The lifting core is hoisted and fixed by the aid of the screw rods and the nuts, and the lifting core is simple in structure, convenient to operate and accurate in positioning.

Drawings

Fig. 1 is a schematic structural diagram of an embodiment of the present invention.

In the figure: 1. the device comprises a hanging core, 1.1 through holes, 1.2 counter bores, 2 screw rods, 3 nuts, 4 sand molds, 4.1 sand mold inner cavities, 5 annular components.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

As shown in figure 1 of the drawings, in which,

the utility model provides a frock is fixed to suspension core, includes screw rod 2 and nut 3, and suspension core 1 hoists in sand mould inner chamber 4.1 through screw rod 2 and

nut

3, and 2 one ends of screw rod can be dismantled with nut 3 and be connected, and 2 other ends of screw rod pass suspension core 1 and with 4 fixed connection of sand mould. Specifically, the suspension core 1 is provided with a through hole 1.1, one end of the suspension core 1 is provided with a counter bore 1.2 communicated with the through hole 1.1, preferably, the counter bore 1.2 is coaxially arranged with the through hole 1.1, and the minimum inner diameter of the counter bore 1.2 is the same as the inner diameter of the through hole 1.1. The screw rod 2 penetrates through the through hole 1.1, the nut 3 is located in the counter bore 1.2, and the nut 3 is in threaded connection with the screw rod 2. A gap is arranged between the screw rod 2 and the through hole 1.1 of the hanging core 1. It should be noted that in one embodiment of the present application, the nut 3 is tightly fitted with the counterbore 1.2 in order to ensure the positioning stability of the suspension core 1.

It should be noted that, this embodiment is hung in sand mould inner chamber 4.1 through hanging core 1 through screw rod 2 and nut 3, convenient and fast, easy operation. The screw rod 2 is matched with the nut 3 in a screwing mode, so that the position of the hanging core 1 in the inner cavity 4.1 of the sand core can be adjusted along the axial direction.

It should be noted that the gap between the screw 2 and the through hole 1.1 in this embodiment is beneficial to the air exhaust during the casting process.

In the present embodiment, the end of the screw 2 remote from the nut 3 is embedded in the sand mold 4, and in order to improve the stability of the screw 2, an annular member 5 is fixedly provided at the end of the screw 2 embedded in the sand mold 4, and the annular member 5 is embedded in the sand mold 4. The annular member 5 in the present embodiment is a circular ring having an outer diameter larger than the diameter of the screw 2.

Compared with the prior art, the embodiment has the beneficial effects that:

the fixed frock of hanging core that this embodiment provided, it leads to screw rod 2 and nut 3 to realize that the hoist and mount of hanging core 1 is fixed, its simple structure, the operation of being convenient for, the location is accurate.

In the description of the present invention, it is to be understood that the terms "coaxial", "bottom", "one end", "top", "middle", "other end", "upper", "one side", "top", "inner", "front", "center", "both ends", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.
