Description
Technical field
The utility model relates to a kind of for processing the technical field of mold of thin-wall product, in particular to a kind of for processing
The novel die structure of thin-wall product.
Background technique
In the production of injecting products, with thin-walled feature product manufacture difficulty it is higher, some thin-wall products it is thin
Wall wall thickness is even less than 0.5mm.Since the wall thickness of product is relatively thin, when injection molding, there are the difficulties of filling, that is, allow to overcome injection molding
When existing filling it is difficult, the case where product produced also inevitably will appear batch peak flash.In existing production, usually
It is difficult come filling existing when overcoming injection molding by using the Shooting Technique of high-voltage high-speed, and mentioned by increasing using heating bar
The mobility of high plastic cement；But this mode can cause biggish locked mode pressure to the die joint of mold, be easy so that mold
It is damaged at sealing mouth, in turn results in produced product and the case where criticizing peak flash occur.As it can be seen that existing production method is not only
The unstable quality for the product for needing higher production cost, and being produced, bad product rate is higher, and additionally there are injection moldings
Period longer problem.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of for processing the novel of thin-wall product
Mould structure.
To achieve the above object, the utility model adopts the following technical solutions: it is a kind of for processing the new of thin-wall product
Pattern lamps structure is applied to injection mold, and the walled thickness range for the thin-wall product processed is 0.1mm~1mm,
Exhaust structure is equipped at the male model die joint of injection mold, the exhaust structure includes first exhaust runner, the
Two grate flow channels, several first row air drains, several second row air drains, the first row air drain are set respectively with the second row air drain
In the two sides of the first exhaust runner, the type chamber of one end connection male model of the first row air drain, the first row air drain
The other end connection first exhaust runner, one end connection first exhaust runner of the second row air drain, described second
The other end of air discharge duct is connected to the second exhaust runner；
Several pressure-bearing adjustment blocks for being used to adjust injection mold seal degree are provided at the master mold die joint of injection mold,
At the master mold die joint of the pressure-bearing adjustment block setting injection mold；
When molding, the pressure-bearing adjustment block not with the first exhaust runner, the second exhaust runner, the first row
Air drain, the second row air drain are in contact.
It is further described, the width range of the first row air drain is 0.02mm~0.05mm.
It is further described, the quantity of the second row air drain is less than the quantity of the first row air drain.
The utility model has the beneficial effects that: the utility model is by the way that certain exhaust structure is arranged in male model, so that
Air in type chamber can be arranged quickly, and then solve the problems, such as that existing filling is difficult when injection molding, and plastic cement is filled more in a mold
Quickly, more smooth；Meanwhile pressure-bearing adjustment block is set in master mold, injection mold is adjusted by changing the thickness of pressure-bearing adjustment block
Seal degree, and cooperate the exhaust structure on male model, keep die venting convenient, effectively acts as preventing product from generating batch peak flash
Effect, and the locked mode pressure at die joint can be shared, keep mold more durable.The utility model is without processing
High Shooting Technique carries out high pressure, is molded at high speed, the matter for the product for not only reducing production cost, and being produced
Amount is stablized, and yields is high, moreover it is possible to save the time that die adjustment matches mould, be effectively shortened injection cycle.

Specific embodiment
It is right to attached drawing 3 below in conjunction with attached drawing 1 to keep the purpose of this utility model, technical solution and advantage clearer
The utility model is described in further detail.
It is a kind of to be applied to injection mold for processing the novel die structure of thin-wall product, the thin-wall product processed
Walled thickness range is 0.1mm~1mm,
As shown in attached drawing 1 and attached drawing 3, exhaust structure 10, exhaust structure 10 are equipped at the male model die joint 30 of injection mold
It include first exhaust runner 11, second exhaust runner 12, several first row air drains 13, several second row air drains 14, first row
Air drain 13 and second row air drain 14 are respectively arranged on the two sides of first exhaust runner 11, one end connection male model of first row air drain 13
Type chamber 40, the other end of first row air drain 13 are connected to first exhaust runner 11, and one end of second row air drain 14 is connected to first exhaust
The other end of runner 11, second row air drain 14 is connected to second exhaust runner 12；
As shown in Fig. 2, it is provided at the master mold die joint 50 of injection mold several for adjusting injection mold sealing journey
The pressure-bearing adjustment block 20 of degree, pressure-bearing adjustment block 20 are arranged at the master mold die joint 50 of injection mold；When molding, pressure-bearing adjustment block 20
It is not in contact with first exhaust runner 11, second exhaust runner 12, first row air drain 13, second row air drain 14.Such as 2 institute of attached drawing
Show, the shape of pressure-bearing adjustment block 20 is not specifically limited, and pressure-bearing adjustment block 20 can be arbitrary shape.
The width range of first row air drain 13 is 0.02mm~0.05mm.The quantity of second row air drain 14 is less than first exhaust
The quantity of slot 13.As shown in Fig. 3, the shape of first row air drain 13 is not limited to square groove, and the shape of second row air drain 14 is not
It is confined to cylinder groove.In the arc-shaped exhaust for doing 0.5mm depth at 5mm ~ 10mm apart from product material position.
Principle: flowing velocity of the plastic cement of melting in the type chamber of injection mold by mold exhaust effect, in type chamber
Air is arranged faster, and the plastic cement of melting flows faster in type chamber, is more smooth.Meanwhile the exhaust effect of mold additionally depends on
Seal degree when mold clamping；If the molding gap of male model and master mold is excessive when molding, although being conducive to exhaust, can go out
The case where plastic cement melted in existing mold overflows, generates batch peak flash；If the molding gap of male model and master mold is too small when molding,
Although the case where being overflowed to avoid the plastic cement melted in mold, but be unfavorable for being vented.
By the way that pressure-bearing adjustment block 20 is arranged in master mold.When molding, pressure-bearing adjustment block 20 is between male model and master mold.With mould
When, if pressure-bearing adjustment block 20 is blocked up, the exhaust effect of mold is influenced, pressure-bearing adjustment block 20 can be disassembled from master mold,
It is then sent for polishing, reduces the thickness of pressure-bearing adjustment block 20, thus to obtain suitable molding gap, to reach preferably exhaust effect
Fruit so that the plastic cement of melting at the thin-walled generation of type chamber in flow faster, it is more smooth, and then overcome injection molding to generate thin-walled and produce
Existing filling is difficult when product, also can be avoided product and generates batch peak flash.
It should be understood that various information are described in the utility model using term " first ", " second " etc., but these
Information should not necessarily be limited by these terms, these terms are only used to for same type of information being distinguished from each other out.For example, not departing from this
In the case where utility model range, " first " information can also be referred to as " second " information, and similar, " second " information can also be with
Referred to as " first " information.
The above is not limit the technical scope of the present invention, all real according to the utility model technology
Matter still falls within the technical solution of the utility model to any modification, equivalent variations and modification made by above embodiment
In range.
