Abstract

The utility model provides a sand core structure. The sand core structure comprises a sand core body, a long and flat portion is arranged on the sand core body, supporting steel tubes for supporting are arranged in the sand core body, a reinforced steel plate is arranged in the sand core body, and the reinforced steel plate and the supporting steel tubes jointly support the sand core body. In view of the specific structure of a sand core, the sand core can not be fully supported on the long and flat portion just by the steel tubes, and the sand core can deform; if the steel tubes are used alone, the long and flat structure can not contain more steel tubes because the diameter of the steel tubes is large. Therefore, the combined structure of the steel tubes and the steel plate is used in the long and flat structure, the structural strength of the sand core can be guaranteed, and deformation of the sand core structure due to structural reasons can be avoided.

Description

Sand core structure

Technical field

The utility model relates to casting field, relates to specifically a kind of sand core structure.

Background technology

Core belongs to parts more common in casting field, the structure of core and size are also all not quite similar according to actual needs, in general, to the core with small-sized, only need simply in die for molding, can use, and for some comparatively large-scale cores, steel pipe just need to be set in core the inside, core is played a supporting role, avoid the distortion of core, to the installation of core move and the intensity of core all highly beneficial, concrete structure designs reinforcement according to actual needs, different cores can need the reinforcement of different structure, such as: it is larger that applicant runs into volume in practice process, and while thering is the core of first draft structure, conventional steel-tube construction is set can not well supports, in first draft structure, still there will be distortion, the concrete structure of limited and core, can not strengthen supporting role by increasing steel pipe, therefore need to design the new sand core structure with better non-deformability.

Utility model content

Technical problem to be solved in the utility model is, provides a kind of anti-deformation better, is easy to the sand core structure of realizing.

For solving the problems of the technologies described above, the sand core structure that the utility model provides, it comprises core body, core body is provided with long flat part, in core body, be provided with as the supporting steel pipe supporting, in core body, be also provided with reinforcement steel plate, strengthen steel plate and supporting steel pipe and jointly core body is played a supporting role.

The two ends of core body are provided with supplemental support steel plate.

Adopt after above structure, the utility model compared with prior art, has the following advantages:

Concrete structure in view of core, at long flat place, just with steel pipe, cannot guarantee enough supports, core will be out of shape, and uses separately steel pipe because the diameter of steel pipe is larger, and long flat structure cannot be held more steel pipe, therefore, the structure of using steel pipe and steel plate to combine at long flat structure place, can guarantee the structural strength of core, avoids core to be out of shape because of reasons in structure.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model sand core structure;

Fig. 2 is the structural representation of the inner reinforcement of the utility model sand core structure.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Shown in Fig. 1, Fig. 2, the utility model sand core structure, it comprises core body 1, the middle part long flat part 1.1 of core body 1, and two ends are respectively the spheroidal structure of class, in core body 1, be provided with as the supporting steel pipe 2 supporting, consider the flat structure of length in core body 1, in core body 1, be also provided with and strengthen steel plate 3, therefore, emphasis of the present utility model is: strengthening steel plate 3 and supporting steel pipe 2 and jointly core body 1 is played a supporting role, is not single supporting steel pipe 2.According to the solid construction of core body 1 two ends spheroidal, at the two ends of core body 1, be provided with supplemental support steel plate 4, the supplemental support steel plate 4 here can arranged crosswise, specifically will be according to the concrete structure of core body 1.
