MEASUREMENT SYSTEM THAT ENSURES PARALLELISM CONTROL OF MOLDS IN CARD BOXES

Abstract

The invention is a measurement system that prevents the production of off-parallel cores and defective castings caused by the failure of the upper and lower molds to close parallel during core manufacturing in the iron casting industry. The system consists of a slot (6) created on the mold parting surface (4) where the upper (2) and lower (3) molds of the core box meet, and a measuring instrument (5) such as a caliper or gauge that allows data to be taken from this slot. The slot (6) structure provides reference surfaces that allow precise measurements in the X and Y axes when the molds are closed. By checking the numerical values ​​taken from the slot (6) during the stage when the molds are prepared for production or after they are connected to the presses, the production of cores with incorrect parallelism is prevented. In this way, a significant improvement is achieved in core and casting scrap rates; and production efficiency is increased by preventing losses of labor, raw materials and energy.

Description

1 TARIFF PARALLELISM CHECKING OF MOLDS IN CARD BOXES MEASUREMENT SYSTEM PROVIDING TECHNICAL FIELD The invention relates to the iron casting industry and core manufacturing, and to the lower and upper parts in core production. off-production problems caused by molds not closing parallel to each other 10 that eliminates the need for molds in the stages where they are prepared for production and attached to the presses. It relates to a measurement system that allows for parallelism verification. STATE OF THE ART In the iron casting industry, internal cavities and complex surface areas of cast parts 15 Using spades to create the details is one of the most basic production methods. The manufacturing process for these cores typically involves interlocking parts that determine the final form of the core. This is done through the use of a top mold and a bottom mold for the spade box. During the production process, these two molds are perfectly aligned along the mold parting surface. The core must be axially aligned and close with perfect parallelism, resulting in a core of 20. This is critically important in terms of dimensional accuracy and casting quality. In current technical applications, the closing of the mold parts that form the core boxes to directly check its accuracy and parallelism on the mold itself There is an integrated structure that allows for this. The molds attached to the core presses, 25 during operation due to vibrations or connection errors in the operational process It may remain open or the parallelism between the top and bottom of the mold may be disrupted. The main problems this situation creates are as follows: - The molds do not close perfectly parallel to each other, resulting in cores being axially misaligned by 30 degrees. This causes it to shift or become dimensionally non-standard. - Defective cores produced go unnoticed on the production line and during part casting. If used in this way, the resulting cast part will be dimensionally unsuitable. This leads to the final product being directly rejected. 2 - These scrap problems arise as a result of incorrect mold alignments; This leads to significant labor losses, raw material waste, and in foundries. Therefore, this leads to an uncontrolled increase in production costs. - In the current system, molds are prepared for production at the stage where they are placed in presses. A practical check to verify their parallelism after connection 5 The absence of a point of origin means that errors are only noticed after the product is received. This creates a technical loophole, leading to its failure. Ultimately, the problems mentioned above, which cannot be solved with current technology, are related. This has made it necessary to make an innovation in the technical field. 10 A BRIEF DESCRIPTION OF THE INVENTION The present invention eliminates the aforementioned disadvantages and the related technical Parallelism of molds in spade boxes to bring new advantages to the field 15 It is related to the measurement system that provides control. The main purpose of the invention is to ensure the parallelism of the upper and lower molds in spade boxes. by making the production of faulty products measurable and controllable before production begins. The key is to prevent it from the start. 20 Another aim of the invention is to determine the closing accuracy of molds with numerical data. By making it verifiable, we can reduce the number of rejected products and lower the costs of casting parts. It lowers it. Another purpose of the invention is to prevent casting parts from being discarded due to faulty cores. protecting raw materials and energy resources by preventing their separation to provide. Another objective of the invention is to prevent labor loss in the production line, thereby increasing the total tonnage of the facility to 30. The goal is to increase its capacity and profitability. Another aim of the invention is to integrate quality systems and continuous improvement processes, The goal is to establish an operator-independent and data-driven control mechanism. 3 The best way to utilize the advantages of the existing invention, together with its structure and additional elements. For understanding, it should be evaluated together with the figures explained below. is necessary.

It is explained with examples that will not create any limiting effect. The invention is iron 25 In the casting industry, checking the parallelism of molds in core manufacturing facilities. It is a measurement system developed for the purpose of; basically, the top mold of the spade box (2), The bottom mold of the matchbox (3), on the mold separation surface (4) where these two molds meet a socket (6) created and a measuring instrument (6) that enables data to be received from this socket (6) It consists of 30. Core box upper mold (2) and core box lower mold (3), in casting part production It is the basic part that forms the shape of the core (1) used. The contact of these two molds The region where it closes is defined as the mold separation surface (4). The basis of the invention 4 Its feature allows detailed measurement to be made on the mentioned mold parting surface (4). It is a socket (6) structure that gives a measurement such as caliper or gauge. The mentioned socket (6) is a measuring socket (6) structure such as caliper or gauge. The joining of the upper mold (2) and the lower mold (3) in such a way that the ends of the tools (5) can be placed It is structured in the form of a pocket from the edges inwards. The said slot (6) Its structure depends on the application requirements and mold geometry, for example 20 mm 5 with a depth and a total height of 40 mm when the molds are closed It is resizable. The geometric structure of the nest (6) is in both the X and Y axes when the molds are closed. Reference side walls (6.1) and reference 10 which allow for precise inspection. It offers base surfaces (6.2). Control in the x-axis (lateral slip) on the upper mold. (2) the vertical alignment of the socket side wall (6.1) and the socket side wall (6.1') in the bottom mold (3). This is ensured by checking. When there is a lateral misalignment between the molds, A step is formed between these vertical side walls (6.1) and the measuring instrument (5) is used to create this The difference can be determined numerically. The 15 on the Y-axis (parallelism / closure margin) The inspection is the vertical between the top surface (6.1) and the bottom surface (6.2) of the nest (6). This is achieved by measuring the distance. The molds do not close perfectly parallel. In this case, the vertical height of the housing deviates from the nominal value, and With the help of a caliper, this angular discrepancy is determined with millimeter precision. The system works as follows: When preparing the core molds for production, separation occurs. The measuring system is activated via the slot (6) on the surface (4). Upper mold (2) and With the lower mold (3) in the closed position, the measuring instrument (5) is used to measure the slot (6) on the X and Y axes. The values ​​are collected. Once the suitability of these collected values ​​is confirmed, the molds are put into production. is sent. After the molds are attached to the presses during the production phase, the connection is 25. A final check is performed from the socket (6) to re-check its sensitivity. Production begins when the measurement is within the specified tolerances. If an incorrect reading is received, the matchbox will be considered faulty and sent for maintenance. is directed. Thus, faulty cores (1) are included in the casting processes. It will be blocked. 30
