Description
Technical field
The present invention relates to a kind of blow moulding machine more particularly to a kind of foaming blow moulding machines and its fretting map hollow forming method.
Background technique
Blow moulding machine be it is a kind of sealant is gushed out after, plastomer is blown and is attached to one by the wind-force produced by boasting using machine
The die cavity of setting shape, so that the machine of product be made.Plastics are melted in screw extruder and squeezing out quantitative, then pass through mouth
Film molding, then have vane quenching, then there is dragger to draw by certain speed, up- coiler is wound into volume.
The product that existing blow moulding machine is usually produced is harder, is not able to satisfy the demand of certain field products, and by blowing
The common PE plastics of molding machine production all have biggish lack in reverse side such as quality, sound insulation, insulation, heat preservation and energy-saving and emission-reduction
It falls into.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide a kind of save the cost, high production efficiency and productions
The measured foaming blow moulding machine of quality.
To achieve the goals above, present invention employs technical solutions below:
A kind of foaming blow moulding machine, including automatic suction machine, extruder, pump-up device and blow moulding machine, the extruder include
Hopper, in-material seat, barrel and screw rod, the hopper are fixedly connected with one end of barrel by in-material seat, the automatic suction machine
It is connected to hopper, the screw rod is arranged in barrel and is driven by motor, and the outside of the barrel is also enclosed with electric heating piece, described
Screw rod is additionally provided with far from one end of automatic Packing Machine inflates hole, the pump-up device be fixed on blow moulding machine side and with inflate Kong Lian
It is logical；Blow moulding machine includes storing coventry type die head coventry, mold and die drive unit, and the storing coventry type die head coventry is connected to the other end of barrel,
The mold is molded and is divided mould by die drive unit driving, and the die-closed position of mold be located at storing coventry type die head coventry just under
Side.
As a preferred solution: further including manipulator, the front of storing coventry type die head coventry lower part is arranged in the manipulator.
A second object of the present invention is to provide a kind of fretting map hollow forming method, using above-mentioned foaming blow moulding machine,
And use following steps:
1) colour masterbatch containing foaming agent, is added in PE material to mix according to a certain percentage, then by automatic
Material sucking machine is drawn onto the hopper of extruder, and material enters barrel by in-material seat；
2) frictional heat, generated by the rotational shear of screw rod and the electric heating piece being wrapped in outside barrel heat to melt original
Material, the raw material melted pass through the front end for being further conveyed to screw rod of screw rod,
3) it, is connected to pump-up device in the hole of inflating of the front end of screw rod, pump-up device nitrogen bubble will get to melting one by one
Raw material in, be then evenly distributed in bubble in fused raw material by screw head, added with the fused raw material of nitrogen bubble
It is expressed in storing coventry type die head coventry by the further conveying of screw rod, storing coventry type die head coventry starts pressure holding function at this time；
, etc. 4) storing amount reaches shooting condition inside storings coventry type die head coventry, is switched on shooting oil cylinder, material is shot out, wait material
Certain length is penetrated, then again by mold clamping, then gas-blowing foaming is formed, and wait products cooling, die sinking, artificial or manipulator handle
Product takes out, and removes edge grinding.
The foaming blow molded product of the device of the invention production has the following aspects compared to the advantage of conventional blown product:
1. safety guarantee: as auto parts and components, common PE plastics are harder, if traffic accident, PE plastics occur for automobile
It probably fractures because of collision, generates wedge angle, can cause harm to the human body.Foamed plastic toughness is very good, and impact strength is high,
When colliding, only meeting bending deformation, avoids result above.
2. saving cost of material: with constantly rising violently for the prices of raw materials, bringing huge punching to plastics manufacturing
Hit, foaming forming technique carrys out filled articles mainly by the expansion of stomata, saved the use of raw material in production process, product at
This can usually reduce by 20%~30%, be a kind of means of long-term save the cost.
3. automotive light weight technology: foaming blow molding process can allow the producer of auto parts and components by mitigating automotive plastic parts
Weight realize integral automobile lightweight, under the premise of guaranteeing the intensity and security performance of automobile, reduction vapour as much as possible
The total quality of vehicle reduces fuel consumption to improve the dynamic property of automobile, reduces exhaust pollution.
4. sound insulation, insulation, heat preservation and energy-saving and emission-reduction: as air conditioning for automobiles air hose, compared to solid plastics with high hardness
For product, foaming product sound insulation, insulation effect is more preferable.When wind enters air conditioning wind pipe, the bubble being distributed on product can
Effective heat preservation, to achieve the effect that energy-saving and emission-reduction.
5. effectively improving production efficiency: foaming blow moulding machine is furnished with specific customization screw rod, and back pressure can not only increase in screw rod
Extruded velocity can also make the material embryo squeezed out more steady, uniformly.In addition the foamed material embryo after extrusion is than common material embryo density
It is low, it is easier to it blows, forms, it is cooling, the molding cycle of product is effectively improved, raising production efficiency is more advantageous to.
6. improving buckling deformation and size being accurate: buckling deformation is more scabrous system common in conventional plastic production
One of product defect, it is mainly product due to stress and shrinks uneven and generate.Due in entire foaming forming technique,
Product is under average gas pressure always, ensure that the uniform shrinkage of different location, while improving buckling deformation, foaming work
Skill guarantees the support stability of product also by the allowance control of product in desired interval range.
