Abstract
The utility model discloses an extrusion shaping die. A cavity is formed in the middle of the extrusion shaping die; at least one narrow part is arranged on the periphery of the cavity; blowing plates are arranged in the positions, corresponding to the at least one narrow part, of an inlet end surface of the extrusion shaping die; flow channels are arranged in the blowing plates; opening slots communicated with the flow channels are formed in the at least one narrow part; and the flow channels are connected with a cold air device. According to the extrusion shaping die, air flow blown from the cold air device enters the channels of the blowing plates and is blown to the narrow parts of a profile through the opening slots communicated with the flow channels, so that the narrow parts of the profile about to enter the cavity are cooled in advance, accordingly, the profile passes the extrusion shaping die more easily, the blockage is prevented, and the production continuity is guaranteed.
Description
Technical field
The utility model relates to a kind of mould, refers to especially a kind of calibrator.
Background technology
In extruding-out and shape-fixating machine, conventionally by die head, be connected with calibrator, raw material is heated by extruding machine barrel, the section bar that screw rod is expressed into die head formation by plastic melt is expressed into the calibrator being positioned on shaping platform again, this calibrator is connected with vacuum system with the chilled water system on shaping platform, by this calibrator, section bar is carried out to vacuum cooled to be fixed to finished product.Due to extruder and plastic melt existence unstability to a certain degree, make plastic melt from die head flows out, the wall thickness of melt has certain difference, causes entering after calibrator, place that can be less in gap forms to be stopped up, and has influence on the continuity of production.
Utility model content
The utility model proposes a kind of calibrator, solved the problem that plastic melt stops up.
The technical solution of the utility model is achieved in that
A kind of calibrator, its middle part is provided with a die cavity, the periphery of this die cavity has at least one narrow positions, the narrow positions of the corresponding die cavity of entrance face of described calibrator is provided with blow-down panel, in described blow-down panel, be provided with runner, and in narrow bit position, being provided with the open slot being communicated with runner, described runner is connected with a cooling air unit.
Preferred version is that the shape of described blow-down panel inner face is corresponding with the shape of the narrow positions of its position.
Preferred version is that described open slot is the slit extending longitudinally along blow-down panel.
Preferred version is that the outer end of described runner is connected with tube connector, by a body, this tube connector is connected with cooling air unit.
Preferred version is that described runner extends inwardly to the narrow positions near die cavity by the outer end of blow-down panel.
Preferred version is, the top of described calibrator has an air cavity, and is provided with in the top of air cavity the pore being communicated with air cavity, and described air cavity is connected with cooling air unit, and described pore is connected with the runner of blow-down panel.
Preferred version is, the narrow positions of described die cavity is a plurality of, and described blow-down panel is 4.
The beneficial effects of the utility model are:
Calibrator in the utility model, the air-flow being blown out by cooling air unit enters in the runner of blow-down panel, by the open slot being communicated with runner, blowed to again the narrow positions of section bar, the narrow positions that makes to be thus about to enter the section bar in die cavity is first carried out cooling, thereby make this section bar more easily by this calibrator, prevent from stopping up, guaranteed the continuity of producing.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the entrance face schematic diagram of the utility model calibrator one preferred embodiment.
In figure:
10, air cavity; 12, pore; 20, die cavity; 40, narrow positions; 50, blow-down panel; 52, runner; 54, open slot; 60, tube connector.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the calibrator of the present embodiment, its top has an air cavity 10, and is provided with in the top of air cavity 10 pore 12 being communicated with air cavity 10.The middle part of this calibrator has a die cavity 20, and the shape of this die cavity 20 is identical with the shape of Prefabricated.In the present embodiment, the periphery of this die cavity 20 has 10 narrow positions 40.The entrance face of this calibrator is provided with four blow-down panel 50.Each blow-down panel 50 correspondence is located at the narrow positions 40 of die cavity 20, and the shape of the shape of its inner face and the die cavity of its position 20 is corresponding, and the shape of outer face is alignd with calibrator limit end.In the present embodiment, specifically the example that is configured to the blow-down panel 50 in the calibrator upper right corner describes.These blow-down panel 50 inside are provided with two parallel runners 52, and each runner 52 extends inwardly to the narrow positions 40 near die cavity 20 by the outer end of blow-down panel 50, and described blow-down panel 50 is provided with open slot 54 in the inside of narrow positions 40.Described open slot 54 is the slits extending longitudinally along blow-down panel 50, and the runner 52 corresponding with it is connected.The outer end of each runner 52 is connected with a tube connector 60.During use, by a body (not shown), tube connector 60 is connected with the pore 12 of this extrusioning shaping die tip, the section bar that calibrator is extruded by die head will enter in this extrusioning shaping mold process, cold airflow in air cavity 10 enters in the runner 52 of blow-down panel 50 by pore 12 and body, then blows to section bar by the open slot 54 being communicated with runner 52.Because open slot 54 correspondences are located at the narrow positions 40 of die cavity 20, corresponding with the narrow positions 40 of section bar, the narrow positions 40 that makes to be thus about to enter the section bar in die cavity 20 is first carried out cooling, thereby makes this section bar more easily by this calibrator, prevent from stopping up, guaranteed the continuity of producing.
During concrete enforcement, the number of described blow-down panel 50 and shape are not limited to the situation of the present embodiment, it can be according to the shape of die cavity 20 and corresponding change, only on die cavity 20, corresponding narrow positions 40 is provided with blow-down panel 50, and the shape of the inner face of blow-down panel 50 is corresponding with the shape of the die cavity of its setting position 20.The number of blow-down panel 50 upper runners 52 and shape are also not limited to the situation of the present embodiment, and it can two also can be one or more, and it also changes according to the number of the narrow positions 40 on die cavity.Described runner 52 can connect cooling air unit by the air cavity of calibrator itself, also can separately directly be connected with an outside cooling air unit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
