Abstract
The invention discloses a method for continuously manufacturing plastic box bodies, and the method comprises the following steps: adding an opening-closing box bottom forming device at the machine head of a tube extruding machine; when an outer mold and an inner mold in the box-bottom forming device are folded, injecting plasticized plastics extruded by the tube extruding machine into the molds in the box-bottom forming device; forming the bottom of a plastic packaging box at the end of an extruded tube; opening the outer mold of the box-bottom forming device and enabling the tube extruding machine to carry out extruding continuously so as to form the side wall of the packaging box; and when the length of the extruded side wall reaches the required size, starting a cut-off device so as to cut off the side wall. The invention also discloses a device for continuously manufacturing plastic box bodies. By using the method and device disclosed by the invention, the required time (more than ten seconds) for manufacturing each plastic box body in an injection molding mode can be shortened by more than a half without wasting the materials of injection molding nozzles, thereby achieving the effects of improving the production efficiency, saving materials and reducing the energy consumption.
Description
Technical field
The present invention relates to plastic box body manufacture method and device, the method and the device of heavy wall plastic box body made in especially a kind of injection moulding continuously.
Background technology
In the prior art, the production of heavy wall plastic box body nearly all is to adopt to use the mold injection method on injection machine.Because this method need experience matched moulds, injection moulding, pressurize, moulding, cooling, branch mould several steps, production time is longer, in injection moulding dwell time section, need outside the plastic raw materials of injection machine injecting plasticizing in mold cavity, all the other times can only be waited for, therefore efficient is lower, and energy consumption is bigger.
Summary of the invention
The purpose of this invention is to provide a kind of injection moulding continuously and make the method and the device of heavy wall plastic box body, improve the operating efficiency of equipment, thereby reach the effect that shortens the production time, cuts down the consumption of energy.
A kind of plastic box body method for continuous production, it is characterized in that: but at the bottom of the box that increases folding on the head of pipe extruder shaped device, when the external mold in the shaped device at the bottom of the box and internal mold are closing up under the state, the plasticizing plastics that extruder is extruded are injected into the mould in the shaped device at the bottom of the box, form the bottom of plastic casing in the end of institute's extruding pipe material, the external mold of shaped device at the bottom of the box is opened, extruder can continue to extrude, form the sidewall of packing box, when the length of extruding sidewall reached the requirement size, shearing device started its cut-out.At the bottom of the described box shaped device also comprise the internal mold that becomes one with the head core, the external mold opened that flexibly connects with machine head port mould and be positioned at mouthful shearing device of mould outer end.In shaped device at the bottom of the described box, also comprise heating arrangements and cooling and shaping mechanism.The vacuum-pumping pipeline that is communicated with inside and outside the die cavity is arranged in shaped device at the bottom of the described box.Water circulating pump and heat abstractor that described typing cooling body comprises the cooling-water duct that places external mold inside, connects by connecting pipe.Described shearing device comprises box mouth mould and cuts off cutting die.
Description of drawings
The present invention will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the injection phase schematic diagram.
Fig. 2 extrudes the moulding of back box mouth and cuts off schematic diagram.
Wherein: 1-head connector, 2-divide shaping mould at the bottom of flow cone, 3-core support, 4-die body, 5-core, 6-mouth mould, the 7-box, 8-hinge, 9-box mouth shaping mould and cut off cutting die, 10-cooling fluid pipeline, 11-heating rod, 12-vavuum pump interface, 13-workpiece---plastic box body.
The specific embodiment
Disclosed all features in this specification, or the step in disclosed all methods or the process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
Provided one embodiment of the present of invention among Fig. 1, Fig. 2:
A kind of plastic box body method for continuous production, it is characterized in that: but at the bottom of the box that increases a folding on the head of pipe extruder shaped device, when the external mold in the shaped device at the bottom of the box and internal mold are closing up under the state, the plasticizing plastics that extruder is extruded are injected into the mould in the shaped device at the bottom of the box, form the bottom of plastic packing box in the end of institute's extruding pipe material, the external mold of shaped device at the bottom of the box is opened, extruder can continue to extrude, form the sidewall of packing box, when the length of extruding sidewall reached the requirement size, shearing device started its cut-out.
A kind of plastic box body apparatus for continously production: comprise the pipe extruder head that is made of die body 4, core 5, mouthful mould 6, described core 5 is fixedlyed connected with die body 4 by core support 3; But this device also comprises shaping mould 7 and moulding of box mouth and shearing device 9 at the bottom of the box of the folding that flexibly connects with machine head port mould 6, and shaping mould 7 is connected with die body 4 by hinge 8 at the bottom of the box.In shaped device at the bottom of the described box, also comprise heating rod 11 and the cooling fluid pipeline 10 that plays the cooling and shaping effect.The vacuum-pumping pipeline that is communicated with inside and outside the die cavity is arranged in shaped device at the bottom of the described box, be connected with vavuum pump by vavuum pump interface 12.
Described die body 4 is connected with extruder by head connector 1, and the plastics of plasticizing enter die body, enter shunting zone through minute flow cone 2, enters shaping area after entering the compressional zone then.
The present invention is divided into injection moulding, moulding pressurize, extrudes and cut off three steps.Injection phase wherein, heating rod 11 heats for head core 5, has good flowability to guarantee plastics, and simultaneously, vavuum pump starts, and the plastics of plasticizing flow fast, make moulding at the bottom of the box; And then enter moulding pressurize step, heating rod 11 stops heating, and cooling fluid enters cooling fluid pipeline 10, makes in type box body 13 cooling cooling forming rapidly; Open shaping mould 7 at the bottom of the box then, extruder continues to extrude, and makes molded box body 13 extending port moulds 6 to specific length, and box mouth shaping mould and cut off cutting die 9 and start downcuts box body 13.
Because the shape of cross section of pipe extruder institute extruding pipe material depends on that therefore the cross section of heavy wall plastic box body of the present invention can be multiple shapes such as circle, rectangle, polygon to the designed shape of shaping mould at the bottom of core, mouthful mould and the box.
For further increasing work efficiency, every extruder can be installed plural device of the present invention, utilizes the alternation of melt transfer valve.
The present invention can produce former injection moulding mode the required tens second time of every plastic box body and shorten over halfly, and does not have the waste of injection hole material, reached enhance productivity, economical with materials, the good result that cuts down the consumption of energy.
The present invention is not limited to the aforesaid specific embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
