Abstract
The present invention discloses a method and metal mold for casting radiator, and features that the mold consists of side board, bottom board, sprue, clamping metal sheet, adjustable spacing strip, screw bolt, etc. The casting process includes the steps of setting radiating fins inside the clamping metal sheets, locking the side boards with the screw bolts, pouring high temperature aluminum liquid, cooling, demolding, and eliminating clamping metal sheets. By means of altering and replacing different mold parts, radiators of different types and sizes may be produced.
Description
Technical field:
The present invention relates to a kind of manufacture method of radiator, particularly relate to a kind of method and mould that adopts metal type cast radiator.
Background technology:
At present, the radiator major part on the market all is to adopt the pressure casting process one-shot forming.Because be subjected to the restriction of plant equipment and extrusion ratio, the ratio between the whole length and width in gear piece thickness, length, density and the cross section of radiator is restricted, and does not satisfy the various demand of market to the specification of radiator.And one-time formed radiator, a mold can only be suppressed a kind of product of specification, and the remodeling cycle is long, the expense height.The radiator of producing with casting method is in a small amount also arranged, the patent No. is the radiator of 97108973.6 inventions, its advantage is to satisfy various lengths, thick collocation requirement, but also there is certain defective: 1. in the high temperature casting cycle, filler is easy to generate leakage aluminium with the gap of heat radiation gear piece, make after its moulding the contact-making surface of gear piece and radiating bottom plate very coarse, influence its radiating effect and attractive in appearance; 2. this opening casting method, after cast molding, the backplate surface of its radiator is uneven, and easily causes the core shrinkage porosite, and interior tissue is inhomogeneous.
Summary of the invention:
Technical problem to be solved by this invention provides and a kind ofly can effectively overcome above-mentioned defective, produces a mold of radiator with the method for metal type cast, and can utilize and move or various sizes that more each several part of mold exchange changes radiator.The technical solution adopted for the present invention to solve the technical problems is, a kind of method of metal type cast radiator, and its characteristics are: this method comprises the following steps:
A. as requested, be ready to thickness, length, the suitable heat radiation gear piece of width;
B. behind the mould and die preheating,, spray heat-insulation and heat-preservation demoulding coating in metal part with the contact of aluminium liquid;
C. the gear piece that will dispel the heat is arranged in order in the metal intermediate plate of mould, sees Fig. 1, and makes the top of heat radiation gear piece expose metal intermediate plate certain-length, forms certain casting space above the heat radiation gear piece;
D. utilize screw mandrel locking limit mould.
E. before injecting high temperature aluminum liquid, sprinkle flowability powder preferably equably at casting space, its effect is: high temperature aluminum liquid is after injecting mould, evenly flow, the gear piece of the radiator that processes is contacted well with base plate, and technology is attractive in appearance, increases its radiating effect;
F. cover the cast gate of mould, high-temperature liquid state aluminium is injected in the mold cavity from cast gate, very fast the dazzling with the heat radiation gear piece of high-temperature liquid state aluminium is connected into one like this;
G. after the cooling, from mould, take out the radiator of moulding, remove the metal intermediate plate between its heat radiation gear piece, then made radiator;
H. the metal intermediate plate is put back in the mould, the gear piece that will dispel the heat again is arranged in the metal intermediate plate, so just can regenerate and produce next product.
By the employed equipment of method of above-mentioned a kind of metal type cast radiator, its characteristics are: described mould mainly is made of Bian Mo and die bottom plate, cast gate, metal intermediate plate, adjustable filler strip, screw mandrel etc.Die bottom plate is connected with adjustable filler strip by set screw, is adjustable space between adjustable filler strip and die bottom plate, and the size of adjustable space is the height of decision radiator and the key factor of substrate thickness.Be equipped with the metal intermediate plate on it, the thickness of metal intermediate plate is for forming heat radiation gear piece tooth pitch, and the top of metal intermediate plate and the space between the rising head are casting space, and limit mould bypass is crossed screw mandrel and linked to each other with holder on the die bottom plate, and the end of screw mandrel is provided with handle.
Owing to adopt such scheme, be not difficult to draw the present invention and have following beneficial effect, the present invention is rational in infrastructure, is skillfully constructed, and by moving or the each several part of change mould is made the radiator of different size, the replacement cycle is short, and expense is few; Mould can move flexibly, processes the spacing of different radiator gear pieces, and the metal intermediate plate of changing different-thickness is just passable, radiator after the machine-shaping, technology is attractive in appearance, and is functional, area of dissipation is big, density is high, more can satisfy the demand in market, has promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the present invention is described in further detail.
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Among the figure, the employed mould of a kind of method of low-pressure casting radiator, mainly constitute by limit mould 1 and die bottom plate 2, cup 9 is stamped in the top of limit mould 1, its rim of a cup below is a runner 14, runner 14 belows are rising head 10, and die bottom plate 2 is connected with adjustable filler strip 5 by set screw 3,2 of adjustable filler strip 5 and die bottom plates are adjustable space 4, be equipped with metal intermediate plate 12 on it, the thickness of metal intermediate plate 12 is for forming heat radiation gear piece tooth pitch 13, and the space between the top of metal intermediate plate 12 and the rising head 10 is a casting space 11, mould 1 bypass in limit is crossed screw mandrel 6 and is linked to each other with holder 7 on the die bottom plate 2, and the end of screw mandrel 6 is provided with handle 8.
