In the utility model, through the gas channel of mould inside, to mould inside air blowing supercharging, raw materials melt, by core rod and the sizing of mouth mould, is waited to arrive supercharging core rod position, due to mould inside supercharging, tubing sizing under the effect of pressure differential, under the effect of mould supercharging core rod position spiral circulation water, tubing cools sizing of tentatively shaping fast, then can complete the production of tubing through the cooling water tank the final shaping sizing of inner wall belt tapering shaping cover.
The utility model cooling sizing part adopts spiral cooling water channel cooling capable of circulation, adopts the shaping cover cooling twice sizing of inner wall belt tapering; Can to blow supercharging to mould inside, the raw material forming air pressure official post molten condition is shaped between core rod and mouth mould;
The utility model does not need to vacuumize sizing, eliminates the equipment that outside vacuumizes simultaneously, saves device fabrication cost, and mould adopts spiral cooling water channel cooling capable of circulation, and make cool time short, cooling effect is better; When tubing produced by this mould, the process completing preliminary sizing sizing on mould can be realized; When tubing produced by this mould, the use of cooling water tank and vaccum-pumping equipment can be reduced, greatly save production equipment manufacturing cost and equipment placing space, reduce energy resource consumption high, save production cost.
Compared with prior art, beneficial effect is:
1, this mould forms by shaping partly and cooling sizing two department, and cooling sizing part and die head are connected to form an entirety, save space.
2, this mould adopts inner mode supercharging of blowing, and produces the sizing of pressure official post tubing.
3, this mold cools down part adopts spiral cooling water channel capable of circulation, and cooling velocity is fast, can realize tentatively cooling sizing on mould.
4, again by the shaping cover with tapering on water tank after tentatively cooling, can better shape and improve the fineness of tube surfaces.
5, adopt this new type plastic pipe production mould to produce tubing to save vaccum-pumping equipment greatly and reduce the use of cooling water tank, also the auxiliary equipment vacuumized is reduced, save device fabrication cost, also reduce the use of the device space and the consumption of the energy simultaneously, reduce production cost and maintenance cost.
