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

[0017] A product discharge port (not shown) is formed on the rear wall of the device main body 10. A belt conveyor (not shown) or the like is arranged in the product discharge port (not shown), and the products manufactured by molding thermosetting resin using the thermosetting resin product manufacturing device 1 are 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 side walls inside 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 arranged below the guide rails 13. The eight molds 30 (30-1 to 30-8) are arranged in a straight line 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 arranged at predetermined intervals, divided into odd-numbered rows (molds 30-1, 30-3, 30-5, 30-7) and even-numbered rows (molds 30-2, 30-4, 30-6, 30-8).

[0020] Each mold 30 has an upper mold 311 and a lower mold 312. The upper mold 311 is movable 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 moved upper mold 311 every time molding is performed using the mold and the mold 30 is opened, thereby removing burrs that are specific to molding a curable resin 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 the work to be sealed with thermosetting resin, such as the magnets of the rotor and stator that constitute a motor, or the ECU to be installed in a vehicle, and moves while being guided along the guide rail 13 to supply it to the mold 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 them and then the pair of claws 411 is closed to chuck the work.

[0023] The support part 42 has columnar parts 421 and 423. The lower end of the columnar part 421 is connected to the upper part of the chuck part 41, and the upper end of the columnar part 421 is connected to the intermediate plate part 422. The intermediate plate part 422 is connected to the lower end of the columnar part 423, and the upper end of the columnar part 423 is connected to the upper plate part 424.

[0024] The drive unit 43 has a drive part 431 with a cylinder. The drive part 431 is fixed to the guided plate-like part 432, and the lower part of a drive 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 in the cylinder of the drive part 431 is driven, the drive shaft 433 is driven up and down, and the chuck part 41 and the support part 42 move up and down.

[0025] The material supply unit 50 chucks and holds the thermosetting resin material that has been solidified into a predetermined shape by the material supply device 20 , and moves while being guided along the guide rails 13 to supply 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 the lower end of a columnar unit 523, and the upper end of the columnar unit 523 is connected to an upper plate-shaped unit 524.

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

[0028] The guided plate-shaped portion 432 is slidably supported on 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, support portion 42, drive portion 43, material holding portion 51, support portion 52, and drive portion 53. In other words, the work supply portion 40 and the material supply portion 50 are connected by the guided plate-shaped portion 432 and can be guided and moved integrally along the guide rail 13. Furthermore, by moving the guided plate-shaped portion 432 up and down by the drive portion 53, the work supply portion 40 and the material supply portion 50 can be connected by the guided plate-shaped portion 432 and can be moved integrally in the up and down direction.

[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 thermosetting resin, from the lower mold 312, which is a fixed mold when the mold 30 is in an open state, and moves the molded product while being guided along the guide rail 13, and places it on a belt conveyor (not shown) for removal from a product delivery port (not shown).

[0030] More specifically, the product removal unit 60 has a chuck unit 61, a support unit 62, and a drive unit 63, similar to the work supply unit 40. The chuck unit 61 has a pair of openable and closable claws 611, and when the pair of claws 611 opens, a molded product is placed between them and then the pair of claws 611 closes to chuck the molded product.

[0031] The support part 62 has pillar parts 621 and 623. The lower end of the pillar part 621 is connected to the upper part of the chuck part 61, and the upper end of the pillar part 621 is connected to an intermediate plate part 622. The intermediate plate part 622 is connected to the lower end of the pillar part 623, and the upper end of the pillar part 623 is connected to an upper plate part 624.

[0032] The drive unit 63 has a drive part 631 with a cylinder. The drive part 631 is fixed to the guided plate-like part 632, and the lower part of a drive 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 in the cylinder of the drive part 631 is driven, the drive shaft 633 is driven up and down, and the chuck part 61 and the support part 62 move up and down.

[0033] The cleaning unit 70 cleans the lower mold 312 and removes burrs and debris remaining on the lower mold 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 mold 312 and removes burrs and debris remaining on the lower mold 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 column-shaped unit 723, and the upper end of the column-shaped unit 723 is connected to an upper plate-shaped unit 724.

