Abstract
The utility model discloses a kind of mould with air discharge duct, comprise fixed half and moving half, the die cavity place of the mould of described fixed half and moving half composition offers the air discharge duct of the outer surface extending to fixed half and moving half, described air discharge duct end is provided with exhaust outlet, described exhaust outlet comprises anti-overflow portion and exhaust portion, described anti-overflow portion and exhaust portion are in hierarchic structure from top to bottom, described exhaust portion inside is provided with the steam vent communicated with mould inside, described anti-overflow minister degree is 5-10mm, degree of depth 0.05-0.07mm, the described exhaust portion degree of depth is 0.15-0.20mm, the exhaust outlet of described cover half/dynamic model is symmetrical set.The anti-overflow portion degree of depth of the utility model air discharge duct is more shallow, can prevent the material in mould from overflowing, the exhaust portion of intensification is then conducive to gas and discharges rapidly, and air discharge duct is symmetrical, more even when gas is discharged, decrease product and occur bad order and produce the probability of pore.
Description
Technical field
The utility model relates to injection molding field, more specifically relates to a kind of mould with air discharge duct.
Background technology
Often there will be in injection mould die trial is produced raw material lack of fill or injection moulding complete after sample easily produce the problem such as aberration, dark line, flow liner, surface indentation; discharge in time in the excessive gas hole that its chief reason is mould inside, and this excessive gas mainly come from die cavity exist moisture in air, plastics evaporate under injection temperature produce gas, plastics and produce gas, remover volatilization and the gas that produces.At present, for the problem producing excessive gas, current main method increases exhaust on mould, utilize air discharge duct to be discharged by gas, and air discharge duct arranges the unreasonable scavenging action that not only do not rise, can cause sample deformations or off size requirement on the contrary.At present, it is undesirable that air discharge duct final vacuum effect is set, sample still can be caused still to produce the problem such as aberration, dark line, flow liner, surface indentation, and unreasonable because air discharge duct is arranged in exhaust process, and material can overflow via air discharge duct, pollutes mould.Therefore, need a kind of good exhaust effect badly, and effectively can prevent the mould of logistics overflow in exhaust process.
Utility model content
The purpose of this utility model is the defect overcoming prior art, and provide a kind of mould with air discharge duct, this mould has good exhaust performance, can avoid being vented in injection moulding process bad, product surface unsightly, the situation of magnetic property instability.
The technical solution of the utility model is:
A kind of mould with air discharge duct, comprise fixed half and moving half, the die cavity place of the mould of described fixed half and moving half composition offers the air discharge duct of the outer surface extending to fixed half and moving half, described air discharge duct end is provided with exhaust outlet, described exhaust outlet comprises anti-overflow portion and exhaust portion, described anti-overflow portion and exhaust portion are in hierarchic structure from top to bottom, and described exhaust portion inside is provided with the steam vent communicated with mould inside.
Described anti-overflow minister degree is 5-10mm, degree of depth 0.05-0.07mm.
The described exhaust portion degree of depth is 0.15-0.20mm.
The exhaust outlet of described cover half/dynamic model is symmetrical set.
The beneficial effects of the utility model:
A kind of mould with air discharge duct that the utility model provides, the anti-overflow portion degree of depth of its air discharge duct is more shallow, can prevent the material in mould from overflowing, the exhaust portion of deepening then is conducive to gas and discharges rapidly, and air discharge duct is symmetrical, more even when gas is discharged, decrease product and occur bad order and produce the probability of pore.
Accompanying drawing explanation
The front view with the mould of air discharge duct that Fig. 1 provides for the utility model embodiment;
The vent groove configuration schematic diagram that Fig. 2 provides for the utility model embodiment;
In figure, 1-anti-overflow portion, 2-exhaust portion, 3-steam vent.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In injection moulding process, mould inside often produces excessive gas, it mainly comes from die cavity and there is air, in plastics, moisture evaporates and produces gas under injection temperature, plastics and the gas produced, the gas that remover volatilizees and produces, if gas is discharged not in time, raw material insufficient fill can be caused, demoulding is not enough, and final sample easily produces aberration, dark line, flow liner, the problems such as surface indentation, and current die venting poor effect, although be provided with exhaust outlet, but act on single, exhaust can only be used for as established exhaust outlet, and injection moulding process Raw is easily overflowed by exhaust outlet.
As Fig. 1, shown in Fig. 2, a kind of mould with air discharge duct, comprise fixed half and moving half, the die cavity place of the mould of described fixed half and moving half composition offers the air discharge duct of the outer surface extending to fixed half and moving half, described air discharge duct end is provided with exhaust outlet, the exhaust outlet of cover half/dynamic model is symmetrical set, be symmetrical arranged and be conducive to making the gas in whole die cavity quick, even discharge, and partial exhaust gas can not be caused not smooth and affect product appearance, exhaust outlet adopts from top to bottom, descending hierarchic structure, what be wherein positioned at top is anti-overflow portion 1, this Domain Volume is larger, can be used as buffering, material during to prevent from being vented in mould overflows, anti-overflow portion 1 length is 5-10mm, degree of depth 0.05-0.07mm, and the degree of depth of exhaust portion 2 is 0.15-0.20mm, the rapid discharge of gas is conducive to by deepening exhaust portion 2, and steam vent is arranged at exhaust portion inside, outward opening, product can be reduced by the setting of above-mentioned air discharge duct in injection moulding process to occur bad order and produce the probability of pore.
