Description
Technical field
The utility model relates to plastic section extruding field, particularly relates to the extrusion shaping machine of a fairly large number of multi-cavity profile shapes sizing of interior muscle.
Background technology
Plastic-profile extrusion-molding technology is a kind of parison extrusion die being made melting by extruder heating, pressurization, through a continuous process of the cooling fast of dry type sizing, wet type sizing (water tank), solidification.For the multi-cavity profile shapes that interior muscle number ratio is more, die head heating causes interior muscle heat larger, parison makes to be forced cooling and shaping in stock mould die cavity due to hollow negative-pressure adsorption, because outside wall surface first cools, and muscle quantity is many in parison, cool after interior muscle, interior muscle heat can not get timely discharge, impel profile shapes parison in stock mould, be in uneven cooling and stress, produce cooling stress, these stress can cause interior muscle to bend adhesion, and shape deforms, affect the apparent mass of section bar, even the physical property of section bar is had an impact.
Utility model content
The purpose of this utility model solves muscle in multi-cavity profile shapes to bend adhesion problems, there is provided a red interior muscle can abundant cooling and shaping, eliminate the cooling stress of parison in stock mould, avoid interior muscle to occur bending adhesion, ensure the extrusion shaping machine of muscle glacing flatness in special section.
The technical solution adopted in the utility model is: a kind of extrusion shaping machine for the sizing of multi-cavity profile shapes, comprise extruder, extrusion die, stock mould, water tank, shaping platform, hauling machine and crawler belt, described extrusion die comprises mouth template affixed successively, pre-plate, compressive plate, support core, rebound, support spreader and machine neck, the affixed air blowing joint of described rebound, described mouth template is provided with gas hole, described gas hole is connected with air blowing joint by air drain, described mouth template, pre-plate, compressive plate, support core and rebound are respectively equipped with air drain and are interconnected.
As further improvement of the utility model, the interior muscle gap of described gas hole and mouth template is suitable.
The beneficial effect that the utility model adopts is: the utility model designs an air blowing joint at die head rebound place, blown by die head exit end, force section bar before entering stock mould, interior muscle can abundant cooling and shaping, eliminate the cooling stress of parison in stock mould, avoid interior muscle to occur bending adhesion, ensure muscle glacing flatness and shape and size precision in special section, make up design not enough, expand the adaptive capacity to expressing technique.

Shown in figure: 1 extruder, 2 extrusion dies, 3 stock moulds, 4 water tanks, 5 shaping platforms, 6 section bars, 7 hauling machines, 8 crawler belts, 21 mouth templates, 22 pre-plates, 23 compressive plates, 24 support cores, 25 rebounds, 26 support spreaders, 27 machine necks, 211 gas holes, in 212 muscle gap, 251 air blowing joints.
Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, the utility model is described further.
As shown in the figure, a kind of extrusion shaping machine for the sizing of multi-cavity profile shapes, comprise extruder 1, extrusion die 2, stock mould 3, water tank 4, shaping platform 5, hauling machine 7 and crawler belt 8, described extrusion die 2 comprises mouth template 21 affixed successively, pre-plate 22, compressive plate 23, support core 24, rebound 25, support spreader 26 and machine neck 27, the affixed air blowing joint 251 of described rebound 25, described mouth template 21 is provided with gas hole 211, described gas hole 211 is connected with air blowing joint 251 by air drain, described mouth template 21, pre-plate 22, compressive plate 23, support core 24 and rebound 25 are respectively equipped with air drain and are interconnected.
Gas hole 211 is suitable with the interior muscle gap 212 of mouth template 21, makes interior muscle gap 212 can by the air-flow institute admittance in gas hole 211.
Powder or granulated plastic plastify from extrusion die 2 extruded parisons by extruder 1, enter and enter water tank 4 after stock mould 3 carries out preliminary cooling forming and further cool and shape, shaping platform 5 provides necessary cooling medium and vacuum to stock mould 3 and water tank 4, by the traction of crawler belt 8 in hauling machine 7, finally obtain quantity-produced section bar 6.
When plastic parison is extruded continuously from extrusion die 2, by blowing to the air blowing joint 251 on rebound 25, gas is arrived in each gas hole 211 of die head exit port template by pore and air drain, thus realizes the effect that internal muscle carries out blowing.Blowing in each interior muscle gap 212 of each gas hole of die head exit port template 211 pairs of mouth templates, ensures that each interior muscle of mouth template reaches the object of cooling fast, avoids interior muscle to occur bending adhesion.
Fig. 4 is the bending adhesion of interior muscle appearance after not blowing, and Fig. 5 is that the rear interior muscle of air blowing is in straightened condition.
The utility model designs an air blowing joint at die head rebound place, blown by die head exit end, force section bar before entering stock mould, interior muscle can abundant cooling and shaping, eliminate the cooling stress of parison in stock mould, avoid interior muscle to occur bending adhesion, ensure muscle glacing flatness and shape and size precision in special section, make up design not enough, expand the adaptive capacity to expressing technique.
Those skilled in the art should know; protection scheme of the present utility model is not limited only to the above embodiments; various permutation and combination and conversion can also be carried out on the basis of above-described embodiment; under the prerequisite without prejudice to the utility model spirit, the various conversion that the utility model carries out all are dropped in protection domain of the present utility model.