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

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

[0036] Next, we will explain the manufacturing of molded articles (products) using the thermosetting resin product manufacturing apparatus 1 configured as described above. First, the operation panel 12 of the apparatus main body 10 is operated to set parameters, etc. This allows one of the eight molds 30 (30-1 to 30-8) to be selected, and the number of molded articles (products) to be molded using the selected mold 30, etc., to be set.

[0037] Next, the thermosetting resin material is supplied to the hopper 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. The solidified thermosetting resin material is then supplied to the material supply unit 50, which is located at the front end (initial position) of the guide rail 13 located at the front of the device body 10, through a material supply flow path (not shown) located inside the device body 10.

[0038] The chuck portion 41 of the work supply unit 40 chucks and holds the workpiece transported by a belt conveyor (not shown). Then, the material supply unit 50 supplied with the thermosetting resin material and the work supply unit 40 holding the workpiece, connected together by the guided plate-shaped portion 432, move along the guide rail 13 and stop at a position above the mold 30 (e.g., mold 30-1; hereinafter, the case where molding is performed using mold 30-1 will be described as an example) selected on the operation panel 12. The work supply unit 40 and the material supply unit 50 then descend together, and the work supply unit 40 places the workpiece on the lower mold 312 of mold 30-1, and the material supply unit 50 supplies the thermosetting resin material to the lower mold 312. The work supply unit 40 and the material supply unit 50 then ascend together.

[0039] Next, the upper mold 311 is moved integrally with a slide table (not shown) toward the lower mold 312 to clamp the mold, and molding is performed in the mold 30-1 to seal the work with thermosetting resin. During this time, the work supply unit 40 and 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 cleaning unit 70, which are connected together by the guided plate-like portion 632, are stopped at positions above the mold 30-1 where molding has finished.

[0040] Then, when molding in mold 30-1 is completed, the upper mold 311 is moved together with a slide table (not shown) away from the lower mold 312 to open the mold. Next, the product removal unit 60 and cleaning unit 70 descend together, and the chuck unit 61 of the product removal unit 60 chucks and holds the molded 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 cleaning section 70 rise together and are guided by the guide rails 13 to the rear end position (unloading position) of the guide rails 13 located at the rear of the device main body 10. The chuck section 61 of the product removal section 60 then places the molded product onto a belt conveyor located at a product unloading port (not shown) on the wall at the rear of the device main 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 a molded product in one mold 30-1. Molding is similarly carried out for other molds 30 selected on the operation panel 12.

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

[0043] The thermosetting resin product manufacturing apparatus 1 according to 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 thermosetting resin to be molded using multiple molds 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 molds 30 to transport and mold materials and workpieces.

[0045] Furthermore, in the thermosetting resin product manufacturing apparatus 1 according to this embodiment, the multiple molds 30 are arranged in a straight line. This allows the supply of materials and workpieces to the molds 30, the removal of molded products from the molds 30, and cleaning of the molds 30 to be performed by this linear movement and by movement in the up and down directions. 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 as a single unit that can move in the direction in which the multiple molds 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 workpieces and materials.

[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 as a single unit that can move 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 molded products and clean the lower mold 312 of the mold 30.

[0048] Furthermore, the thermosetting resin product manufacturing apparatus 1 according to this embodiment can manufacture thermosetting resin products using at least one mold 30 out of the multiple molds 30. 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 the desired number of molded products in the desired time without using unnecessary molds 30. Furthermore, the use of multiple molds 30 can be selected, making it possible to manufacture thermosetting resin products 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 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 main body 10, which serves as a cover member that forms the outer shell. This allows the thermosetting resin product manufacturing apparatus 1 to be compact and relatively easy to relocate.

[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 this embodiment, eight molds 30 are provided, but the present invention is not limited to this configuration, and any number of molds may be provided. Furthermore, while the molds 30 are provided in pairs in two rows, the present invention is not limited to this arrangement.
