Abstract
The utility model relates to a PET bottle blowing mould, and discloses a one-blank double-cavity bottom-to-bottom squeeze blowing mould. The counter-bottom squeeze blowing mould comprises a bottle-shape mould (1), wherein the inner cavity of the bottle-shape mould (1) can form an upper and a lower mould cavities (3, 4), the upper mould cavity (3) is communicated with the lower mould cavity (4), the upper mould cavity (3) consists of a bottle body mould cavity section (31) and a bottle bottom mould cavity section (32), the lower mould cavity (4) consists of a bottle body mould cavity section (41) and a bottle bottom mould cavity section (42), and the bottle bottom mould cavity section (32) of the upper mould cavity (3) and the bottle bottom mould cavity section (42) of the lower mould cavity (4) are arranged bottom to bottom. The PET bottle blowing mould can realize the effect of blowing two bottles in one tube blank, and can double the yield through changing the structure of the mould under the condition of not changing original production equipment. The structure of the mould is provided with two mould cavities with independent blowing holes, after the mould is closed, the pipe blank can simultaneously enter two mould cavities, and compressed air are blown through independent blowing systems to shape products.
Description
Technical field
The utility model relates to the PET bottle blowing mould, relates in particular at the bottom of the embryo two-chamber end extrusion blow mould.
Background technology
At present, use the field in the production of bottle blowing mould, what traditional bottle type extrusion blow mould adopted all is the structure in an embryo list chamber, i.e. bottle type of a pipe embryo blowing.Such as, in the existing disclosed patent documentation, application number is 200620039118.6, the applying date is on January 20th, 2006, Granted publication number is CN2882971, the day for announcing is on March 28th, 2007, the patentee discloses a kind of extruding and blowing machine mouth mould for the Chinese utility model patent of Zheng Ting, it comprises an installation pressing plate, go up the collar extension mould for one, a following collar extension mould, an internal orifice mould, last collar extension mould is pressed on the urceolus of die head die cavity with the installation pressing plate, the internal orifice mould is by on the plug that is threadedly connected to the die head die cavity, following collar extension mould is connected with last collar extension mould with bolt, on, following collar extension mould and internal orifice mould have been formed the extrusion forming cavity.Though adopt this mouthful of mould, can enlarge a mouthful mould and extrude diameter range, thereby enlarge the production specification scope that plastics are extruded bottle blowing machinery; When products of different specifications is needed the replacement port mould,, and do not need to remove and install pressing plate and go up the collar extension mould as long as change collar extension mould, internal orifice mould down.But the bottle output that adopts such mold mechanism to produce is limited, if the change by mould structure doubles the quantity of output under the situation that does not change original production equipment, then can enhance productivity greatly and output.
Summary of the invention
The utility model at exist in the existing bottle blowing mould because of the self structure reason causes the bottle output of production limited, can not satisfy the shortcoming that extensive high efficiency production requires and improve, provide a kind of rational in infrastructure, double the quantity of output, can enhance productivity greatly in the change by mould structure under the situation that does not change original production equipment and a kind of embryo two-chamber of output at the bottom of to end extrusion blow mould.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
At the bottom of the one embryo two-chamber to end extrusion blow mould, comprise a bottle pattern, the inner chamber of described bottle pattern forms two die cavitys up and down, upper cavity is connected with lower mode cavity, upper cavity comprises body die cavity section and bottom mould chamber section, lower mode cavity comprises body die cavity section and bottom mould chamber section, at the bottom of the bottom mould chamber section of the bottom mould chamber section of upper cavity and lower mode cavity the end is provided with.Adopt the structure that the bottle end of upper cavity and lower mode cavity is oppositely arranged, can realize upper cavity and lower mode cavity respectively extrusion blow go out bottle product, feasible bottle output is doubled; And the structure that upper cavity is connected with lower mode cavity can more help circulation of air, makes plastics to be become bottle product unanimous between the higher and lower levels by extrusion blow equably.
As preferably, the inflatable mouth of described upper cavity is provided with up, and the inflatable mouth of lower mode cavity is provided with down, and two die cavitys are respectively equipped with independently inflatable mouth up and down, and behind the mould matched moulds, the pipe embryo enters two die cavitys up and down simultaneously, the beginning extrusion blow.
At the bottom of the upper cavity bottle and the junction at the bottom of the lower mode cavity bottle forms block.After the moulding of pipe embryo extrusion blow bottle, form block at the bottom of the upper cavity bottle and the junction at the bottom of the lower mode cavity bottle, this block is cut off as waste material at last, makes that two bottles are split up into two independently bottle products up and down.
The utility model is owing to adopted above technical scheme, has significant technique effect: can reach the effect that a pipe embryo is once blown two bottle types, and the structure that upper cavity is connected with lower mode cavity can more help circulation of air, make plastics to be become bottle product unanimous between the higher and lower levels, under the situation that does not change original production equipment, double the quantity of output by changing mould structure by extrusion blow equably.In this mould structure, two die cavitys have independently inflatable mouth up and down, behind the mould matched moulds, the pipe embryo enter two die cavitys simultaneously, compressed air through separately independently scavenger system with the product blow molding.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2 and embodiment the utility model is described in further detail:
At the bottom of the embodiment one embryo two-chamber to end extrusion blow mould, comprise bottle pattern 1, the inner chamber of described bottle pattern 1 forms upper cavity 3 and lower mode cavity 4, upper cavity 3 is connected with lower mode cavity 4, upper cavity 3 comprises body die cavity section 31 and bottom mould chamber section 32, and lower mode cavity 4 comprises body die cavity section 41 and bottom mould chamber section 42, and the bottom mould chamber section 32 of upper cavity 3 was provided with the end of with 42 ends of bottom mould chamber section of lower mode cavity 4, the inflatable mouth 30 of upper cavity 3 is provided with up, and the inflatable mouth 30 of lower mode cavity 4 is provided with down.
Adopt the structure that the bottle end of upper cavity 3 and lower mode cavity 4 is oppositely arranged, can realize upper cavity 3 and lower mode cavity 4 respectively extrusion blow go out bottle product, make bottle output be doubled.Upper cavity 3 and lower mode cavity 4 are respectively equipped with independently inflatable mouth 30 and blow afloat mouthfuls 40, behind the mould matched moulds, the pipe embryo enters upper cavity 3 and lower mode cavity 4 simultaneously, the beginning extrusion blow, at last at the bottom of 3 bottles of upper cavities, form block 2 with junction at the bottom of 4 bottles of the lower mode cavities, this block 2 is cut off as waste material at last, makes that two bottles are split up into two independently bottle products up and down.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
