For example, it is possible to operate the operation panel 12 to select and use at least one mold 30 out of the eight molds 30 (30-1 to 30-8), and to mold thermosetting resin using only the selected mold 30.

[0016] A material supply device 20 is provided at the front of the upper portion of the device body 10. The material supply device 20 has a hopper section 21 that protrudes upward from the top surface of the device body 10. A thermosetting resin material supplied to the hopper section 21 by a belt conveyor (not shown) or the like is solidified into a predetermined shape such as a cylindrical shape by the material supply device 20, and is configured to be supplied to the material supply section 50 through a material supply flow path arranged inside the device body 10.

[0017] A product discharge port (not shown) is formed on the wall surface at the rear of the device main body 10. A belt conveyor (not shown) or the like is disposed in the product discharge port (not shown), and the product manufactured by molding the thermosetting resin by the thermosetting resin product manufacturing device 1 is configured to be discharged from the product discharge port (not shown) by the belt conveyor (not shown).

[0018] A pair of guide rails 13 are provided along the internal side walls of the device body 10. The guide rails 13 are provided along both of the opposing side walls, extending from the front to the rear of the side walls.

[0019] The molds 30 are disposed below the guide rails 13. The eight molds 30 (30-1 to 30-8) are arranged linearly along the pair of guide rails 13 in the direction in which the pair of guide rails 13 extends, with four molds on each side at predetermined intervals, separated into an odd-numbered row side (molds 30-1, 30-3, 30-5, 30-7) and an even-numbered row side (molds 30-2, 30-4, 30-6, 30-8).

[0020] Each of the molds 30 has an upper mold 311 and a lower mold 312. The upper mold 311 can move integrally with a slide table (not shown) that moves in the width direction of the device body 10 (the up and down direction in FIG. 3), and when the mold 30 is opened, it moves toward the inside of the device body 10 in the width direction of the device body 10 relative to the lower mold 312. An upper mold cleaner 313 is provided at the position to which the upper mold 311 has moved in this way. The upper mold cleaner 313 cleans the upper mold 311 that has moved in this way every time molding is performed by the mold and the mold 30 is opened, thereby removing burrs that are specific to hardening resin molding and debris generated by molding.

[0021] The guide rail 13 is provided with a work supply unit 40 and a material supply unit 50. The work supply unit 40 chucks and holds magnets of a rotor or stator that constitutes a motor, or an ECU to be installed in a vehicle, as work to be sealed with a thermosetting resin, and moves while being guided along the guide rail 13 to supply the work to the die 30.

[0022] 4 and 5, the work supply unit 40 has a chuck unit 41, a support unit 42, and a drive unit 43. The chuck unit 41 has a pair of openable and closable claws 411, and when the pair of claws 411 is opened, a work is placed between the pair of claws 411 and then closed to chuck the work.

[0023] The support portion 42 has columnar portions 421 and 423. A lower end of the columnar portion 421 is connected to an upper portion of the chuck portion 41, and an upper end of the columnar portion 421 is connected to an intermediate plate-shaped portion 422. The intermediate plate-shaped portion 422 is connected to a lower end of the columnar portion 423, and an upper end of the columnar portion 423 is connected to an upper plate-shaped portion 424.

[0024] The driving unit 43 has a driving part 431 having a cylinder. The driving part 431 is fixed to the guided plate-like part 432, and the lower part of a driving shaft 433 that drives integrally with a piston that slides inside the cylinder is connected to the upper plate-like part 424. When the piston is driven in the cylinder of the driving part 431, the driving shaft 433 is driven up and down, and the chuck part 41 and the support part 42 are configured to move up and down.

[0025] The material supplying section 50 chucks and holds the thermosetting resin material that has been solidified into a predetermined shape by the material supplying device 20 , moves while being guided along the guide rail 13 , and supplies it to the mold 30 .

[0026] More specifically, the material supply unit 50 has a material holding unit 51, a support unit 52, and a drive unit 53. The material holding unit 51 arranges and holds the thermosetting resin material. The support unit 52 has a plate-shaped unit 522. The material holding unit 51 is connected to the plate-shaped unit 522. The plate-shaped unit 522 is connected to a lower end of a columnar unit 523, and an upper end of the columnar unit 523 is connected to an upper plate-shaped unit 524.

[0027] The driving unit 53 has a driving part 531 having a cylinder. The driving part 531 is fixed to the guided plate-like part 432, and the lower part of a driving shaft 533 that drives integrally with a piston that slides inside the cylinder is connected to the upper plate-like part 524. When the piston is driven in the cylinder of the driving part 531, the driving shaft 533 is driven up and down, and the material holding part 51 and the support part 52 move up and down.

