Problems solved by technology

[0002] When using a cold box core shooter, during the operation of moving the upper shooting head and blowing frame, due to the very harsh conditions in the foundry, the sand used for core making will be scattered between the moving guide rails and rolling wheels, resulting in The phenomenon that the upper part is stuck and unable to move, which leads to the accident that needs to be shut down to clean the track, which seriously affects the production efficiency

Embodiment Construction

[0020] Such as figure 1 and figure 2 The core-shooting guide rail and rollers shown are fixed by the V-shaped wheel fixed support, and the V-shaped roller realizes positioning. The lower end of the V-shaped roller is placed with a guide rail 22, and the guide rail surface 221 at the upper end of the guide rail 22 is in an inverted V shape at 90 degrees. In this way, the scattered core sand cannot enter the contact gap between the guide rail and the roller, but falls along the slope of the inverted V-shaped guide rail surface.

[0021] The guide rail can be obtained only by rotating the original ordinary plane guide rail by 45°, and at the same time, it is necessary to change the original flat wheel type rolling wheel into a V-shaped wheel. With a slope of 45°, the sand will be scattered to the bottom more easily, which will greatly reduce the problem of the upper part being stuck when moving.

[0022] Such as image 3 Another section of the guide rail shown shows that the ...

Abstract

The invention provides a core shooter guide rail and a core shooter roller. The upper end of the section of the guide rail is provided with a high middle part and two low sides and has an axisymmetric shape such as inverted V shape, circular arc shape, trapezoidal shape and the like. In the core shooter guide rail, the upper part of the guide rail is provided with a slope with inclination, so core forming sand falling on the guide rail naturally slides down to the two ends along a slope-shaped guide rail surface with the high middle part and the two low sides and gets away from the guide rail surface; thus the sand is prevented from entering a contact gap between the guide rail and the roller so as to avoid the phenomenon that the guide rail and the roller are blocked and cannot move. Accordingly, the invention also provides a roller structure which is matched with the appearance of the section of the guide rail.

Description

technical field [0001] The invention relates to a guide rail of a core shooting machine and its matching rollers. Background technique [0002] When using a cold box core shooter, during the operation of moving the upper shooting head and blowing frame, due to the very harsh conditions in the foundry, the sand used for core making will be scattered between the moving guide rails and rolling wheels, resulting in The phenomenon that the upper part is stuck and unable to move, which leads to the accident that needs to be shut down to clean the track, which seriously affects the production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a guide rail structure for a core shooter, which can effectively prevent the sand used for core making from falling between the guide rail and the rolling wheels, ensuring continuous production; [0004] Another technical problem to be solved by the present invention is t...
