Description
Technical field
The technical field of duct products production application is the utility model is related to, more particularly, to a kind of novel PVC double-walled
Bellow mold.
Background technology
Double-wall PVC corrugated pipe products are double-walled composite construction, use when traditional dies produce tubing and are set in the middle part of die body
Put through type spreader and carry out ectonexine shunting, because runner diminishes suddenly in the middle part of mould, pressure sharply increases, and is limited by space,
Shunting is difficult to balance, and the product sheet is as thin wall product, easy imitation frosted glass during formed product, is easily sent out after formed product
Yellow, cracking.
Utility model content
The utility model is to overcome at least one defect described in above-mentioned prior art, there is provided a kind of novel PVC double-walled ripple
Line pipe mold, by the structure optimization on mould, improve production stability.
The technical solution of the utility model is：A kind of novel PVC double-wall corrugated pipe mold, wherein, including die holder, located at mould
Center spreader and double-deck diversion cone in seat, in addition to double bracket spreader, double bracket spreader connect outer layer contraction respectively
Body, outer layer core rod, internal layer shrink core and central reduction core, the outer layer melt operation that outer layer liquid shrinkable is formed with outer layer core rod are logical
Road, the internal layer melt operation passage that internal layer shrink core is formed with central reduction core；
Also include outer layer mouth mold, internal layer mouth mold and interior outer core rod, the outer layer sizing that outer layer mouth mold is formed with outer layer core rod is logical
Road, the internal layer sizing passage that internal layer mouth mold is formed with interior outer core rod.
Further, Double-wall PVC bellow mold is additionally provided with the adjusting screw that displacement is carried out for adjusting outer layer mouth mold.
Heat abstractor is provided with the middle part of Double-wall PVC bellow mold, air admission hole introduces cold air by radiating.
Double-wall PVC bellow mold also includes pressing plate, makes pressing plate fixed outer layer mouth mold and die holder by pressing plate fixing screws.
Double-wall PVC bellow mold also includes outer layer liquid shrinkable fixing screws.
Compared with prior art, beneficial effect is：Compact-sized, production operation is more simple；Improved flow passage structure is set
Meter, production imitation frosted glass is reduced, product jaundice, uses problem of Cracking；Same type PVC pipeline production is suitable for, it is useless to reduce production
Product rate.Mould uses double bracket flow dividing structure, realizes ectonexine melt loading sharing, reduces imitation frosted glass, turns to be yellow, opens after formed product
Split.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent；It is attached in order to more preferably illustrate the present embodiment
Scheme some parts to have omission, zoom in or out, do not represent the size of actual product；To those skilled in the art,
Some known features and its explanation may be omitted and will be understood by accompanying drawing.Being given for example only property of position relationship described in accompanying drawing
Explanation, it is impossible to be interpreted as the limitation to this patent.
1st, the mould mainly by（Fig. 1）Formed shown in structure.
2nd, melt enters mould by the feeding mouth of die holder 1, and makees by the water conservancy diversion of center spreader 2 and double-deck diversion cone 3
Two stock material streams are divided into by one stream with by melt.
3rd, it is divided into two strands of melt, by leading into the middle part of mould for double bracket spreader 4, double bracket spreader 4 divides
Lian Jie not outer layer liquid shrinkable 5, outer layer core rod 6, internal layer shrink core 7 and central reduction core 8.Outer layer liquid shrinkable 5 and the shape of outer layer core rod 6
Into outer layer melt run passage, passage is become narrow gradually by width, progressively that melt compression is closely knit, it is ensured that outer layer melt interior molecules
Thoroughly fusion；The internal layer melt operation passage that internal layer shrink core 7 is formed with central reduction core 8, passage are become narrow gradually by width, progressively
It is melt compression is closely knit, it is ensured that internal layer melt interior molecules thoroughly merge；
4th, by the melt of the ectonexine progressively compressed, continue to run forward in die body, to meet the chi of sizing cooling
Very little requirement, melt need sizing is further further compressed by mouth mold, core rod profiled section, change melt wall thickness size and
Appearance and size.Wherein, the outer layer sizing passage that outer layer mouth mold 9 is formed with outer layer core rod 6, by melt progressively by thick thinning, external diameter
Size from large to small, forms a longitudinal stretching, strengthens product strength；The internal layer that internal layer mouth mold 11 is formed with interior outer core rod 12 is determined
Type passage, by melt progressively by thick thinning, outside dimension from large to small, forms a longitudinal stretching, strengthens product strength.
5th, it is product uniform wall thickness when ensureing production, adjusting screw 14 is provided with mould, when there is deviation in wall thickness,
Adjustment outer layer mouth mold 9 can be acted on by adjusting screw 14 and carries out displacement, until size uniform；To ensure that product can cool down rapidly,
Heat abstractor is provided with the middle part of mould, air admission hole 16 introduces cold air by radiating, and is taken away by cold air and is present in mould inside heat
Amount prevents the excessively thermally-induced imitation frosted glass of central reduction core 8.Double-wall PVC bellow mold also includes pressing plate 10, passes through pressing plate fixing screws
13 make the fixed outer layer mouth mold 9 of pressing plate 10 and die holder 1.Double-wall PVC bellow mold also includes outer layer liquid shrinkable fixing screws 15.
Obviously, above-described embodiment of the present utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.There is no need and unable to give all embodiments
It is exhaustive.All made within spirit of the present utility model and principle all any modification, equivalent and improvement etc., should be included in
Within the protection domain of the utility model claims.
