Description
Technical Field

[0002] In the production of static pressure molding line, the box closing machine is used to realize the automatic box closing of the upper sand box and the lower sand box. The existing box closing mechanism moves the lower sand box to the bottom of the upper sand box by a transfer trolley, and positions the upper and lower sand boxes by inserting the positioning cylinder through the guide holes of the upper and lower sand boxes, thereby realizing the positioning of the upper and lower sand boxes. However, after long-term use, the transfer trolley in the box closing machine cannot be accurately controlled in its moving position, which makes it easy for a small deviation to occur between the upper and lower sand boxes, and then leads to the failure to smoothly complete the box closing between the upper and lower sand boxes. The deviation between the positions of the two will destroy the overall structure of the molding sand body in the box, thereby causing production delays and flow process pauses. In addition, the positioning deviation problem is difficult to adjust through automated correction methods, which has a relatively large impact. Utility Model Content

Before the main hydraulic cylinder 1 is started, the external control system (not shown in the figure) will detect whether the infrared sensor 18 receives the reflection through the data of the control assembly 17.

[0020] The parts of this application involving circuits, electronic components and modules are all existing technologies and can be fully implemented by those skilled in the art. The content protected by this utility model does not involve improvements to software and methods.
[0021] As a preferred embodiment, the mounting plate 16 has a rectangular structure, and the two groups of guard plates 14 fixedly connected to the upper surface of the mounting plate 16 both have a rectangular structure. The cross-section formed by the combination of the mounting plate 16 and the guard plate 14 is a concave structure, and the through holes 15 opened in the guard plate 14 and the mounting plate 16 are both cylindrical structures.
[0022] In this embodiment, if Figure 2and Figure 3 At the edges of both ends of the guard plate 14, a bevel structure is formed, which can then assist in reducing the difficulty of moving the lower sand box 6 to the surface of the mounting plate 16. At the same time, the opening of the through hole 15 facilitates subsequent multi-positioning processing and improves the positioning accuracy of the static pressure line mold closing machine.
[0023] As a preferred embodiment, the positioning groove formed on the upper surface of the guard plate 14 is of a square structure. Two groups of positioning components 13 are fixedly connected in the positioning groove. Semi-circular through grooves are opened at the positions of the two groups of positioning components 13 relative to the through hole 15. At the same time, the positioning component 13 and the through groove are combined to form a concave-shaped structure, and the depth of the positioning groove is equal to the thickness of the positioning component 13.
[0024] In this embodiment, as shown in Figure 2 and Figure 3 , the setting of the two groups of positioning components 13 enables quick confirmation of the deviation cause of the lower sand box 6 when the position where the lower sand box 6 stops deviates, facilitating the transfer component 7 to adjust the transfer trolley to move forward or backward again, and improving the efficiency of positioning correction.
[0025] As a preferred embodiment, there are two groups of side plates 21 in the positioning component 13. Both groups of side plates 21 are of a long strip structure. The cross-section formed by combining the top plate 20, the side plates 21, and the bottom plate 23 is of a square structure. At the same time, the top plate 20 is made of an elastic material, while the bottom plate 23 is made of a hard material.
[0026] In this embodiment, as shown in Figure 3 and Figure 5 , the setting of the side plates 21 enables a corresponding gap to exist between the bottom plate 23 and the top plate 20, which can then ensure that the corresponding circuit of the positioning component 13 is in a normally open state. Moreover, since the top plate 20 is made of an elastic material, it can effectively enhance the deformation effect of the top plate 20 after being stressed, ensuring that the positioning component 13 can be smoothly connected under an external force.
[0027] As a preferred embodiment, a combined plate 22 is fixedly connected to the middle of the lower surface of the top plate 20, and two groups of broken plates 19 are fixedly connected to both ends of the upper surface of the bottom plate 23. The combined plate 22 and the broken plates 19 are distributed in a "冂" shape, and the length of the combined plate 22 is three times the length of the broken plates 19.
[0028] In this embodiment, as shown in Figure 3 and Figure 5 , both the combined plate 22 and the broken plates 19 are made of a conductive material. The two groups of broken plates 19 are respectively connected to the control component 17 through corresponding circuits. Then, when the combined plate 22 abuts against the two groups of broken plates 19, the corresponding circuit of the positioning component 13 can be smoothly connected. At the same time, the dimension setting between the combined plate 22 and the broken plates 19 can assist in enhancing the contact stability between the two.
[0029] As a preferred embodiment, the fixing plate 8 is in a rectangular structure. Two sets of receiving plates 9 are fixedly connected to both ends of the fixing plate 8, and both sets of receiving plates 9 are in a cuboid structure. The fixing plate 8 and the receiving plates 9 are combined to form a U-shaped structure. At the same time, the receiving groove opened at the lower end of the receiving plate 9 is in a cylindrical structure.
[0030] In this embodiment, as Figure 1 and Figure 2 , the setting of the fixing plate 8 enables the receiving plate 9 to be smoothly fixedly connected to the surface of the clamping plate 4, thereby ensuring that the clamping assembly 3 can have a corresponding positioning and correction effect during the box closing process, and avoiding the problem that the static pressure line shaped sand body in the box is damaged due to misaligned box closing.
[0031] As a preferred embodiment, the buffer rod 12 is in a cylindrical structure. The limiting groove opened in the middle of the buffer rod 12 is in a strip-shaped structure. Both sides of the receiving groove are fixedly connected to the positioning bolts 11 through through holes. The positioning bolts 11 are slidably connected in the limiting groove. At the same time, the reflecting block 24 fixedly connected to the lower surface of the buffer rod 12 is in a cylindrical structure. The lower surface of the reflecting block 24 is in a spherical groove structure, and the thickness of the reflecting block 24 is less than the depth of the corresponding groove.
[0032] In this embodiment, as Figure 4 , a reflective coating is applied in the groove of the reflecting block 24. Through the groove structure of the reflecting block 24, the receiving effect of the infrared sensor 18 on the reflected infrared rays can be enhanced, improving the accuracy of the positioning of this box closing machine. At the same time, the setting of the positioning bolts 11 can limit the moving range of the buffer rod 12 in the receiving groove, avoiding accidental dropping of the buffer rod 12.
[0033] The positioning mechanism of the static pressure line box closing machine of the present utility model, through the cooperation of the receiving plate 9, the buffer rod 12, the pressure sensor 10, the positioning assembly 13 and the infrared sensor 18, enables the box closing machine to perform corresponding multiple pre-positionings before the upper sand box 5 and the lower sand box 6 are closed, thereby facilitating timely judgment of whether the positions of the upper sand box 5 and the lower sand box 6 are deviated, further avoiding accidental damage to the static pressure line shaped sand body in the sand box, and also facilitating subsequent positioning and correction, reducing the production delay time.
