Description
Technical field
The utility model belongs to fiberglass production technical field, and in particular to one kind becomes die cavity pipe profile mould.
Background technology
Traditional glass steel pultrusion pipe profile dies cavity import does not have any change to outlet size, and fiberglass is in mould
Colloidal state is changed into from liquid during the solidification of tool inner chamber, solid-state is changed into from colloidal state, volume constantly changes in this section of change procedure；
When shrinking, amount of contraction (because die size does not change) can not be compensated with mould, so causing resistance larger, section produces
Crackle, surface roughness are poor, tractive force also increases etc. causes that pultrusion low production efficiency, product strength are poor, tractive force is big and power consumption
Amount is big.
Utility model content
The defects of the purpose of this utility model is to overcome in the prior art, and a kind of reasonable in design, production is provided
The product cross section that resistance is small, power consumption is small, produces does not have high micro-crack, surface smoothness, intensity height and production efficiency high
Become die cavity pipe profile mould.
What the purpose of this utility model was realized in：The mould includes pre-shaping device, is located at pre-shaping device end
Mould external mold, the outer surface of mould external mold is provided with preceding heating plate and rear heating plate, mould inner mould core is provided with inside mould external mold,
Die inlet is formed between the front end of mould external mold and mould inner mould core, is formed between the end of mould external mold and mould inner mould core
Mould outlet, described mould inner mould core are round estrade, and the big bottom surface of round estrade is arranged on the front end of mould external mold, round estrade
Small bottom surface is arranged on the end of mould external mold, and the cone angle of the round estrade is 0.4: 1000.
The utility model has reasonable in design, and production resistance is small, power consumption is small, the product cross section produced is not micro-
The advantages of crackle, surface smoothness are high, intensity is high and production efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the position relationship schematic diagram of the utility model mould external mold and mould inner mould core.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, now control illustrates
Specific embodiment of the present utility model, in the various figures identical label represent identical part.To make simplified form, in each figure
The part related to utility model is only schematically show, they do not represent its practical structures as product.
As shown in Figure 1, 2, the utility model becomes die cavity pipe profile mould to be a kind of, and the mould includes pre-shaping device 4, if
Mould external mold 6 in the end of pre-shaping device 4, the outer surface of mould external mold 6 are provided with preceding heating plate 7 and rear heating plate 5, outside mould
The inside of mould 6 is provided with mould inner mould core 3, and die inlet 2, mould external mold are formed between the front end of mould external mold 6 and mould inner mould core 3
Mould outlet 1 is formed between 6 end and mould inner mould core 3, described mould inner mould core 3 is round estrade, the big bottom of round estrade
Face is arranged on the front end of mould external mold 6, and the small bottom surface of round estrade is arranged on the end of mould external mold 6, the cone angle of the round estrade
For 0.4: 1000.
Production technology of the present utility model is：1st, interior glass mat enters the interior felt looping pit of pre-shaping device 4, glass
Silvalin enters the inside and outside glass mat of the annular porous that is evenly distributed of pre-shaping device 4 into the outer ring of pre-shaping device 4
Hole, the function of pre-shaping device 4 are：Make glass mat and glass fiber yarn without any confusion into die inlet 2 specify
Position.2nd, glass mat and glass fiber yarn are pulled into die inlet 2 by hauling machine, by unnecessary unsaturated polyester (UP) tree
Fat is smoothed out with the fingers, and is gone successively in mould intracoelomic cavity.3rd, glass mat and glass fiber yarn add before being pulled into by hauling machine
Hot-zone, unsaturated polyester resin is become into colloidal state by liquid in the presence of preceding heating plate 7；4th, glass mat and glass fiber yarn
Continue to be pulled into rear heating zone by hauling machine, by the glass fibers containing unsaturated polyester resin in the presence of rear heating plate 5
Dimension is become by colloidal state turns to uniform solid-state.5th, glass fiber reinforced plastic shapes continue run backward after mould outlet 1 turn into surface it is smooth,
The very high frp pipe of intensity.Mould inner mould core 3 is round estrade in the utility model, and its essence is to make to increase in dies cavity
Cone angle, fiberglass will shrink in mould in solidification process, and variant mould (both the import of mould to outlet size was changing) can be mended
Repay expansion or shrinkage amount；Change of the raw material in mould, which turns to, first to be expanded after-contraction, is changed into colloidal state from liquid, being changed into solid from colloidal state
State, volume also constantly changes in this section of change procedure.Because die size also constantly changes, raw material expand when by mould outside
Mould 6 (mould exocoel) ensures, resistance is smaller, section does not crack when being met by dies cavity during contraction, therefore produced,
Surface roughness is improved, solves the defects of conventional tube section bar mold production.In addition, it can be seen from applicant's many experiments
When cone angle is 0.4: 1000, best results.It should be noted that the utility model is only limited to use in ring mould；This practicality
Preceding heating plate 7 and rear heating plate 5 described in new can be heating ring；By said apparatus and coordinate above-mentioned technique, can
Production efficiency is improved up to 15% or so, tractive force during production can reduce 5%, and having reduces enterprise's production cost, improves product
The characteristics of quality and energy-conserving and environment-protective.
, it is necessary to illustrate in description of the present utility model, unless otherwise clearly defined and limited, term " setting ",
" connection " etc. should be interpreted broadly, for example, it may be being fixedly connected, be integrally connected or be detachably connected；Also may be used
To be the connection of two element internals；Can be joined directly together, can also be indirectly connected by intermediary, for this area
For those of ordinary skill, concrete meaning of the above-mentioned term in the utility model can be understood as the case may be.Above
Describe illustrating only for feasibility embodiment of the present utility model in detail, they simultaneously are not used to limit this practicality
New protection domain, all equivalent implementations made without departing from the utility model skill spirit, change and transformation all should wrap
It is contained within the scope of protection of the utility model.
