Description

A kind of floor structure for the casting of spacecraft deck store

Technical field

The utility model belongs to casting technology field, and in particular to a kind of floor structure for the casting of spacecraft deck store.

Background technique

Currently, in the cabin casting of spacecraft, since its deck store part generally requires to install most components, knot Structure is also that complexity is all made of setting gap running channel and using pressure in general casting process the most in all cabin base parts The method of difference casting is cast, but since the complexity of deck store structure is big, is connected with gap running channel binding in conventional bottom plate Under structure, it frequently can lead to non-uniform temperature in cooling procedure and cause the surface defects such as the shrinkage cavity even generation of crackle, therefore, it is necessary to A kind of floor structure dedicated for carrying out deck store casting is provided, flow velocity adjusting is carried out to casting liquid and makes it in cooling procedure Heat distribute and more uniformly prevent the surface defect of deck store casting from occurring.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of floor structure for the casting of spacecraft deck store.

The utility model is achieved by the following technical programs.

A kind of floor structure for the casting of spacecraft deck store provided by the utility model, including bottom plate, center casting gate And lateral sprue, wherein bottom plate be it is discoid, center casting gate is set at the center of bottom plate；Lateral sprue is more It is a, it is distributed on bottom plate, is connected to center casting gate and extends to the outside of bottom plate；It is additionally provided on the outside of bottom plate multiple pointed prominent Portion out, the multiple pointed protruding portion ecto-entad extend and are directed toward the center of bottom plate.

Further, the lateral sprue 3 is equipped with casting liquid channel and ridge shape protrusion, and ridge shape protrusion is two, Positioned at the inside in casting liquid channel, it is symmetric.

Further, the quantity of the pointed protruding portion is consistent with the quantity of lateral sprue.

Further, two lateral sprues 3 corresponding thereto are directed at the top of each described pointed protruding portion Intersection.

It further, further include center rest, the center rest is two, is set to the bottom of bottom plate, and symmetrically divide It is distributed in the two sides up and down of bottom plate.

It further, further include a locating support, the locating support is arranged in bottom base plate, and passes through the circle of bottom plate The heart, is provided with mounting hole on locating support, and bottom plate is fixed on casting work platform with bolt by mounting hole by when use.

Further, the quantity of the lateral sprue is 6-8.

Further, the diameter of the center casting gate and the ratio of the widest part width size in casting liquid channel are 1:0.8-1.2。

The utility model has the beneficial effects that: multiple and center is arranged on bottom plate by the implementation of the utility model The lateral sprue that casting gate is connected, can to casting liquid play good guiding and shunting function, the outer of bottom plate to The pointed protruding portion of internal stretch is set, good adjusting is played for Homogeneouslly-radiating of the deck store casting when carrying out cooled and solidified Effect, meanwhile, ridge shape protrusion is set in lateral sprue, good control can be played to the flow velocity of casting liquid, prevented The too fast or too slow overall distribution to casting that flows of casting liquid impacts, in addition, bottom plate knot described in the utility model Structure is relatively simple, convenient to carry out, can be promoted the use of in large-scale cabin class or the production process of framework class casting.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 be in the utility model Fig. 1 A-A to view；

In figure: 1- bottom plate, the pointed protruding portion of 11-, 12- center rest, 13- locating support, the center 2- casting gate, the side 3- to Sprue, 31- casting liquid channel, 32- ridge shape protrusion.

Specific embodiment

Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.

As shown in Figs. 1-2, it is a kind of for spacecraft deck store casting floor structure, including bottom plate 1, center casting gate 2 with And lateral sprue 3, wherein bottom plate 1 be it is discoid, center casting gate 2 is set at the center of bottom plate 1；Laterally sprue 3 is It is multiple, it is distributed on bottom plate 1, is connected to center casting gate 2 and extends to the outside of bottom plate 1；The outside of bottom plate 1 is additionally provided with multiple Pointed protruding portion 11, the multiple pointed 11 ecto-entad of protruding portion extend and are directed toward the center of bottom plate 1.

Further, the lateral sprue 3 is equipped with casting liquid channel 31 and ridge shape protrusion 32, and ridge shape protrusion 32 is It two, positioned at the inside in casting liquid channel 31, is symmetric.

Further, the quantity of the pointed protruding portion 11 is consistent with the quantity of lateral sprue 3.

Further, the top of each pointed protruding portion 11 is directed to two lateral sprues 3 corresponding thereto Intersection.

It further, further include center rest 12, the center rest 12 is two, is set to the bottom of bottom plate 1, and right Claim the two sides up and down for being distributed in bottom plate 1.

It further, further include a locating support 13, the locating support 13 is arranged in bottom base plate, and passes through bottom plate 1 center of circle, is provided with mounting hole on locating support 13, and bottom plate 1 is fixed on casting work by mounting hole with bolt when use On platform.
