Abstract
The utility model is related to a kind of extrusion die, including extrusion die, extrusion die includes mold and lower mould, and the middle part of mold sets the first radiator, the middle part of lower mould sets the second radiator, mold and lower mould to be used after being tightened together by fastening bolt.The utility model extrusion die, it is simple in construction, it is easy to operate, efficiently solve because fused materials are heated the problems such as uneven PVC foam plate thickness that causes is uneven, plate face is scared in a mold, quality of item is improved, production cost is reduced, production efficiency is improved.
Description
Technical field
The utility model is related to a kind of extrusion die.
Background technology
In the prior art, when preparing PVC foam wide plate, often because mould centre heat is not distributed not come out, in causing
Between fused materials because of local overheating, discharge uneven, cause PVC foam plate uneven distribution even, cause thick middle, both sides are thin to ask
Topic, simultaneously because middle local temperature is too high, foaming is excessive, causes foaming product middle part surface scared, decorative pattern occurs, causes plate
Face Quality Down, has a strong impact on the performance of product.Those skilled in the art, by changing raw material, adjust formula etc. still not
It can settle the matter once and for all.Symptom can only be mitigated, it is impossible to eradicate, and production cost rises caused by being formulated adjustment, is badly in need of one
Plant the method that can solve the problem that the problem.
Utility model content
The purpose of this utility model is to provide a kind of extrusion die, simple in construction, easy to operate, efficiently solves due to thing
The problem of material is heated that the uneven PVC foam plate thickness that causes is uneven, plate face is scared, decorative pattern occurs in a mold, improves system
Quality, reduces production cost, improves production efficiency.
A kind of extrusion die of the utility model, including extrusion die, extrusion die include mold and lower mould, mold
Middle part the first radiator is set, the middle part of lower mould sets the second radiator, and mold and lower mould are tight by fastening bolt
Gu use afterwards together.
In use, the extruded mould extrusion molding of melt foaming material that the extruded machine of material has been plastified, through cooling and shaping
Afterwards.
The position of position and the second radiator on lower mould of first radiator on the upper mold is to be symmetrical arranged, both
Line it is perpendicular to the ground, the height of the first radiator is higher than the height of the second radiator.
Mould sets bolt hole.
Bolt hole is mainly used in installing fastening bolt, and upper/lower die is tightened together, and completes the extrusion molding of material.
Extrusion die is connected by merging core, transition body with extruder.
First radiator is provided with to set on heat dissipation base, heat dissipation base sets fin on cooling stand, cooling stand.
Heat dissipation base bottom sets mounting groove.
Cooling stand is Y types, and the fin of the upper space of cooling stand Y types is vertical direction, the two of cooling stand Y types
The fin of side is laterally.
Heat emission hole is set in the middle of cooling stand.Heat emission hole can improve radiating efficiency.
Because melting material temperature is uneven in extrusion die, medium temperature overtemperature is too high, and two sides temperature is low, causes in material
Between flow velocity it is fast, it is thin to ultimately result in PVC foam plate both sides, thick middle.
Again because the heat of middle part friction accumulation is high, it is difficult to dissipate under normal circumstances, it is easy to cause melting in the middle part of mould
Temperature of charge is too high, and foaming is excessive, and thickness is partially thick, and arrow shaped decorative pattern occurs in plate face, has a strong impact on board surface quality.Therefore, will be big
The radiator that small, length, height, thickness are not quite similar is placed in the middle part of extrusion die wide cut.The number of radiator, root on mould
According to overtemperature degree, it is determined that the radiator put on the specification of quantity and selection thermal component, mold and lower mould is symmetrical
Addition.Wherein, overtemperature is the temperature difference beyond mould set point of temperature.
The structure of first radiator and the second radiator is identical, and height is different.
Compared with prior art, the utility model has the advantages that：
The utility model extrusion die, it is simple in construction, it is easy to operate, efficiently solve due to fused materials in a mold by
The problems such as uneven PVC foam plate thickness caused of heat is uneven, plate face is scared, improves quality of item, reduces production cost,
Improve production efficiency.
