Abstract
The utility model discloses a constant-temperature heat nozzle structure for a light guide plate. The constant-temperature heat nozzle structure comprises a heat nozzle body, a nozzle core, a sprue lining bush and a heater, wherein the nozzle core is arranged at the tail end of a flow channel in the heat nozzle body; the heater is sleeved at the periphery of the heat nozzle body; the sprue lining bush is sleeved on the nozzle core; the tail end of the sprue lining bush protrudes out of the heat nozzle body; the constant-temperature heat nozzle structure also comprises a heat insulation cover which is arranged on the heater of the heat nozzle body and at the periphery of the sprue lining bush. According to the scheme, the problems that the nozzle core of the heat nozzle is salivated, the wire is drawn and a stub bar is broken because of unstable temperature of the heat nozzle in the injection molding process of the light guide plate are solved.
Description
Technical field
The utility model belongs to the TOP-TIP field, relates to a kind of LGP constant temp. heating mouth structure.
Background technology
The hot mouth structure that uses during the LGP injection mo(u)lding as shown in Figure 1, comprise a hot mouth body 1, mouth core 2 and gate bush 3, mouth core 2 is arranged at the end of hot mouth body 1 inner flow passage 4, and gate bush 3 is sheathed on the mouth core 2, and the end of gate bush 3 protrudes from hot mouth body 1.In the LGP injection molding process, because hot mouth high temperature melts state so that the plastics in the runner are heat, and the gate bush of hot mouth is just in mouth core position, long-pending less with mould contact surface, cause dispelling the heat bad, hot mouth temperature is unstable, after injection moulding is finished, when mould is opened the demoulding, the material excess Temperature at hot mouth mouth core Jiao Kou place, the easy wire drawing of stub bar; Or cause hot mouth mouth core salivation, if the fracture head will appear in stub bar and product junction excess Temperature, these problems all can affect the moulding of next product.
Therefore, how addressing the above problem, is the content that the utility model will be studied.
Summary of the invention
The utility model provides a kind of LGP constant temp. heating mouth structure, and its purpose mainly is to solve in the LGP injection moulding process, causes the problem of the salivation of hot mouth mouth core, wire drawing and the fracture of material silk owing to hot mouth temperature is unstable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of LGP constant temp. heating mouth structure, comprise a hot mouth body, mouth core and heater, and the mouth core is arranged at the end of hot mouth body inner flow passage, and heaters set is located at the periphery of hot mouth body; Also comprise a collet, this collet is located at the periphery of hot mouth body upper heater, and is sheathed on the mouth core.
Related content in the technique scheme is explained as follows:
1, in the such scheme, outer the placing of described hot mouth body also is provided with the temp.-sensing wire installing hole.Be provided with temp.-sensing wire in this temp.-sensing wire installing hole, be used for the temperature of sense heat mouth body.
2, in the such scheme, the week of the end of described collet upwards offers screwed hole, and this collet is fixed on the hot mouth body through this screwed hole screw thread.
Because the utilization of the technical program, the utility model compared with prior art has following advantages:
1, the utility model is set up collet in the periphery of hot mouth body and mouth core, this collet contacts cooperation with the mould large tracts of land, so that good heat dissipation effect, collet wraps hot mouth body integral body, can be good at keeping the temperature constant of hot mouth body constant, effectively solve the problem of the salivation of hot mouth mouth core, wire drawing and the fracture of material silk.
2, the utility model is simple in structure, practicality, and easy to process, processing cost is lower.
Description of drawings
Accompanying drawing 1 is hot mouth structure schematic diagram in the prior art;
Accompanying drawing 2 is the utility model structural representation.
In the above accompanying drawing: 1, hot mouth body; 2, mouth core; 3, gate bush; 4, runner; 5, collet; 6, heater; 7, temp.-sensing wire installing hole; 8, screwed hole.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment:
As shown in Figure 2, a kind of LGP constant temp. heating mouth structure comprises a hot mouth body 1, mouth core 2 and heater 6, and mouth core 2 is arranged at the end of hot mouth body 1 inner flow passage 4, and heater 6 is set in the periphery of hot mouth body 1; Also comprise a collet 5, this collet 5 is located at the periphery of hot mouth body 1 upper heater 6, and is sheathed on the mouth core 2.
Outer the placing of described hot mouth body 1 also is provided with temp.-sensing wire installing hole 7, is provided with temp.-sensing wire in this temp.-sensing wire installing hole 7, and more family carries out the temperature control of hot mouth body 1 accurately.
The week of the end of described collet 5 upwards offers screwed hole 8, and this collet 5 is fixed on the hot mouth body 1 through these screwed hole 8 screw threads.
Collet 5 is set up in periphery at hot mouth body 1 and mouth core 2, this collet 5 contacts cooperation with the mould large tracts of land, so that good heat dissipation effect, collet 5 wraps hot mouth body 1 integral body, can be good at keeping the temperature constant of hot mouth body 1 constant, effectively solve the problem of salivation, wire drawing and the fracture of material silk of hot mouth mouth core 2.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
