Description
Technical field:
The utility model relates to a kind of plastics machinery part of appliance, particularly a kind of plastic corrugated pipe molding machine machine head.
Background technology
Existing a kind of plastic corrugated pipe molding machine head mainly is made up of head die body, mouthful mould, core, ripple mould and die sleeve thereof, in therein the ripple mould and die sleeve thereof, is arranged at intervals with the water cooling chamber and the suction chamber (referring to Fig. 5) of a plurality of idle loop shapes.After molten plastic bellows blank enters the ripple mould, pipe is close to the inner surface of ripple mould and forms bellows under the swabbing action of vavuum pump, cooled off bellows body and outer surface through the water cooling chamber by the cooling water flow that water pump pumps this moment in cooling ripple mould, the inner surface of bellows then cools off by the air-flow in the bellows, and makes the bellows cooling of having finalized the design.Because a plurality of water cooling chambers and suction chamber are to be provided with at interval in the finite length of ripple mould, have only the water cooling chamber that cooling effect is just arranged, so the film-cooled heat of ripple mould are little, the cooling effect of bellows is just poor.And gas flow temperature height, flow velocity in the bellows are little, so the cooling effect of its inner surface is also not very good, so that the defective of this corrugated pipe forming machine head is exactly the typing cooling velocity of bellows is slow excessively, production efficiency is low.
The utility model content:
The technical problems to be solved in the utility model is: provide a kind of typing cooling velocity fast, the plastic corrugated pipe molding machine head that production efficiency is high is to overcome the deficiency that above-mentioned prior art exists.
The technical scheme that solves the problems of the technologies described above is: a kind of plastic corrugated pipe molding machine head, comprise head die body, mouthful mould, core, ripple mould and by water composite cooling pipe in the bellows be arranged on the moulding cooling device that the spraying suction chamber of ripple mould exterior circumferential constitutes, interior water composite cooling pipe is arranged in the pore of core and puts in the ripple mould after connecting this core along the central longitudinal of described core, front end has the center shower nozzle, its rear end is passed through core backward along pore and is entered in the head die body, outwards draws in the head die body again, and by the external high-pressure hydraulic pump of flexible pipe; The described spraying suction chamber that is arranged on ripple mould exterior circumferential is a volume greater than the volume of ripple mould and holds the empty box of this ripple mould down, front/rear end central part at this spraying suction chamber respectively has a hole that penetrates these chamber both ends of the surface, the ripple mould pass this hole and horizontal the spraying suction chamber in, on the outer wall of described spraying suction chamber, be provided with at least one pump orifice that penetrates this outer wall and outside shower nozzle.
Owing to take above technical scheme, it is fast that the plastic corrugated pipe molding machine head of the utility model has the typing cooling velocity of bellows, the beneficial effect that production efficiency is high: from the molten plastic ripple pipe of head, externally have in the ripple mould of the suction chamber of spraying, because vavuum pump is by aspirating the spraying suction chamber, make the ripple pipe be close to the ripple mould and form bellows, meanwhile, water from high-pressure hydraulic pump, bellows in whole ripple mould and the ripple mould is sprayed through center shower nozzle and each outside shower nozzle with nebulizing, make that the bellows typing in ripple mould and the ripple mould is cooled off.This type of cooling is that the integral body of ripple mould and interior bellows thereof is carried out, cooling range has comprised ripple mould and interior bellows thereof, make that cooling surface has obtained increasing to greatest extent, the center shower nozzle is adopted and is used water as the directly in type bellows of cooling of refrigerant simultaneously, it is much bigger that the heat of taking away is made refrigerant more than air-flow, and make bellows moulding cooling rapidly, therefore improved production efficiency.
Be described further below in conjunction with the technical characterictic of drawings and Examples the plastic corrugated pipe molding machine head of the utility model.
