Description
Technical field
The invention belongs to injection mold technology more particularly to a kind of injection molds.
Background technique
Existing industrial products generally use injection molding process, and injection molding process it is most important be mold knot
Structure when molding injection heats the plastics of shape, can usually bring air into, heat the plastics of shape in the production process of industrial products
Air can be squeezed in the intracavitary flowing of the type of mold, air cannot be such as effectively discharged out, will result in trapped gas phenomenon, although existing
Having in technology can be exhausted using air gap is held, but this exhaust mode is inefficient, be produced faster in production cooling velocity
It is vented not prompt enough when product, will affect the quality of injecting products.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of injection mold, it is intended to improve injection mold discharge air
When rate, thus improve injection mold production product quality.
In order to solve the above technical problems, the invention is realized in this way, a kind of injection mold, comprising: the first mode, second
Mode, third mode, mold insert and exhaust apparatus, first mode, second mode and the third mode are set gradually,
It is offered on second mode and inlays channel, offer exhaust passage on the third mode, the exhaust passage and described
Channel to be inlayed to be correspondingly arranged, the exhaust passage is connected with the exhaust apparatus, and the mold insert is embedded to be inlayed in channel described,
There is the interval passed through for air, when first mode, described second between the mold insert and the inner wall for inlaying channel
When mode and third mode injection molding molding, shape forming cavity between first mode and second mode is described to inlay
Channel is connected to the type chamber and the exhaust passage, the molten plastic that the mold insert stops the type intracavitary enter the exhaust
In channel, the exhaust apparatus vacuumizes to extract the intracavitary air of the type out the exhaust passage.
Further, the land area for extending perpendicularly to second mode for inlaying channel, the mold insert
Bottom surface is concordant with the land area of second mode.
Further, the exhaust passage includes interconnected interface channel and collection channel, and the interface channel connects
Channel is inlayed described in logical, the collection channel connects the exhaust apparatus.
Further, the extending direction of the interface channel is identical as the corresponding extending direction for inlaying channel, institute
State the extending direction for extending perpendicularly to the interface channel of collection channel.
Further, the cross-sectional area of the interface channel is greater than the cross-sectional area for inlaying channel.
Compared with prior art, beneficial effect is injection mold in the present invention:
When the first mode, the second mode and third mode carry out mould assembling action, shape between the first mode and the second mode
Forming cavity, the second mode and the contact of third mode, it is intracavitary to form product that molten plastic enters type, in this process, row
Device of air vacuumizes exhaust passage, thus make exhaust passage and inlay channel formation negative pressure, under the action of negative pressure,
The intracavitary air of type can faster and more fully pass through from mold insert and the interval for inlaying between channel and is vented from exhaust passage
Device extracts mold out, and injection mold of the invention can be improved rate when injection mold discharge air, can efficiently eliminate
The trapped gas phenomenon of injection mold, to improve the quality of the product of injection mold production.

Embodiment:
In the present embodiment, as shown in Figure 1-3, injection mold include: the first mode 1, the second mode 2, third mode 3,
Mold insert 4 and exhaust apparatus (not shown), the first mode 1, the second mode 2 and third mode 3 set gradually, open on the second mode 2
Equipped with channel 21 is inlayed, exhaust passage 31 is offered on third mode 3, exhaust passage 31 and inlay channel 21 and be correspondingly arranged, arrange
Gas channel 31 is connected with exhaust apparatus, and mold insert 4, which is embedded, to be inlayed in channel 21, has between mold insert 4 and the inner wall for inlaying channel 21
There is the interval passed through for air, when the first mode 1, the second mode 2 and third mode 3, which are molded, to be molded, the first mode 1 and second
Shape forming cavity between mode 2, inlays 21 communicate-type chamber of channel and exhaust passage 31, the intracavitary molten plastic of 4 barrier type of mold insert into
Enter into exhaust passage 31, exhaust apparatus vacuumizes to extract the intracavitary air of type out exhaust passage 31.
When the first mode 1, the second mode 2 and third mode 3 carry out mould assembling action, the first mode 1 and the second mode 2 it
Between shape forming cavity, the second mode 2 and third mode 3 contact, and it is intracavitary to form product 001 that molten plastic enters type, at this
In the process, exhaust apparatus vacuumizes exhaust passage 31, thus make exhaust passage 31 and inlay the formation of channel 21 negative pressure,
Under the action of negative pressure, the intracavitary air of type faster and more fully from mold insert 4 and can inlay the interval between channel 21 and pass through
And mold is extracted out from exhaust passage 31 by exhaust apparatus, when injection mold of the invention can be improved injection mold discharge air
Rate, can efficiently eliminate the trapped gas phenomenon of injection mold, to improve the quality of the product 001 of injection mold production.
Specifically, in the present embodiment, inlaying the land area for extending perpendicularly to the second mode 2 in channel 21, mold insert 4
Bottom surface it is concordant with the land area of the second mode 2, to make 001 smooth surface of product to be formed.In other embodiments, it inlays
The extending direction in channel 21 can angular range between the land area of the second mode 2 between 60 ° -90 °, such as: 60 °,
61°、62°、63°、64°、65°、66°、67°、68°、69°、70°、71°、72°、73°、74°、75°、76°、77°、78°、79°、
80 °, 81 °, 82 °, 83 °, 84 °, 85 °, 86 °, 87 °, 88 ° or 89 ° etc..
Exhaust passage 31 includes interconnected interface channel 311 and collection channel 312, and the connection of interface channel 311 is inlayed
Channel 21, collection channel 312 connect exhaust apparatus, the extending direction of interface channel 311 and the corresponding extension for inlaying channel 21
Direction is identical, the extending direction for extending perpendicularly to interface channel 311 of collection channel 312.Specifically, in the present embodiment
In, it is provided with one on the second mode 2 and inlays channel 21, it is corresponding, an interface channel 311 is provided on third mode 3
With collection channel 312, it may be assumed that there is the intracavitary air of type a channel to lead to exhaust apparatus；In other embodiments, in order to adapt to
Two, three, four, five, six etc. can be set on the second mode 2 and inlay channel 21, often for the shape and size of type chamber
A inlay can be respectively provided with mold insert 4 in channel 21, corresponding, and two, three, four, five, six are arranged on third mode 3
A equal interface channel 311 and collection channel 312, it may be assumed that the intracavitary air of type have corresponding two, three, four, five,
Exhaust apparatus is led in six channels, further improves the speed that air is discharged from type chamber；In other embodiments, it inlays logical
Road 21 and interface channel 311 can be respectively provided with two, three, four, five, six etc., but the quantity of collection channel 312 is less than
The quantity of interface channel 311 a, it may be assumed that collection channel 312 can be simultaneously with one, two, three, four or five etc. company
It connects road 311 to be connected, multiple air inlayed in channel 21 can be made to lead to row by lesser amount of collection channel 312 in this way
Device of air, therefore the space of mold has been saved, reduce the manufacturing cost of mold.
The cross-sectional area of interface channel 311 is greater than the cross-sectional area for inlaying channel 21.In the present embodiment, connection is logical
