Embodiment 1

[0041] like Figure 2-Figure 4 As shown, this embodiment provides a deformed adapter, including an adapter body 1, the inner contour of the adapter body 1 is matched with the outer contour of the core mold skeleton 100, the adapter body 1 is sleeved on the core mold skeleton 100, and is located in the core mold skeleton 100. Between the core mold skeleton 100 and the outer shell 200 , the adapter body 1 is made of elastic material, and can deform and shrink when the core mold skeleton 100 expands at high temperature, so as to prevent the outer shell 200 from being deformed.

[0042] In the deformed adapter of this embodiment, an adapter body 1 is arranged between the core mold skeleton 100 and the outer shell 200 , and the adapter body 1 is attached to the core mold skeleton 100 . The contour is adapted, and the deformation adapter is made of elastic material. When the outer shell 200 and the core mold skeleton 100 are cured at high temperature, the core mold skeleton 100 is t...

Embodiment 2

[0055] see Figure 5-Figure 12 As shown, this embodiment provides a mold for manufacturing the above-mentioned deformed adapter. The mold includes a base 5, a movable mold 4 and a fixed mold 3 with a gate 6, wherein: the base 5 is fixed and supported on the movable mold 4 and the fixed mold 3. The bottom of the fixed die 3, among the movable die 4 and the fixed die 3, one of the inner profiles is adapted to at least part of the convex surface of the adapter body 1, and the other inner profile is compatible with at least part of the concave surface of the adapter body 1 Matchingly, the movable mold 4 and the fixed mold 3 are connected to form a cavity. see Image 6 As shown, the fixed mold 3 is provided with a pouring gate 6 for pouring the silicone rubber liquid into the cavity.

[0056] Wherein, the above-mentioned "at least part of the adapter body 1" refers to a piece of arc-shaped sheet, that is, the above-mentioned mold is used to manufacture a piece of arc-shaped sheet...

Abstract

The invention provides a deformation adapter and a mold for manufacturing the deformation adapter, relates to the technical field of solid rocket engine devices, and solves the technical problem that an outer shell deforms due to expansion deformation of a core mold framework in a high-temperature environment. The deformation adapter comprises an adapter body, the inner contour of the adapter body is matched with the outer contour of the core mold framework, the adapter body is arranged on the core mold framework in a sleeving mode and located between the core mold framework and the outer shell, and the adapter body is made of elastic materials and can deform and contract when the core mold framework expands at the high temperature so as to prevent the outer shell from deforming. When the outer shell and the core mold framework are cured at a high temperature, the core mold framework is heated to expand and deform, the adapter body bears the pressure of the core mold framework at the high temperature, can deform and shrinks after being heated, the deformation amount of the core mold framework can be reduced, the outer shell is prevented from being deformed by the pressure of the core mold framework, and smooth production and assembly are guaranteed.

Description

technical field [0001] The invention relates to the technical field of solid rocket motor devices, in particular to a deformation adapter and a mold for manufacturing the deformation adapter. Background technique [0002] Currently, see figure 1 shown, figure 1 It is a schematic structural diagram of the core mold of a rocket engine in the prior art; the core mold of a large solid rocket motor sequentially includes a core mold skeleton, a gypsum layer and an outer shell from the inside to the outside. The metal layer is used to improve the structural strength. The outer shell is usually made of carbon fiber. The carbon fiber outer shell needs to undergo 5 pre-curing and 1 final curing during the process of winding on the gypsum layer. [0003] The applicant found that the prior art has at least the following technical problems: due to the different deformation amounts caused by the thermal expansion coefficients of different materials when the outer shell and the core mold...
