Description
Technical Field
[0001] The utility model relates to the technical field of horizontal parting molding machines, in particular to a core box demoulding mechanism for a horizontal parting molding machine. Background Art
[0002] In the traditional horizontal parting core making process, the demoulding operation of the core box is usually achieved through the core-lifting mechanism set in the lower core box. This structure and method have some inherent limitations and problems in the actual application process. Specifically, since only the lower core box is equipped with a core-lifting mechanism, in the process of forming the sand core after the mold is closed, the upper core box lacks a corresponding demoulding auxiliary device, resulting in a strong adhesion force between the upper core box and the solidified sand shell during the mold opening stage, making it easy for the sand shell to follow the movement of the upper core box when the upper core box is separated, resulting in demoulding difficulties. The sand shell is easily deformed, cracked, or even damaged as a whole by artificial sand shell.
[0003] This defect in the prior art not only affects the quality stability and production efficiency of the sand shell, but also increases the scrap rate and maintenance cost of the sand shell, limiting the reliability and economic benefits of the horizontal parting core making machine in a continuous mass production environment. Therefore, we propose a core box demoulding mechanism for a horizontal parting core making machine. Utility Model Content

[0026] In this embodiment, the upper core box moving mechanism 6 includes an upper core box moving plate 61 and a forward and reverse motor 64.

A screw rod 65 is fixedly installed on the output end of the forward and reverse motor 64. The lower end of the screw rod 65 is movably connected to the lower extension plate 10, and the screw rod 65 is threadedly connected to the adjusting block 63. The upper core box main body is fixedly installed in the middle of the lower end of the upper core box moving plate 61. The position of the upper core box body 62 corresponds to the position of the lower core box body 9; the screw rod 65 is driven to rotate by the forward and reverse motor 64, and the adjusting block 63 is moved up by the screw rod 65 and the adjusting block 63 being threadedly connected. With the cooperation of the four columns 4, the upper core box moving plate 61 is moved up smoothly, which improves the stability of the upper core box moving plate 61 during the movement, further ensures the yield rate of the sand shell, reduces the production cost, and has a high demoulding efficiency, thereby improving the reliability and economic benefits of the horizontal parting core making machine in a continuous mass production environment.
[0027] In this embodiment, the upper core box core pushing mechanism 8 includes an electric telescopic rod 81, which is fixedly mounted on the upper end of the top plate 5, and a triangular plate 82 is fixedly mounted on the output end of the electric telescopic rod 81, which is located at the lower end of the top plate 5, and three core pushing rods 83 are fixedly mounted on the lower end of the triangular plate 82, and the three core pushing rods 83 are distributed in a triangular shape; the structure of the lower core box core pushing mechanism 7 is the same as that of the upper core box core pushing mechanism 8, and the lower core box core pushing mechanism 7 and the upper core box core pushing mechanism 8 are symmetrically distributed up and down; the rear ends of the bottom plate 3 and the top plate 5 are fixedly welded with an extension plate 10; the upper core box moving plate 61 and the side of the bottom plate 3 away from the opposite end are each provided with three holes that penetrate the upper core box body respectively 62 and the top core through hole 66 inside the lower core box body 9, the top core through hole 66 corresponds to the position of the top core rod 83 and the size is adapted; by arranging the upper core box top core mechanism 8 above the upper core box moving plate 61, the electric telescopic rod 81 is extended to push the triangular plate 82 to move downward, so that the three top core rods 83 respectively penetrate the three top core through holes 66 at the upper end of the upper core box moving plate 61, and act on the sand shell in the upper core box body 62 through the top core through holes 66, ensuring that the sand shell remains in the lower core box body 9, effectively preventing the sand shell from following the movement of the upper core box body 62 when the upper core box body 62 is separated, facilitating demoulding, thereby avoiding the problem of artificial deformation, rupture or even overall damage of the sand shell.
[0028] It should be noted that the utility model is a core box demoulding mechanism for a horizontal parting molding machine. During use, when the sand shooting action is completed and the curing time is reached, the upper core box core pushing mechanism 8 is started, and the triangular plate 82 is pushed downward by extending the electric telescopic rod 81, so that the three core pushing rods 83 respectively penetrate the three core pushing through holes 66 at the upper end of the upper core box moving plate 61, and act on the sand shell in the upper core box body 62 through the core pushing through holes 66 to ensure that the sand shell remains in the lower core box body 9, and then the forward and reverse motor 64 is started, and the screw rod 65 is driven to rotate by the forward and reverse motor 64, and the adjusting block 63 is moved up by the screw rod 65 and the adjusting block 63 threaded connection.

The stability in the middle is effectively avoided, and the sand shell is easily prevented from following the movement of the upper core box body 62 when the upper core box body 62 is separated, which is convenient for demoulding, thereby avoiding the problem that the sand shell is easily deformed, broken or even damaged as a whole by artificial means. At this time, during the upward movement of the upper core box moving plate 61, the electric telescopic rod 81 is simultaneously contracted to prevent the triangular plate 82 from hindering the upward movement of the upper core box moving plate 61 until the sand shell is completely left in the lower core box body 9. At the same time, the lower core box core pushing mechanism 7 works, and the three core pushing rods 83 on the lower core box core pushing mechanism 7 are used to push the sand shell out of the lower core box body 9, completing the demoulding of the sand shell, ensuring the yield rate of the sand shell, reducing the production cost, and the entire demoulding efficiency is high, which improves the reliability and economic benefits of the horizontal parting core making machine in a continuous mass production environment.
