Abstract
The utility model discloses a kind of radiating structure formula injection mold, comprise cover half mold insert, the insert coordinated with described cover half mold insert, dispel the heat pin, heat dissipation film; After matched moulds, between described cover half mold insert and described insert, form die cavity; Described die cavity arranged outside has the multiple heat radiation pins coordinated with described die cavity, and described heat radiation pin is positioned at described cover half mold insert and insert, and described heat radiation pin rear end is provided with radiation water channel; Described die cavity is pointed in described heat radiation pin front end, is provided with radiating groove, is covered with described heat dissipation film in described radiating groove between described heat radiation pin and described die cavity, and described heat radiation pin front end contacts with described heat dissipation film.The utility model is rational in infrastructure, is derived by the heat in die cavity by heat radiation pin, turn avoid heat radiation pin simultaneously and causes white trace to moulding surface, improve the surface quality of moulding, improve ratio of briquetting and the quality of moulding, reduce the cool time of moulding, improve production efficiency.
Description
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of radiating structure formula injection mold.
Background technology
Injection mold is widely used in plastic product processing industry.Injection mold is generally adapted to thermoplastic hot briquetting.Utilize the hot melt principle of thermoplastic, the plastics of melting are injected in the die cavity of mould by injection machine, then cooling and shaping, open mould and take out plastic product.
Injection moulding, as a kind of important plastic processing, is widely applied in industrial circle.Along with the use of plastic products is increasingly extensive, people propose stricter requirement to its surface quality, intensity and Shooting Technique; For this reason, injection mold is needed must to possess good processability.
In existing mold production process, generally by arranging radiation water channel in injection mold inside, moulding is cooled, but for some baroque mouldings or the moulding having structure of caving in, often cannot be cooled by radiation water channel, owing to being heated, uneven meeting causes moulding to be out of shape; And also have injection mold to be cooled by heat radiation pin for these mouldings, but directly contacting moulding by heat radiation pin dispels the heat, and often causes white trace on moulding surface, affects moulding surface quality.
Utility model content
Utility model object: the utility model solves the problems referred to above, provides a kind of radiating structure formula injection mold.
Technical scheme: a kind of radiating structure formula injection mold, comprises cover half mold insert, the insert coordinated with described cover half mold insert, dispels the heat pin, heat dissipation film; After matched moulds, between described cover half mold insert and described insert, form die cavity; Described die cavity arranged outside has the multiple heat radiation pins coordinated with described die cavity, and described heat radiation pin is positioned at described cover half mold insert and insert, and described heat radiation pin rear end is provided with radiation water channel; Described die cavity is pointed in described heat radiation pin front end, is provided with radiating groove, is covered with described heat dissipation film in described radiating groove between described heat radiation pin and described die cavity, and described heat radiation pin front end contacts with described heat dissipation film.
As a kind of preferred version of the present utility model, the degree of depth of described radiating groove is identical with the thickness of described heat dissipation film.
As a kind of preferred version of the present utility model, the thickness of described heat dissipation film is 3 ~ 5mm.
As a kind of preferred version of the present utility model, described heat dissipation film is composited by asbestos stratum reticulare and aluminium foil layer, and described aluminium foil layer contacts with described die cavity.
As a kind of preferred version of the present utility model, the thickness of described aluminium foil layer is 2 times of described asbestos stratum reticulare.
As a kind of preferred version of the present utility model, described heat radiation pin is made up of aluminum alloy material.
Beneficial effect: the utility model compared with prior art, its advantage is, the utility model is rational in infrastructure, by heat radiation pin, the heat in die cavity is derived, turn avoid heat radiation pin simultaneously and cause white trace to moulding surface, improve the surface quality of moulding, improve ratio of briquetting and the quality of moulding, reduce the cool time of moulding, improve production efficiency.
