Abstract

The utility model discloses a green core mold of a T-shaped junction box, belonging to metal casting modeling, in particular to a modeling mold of a mold core of a hollow casting. The green core mold of the T-shaped junction box comprises an upper core box and a lower core box, and is characterized in that a detachable core box cavity is arranged in the lower core box, and the core box cavity takes a cylindrical end provided with convex ribs and perpendicular to a long shaft and a symmetry plane parallel to the long shaft as an interface to divide the core box cavity into a first half part of the core box cavity and a second half part of the core box cavity. The green core mold of the T-shaped junction box adopts the lower core box provided with the core box cavity which is divided into two parts, the problem of no easy demolding in the modeling is solved, the green core of the T-shaped junction box can be manufactured by adopting the common molding sand, the working efficiency is improved, the cost is lowered compared with the resin sand for core making, and the design method of the mold can be used as reference for the casting with similar shape.

Description

T type terminal box green sand core mould

Technical field

The utility model belongs to the moulding mould of the core of metal casting moulding, particularly hollow casting.

Background technology

T type terminal box is a kind of thin-section casting, there is the cylinder termination that has fin at the core main body major axis two ends of its similar cuboid, there is the cylinder termination that have fin vertical with major axis at the middle part of core main body, be not easy the demoulding according to the conventional method core, maybe need the phenolic sand molding that uses cost higher.

The utility model content

In order to overcome the deficiency of the unsuitable demoulding of existing mould, the purpose of this utility model provides a kind of T type terminal box green sand core mould, and this T type terminal box green sand core mould not only goes for the moulding of common sand green sand core.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of T type terminal box green sand core mould, comprise core box, following core box, it is characterized in that: in the described down core box dismountable core box chamber is housed, this core box chamber is that interface is divided into core box chamber first half and the core box chamber is latter half of with the plane of symmetry parallel with major axis with the vertical cylinder termination that has fin of major axis of core.

Core main body major axis two ends with similar cuboid when using the utility model have the plane of symmetry of the cylinder termination that has fin to make upward core box, following core box as benchmark, core box is identical with common core box on it, it is equipped with the core box chamber in core box down, the core box chamber is divided into core box chamber first half and the core box chamber is latter half of, and it is benchmark that there is the plane of symmetry of the cylinder termination that have fin vertical with major axis in its line of demarcation with the middle part of core main body.

The disclosed T type of the utility model terminal box green sand core mould, adopt down and be provided with core box divided into two parts chamber in the core box, solved unsuitable release problems in the moulding, realized use common sand making T type terminal box green sand core, improved operating efficiency, use resin sand to make core and reduce cost, this Mould design method can be used as the reference of analogous shape foundry goods.

Description of drawings

Accompanying drawing 1 is the structural representation of following core box in the utility model,

Fig. 2 is the structural representation of following core box in the utility model,

Fig. 3 is a T type terminal box green sand core schematic perspective view,

Fig. 4 is that the A-A in core box chamber among Fig. 1 is to cutaway view.

Among the figure, 1. descend core box, 2. core box chamber first half, 3. the core box chamber is latter half of, 4. goes up core box, the 5. core main body of similar cuboid, 6. the major axis two ends have the cylinder termination of fin, 7. fin, 8. vertical with the major axis cylinder termination that has fin.

The specific embodiment

The specific embodiment of the present utility model is, as shown in the figure:

Embodiment 1, a kind of T type terminal box green sand core mould, comprise core box 4, following core box 1, core main body 5 major axis two ends with similar cuboid have the plane of symmetry of the cylinder termination 6 that has fin to be the last core box of interface making, to descend core box, dismountable core box chamber is housed in the following core box, and this core box chamber is that interface is divided into core box chamber first half 2 and core box chamber latter half of 3 with the plane of symmetry parallel with major axis with the vertical cylinder termination 8 that has fin 7 of major axis of core.

Claims

1. T type terminal box green sand core mould, comprise core box, following core box, it is characterized in that: in the described down core box dismountable core box chamber is housed, this core box chamber is that interface is divided into core box chamber first half and the core box chamber is latter half of with the plane of symmetry parallel with major axis with the vertical cylinder termination that has fin of major axis of core.
