DETAILED DESCRIPTION

[0021] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0022] Example

[0023] See also Figure 1-4 , the utility model provides a technical solution: a casting core box structure;

[0024] The present invention aims to provide a casting core box structure that is conducive to the connection between the upper core box and the lower core box. The existing casting core boxes are connected by bolts, which is inconvenient to disassemble and assemble.

[0025] Based on the above problems, the components in this case include an upper core box 1 and a lower core box 2. The top of the upper core box 1 is plugged with the top of the lower core box 2. A connecting component is provided at the plugging point of the upper core box 1 and the lower core box 2. The connecting component includes:

[0026] A first limiting block 3, a second limiting block 4, a sliding frame 5, a rotating block 6, a connecting frame 7, a connecting portion and a first cushion block 8;

[0027] The first limit block 3 is installed at the front end of the upper core box 1, the second limit block 4 is installed at the front end of the lower core box 2, the rear side of the sliding frame 5 is slidably connected to the front end of the upper core box 1, the rotating block 6 is rotatably connected to the upper side of the sliding frame 5, the upper side of the connecting frame 7 is connected to the lower side of the rotating block 6, the connecting assembly is arranged at the lower side of the sliding frame 5, and the first cushion block 8 is installed on the inner side of the sliding frame 5;

[0028] The connecting part includes: two strip grooves 9, two sliding blocks 10, two connecting springs 11 and a pulling frame 12;

[0029] Two strip grooves 9 are provided on the front and rear sides of the sliding frame 5, two sliding blocks 10 are slidably connected to the two strip grooves 9, one end of two connecting springs 11 is connected to the inner wall of the strip groove 9, and the other end is connected to one side of the two sliding blocks 10, and one side of the pulling frame 12 is rotatably connected to the outer sides of the two sliding blocks 10;

[0030] It should be noted that, in the process of using the casting core box for casting, the upper core box 1 and the lower core box 2 are first plugged in, at which time the first limit block 3 and the second limit block 4 are in close contact, and then the operator moves the sliding frame 5 horizontally to move the sliding frame 5 to the first limit block 3 and the second limit block 4, and makes the first limit block 3 and the second limit block 4 side in close contact, and then rotates the rotating block 6, and drives the lower side of the connecting block to be in close contact with the lower side of the sliding frame 5. At this time, the operator moves the pulling frame 12 along the strip groove 9, so that one side of the pulling frame 12 is stuck on the lower side of the connecting frame 7. At this time, the pulling frame 12 will stretch the connecting spring 11 through the sliding block 10, and the reaction force generated by the stretching spring can increase the tightness of the connecting groove of the pulling frame 12 and the lower side of the connecting frame 7.

[0031] It should be emphasized that the rotating block 6 is hinged to the upper side of the sliding frame 5 through a large-angle hinge. When the upper core box 1 and the lower core box 2 need to be separated, the above process is repeated in reverse, and the rotating block 6 and the connecting frame 7 are reset. At this time, the connecting frame 7 will rotate 180 degrees and will not hinder the separation of the first limit block 3 and the second limit block 4.

[0032] Since there may be a gap between the connecting frame 7 and the first limiting block 3 and the second limiting block 4, the connection effect between the upper core box 1 and the lower core box 2 is affected. Therefore, a second cushion block 13 is provided inside the connecting frame 7 to increase the connection effect.

[0033] The surface of the sliding frame 5 is smooth, which is not convenient for the operator to move. A trapezoidal toggle block 14 is provided on the surface of the sliding frame 5 to facilitate the operator to move the sliding frame 5.

[0034] The width of the pulling frame 12 is greater than the width of the lower side of the sliding frame 5, and the pulling frame 12 can move and rotate freely within the moving range of the lower side of the sliding frame 5 without being hindered.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
