The film that the blown film head blew out is even fine and smooth more, and the material also more has toughness, and the transparency is also better.
Description
Technical field
The utility model relates to a kind of inflation film manufacturing machine, is specifically related to a kind of blown film head on inflation film manufacturing machine.
Background technology
Inflation film manufacturing machine is a kind of machine plastic pellet heating and melting being blown out again film.The quality of film blowout depends on the structure of inflation film manufacturing machine blown film head, therefore inflation film manufacturing machine manufacturer is very high for the structural requirement of blown film head in R&D process, but the inadequate uniform and smooth of film of its blown film head of inflation film manufacturing machine general in the market blowout, the structure of source just from blown film head of these problems is reasonable not.
Summary of the invention
In view of the deficiency that prior art exists, the utility model innovation provides a kind of rational in infrastructure, once can blow out the inflation film manufacturing machine blown film head of the film of three layers of uniform and smooth.
The blown film head of this inflation film manufacturing machine includes mould cylinder, die cap, core rod head and core rod, described die cap is installed on mould cylinder, in described die cap and mould cylinder, there is through cavity volume, described core rod head is fixedly connected on core rod, described core rod and core rod head are located in cavity volume matchingly, described core rod is fixedly connected with mould cylinder, blown film runner is formed between the front portion of described core rod head and die cap, it is characterized in that: described core rod has syllogic round platform stage structure, the upper round platform of described core rod is fixedly connected with core rod head, described upper round platform overcoat has internal mould tub, described internal mould tub lower end is placed on round platform, intermediate gap is formed between upper end and core rod head, first flow is formed between inwall and upper round platform, described internal mould tub overcoat has exterior mould, described exterior mould lower end is placed on lower round platform, lower gap is formed between upper end and core rod head, the second runner is formed between inwall and exterior mould, the 3rd runner is formed between outer surface and mould cylinder inwall, described lower gap, intermediate gap and blown film runner form sprue, described first flow, second runner and the 3rd runner are communicated with sprue, three through holes communicated with the external world are provided with in described core rod, described three through holes are corresponding and first flow respectively, second runner and the 3rd runner communicate.
Have syllogic column type injection molding cavity in described core rod, upper injection molding cavity is communicated with first flow by the first through hole, and middle injection molding cavity is by the second through hole and the 3rd flow passage, and lower injection molding cavity is by third through-hole and the second flow passage.
Described die cap is fixedly connected with mould cylinder by bolt, and described core rod is fixedly connected with mould cylinder by bolt.
The blown film head of a kind of inflation film manufacturing machine provided according to the utility model, a sprue is pooled by three runners, therefore the film of blown film head blowout just has three layers, and due to interior die sleeve and outer die casing be that staged is located, runner is more accurate, therefore from three runners film uniform and smooth more out, material also has more toughness, and transparency is also better; In addition, the syllogic column type injection molding cavity of core rod contributes to being connected with two injection screws, and the benefit of two injection screws is that the material of mesonexine film comes from a screw rod, and the film of blowout so also can be impelled more balanced.
Accompanying drawing explanation
Accompanying drawing 1 is sectional view of the present utility model.
Detailed description of the invention
As shown in Figure 1, the blown film head of this inflation film manufacturing machine includes mould cylinder 6, die cap 1, core rod head 2 and core rod 3, die cap 1 is arranged on mould cylinder 6 by bolt, in die cap 1 and mould cylinder 6, there is through cavity volume, core rod head 2 is fixedly connected on core rod 3, and both are located in cavity volume matchingly, core rod 3 and mould cylinder 6 are bolted to connection.
Blown film runner is formed between the front portion of core rod head 2 and die cap 1, film just blows out from this blown film runner, in order to blow out three-layer thin-film, core rod 3 is designed to syllogic round platform stage structure by the utility model, wherein the upper round platform of core rod is fixedly connected with core rod head 2, middle round platform is provided with internal mould tub 4, internal mould tub 4 is enclosed within outside round platform, intermediate gap is formed between internal mould tub 4 upper end and core rod head 2, first flow is formed between inwall and upper round platform, internal mould tub 4 overcoat has exterior mould 5, exterior mould 5 lower end is placed on lower round platform, lower gap is formed between upper end and core rod head 2, the second runner is formed between inwall and exterior mould, the 3rd runner is formed between outer surface and mould cylinder 6 inwall, lower gap, intermediate gap and blown film runner form sprue, first flow, second runner and the 3rd runner are communicated with sprue, i.e. first flow, second runner and the 3rd runner flow into blown film runner through intermediate gap and lower gap, finally from blown film runner blowout three-layer thin-film.
Certainly, be provided with three through holes communicated with the external world in core rod 3, three through holes are corresponding respectively to communicate with first flow, the second runner and the 3rd runner.Conveniently injection screw access, there is in core rod 3 of the present utility model syllogic column type injection molding cavity, upper injection molding cavity is communicated with first flow by the first through hole, middle injection molding cavity by the second through hole and the 3rd flow passage (owing to misplacing, Fig. 1 sectional view is failed to demonstrate it and is communicated with), and lower injection molding cavity is by third through-hole and the second flow passage, the syllogic column type injection molding cavity of core rod 3 contributes to being connected with two injection screws, the benefit of two injection screws is that the material of mesonexine film comes from a screw rod, and the film of blowout can be made so more balanced.
