Enter the vertically-mounted head for having air tube, described air tube in son to extend into die cavity, the middle part of the air tube is provided with passage vertically,
Described passage upper end communicates with die cavity, and the passage lower end communicates with the gas circuit of arrangement in male model, described male die insert
The L-type indentation, there of side is disposed with cast gate, and one end of the cast gate is connected with die cavity.
Used as one kind supplement to technical scheme described in the utility model, the head of described air tube extend into die cavity
Interior, the head of the air tube sinks to 2~3mm of product thickness.In intake process, the shaping of gas leakage effect product is prevented.
Used as one kind supplement to technical scheme described in the utility model, described male model enters positioned at gas circuit through male model
The location arrangements of son have sealing ring.
Used as one kind supplement to technical scheme described in the utility model, the upper end of described male die insert is close to cast gate
Side be disposed with product tip forming portion.
Beneficial effect：The utility model is related to a kind of mould of the auxiliary electroplated product of gas, and the meat at glue-feeder is thick to steal glue, effectively
Prevent at Jiao Kou produce gas trace, swash.Inlet Position selection is at the most advanced place of product, i.e. product tip forming portion side
Position, solves because inert gas enters the swash produced in mold cavity in product surface, and intake port shape is conducive to simplifying
Follow-up hot melting process, is conducive to the pressurize of product air pressure, prevents the shrink of product.Hot melt plug is convenient with product to be positioned, heat
It is molten simpler.

Specific embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation scope of the present utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Implementation method of the present utility model is related to a kind of mould of the auxiliary electroplated product of gas, as Figure 1-3, including phase interworking
The master mold and male model 7 of conjunction, the side that the described upper end of male model 7 is located at die cavity are provided with male die insert 4, are erected in the male die insert 4
Air tube 2 directly is installed, the head of described air tube 2 is extend into die cavity, and the middle part of the air tube 2 is provided with passage 9 vertically, described
The upper end of passage 9 communicated with die cavity, the gas circuit 6 of arrangement is communicated in the lower end of passage 9 and male model 7, described male die insert 4
The L-type indentation, there of side is disposed with cast gate 3, and one end of the cast gate 3 is connected with die cavity.
The head of described air tube 2 is extend into die cavity, and the head of the air tube 2 sinks to the 2~3mm of meat thickness of product 1.
Described male model 7 is located at gas circuit 6 has sealing ring 5 through the location arrangements of male die insert 4.
The upper end of described male die insert 4 is disposed with product tip forming portion 8 near the side of cast gate 3.
Embodiment
A kind of production technology of the auxiliary electroplated product of gas, specific operating procedure is as follows：
A () gas aided injection mould is divided into injection phase, inflation phase, gas pressurize phase and demoulding phase, the phase is molded first, will be quantitative
The plastics of molten condition be expelled in mold cavity by cast gate 3；
(b) and then the inflation phase, interim, the rear stage is being molded, different time injects high-pressure inert gas, gas from gas circuit 6
Inject big pressure and have to be larger than injection pressure；
(c) then, the gas pressurize phase, inside product 1 by gas filling after, gas continuingly acts on the hollow bulb of product 1
Point；
D () is followed by the demoulding phase, with the completion of cooling cycle, the gas pressure of mould is down to atmospheric pressure, product 1
Ejected by die cavity；
E the product 1 of () shaping is placed under special fixture, using the air inlet and flash mouthful of the hot melt blocking products 1 of plug 10,
Heated, hot melt plug 10 includes lid 12 and plug portion 13, and the described upper center of lid 12 is vertically-mounted plug portion
13, the upper surface of lid 12 is disposed with a circle small boss 11 around plug portion 13；
F () is last, carry out the electroplating surface treatment of product 1；Wherein, at the most advanced place of product 1, i.e., Inlet Position selects
