Abstract

The utility model discloses an injection die which comprises an upper die and a lower die. The upper die is provided with a cavity group and a cold runner which is connected with the cavity group. The cavity group comprises two groups of cavities, the two groups of cavities are symmetrically arranged, the cold runner comprises two branch runners which are communicated with each other, each of the branch runners is communicated with one group of cavities, a feed inlet is arranged on the upper die, an ingate sleeve is disposed in the feed inlet, and the feed inlet is communicated with the cold runner through the ingate sleeve. By means of the injection die, purposes of saving raw materials and improving work efficiency are achieved.

Description

A kind of injection mold
Technical field
The utility model relates to a kind of mould, particularly a kind of injection mold.
Background technology
Current, in the injection mold industry, injection mold all has multi-point mould, large-scale characteristics usually, and the runner that therefore must prepare complicacy is shunted, so that the even charging of each die cavity.
Thermosetting plastics; Like phenolic resins, epoxy resin etc., its be heated reach uniform temperature after molecular structure can change into network structure, even behind the curing molding again the heating; Can not make it once more softening, this material has thermal insulation, wearability, insulating properties and characteristics such as insoluble.When using current injection mold that the heat fixing character plastics are carried out injection moulding; In the cooling procedure of product, raw material in the runner and the raw material in the die cavity can cool off and be connected as a single entity simultaneously, will have one section bigger cold burden handle on the product after the moulding; Need the cold burden handle be pruned separately; Not only lose time, reduce operating efficiency, but also wasted raw material.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of injection mold, economize in raw materials to reach, and the purpose that can increase work efficiency.
For achieving the above object, the technical scheme of the utility model is following:
A kind of injection mold comprises upper die and lower die, and said patrix is provided with die cavity crowd and the cold runner that is connected with said die cavity faciation; Said die cavity crowd comprises two groups of symmetrically arranged die cavities; Said cold runner comprises two runners that communicate, and every runner is connected with one group of die cavity, and patrix is provided with charging aperture; Be provided with a sprue bush in the charging aperture, be connected with said cold runner through said sprue bush.
Preferably, also be provided with thermal insulation board on the said cope match-plate pattern.
Preferably, said runner links to each other with said die cavity through the mouth of a river that is flat bellmouth orifice shape.
Through technique scheme, a kind of injection mold that the utility model provides is to be provided with the cold runner that is communicated with the die cavity faciation, and this cold runner comprises two runners that communicate; Every runner is connected with one group of die cavity, and material gets into from charging aperture, in cold runner, is in molten condition; During die sinking, the molten state material in product and the runner is separated, and can directly take out product; Need not to prune the cold burden handle, simultaneously, the material in the runner can also continue to use; Realize producing continuously, not only improved production efficiency, and practiced thrift raw material.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below.
Fig. 1 is the structural representation of the disclosed a kind of injection mold of the utility model embodiment.
The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.
The utility model provides a kind of injection mold, and referring to shown in Figure 1, it comprises patrix 1 and counterdie 2; Patrix 1 is provided with die cavity crowd and the cold runner 3 corresponding with the die cavity faciation, and the die cavity crowd comprises two groups of symmetrically arranged die cavities 4, and cold runner comprises two runners that communicate 5; Every runner is connected with one group of die cavity through the mouth of a river that is flat bellmouth orifice shape; Patrix is provided with charging aperture 6, is provided with a sprue bush 7 in the charging aperture, is connected with said cold runner 3 through sprue bush 7.
Also be provided with thermal insulation board 8 on the cope match-plate pattern, the low temperature part 81 of patrix is separated with high-temperature part 82 mutually.In the production process, owing to have certain temperature in the runner, the material in it can remain molten condition; During die sinking, the molten state material in product and the runner is separated, and can directly take out product; Need not to prune the cold burden handle, simultaneously, the material in the runner can also continue to use; Realize producing continuously, not only improved production efficiency, and practiced thrift raw material.
