached to a fixed main body frame structure 120 and a movable main body frame structure 24 of the fixed mold 16, which will be described later. Specifically, the slide units 14 are spaced apart from the fixed main body frame structure 120 and the movable main body frame structure 24. The multiple slide units 14 are configured similarly to one another.

[0029] As shown in FIGS. 3 and 7, the slide unit 14 includes a cylinder 62, a cylinder support portion 64, a slide core 66, a slide stopper 67, and a center key 68.

[0030] The cylinder 62 is a semi-general purpose product. The cylinder 62 is an actuator for moving the slide core 66 forward and backward. The cylinder 62 is, for example, a pneumatic cylinder driven by air pressure. The cylinder 62 may be an electric cylinder driven by electricity, or a hydraulic cylinder. The cylinder 62 has a cylinder body 70 and a cylinder rod 72 protruding from the cylinder body 70. A flange portion 74 (see FIG. 3) is provided at the tip of the cylinder rod 72.

[0031] The cylinder support part 64 is configured by combining a semi-general-purpose product and a general-purpose product. The cylinder support part 64 supports the cylinder 62 with respect to the movable unit 26. The cylinder support part 64 includes a base plate 76, a pair of reinforcing parts 78, a plurality of first support columns 80, and a plurality of second support columns 82. The base plate 76 is a semi-general-purpose product, and the reinforcing parts 78, the first support columns 80, and the second support columns 82 are general-purpose products. The base plate 76 is a part that is replaced depending on the external dimensions of the slide core 66.

[0032] The base plate 76 is formed in a flat plate shape. The base plate 76 is detachable from the end surface of the cylinder body 70. An insertion hole 84 (see FIG. 3) through which the cylinder rod 72 passes is formed in the base plate 76. The pair of reinforcing parts 78 are located on both sides of the insertion hole 84. The reinforcing parts 78 are formed in a U-shape. The ends of the U-shape of the reinforcing parts 78 are attached to the base plate 76 by fastening members 85 such as bolts (see FIG. 8). The reinforcing parts 78 are detachable from the base plate 76.

[0033] The first support 80 is a rectangular column member that can be attached to and detached from the reinforcing portion 78. In this embodiment, the multiple first support 80 are attached to the reinforcing portion 78 one by one. The first support 80 protrudes from the reinforcing portion 78 in the opposite direction to the cylinder body 70. An extension member (not shown) may be detachably attached to the tip of the first support 80. As shown in FIG. 8, a first insertion hole 87 extending along the axial direction is formed through the first support 80. A first fastening member 89 for attaching the first support 80 to the movable cavity member 44 is inserted into the first insertion hole 87. The first fastening member 89 is a bolt that can be screwed into a first locking hole 86 (screw hole) formed in the movable cavity member 44.

[0034] As shown in FIG. 3, FIG. 7, and FIG. 8, the second support column 82 is configured similarly to the first support column 80. The second support column 82 is attached to a corner of the base plate 76. The second support column 82 is adjacent to the reinforcing portion 78. In this embodiment, the cylinder support portion 64 has two second support columns 82. The axial length of the second support column 82 is longer than the axial length of the first support column 80. An extension member (not shown) can be attached to the tip of the second support column 82. As shown in FIG. 8, the second support column 82 is formed with a second insertion hole 91 extending along the axial direction. A second fastening member 93 for attaching the second support column 82 to the movable cavity member 44 is inserted into the second insertion hole 91. The second fastening member 93 is a bolt that can be screwed into a second locking hole 88 (threaded hole) formed in the movable cavity member 44.

[0035] The cylinder support portion 64 is removably held relative to the movable cavity member 44 by first fastening members 89 being screwed into the first locking holes 86 and by second fastening members 93 being screwed into the second locking holes 88 .

[0036] 3 and 7, the slide core 66 is a semi-general-purpose product. The slide core 66 is detachable from the tip of the cylinder rod 72. The slide core 66 is moved by the cylinder 62 in a direction intersecting the moving direction of the movable mold 12. Specifically, the slide core 66 is moved by the cylinder 62 in a direction perpendicular to the moving direction of the movable mold 12. The slide core 66 includes a core support portion 90, a core body 92, and a slide stopper 67.

