Abstract
The utility model patent discloses a kind of mould with gas-assisted molding mechanism, comprises mould bases and the die mating with described mould bases, and shaped article is arranged on described die top; Also comprise and run through the gas-assisted molding mechanism that is arranged on described mould bases and described die inside, the gas in described gas-assisted molding mechanism arrives shaped article from described mould bases bottom through described die.Mould with gas-assisted molding mechanism provided by the utility model, the gas in gas-assisted molding mechanism arrives shaped article from mould bases bottom through die, to shaped article is local, blows.The uniformity that has guaranteed product wall thickness, after moulding, product can not shrink, and has improved product appearance quality, has effectively shortened molding cycle, has improved production efficiency; Because product wall thickness is even, reduced unnecessary waste of raw materials, saved the cost of raw materials for production.
Description
Technical field
The utility model relates to a kind of mould with gas-assisted molding mechanism.
Background technology
The auxiliary technology of gas can be applied in nearly all plastic part fields such as household electrical appliances, automobile, furniture, articles for daily use, office appliances.Some injecting products is due to the needs of function, and cross-sectional area is larger, if injection moulding in a general manner, the local meat of shaped article is thick, after moulding, can shrink, and molding cycle is long, and production efficiency is low, and presentation quality is poor.
Utility model content
In order to prevent shrinking after formed product, improve product appearance quality, shorten molding cycle, to enhance productivity, the utility model provides a kind of mould with gas-assisted molding mechanism.
In order to solve above technical problem, the technical solution of the utility model is: a kind of mould with gas-assisted molding mechanism, comprise mould bases and the die mating with described mould bases, and shaped article is arranged on described die top; Also comprise and run through the gas-assisted molding mechanism that is arranged on described mould bases and described die inside, the gas in described gas-assisted molding mechanism arrives shaped article from described mould bases bottom through described die.
As preferably, described gas-assisted molding mechanism comprises the air admission hole being connected with blowning installation that is arranged on described mould bases bottom, and be arranged on described die inside with holes-air inlet needle, between described die and air inlet needle, be provided with space; Described air admission hole is communicated with by inlet channel with described air inlet needle.
As preferably, the upper right corner of described air inlet needle, the hole in described air inlet needle-be arranged on.
As preferably, between described die and described air inlet needle, be provided with the first sealing ring.
As preferably, inlet channel and described air inlet needle junction are provided with the second sealing ring.
Mould with gas-assisted molding mechanism provided by the utility model, the gas in described gas-assisted molding mechanism arrives shaped article from described mould bases bottom through described die, to shaped article is local, blows.When gas flows in fused materials, by displacement fused materials, empty heavy wall cross section, gas flows to low pressure and the high-temperature area of die cavity along the minimum direction of resistance, thereby guarantee the uniformity of product wall thickness, after moulding, product can not shrink, improve product appearance quality, effectively shortened molding cycle, improved production efficiency; Because product wall thickness is even, reduced unnecessary waste of raw materials, saved the cost of raw materials for production.
Accompanying drawing explanation
Fig. 1 is the structural representation of the mould with gas-assisted molding mechanism provided by the utility model.
Shown in figure: 1, mould bases, 2, die, 3, shaped article, 4, air admission hole, 5, air inlet needle, 5-1, hole, 6, inlet channel, the 7, first sealing ring, the 8, second sealing ring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: please refer to Fig. 1, a kind of mould with gas-assisted molding mechanism, comprises mould bases 1 and the die 2 mating with described mould bases 1, and shaped article 3 is arranged on described die 2 tops; Also comprise and run through the gas-assisted molding mechanism that is arranged on described mould bases 1 and described die 2 inside, the gas in described gas-assisted molding mechanism arrives shaped article 3 from described mould bases 1 bottom through described die 2.
Described gas-assisted molding mechanism comprises the air admission hole being connected with blowning installation 4 that is arranged on described mould bases 1 bottom, and the air inlet needle 5 that is arranged on the 5-1 with holes of described die 2 inside, between described die 2 and air inlet needle 5, is provided with space; Described air admission hole 4 is communicated with by inlet channel 6 with described air inlet needle 5.The gas that blowning installation blows out reaches shaped article 3 places by the space between the hole 5-1 in air admission hole 4, inlet channel 6, air inlet needle 5, air inlet needle 5 and described die 2 and described air inlet needle 5 successively.
Hole 5-1 in described air inlet needle 5 is arranged on the upper right corner of described air inlet needle 5, nearer apart from the place that shaped article meat is thick, to shaped article air blowing better effects if.
Between described die 2 and described air inlet needle 5, be provided with the first sealing ring 7, described the first sealing ring 7 has the effect that prevents that gas from leaking from die 2 bottoms.
Described inlet channel 6 is provided with the second sealing ring 8 with described air inlet needle 5 junctions.Described the second sealing ring 8 has the effect that prevents that gas from leaking from described inlet channel 6 and described air inlet needle 5 junctions.
Blowning installation gas used can be the nitrogen of high pressure compressed.Blowning installation can adopt existing device, nozzle as auxiliary in self-closed type gas or air tube etc.
Mould with gas-assisted molding mechanism provided by the utility model, can be applied to the product that varied in thickness is large, as the gas-assisted forming mold of the large product of varied in thickness.
Mould operation process with gas-assisted molding mechanism provided by the utility model: open air admission hole 4, utilize blowning installation to the interior air blowing of air admission hole 4, gas reaches shaped article 3 places by the space between the hole 5-1 in air admission hole 4, air inlet needle 5 and described die 2 and described air inlet needle 5, to shaped article 3 is local, blows.When gas flows in fused materials, by displacement fused materials, empty heavy wall cross section, gas flows to low pressure and the high-temperature area of die cavity along the minimum direction of resistance, thereby guarantees the uniformity of product wall thickness.
Provided by the utility modelly with product after the mould molding of gas-assisted molding mechanism, can not shrink, improve product appearance quality, effectively shorten molding cycle, improve production efficiency; Because product wall thickness is even, reduced unnecessary waste of raw materials, saved the cost of raw materials for production.
Those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these change and modification.
