Abstract
The present invention discloses a double-wall corrugated pipe mold, which comprises an outer mold assembly for forming the outer wall of a double-wall pipe and an inner mold assembly for forming the inner wall of the double-wall pipe, wherein the outer mold assembly comprises an outer wall die and an outer mold core mold, the inner mold assembly comprises an inner wall die and an inner wall core mold, the outer wall die, the outer wall core mold, the inner wall die and the inner wall core mold are sequentially arranged in the circumferential direction from outside to inside, an outer wall material outlet is formed between the outer wall die and the end portion of the outer wall core mold, an inner wall material outlet is formed between the inner wall die and the end portion of the inner wall core mold, and a distance between the outer wall die and the inner wall die is 5-10 mm. With the design scheme, the distance between the outer wall die and the inner wall die is reduced by dozens of times of the original distance, such that the outer wall layer and the inner wall layer can substantially and concurrently enter the cooling water jacket so as to avoid temperature difference of the combination surface, make the combination position adhesion firm, especially provide excellent effects for recovery and recycling raw materials, make products be adapt to hot weathers in summer, and prolong the service life.
Description
Technical field
the present invention relates to a kind of double-wall corrugated pipe mold.
Background technology
in double-wall corrugated pipe mold in conventional art, mouthful mould modular construction as shown in Figure 1, due to the distance H 1 between outer wall mouth mould and inwall mouth mould larger (generally at 200～300mm), the discharging of inwall mouth mould is introduced into the outer surface of cooling jacket, and then the discharging of outer wall mouth mould enters cooling jacket and inner wall layer touch again.Because the time difference makes the faying face of outer wall layer and inner wall layer produce temperature difference, double-wall pipe goods be just not easy in double-deck junction bonding firmly, particularly for the raw material of recycling, due to poor-performing own, more difficult bonding live.Especially be summer for the occasion that is widely used in the market recovered material and does double-wall pipe, inwall seals the air pressure producing, and more easily makes inner wall layer and outer wall layer depart from, and causes seriously reduce service life.
Summary of the invention
for the technical deficiency of above-mentioned existence, the object of this invention is to provide a kind of double-wall corrugated pipe mold, distance between outer wall mouth mould wherein and inwall mouth mould is significantly smaller than in original technology, make outer wall layer and inner wall layer almost enter cooling jacket simultaneously, avoid the temperature difference of the two faying face, efficiently solved the two-layer problem being separated.
for solving the problems of the technologies described above, the present invention adopts following technical scheme:
a kind of double-wall corrugated pipe mold, comprise the outer membrane module of the outer wall that is used to form double-wall pipe, be used to form the interior membrane module of the inwall of double-wall pipe, described outer membrane module comprises outer wall mouth mould, outer wall core, described interior membrane module comprises inwall mouth mould, inwall core, described outer wall mouth mould, described outer wall core, described inwall mouth mould, described inwall core is circumferentially ecto-entad setting successively, between the end of described outer wall mouth mould and described outer wall core, form outer wall discharging opening, between the end of described inwall mouth mould and described inwall core, form inwall discharging opening, distance between described outer wall mouth mould and described inwall mouth mould is 5～10mm.
preferably, described outer wall mouth mould is fixedly connected on an outer wall and puts outward.
preferably, described outer wall core is fixedly connected in an outer wall and is put by an adapter sleeve.
preferably, described inwall mouth mould is fixedly connected on an inwall by a spacer shell and puts outward.
preferably, described inwall core is fixedly connected in an inwall and puts.
preferably, described spacer shell closes in described adapter sleeve, has the multiple projections that are uniformly distributed circumferentially on the outer wall of described spacer shell.
preferably, on described inwall core, be provided with for regulating the uniform governor motion of interior wall thickness, described governor motion comprises along being circumferentially evenly opened in multiple tapped through holes on described inwall core, can being telescopically spun on the bolt in described tapped through hole, each described tapped through hole radially extends, and axle center, the other end of the inwall core described in the head points of each described bolt are pushed against on the inwall of described spacer shell.
preferably, described outer wall core and described inwall mouth mould are formed in one, and its inside has the internal thread, the side that are connected with described spacer shell and has the step surface fastening with described adapter sleeve.
beneficial effect of the present invention is: by the Structure Improvement Design to outer wall core and inwall mouth mould, the distance furthering between outer wall mouth mould and inwall mouth mould, on numerical value, be about 1/tens of original distance, outer wall layer and inner wall layer can almost be entered on cooling jacket simultaneously, and then avoid the temperature difference of the two faying face, make double-wall pipe goods bonding firm in double-deck junction, particularly for the raw material of recycling, effect is better obviously, make goods more can adapt to the hot weather in summer, effectively increase the service life.
