Description

1 TARIFF Automatic positioning system Technical Area 5 The invention relates to a positioning system used in the molding of plastic parts. The invention specifically relates to molding production from polyurethane (PU) or similar plastic materials. During this process, there is no need to use a core for reverse-angled inserts (connectors). 10 with an automatic positioning system that allows it to be placed inside the mold without slipping It is related. State of the Art In plastic injection and molding technologies, especially with polyurethane (PU) and similar materials. During production with thermoplastic materials, inverted angled inserts are placed inside the mold. Installation is a common need. For this purpose, known techniques are usually mobile. Match systems are used. In current manual core systems, the core is moved manually by the operator. Cores are used. Although these cores are simple in structure, they shorten the production time. It is prone to lengthening and operator errors. Furthermore, manual core systems are prone to serial production. Not suitable for production. Mechanical core systems use mechanical cores that work in sync with die movements. These are the mechanisms. They complicate mold design, maintenance and adjustment. This is required. Also, due to tolerance errors, insert positioning... Deviations may occur. In hydraulic / pneumatic core systems, cores operate using pressurized fluid or air. They provide automatic movement. However, these spades are expensive and complex. It requires control systems. Due to leakage and wear problems, it is difficult to maintain the same level of service. Quality decreases over time. 35 2 In known techniques, the core is used for placing reverse-angled inserts into the mold. systems have significant limitations in terms of cost, complexity, cycle time, and quality. It carries. Therefore, in the current state of the art, it is more advanced than existing systems. A need arose for a compact, low-cost, fast, and reliable solution. In the literature review, an example of the current state of the technique is given. Document number CN203267101 can be shown. In the aforementioned document, the inserts... mechanical parts integrated into the mold body to ensure the mold holds the device in the correct position inside the mold. A positioning structure is described. The system positions the insert within the mold cavity. mechanical elements that enable fixation and their mold movements 10 It is based on synchronized operation. The structure used in the aforementioned document, only inserts located on the same axis as the mold working axis It can be used in positioning. The mold remains at an angle opposite to the working direction. It is not used in the positioning of inserts. Automatic positioning system Its purpose is to attach the inserts, which are located at an angle opposite to the mold's working axis, to the movable core system. The aim is to ensure insert positioning in a simple and effective way without the need for further intervention. In this system, as mentioned in the previous document, the mechanical positioning structure is the mold. This makes the design more complex and increases production costs. Furthermore, In the long term, due to tolerance errors and wear problems of moving parts Correct insert positioning becomes difficult, leading to deviations in product quality. 20 In addition, the system's maintenance and adjustment requirements affect the production process. It slows things down and reduces efficiency. Therefore, the statement in question in the document... due to the limitations of the structure such as high cost, complexity and quality problems It is not possible to provide the desired efficiency in industrial applications. In conclusion, the existence of the above problems and the inadequacy of the current solutions, This has made it necessary to make improvements in the technical field.

Figures 1a and 1b show cross-sectional views of the automatic positioning system that is the subject of the invention. 30 It is given. Accordingly, the automatic positioning system in its most basic form is; mold (K) The body (10) placed inside, the linearly moving inside the body (10) and The insert (connector) moves forward with the air supplied into the body (10) (I) pin (20) which ensures that it is held in the correct position, pin (20) which is located on the pin and pin (20) spring that moves the pin (20) in the backward direction by applying a backward pushing force 35 (30) connected to the end of the fuselage (10) by means of the air record (40) and inside the fuselage (10) The air hose (50) which provides compressed air is located on the pin (20) and It contains an O-ring (60) which ensures airtightness. The automatic positioning system described in this invention is made of polyurethane (PU) or similar plastic. 5 for using the movable core of the reverse angled insert (connector) (I) in the molds (K). It allows for positioning without the need for any additional effort. In the automatic positioning system subject to the invention, a tight fit into the mold (K) or A body (10) is inserted by means of screwing. Inside the body (10), at an inverted angle A pin (20) that ensures the insert (connector) (I) is held in the correct position 10 It has been placed. Pin (20) moves linearly back and forth inside the body (10). The pin (20) forward movement is provided by the air supplied into the body (10). Accordingly, an air hose (50) is attached to the end of the body (10). The aforementioned 15 The connection of the air hose (50) is the air fitting (40) which is connected to the end of the body (10) This is provided by. Compressed air supplied from the air hose (50) into the body (10). By means of the pin (20) moving forward inside the body (10) and as shown in figure 1b As seen, the insert (connector) fits into the hole located on (I). This ensures that the insert (connector) (I) is held in the correct position. 20 Pin (20) to ensure the airtightness of the air supplied into the shell (10) At least one O-ring (60) is fitted on it. The air inside the fuselage (10) is expelled. At least one air vent (11) on the fuselage (10) for evacuation It has been created. The backward movement of the pin (20) inside the body (10) is connected to the pin (20) This is provided by means of a spring (30). The spring (30) pushes the pin (20) backward. by applying a pushing force, the pin (20) is mechanically returned as shown in Figure 1a. It enables movement in that direction. The operating principle of the automatic positioning system described in this invention is as follows: 30 As shown in Figure 1a, in the initial position of the system, the pin (20) is connected by the spring (30). is held back. The air outlet hole (11) on the fuselage (10) is open, on the fuselage (10) The compartment in which the spring (30) is located is at atmospheric pressure. The pin (20) is inserted in this position. (connector) (I) is not in contact. This position is the passive state of the system. 35 And it is automatically regenerated in each cycle. 6 Compressed air during mold (K) closing or before mold (K) is closed, Air is conveyed through the air hose (50) to the air fitting (40). Air is then conveyed into the fuselage (10). It is directed. The O-ring (60) effectively prevents air from leaking into the system. It provides a seal. Due to this pressure effect, the pin (20) moves forward and the spring 5 (30) is compressed. When pin (20) moves forward as shown in Figure 1b, the insert (connection (I) inserts into the positioning hole located on the element (I) and insert (connecting element) (I) ensures that the pin (20) is fixed in the ideal position inside the mold (K) even if it is at an inverse angle. Thanks to the positioning function it provides, it is superior to traditional core mechanisms. The need has been completely eliminated. 10 Insert (connector) (I) is positioned thanks to the pin (20) for injection. It can be done. During injection, insert (connector) (I), pin (20) Thanks to this, he does not change his position. When the molding cycle is completed and the compressed air is cut off, the spring (30) engages. Push the pin (30) back again. The air outlet hole (11) releases the air trapped inside the housing (10). This allows the pin (20) to be ejected. Thus, the pin starts again as shown in Figure 1a. It returns to its previous position, which is its current position. This cycle repeats continuously, and This occurs in accordance with the high cycle speed. 20
