Abstract

The utility model discloses an injection mold air discharge duct, it includes, and the structure is the same, the whole air discharge duct in the border of variation in size and the big air discharge duct in outer end, and the whole air discharge duct in border links together with the big air discharge duct in outer end and constitutes a whole, and the width ratio of border whole air discharge duct and the big air discharge duct in outer end is 1: 3, the degree of depth of the whole air discharge duct in border is 0.01 -0.02mm, and the degree of depth of the big air discharge duct in outer end is 0.2 -0.5mm. Optimized exhaust structure, whole exhaust, the gaseous smooth of in -process production that be favorable to moulding plastics is gone out from the all directions drainage, has guaranteed product quality, simultaneously, makes the injection moulding state space improve greatly, and the increasing of controllability scope improves the yields.

Description

Injection mold air discharge duct
Technical field
The utility model belongs to injection mold, is specifically related to a kind of injection mold air discharge duct.
Background technology
In the process of plastic pellet melting filling injection die cavity, in die cavity except original air, the gas that the low molecular weight volatile gas that the steam also having the moisture that plastics contain to evaporate under injection temperature, the decomposition of plastics hot-spot produce, plastic additive volatilization (or chemical reaction) produce and thermosetting plastics are cross-linked the gas of sclerosis release.If these gases can not be discharged die cavity, the quality of product molding will be affected.Conventional vent grooves is symmetrical structure, can not be discharged by these gases well.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the purpose of this utility model is, provides a kind of injection mold air discharge duct, optimizing exhaustion structure.
The injection mold air discharge duct that the utility model provides, it comprises the structure overall air discharge duct in border that is identical, that vary in size and the large air discharge duct in outer end, the overall air discharge duct in border and the large air discharge duct in outer end link together formation entirety, the width of the overall air discharge duct in border and the large air discharge duct in outer end is than being 1:3, the degree of depth of the overall air discharge duct in border is 0.01-0.02mm, and the degree of depth of the large air discharge duct in outer end is 0.2-0.5mm.
The injection mold air discharge duct that the utility model provides, its beneficial effect is, optimize exhaust structure, overall exhaust, the smooth drainage from all quarter of the gas being conducive to producing in injection moulding process is gone out, and ensure that product quality, simultaneously, injection molding process space is improved greatly, and controllability scope strengthens, and improves yields.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
Mark in figure:
1. the overall air discharge duct in border; 2. the large air discharge duct in outer end.
Detailed description of the invention
With reference to the accompanying drawings, in conjunction with an embodiment, the injection mold air discharge duct that the utility model provides is described in detail.
Embodiment
With reference to Fig. 1, the injection mold air discharge duct of the present embodiment, it comprises the structure overall air discharge duct 1 in border that is identical, that vary in size and the large air discharge duct 2 in outer end, the overall air discharge duct 1 in border and the large air discharge duct 2 in outer end link together formation entirety, the width of the overall air discharge duct 1 in border and the large air discharge duct 2 in outer end is than being 1:3, the degree of depth of the overall air discharge duct 1 in border is 0.01mm, and the degree of depth of the large air discharge duct 2 in outer end is 0.3mm.
When injection moulding is produced, residual gas is discharged to the large air discharge duct 2 in outer end by the overall air discharge duct 1 in border, and the enough gas of the degree of depth of the large air discharge duct in outer end 2 is discharged smoothly, is conducive to injection moulding and produces and ensure product quality.
