Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
The utility model provides a kind of special open dispensing mouth nozzle of deep chamber product, and the starting point of the technical program is
Exclusively for the open dispensing mouth nozzle of deep chamber product 7 research and development, for realizing the production model of zero cold burden, customer service is needed once
The problem of several aspects；
Problem one：The interference problem of deep cavity mould cavity, the technical program use extended type diversion spindle structure, diversion spindle
Lengthening range can be at (5~20mm), according to the actual grade of product cavity, freely to design, diversion spindle inner flow passage, can be with
Using 2 kinds of modes, diversion spindle inner flow passage structure 1, diversion spindle inner flow passage structure 2 31 are such as schemed, 1 effect of mode：Plastics are detained
Layer 9 always, is conducive to colour changing with plastics flow direction, but the plastics of molten condition and area that mode is in direct contact are big, meeting
There is a degree of temperature loss, influence plastic flow property, actual needs increases forming temperature to solve；2 effect of mode：Runner
Inside diversion spindle, diversion spindle head is extended to, at the cast gate, area that the plastics of molten condition are contacted with mode
It is small, be conducive to fill, but since retention layer is behind plastic emitting direction, be unfavorable for colour changing；
Problem two：The heat conducting problem on diversion spindle head after lengthening, for this problem, application scheme combines application
The exclusive high heat conduction of people, the structure of high heat-insulated nozzle, is made, and lead using materials such as highly heat-conductive materials (such as BeCu.TZM)
Stream shuttle can be conducive to the conduction of heat directly with heater contacts；The sealing face that nozzle is contacted with mold, using (TC4) etc.
Highly insulative material makes, and reduces heat loss to the greatest extent, ensures the heat insulation effect of diversion spindle material；
The utility model provides a kind of special open dispensing mouth nozzle of deep chamber product, and concrete scheme is：
Diversion spindle uses the material of high heat conduction, is connect by the way of thread with core, in 10 inlet of thread junction,
There is one section of smart sizing face 2, for being matched with the smart sizing face 2 on nozzle core 1, to ensure the same of 2 parts
Heart degree ensures that runner joint does not have dead angle, and the spur of diversion spindle is made of main part 4 and chamfered portion 6, main part 4
Length dimension can be adjusted freely (5-25mm), and 6 angle of spur chamfered portion can adjust in the range of (30-60 degree), water conservancy diversion
The inner flow passage of shuttle can have 2 kinds of modes, mode one：It is to beat gum outlet close to 1 end of nozzle core in diversion spindle, gum outlet
Quantity can be 1 or multiple, the structure of this runner, it is ensured that plastics retention layer 9 is consistent with the direction of plastic emitting, favorably
In the colour changing effect of plastics；Mode two：To beat gum outlet close to spur end in diversion spindle, the quantity of gum outlet can be 1 or
Person is multiple, this flow passage structure, plastics retention layer 9 with plastic emitting direction on the contrary, be unfavorable for colour changing, but because gum outlet is close
At cast gate, the temperature loss of plastics is small, is conducive to the flowing of plastics；2 kinds of modes cut both ways, and can be selected according to actual conditions
With.
Application scheme has the traditional technology of the preferred option of the open dispensing mouth hot flow path of many packaging industries instantly
Scheme has no idea to accomplish the effect of zero cold burden, and application scheme can realize zero cold burden, simultaneously as be high heat conduction, it is high heat-insulated
Structure, the temperature of nozzle head diversion spindle ensured well enables the temperature at cast gate to reach plastic injection temperature range.
By the application of the dedicated open dispensing mouth nozzle of deep chamber product, perfectly solves deep chamber product upside-down mounting into glue
Zero cold burden problem, in combination with the high heat-insulated nozzle arrangements of high heat conduction, forming temperature is allowed to be controlled effectively, increases product
Injection molding window, reduce tune machine difficulty；It is the preferred option of the open dispensing mouth hot flow path of many packaging industries instantly.
It is worth noting that, the scheme of the connection mode of diversion spindle and nozzle head further includes forcing press mechanical interference,
Soldering connection coordinates.Diversion spindle is made of BeCu or TZM, and the sealing face 12 that the head of diversion spindle is contacted with mold uses
TC4 highly insulative materials make.
In short, the technical solution of application scheme essentially consists in：
1) structure of extended type diversion spindle；
2) structure (remarks of diversion spindle inner flow passage：Diversion spindle gum outlet quantity can be with 1 or multiple)；
3) high heat conduction, high heat insulation structural.
Although the utility model is disclosed as above with preferred embodiment, so it is not limited to the utility model, any
Those skilled in the art, without departing from the spirit and scope of the utility model, when can make a little modification and it is perfect, therefore this
The protection domain of utility model, which is worked as, is subject to what claims were defined.
