Abstract
The utility model relates to a discharging die and particularly relates to a special plastic discharging die. A die cavity port of the special plastic discharging die disclosed by the utility model is of an arch shape at the middle and of a gradually-contacted sharp shape at two sides; and when extruding discharging is carried out, two sides of the die cavity are sharp and the middle of the die cavity is arched, so that the phenomenon that two sides of the special plastic discharging die is thick at two sides and thin at the middle can be avoided and further the uniformity and consistency of the middle and two sides of the special plastic discharging die are ensured.
Description
Technical field
The utility model relates to a kind of discharging mode, particularly a kind of special-shaped plastics discharging mode.
Background technology
Produce IC electronic product packing carrier band at present and adopt flat mouthful of plastics material mould usually.Flat mouthful of plastics material mould of this kind adopts square discharging opening, and after plastics got into charging aperture, plastics were when flat mouthful of depanning die cavity extruding and discharging; Can not keep the harmony in the whole die cavity, and produce intermediate thin, the phenomenon that both sides are thick; Plastics on the both sides of discharging opening constantly thicken naturally, thereby make the plastics on both sides become underproof waste product, have so both increased cost; Reduce product and quality again, reduced production efficiency widely.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, easy to operate and can guarantee in the middle of and the balanced consistent special-shaped plastics discharging mode of both sides discharging.
The purpose of the utility model realizes through following technical scheme: special-shaped plastics discharging mode; Comprise mould mouth, discharging opening and die cavity, die cavity is provided with a die cavity mouth, and the die cavity mouth communicates with discharging opening; It is characterized in that: overarch in the middle of the described die cavity mouth, both sides are apered to pointed.
As a kind of improvement of the utility model, described special-shaped plastics discharging mode also comprises and can cooperate screw that discharging mode is installed in the screw hole on the board.
The beneficial effect that the utility model is obtained: overarch in the middle of the special-shaped plastics discharging mode die cavity mouth of the utility model; Both sides are apered to pointed; During extruding and discharging, since die cavity mouth both sides point, intermediate arches; The phenomenon of the thick intermediate thin in both sides just can not occur, thereby guarantee middle and the balanced unanimity of both sides discharging.
Description of drawings
Fig. 1 is the perspective view of the utility model
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to set forth:
Referring to Fig. 1, the special-shaped plastics discharging mode of the utility model comprises mould mouth 1, discharging opening 2, die cavity and can cooperate screw that discharging mode is installed in the screw hole 3 on the board.Die cavity is provided with a die cavity mouth 4, and die cavity mouth 4 communicates with discharging opening 2, overarches in the middle of the die cavity mouth, and both sides are apered to pointed.
The special-shaped plastics discharging mode die cavity mouth of the utility model is middle to overarch, and both sides are apered to pointed, and during extruding and discharging, because die cavity mouth both sides point, intermediate arches just the phenomenon of the thick intermediate thin in both sides can not occur, thereby assurance is middle and the both sides discharging is balanced consistent.
According to the announcement and the instruction of above-mentioned specification, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present invention some modifications and the change of the utility model.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the utility model is not constituted any restriction.
Claims (2)
1. special-shaped plastics discharging mode comprises mould mouth, discharging opening and die cavity, and die cavity is provided with a die cavity mouth, and the die cavity mouth communicates with discharging opening, it is characterized in that: overarch in the middle of the described die cavity mouth, both sides are apered to pointed.
2. special-shaped plastics discharging mode as claimed in claim 1 is characterized in that: described special-shaped plastics discharging mode also comprises and can cooperate screw that discharging mode is installed in the screw hole on the board.
