Description

1 Specifications DIMENSIONALLY LIMITED FLEXIBLE SUPPORT ELEMENT FOR CARD BOXES Technical Area The invention relates to the gap between cores in finished core figure assemblies in the iron casting industry. It relates to a dimensionally limited support element with a flexible structure for protection. 5 Previous technique In the iron casting industry, especially in cores without a core head or in long cores, the meat portions... Ensuring this is a critical issue. In such long cores, preventing the core from sagging inside the mold or the metal... using a support element to prevent the mold from breaking by lifting it while filling. It is of great importance. 10 Long cores carry a risk of sagging and fracture due to the long portion remaining inside the mold. This The risk directly affects casting quality and product integrity. Support elements ensure that the core is of this type. It prevents mechanical deformations, thus ensuring stability within the mold. In the current technique, to maintain the dimensional gap between the two cores, they are of a fixed height and capped. Special alloy support elements are used in this way. 15 These support elements are two pre-positioned cores with a core-to-core assembly completed. When it is intended to be placed between them, the measurement between the cores is fixed due to the pre-assembly process. For this reason, friction may occur on the core surfaces. As an alternative, flexible, hairpin-shaped screws are used. While support elements are practical in application, they also facilitate the transport and casting of the cores. During these processes, it is not possible to completely prevent the dimensional movement of the balls. 20 Fixed-size support elements cannot be inserted from the outside between the already assembled cores. If subjected to excessive force, superficial damage may occur to the cores, or the paint on the core surface may peel off. It can damage. While the hairpin-style flexible support element is practical in application, it is not suitable for any match. It is unable to show any resistance in maintaining the intermediate measure in its movement. 25 In this case, the hairpin-style flexible support element cannot prevent the movement of the core, so the final casting... This can lead to dimensional errors in the parts. 2 In the patent search conducted regarding the previous technique, patent number 2025 / 012097 registered in the name of DÖKTAŞ A.Ş. was found. Application number [number] refers to the production of cast iron without support elements for the cores. In the summary section; support element in core bodies without core heads in the iron casting industry. It is a structure that enables production without the aforementioned core body; its characteristic feature is this. By increasing the pressing surface area on the mold, the vertical-horizontal movement of the core is increased by 5 It is described as a structure that is blocked and includes core extensions that are integral to the core body. Disclosure of the Invention The aim of the invention is to create a new production method in this field, different from the production techniques used in the current technology. It is the introduction of a different supporting element that brings about a new approach. 10 The main objective of the invention is to create a flexible support element. Thus... The goal is to prevent unruly movements during the match by controlling the degree of closure. Another important objective of the invention is the flexibility of the support element, providing support between the two cores. The key is to ensure that no surface is damaged during the positioning of the element. One aim of the invention is to enable the cores to be transported through the casting process thanks to a flexible mechanism. It is about maintaining a tense position between the two matches. The area that limits the developed intermediate measure. However, during casting, possible core movements are controlled within the specified tolerance. is to be taken. The other purpose of the invention is to create a core assembly that is pre-assembled and has already been painted. The aim was to control the gaps between the cores without damaging the core surfaces. 20 Another aim of the invention is to overcome match movements that classic spring-loaded support elements cannot. It is restricted. Use in final assembled and painted core packages. that is intended. Another objective of the invention is to simultaneously produce castings with a flexible support element. Suitable for use in ensuring dimensional stability between the core and formwork sand during the process. 25 It contains a structure. 3 Figures that will help understand the invention. Figure 1 shows the positioning of the flexible support element located in the core cavity. Figure 2 shows a three-dimensional view of the flexible support element that is the subject of the invention.

Support positioned between each spade to maintain the spacing between (10,11) (12) 20 element (20) is illustrated. The support element in question (20) is located in the core cavity (12) and on the core seating surface (14) the positioned retaining surface (22) and the contact surface (13) of the mentioned upper core (10) are continuously 4 It includes a printing surface (21) that applies forced pressure. However, the aforementioned printing surface (21) An intermediate support element (23) is constructed between the retaining surface (22) and the support surface. The said retaining surface (22) and pressure surface (21) have a monolithic structure and are made of steel. It is a product. Support element (23); from the inner surface (24) of the support surface (22) to the pressure surface (21) 5 It is a monolithic structure extending in a straight cylindrical shape. Or, depending on preference, the inner (22) of the retaining surface. It is possible to fix it to the surface (24) by tight fitting or welding. Support element (23); In order for the support element (23) to provide the actual measurement, the limit measurement must be reached by stopping the stretching. It determines. On the other hand, the support element (20) has an extension extending at two different angles and a radiused surface (25) 10 It contains a printing surface (21). Due to the radius surface (25) and the solid structure The desired flexibility is achieved.
