Disclosure of Invention
The utility model discloses the technical problem that will solve lies in: a blow molding machine head for synthetic resin is provided which solves the problems of non-uniform film thickness and occurrence of split lines of material flow.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides a blowing machine head for synthetic resin, includes the organism, the bottom fixedly connected with bush of organism, the runner that is linked together with the bush is seted up to the bottom of organism, the stirring chamber has been seted up at the top of runner, the inside of stirring chamber, runner and bush is provided with the plug jointly, be provided with thick clearance of membrane between the inner wall of plug and runner and bush, the top and the organism of plug rotate to be connected, the plug is located the stirring intracavity lateral wall fixedly connected with a plurality of evenly distributed's of dialling the board, the feed inlet that is linked together with the stirring chamber is seted up to one side of organism.
As a preferable example, the outer side wall of the core rod located in the flow channel is fixedly connected with three slide bars which are uniformly distributed, one ends of the three slide bars are all connected with the inner wall of the flow channel in a sliding manner, a spiral sleeve is fixedly sleeved on the part of the core rod located in the port die, and a gap is arranged between the spiral sleeve and the inner wall of the port die.
As a preferred example, an air inlet is formed at the axis of the mandrel, a rotary joint is fixedly connected to the top of the machine body, and the air inlet is communicated with the rotary joint.
The utility model has the advantages that:
1. the utility model discloses the material stream that will just get into in the aircraft nose stirs in the stirring intracavity for the material stream can even distribution and flow in the runner, thereby make the film thickness who makes even.
2. Through the setting of slide bar, the terminal slip on the runner of slide bar in the rotation process of plug plays the effect of supporting the plug, prevents that the plug from producing the slope under the effect of material flow, causes the thickness of film inhomogeneous.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a sectional view taken along line a-a of fig. 1.
In the figure: the extrusion die comprises a mouth die 1, a machine body 2, an extruder 3, a rotary joint 4, a stirring cavity 5, a shifting plate 6, a flow channel 7, a slide rod 8, a spiral sleeve 9 and a core rod 10.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-2, a blowing machine head for synthetic resin, including a machine body 2, a neck ring mold 1 is fixedly connected to the bottom of the machine body 2, a flow channel 7 communicated with the neck ring mold 1 is provided to the bottom of the machine body 2, a stirring chamber 5 is provided to the top of the flow channel 7, a core rod 10 is provided to the inside of the stirring chamber 5, the flow channel 7 and the neck ring mold 1 together, a film thickness gap is provided between the inner walls of the core rod 10, the flow channel 7 and the neck ring mold 1, the top end of the core rod 10 is rotatably connected with the machine body 2, a plurality of uniformly distributed shifting plates 6 are fixedly connected to the outer side wall of the core rod 10 located in the stirring chamber 5.
Adopt above-mentioned scheme, the feed inlet communicates with the discharge gate of extruder 3 to the feed inlet faces and dials board 6, and when the material stream that comes out from extruder 3 lets in stirring chamber 5 in, drives plug 10 and rotates, dials board 6 simultaneously and homogenizes the material stream, makes the material stream can get into runner 7 uniformly, and can not flow by the feeding side of being partial to.
The outer side wall of the core rod 10 in the runner 7 is fixedly connected with three slide bars 8 which are uniformly distributed, one ends of the three slide bars 8 are all in sliding connection with the inner wall of the runner 7, the part of the core rod 10 in the neck ring die 1 is fixedly sleeved with a spiral sleeve 9, and a gap is arranged between the spiral sleeve 9 and the inner wall of the neck ring die 1.
By adopting the scheme, the tail end of the sliding rod 8 slides on the flow channel 7 in the rotating process of the core rod 10, the core rod 10 is supported, the core rod 10 is prevented from inclining under the action of material flow, the sliding rod 8 can be cut off in the rotating process and further the material flow is stirred uniformly, and due to the property of the material flow in the melting state, after the extrusion effect of the spiral sleeve 9, the cut-off traces on the material flow can be eliminated and are uniformly distributed in the neck ring 1 and then flow out of the neck ring 1.
An air inlet is formed in the axis of the mandrel 10, a rotary joint 4 is fixedly connected to the top of the machine body 2, the air inlet is communicated with the rotary joint 4, and the other end of the rotary joint 4 is communicated with an air pump, so that the mandrel 10 can still ventilate while rotating.
The working principle is as follows: when the extrusion die is used, the material flow is extruded into the stirring cavity 5 by the extruder 3, the material flow pushes the stirring plate 6 to drive the core rod 10 to rotate when flowing, meanwhile, the stirring plate 6 is used for stirring the material flow uniformly, so that the material flow can uniformly enter the flow channel 7 and cannot flow towards the feeding side, the tail end of the sliding rod 8 slides on the flow channel 7 in the rotating process of the core rod 10, the effect of supporting the core rod 10 is achieved, the core rod 10 is prevented from inclining under the effect of the material flow, the sliding rod 8 can be scratched in the rotating process and can be further stirred uniformly, due to the property of the melting state of the material flow, after the extrusion effect of the spiral sleeve 9, the scratches on the material flow can be eliminated, and the scratches are uniformly distributed in the neck die 1 and then flow out of the neck die.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention.
