Abstract
The utility model relates to a mold tool, in particular to a vacuum large-flux exhaust device for mold. The vacuum exhaust device for mold comprises a static mold sleeve and a moving mold sleeve and is characterized in that the static mold is fixed on the inner side of the static mold sleeve; a moving mold is fixed on the inner side of the moving mold sleeve; a clearance left between the static mold and the moving mold forms an exhaust passage; an air extraction hole is arranged on the end section of the static mold and is connected with vacuum extraction equipment through an exhaust pipe. The mold tool can remove excessive air in the mold, and has the advantages of high product precision, high forming effect, high utilization strength, long service life, reasonable structure, etc.
Description
Technical field
The utility model relates to a kind of mold tooling, especially relates to a kind of mould vacuum high-flow air-exhaust device.
Background technology
As everyone knows, when using mould structure to manufacture a finished product, behind the mould matched moulds in the product shaping process, owing to leave a spot of air between quiet die sleeve and the dynamic model cover, be very easy to cause that product is inner produces situations such as bubble, product shaping effect be bad, caused thus finished product precision low, do not meet specification requirement.Therefore, in the casting process of the sophisticated product in leading-edge fields such as automobile, electronics and aviation, the mold closing mechanism of traditional structure just can't satisfy its precision condition.In this case, research emphasis of the present utility model is exactly how the little air in the mould to be discharged, and improves the forming quality and the precision thereof of product.
Summary of the invention
The utility model mainly is at the technical problem that existing in prior technology can't be got rid of unnecessary air in the mould, product precision is low, forming effect is poor, working strength is low etc., provides a kind of and can get rid of unnecessary air in the mould, product precision height, forming effect height, mould vacuum pumping hardware that working strength is high.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of mould vacuum pumping hardware, comprise quiet die sleeve and dynamic model cover, it is characterized in that described quiet die sleeve inboard is fixed with quiet module, dynamic model cover inboard is fixed with the dynamic model piece, leave the space between described quiet module and the dynamic model piece and form the exhaust passage, quiet module ends is provided with aspirating hole, and described aspirating hole links to each other with vacuum-pumping equipment by blast pipe.Behind the mould matched moulds, during product shaping, the gas between quiet module and the dynamic model piece is extracted out its product precision height, forming effect height by vacuum-pumping equipment through aspirating hole by the exhaust passage.
As preferably, fix by set bolt I between described quiet die sleeve and the quiet module; Logical set bolt II fixes between dynamic model cover and the dynamic model piece.By set bolt with quiet module with the dynamic model piece is separately fixed at quiet die sleeve and dynamic model puts, its working strength height, long service life.
As preferably, described quiet module and dynamic model cover all adopt rigid material to be made into integration.Can use material H13 in principle.
As preferably, described exhaust passage width is 0.3mm---0.7mm.It is rational in infrastructure, and exhaust is abundant.
As preferably, described aspirating hole diameter is 10mm---20mm.It is rational in infrastructure, designs ingenious.
Therefore, the utlity model has the unnecessary air that to get rid of in the mould, product precision height, forming effect height, working strength height, long service life, characteristics such as rational in infrastructure.
Description of drawings
Accompanying drawing 1 is a kind of structure cutaway view of the present utility model.
Accompanying drawing 2 is a kind of partial enlarged drawings at A position in the utility model accompanying drawing 1.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1:
A kind of mould vacuum pumping hardware, comprise quiet die sleeve 1 and dynamic model cover 2, quiet die sleeve inboard is fixed with quiet module 3, dynamic model cover inboard is fixed with dynamic model piece 4, leave the space between quiet module and the dynamic model piece and form exhaust passage 5, quiet module ends is provided with aspirating hole 6, and aspirating hole links to each other with vacuum-pumping equipment 7 by blast pipe 10.Fix by set bolt I8 between quiet die sleeve and the quiet module; Logical set bolt II9 fixes between dynamic model cover and the dynamic model piece.Quiet module and dynamic model cover all adopt rigid material to be made into integration.The exhaust passage width is 0.5mm.The aspirating hole diameter is 15mm.
When installing and using, behind the mould matched moulds, during product shaping, the gas between quiet module and the dynamic model piece is extracted out its product precision height by vacuum-pumping equipment through aspirating hole by the exhaust passage.
