Abstract

The utility model relates to a novel lateral mould used in the manufacture of a car aluminum hub mould by adopting a low-pressure casting method. The novel lateral mould comprises an inside template (1), an upper junction plate (2) connected with the inside template (1), a lower junction plate (3), a lateral junction plate (4) connected with the two sides of the inside template (1), a back template (5), etc. The upper end and the lower end of the lateral junction plate (4) are connected with the upper junction plate (2) and the lower junction plate (3); the upper end and the lower end of the back template (5) are connected with the upper junction plate (2) and the lower junction plate (3); all plates are fixedly connected in a removable way. The utility model is arranged on a standard die set when in use, and is assembled to form the low-pressure casting hub mould together with an upper die and a lower die. When replacing the product, the inside template (1) is only needed to be replaced. The utility model has the advantages that the novel lateral mould effectively solves the problems of the gradient change of the wall thickness of the mould and the ability balance of the heat absorption and the heat dissipation of the mould, thereby enhancing the product quality of the hub; the novel lateral mould also reduces the mould reserve and the fund tying up; the process cycle is shortened, the cost is lowered and so on.

Description

The novel side form of low pressure casting hub mold

One, technical field:

The utility model relates to a kind of mould of producing automotive hub, specifically a kind of novel side form that adopts in the low-pressure casting method production automobile aluminum wheel hub mould.

Two, background technology:

Along with constant development of economy, the improving constantly of living standard, auto industry is also developing rapidly.The main load bearing component that automotive wheel travels as automobile integral body, and wheel hub is as the critical piece of automotive wheel, it is produced and has been subjected to people's attention.The method of producing automobile aluminum wheel hub mainly contains permanent mold casting, the back-pressure casting, and low pressure casting and counter-pressure casting or the like, wherein low pressure casting is owing to the advantage of self is widely used.The employed hub mold of present low pressure casting, its structure is made up of upper die and lower die, side form assembly and standard die set.Used side form assembly is 4 open type side form assemblies, promptly closes as a whole side form assembly by 4 side forms, and every side form all is a monolithic construction.The side form of this monolithic construction exists following shortcoming: 1, owing to produce in the process of wheel hub at low pressure casting, need to consider the heat absorption and the heat-sinking capability of mould, the wall thickness of mould should be different; And wall thickness is inconsistent, when the blank of casting mould, easily produces casting flaw, and particularly the wheel rim shrinkage porosite directly has influence on the product quality that wheel hub is produced; If but the graded of consideration mold wall thickness does not make generation casting flaw when producing cast blank, the then heat absorption of mould, heat-sinking capability can not reach balance, have also influenced the product quality of wheel hub; Thereby to make the balance of heat radiator ability of the graded of mold wall thickness and mould very difficult.2, because side form is the monoblock type side form, and the kind of wheel hub is a lot, then needs to be equipped with a large amount of monoblock type side forms, causes a large amount of fund input and overstocked; Simultaneously, every monoblock type side form all needs the mating surface of itself and upper die and lower die, standard die set is processed, and has also just increased labor content greatly, and the process-cycle is long.

Three, summary of the invention:

The purpose of this utility model is for the low pressure casting hub mold provides a kind of novel side form, and it can solve the equilibrium problem of the heat radiator ability of the graded of mold wall thickness and mould effectively, has guaranteed the quality of side form, improves the product quality of wheel hub; And reduce the deposit of mould and overstocking of fund, shorten the process-cycle, reduce cost.

For achieving the above object, the technical scheme that the utility model is taked is: make to be all-in-one-piece side form into split type side form, promptly the utility model includes inner side template, upper junction plate, lower connecting plate, side connecting plate, dorsal part template etc.Upper junction plate is fixedlyed connected with the upper end of inner side template, lower connecting plate is fixedlyed connected with the lower end of inner side template, side connecting plate is two, fixedlys connected with the both sides of inner side template respectively, fixedlying connected with upper junction plate, lower connecting plate respectively in the two ends up and down of side connecting plate, fixedlys connected with upper junction plate, lower connecting plate respectively in the two ends up and down of dorsal part template.It is detachable fixedly connected that fixedly connected between each plate is.

During use, the utility model is contained on the standard die set, and is assembled into the low pressure casting hub mold by upper junction plate and patrix, lower connecting plate and counterdie.

Because the utility model is designed to split type side form with former monoblock type side form, its upper junction plate, lower connecting plate, side connecting plate, dorsal part template all can be made into the standard component of all size, inner side template can be made according to the needs of wheel hub, when producing different product, only need to change inner side template, so only need to store various inner side template, and do not need to store whole side form, thereby reduce the cost of producing, storing, use.In addition inner side template can be according to the principle of the consecutive solidification of product, in the inner side template design and cast out certain wall thickness gradient, uses the wall thickness of inner side template itself to control the temperature field of mould, reaches the optimum efficiency of production.Therefore the utlity model has the equilibrium problem of the heat radiator ability of the graded that can solve mold wall thickness effectively and mould, guaranteed the quality of side form, improve the product quality of wheel hub; And reduce the deposit of mould and overstocking of fund, shorten the process-cycle, characteristics such as reduce cost.

Four, description of drawings

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1.

Five, the specific embodiment

Accompanying drawing is embodiment of the present utility model, includes inner side template 1, upper junction plate 2, lower connecting plate 3, side connecting plate 4, dorsal part template 5 etc.Upper junction plate 2 is fixedlyed connected with the upper end of inner side template 1, lower connecting plate 3 is fixedlyed connected with the lower end of inner side template 1, side connecting plate 4 is two, fixedlys connected with the both sides of inner side template 1 respectively, fixedlying connected with upper junction plate 2, lower connecting plate 3 respectively in the two ends up and down of side connecting plate 4, fixedlys connected with upper junction plate 2, lower connecting plate 3 respectively in the two ends up and down of dorsal part template 5.It is detachable fixedly connected that fixedly connected between each plate is.

During use, the utility model is contained on the standard die set, and is assembled into the low pressure casting hub mold by upper junction plate 2 and patrix, lower connecting plate 3 with counterdie.When changing the product of producing, only need to change inner side template 1 and get final product.

Therefore the utlity model has the graded that can effectively solve mold wall thickness and the heat absorption of mould looses Heat energy equilibrium of forces problem has guaranteed the quality of side form, improves the product quality of wheel hub; And the minimizing mould Overstocking of deposit and fund, the shortening process-cycle, the characteristics such as reduce cost.
