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 is driven in the cylinder of the drive unit 731, the drive shaft 733 is driven up and down, and the cleaner portion 71 and the support portion 72 are configured to move up and down.

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 along the guide rail 13 as a single unit 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 can be moved along the guide rail 13 as a single unit connected by the guided plate-shaped portion 632. In addition, the guided plate-shaped portion 432 is moved up and down by the drive portion 53, so that the product removal portion 60 and the cleaning portion 70 can be moved up and down as a single unit connected by the guided plate-shaped portion 432.

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 products (products) to be molded by the selected mold 30, etc. are set.

Next, the 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 by the material supply device 20 into a predetermined shape, such as a cylindrical shape. The solidified thermosetting resin material is then supplied to the material supply section 50, which is located at the front end position (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.

The chuck section 41 of the work supply section 40 chucks and holds the work transported by a belt conveyor (not shown). Then, the material supply section 50 to which the thermosetting resin material has been supplied and the work supply section 40 holding the work are connected together by the guided plate-shaped section 432, and move along the guide rail 13 and stop at a position above the mold 30 (for example, mold 30-1; hereinafter, the case where molding is performed in mold 30-1 will be described as an example) selected by the operation panel 12. Then, the work supply section 40 and the material supply section 50 descend together, and the work supply section 40 places the work on the lower mold 312 of the mold 30-1, and the material supply section 50 supplies the thermosetting resin material to the lower mold 312. Then, the work supply section 40 and the material supply section 50 rise together.

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 workpiece 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 a position above the die 30-1 where molding has been completed.

Then, when molding in mold 30-1 is complete, 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. The cleaner unit 71 of the cleaning unit 70 removes burrs and debris generated during molding from the lower mold 312 to clean it.

The product removal section 60 and cleaning section 70 then rise together and move, guided by the guide rail 13, to the rear end position (discharge position) of the guide rail 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 on a belt conveyor arranged at a product discharge port (not shown) on the wall at the rear of the device main body 10. The molded product is then discharged from the product discharge 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 carried out for the other molds 30 selected by the operation panel 12.
