Abstract
The utility model discloses a machine head module of a novel plastic extruder. The machine head module comprises a machine head body which is provided with a feeding channel and a material storage cylinder which is connected with the extruder, the feeding channel of the machine head body and the extrusion direction of a parison of the extruder are at right angle, and an extrusion port is formed in the bottom of the material storage cylinder and is connected with a mold. The machine head module has the advantages that a parison die head enables melt to be stored and can be used for uniformly providing melt, so that the reduction of product quality caused by excessive or too little melt is avoided, and the machine head module is simple in structure, easy in control on melt flow, simple in operation and convenient to use, and can be used for improving the product quality and the working efficiency.
Description
Technical field
The utility model relates to a kind of extruder, and a kind of Novel plastic extrusion machine head module specifically belongs to the extruder field.
Background technology
Blowing also claims hollow blow molding, is a kind of plastic working method.Thermoplastic resin (or is heated to soft state) while hot through the tubular plastic parison of extruding or injection moulding obtains, and is placed in split cavity, pass into immediately compressed air after mold closing in parison, make the plastic parison inflation and be close on mould inner wall, through cooling and demolding, namely obtaining various hollow products.Make the container of hollow and thin-walled by extrusion and blow molding technique.The capacity of its container molding is little of several milliliters, and maximum can be to several ten thousand liters.The plastics that are applicable to blowing have polyethylene, polyvinyl chloride, polypropylene, polyester etc., and among gained, empty is widely used as the industrial packaging container, and food, beverage, cosmetics, medicine, Cleaning preparations, toy for children etc.Yet present hollow blow molding equipment is difficult to control for the melt of melt, and the too much or very few product quality that easily causes of melt descends, and operating efficiency is not high, and product quality is not high.
The utility model content
In order to address the above problem, the utility model has designed a kind of Novel plastic extrusion machine head module, this parison die is stored melt, can evenly provide melt, avoid the too much or very few problem that causes product quality to descend of melt, simple in structure, mobile control for melt is easy, simple to operate, easy to use, improved output and quality and operating efficiency.
The technical solution of the utility model is:
A kind of Novel plastic extrusion machine head module comprises the head body, and described head body is provided with accumulator, feeding-passage and screw rod interface;
Described accumulator is connected with extruder;
It is rectangular that the feeding-passage of described head body and extruder parison are extruded direction;
Described accumulator bottom is provided with extrusion, and is connected with mould, by extrusion with the melt extrusion in accumulator to mould, obtain extrusion plastic products.
Further, described accumulator top is provided with plunger, and plunger is connected with stepper motor, can according to how many change in elevation of melt in accumulator, and material evenly is provided.
Described head body is provided with spreader, and described spreader is fixed on described head body by die sleeve.
In addition, described spreader has throttle, and the profile of throttle is streamlined, and throttle dwindles the effective cross-section of head internal channel, increases melt pressure.
The feeding-passage of described head body is provided with the displacement-adjustable choke valve, can regulate the flow velocity of melt.
Provide plasticizing uniform melt by extruder to accumulator, be stored in accumulator according to required melt quantity of certain cycle.By plunger (or screw rod) regularly, off and on institute's storing material is all released rapidly, form large-scale parison in the accumulator system.At a high speed release tenesmus and the undergauge that material can alleviate large-scale parison, overcome parison and produce the inconsistency of the product wall thickness that sagging distortion causes due to deadweight.Extruder can be kept in continuous operation simultaneously, gets the raw materials ready for next parison, and this head can be brought into play the ability of extruder, can improve again the extruded velocity of parison, shortens molding cycle.
The utility model has the advantage of: this parison die is stored melt, melt can evenly be provided, avoided the too much or very few problem that causes product quality to descend of melt, simple in structure, mobile control for melt is easy, simple to operate, easy to use, improved output and quality and operating efficiency.
The utility model is described in further detail below in conjunction with drawings and Examples.

Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.
Embodiment 1
As shown in Figure 1, a kind of Novel plastic extrusion machine head module comprises head body 1, and described head body 1 is provided with accumulator 3 and feeding-passage;
Described accumulator 3 is connected with extruder 2;
It is rectangular that the feeding-passage of described head body 1 and extruder parison are extruded direction;
Described accumulator 3 bottoms are provided with extrusion 5, and are connected with mould 6, by extrusion 5 with the melt extrusion in accumulator 3 to mould 6, obtain extrusion plastic products; Described accumulator 3 tops are provided with plunger 4, and plunger 4 is connected with stepper motor, can according to how many change in elevation of melt in accumulator, and material evenly is provided.
It should be noted that at last: the above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps part technical characterictic wherein is equal to replacement.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.
