DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, the utility model provides a technical solution: an adjustable positioning device for metal casting, comprising a lower mold 1, an upper mold 2 is arranged on the top of the lower mold 1, air holes 201 are arranged at the four corners of the top of the upper mold 2, a pouring hole 202 is arranged at the central position of the top of the upper mold 2, and the pouring hole 202 corresponds to the pouring funnel 19. Because the pouring hole 202 is arranged, due to the different shapes of metal parts, the position of the pouring hole 202 on the top of the upper mold 2 needs to be adjusted according to the shape of the metal parts, so that the molten metal liquid can be injected between the lower mold 1 and the upper mold 2 through the pouring hole 202;

[0023] Connecting sockets 203 are provided at both ends of the upper mold 2, and the connecting sockets 203 correspond to the clamping column 10. Because the connecting sockets 203 are provided, after the clamping column 10 is inserted into the corresponding connecting sockets 203, the mounting frame 11 is clamped and fixed on the top of the upper mold 2.

[0024] Connecting plates 3 are fixedly installed on the top of both sides of the lower mold 1 and the bottom of both sides of the upper mold 2, and three groups of connecting bolts 4 are equidistantly connected between the connecting plates 3 on both sides of the lower mold 1 and the upper mold 2. By providing the connecting plates 3 and the connecting bolts 4, after the lower mold 1 and the upper mold 2 are correspondingly fitted, the connecting bolts 4 are tightened to ensure that the lower mold 1 and the upper mold 2 are tightly attached and will not separate.

[0025] The upper mold 2 is symmetrically provided with mounting plates 5 on both sides, mounting columns 6 are fixedly installed at both ends of one side of the mounting plate 5, and connecting plates 7 are fixedly installed at one end of the two groups of mounting columns 6 away from the mounting plate 5, and clamping plates 8 are slidably installed on the surfaces of the two groups of mounting columns 6, and clamping springs 9 are provided on the surfaces of the mounting columns 6 located between the connecting plate 7 and the clamping plate 8. Because the clamping springs 9 are provided, the clamping plate 8 is pressed against one side of the mounting plate 5 under the rebound action of the clamping springs 9, so that the clamping column 10 can pass through the mounting plate 5 and be clamped into the corresponding connecting jack 203, so as to facilitate the clamping and fixing of the mounting plate 5;

[0026] The clamping plate 8 is fixedly installed with a clamping column 10 at both ends of the side close to the mounting plate 5, and the clamping column 10 passes through the mounting plate 5. A mounting frame 11 is fixedly installed on the top of the mounting plate 5. A rectangular groove 12 is provided inside the mounting frame 11, and a slide bar 13 is fixedly installed on the inner wall of the rectangular groove 12. A moving block 14 is slidably installed on the surface of the slide bar 13. A slide groove 15 is provided inside the moving block 14, and an arc-shaped clamping block 16 is slidably installed inside the slide groove 15. Two sets of arc-shaped clamping blocks 16 are symmetrically rotated and installed on one side of the arc-shaped clamping block 16. The adjusting knob 17 passes through the moving block 14. The moving block 14 and the arc-shaped clamping block 16 are provided to push the moving block 14 to move on the surface of the slide bar 13. After the casting funnel 19 is controlled to move to a suitable position on the top of the upper mold 2, the adjusting knob 17 is tightened to clamp the arc-shaped clamping block 16 on the surface of the slide bar 13, thereby clamping and fixing the position of the moving block 14 on the surface of the slide bar 13 to ensure that the casting funnel 19 will not move at will on the top of the upper mold 2.

[0027] Two sets of slide bars 18 are fixedly installed between the two ends of the two sets of moving blocks 14, and a pouring funnel 19 is slidably installed between the two sets of slide bars 18. Clamping blocks 1901 are symmetrically fixedly installed on both sides of the surface of the pouring funnel 19, and clamping blocks 1902 are provided on one side of the clamping block 1901, and the clamping blocks 1901 and 1902 are symmetrically clamped on the surface of the slide bars 18. Fixed plates 1903 are symmetrically fixedly installed on both sides of the surfaces of clamping block 1901 and clamping block 2 1902, and fixing bolts 1904 are connected between the fixing plates 1903 opposite to each other on the same side of clamping block 1901 and clamping block 2 1902. Due to the provision of clamping block 1901 and clamping block 2 1902, the pouring funnel 19 is pushed to slide on the surfaces of the two sets of slide bars 2 18 until the pouring funnel 19 is moved to the top of the pouring hole 202, and the fixing bolts 1904 are tightened to fix the pouring funnel 19 between the two sets of slide bars 2 18 to ensure that the pouring funnel 19 will not move and be misaligned with the pouring hole 202 when controlling the metal juice to flow through the pouring funnel 19 to the pouring hole 202.

[0028] The working principle of the utility model is:

[0029] Cover the upper mold 2 on the top of the lower mold 1 accordingly, tighten the connecting bolts 4 to make the lower mold 1 and the upper mold 2 fit tightly, push the clamping plate 8 to both sides to retract the clamping column 10 into the inside of the mounting plate 5, clamp the two sets of mounting plates 5 on both sides of the upper mold 2, so that the clamping column 10 corresponds to the connecting socket 203, loosen the clamping plate 8, and push the clamping plate 8 toward the mounting plate 5 under the elastic action of the clamping spring 9, so that the clamping column 10 passes through the mounting plate 5 and is clamped into the corresponding connecting socket 203, loosen the adjusting knob 17 and the fixing bolt 1904, control the moving block 14 and the pouring funnel 19 to slide on the surfaces of the sliding bar 13 and the sliding bar 2 18 respectively, until the pouring funnel 19 corresponds to the pouring hole 202, tighten the adjusting knob 17 and the fixing bolt 1904, fix the pouring funnel 19 on the top of the pouring hole 202, so that the metal juice can flow through the pouring funnel 19 to the pouring hole 202 and be injected into the lower mold 1 and the upper mold 2.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0031] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
