[0007] Wherein, a first gasket is arranged between the first nut and the elastic member.
[0008] Wherein, the elastic member is a spring.
[0009] Wherein, a second gasket is arranged between the elastic member and the cover plate.
[0010] Wherein, an iron ring is arranged inside the rubber ring.
[0011] Wherein, a third gasket is arranged between the plastic cover and the third nut.
[0012] Wherein, a convex structure is arranged on one side of the clamping head.
[0013] Beneficial effects of the utility model:
[0014] The utility model provides an improved hook. After the hook and the die head are installed, the plastic cover head contacts the die head and is locked under the action of the elastic member. If the die head is immersed in liquid by operating the hook, the rubber ring of the plastic cover head can cover the cover plate, the elastic member, the nut and other parts, so that the parts of the hook are protected when the hook is immersed in liquid, thereby improving the service life of the hook.

DETAILED DESCRIPTION
[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0021] At present, in the process of casting production, the casting mold needs to be made and hung and dried. The casting mold is connected to the hook through the die head and then hung on the drying equipment for drying.
[0022] In the prior art, the end of the hook is connected to the hanging body of the mold through a thread; when connecting, the end of the hook needs to be extended to the hanging body of the die head for connection. After the connection, the hook is locked with the die head through parts such as a cover plate, an elastic part, and a nut, and the die head needs to be immersed in liquid for filling or cleaning. Due to the different heights of different liquids, the above parts are easily soaked or splashed by the liquid, which is easy to corrode the above parts over time, affecting the connection performance of the hook.
[0023] In order to solve the above problems, this embodiment discloses an improved hook, the structure of which is as follows: Figure 1 As shown, the hook includes a hook body 100 and a screw rod 101 connected to one end of the hook body 100. From one end of the screw rod 101 close to the hook body 100 to the other end, a first nut 102, an elastic member 104, a cover plate 105, a plastic cover head 106, a second nut 103, a third nut 107 and a clamp head 108 are sequentially arranged. Preferably, the elastic member 104 is a spring, and a convex structure 114 is arranged on one side of the clamp head 108 to facilitate its connection with the die head. The first nut 102, the second nut 103, the third nut 107 and the clamp 108 are respectively screwed to the screw rod 101. Generally, a rubber plug 116 is provided at the clamp 108 for protection. The elastic member 104, the cover plate 105 and the plastic cover 106 are respectively provided on the screw rod 101. The plastic cover 106 includes a rubber pad 109 and a rubber ring 110 which protrudes toward the direction of the hook body 100 and is arranged around the rubber pad 109.
[0024] Furthermore, a first gasket 111 is provided between the first nut 102 and the elastic member 104, a second gasket 112 is provided between the elastic member 104 and the cover plate 105, and a third gasket 113 is provided between the plastic cover head 106 and the third nut 107, which can reduce friction between parts and effectively improve the service life of the hook.
[0025] Furthermore, an iron ring 115 is disposed inside the rubber ring 110 , and the iron ring 115 can reduce the collapse of the rubber ring 110 when it is tilted, thereby preventing the rubber ring 110 from losing its effectiveness.
[0026] In summary, an improved hook in this embodiment, after the hook and the die are installed, the plastic cover 106 contacts the die and is locked under the action of the elastic member 104; if the hook is operated to immerse the die in liquid, the rubber ring 110 of the plastic cover 106 can cover the cover plate 105, the elastic member 104, the nut and other parts, so as to protect the parts of the hook when the hook is immersed in liquid and improve the service life of the hook.
[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
