Abstract
The utility model discloses an air exhausting device of an injection mould. The air exhausting device comprises a vacuumizing box, a vacuum pipeline, an air inlet pipeline, a fixing device and an air absorption opening, wherein the vacuumizing box is connected with the air absorption opening through the vacuum pipeline; a fixing device is fixed on the periphery of the upper end of the air absorption opening; the air inlet pipeline is arranged above the fixing device; the air inlet pipeline and the vacuum pipeline are in sealed and penetrated connection. The air exhausting device of the injection mould disclosed by the utility model can be fixed on the surface of the mould through a thread through hole and the air absorption opening stretches into the mould; a high temperature in a mould cavity is reduced through the vacuumizing box; meanwhile, injection pressure in the mould is reduced, the energy consumption of the machine is reduced, and the defects of flow lines, fusion lines, scotch batches and the like on the surface of a product are also improved.
Description
Technical field
The utility model is specifically related to a kind of exhaust apparatus of injection mold, belongs to mould parts and makes the field.
Background technology
Mould is a kind of instrument of producing plastic products, during injection moulding, clamping mould is on injection machine, molten plastic is injected in shaping mold cavity, and in the chamber cooling and shaping, then upper and lower mould separately, ejects goods via ejection system and leaves mould from die cavity, last mould closure again carries out injection moulding next time, and whole injection moulding process loops; Usually because lack of fill, compressed air are hot, the problems such as very high internal stress, surface streamline, fusion line, focal spot can appear to existing injection mold in the product of completing at last, have a strong impact on aesthetics and the reliability of product.
Summary of the invention
The utility model is for the deficiencies in the prior art, proposed a kind of timely cooling, easily controlled the exhaust apparatus of the injection mold of temperature in mould.
The technical solution of the utility model is achieved like this: a kind of exhaust apparatus of injection mold comprises vacuumizing case, vacuum pipe, gas feeding pipe, fixture and absorption of air mouth; The described case that vacuumizes connects the absorption of air mouth by vacuum pipe; Periphery, described absorption of air mouth upper end is fixed with fixture; Described fixture top is provided with gas feeding pipe; Described gas feeding pipe is connected with vacuum pipe and passes through mutually connection.
As preferably, described gas feeding pipe is more than two or two.
As preferably, the porch of described gas feeding pipe is provided with into the gas mesh.
As preferably, described fixture is round pie, is provided with tapped through hole on described fixture.
As preferably, described absorption of air mouth is funnel-form.
Compared with prior art, the exhaust apparatus of injection mold of the present utility model can be fixed on die surface by tapped through hole, the absorption of air mouth stretches in mould, by vacuumizing case, the high temperature in mold cavity is lowered, simultaneously the injection pressure in mould is reduced, reduce the energy dissipating consumption of machine, also can improve the defectives such as product surface streamline, fusion line, focal spot.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Coding in figure is respectively: 1 for vacuumizing case; 2 is vacuum pipe; 3 is the absorption of air mouth; 4 is tapped through hole; 5 is fixture; 6 is gas feeding pipe; 7 for entering the gas mesh.
The specific embodiment
As shown in Figure 1, the exhaust apparatus of this injection mold comprises vacuumizing case 1, vacuum pipe 2, gas feeding pipe 6, fixture 5 and absorption of air mouth 3; The described case 1 that vacuumizes connects absorption of air mouth 3 by vacuum pipe 2; Described absorption of air mouth 3 peripheries, upper end are fixed with fixture 5; Described fixture 5 tops are provided with gas feeding pipe 6; Described gas feeding pipe 6 is connected sealing and is passed through mutually connection with vacuum pipe.
It should be noted that described gas feeding pipe 6 is more than two or two.
Porch that it should be noted that described gas feeding pipe 6 is provided with into gas mesh 7.
It should be noted that described fixture 5 is round pie, is provided with tapped through hole 4 on described fixture 5.
It should be noted that described absorption of air mouth 3 is funnel-form.
The exhaust apparatus of injection mold of the present utility model can be fixed on die surface by tapped through hole, the absorption of air mouth stretches in mould, by vacuumizing case, the high temperature in mold cavity is lowered, simultaneously the injection pressure in mould is reduced, reduce the energy dissipating consumption of machine, also can improve the defectives such as product surface streamline, fusion line, focal spot.
