Specific embodiment
The utility model is further described With reference to embodiment:
As an example, the non-equal wall thickness of the present embodiment squeeze out profile mold, for for structure D shown in Fig. 1
Extrusion profile mold, as shown in Figures 2 and 3 comprising extrusion die 1 and stock mould 2.
Specifically, together refering to what is shown in Fig. 4, extrusion die 1 includes machine neck 11, the first flow distribution plate 12, fixing piece 13, second
Flow distribution plate 14, constriction plate 15, heating device 16, temperature control part 17, mouth mold 18 and mold core 19, wherein machine neck 11, the first flow distribution plate
12, the second flow distribution plate 14, constriction plate 15 and mouth mold 18 are set gradually along extruded material flow direction, four screws successively drawing-in
It after two flow distribution plates 14 and the first flow distribution plate 12, is spirally connected with machine neck 11, and then by the second flow distribution plate 14, the first flow distribution plate 12 and machine neck
11 are fixedly clamped；It there are four after bolt successively drawing-in mouth mold 18 and constriction plate 15, is spirally connected with the second flow distribution plate 14, and then by mouth
Mould 18, constriction plate 15 and the second flow distribution plate 14 are fixedly clamped；There are two after bolt drawing-in mold core 19, mould corresponding with constriction plate 15
Screw hole at core 19 is spirally connected, so that the position of mold core 19 is fixed, and is located at the cavity at 18 middle part of mouth mold.Fixing piece 13 passes through
The effects of two-screw is connected and fixed with the second flow distribution plate 14, plays clamping first flow distribution plate 12 and the second flow distribution plate 14, anti-overflow.
The top of second flow distribution plate 14 offers the feed inlet flowed into for the extruded material of other colors or material, the feed inlet
The screw hole there are four for connection is set around place, which when not used, can be sealed by bolt, to avoid extruded material from this
It overflows at place.Temperature control part 17 is in the shape of a frame, and is set in the periphery of mouth mold 18, and the inner surface of temperature control part 17 is temperature control face, and three mutually
Between independent heating device 16 respectively correspond three temperature control faces and be arranged on temperature control part 17.
As shown in figure 4, stock mould 2 includes upper cover plate 21, shaping cover 22 and lower cover plate 23, upper cover plate 21 and lower cover plate 23 divide
Not Tong Guo four screws connect with the upper and lower parts of shaping cover 22, the front side of shaping cover 22 is equipped with water pipe head, shaping cover 22
Rear side is equipped with vacuum adapter, and the inside of shaping cover 22 is equipped with the corresponding pipeline for cooling down sizing.
In use, the machine neck 11 of extrusion die 1 is connect with the extrusion of extruder, the feed inlet of the second flow distribution plate 14 with
The extrusion of another extruder connects, and heating device 16 is connect with control device, and stock mould 2 is mounted directly to shaping platform, squeezes out
It is connected between die head 1 and stock mould 2, then carries out the roasting material that heats up, run extruder, carry out extrusion molding production, specifically,
During formed product, the first shunting is flowed through by the molten state plastics that the extruder that machine neck 11 carries out transition drainage passes over
Plate 12, the second flow distribution plate 14, the molten state plastics flowed into the feed inlet by the second flow distribution plate 14, in constriction plate 15, Kao Kou
It is preforming to converge progress at mould 18, finally enters stock mould 2 and realizes structure sizing, can so produce double-colored extrusion profile and produce
Product.
It is individually controlled since the temperature control at the mouth mold 18 of extrusion die 1 is adjusted to three faces, so in product extrusion molding,
Temperature-controllable is stronger, and each face can adjust temperature by the manipulation to heating device 16, i.e., according to the extrusion situation of product
Control flows through the corresponding temperature for squeezing out the extruded material at profile different wall thickness at mouth mold 18 respectively, and then realizes and adjust each correspondence
The gel quantity that position squeezes out keeps extruded product size more steady to keep the non-each position wall thickness for waiting wall thickness product more controlled
It is fixed, keep production qualification rate higher.
After being squeezed out due to product, thicker position can compare difficult cooling, so special designing has also been carried out on stock mould, even if
Squeeze out at least one numerical value in the wall thickness of profile and the length of stock mould 2, stock mould 2 in the quantity of water route and/or vacuum tank
It is proportional.For example, individually add the pipeline that a Cooling Water flows through for the position of product thickness, while by the length of stock mould
It lengthens, general sizing system design length 120-150mm, the length of the present embodiment stock mould 2 is 180mm, and it is fixed to be promoted in this way
The sizing of pattern 2, cooling capacity, can guarantee enough cooling and shaping effects in this way, and the position for keeping product thicker can also be filled
Divide cooling and shaping, this is conducive to promote product structure precision, and promotes product that can be formed under slave mode.
It should be noted that profile mold can also be squeezed out according to above-mentioned non-equal wall thickness, designs and tied in Fig. 1
The mold of structure A, B or C have one on mouth mold section temperature control mode although having some architectural differences between mold each in this way
A little variations, but the thinking for designing local warming's control is consistent, i.e., is all the temperature control for the partially thick position of product being added part
And cooling and shaping does so preferably to control the parameters such as product structure, size and shape while can also reduce mold
Repair a die number, shortens the development cycle of mold.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations all should belong to the protection scope of the appended claims for the utility model.
Illustrative description has been carried out to the utility model patent above, it is clear that the realization of the utility model patent not by
The limitation of aforesaid way, if the method concept of the utility model patent and the various improvement of technical solution progress are used, or
It is not improved that the conception and technical scheme of the utility model patent are directly applied into other occasions, in the utility model
In protection scope.