[0028] The guided plate-shaped portion 432 is supported slidably relative to the guide rail 13, and can be guided and moved along the guide rail 13. As a result, the guided plate-shaped portion 432 can be guided and moved along the guide rail 13 integrally with the chuck portion 41, the support portion 42, the drive portion 43, the material holding portion 51, the support portion 52, and the drive portion 53. In other words, the work supply portion 40 and the material supply portion 50 are connected together by the guided plate-shaped portion 432 and can be guided and moved along the guide rail 13 as an integral unit. In addition, the guided plate-shaped portion 432 is moved up and down by the drive portion 53, so that the work supply portion 40 and the material supply portion 50 are connected together by the guided plate-shaped portion 432 and can be moved in the up and down direction as an integral unit.

[0029] The guide rail 13 is also provided with a product removal section 60 and a cleaning section 70. The product removal section 60 chucks and holds a molded product, which is a workpiece molded in the mold 30 and sealed with a thermosetting resin, from the lower mold 312, which is a fixed mold when the mold 30 is in an open state, and moves while being guided along the guide rail 13, and places it on a belt conveyor (not shown) for carrying out the product from a product carrying-out port (not shown).

[0030] More specifically, the product removal section 60, like the work supply section 40, has a chuck section 61, a support section 62, and a drive section 63. The chuck section 61 has a pair of openable and closable claw sections 611, which open and close to place a molded product therebetween and then close the pair of claw sections 611 to chuck the molded product.

[0031] The support portion 62 has columnar portions 621 and 623. A lower end of the columnar portion 621 is connected to an upper portion of the chuck portion 61, and an upper end of the columnar portion 621 is connected to an intermediate plate-shaped portion 622. The intermediate plate-shaped portion 622 is connected to a lower end of the columnar portion 623, and an upper end of the columnar portion 623 is connected to an upper plate-shaped portion 624.

[0032] The driving unit 63 has a driving part 631 having a cylinder. The driving part 631 is fixed to the guided plate-like part 632, and the lower part of a driving shaft 633 that drives integrally with a piston that slides inside the cylinder is connected to the upper plate-like part 624. When the piston is driven in the cylinder of the driving part 631, the driving shaft 633 is driven up and down, and the chuck part 61 and the support part 62 are configured to move up and down.

[0033] The cleaning unit 70 cleans the lower die 312 and removes burrs and debris remaining on the lower die 312 every time the mold 30 is opened after molding and the molded product is removed. More specifically, the cleaning unit 70 has a cleaner unit 71, a support unit 72, and a drive unit 73. The cleaner unit 71 abuts against the lower die 312 and removes burrs and debris remaining on the lower die 312. The support unit 72 has a plate-shaped unit 722. The cleaner unit 71 is connected to the plate-shaped unit 722. The plate-shaped unit 722 is connected to a lower end of a columnar unit 723, and an upper end of the columnar unit 723 is connected to an upper plate-shaped unit 724.

[0034] The driving unit 73 has a driving part 731 having a cylinder. The driving part 731 is fixed to the guided plate-like part 632, and the lower part of a driving shaft 733 that drives integrally with a piston that slides inside the cylinder is connected to the upper plate-like part 724. When the piston is driven in the cylinder of the driving part 731, the driving shaft 733 is driven up and down, and the cleaner part 71 and the support part 72 are configured to move up and down.

[0035] The guided plate-shaped portion 632 is supported slidably relative to the guide rail 13, and can be guided and moved along the guide rail 13. As a result, the guided plate-shaped portion 632 can be moved integrally with the chuck portion 61, the support portion 62, the drive portion 63, the cleaner portion 71, the support portion 72, and the drive portion 73, while being guided along the guide rail 13. In other words, the product removal portion 60 and the cleaning portion 70 are connected together by the guided plate-shaped portion 632, and can be moved integrally while being guided along the guide rail 13. In addition, the guided plate-shaped portion 432 is moved up and down by the drive portion 53, and thus the product removal portion 60 and the cleaning portion 70 can be moved integrally in the up and down direction, while being connected together by the guided plate-shaped portion 432.

[0036] Next, the production of a molded product (product) by the thermosetting resin product manufacturing apparatus 1 having the above configuration will be described. First, the operation panel 12 of the device main body 10 is operated to set parameters, etc. As a result, one of the eight molds 30 (30-1 to 30-8) is selected, and the number of molded articles (products) to be molded by the selected mold 30, etc. are set.

[0037] Next, a thermosetting resin material is supplied to the hopper section 21 of the material supply device 20. As a result, the supplied thermosetting resin material is solidified into a predetermined shape such as a cylindrical shape by the material supply device 20. Then, the solidified thermosetting resin material is supplied to the material supply section 50 arranged at the position (initial position) of the front end of the guide rail 13 located at the front of the device body 10 through a material supply flow path (not shown) arranged inside the device body 10.

