Detailed Description

The following describes a specific embodiment of the present embodiment with reference to the drawings.

Fig. 1 is a schematic structural diagram of the present invention. Fig. 2 is an enlarged view of a point a in fig. 1. Fig. 3 is a side view of the boom of the present invention. As shown in the combined drawings of figure 1, figure 2 and figure 3, the utility model discloses a stirring paddle casting sand box. The direction of X in the figure does the utility model discloses structure schematic's upper end, the direction of Y in the figure does the utility model discloses structure schematic's right-hand member. The stirring paddle casting sand box comprises a box cover 1, a box bottom 2, a locking device 3 for pressing the box cover 1 and a supporting plate 4 for supporting the box bottom 2. The locking device 3 is arranged on the box bottom 2. The case cover 1 is provided with a positioning hole 11. The box bottom 2 is provided with a positioning pin 21 embedded into the positioning hole 11.

Preferably, the cover 1 is trapezoidal. Preferably, the bottom 2 is trapezoidal. The stirring part of the stirring paddle is conical. The sand box is used for casting the stirring paddle, and because the stirring paddle is special in shape, the sand box adopting the traditional shape can cause serious waste of casting sand. The trapezoidal inclined plane of case lid 1 is the upper surface of case lid 1, and the trapezoidal inclined plane of the bottom of the case 2 is the lower surface of the bottom of the case 2. The box cover 1 and the box bottom 2 are designed to be trapezoidal, so that the amount of casting sand can be reduced when the stirring paddle is cast, and the manufacturing cost is reduced.

The stirring paddle casting sand box also comprises a sand hook 5. The sand hooks 5 are respectively arranged in the box cover 1 and the box bottom 2 in parallel. Preferably, the hooks 5 are J-shaped.

Preferably, the plurality of hooks 5 is provided. The sand hooks 5 are respectively connected in parallel at the upper end of the inner surface of the box cover 1 and the lower end of the inner surface of the box bottom 2. When the sand mold is arranged in the box cover 1, the sand hook 5 improves the strength of the sand mold in the box cover 1. When the sand mold is arranged in the box bottom 2, the sand hook 5 improves the strength of the sand mold in the box bottom 2.

The sand mould needs drawing and overturning in the casting process of the stirring paddle, and the sand hooks 5 are arranged in the box cover 1 and the box bottom 2, so that the local sand mould can be prevented from being broken in the drawing and overturning processes.

The box cover 1 and the box bottom 2 are respectively provided with a supporting rib 7. The supporting ribs 7 are respectively arranged on the upper surface of the case cover 1 and the lower surface of the case bottom 2.

Preferably, the number of the support ribs 7 is plural. Preferably, the support rib 7 is cross-shaped. The supporting ribs 7 are respectively arranged on the upper surface of the box cover 1 and the lower surface of the box bottom 2 in parallel. The supporting ribs 7 respectively play a role in strengthening the structure of the box cover 1 and the box bottom 2. The supporting ribs 7 play a role in strengthening the structure of the sand box. Because the dead weight of the stirring paddle and the sand mould is heavy, the box cover 1 and the box bottom 2 can be prevented from being broken through the support rib 7.

The box cover 1 and the box bottom 2 are respectively provided with a suspender 6 which is convenient for turning over the sand box. A V-shaped groove 61 is opened around the suspension lever 6.

Preferably, the boom 6 is plural. The hanging rods 6 are respectively arranged at two ends of the box cover 1 and two ends of the box bottom 2. The V-shaped groove 61 is opened on the outer surface of the suspension lever 6. When the stirring paddle is used for casting, the sand box needs to be turned over, and the sand box is turned over through the lifting hook.

The hanging ring of the lifting hook is sleeved on the hanging rod 6, and the sand box is lifted by the lifting hook to be turned. The lifting hook can be limited to move through the V-shaped groove 61, the lifting ring is prevented from sliding along the outer surface of the suspender 6, and the sand box is effectively prevented from falling when being turned.

The locking device 3 comprises a bracket 31 arranged on the box bottom 2, a sleeve 32 connected to the bracket 31 in a swinging manner, and a screw 33 connected to the sleeve 32 in a threaded manner. The box cover 1 is provided with a connecting plate 12. The end of the screw 33 remote from the tank bottom 2 presses the connecting plate 12.

Preferably, the connecting plate 12 is a U-shaped plate. The bracket 31 is fixedly connected to one end of the box bottom 2 close to the box cover 1. The screw 33 is screwed in and out along the sleeve 32. When the locking device 3 needs to press the box cover 1, the screw 33 is screwed anticlockwise, the screw 33 is screwed out along the sleeve 32, the screw 33 is placed in the opening of the connecting plate 12, the screw 33 is screwed clockwise, the screw 33 is screwed in along the sleeve 32, and the screw 33 presses the connecting plate 12. The tightness between the box cover 1 and the box bottom 2 can be ensured by the locking device 3.

A positioning hole 11 is opened around the lower surface of the case cover 1. Around the upper surface of the tank bottom 2, positioning pins 21 are provided. When the sand box is closed, the box cover 1 is arranged at the upper end of the box bottom 2, and the positioning pins 21 are embedded into the positioning holes 11. The positioning pins 21 prevent the cover 1 from being displaced when it is mounted.

One end of the positioning pin 21 fitted into the positioning hole 11 is provided with a moving pin 22. The elastic means 23 are pressed outwards against the moving pin 22.

Preferably, the elastic means 23 are springs. The moving pin 22 is movably provided at an upper end of the positioning pin 21. When the positioning pin 21 is inserted into the positioning hole 11, the elastic means 23 pushes the moving pin 22 outward, and the moving pin 22 abuts against the inner surface of the positioning hole 11. The positioning pin 21 can be stably inserted into the positioning hole 11 by moving the pin 22.

The supporting plate 4 is arranged at the lower end of the box bottom 2. The upper end of the supporting plate 4 is connected with the lower end of the box bottom 2. Because the box bottom 2 is trapezoidal, the lower extreme of box bottom 2 is unstable. The supporting plate 4 can provide stable support for the sand box.

In the present embodiment, the elastic device 23 is described as a spring, but the present invention is not limited thereto, and may be another elastic device within a range capable of functioning.

In the present specification, terms such as "trapezoid", "J-shape", "cross" and "U-shape" are used, and these terms are not exactly "trapezoid", "J-shape", "cross" and "U-shape", and may be in a state of "substantially trapezoid", "substantially J-shape", "substantially cross" and "substantially U-shape" within a range in which the functions thereof can be exerted.

In the present specification, the number of the "plural" or the like is used, but the present invention is not limited thereto, and other numbers may be used within a range where the function thereof can be exerted.
