When pushing the adjustment screw to rotate, no special tools such as wrenches are needed, and the purpose of saving effort can be achieved at the same time. However, in most existing casting furnaces for hardware casting, the heat preservation layer and the whole furnace body are of an integrated structure. Therefore, when the heat preservation layer is damaged subsequently, it will affect the normal use of the whole casting furnace for hardware casting, that is, the replacement of the whole forging furnace needs to be realized, which is not only time-consuming and laborious, but also increases the consumption of resources, and the practicability is not good. Summary of the Utility Model

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a casting furnace for hardware casting, which can solve the technical problems that in the existing casting furnace for hardware casting, the power arm length of the rotating adjustment screw is extended through the flipped part after flipping. When pushing the adjustment screw to rotate, no special tools such as wrenches are needed, and the purpose of saving effort can be achieved at the same time. However, in most existing casting furnaces for hardware casting, the heat preservation layer and the whole furnace body are of an integrated structure. Therefore, when the heat preservation layer is damaged subsequently, it will affect the normal use of the whole casting furnace for hardware casting, that is, the replacement of the whole forging furnace needs to be realized, which is not only time-consuming and laborious, but also increases the consumption of resources, and the practicability is not good.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A casting furnace for hardware casting, including a base, a furnace body is arranged in the middle of the top of the base, a melting cavity is opened inside the furnace body, a clamping structure is opened on the periphery of the furnace body, a heat preservation layer is distributed above the furnace body, a strip-shaped groove is opened on the inner side wall of the heat preservation layer, a limiting convex block is arranged on one side of the top end of the heat preservation layer, a clamping block is arranged at one end of the top of the heat preservation layer, a first spring is fixedly connected to the inner cavity of the limiting convex block, and the other end of the first spring is fixedly connected to a locking rod, and an auxiliary sliding plate is sleeved on the outer side of one end of the locking rod.

[0006] As a preferred technical solution of the present utility model, the engaging structure includes a fitting groove, a rib, a groove, a lock hole and a card slot. The fitting groove is opened on the outer periphery of the top end of the furnace body, and a rib is provided on the inner side of the fitting groove. One side of the top end of the fitting groove communicates with a groove, and the other side of the groove communicates with a lock hole. A card slot is opened on the inner side wall of the outer periphery of the top end of the furnace body.

[0007] As a preferred technical solution of the present utility model, a second spring is fixedly connected to the bottom of the inner cavity of the furnace body, and a buffer pad is fixedly connected to the other end of the second spring.

[0008] As a preferred technical solution of the present utility model, a side frame is fixedly installed on one side of the top end of the base, and a motor is provided in the middle of the top end of the side frame. The output end of the motor is connected to a threaded rod.

[0009] As a preferred technical solution of the present utility model, a pressing cover is distributed above the heat insulation layer, and a threaded sleeve is fixedly installed on the side wall of the pressing cover.

[0010] As a preferred technical solution of the present utility model, the threaded rod is threadedly connected to the threaded sleeve through a threaded groove, and the threaded sleeves are symmetrically distributed along the vertical center line of the pressing cover.

[0011] Compared with the prior art, the beneficial effects that the present utility model can achieve are:

[0012] 1. By combining the provided clamping block, limiting convex block, first spring and locking rod, it is convenient to quickly disassemble and replace the heat insulation layer subsequently. Compared with the existing integrated forging furnace, this structure has higher practicability and flexibility, can quickly replace the heat insulation layer, and no longer requires replacing the entire forging furnace when the heat insulation layer is damaged. The overall practicability is higher. When the heat insulation layer drives the clamping block and the limiting convex block to be clamped and connected with the furnace body, the reverse force generated by the deformation of the first spring will horizontally push the locking rod, and then input one end of the locking rod into the inner side of the furnace body to achieve the quick connection between the heat insulation layer and the furnace body and facilitate subsequent replacement;

[0013] 2. By combining the provided second spring and buffer pad, it is convenient to buffer and protect the heat insulation layer when it is clamped inside the furnace body subsequently, so as to prevent the heat insulation layer from being damaged due to excessive impact force when it is clamped with the furnace body, affecting the subsequent normal heat insulation effect. When the buffer pad receives a longitudinal force, it will squeeze the second spring and cause the second spring to deform and generate a reverse force. Then, the reverse forces generated by the deformation of multiple second springs can achieve the purpose of buffer protection. Description of the Drawings

A clamping groove 8 is opened on the inner side wall of the outer periphery of the top end of the furnace body 2. The adaptation groove 4, the rib 5, the groove 6, the lock hole 7 and the clamping groove 8 form a clamping structure, and the clamping structure is arranged on the inner side of the outer periphery of the furnace body 2.
