Automotive brake hub casting and molding device
One, technical field:
Automotive brake hub casting and molding device described in the utility model belongs to the technical field of the formative technology equipment of founding foundry industry.
Two, background technology
The deficiency that has traditional bedded-in moulding now is a full ground sand, poor working environment, labor strength is big, and operant level requires high shortcoming, at these shortcomings, cast member styling apparatus described in the utility model, adopt single independently metallic cavity, replace the drag box in the bedded-in moulding, finish the moulding of die cavity and core with same metal die, and die cavity and core formation seam are cooperated, also still find no identical therewith foundry goods styling apparatus at present.
Three, summary of the invention
The purpose of this utility model provides a kind of clean environment, reduces labour intensity, can work continuously province's sand, the styling apparatus that casting quality is good.
It partly is made up of a metal die two that does not have the metal drum at the end and automotive brake hub up and down, at 2-4 the handle that be provided with of the outside of metal circular bucket or square box symmetry, is convenient to turn over and carries casting pattern.The a plurality of such individual cavity of use replace the sandbox in the bedded-in moulding in the workshop, and die cavity and core formation seam are cooperated.
Adopt the beneficial effect of this device to be: make mill floor not have sand, sanitation and hygiene reduce labour intensity, can save sand amount 80%, cast part good concentricity, and monolateral allowance reduces to 1.5mm by original 5mm, can realize working continuously.
Four, description of drawings
Fig. 1 is casting of automobile braking hub moulding equipment configuration schematic diagram
Among the figure: 1-metal cavitg body, 2-handle, 3-metal die, 4-water rod.
Five, the specific embodiment
Automotive brake hub casting and molding device described in the utility model, its specific embodiment contrast accompanying drawing is further described below: it by metal cavitg body 1 and metal die 3, water rod 4, the moulding mould support is formed, metal cavitg body 1 is made the cylindrical shape or the square box of uncovered of the no end by iron plate, is provided with in the outside of its irony cavity body 1 and is convenient to turn over the handle of lifting 2.Be placed in the workshop by a plurality of identical like this irony cavity body during moulding, realize that casting is produced in batches, during use metal die 3 openings are put into work durm 1 down, the back-up sand compacting; With iron cylinder 1 bottom surface upset upwards, take out mould, make die cavity.When making core work durm body 1 and mould openings are upwards placed, will make the core mold support, water rod 4 and be placed in one, the back-up sand compacting is taken out and is watered rod 4, and the demoulding makes and has the sprue core, has so just finished the sand mold of former and formpiston.Adopt such device, simple in structure, economical and practical, the mill floor cleaning can also save sand 80%, and castability is good.