[0037] The core support portion 90 includes a rod connection portion 94 and a holding portion 96. The rod connection portion 94 is formed in a block shape. The rod connection portion 94 is detachable from the tip portion of the cylinder rod 72. A connection recess 100 is formed in a base end surface 98 of the rod connection portion 94 facing the base plate 76, into which the tip portion of the cylinder rod 72 (a portion including the flange portion 74) can be inserted. The connection recess 100 opens in a T-shape on a side surface 102 in a direction perpendicular to the axial direction of the cylinder rod 72.

[0038] The holding portion 96 is provided on the tip surface of the rod connection portion 94. As shown in Fig. 3, the holding portion 96 protrudes further from the rod connection portion 94 on the opposite side to the movable main body frame structure 24 (in the direction of the arrow A1). A slide stopper 67 is attached to a surface 104 of the holding portion 96 facing the base plate 76. In the mold closed state, the slide stopper 67 comes into contact with a part of a fixed cavity member 138 (described later) that forms the fixed mold 16. This makes it possible to prevent the slide core 66 from retracting when a molding material is injected into the cavity space 22.

[0039] 3 and 7, the core body 92 is detachably attached to the tip surface of the holding portion 96. The core body 92 has a cavity surface 106 formed therein.

[0040] The center key 68 is a general-purpose product. The center key 68 is a component for guiding the slide core 66 in a linear direction. As shown in Fig. 3, a part of the center key 68 is inserted into a through hole 108 formed in the rod connection part 94. The other part of the center key 68 is inserted into a key hole 110 formed in the movable cavity member 44.

[0041] The slide unit 14 is attached to the movable cavity member 44 by the first fastening member 89 and the second fastening member 93 with one center key 68 inserted into the key hole 110 of the movable cavity member 44 and through the through hole 108 of the rod connection part 94. In this case, since only one center key 68 is required, the configuration of the slide unit 14 can be simplified.

[0042] In the slide unit 14 configured in this manner, when the size or the like of the molded product is changed, it can be accommodated by replacing the semi-generic products, the slide core 66, the base plate 76, and the cylinder 62, without replacing the generic products. In other words, when the size or the like of the molded product is changed, the generic products, the reinforcing part 78, the first support pillar 80, the second support pillar 82, and the center key 68, can be reused as they are without having to be newly manufactured.

[0043] In the movable mold 12, the movable unit 26 is detachable from the movable main body frame structure 24 with the multiple slide units 14 attached to the movable unit 26. In such a movable mold 12, the replacement work of the movable cavity member 44 and the diverter 46, which are dedicated parts, and the installation and removal work of the multiple slide units 14 are performed with the movable unit 26 removed from the movable main body frame structure 24. At this time, since the movable main body frame structure 24 does not get in the way of the replacement work and the installation and removal work, the replacement of the dedicated parts can be performed efficiently.

[0044] 1 to 3 and 9, the fixed mold 16 includes a fixed main body frame structure 120 and a fixed portion unit 122. The fixed main body frame structure 120 is a member for attaching the fixed portion unit 122 to a fixed platen.

[0045] As shown in Figures 9 and 10, the fixed body frame structure 120 is formed in a polygonal ring shape. Specifically, the fixed body frame structure 120 is formed in a roughly quadrangular ring shape. A part of the fixing unit 122 is inserted into an inner hole 128 of the fixed body frame structure 120 (see Figures 2 and 3).

[0046] The fixed body frame structure 120 is configured similarly to the movable body frame structure 24 described above. That is, the fixed body frame structure 120 has a plurality of cavity bases 130 and a plurality of connecting bars 132. The cavity bases 130 are general-purpose products, and the connecting bars 132 are semi-general-purpose products. The cavity bases 130 are formed with insertion grooves 134 (see Figs. 1 and 10) into which the connecting bars 132 are inserted, and recesses 136 (see Figs. 2 and 3) for supporting the fixed section units 122. A detailed description of the configurations of the cavity bases 130 and the connecting bars 132 will be omitted.

