Abstract
The utility model relates to an air exhausting mechanism which is applied to a mold. The air exhausting mechanism comprises an air-exhausting mold insert base and a plurality of air-exhausting mold inserts. A plurality of air-exhausting mold insert inserting grooves are formed in the air-exhausting mold insert base and distributed in a grid shape. The air-exhausting mold inserts are respectively tightly matched with the air-exhausting mold insert inserting grooves, and the air-exhausting mold inserts are of cylindrical shapes. Due to the facts that the air-exhausting mold inserts are distributed in a grid shape, and a gap is reserved between two adjacent air-exhausting mold inserts, air in a mold cavity is exhausted through air-exhausting gaps during product molding. The air exhausting mechanism simplifies the processing technology, simplified the assembly process and shortens processing time.
Description
[technical field]
The utility model relates to a kind of exhaust gear, particularly relates to a kind of exhaust gear be applied in mould.
[background technology]
Often have joint line on plastic cement products; joint line is melted material road or the formed fine rule of this melted material road above interflow part; not only two are advanced the glue point and can produce joint line; sometimes even one advance glue point and also can produce joint line because of the difference of product structure, the direction that joint line produces is all relevant with position, size and the plastic cement flowing temperature of advancing glue point.Yet, in the plastic mould manufacturing industry, requirement to outward appearance is strict especially, it is high minute surface that many product requirement appearance are arranged, must there is no joint line, when running into this outward appearance product, conventional design is that the Position Design exhaust at joint line enters son, the exhaust of using at present enters son and slaps together for sheet, and this sheet exhaust enters son following shortcoming:
1, processing technology is loaded down with trivial details;
2, dress mould personnel assemble difficulty;
3, long processing time.
In view of this, be necessary to provide in fact a kind of exhaust gear, this exhaust gear can solve the problem that the processing technology existed in prior art is loaded down with trivial details, assemble difficulty and long processing time.
[summary of the invention]
Therefore, the purpose of this utility model is to provide a kind of exhaust gear, and this exhaust gear can solve the problem that above-mentioned processing technology is loaded down with trivial details, assemble difficulty and long processing time.
In order to achieve the above object, exhaust gear of the present utility model, be applied in mould, and this exhaust gear comprises:
One exhaust enters sub-base, and this exhaust enters sub-base and is provided with some exhausts and enters sub-slot, and this exhaust enters sub-slot and is lattice-distribution; And
Some exhausts enter son, and this exhaust enters son and is tight with at respectively described exhaust and enters in sub-slot, and this exhaust enters son for column.
Preferably, to enter son be that partial volume is placed in exhaust and enters in sub-slot in described exhaust.
Preferably, described exhaust enters son and extends on direction laterally or longitudinally respectively and be arranged in during exhaust enters sub-slot.
Preferably, it is 0.03mm～0.04mm that two adjacent exhausts that extension is arranged on horizontal or longitudinal direction enter sub spacing range.
Preferably, described exhaust enters son for cuboid.
Preferably, described exhaust enters son, and to extend the limit that exhaust enters sub-slot be its height, and this exhaust enters sub height and is greater than length or width, and this exhaust enters sub length and equates with width.
Preferably, it is 5mm that described exhaust enters sub length, and width is 5mm.
Compared to prior art, exhaust gear of the present utility model, enter son and be lattice-distribution by exhaust is set, and two adjacent exhausts enter between son to be provided with certain gap, so that the gas in mold cavity emits by exhaust clearance when formed product, exhaust gear of the present utility model has been simplified processing technology, simple and easy assembling process and shortened process time.
[accompanying drawing explanation]
Fig. 1 illustrates the combination schematic diagram of the utility model exhaust gear.
Fig. 2 illustrates the decomposing schematic representation of the utility model exhaust gear.
[specific embodiment]
Refer to shown in Fig. 1 and Fig. 2 the combination schematic diagram that wherein Fig. 1 is the utility model exhaust gear, the decomposing schematic representation that Fig. 2 is the utility model exhaust gear.
Exhaust gear of the present utility model, it is applied in mould, and in the present embodiment, this exhaust gear comprises:
One exhaust enters sub-base 100, and this exhaust enters sub-base 100 and is provided with some exhausts and enters sub-slot 1001, and this exhaust enters sub-slot 1001 and is lattice-distribution; And
Some exhausts enter son 200, and this exhaust enters son 200 and is tight with at respectively described exhaust and enters in sub-slot 1001, in the present embodiment, refers to Fig. 2, and it is that partial volume is placed in exhaust and enters in sub-slot 1001 that this exhaust enters son 200, and this exhaust enters son 200 for column.
In the present embodiment, this exhaust enters son 200 and extends on direction laterally or longitudinally respectively and be arranged in during exhaust enters sub-slot 1001.
In the present embodiment, the spacing range that two adjacent exhausts enter son 200 is 0.03mm～0.04mm.
In the present embodiment, this exhaust enters son 200 for cuboid, refer to Fig. 2, exhaust enters son 200 and extend to that it is long on directions X, on Y-direction, extends to that it is wide, on the Z direction, extends to its height, the height that this exhaust enters son 200 is greater than length or width, this exhaust enters son 200 length and equates with width, and it is 5mm that this exhaust enters sub 200 length, and width is 5mm.
In the present embodiment, refer to Fig. 1, when the plastic cement products moulding, the plastic cement of melting is filled mold cavity hastily, drive the gas in die cavity, in order to prevent the bad situation of product, need in time the gas in mold cavity be discharged, because entering sub-slot 1001, exhaust is lattice-distribution, exhaust enters son 200 and is tight with at again exhaust and enters in sub-slot 1001, so entering son 200, exhaust also is lattice-distribution, in addition, two adjacent exhausts enter 200 of sons and are provided with certain gap, so direction regardless of joint line 300, gas in mold cavity can enter the son exhaust clearance of 200 by exhaust and emit.
Compared to prior art, exhaust gear of the present utility model, enter son and 200 be lattice-distribution by exhaust is set, and adjacent exhaust enters between son 200 to be provided with certain gap, so that the gas in mold cavity emits by exhaust clearance when formed product, exhaust gear of the present utility model has been simplified processing technology, simple and easy assembling process and shortened process time.
