Abstract
The utility model relates to the technical field of injection forming mold, especially a kind of thin-walled lid injection forming mold is related to, described patrix is provided with sprue, sprue is communicated with the runner be located in patrix, runner is communicated with corresponding sprue respectively, described patrix is at least provided with the groove of more than six, in groove, is provided with upper cavity; At least two sprues are evenly equipped with at the bottom of the chamber of described upper cavity.Advantage is: mold integral is relatively light and handy, and disposablely produces multiple box body, and production efficiency is high, the advantage of lower cost of mfg. moulding die, and shaping product is relatively thin and quality is extremely light.
Description
Technical field
The utility model relates to the technical field of injection forming mold, especially relates to a kind of thin-walled lid injection forming mold.
Background technology
The mould of thin-walled lid is ubiquitous equipment in the manufacturing of plastic casing.The mould of thin-walled lid traditional at present comprises counterdie and coordinates shaping patrix with counterdie, counterdie is provided with lower mode cavity, the discharging push pedal driven by power set is arranged with at the outer of lower mode cavity chamber, patrix is provided with a sprue, the defect that this mould exists is that mold integral build is larger, cause mfg. moulding die consumptive material larger, and the product of each injection mo(u)lding is less, efficiency very low comparatively speaking, the lid simultaneously manufactured is relatively thick, and heavier mass, the raw material manufactured a product also is wasted more.
Summary of the invention
For the deficiency that above-mentioned prior art exists, it is extremely convenient that the purpose of this utility model is to provide a kind of discharging, and mold integral is relatively light and handy, and disposablely produce multiple lid, production efficiency is high, the thin-walled lid injection forming mold of the advantage of lower cost of mfg. moulding die.
For realizing above-mentioned object, the utility model provides following technical scheme:
A kind of thin-walled lid injection forming mold, comprise counterdie and coordinate shaping patrix with counterdie, described counterdie is at least provided with the groove of more than six, lower mode cavity is provided with in groove, the end face that described patrix is relative with counterdie is provided with groove, is provided with the upper cavity coordinating with lower mode cavity and be formed into die cavity in groove; The edge of described lower mode cavity or lower mode cavity are provided with near the position at lower mode cavity edge the de-material air cleft be connected with external air-blowing device.
The utility model is set to further: when described forming cavity is square lid, and the both sides at the bottom of the chamber of upper cavity are respectively equipped with a sprue.
The utility model is set to further: when described forming cavity is circular lid, is laid with three sprues at the bottom of the chamber of upper cavity.
The utility model is set to further: when described forming cavity is the polygon lid being greater than four limits, is at least laid with three sprues at the bottom of the chamber of upper cavity.
The utility model is set to further: described patrix is provided with sprue, and sprue is communicated with the runner be located in patrix, and runner is communicated with corresponding sprue respectively.
By adopting technique scheme, the technique effect that the utility model reaches is: the setting of de-material air cleft, make discharging extremely convenient, decrease taking up room of the push pedal in traditional moulds, make mold integral relatively light and handy, and can multiple lower mode cavity be set on counterdie, disposablely produce multiple lid, production efficiency is high, the advantage of lower cost of mfg. moulding die, in addition sprue is arranged multiple, effectively raise the rapidity of material feeding simultaneously, can be injected in forming cavity by disposable for material very soon within the extremely short time, make the lighter weight of shaping product, and relatively traditional lid is very thin.

Detailed description of the invention
With reference to Fig. 1 ~ 5, a kind of thin-walled lid injection forming mold disclosed in the utility model, for the square lid of injection mo(u)lding, it comprises counterdie 10 and coordinates shaping patrix 11 with counterdie 10, counterdie 10 is at least provided with the groove of more than six, lower mode cavity 12 is provided with in groove, it is the structure of 8 lower mode cavities shown in figure, if the words of the entirety increasing of mould certainly, lower mode cavity can arrange more, the end face that described patrix 11 is relative with counterdie 10 is provided with groove, is provided with the upper cavity 13 coordinating with lower mode cavity 12 and be formed into die cavity in groove; In order to make the demoulding become convenient and swift, the edge of described lower mode cavity 12 or lower mode cavity 12 are provided with near the position at lower mode cavity 12 edge the de-material air cleft 14 be connected with external air-blowing device.Simultaneously in order to make the lighter weight of shaping product, and relatively traditional lid is very thin, and the both sides at the bottom of the chamber of upper cavity 13 are respectively equipped with a sprue 15.Two sprues can be relatively traditional mould, have the benefit that charging is fast, interior material cooling very fast of charging then forming cavity soon, the material entered into like this in forming cavity can be relatively less, and therefore quality can lighten.
With reference to Fig. 6 ~ 11, another kind of thin-walled lid injection forming mold disclosed in the utility model, for the circular lid of injection mo(u)lding, namely the difference that the mould of itself and square lid is maximum is be laid with three sprues 15 at the bottom of the chamber of upper cavity 13.
Certainly, when described forming cavity is the polygon lid being greater than four limits, at the bottom of the chamber of upper cavity, be at least laid with three sprues.
To sum up, described patrix 11 is provided with sprue 16, and sprue 16 is communicated with the runner 17 be located in patrix 11, and runner 17 is communicated with corresponding major ingredient mouth 15 respectively.
Above-described embodiment is only preferred embodiment of the present utility model, not limits protection domain of the present utility model according to this, therefore: all equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by within protection domain of the present utility model.