[0047] The cavity base 130 is formed so that multiple types of connecting bars 132 with different lengths from one end to the other end (axial lengths) can be detachably attached. Therefore, the length of each side of the fixed main body frame structure 120 can be easily changed by replacing the semi-generalized connecting bars 132 without replacing the general-purpose cavity base 130. The connecting bars 132 having an axial length corresponding to the external dimensions of the fixed portion unit 122 are attached to the cavity base 130.

[0048] Each of the multiple cavity bases 130 is provided with a guide bush 126. The guide bush 126 is a general-purpose product. The guide bush 126 may be detachable from the cavity base 130, or may be fixed to the cavity base 130 so as not to be detachable. The guide bush 126 protrudes from the cavity base 130 toward the movable mold 12 side (in the direction of arrow A2). The guide bush 126 is formed in a cylindrical shape.

[0049] 9, the fixed unit 122 is detachable from the fixed main body frame structure 120. The fixed unit 122 has a fixed cavity member 138, a sprue sleeve 140, a cavity back plate 142 (see FIG. 3), and a cavity frame 144. The fixed cavity member 138 is a dedicated product, while the sprue sleeve 140, the cavity back plate 142, and the cavity frame 144 are semi-general-purpose products.

[0050] A cavity surface 148 is formed on a surface 146a of the fixed cavity member 138 facing the movable mold 12 (in the direction of the arrow A2). As shown in FIG. 3, an outwardly protruding locking protrusion 150 is provided on the outer circumferential surface of the fixed cavity member 138. The locking protrusion 150 extends in an annular shape so as to surround the fixed cavity member 138. As shown in FIGS. 3 and 9, the fixed cavity member 138 is formed with an insertion recess 152 into which some of the multiple slide units 14 are inserted when the mold is closed. This makes it possible to prevent the slide units 14 and the fixed cavity member 138 from interfering with each other when the mold is closed.

[0051] As shown in FIG. 9, the sprue sleeve 140 is attached to the fixed cavity member 138. The sprue sleeve 140 is formed in an annular shape. In the mold closed state, the flow divider 46 is inserted into the sprue sleeve 140. The cavity back plate 142 and the cavity frame 144 are configured similarly to the cavity back plate 48 and the cavity frame 50 of the movable unit 26. Therefore, detailed configurations of the cavity back plate 142 and the cavity frame 144 will not be described. As shown in FIG. 3, the back surface 146b of the fixed cavity member 138 contacts the cavity back plate 142. The cavity frame 144 is attached to the cavity base 130 of the fixed body frame structure 120 so that the locking protrusion 150 of the fixed cavity member 138 is sandwiched between the cavity back plate 142 and the cavity frame 144.

[0052] In the fixed mold 16, the fixed cavity member 138, which is a dedicated part, is replaced with the fixed portion unit 122 removed from the fixed main body frame structure 120. At this time, the fixed main body frame structure 120 does not get in the way of the replacement work, so that the dedicated part can be replaced efficiently.

[0053] In this embodiment, the slide unit 14 is attached to the movable unit 26 without being attached to the fixed body frame structure 120 and the movable body frame structure 24. Therefore, even if the external dimensions or arrangement of the slide unit 14 are changed, there is no need to replace the fixed body frame structure 120 and the movable body frame structure 24. This allows the parts of the mold device 10 to be reused efficiently. In addition, in the development of the mold device 10, the number of times the parts of the mold device 10 are manufactured can be reduced, so that the manufacturing period of the mold device 10 can be shortened and development costs can be reduced. Furthermore, the fixed unit 122 protrudes toward the movable mold 12 side from the fixed body frame structure 120, and the movable unit 26 protrudes toward the fixed mold 16 side from the movable body frame structure 24. Therefore, the setting of the slide unit 14 is not restricted by the shapes of the fixed body frame structure 120 and the movable body frame structure 24.

[0054] This embodiment is not limited to the above-mentioned configuration. In the mold device 10, the guide pin 30 may be provided on the fixed body frame structure 120 and the guide bush 126 may be provided on the movable body frame structure 24. The slide unit 14 may be detachable from the fixed unit 122 instead of the movable unit 26.

