Description
Technical field
It the utility model is related to technical field of mold, more particularly to a kind of waterproof Kato injection mold.
Background technology
Kato is that one kind is applied in electronic equipment（Especially mobile phone）In parts, for carrying electronic card, such as SIM
Card, TF card, SD card etc..As shown in figure 1, electronic equipment is in order to reach water-proof function, it will usually which sealing ring A is set in Kato B
Outside, form waterproof Kato.
Existing waterproof Kato assembly method is：After Kato B and sealing ring A is machined respectively, sealing ring A is set in
On Kato B.The waterproof Kato that this assembly method is produced, the combination between sealing ring and Kato is not close, close during use
Seal easily loosens, and causes water-proof function to fail, and then causes electronic equipment to be intake.
Utility model content
The technical problems to be solved in the utility model is according to above-mentioned the deficiencies in the prior art, there is provided one kind can allow sealing
Enclose the injection mold for being combined with Kato even closer.
The technical solution of the utility model is as follows：
A kind of waterproof Kato injection mold, including pressing plate, upper mould and the lower mould set from top to bottom successively；The lower mould
Upper surface sets some Kato mounting grooves and some lower half ring cavities, the lower half ring cavity to be connected with the Kato mounting groove；It is described
Upper mould lower surface is provided with upper half ring cavity corresponding with the lower half ring cavity, and the lower half ring cavity forms close with the upper half ring cavity
Seal die cavity.
Further, be provided with positioning boss in the middle part of the Kato mounting groove, the upper mould lower surface be provided with it is described
The positioning concave stations that positioning boss coordinates.
Further, distribution is provided with positioning trough around the Kato mounting groove, the upper mould lower surface be provided with
The positioning convex strip that the positioning trough coordinates.
Further, the lower mould upper surface is provided with pin die cavity, and the pin die cavity connects with the lower half ring cavity.
Further, the upper mould upper surface is provided with material pond, and the material pond is connected by gum intaking passage and the upper half ring cavity
It is logical；The pressing plate lower surface is provided with presents a theatrical performance as the last item on a programme with the material pond form fit.
Further, the runner and institute are passed through by flow passage, the gum intaking passage between some upper half ring cavities
State the connection of upper half ring cavity.
Compared with prior art, the utility model has the advantages that：By the way that Kato is arranged in injection mold,
Sealing ring is directly sleeved on outside Kato in sealing ring mold cavity forming, sealing ring is combined with Kato even closer, is avoided card
Sealing ring loosens and fallen down when support uses.

Embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
Type is described in further detail.
As shown in Figure 2-5, embodiment provided by the utility model, a kind of waterproof Kato injection mold, including successively from upper
To the pressing plate 10, upper mould 20 and lower mould 30 of lower setting；The lower upper surface of mould 30 sets some Kato mounting grooves 31 and some lower half
Ring cavity 32, lower half ring cavity 32 connect with Kato mounting groove 31；The upper lower surface of mould 20 is provided with and 32 corresponding upper half of lower half ring cavity
Ring cavity 21, lower half ring cavity 32 form sealing ring die cavity with upper half ring cavity 21.Wherein, before injection, Kato is positioned over Kato mounting groove
In 31, upper mould 20 and lower mould 30 close, and make sealing die cavity around Kato.
As shown in Figure 3 and Figure 5, the middle part of Kato mounting groove 31 is provided with positioning boss 33, the upper lower surface of mould 20 be provided with
The positioning concave stations 22 that positioning boss 33 coordinates.The distribution of the surrounding of Kato mounting groove 31 is provided with positioning trough 34, the upper lower surface of mould 20
It is provided with the positioning convex strip 23 coordinated with positioning trough 34.Wherein, when upper mould 20 assembles with lower mould 30, positioning boss 33 is inserted in
In positioning concave stations 22, positioning convex strip 23 is inserted in positioning trough 34, makes mould 20 and the lower accurate positioning of mould 30.
As shown in figure 3, the lower upper surface of mould 30 is provided with pin die cavity 35, pin die cavity 35 connects with lower half ring cavity 32.Its
In, after injection molding, pin is formed in pin die cavity 35, pin is used to pull out waterproof Kato, conveniently stripped.
As shown in Fig. 2 the upper upper surface of mould 20 is provided with material pond 24, material pond 24 is connected by gum intaking passage 25 and upper half ring cavity 21
It is logical；Pressing plate 10 lower surface is provided with presents a theatrical performance as the last item on a programme with the form fit of material pond 24（It is not drawn into figure）.Lead between some upper half ring cavities 21
Cross runner 26 to connect, gum intaking passage 25 is connected by runner 26 with upper half ring cavity 21.Material pond 24 is used for the rubber for bearing molten condition
Or silica gel, by the extruding presented a theatrical performance as the last item on a programme to rubber or silica gel, make rubber or silica gel from gum intaking passage 25, runner 26 enter sealing die cavity and
In pin die cavity 35.
In the present embodiment, by the way that Kato is arranged in injection mold, sealing ring directly covers in sealing ring mold cavity forming
Outside Kato, sealing ring is combined with Kato even closer, avoid Kato using when sealing ring loosen fall down.
Above disclosed is only the utility model preferred embodiment, can not limit the utility model with this certainly
Interest field, therefore equivalent variations made according to the utility model claims still belong to the scope that the utility model is covered.
