Summary of the invention
based on the problems referred to above, the utility model object is to provide a kind of injection mold apparatus for hot flow path, and it can solve the outlet of open nozzles head due to the too fast problem that causes putty of heat radiation.
in order to solve these problems of the prior art, the technical scheme that the utility model provides is:
a kind of injection mold apparatus for hot flow path, it comprises nozzle, upper die and lower die, described patrix and described counterdie form die cavity, described nozzle is arranged on patrix, described nozzle comprises nozzle body and nozzle head, it is characterized in that: the top of described die cavity is provided with cast gate, the outlet of described nozzle head is corresponding with described cast gate, between described outlet and described cast gate, has cavity.
further, described nozzle head outside has the step of annular, and step screw thread is set on described step, and the inside of described nozzle head is inverted conical cavity, and the bottom of described conical cavity is communicated with described outlet.
further, the inwall of described nozzle body is provided with inner thread, and described nozzle head is tightened on described nozzle body by described inner thread.
further, described patrix arranges seal, and described seal and described nozzle head match, and described nozzle body and described seal have contact-making surface, and described contact-making surface makes to form described cavity between described nozzle head and described patrix.
further, described patrix and described counterdie also arrange cooling water hole.
with respect to scheme of the prior art, the utility model has the advantages that:
1. adopt technical solutions of the utility model, nozzle head is tightened on nozzle body, then nozzle head is fixed in the seal of patrix, make to there is certain distance between nozzle head and cast gate and form cavity, nozzle head is with not directly contact of mould like this, nozzle head outlet heat can not taken away by mould, can, because of the too low putty problem that occurs of temperature, not affect production efficiency;
2. adopt the technical solution of the utility model, reduce nozzle head outlet and cast gate putty, can save injection raw material, improve the quality of products.
Brief description of the drawings
in order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
fig. 1 is the structural representation of a kind of injection mold apparatus embodiment for hot flow path of the utility model;
fig. 2 is the profile of a kind of injection mold apparatus nozzle head for hot flow path of the utility model;
wherein: 1, nozzle; 11, nozzle body; 12, nozzle head; 121, nozzle head outlet; 122, step; 123, conical cavity; 2, patrix; 3, counterdie; 4, die cavity; 5, cast gate; 6, cavity; 7, seal; 8, cooling water hole.
Detailed description of the invention
below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiment are not limited to limit scope of the present utility model for the utility model is described.The implementation condition adopting in embodiment can be done further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
referring to Fig. 1, for the structural representation of the embodiment of a kind of injection mold apparatus for hot flow path of the utility model, it comprises nozzle 1, patrix 2 and counterdie 3, patrix 2 and counterdie 3 coordinate formation die cavity 4, and the top of die cavity 4 arranges cast gate 5, and nozzle 1 is fixed on patrix 2, nozzle 1 comprises nozzle body 11 and nozzle head 12, nozzle head outlet 121 is corresponding with cast gate 5, between nozzle head outlet 121 and cast gate 5, has certain distance, on patrix 2 and counterdie 3, cooling water hole 8 is also set.
the outside of nozzle head 12 has the step 122 of annular, on this step 122, step screw thread is set, and the inwall of corresponding nozzle body 11 is provided with inner thread, and nozzle head 12 is tightened on nozzle body 11 by inner thread; The inside of nozzle head 12 is inverted conical cavities 123, and the bottom of this conical cavity 123 is communicated with nozzle head outlet 121, and molten plastic arrives nozzle head outlet 121 through the conical cavity 123 of nozzle head 12, then enters die cavity 4 through cast gate 5.
lower the temperature in injection moulding process for fear of molten plastic too fast, at patrix 2, seal 7 is set, the shape of seal 7 and nozzle head 12 match, nozzle head 12 is fixed in sealing mouth 7, nozzle body 11 has contact-making surface with the top of seal 7 like this, and this contact-making surface makes to form cavity 6 between nozzle head 12 and patrix 2.
introduce operation principle of the present utility model below, nozzle head is tightened in nozzle body by screw thread, then nozzle head is fixed in the seal of patrix, make nozzle head outlet corresponding with gate location, molten plastic is pressed in nozzle by injection pressure, and because nozzle head does not directly contact with mould, the molten plastic of nozzle head outlet can be because of the too fast putty that causes of cooling, molten plastic enters die cavity through nozzle head and cast gate, completes injection moulding.