[0055] [Inventions Obtained from the Embodiments] The invention that can be understood from the above embodiment will be described below.

[0056] One embodiment of the present invention is provided with a fixed mold (16) having a fixed main body frame structure (120) and a fixed unit (122) attached to the fixed main body frame structure (120), a movable mold (12) having a movable main body frame structure (24) and a movable unit (26) attached to the movable main body frame structure (24), and a slide unit (14) having a slide core (66) that moves in a direction intersecting with the moving direction of the movable mold (12), and in a mold closed state, Thus, a cavity space (22) is formed in the mold apparatus (10), the fixed unit (122) protrudes toward the movable mold (12) more than the fixed main body frame structure (120), the movable unit (26) protrudes toward the fixed mold (16) more than the movable main body frame structure (24), and the slide unit (14) is attached to the fixed unit (122) or the movable unit (26) in a state where it is not attached to the fixed main body frame structure (120) or the movable main body frame structure (24).

[0057] According to this configuration, the slide unit 14 is attached to the fixed unit 122 or the movable unit 26 without being attached to the fixed body frame structure 120 and the movable body frame structure 24. Therefore, even if the external dimensions or arrangement of the slide unit 14 are changed, there is no need to replace the fixed body frame structure 120 and the movable body frame structure 24. This allows the parts of the mold device 10 to be reused efficiently. In addition, in the development of the mold device 10, the number of times the parts of the mold device 10 are manufactured can be reduced, so that the manufacturing period of the mold device 10 can be shortened and development costs can be reduced. Furthermore, the fixed unit 122 protrudes toward the movable mold 12 from the fixed body frame structure 120, and the movable unit 26 protrudes toward the fixed mold 16 from the movable body frame structure 24. Therefore, the setting of the slide unit 14 is not restricted by the shapes of the fixed body frame structure 120 and the movable body frame structure 24.

[0058] In the above-mentioned mold apparatus (10), the slide unit (14) may be detachable from the movable unit (26), and the movable unit (26) may be detachable from the movable main body frame structure (24) with the slide unit (14) attached to the movable unit (26).

[0059] With this configuration, the slide unit (14) can be attached to and detached from the movable unit (26) efficiently.

[0060] In the above-mentioned mold apparatus (10), each of the fixed body frame structure (120) and the movable body frame structure (24) may be formed in a polygonal ring shape and may have a plurality of cavity bases (36, 130) forming corners of the polygon, and a plurality of connecting bars (38, 132) connecting the plurality of cavity bases (36, 130) to each other.

[0061] According to this configuration, the fixed body frame structure (120) and the movable body frame structure (24) can be simplified in structure.

[0062] In the above mold apparatus (10), each of the plurality of cavity bases (36, 130) may be formed so that a plurality of types of connecting bars (38, 132) having different axial lengths can be detachably attached thereto.

[0063] With this configuration, the lengths of the sides of the fixed body frame structure (120) and the movable body frame structure (24) can be easily changed by replacing the connecting bars (38, 132).

[0064] In the above-mentioned mold apparatus (10), each of the multiple cavity bases (36, 130) may be provided with a guide portion (30, 126) for positioning the movable mold (12) relative to the fixed mold (16) when the movable mold (12) is brought close to the fixed mold (16).

[0065] Such a configuration can increase the degree of freedom in the layout of the slide unit (14) relative to the movable unit (26) or the fixed unit (122).

[0066] In the above-mentioned mold apparatus (10), the slide unit (14) may be provided with a cylinder (62) for moving the slide core (66) back and forth, and the slide core (66) may be detachable from a cylinder rod (72) of the cylinder (62).

[0067] With this configuration, when the outer shape of the molded product is changed, the change can be accommodated by replacing the slide core 66. In other words, there is no need to replace the cylinder 62, which is economical.

[0068] The present invention is not limited to the above disclosure, and various configurations can be adopted without departing from the gist of the present invention. [Explanation of symbols]
