Description

Technical Field

[0001] The utility model relates to the field of casting equipment, in particular to a valve body production casting equipment. Background Art

[0002] The valve body is an important component of the valve, usually made of metal or alloy materials. Its main function is to provide support and sealing for the internal structure of the valve. The valve body is usually produced by casting. The equipment required for casting includes a crucible and a mold. The metal block as the raw material is placed on the crucible and then the crucible is heated until the metal in the crucible melts into liquid. The crucible is then transferred to the top of the mold, and the metal liquid in the crucible is then poured into the injection hole reserved on the surface of the mold. After the metal liquid cools and takes shape, it is demolded to complete the casting.

[0003] In the prior art, when transferring the crucible, crucible tongs are usually used to clamp the crucible. When heating the crucible, the crucible tongs are not set on the crucible and heated together with the crucible. Therefore, using the crucible tongs to transfer the crucible after the crucible is heated can prevent the temperature on the crucible tongs from being too high, which may cause burns to the hands of the workers holding the crucible tongs.

[0004] However, existing crucible tongs usually clamp the crucible by means of two metal rods connected by rotation at the middle part. When clamping, the worker needs to hold the end of the crucible tongs away from the crucible to provide clamping force for the end of the crucible clamped by the crucible. A slight slackness may lead to insufficient clamping force and cause the crucible to fall from the crucible tongs. Once the crucible falls on the ground, the metal liquid inside it splashes, which is likely to cause injuries to surrounding personnel. Utility Model Content

All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figure 1-Figure 3 The utility model provides a technical solution: a valve body production casting equipment, comprising: a crucible 1, a connecting seat 2 is fixed on the surface of the crucible 1, a plug-in groove 3 is provided on the surface of the connecting seat 2, a plug-in rod 4 is movably plugged in the plug-in groove 3, one end of a limiting block 8 is movably plugged in the surface of the plug-in rod 4, the other end of the limiting block 8 is movably plugged in the limiting groove 9, the limiting groove 9 is provided on the inner wall of the plug-in groove 3, a connecting rod 10 is fixed on one end of the plug-in rod 4 extending out of the plug-in groove 3, and a holding rod 14 is fixed on the other end of the connecting rod 10.

[0021] In actual use, when the crucible 1 and the metal raw material in the crucible 1 are heated, the plug-in rod 4 and the connecting seat 2 are in a separated state. After the metal raw material in the crucible 1 is heated and melted into a liquid state, the limit block 8 is first completely retracted into the cavity of the plug-in rod 4, and then the plug-in rod 4 fixed by one end of the connecting rod 10 is inserted into the plug-in slot 3. After the limit block 8 is aligned with the limit slot 9, one end of the limit block 8 is automatically inserted into the limit slot 9, and the other end of the limit block 8 still stays in the cavity of the plug-in rod 4, thereby limiting the plug-in rod 4 in the plug-in slot 3, and then the holding rod 14 fixed at the other end of the connecting rod 10 can be held to transfer the crucible 1. When the valve body production casting equipment transfers the crucible 1, the connecting rod 10 The limiting force comes from the squeezing force of the inner wall of the limiting groove 9 on the limiting block 8 and the squeezing force of the inner wall of the plug-in groove 3 on the plug-in rod 4. Therefore, there is no need to rely on the worker's grip to provide clamping force, which can effectively prevent the crucible 1 from falling during the transfer process; at the same time, the connecting rod 10 and the plug-in rod 4 are both made of metal materials, which can prevent melting by the high temperature transmitted from the crucible 1. The holding rod 14 is made of plastic material. When the high temperature of the crucible 1 is transmitted to the end of the connecting rod 10 where the holding rod 14 is fixed, it will no longer cause damage to the holding rod 14, but it can still cause burns to the workers. Therefore, the holding rod 14 is made of plastic material, which can isolate the temperature transmitted from the connecting rod 10 and prevent the workers from getting burned when holding the holding rod 14.

[0022] Embodiment 2

[0023] On the basis of the first embodiment, in order to realize the control of the movement of the limit block 8, a cavity is provided inside the plug-in rod 4, and an inclined surface is provided at one end of the limit block 8 extending into the cavity of the plug-in rod 4, and a fiber spring 5 is fixed to one end of the limit block 8 extending into the cavity of the plug-in rod 4, and the other end of the fiber spring 5 is fixed to the inner wall of the cavity of the plug-in rod 4, and a push rod mounting groove 11 is provided on the surface of the connecting rod 10, and one end of the push rod 7 is movably inserted in the push rod mounting groove 11, and the other end of the push rod 7 is movably inserted in the cavity of the plug-in rod 4, and a protective plate is fixed to the inner wall of the cavity of the plug-in rod 4 6. The protection plate 6 is arranged between the fiber spring 5 and the push rod 7. One end of the push rod 7 extending into the push rod installation groove 11 is fixed with a steel wire rope 12 and a push spring 13. The other end of the push spring 13 is fixed on the inner wall of the push rod installation groove 11. The other end of the push spring 13 is movably inserted in the rope hole 15. The rope hole 15 is opened on the surface of the holding rod 14. The end of the rope hole 15 away from the push rod 7 extends out from the rope hole 15 and is fixed with a pull ring 16. The push rod installation groove 11 is a circular groove body, the rope hole 15 is a circular hole structure, and the diameter of the push rod installation groove 11 is larger than the rope hole 15.