[0038] The chuck portion 41 of the work supplying portion 40 chucks and holds the work conveyed by a belt conveyor (not shown). Then, the material supplying portion 50 to which the thermosetting resin material has been supplied and the work supplying portion 40 holding the work move along the guide rail 13 while being integrally connected by the guided plate-shaped portion 432, and stop at a position above the mold 30 (e.g., the mold 30-1; hereinafter, the case where molding is performed in the mold 30-1 will be described as an example) selected by the operation panel 12. Then, the work supplying portion 40 and the material supplying portion 50 move down as one body, and the work supplying portion 40 places the work on the lower mold 312 of the mold 30-1, and the material supplying portion 50 supplies the thermosetting resin material to the lower mold 312. After that, the work supplying portion 40 and the material supplying portion 50 move up as one body.

[0039] Next, the upper die 311 is moved toward the lower die 312 together with a slide table (not shown) to close the die, and molding is performed in the die 30-1 to seal the work with thermosetting resin. During this time, the work supply unit 40 and the material supply unit 50, which are connected together by the guided plate-like portion 432, are returned to their initial positions, and the product removal unit 60 and the cleaning unit 70, which are connected together by the guided plate-like portion 632, are stopped at positions above the die 30-1 where molding has been completed.

[0040] Then, when molding in the mold 30-1 is completed, the upper mold 311 is moved away from the lower mold 312 together with a slide table (not shown) to open the mold. Next, the product removal unit 60 and the cleaning unit 70 descend together, and the chuck unit 61 of the product removal unit 60 chucks and holds the molded product as a product. The cleaner unit 71 of the cleaning unit 70 removes burrs and debris generated during molding from the lower mold 312 to clean it.

[0041] Thereafter, the product removal section 60 and the cleaning section 70 rise together and are guided by the guide rail 13 to the rear end position (unloading position) of the guide rail 13 located at the rear of the device body 10. Then, the chuck section 61 of the product removal section 60 places the molded product on a belt conveyor arranged at a product unloading port (not shown) on the wall surface at the rear of the device body 10. The molded product is then unloaded from the product unloading port (not shown) by the belt conveyor (not shown). This completes the manufacturing process for the molded product in one mold 30-1. Molding is similarly performed for the other molds 30 selected by the operation panel 12.

[0042] According to the thermosetting resin product manufacturing apparatus 1 according to this embodiment having the above-mentioned configuration, the following effects can be obtained.

[0043] The thermosetting resin product manufacturing apparatus 1 of this embodiment includes a plurality of molds 30, a work supply section 40 that supplies workpieces to the plurality of molds 30, a material supply section 50 that supplies thermosetting resin material to the plurality of molds 30, a product removal section 60 that removes products molded in the plurality of molds 30, and a cleaning section 70 that removes burrs generated in the plurality of molds 30.

[0044] This allows the molding of thermosetting resin using multiple dies 30, making it possible to efficiently mold and manufacture a large number of molded products. Also, it is possible to provide a thermosetting resin product manufacturing device 1 that can operate the required number of dies 30 to transport and mold materials and workpieces.

[0045] In addition, in the thermosetting resin product manufacturing apparatus 1 according to this embodiment, the multiple molds 30 are arranged in a straight line. This makes it possible to supply materials and workpieces to the mold 30, remove molded products from the mold 30, and clean the mold 30 by the straight line movement and the vertical movement. This makes it possible to improve molding efficiency and reduce the space required.

[0046] Furthermore, in the thermosetting resin product manufacturing apparatus 1 according to this embodiment, the work supply unit 40 and the material supply unit 50 are configured to be integrally movable in the direction in which the multiple dies 30 are arranged and in the vertical direction. This eliminates the need to separately control the work supply unit 40 and the material supply unit 50, making it possible to efficiently supply the work and the material.

[0047] Furthermore, in the thermosetting resin product manufacturing apparatus 1 according to this embodiment, the product removal section 60 and the cleaning section 70 are configured to be integrally movable in the direction in which the multiple molds 30 are arranged and in the vertical direction. This eliminates the need to separately control the product removal section 60 and the cleaning section 70, making it possible to efficiently remove the molded product and clean the lower mold 312 of the mold 30.

[0048] Moreover, in the thermosetting resin product manufacturing apparatus 1 according to this embodiment, at least one of the multiple molds 30 can be used to manufacture a thermosetting resin product. This makes it possible to select the number of molds 30 to be used appropriately, taking into consideration the time available for molding and the number of products to be formed, and makes it possible to manufacture a desired number of molded products in a desired time without using unnecessary molds 30. Furthermore, the use of multiple molds 30 can be selected, and thermosetting resin products can be manufactured according to the production volume and maintenance of the molds 30.

[0049] Furthermore, in the thermosetting resin product manufacturing apparatus 1 according to this embodiment, the multiple molds 30, the work supply section 40, the material supply section 50, the product removal section 60, and the cleaning section 70 are covered by the apparatus body 10, which serves as a cover member constituting the outer shell. This allows the thermosetting resin product manufacturing apparatus 1 to be compact, and allows it to be relatively easily relocated.

[0050] The present invention is not limited to the above-described embodiment, and modifications are possible within the technical scope described in the claims. For example, in the present embodiment, eight dies 30 are provided, but the present invention is not limited to this configuration, and it is sufficient that a plurality of dies are provided.
