Description

For the double-color mold structure of making high heat conductive insulating composite construction plastic tank radiators

Technical field

The utility model relates to mould applications, especially a kind of for making the double-color mold structure of high heat conductive insulating composite construction plastic tank radiators.

Background technology

The luminescence process of LED illuminating product, to be the process of luminous energy and heat energy by electric energy conversion, and, in the process of this Conversion of Energy, be only luminous energy less than 30% Conversion of Energy, most energy is all converted into heat energy, if and the heat that LED illuminating product sheds does not solve well, will cause like this generation thermal breakdown of LED illuminating product and damage, therefore, it is particularly important that the heat radiation of LED illuminating product just seems. The material of the radiator that at present, on market, LED illuminating product adopts is all almost metal material; But, the heatsink weight of this metalloid material is large, and molding procedure is many in the radiator production of metal material, such as the main process of aluminium radiator just comprises through series of process such as casting, die casting, polishing, polishing, nickel plating, nitrogenize, finally at the skin of metal material, plastics are set again, whole molding cycle is long, and equipment takes up space also very large, and another one aspect is exactly, the heat conductivility of metal radiator is good not enough, also has the bad problem of radiating effect. In order to solve the problem of above-mentioned existence, someone proposes to adopt heat-conducting plastic to replace metal material to produce plastic tank radiators, and owing to making the defect of mould of plastic tank radiators, existing plastic tank radiators unit price is somewhat expensive, therefore cost is higher, is not also promoted, and is also not suitable for a large amount of uses, the speed that is exactly in addition making is slow, and efficiency is not high.

Utility model content

In order to overcome the problems referred to above, the utility model to society provide a kind of cost lower, manufacturing speed faster, output higher for making the double-color mold structure of high heat conductive insulating composite construction plastic tank radiators.

The technical solution of the utility model is: provide a kind of for making the double-color mold structure of high heat conductive insulating composite construction plastic tank radiators, comprise one-shot forming front mould, at least two rear molds that post forming front mould and structure are identical, each described rear mold comprises liftout attachment, described rear mold is arranged on rotating disk and by drive unit and replaces matched moulds with one-shot forming front mould and post forming front mould respectively, when described one-shot forming front mould and rear mold matched moulds, be configured for the one-shot forming die cavity of injection moulding radiator internal layer, when described post forming front mould and rear mold matched moulds, be configured for the outer field post forming die cavity of injection moulding radiator.

As to improvement of the present utility model, described one-shot forming die cavity is connected with main TOP-TIP, enters in one-shot forming die cavity by main TOP-TIP for the sizing material of moulding radiator internal layer.

As to improvement of the present utility model, described post forming die cavity is connected with side TOP-TIP, enters in post forming die cavity by side TOP-TIP for the outer field sizing material of moulding radiator.

As to improvement of the present utility model, described liftout attachment comprises rear mold ejector retainner plate, and described rear mold ejector retainner plate comprises the mouth of a river pin for runner is ejected and the upper ejector retainner plate for the product after post forming is ejected.

The utility model is configured for the one-shot forming die cavity of injection moulding radiator internal layer when having adopted described one-shot forming front mould and rear mold matched moulds, when described post forming front mould and rear mold matched moulds, be configured for the outer field post forming die cavity of injection moulding radiator, so separately internal layer and the skin of injection moulding radiator, just can realize the plastic injection-moulded of the internal layer material different with outer use, so just can reduce costs by freely selecting, and in terms of existing technologies, also ensured radiator one-shot forming, manufacturing speed is faster, and output is higher. Therefore, the utlity model has cost lower, manufacturing speed faster, advantage that output is higher.
