Abstract
A kind of sandbox of negative pressure casting, comprise casing and dividing plate, described dividing plate is positioned at box house bottom surface and side, described separator edge and welding box body are fixed together, described baffle surface is provided with multiple through hole, described bottom half and side are provided with negative-pressure ward pipeline, and described negative-pressure ward pipeline is connected by gap with the through hole of baffle surface.The beneficial effects of the utility model are: add insulation sand after mould being put into this casing and cover, building the rear principle utilizing porous to aspirate makes insulation sand produce uniform negative pressure, extrusion die, die surface uniform force, connect more tight, and be conducive to the eliminating of bubble in mould, make the steel ball of casting organize more even compact, mechanical performance is better.
Description
Technical field
The utility model relates to a kind of negative pressure casting technology, and specifically for making cast structure more even compact, mechanical performance is better.
Background technology
Current a lot of manufacturer is in order to ensure the cast member better quality of producing, many employings negative pressure casting technology is cast, and puts into sandbox by mould, adds insulation sand and covers, building the rear principle of suction that utilizes makes insulation sand produce negative pressure, and extrusion die reaches a kind of technology improving casting quality.Because existing sandbox aspirating hole quantity is single, therefore when vacuumizing, die face pressure points to a point, and in mould, foundry goods institute pressurized is uneven, Density inhomogeneity when causing foundry goods shaping, and compactness is inadequate, and performance does not reach requirement.
Summary of the invention
In order to solve the problem, the utility model provides a kind of structure of improvement for negative pressure casting sandbox.
The technical scheme in the invention for solving the above technical problem is:
A kind of negative pressure casting sandbox, comprise casing and dividing plate, described casing material is cast iron, and described casing is used for splendid attire mould, and described dividing plate is sheet iron plate, and described dividing plate is positioned at box house bottom surface and side, and described separator edge and welding box body are fixed together.
As preferred embodiment, described bottom half and side are provided with multiple negative-pressure ward pipeline.
As preferred embodiment, described casing rear and front end is provided with auxiliary carrying handrail, and the transport being convenient to casing uses.
As preferred embodiment, described baffle surface is provided with through hole, and described through hole has multiple and is evenly distributed on baffle surface.
As preferred embodiment, described through hole is connected by gap with negative-pressure ward pipeline.
The beneficial effects of the utility model are: add insulation sand after mould being put into this casing and cover, building the rear principle utilizing porous to aspirate makes insulation sand produce uniform negative pressure, extrusion die, die surface uniform force, connect more tight, and be conducive to the eliminating of bubble in mould, make the steel ball of casting organize more even compact, mechanical performance is better.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the present invention is further qualified:
As Figure 1-3, a kind of negative pressure casting sandbox, comprise casing 1 and dividing plate 2, described casing material is cast iron, described casing 1 is for splendid attire mould, described dividing plate 2 is sheet iron plate, described dividing plate 2 is positioned at casing 1 inner bottom surface and side, together with described dividing plate 2 edge is welded and fixed with casing 1, bottom described casing 1 and side is provided with multiple negative-pressure ward pipeline 3, described casing 1 rear and front end is provided with auxiliary carrying handrail 4, the transport being convenient to casing uses, described dividing plate 2 surface is provided with through hole 5, described through hole 5 has multiple and is evenly distributed on dividing plate 2 surface, described through hole 5 is connected by gap with negative-pressure ward pipeline 3.
The beneficial effects of the utility model are: add insulation sand after mould being put into this casing and cover, building the rear principle utilizing porous to aspirate makes insulation sand produce uniform negative pressure, extrusion die, die surface uniform force, connect more tight, and be conducive to the eliminating of bubble in mould, make the steel ball of casting organize more even compact, mechanical performance is better.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
