Abstract
The utility model provides a split combined fusible pattern for a large-sized cartridge receiver structural member. The combined fusible pattern is arranged on an integral tool, and is formed by splicing split wax pieces; each split wax piece is provided with a clamp which is fixed on the integral tool respectively; and the upper part of the integral fusible pattern is provided with a riser and a pouring channel. In the split combined fusible pattern, after an integral wax piece combined tool is combined with a part of a pouring system, each part of each split wax piece is fixed by using the clamps, so that the manufacturing difficulty of the wax pieces is lowered greatly, the sizes of the wax pieces are controlled effectively, and the aim of reducing deformation of castings is fulfilled.
Description
Technical field
The utility model belongs to the precision casting technology field, particularly a kind of large scale computer box structure spare separate assembling fusible pattern.
Background technology
Along with the development of aircraft industry, the manufacturing technology of aero-engine is also at the new step of constantly marching toward.In order to promote the reliability of engine, just the manufacturing of vitals in the engine such as turbine rear housing becomes a difficult problem of being badly in need of solution.Casing spare adopted sheet metal component, forging or foundry goods split manufacturing more in the past, was assemblied into integral body through welding manner then, and this manufacturing approach is more original; Not only operation is many; And have many welding stresses after the integral solder, be easy to generate serious deformation, simultaneously the labor human and material resources.At present; The normal dimensional accuracy control of adopting the integral precision casting technology to realize large-scale complex thin-wall case structure spare in the industry; The a large amount of defectives in cast crackle, shrinkage cavity and the Non-Destructive Testing of foundry goods have been solved; But because of case structure spare diameter dimension is big, wall thickness is very little, it is extremely difficult to cause fusible pattern to be made, and the distortion after the foundry goods casting simultaneously is also still relatively serious.
Summary of the invention
Shortcomings and deficiencies to existing large scale computer box structure spare manufacturing technology; The utility model provides a kind of large scale computer box structure spare separate assembling fusible pattern; This combined type fusible pattern is arranged on the whole frock; Fusible pattern is made up of split type wax spare splicing, and each split type wax spare is respectively arranged with clamps on whole frock, and the top of whole fusible pattern is provided with rising head, running channel.
During manufacturing; Be split type wax spare according to the diameter dimension of treating mo(u)lded piece and design feature with fusible pattern is prefabricated; Each split type wax spare is spliced into whole fusible pattern successively; Again whole fusible pattern is placed on the composite entity frock, and each split type wax spare is provided with clamps respectively, on the top of whole fusible pattern rising head, running channel are set again.
The large scale computer box structure spare separate assembling frock fusible pattern that uses the utility model to provide; After carrying out the combination of wax spare entire combination frock and part running gate system; The each several part of wax spare is fixed by anchor clamps; The manufacture difficulty of wax spare reduces greatly, and wax spare size has also obtained effective control, thereby reaches the purpose that reduces casting deformation.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Embodiment 1:
The separate assembling fusible pattern of present embodiment; Treat that mo(u)lded piece is a symmetrical structure; The combined type fusible pattern a of this part is arranged on the whole frock b; Fusible pattern a is made up of 1/8 wax spare I and the splicing of 1/8 wax spare II, and each split type wax spare is respectively arranged with anchor clamps c and is fixed on the whole frock b, and the top of whole fusible pattern a is provided with rising head, running channel.
When making combinations thereof formula fusible pattern a, prefabricated two split type wax spare 1/8 wax spare I of elder generation and 1/8 wax spare II are like Fig. 1, shown in Figure 2; Two 1/8 wax spares that make are duplicated three parts, and two 1/8 wax spares are combined as 1/4 wax spare more successively, and are as shown in Figure 3; Four 1/4 wax spares that combine are spliced into whole fusible pattern a on whole frock b, and the each several part of the fixing split type wax spare of clamp structures such as cushion block, screw is set respectively on whole frock b, and rising head and coupling part cross gate are set on the top of fusible pattern a again.
