Specific embodiment
The exhaust apparatus of inventive die is suitable for producing various molds.
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the preferred reality of the exhaust apparatus of the present invention is described in detail mold
Apply example.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the present invention provides a kind of exhaust apparatus 8 of mold, packet
Include air drain 8.1, exhaust clearance 8.2 and exhaust passage 8.3, the exhaust clearance 8.2 and 8.1 connection of air drain, the air drain
8.1 with 8.3 connection of exhaust passage, which is characterized in that further include vacuum evacuation device 8.4, the vacuum evacuation device 8.4 and institute
State exhaust passage 8.3 connection, the exhaust clearance 8.2 divide for two or more, each exhaust clearance 8.2
Size is set according to the difference of the 8.2 place die location of exhaust clearance, and the vacuum evacuation device 8.4 connects gas source 9.
Due to having gas originally in mold cavity, when liquid material to be injected into the near closed hollow ring of mold, or it is living
When ejector half cavity volume becomes smaller, the gas in mold cavity will be discharged to the air flue 8.1 by the exhaust clearance 8.2, then pass through
Mold is discharged in the exhaust passage 8.3, and the vacuum evacuation device 8.4 is connect with the exhaust passage 8.3, when the gas in mold
When cannot be discharged in time, start the vacuum evacuation device 8.4, accelerates the gas for making type intracavitary discharge.
In other embodiments, the size of the exhaust clearance 8.2 of the exhaust apparatus of inventive die is from from mold
Feed inlet most proximal end successively changes to the feed inlet distalmost end from mold.
In the present embodiment, the size of the exhaust clearance 8.2 of the exhaust apparatus of inventive die from from mold into
Material mouth most proximal end is sequentially increased to the feed inlet distalmost end from mold, since liquid material enters closed type chamber from feed inlet,
Raw material can catch up with the past feed inlet distal end from mold of gas, so it is more to will lead to gas remoter from feed inlet, so the row
The size in gas gap 8.2 is sequentially increased from the feed inlet most proximal end from mold to the feed inlet distalmost end from mold, facilitates gas
Discharge in time.
In the present embodiment, the size of the exhaust clearance 8.2 of the exhaust apparatus of inventive die forms most from mold
Easy position successively changes to the position that mold molding is most difficult to.
In the present embodiment, the size of the exhaust clearance 8.2 of the exhaust apparatus of inventive die forms most from mold
Easy position is sequentially increased to the position that mold molding is most difficult to, and when raw material enters type chamber, mold forms the position being easiest to
Product is easy the volume that molding occupies type chamber, can catch up with gas toward the position that mold molding is most difficult to, so the exhaust clearance 8.2
Size be sequentially increased from the mold position that is easiest to of molding to the position that mold molding is most difficult to, facilitate gas to be discharged in time.
In the present embodiment, the size of the exhaust clearance 8.2 of the exhaust apparatus of inventive die is L, L=
0.025mm。
In the present embodiment, the air drain 8.1 of the exhaust apparatus of inventive die surrounds mold cavity circumferential distribution.
In the present embodiment, the air drain 8.1 of the exhaust apparatus of inventive die is one, the exhaust passage 8.3
It is two or two or more, described 8.3 one end of exhaust passage and 8.1 connection of air drain, other end and atmosphere join
It is logical.
In other embodiments, the size of the exhaust clearance 8.2 of the exhaust apparatus of inventive die is L, 0.005mm
≤L≤0.05mm。
Compared with prior art, have the advantages that can be quickly by type for the exhaust apparatus of inventive die
Intracavitary gas discharge, does not influence the mobility of liquid material, avoids influencing formed product, to improve the yield of product.
Above disclosed is only presently preferred embodiments of the present invention, cannot limit the right of the present invention with this certainly
Range, therefore according to equivalent variations made by scope of the present invention patent, it is still within the scope of the present invention.
