Abstract
A kind of powder metallurgy water-cooled former, comprise internal mold and external mold, it is characterized in that: described external mold and internal mold are inlayed by hot jacket and be combined into one, and the medial surface of external mold offers tank, offer the pipeline that the Cooling Water that is connected with outer water tube passes in and out in external mold, pipeline is communicated with tank.The utility model structure is simple, it is ingenious to design, and takes away mold heat in pressing process, keep pressing process to stablize by inside and outside water circulation; And manufacture easy to process, cost is low, good seal performance, thicker, that density is higher powder metallurgy product can be suppressed smoothly, there is very strong practicality, be worth large-scale popularization to use.
Description
Technical field
The utility model belongs to powder metallurgy manufacturing technology field, relates to a kind of mould, particularly relates to a kind of powder metallurgy water-cooled former.
Background technology
Powder metallurgy be with metal or with metal dust as raw material, through being shaped and sintering, manufacture the technology of metal material, compound and all kinds goods, be widely used in every field, because powder metallurgy has unique chemical composition and machinery, physical property, be that traditional casting method cannot obtain, can be used for manufacturing the various powdered metal parts such as automobile, motorcycle, textile machine, electric tool, hardware & tools, electrical equipment.
Along with the development of automotive engineering, require higher than ever to the powder metallurgy product for auto parts and components, such as high density product, substitute some originally with the part that steel manufacture.Also to aspire for stability to manufacture process, the good product consistency produced like this.So, in shaping suppression process, easily cause iron powder to lump because mold temperature is higher, and also affect the lubricant effect of lubricant in material powder, die wear is aggravated, and product quality cannot ensure, therefore avoids overheated iron powder caking, mould self plucking of causing of mould necessary.
The existing patent No. is the Chinese utility model patent " a kind of water-cooled mold for powder metallurgy " of CN201120421236.4, comprise forming female die, be arranged on the former jacket of forming female die outside, the outer wall of described forming female die is provided with cooling structure, described cooling structure comprises water inlet, water out, and is arranged on the helical duct between water inlet and water out.This mould is provided with cooling structure, but needs the passage offering bending, processes cumbersome, and sealing between former and former jacket is also not ideal enough, cannot ensure the sealing in water route.
Summary of the invention
Technical problem to be solved in the utility model be provide for the above-mentioned state of the art a kind of rational in infrastructure, manufacture powder metallurgy water-cooled former that is easy to process, good seal performance.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of powder metallurgy water-cooled former, comprise internal mold and external mold, it is characterized in that: described external mold and internal mold are inlayed by hot jacket and be combined into one, the medial surface of external mold offers tank, offer the pipeline that the Cooling Water that is connected with outer water tube passes in and out in external mold, pipeline is communicated with tank.
As improvement, described pipeline comprises inlet channel and outlet conduit, the first through hole as inlet channel is laterally offered above the side, tank of external mold, the middle part of the first through hole offers water inlet downwards, at the opposite side of external mold, horizontal second through hole offered as outlet conduit in below of tank, the middle part of the second through hole offers delivery port downwards, and is provided with link block in the outer end of the first through hole and the second through hole.
As improvement, described tank is spiral tank, and the tangent plane of tank is semicircular arc.
As improvement, the seam crossing that described internal mold matches with external mold adopts glue sealing.
Compared with prior art, the utility model has the advantage of: structure is simple, it is ingenious to design, and takes away mold heat in pressing process, keep pressing process to stablize by inside and outside water circulation; And manufacture easy to process, cost is low, good seal performance, thicker, that density is higher powder metallurgy product can be suppressed smoothly, there is very strong practicality, be worth large-scale popularization to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, the powder metallurgy water-cooled former of the present embodiment, comprise internal mold 2 and external mold 1, internal mold 2 uses YG8 material, price but not easy to wear, and external mold 1 adopts 40Cr steel, external mold 1 and internal mold 2 are inlayed by hot jacket and are combined into one, the medial surface of external mold 1 offers tank 11, and offer the pipeline that the Cooling Water that is connected with outer water tube passes in and out in external mold 1, pipeline is communicated with tank; Pipeline comprises inlet channel 12 and outlet conduit 13, the first through hole as inlet channel 12 is laterally offered above the side of external mold 1, tank 11, the middle part of the first through hole offers water inlet downwards, at the opposite side of external mold 1, horizontal second through hole offered as outlet conduit 13 in below of tank 11, the middle part of the second through hole offers delivery port downwards, and be provided with link block 3 in the outer end of the first through hole and the second through hole, be convenient to external mold 1 and process; Tank 11 is spiral tank, and the tangent plane of tank 11 is semicircular arc, and the seam crossing that internal mold 1 matches with external mold 2 adopts glue 4 to seal.
During manufacture, external mold 1 internal diameter and internal mold 2 external diameter control certain magnitude of interference, by heating volumetric expansion to external mold 1, embedding internal mold 2, ensureing necessary enclasping force, avoid internal mold 2 in pressing process to deviate from after cooling between two moulds; External mold 1 medial surface design spiral tank, tank 11 has arc radius, radius too weep amount is unfavorable for the heat taking away former generation in time, the waterway circulating passage be connected with outer water tube is designed in external mold 1, in the seam that internal mold 2 coordinates with external mold 1, adopt glue 4 to seal, ensure that waterway circulating is airtight.
The utility model is good through implementing result of use, and easily manufactured, obtained large-scale popularization.
