Description
Technical field
The present invention relates to the dry-type stock mold shaped to plastic extrusion parison, specifically one kind can eliminate section bar
The dry-type stock mold of surface merging trace.
Background technology
Dry-type stock mold is the equipment for shaping to the parison squeezed out by die head.Usual dry-type stock mold by it is upper,
The several piece template composition of lower superposition.As disclosed in CN201249520Y dry-type stock mold by the above, the lower lid and positioned at it is intermediate it is upper,
Lower template forms, and cavity is respectively provided in upper and lower template.Since the rigging error of stock mould and inevitable repetition are opened
Open, thus upper and lower template at die joint there are gap, parison when by stock mould since suction function is close to cavity wall,
So that preform surface inevitably is left a trace at die joint splices trace.Especially for foamed profile, due to depositing
In larger fillet, Surface of profile, which generates splicing trace, can influence foamed profile presentation quality, and defect rate is caused to improve, and then significantly
Increase production cost.
The content of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of dry types for eliminating Surface of profile splicing trace to determine
Pattern will not make Surface of profile generate splicing trace, can improve section material appearance quality.
To achieve the above object, present invention employs following technical schemes：It is fixed at least one set of fixed on platen including platen
Type component, the styling components are longitudinally arranged and passed through the template that bolt is connected by several and formed, be provided among every piece of template with
The cavity of Parison Shape cooperation, every piece of template are internally provided with the cooling water channel around cavity arrangement, and cooling water channel both ends, which have, to be led to
The water-in and water-out passage of template outer wall, the outer end of water-in and water-out passage are equipped with water-in and water-out interface；Between the end face of adjacent two pieces of templates
The first gas chamber of cavity arrangement and the air drain of the first gas chamber of connection and cavity are provided around, positioned at intermediate each template first
The upper and lower of gas chamber has interconnected upper and lower transverse air channel, is equipped between the end face of adjacent two pieces of templates by first
The upper and lower longitudinal gas channel that gas chamber is connected with upper and lower transverse air channel, positioned at the outer wall of intermediate one or a few blocks template be equipped with
The upper and lower main airway that upper and lower transverse air channel communicates, template outer wall are equipped with the upper suction interface communicated with upper main airway.
Further, platen upper end sets the second gas chamber, the lower main airway of styling components and the second gas chamber phase on platen
Logical, lower pumping interface is equipped on platen side wall.
Preferably, the styling components have three to four groups, and every group of styling components include at least four to five pieces of templates, and every group is determined
A pair of upper and lower suction interface is set on type component, and each group styling components are fixed independently to platen along parison moving direction precedence
On.
The beneficial effects of the present invention are：Longitudinally disposed by the way that the template of styling components is changed to, cavity surrounding continuously becomes
Change without there is gap so that parison and sizing model cavity into cover half type come into full contact with friction, thus can eliminate foaming
Surface merging trace phenomenon improves section bar particularly foamed profile presentation quality, and since Surface of profile is not in splicing trace,
So that section bar uniform wall thickness, can improve section bar intensity.

Specific embodiment
Below in conjunction with the accompanying drawings, the technical solution in the embodiment of the present invention is clearly and completely described.
The present invention includes platen 1, and at least one set of styling components 2 are fixed on platen 1, and styling components 2 have three to four in this example
Group, each group styling components 2 are fixed independently to along 8 moving direction of parison on platen 1 successively, and every group of styling components 2 are by five pieces of moulds
Plate 21~25 forms, and template 21~25 is longitudinally arranged and passes through bolt 6 and is connected.In order to ensure the cavity of each styling components template height
Degree is consistent, and 1 both sides of platen are equipped with the fixture block 5 of fixed styling components 2, and each template lower end is connected by positioning square key 11 with platen 1.
The cavity 7 with 8 form fit of parison, every piece of template are provided among each piece of template 21~25 of every group of styling components 2
21~25 are internally provided with the cooling water channel 3 arranged around cavity 7.3 both ends of cooling water channel have lead to 21~25 outer wall of template into,
Exhalant canal 31,32, the outer end of water-in and water-out passage 31,32 are equipped with water-in and water-out interface 33,34.The cooling water channel 3 can be by template
Groove is processed into 21~25 1 side end faces, then is sealed groove surfaces with plug 35.Water-in and water-out passage 31,32 can be by mould
Plate side-wall hole is molded.
Be provided around between the end face of adjacent two pieces of templates the arrangement of cavity 7 the first gas chamber 4 and the first gas chamber 4 of connection with
The air drain 49 of cavity 7, positioned at intermediate each template 22~24 the upper and lower of the first gas chamber 4 have it is interconnected it is upper,
Lower transverse air channel 44,47 is equipped between the end face of adjacent two pieces of templates and connects the first gas chamber 4 with upper and lower transverse air channel 44,47
Upper and lower longitudinal gas channel 43,46, be respectively equipped in intermediate template 23 communicated with upper and lower transverse air channel 44,47 it is upper,
Lower main airway 45,48, upper and lower main airway are opened on the upper and lower end of template 23 respectively, and 23 upper end of template is on main airway outlet is set
Equipped with upper suction interface 41,1 upper end of platen sets the second gas chamber 12, lower longitudinal gas channel 47 and second on platen 1 of template 23
Gas chamber 12 communicates, equipped with the lower pumping interface 42 communicated with the second gas chamber 12 on platen side wall.
To prevent water, gas from interfering, the first gas chamber 4, air drain 49, upper transverse air channel 44 and lower transverse air channel 47 add respectively
Work is on above-mentioned template 21~25 end face opposite with 35 place end face of plug.
The present invention can set one group of styling components 2, and the template number of styling components accordingly increases, to reach sizing effect
Fruit.In view of being evacuated effect, several upper and lower main gas being used for the pumping of the first gas chamber 4 can be set in intermediate template
Road 45,48, and increase the upper and lower suction interface 41,42 of respective numbers.
Operation principle is as follows：When parison 8 passes through styling components 2 in the direction of the arrow, vacuum extractor by being evacuated above and below
41,42 pairs of styling components 2 of interface vacuumize, the air in styling components 2 respectively through upper main airway 45, upper transverse air channel 43, on
Second gas chamber 12 of longitudinal gas channel 44 and platen 1, lower main airway 48, lower transverse air channel 47, lower longitudinal gas channel 46 are to the first gas chamber
4 vacuumize, and are adsorbed parison 8 on 7 inner wall of cavity by air drain 49.Meanwhile water supply installation by cooling water from every piece of template
Water inlet interface 33 conveys cooling water into template, through intake tunnel 31, cooling water channel 3, exhalant canal 32, then by water outlet mouthpiece 34
Outflow, so as to which the heat in template be taken away.
