Description

1 Specifications A connector that allows multiple cores to be joined together. Technical Area The invention applies to all foundries using wet sand molding technology and resin-coated sand molding technology. 5 used to create the internal cavity or the external inverted angle shape of one or more parts. It relates to the connecting element that allows the cores to be assembled together. Previous technique In the casting industry, cores can be placed into molds one by one, or they can be shaped before being placed into the mold. They may also need to be assembled together. In fact, sometimes this becomes a necessity. The cores are assembled using different methods. These involve various chemical and refractory-based 10 Adhesives may be used. If the cores are not suitable for adhesive use or if their location... Consequently, the gases released from these adhesives during casting cannot be expelled from the system. In that case, the cores are then joined together by screwing or with iron bolt studs. They can be combined. Therefore, the new system that will be recommended for use in combining matches. In many cases, problems with gas voids forming in the part due to the adhesive used in the core are also a concern. That will be the solution. If the match assembly is to be done with chemical-based adhesive; the chemical to be used will be the one doing the job. It cannot be used in equal amounts by the staff in the match merging operation. Staff, If an automatic dosing system is not being used, it means it is being done by eye. This can lead to problems later on. Gas void in the casting due to excessive use of chemical-based core adhesive 20 This can cause problems. Also, if too little core adhesive is used, the cores will not adhere tightly to each other. They don't stick together properly, and the cores separate during production, leading to dimensional problems in the part. It may appear that there is too much and the part may have to be discarded. If it overflows, it enters the wall allowance of the part and also creates a notch on the flat surface of the part. This can cause the part to become defective. Using too much glue can damage the core. during the drying process, the core adhesive did not dry sufficiently, and during production, the metal... Contact with it can also cause an explosion, resulting in the formation of surface-damaged, scrap-like particles on the part. 2 Another method involves fastening two cores together using both adhesive and screws. This is done so that if the screw loosens due to lack of grip in the sand, the adhesive will activate. It is the assembly method. Core assembly may not be possible solely with iron connections or adhesive. Some special cores... Long screws are used to connect the cores, and the same 5 screws are applied to the places where these screws are installed. At the same time, adhesive can also be applied. When used alone, the screws are securely attached to the sand. They are unable to hold together properly, and the spades are able to detach from each other. Spade adhesive is used here. It holds the screws better to the sand. But ultimately, the core assembly time is extended and the work becomes more difficult. Efficiency is decreasing. Time is increasing, significantly impacting costs. The screw sizes used in this process are also very important. The amount of adhesive to be used and 10 The area of ​​application and the dosage of the adhesive are complementary factors. Another method is to use a nail gun to assemble the cores. This is done in foundries. Nailing is also performed in this way. This process is more common in cases with large geometries and thick walls. It is preferred in matches where there is no other material and it is also lightweight. In nailing applications, if the cores are heavy and there are 15 cores on a table... If it is to be positioned and also inverted and placed in the mold, then adhesive is also needed. is used. Such process designs are sometimes required in core and part designs. She can give birth. In this case, a waiting period is needed to allow the adhesive to solidify. This Waiting time prevents the product from being shipped to production without delay. Many matches have 20 In the foundry environment, they need to be left for a long time on pallets. This results in time and cost. That's what it means. However, the aim in production is to transform a raw material into a marketable product as quickly as possible. It is about transformation. Otherwise, capital sitting idle results in money loss and decreased productivity. Another method of joining the cores is by screwing them together. This process is done manually. That is... Personnel used a hand brake 25 to assemble the screw, whose length, diameter, and type were determined beforehand, into the core filled with sand. or it is installed in place using a torque wrench. Here, the employee's need for extreme caution and adherence to rules is highlighted. The employee handles the screw properly. not placing the team in the desired position, at the desired altitude, or near or far from the defined area However, during the painting and baking process, the core may flex or open up while being rotated with the tools, or even... 3 This will also cause cracking in