Abstract
The utility model relates to a mold core structure of a film blowing machine used for blowing plastic particles which melt after being heated into films. The mold core structure comprises a flow dividing area, a compression area and a formation area, wherein a grid plate is arranged at the inlet of the flow dividing area and mounted on a mold body in which a flow dividing spreader is arranged; the mold body is supported on a mandrel support; the flow dividing area is further provided with an adjusting screw I; the compression area is provided with an adjusting screw II; the formation area is provided with a mandrel and a finish mold. The mold core structure is reasonable in design; the screw I and the screw II are respectively used for adjusting the cavity space of the flow dividing spreader and the mold body in the flow dividing area and the cavity space of the flow dividing spreader and the mandrel support in the compression area, so that the quality of blown films is good.
Description
Technical field
The utility model relates to a kind of inflation film manufacturing machine mold insert structure, for the plastic pellet after heating and melting is blown out to film.
Background technology
Traditional inflation film manufacturing machine mold insert structure, spreader in shunting zone and the cavity space of die body, in compressional zone, the cavity space of spreader and core support is all unadjustable, and the plastic particles of unlike material needed hydraulic pressure in the process of extruding film forming is different, thereby affects film quality.
Utility model content
In order to overcome the shortcoming of prior art, the utility model provides a kind of inflation film manufacturing machine mold insert structure.
Technical solutions of the utility model are as follows:
A kind of inflation film manufacturing machine mold insert structure, comprise shunting zone, compressional zone and shaping area, described shunting zone entrance is screen, described screen is installed on die body, described die body inside is provided with spreader, and described die body is supported on core support, and described shunting zone is also provided with adjustment screw one, described compressional zone is provided with adjustment screw two, and described shaping area is provided with core and mouthful mould.
The utility model beneficial effect is: reasonable in design, and screw one and screw two regulate respectively the cavity space of spreader and core support in the cavity space of spreader in shunting zone and die body and compressional zone, thus blown film quality is good.
