Problems solved by technology

[0002] In sand casting production, core casting is often used to form the inner cavity structure of the casting. In actual production, the core is shifted or the installation position is incorrect, which will easily cause under-casting and dimensional tolerance of the casting, resulting in a low pass rate of the casting and production. The cost is rising, and in the current production, most enterprises use experience to judge the installation position of the core, and lack effective detection devices and methods

Embodiment 1

[0024] like figure 1 , Figure 5 As shown, a method for detecting the installation position of the core in sand casting mainly includes the following steps:

[0025] A. First make a detection device according to the correct position of the main body core (9) in the lower box sand (8). The detection device is composed of a column (1) and a horizontal plate (2). The horizontal plate (2) is set on two columns ( 1) On the top, the distance between the two upright columns (1) is equal to the width of the lower sand box (8), and a detection part is provided on the horizontal plate (2). The top view orthographic drawing of the correct position in (8) is processed and produced. The height of the column (1) is equal to the top of the main body core (9) and the lower sand box when the main body core (9) is in the correct position in the lower sand box (8). (8) The distance between the upper planes of the side plates, the detection device is provided with a positioning and fixing part ...

Embodiment 2

[0033] like figure 1 , 2 , 3, 4, and 5, a method for detecting the installation position of the core in the sand casting of casing castings mainly includes the following steps:

[0034] A. First make a detection device according to the correct position of the main body core (9) in the lower box sand (8). The detection device is composed of a column (1) and a horizontal plate (2). The horizontal plate (2) is set on two columns ( 1) On the top, the distance between the two upright columns (1) is equal to the width of the lower sand box (8), and a detection part is provided on the horizontal plate (2). The top view orthographic drawing of the correct position in (8) is processed and produced. The height of the column (1) is equal to the top of the main body core (9) and the lower sand box when the main body core (9) is in the correct position in the lower sand box (8). (8) The distance between the upper planes of the side plates, the detection device is provided with a position...

Abstract

The invention discloses a detection method for a core installation position during sand casting. The method comprises the following steps: manufacturing a detection apparatus according to the correct position of a main body core in a lower sandbox, installing the main body core in the lower sandbox and clearing floating sand of the lower sandbox; and disposing the detection apparatus on the lower sandbox, fixing the detection apparatus with the lower sandbox by using a positioning fixed part and detecting the installation height and the installation planar angle of the core by using the detection apparatus. With the detection method provided by the invention, the possibility of occurrence of insufficient casting of castings and out-of-tolerance of a size is reduced, the qualified rate of a product is increased, the castings are allowed to have stable sizes and improved internal metallurgical quality, a casting period is effectively shortened, and production cost for the castings is saved.

Description

technical field [0001] The invention belongs to the technical field of sand casting, in particular to the detection of the installation position of a core in a sand box. Background technique [0002] In sand casting production, core casting is often used to form the inner cavity structure of the casting. In actual production, the core is shifted or the installation position is incorrect, which will easily cause under-casting and dimensional out-of-tolerance of the casting, resulting in a low pass rate of the casting and production. The cost is rising, and in the current production, most enterprises use experience to judge the installation position of the core, and lack effective detection devices and methods. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a method for detecting the installation position of the core in sand casting, which can realize the detection of the position of the core and is simple and conve...
