As Fig. 1 and shown in Figure 2, a kind of die device 4 of producing plastic containers is provided in a kind of embodiment of the present utility model, this die device 4 comprises the first symmetrical mold half 41 and second mold half 43, first mold half 41 and second mold half 43 are respectively equipped with Die Box 45, Die Box 45 inboards are provided with one or a plurality of die cavities of being arranged side by side, wherein each die cavity includes two sub-die cavities 42 arranging along axis direction, and Die Box 45 is provided with the separation portion 44 that two sub-die cavities 42 are separated.Each subtype chamber 42 has and the corresponding inner-cavity structure of the external structure of prepared plastic containers in the utility model.When tubular parison 23 is put between first mold half and second mold half, merge first mold half 41 and second mold half 43, tubular parison 23 is split into two sub-parisons that are separately positioned in two sub-die cavities 42 this moment, is linked to each other by separated 44 wire parison that has flattened between these two sub-parisons.After two mold halfs merge, be arranged on the certain space that has between two separation portions on two symmetrical Die Boxes 45, this space is not more than 2 times of thickness of tubular parison 23 tube walls, to its objective is in order guaranteeing and to accompany between two mold halfs under the situation of tubular parison, still can combine closely, and make two sub-die cavity 23 each self sealss.
In a kind of preferably embodiment of the present utility model, two sub-die cavities 42 are configured to respectively to extend along two rightabouts of axis in the same die cavity, form semi-circular opening at the outer surface of Die Box 45.When first mold half 41 and 43 merging of second mold half, two semi-circular openings of Die Box 45 the same sides of two mutual minute surface symmetries are formed an annular opening, in order to feed gas, make the parison bulging in the subtype chamber 42 and are adjacent to die cavity chamber wall.Certainly the equipment that is used to produce mould of plastics provided by the utility model also can be the parison plastotype by with the parison vacuum pumping.In a kind of specific embodiment of the utility model, die device 4 also comprises parison holder 47 and Sealing formboard 46, and parison holder 47 is symmetrical two groups, is separately positioned on the both sides that Die Box 45 has opening; Sealing formboard 46 is symmetrical two groups, is connected movably between Die Box 45 and each the parison holder 47.So be made as two sub-die cavities that convenience is positioned on the same axis extended line and carried out the blow molding process processing simultaneously.
As Fig. 3 and Fig. 4 while, the utility model also provides a kind of equipment of producing plastic containers, in a kind of concrete embodiment of the present utility model, the equipment of this production plastic containers comprises: support body 1, extrusion device 2, blowing device 3, die device 4, cutting member 5 and die drive unit (not shown).Die device 4 is arranged on the support body 1 movably, and on support body 1, have first fixed bit and second fixed bit, extrusion device 2 is fixedly mounted on the support body 1, be arranged on the upside of die device 4 first fixed bits, extrusion device 2 is provided with parison handpiece 21 near a side of die device, is used to extrude tubular parison 23.Blowing device 3 is fixedly mounted on the support body 1, is arranged on the upside of die device 4 second fixed bits, and wherein die device 4 has used the die device that is used to produce plastic containers provided by the utility model.And in order to cooperate this die device that is used to produce plastic containers to change the structure of blowing device 3, blowing device 3 is set to comprise two groups of blow nozzle groups 31 that can move towards die device, two groups of blow nozzle groups 31 are separately positioned on the both sides of Die Box 45, and are arranged on that die cavity extends axially on the direction in the Die Box.So just, can finish blowing step simultaneously to the subtype base in two sub-die cavities in the die device 4.
As Fig. 5 and shown in Figure 6, for a kind of environment of producing aseptic volumetric standard that more meets can be provided, in a kind of concrete embodiment of the present utility model, blowing device 3 also is provided with aseptic cover 33, blow nozzle group 31 is arranged in the aseptic cover 33, and blow nozzle group 31 can penetrate aseptic cover and matches with die device 4.So design, be for an aseptic external environment condition is provided to blow nozzle group 31, blow nozzle is used for being used with die device, it directly is inserted into the inside of parison, in the equipment of the utility model production plastic containers,, guaranteed the sterile production process of plastic containers better for the blow nozzle group provides a gnotobasis.
In a kind of preferably embodiment of the present utility model, aseptic cover 33 is provided with air intake passage 35, and this air intake passage 35 is used to feed aseptic gas.In aseptic cover 33, constantly feed aseptic gas, can make extraneous air can't enter aseptic cover 33, so just can guarantee the gnotobasis that blow nozzle stores better.More preferably, aseptic cover 33 is provided with a through hole 37 near a side of die device, and blow nozzle 31 passes from through hole 37.The area of the cross section of aseptic cover 33 is greater than the area of the cross section of die device 4, and the area of through hole 37 is less than the area of the cross section of die device 4.As shown in Figure 3 and Figure 4, when blowing device and die device are used, gas in the aseptic cover overflows from through hole 37, because the area of through hole 37 is less than the area of the cross section of die device 4, aseptic gas can only outwards circulate from the slit between aseptic cover and the die device, simultaneously, because the area of the cross section of aseptic cover 33 is greater than the area of the cross section of die device 4, this just makes the air that is overflowed walk towards the effluent away from blowing device 3, and this has just guaranteed the sterile working in the plastic containers forming process.Container by the equipment making of production plastic containers provided by the utility model is met more be used for the aseptic standard of pharmaceuticals industry.
It is to be noted; thisly in blowing device, increase aseptic cover 33; and feed the method for aseptic gas in the inside of aseptic cover 33; not only can be used in the equipment of production plastic containers provided by the utility model; simultaneously; also can use in the various device for preparing plastic containers in the prior art; protection domain of the present utility model not only for equipment provided by the utility model, the equipment of the structure of aseptic cover and method all belongs in the protection domain of the present utility model in any use the utility model.
The method of operating of equipment that plastic containers are provided in the method for operating of the equipment of the production plastic containers that provided in the utility model and the prior art is identical, according to the difference of selected raw material, regulates the various parameters of machine operation in the production process.The die device of production plastic containers provided by the utility model is not increasing plastic tube-shape parison quantity, on the basis of the length of tubular parison, has increased the quantity of one-shot forming ground container when only increasing moulding, has improved production efficiency greatly.Simultaneously, the equipment of production plastic containers provided by the utility model, not only improved production efficiency, simultaneously because the aseptic blowing position that covers on has covered whole mould, prevent the possibility that bacterium and other particulate enter the blowing opening, therefore be specially adapted to the production of the aseptic volumetric standard of pharmaceuticals industry.
Be preferred embodiment of the present utility model only below, be not limited to the utility model, for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
