Description

Imprinting unit, molding device, molding system, management system, and imprinting method Technical Field Embodiments of the present invention relate to an imprint unit, a molding apparatus, a molding system, a management system, and an imprint method. Background In injection molding using a molding die, a molded article is molded in a cavity formed between a fixed die and a movable die. In addition, in the molded article molded as described above, any one of the date of manufacture, part information including the part ID, product information including the product ID, and the like may be imprinted as the imprint information. When the imprinting is necessary, an imprinting means capable of imprinting information on the molding die is mounted. Here, the imprinted information is generally different for each part and each product, and when the imprinted information includes date information, the nesting is changed to rewrite the information every time the date and time change. In view of ensuring traceability of the parts, it is necessary to reset the imprint information of the imprint unit imprint and update the imprint information to new imprint information every time a molded article is molded by one injection of injection molding. When the imprint unit is mounted on the molding die, it is required to be able to reset the imprint information imprinted by the imprint unit with a simple configuration. For example, it is required that the imprint information imprinted by the imprinting means can be easily reset without greatly changing the structure or the like from a mold in which the imprinting means is not mounted. Disclosure of Invention The invention provides an imprinting unit which is mounted on a forming die and can reset imprinted information with a simple structure. Further, a molding apparatus, a molding system, and a management system each including the imprint unit, and an imprint method using the imprint unit are provided. According to an embodiment, an imprint unit includes an imprint substrate, a plurality of imprint pins, and a reset pin. The imprinting substrate is disposed on a surface of the movable mold facing the fixed mold. The plurality of imprinting pins are respectively mounted on the imprinting substrate in a state of being movable relative to the imprinting substrate along the opening and closing direction of the movable mold, and are movable to an imprinting position and a non-imprinting position, wherein the imprinting position is a position capable of imprinting, and the non-imprinting position is a position movable from the imprinting position to a side opposite to the side where the fixed mold is located. The reset pin moves in conjunction with the movement of the pushing plate in the opening and closing direction of the movable die, and presses the plurality of imprinting pins toward the imprinting position by pressing the imprinting substrate from the side opposite to the side where the fixed die is located. According to the above-described imprint unit, it is possible to reset the imprinted information with a simple configuration while being mounted on the molding die. The molding apparatus, the molding system, and the management system further include the imprint means, and the imprint means is used for the imprint method.
