Abstract

The utility model relates to the technical field of vehicle wheel hub manufacturing, in particular to a wheel hub die with a rapid cooling structure. The wheel hub die with the rapid cooling structure comprises an upper die, a lower die and a side die. A wheel hub formed by die assembly of the upper die, the lower die and the side die forms a die cavity. The wheel hub die further comprises a cooling device for cooling the upper die and the lower die, and the outer surface of the lower die is provided with a pit recessed towards a lower die body. The cooling device comprises an upper die cooling pipe for conveying cooling mediums to the surface of the upper die to cool the upper die and a lower die cooling pipe for conveying cooling mediums to the lower die to cool the lower die. A cooling medium outlet end of the lower die cooling pipe is positioned in the pit. The die can be rapidly cooled, the problem of poor quality caused by shrinkage porosity of the formed wheel hub is solved, and the service life of the wheel hub is prolonged.

Description

Hub mold with Quick cooling structure

Technical field

The utility model relates to vehicle wheel hub manufacturing technology field, is specifically related to a kind of hub mold with Quick cooling structure.

Background technology

Wheel hub is for assembling the parts of rubber tyre, the moulding by casting technique, the hub mold used comprises patrix, side form, and counterdie, counterdie is mainly used in the shape casting to spoke on wheel hub, in casting process, because cast raw material has certain high temperature, can transfer heat to mould, thereby need to carry out cooling to mould, if cooling velocity is slow, the wheel hub of producing just there will be the shrinkage porosite phenomenon, so-called shrinkage porosite refers to that the zone of foundry goods final set does not obtain feeding formation dispersion and the tiny shrinkage cavity of liquid metal or alloy, the Quality Down of wheel hub like this, flaw appears, relatively also reduced the service life of wheel hub.

Summary of the invention

For above-mentioned technical problem, the utility model provides a kind of hub mold with Quick cooling structure, and it can carry out mould cooling fast, and the quality problems that cause the shrinkage porosite phenomenon appears and in the wheel hub of avoiding moulding, extends the service life of wheel hub.

The technical scheme solved the problems of the technologies described above is as follows:

Hub mold with Quick cooling structure, comprise by upper die and lower die and side form, the wheel hub shaping mold cavity formed after upper die and lower die and side form matched moulds, also comprise upper die and lower die are carried out to cooling cooling device, outer surface at counterdie is provided with to the pit of lower mold body depression, above-mentioned cooling device comprises to patrix surface transport cooling medium patrix is carried out to cooling patrix cooling tube, and carry cooling medium to carry out cooling counterdie cooling tube to counterdie to counterdie, the cooling medium port of export of described counterdie cooling tube is in pit.

Further, the outer surface at described counterdie is provided with a plurality of pits to the lower mold body depression.In each pit, equal correspondence arranges a counterdie cooling tube like this, the cooling medium of discharging from the counterdie cooling tube port of export enters pit and carries out cooling to counterdie, cooling medium also can carry out brief stay in pit, after fully to the counterdie cooling, extruded by the cooling medium that continues to enter in pit, improve like this service efficiency of cooling medium.

Further, described a plurality of pit be take the center of counterdie and is arranged in the surface of counterdie as the center of circle.

Further, described pit is arranged between the spoke mould of counterdie, does not affect like this thickness at counterdie spoke place.

Adopted such scheme, outer surface at counterdie is provided with to the pit of lower mold body depression, the cooling medium port of export of counterdie cooling tube is in pit, the cooling medium of discharging from the counterdie cooling tube like this can enter in pit, realization is cooling to lower mold body, cooling medium can carry out brief stay in pit, after fully to the counterdie cooling, by the cooling medium that continues to enter in pit, extruded, improve like this service efficiency of cooling medium, also accelerated the cooling velocity to counterdie, the quality problems that cause the shrinkage porosite phenomenon appears and in the wheel hub of having avoided moulding, extend the service life of wheel hub, the pit here also can be realized the alleviating of counterdie weight is convenient to the erection of counterdie, has also reduced the materials'use of manufacturing counterdie, has saved resource.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

The structural representation that Fig. 2 is counterdie;

In figure, 1 is patrix, and 2 is counterdie, and 3 is side form, and 4 is shaping mold cavity, and 5 is pit, and 6 is the spoke mould, and 7 is the patrix cooling tube, and 8 is the counterdie cooling tube.

The specific embodiment

With reference to Fig. 1,2, hub mold with Quick cooling structure, comprise by patrix 1, counterdie 2 and side form 3, the wheel hub shaping mold cavity 4 formed after upper die and lower die and side form matched moulds, also comprise upper die and lower die are carried out to cooling cooling device, be provided with a plurality of pits 5 to the lower mold body depression at the outer surface of counterdie, a plurality of pits be take the center of counterdie and are arranged in the surface of counterdie as the center of circle, and pit is arranged between the spoke mould 6 of counterdie; Cooling device comprises to patrix surface transport cooling medium patrix is carried out to cooling patrix cooling tube 7, patrix cooling tube 7 arranges many, quickening is cooling to patrix, and carry cooling medium to carry out cooling counterdie cooling tube 8 to counterdie to counterdie, the cooling medium port of export of counterdie cooling tube is in pit.

Current hub mold is the thinner thickness of patrix, the medium of discharging by the patrix cooling tube just can carry out patrix cooling fast, and the thickness of counterdie is thicker, thereby dig pit at the lower surface of counterdie, cooling medium that the counterdie cooling tube is discharged is contacted carry out cooling with the inside of counterdie, cooling effectiveness is good, and speed is fast; Also can on both, dig pit if certainly the thickness of patrix and side form is thicker, correspondence that the cooling tube port of export is set is cooling fast in wherein carrying out.

Claims (4)
