Abstract
The utility model discloses a die mould exhaust mechanism, including the back template, be equipped with back mould benevolence in the back template, be equipped with in the back mould benevolence and be lambdoid air discharge duct, the air discharge duct lower extreme be equipped with gas vent, upper end that the die cavity that is equipped with in a plurality of and the back mould benevolence is connected be connected with set up in back template and be wavy exhaustion plate, the utility model has the advantages of simple structure, it is more smoothly more a large amount of to exhaust, makes the interior air of mould cavity obtain abundant release, in the mould of discharging completely, makes the product not have the trachoma pore -free.
Description
Technical field
This utility model relates to technical field of mold, particularly relates to a kind of compression mod exhaust gear.
Background technology
Die casting is a kind of instrument producing plasthetics；Also the instrument of plasthetics complete structure and accurate dimension it is to confer to.Die casting is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model constitutes running gate system and die cavity with cover half Guan Bi, and during die sinking, dynamic model separates with cover half to take out plastic；Traditional aerofluxus directly open shallow air discharge duct air be discharged to framed outside, capacity is not enough, still has partial air and fails aerofluxus, makes to be formed on product pore and trachoma.
Utility model content
The purpose of this utility model is to provide a kind of compression mod exhaust gear for the deficiencies in the prior art, this compression mod exhaust gear simple in construction, the more smooth and easy greater amount of aerofluxus, in making cavity body of mould, air is sufficiently discharged, it is completely exhausted out in mould, makes product without trachoma pore-free.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions.
A kind of compression mod exhaust gear, include rear pattern plate, rear pattern plate is provided with rear cavity, and rear cavity is provided with in lambdoid air discharge duct, air discharge duct lower end is provided with air vent that several die cavitys being provided with rear cavity are connected, upper end connect have that be arranged on rear pattern plate and in wavy exhaustion plate.
Wherein, the other end that described rear pattern plate is positioned at exhaustion plate corresponding is equiped with spreader.
Wherein, described spreader is provided with that be connected with rear cavity and in lambdoid runner.
Wherein, described runner is provided with several runner mouths being connected with described die cavity.
The beneficial effects of the utility model are: a kind of compression mod exhaust gear described in the utility model, include rear pattern plate, rear pattern plate is provided with rear cavity, rear cavity is provided with in lambdoid air discharge duct, air discharge duct lower end is provided with air vent that several die cavitys being provided with rear cavity are connected, upper end connect have that be arranged on rear pattern plate and in wavy exhaustion plate, this utility model has simple in construction, the more smooth and easy greater amount of aerofluxus, in making cavity body of mould, air is sufficiently discharged, it is completely exhausted out in mould, makes product without the imperforate advantage of trachoma.
Accompanying drawing explanation
Below with accompanying drawing, this utility model is further detailed, but the embodiment in accompanying drawing is not constituted any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
Include in FIG:
1 rear pattern plate
11 rear cavities
12 die cavitys
2 air discharge ducts
21 air vents
22 exhaustion plates
3 spreaders
31 runners
32 runner mouths.
Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is illustrated.
As shown in Figure 1, a kind of compression mod exhaust gear, include rear pattern plate 1, rear pattern plate 1 is provided with rear cavity 11, rear cavity 11 is provided with in lambdoid air discharge duct 2, air discharge duct 2 lower end is provided with air vent 21 that several die cavitys 12 being provided with rear cavity 11 are connected, upper end connect have that be arranged on rear pattern plate 1 and in wavy exhaustion plate 22.
Further, described rear pattern plate 1 is positioned at the other end of exhaustion plate 22 correspondence and is equiped with spreader 3.
Further, described spreader 3 is provided with that be connected with rear cavity 11 and in lambdoid runner 31.
Further, described runner 31 is provided with several runner mouths 32 being connected with described die cavity 12.
Need to further explain, this utility model uses wavy exhaustion plate 22 to connect the design of air discharge duct 2, air discharge duct 2 aerofluxus comparing the degree of depth can be opened, and use the threshold values control material of exhaustion plate 22 not spill over, the more smooth and easy greater amount of aerofluxus, in making cavity body of mould, air is sufficiently discharged, and is completely exhausted out in mould, makes product without trachoma pore-free.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the most all will change, this specification content should not be construed as restriction of the present utility model.
