Abstract

The utility model relates to a die-casting mould of an LED heater radiator. The die-casting mould comprises a front mould board, a front mould core, a rear mould board, a rear mould core, a thimble and a thimble fixing board, wherein the front mould core is installed on the front mould board; the rear mould core is installed on the rear mould board; the thimble is installed on the thimble fixing board; a cavity of a molding LED heat radiator component and a pouring channel connected with the cavity are formed on parting surfaces of the front and rear mould cores respectively; an embedding fixing board is installed between the thimble fixing board and the rear mould board; and the embedding fixing board is provided with an embedding block which is matched with the cavity for forming a product. According to the die-casting mould provided by the utility model, via arranging the embedding fixing board between the thimble fixing board and the rear mould board, not only the embedding block can be arranged on the embedding fixing board, but also the rear mould board and the rear mould core installed on the rear mould board can be thickened, so that thicker products can be formed by die casting by the die-casting mould; and moreover, the popularization of the products is also facilitated by the arrangement of an elastic piece. The production efficiency is high and the quality of the product is good.

Description

A kind of die casting of LED radiator

Technical field

The utility model relates to the mould technical field, specifically is meant a kind of die casting of LED radiator.

Background technology

LED radiator 10 is complex structure not only; Cause the die casting difficulty, and the general die-cast part of LED radiator 10 aspect ratios is big, all compares difficulty when carrying out die casting and releasing product; Shown in accompanying drawing 1, thereby general die casting is not suitable for die casting LED radiator 10 products.

Summary of the invention

But the technical problem that the utility model will solve provides the die casting of the big LED radiator of a kind of die casting thickness.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of die casting of LED radiator; Comprise front template, preceding die, rear pattern plate, back die, thimble and thimble fixed head; Preceding die is arranged on the front template; Back die is arranged on the rear pattern plate, and thimble is arranged on the thimble fixed head, on the die joint of die behind the front mould Renhe, is respectively equipped with the die cavity and the running channel that is connected with die cavity of moulding LED heat sink assembly; Be provided with the fixed head of inserting between said thimble fixed head and the rear pattern plate, the fixed head of inserting is provided with and cooperates inserting of shaped article with die cavity.

As the optimization to such scheme, above-mentioned inserting is provided with elastic component.

As the further optimization to such scheme, above-mentioned elastic component is rubber blanket or spring.

The utlity model has following remarkable result:

The utility model die casting is through being provided with the fixed head of inserting between thimble fixed head and rear pattern plate; Not only can on the fixed head of inserting, be provided with and insert; And can make bigger that rear pattern plate and the thickness of being located at the back die on the rear pattern plate can do, thus make this die casting can the bigger product of die casting thickness, and the setting of elastic component has also made things convenient for the release of product; Production efficiency is high, good product quality.

Description of drawings

Accompanying drawing 1 is a LED radiator perspective view;

Accompanying drawing 2 is the utility model decomposition texture sketch mapes.

The specific embodiment

For the ease of it will be appreciated by those skilled in the art that below combination principle figure and embodiment are explained in further detail the utility model.

Shown in accompanying drawing 2, the die casting that present embodiment disclosed is used for the bigger parts product of molding thickness, for example LED radiator; LED is installed in the radiator, and this die casting includes front template 1, preceding die, rear pattern plate 3, back die 4, thimble and thimble fixed head 6, and preceding die is arranged on the front template 1; Back die 4 is arranged on the rear pattern plate 3; Thimble is arranged on the thimble fixed head 6, on the die joint of die 4 behind the front mould Renhe, is respectively equipped with die cavity 41, is connected with running channel 7 on the die cavity 41.

In the present embodiment; Between thimble fixed head 6 and rear pattern plate 3, be provided with the fixed head 8 of inserting; On the fixed head 8 of inserting, be provided with and insert 81; Aqueous sizing material injects die cavity 41 with the 81 moulding LED radiator products 10 of inserting through running channel 7, and thimble fixed head 6 drives thimble LED radiator product 10 is released under the driving of driving mechanism.

For more convenient release LED radiator product 10; Insert and 81 be provided with elastic component 9; Elastic component 9 can be rubber blanket or spring, and when front template 1 and rear pattern plate 3 close when closing, front template 1 drives rear pattern plate 3 and moves to fixed head 8 directions of inserting under the driving of driving mechanism; Rear pattern plate 3 compression elastic pieces 9 simultaneously close until front template 1 and rear pattern plate 3 and to close completion; When aqueous sizing material needs die sinking through running channel 7 injection die cavities 41 behind the 81 moulding LED radiator products 10 of inserting; Front template 1 resets next time in the driving of driving mechanism and puts, and front template 1 was opened with rear pattern plate in 3 minutes, and LED radiator product 10 is still on the die 4 of back; Under the elastic force effect of elastic component 9 self; Elastic component 9 answer positions are pushed rear pattern plate 3 open, drive rear pattern plate 3 and move toward front template 1 directions, 81 separate with LED radiator product 10 thereby can make to insert; Last under the effect of thimble, release LED radiator product 10.

The utility model die casting is through being provided with the fixed head 8 of inserting between thimble fixed head 6 and rear pattern plate 3; Not only can on the fixed head 8 of inserting, be provided with and insert 81; And can make bigger that rear pattern plate 3 and the thickness of being located at the back die 4 on the rear pattern plate 3 can do, thus make this die casting can the bigger product of die casting thickness, and the setting of elastic component 9 has also made things convenient for the release of product; Production efficiency is high, good product quality.

The foregoing description is the preferred version that the utility model is realized; And it is non-limiting exhaustive; The utility model can also have other variations under same idea; Need to prove that under the prerequisite that does not break away from the utility model inventive concept, any conspicuous replacement is all within protection domain of the present invention.
