The piston is driven in the cylinder of the driving part 731, and the driving shaft 733 is driven up and down, and the cleaner part 71 and the support part 72 move up and down.

[0035] The guided plate-like portion 632 is supported to be able to slide relative to the guide rail 13, and can be guided and moved along the guide rail 13. Thus, the guided plate-like portion 632 can be guided and moved integrally along the guide rail 13 together with the clamping portion 61, the supporting portion 62, the driving portion 63, the cleaner portion 71, the supporting portion 72, and the driving portion 73. In other words, the product removal portion 60 and the cleaning portion 70 can be connected by the guided plate-like portion 632 and can be guided and moved integrally along the guide rail 13. In addition, the guided plate-like portion 432 is moved up and down by the driving portion 53, so that the product removal portion 60 and the cleaning portion 70 can be connected by the guided plate-like portion 432 and can be moved integrally in the vertical direction.

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

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

[0038] In addition, the clamping part 41 of the workpiece supply part 40 clamps and holds the workpiece conveyed by the conveyor belt (not shown). Then, the material supply part 50 supplied with the thermosetting resin material and the workpiece supply part 40 holding the workpiece move along the guide rail 13 while being connected as a whole by the guide plate-shaped part 432, and stop at a position on the upper side of the mold 30 (for example, the mold 30-1, hereinafter, the case of molding in the mold 30-1 is described as an example) selected by the operation panel 12. Then, the workpiece supply part 40 and the material supply part 50 are lowered as a whole, the workpiece supply part 40 arranges the workpiece on the lower mold 312 of the mold 30-1, and the material supply part 50 supplies the thermosetting resin material to the lower mold 312. Thereafter, the workpiece supply part 40 and the material supply part 50 are raised as a whole.

[0039] Next, the upper mold 311 and the slide table (not shown) are integrally moved toward the lower mold 312 to close the mold, and the workpiece is encapsulated with a thermosetting resin in the mold 30-1. During this period, the workpiece supply unit 40 and the material supply unit 50, which are integrally connected by the guide plate-shaped portion 432, are returned to the initial position, and the product removal unit 60 and the cleaning unit 70, which are integrally connected by the guide plate-shaped portion 632, are stopped at the upper side of the mold 30-1 after the molding is completed.

[0040] Then, when the molding of the mold 30-1 is completed, the upper mold 311 is separated from the lower mold 312 and moved together with the slide table (not shown) to open the mold. Next, the product removal unit 60 and the cleaning unit 70 are lowered together, and the clamping unit 61 of the product removal unit 60 clamps and holds the molded product as a product. In addition, the cleaner unit 71 of the cleaning unit 70 removes burrs and residues generated by molding from the lower mold 312 and cleans it.

[0041] After that, the product removal section 60 and the cleaning section 70 rise as a whole, and are guided by the guide rail 13 and move to the position (carry-out position) of the rear end portion of the guide rail 13 located at the rear of the device body 10. Then, the clamping section 61 of the product removal section 60 places the molded product as a product on a conveyor belt of a product carry-out port (not shown) arranged on the wall surface of the rear part of the device body 10. Then, the molded product is carried out from the product carry-out port (not shown) by the conveyor belt (not shown). The above is a manufacturing process of a molded product of a mold 30-1. The molding is performed in the same manner for other molds 30 selected through the operation panel 12.
