After the pressing plate contacts the sand mold, the driving device slides down along the guide rod, and the guide rod passes through The reset part is compressed, and the pressure is applied to the pressing plate. During this process, the force of the pressing plate on the sand mold gradually increases, and finally the pressing plate compacts the sand mold in the sand mold. In the utility model, when the pressure plate and the sand mold are initially in contact, the pressure effect is small, and the pressure of the pressure plate is gradually increased when the driving device slides along the guide rod, and there is a buffering process, which can evenly press the sand mold. Solid, good molding quality.

These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and accompanying drawings.

【detailed description】

The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present utility model.

With reference to Fig. 1 and Fig. 2, a kind of sand mold compaction mechanism shown, comprises frame 1, and frame 1 is provided with base 3, pressing plate 4 and driving device 2 that drives pressing plate 4 to lift, and pressing plate 4 is positioned at Directly above the base 3, a sand mold is placed on the base 3, and the driving device 2 drives the pressing plate 4 to move relative to the base 3 to compact the sand mold in the sand mold.

And, be provided with guide rod 5 on the upper surface of platen 4, be provided with the mounting hole 24 that connects guide rod 5 on the driving device 2, the part that guide rod 5 passes through mounting hole 24 is provided with limit block 51, driving device 2 and A reset member 6 is arranged between the pressing plates 4 . The platen 4 is suspended and installed on the driving device 2 through the guide rod 5, and the driving device 2 descends to drive the platen 4 down. After the pressure plate 4 contacts the sand mold, the driving device 2 slides down along the guide rod 5, and the guide rod 5 is compressed The reset member 6 exerts pressure on the pressing plate 4, and during this process, the force exerted by the pressing plate 4 on the sand mold gradually increases, and finally, the pressing plate 4 compacts the sand mold in the sand mold.

The driving device 2 adopted includes a driving cylinder 21 and an upper pressing plate 23 , the bottom of the driving cylinder 21 extends a piston rod 22 connected to the upper pressing plate 23 , and the upper pressing plate 23 is provided with a mounting hole 24 . The driving cylinder 21 drives the piston rod 22 to expand and contract, and the piston rod 22 drives the upper pressing plate 23 to lift, and the upper pressing plate 23 drives the pressing plate 4 to move through the guide rod 5 . The upper platen 23 acts on the pressing plate 4 with an active force, which can make the active force of the pressing plate 4 more uniform, and the effect of compaction is better.

In the utility model, four guide rods 5 are rectangularly distributed on the four corners of the compression plate 4, and the distance between the axis of each guide rod 5 and the axis of the piston rod 22 is equal, so that the compression plate 4 is horizontally arranged.