the area. In summary, the work done is entirely dependent on the personnel and the job. The quality depends on the manual dexterity of the staff. Disclosure of the Invention The aim of the invention is to enable the clip described in the invention to be used much earlier and in 5 years compared to current applications in the art. Its advantage is that it enables quick assembly. The other purpose of the invention is to allow cores to be bonded, either unpainted or painted, after chemical-based bonding. without waiting in the drying oven or hot air heated drying chambers The goal is to ensure the shipment of the products to the molding lines for production. Another purpose of the invention is to connect studs, which are iron pieces with threads on one or both ends, to washers and 10 There is no need for the significantly high costs associated with core joining methods using nuts. It is about not staying. In the new spade assembly design, two or more spades are assembled using a clip, existing Unlike in technical aspects, there will be no missing elements; production will start quickly after the cores lock together. The goal is to ensure the transfer. Also, match merging is used in significant quantities in match merging. 15 iron, its processing, and subsequently its collection and formation within the system. The goal is to eliminate problems (such as sand conveyor belt tears). Another purpose of the invention is to avoid the problems experienced in the current technology by using a clip. The joining of the cores ensures that the product is cast without delay, in addition to the assembly work. It is to help quickly deliver it. 20 Another aim of the invention is to overcome the shortcomings of the existing technology in the assembly area with the help of clips. It is the elimination of. This will also prevent differential treatment of personnel or among personnel. A person's... The differences in work performance throughout the day and among personnel will be eliminated. The process involves a type of joining that anyone can do, achieved with the help of a joining clip. 25 Figures that will help understand the invention. Figure 1 shows a cross-sectional view including the connecting element positioned on the core body. 4 Figure 2 shows a separate view of the clip, also known as a connecting element. Figure 3 shows a cross-sectional view of the core being attached to the upper mold with a clip fastener.

It is illustrated. 15 The invention in question applies to all types of wet sand molding technology and resin-coated sand molding technology. in foundries, one or more parts, their internal cavity or external reverse angled shape The connecting element (200) that enables the assembly of the core body (100) used in the formation It is shown that the mentioned match bodies (100) can be connected quickly and easily. It contains a male connector (201) and a female connector (202) that provide. 20 The connecting element in question (200) has a retaining body (203) and at least two flexible ends (204). male connector (201) and female connector into which the aforementioned flexible ends (204) are placed It contains a slot (205) created in element (202). The connecting element (200) that is the subject of the invention was developed much earlier than applications in the current art. and it enables quick joining. Also, with the presence of the connecting element (200), two or in the assembly of more than one core, there will be no missing elements as in the current technique, A structure emerges where, after the cores lock together, production is quickly initiated. will be installed. The fastener in question (200) is made of plastic, plastic derivative, metal and different composites. It contains materials. In Figure-3; Clip connection of the core body (100) to the upper mold without using the wiring method. The cross-sectional view of the clip connection element (200) with which it is suspended is illustrated. The keycore spade, once placed and molded onto the hanging spade model, will be clipped to the spade for hanging. By inserting the keycore into the core, the combination is complete. In the current technique, the core is placed into the mold by means of a thin, tinned, "L"-shaped wire. This is achieved by attaching the cores to the upper mold. Workers on the molding line attach the cores to the mold. The personnel responsible for placement position the core in the appropriate place on the upper mold and secure it with L-shaped wires. They are attached at a certain angle from the sides. Damage to the mold during the wiring of the core to the upper mold. It should not be visible, otherwise sand particles will fall into the mold cavity and the sand void in the part will be 15. Discarding may occur. Also, if not properly attached, the cores may fall down during casting. This causes the part to sag incorrectly, resulting in it failing to meet the dimensional requirements. Without using the wiring method, the core body (100) is connected to the upper mold with a clip connection element (200); The negative situations described above are eliminated. The position of the match in the lower mold is 20 a structure will be created that will ensure the match doesn't float and that dimensional stability is achieved. is placed.
