Abstract

A wheel cast mould cooling device is characterized in that an upper mould cooling device comprises an upper mould, as well as a large ring air pipe, an upper mould middle ring air pipe, an upper mould small ring air pipe, an upper mould central air pipe and an upper mould rim air barrel pipe which are assembled in the upper mould. When the cooling device is in a running state, the cooling air of the upper mould rim air barrel pipe blows to the corresponding part of the upper mould rim, to quicken cooling speed of the blank rim part; with guaranteed progressive solidification, the air intake flow rate of the upper mould large ring air, the upper mould middle ring air, the upper mould small ring air and the upper mould central air are adjusted inordinately according to different wheel models of the wheels, the cooling time is adjusted appropriately, and cooling parameter of an edge mould and the bottom mould is adjusted correspondingly, so as to quicken the integral productive tempo; and since the upper mould rim air barrel pipe is arranged in the utility model, the rim can be quickly cooled during casting, thereby quickening productive tempo and greatly shortening pressure maintaining time of casting.

Description

A kind of wheel cast equipment for cooling die

Technical field

The utility model relates to a kind of cooling device, particularly a kind of wheel cast equipment for cooling die.

Background technology

When existing low pressure casting is produced wheel, the type of cooling that adopts is generally air-cooled and water-cooled, water-cooled is because the too fast unsuitable crystallization control of cooling velocity, so in low pressure casting, use limitation to some extent, air-cooled general employing ringlet wind, centre circle wind and center wind airduct cool off, and when patrix is cooled off because rim for automobile wheel part broad, and the tubulose solar or lunar halo that adopt in the air channel, can't better partly effectively cool off the patrix wheel rim, cause rhythm of production slow, device resource can not be fully used.

Summary of the invention

The utility model proposes a kind of wheel cast equipment for cooling die at the deficiency that prior art exists, and it is fast that this device has cooling velocity, simple in structure, the characteristics of the blank good mechanical property of output.

The technical solution of the utility model is achieved in that a kind of wheel cast equipment for cooling die, comprise mould cooling apparatus, limit mould cooling apparatus and bed die cooling device, last mould cooling apparatus comprises great circle wind airduct, patrix centre circle wind airduct, patrix ringlet wind airduct, the patrix center wind airduct that is assemblied in the patrix, it is characterized in that: go up mould cooling apparatus and also comprise patrix wheel rim wind wind bucket pipe, patrix great circle wind airduct, patrix centre circle wind airduct, patrix ringlet wind airduct, patrix center wind airduct and patrix wheel rim wind wind bucket pipe are connected with blast pipe respectively.

Described patrix wheel rim wind wind bucket is managed the airtight annular round barrel shape that is shaped as that its feature also is patrix wheel rim wind wind bucket pipe, and patrix wheel rim wind wind bucket pipe is distributed with exhaust vent on the bucket wall of corresponding wheel rim one side.

Because the utility model is provided with patrix wheel rim wind wind bucket pipe, make that wheel rim can be cooled off fast in the casting process, shortened the dwell time of low pressure casting greatly, guaranteed consecutive solidification simultaneously, guaranteed the stable of mechanical performance.

The specific embodiment

Below in conjunction with accompanying drawing structural principle of the present utility model and operation principle are elaborated.

With reference to Fig. 1,2,3, a kind of wheel cast equipment for cooling die, comprise mould cooling apparatus, limit mould cooling apparatus and bed die cooling device, last mould cooling apparatus comprises the great circle wind airduct 2 that is assemblied in the patrix 1, patrix centre circle wind airduct 3, patrix ringlet wind airduct 4, patrix center wind airduct 8, it is characterized in that: go up mould cooling apparatus and also comprise patrix wheel rim wind wind bucket pipe 5, patrix great circle wind airduct 2, patrix centre circle wind airduct 3, patrix ringlet wind airduct 4, patrix center wind airduct 8 and patrix wheel rim wind wind bucket pipe 5 respectively with

blast pipe

9,12,11,10,7 are connected.

Described patrix wheel rim wind wind bucket pipe 5 its features also are the airtight annular round barrel shape that is shaped as of patrix wheel rim wind wind bucket pipe 5, and patrix wheel rim wind wind bucket pipe 5 is distributed with exhaust vent 6 on the bucket wall of corresponding wheel rim one side.

During work, owing to added patrix wheel rim wind wind bucket pipe 5, cooling air blows to patrix wheel rim corresponding position by air outlet 7, make blank wheel rim part cooling velocity accelerate, when guaranteeing consecutive solidification, accelerate for feasible whole productive temp, difference according to the vehicle wheel type, adjusting patrix great circle wind airduct 2 in various degree, patrix centre circle wind airduct 3, patrix ringlet wind airduct 4, the air intake flow of patrix center wind airduct 8 is also suitably adjusted the cooling work time, and the corresponding adjustment limit mould and the cooling parameter of bed die, thereby make that productive temp is accelerated 25%-35% on the basis that guarantees the wheel blanks mechanical performance.

Because the utility model is provided with patrix wheel rim wind wind bucket pipe, make that wheel rim can be cooled off fast in the casting process, thereby accelerated productive temp, shortened the dwell time of low pressure casting greatly.