[0024] When the limit block 8 needs to be completely retracted into the cavity of the plug-in rod 4, the worker only needs to hold the holding rod 14 with one hand and pull the pull ring 16 away from the holding rod 14 with the other hand. The pull ring 16 drives the push rod 7 to move in the same direction through the push spring 13 in the rope hole 15, so that the push rod 7 is completely retracted into the push rod installation groove 11. The fiber spring 5 in the stretched state generates a pulling force on the limit block 8 under its own elastic action, and the limit block 8 is completely pulled into the cavity of the plug-in rod 4; as the push rod 7 is The steel wire rope 12 is pulled into the push rod installation groove 11, and the push spring 13 is compressed. When the limit block 8 needs to be inserted into the limit groove 9, just loosen the pull ring 16. The push spring 13 pushes one end of the push rod 7 back into the cavity of the plug-in rod 4 under its own elastic action. One end of the push rod 7 slides over the inclined surface of the limit block 8, generating a thrust on the limit block 8. This thrust can be decomposed into two components, one of which pushes the limit block 8 out of the cavity of the plug-in rod 4, thereby inserting the limit block 8 into the limit groove 9.

[0025] Embodiment 3

[0026] On the basis of the second embodiment, in order to prevent the push rod 7 from damaging the fiber spring 5 , a protection plate 6 is fixed on the inner wall of the cavity of the plug rod 4 , and the protection plate 6 is arranged between the fiber spring 5 and the push rod 7 .

[0027] When the push rod 7 extends into the cavity of the plug-in rod 4, the push rod 7 finally comes into contact with the surface of the protection plate 6 and cannot move further, so that the protection plate 6 protects the fiber spring 5 and prevents the push rod 7 from squeezing the fiber spring 5 from the side and damaging the fiber spring 5.

[0028] In actual use, when the crucible 1 and the metal raw material in the crucible 1 are heated, the plug-in rod 4 and the connecting seat 2 are in a separated state. After the metal raw material in the crucible 1 is heated and melted into a liquid state, the limit block 8 is first completely retracted into the cavity of the plug-in rod 4, and then the plug-in rod 4 fixed by one end of the connecting rod 10 is inserted into the plug-in slot 3. After the limit block 8 is aligned with the limit slot 9, one end of the limit block 8 is automatically inserted into the limit slot 9, and the other end of the limit block 8 still stays in the cavity of the plug-in rod 4, thereby limiting the plug-in rod 4 in the plug-in slot 3, and then the holding rod 14 fixed at the other end of the connecting rod 10 can be held to transfer the crucible 1. This valve body production casting equipment is suitable for the crucible 1. During the transfer, the limiting force of the connecting rod 10 on the crucible 1 comes from the squeezing force of the inner wall of the limiting groove 9 on the limiting block 8 and the squeezing force of the inner wall of the plug-in groove 3 on the plug-in rod 4. Therefore, it is no longer necessary to rely on the worker's grip to provide a clamping force, which can effectively prevent the crucible 1 from falling during the transfer process; at the same time, the connecting rod 10 and the plug-in rod 4 are both made of metal materials, which can prevent melting by the high temperature transmitted from the crucible 1. The holding rod 14 is made of plastic material. When the high temperature of the crucible 1 is transmitted to the end of the connecting rod 10 where the holding rod 14 is fixed, it will no longer cause damage to the holding rod 14, but it can still cause burns to the workers. Therefore, the holding rod 14 is made of plastic material, which can effectively prevent the crucible 1 from falling during the transfer. The temperature transmitted from the rod 10 is isolated to prevent the worker's hand from being scalded when holding the holding rod 14; when the limit block 8 needs to be completely retracted into the cavity of the plug-in rod 4, the worker only needs to hold the holding rod 14 with one hand and pull the pull ring 16 away from the holding rod 14 with the other hand. The pull ring 16 drives the push rod 7 to move in the same direction through the push spring 13 in the rope hole 15, so that the push rod 7 is completely retracted into the push rod installation groove 11. The fiber spring 5 in the stretched state generates a pulling force on the limit block 8 under the action of its own elasticity, and the limit block 8 is completely pulled into the cavity of the plug-in rod 4; as the push rod 7 is pulled into the push rod installation groove 11 by the wire rope 12, the push spring 13 is compressed. When the positioning block 8 is inserted into the limiting groove 9, it is only necessary to loosen the pull ring 16, and the pushing spring 13 will push one end of the pushing rod 7 back into the cavity of the plug-in rod 4 under its own elastic action, and one end of the pushing rod 7 will slide over the inclined surface of the limiting block 8, generating a thrust on the limiting block 8. This thrust can be decomposed into two components, one of which pushes the limiting block 8 out of the cavity of the plug-in rod 4, so that the limiting block 8 is inserted into the limiting groove 9; when the pushing rod 7 extends into the cavity of the plug-in rod 4, the pushing rod 7 finally rests on the surface of the protective plate 6 and cannot continue to move, so that the protective plate 6 protects the fiber spring 5 and prevents the pushing rod 7 from squeezing the fiber spring 5 from the side and damaging the fiber spring 5.
